Residence Organ

Tradition and Development

by Francesco Ruffatti

A concert by Luigi Ferdinando Tagliavini and Gustav Leonhardt at the Basilica of San Petronio in Bologna, held on October 27, 2000, provided the inspiration for  writing an article on the historical Italian organ, its tradition and development. My goal is to give a panoramic view of the subject, and anyone knows that when looking at a panoramic view much of the detail is lost. Still, such an attempt is worth carrying out because some general guidelines can in any case be drawn. To do so, it is necessary to go back a number of centuries and try to understand the original role of the organ in the musical world of Italian churches.

 

The Basilica of San Petronio is no ordinary place from the standpoint of organbuilding history. It enjoys the presence of two unique instruments: the oldest Italian organ in existence, built by Lorenzo da Prato between 1471 and 1475, roughly 20 years prior to the discovery of America by Columbus,1 and a later organ, built by Baldassarre Malamini in 1596. The instruments are located face to face in the area traditionally reserved for the choristers, behind the high altar.

The program notes for the Tagliavini-Leonhardt concert, written by Marc Vanscheevwijck, well explain the use for which organs of medieval and renaissance times were intended:

Alternatim performance practice, i.e., the performance of liturgical pieces alternating contrasting musical forces in the various versets of the sacred texts, originates in the old antiphonal singing of psalms of the first centuries A.D. In responsorial music a soloist or a small group of singers alternated with the larger choir. Sometimes they alternated plainchant with polyphonic settings of the text. Probably as early as the organ began to be used in church, the organist already improvised "versets," alternating with the choir singing the counter versets in Gregorian chant. Obviously, the schola never repeated the texts of the versets played by the organist, who improvised (and later composed) on the relative Gregorian melodies. The earliest source of such a practice is the Faenza Codex, compiled c.1420. During the following century this alternatim practice spread throughout Italy. Many alternatim settings, particularly of the mass proper, have been preserved, some of the most famous of which were composed by Girolamo Cavazzoni, Claudio Merulo, Andrea Gabrieli, and (in the 17th century) the Fiori Musicali of Girolamo Frescobaldi.2

 

Two aspects immediately come to mind:

1. The organ location, which for effective responsorial use had to be near the choir and not necessarily in a favorable position for the congregation,

2. A tonal structure suitable for dialogue with a small group of singers.

There was no need for a sound big enough to accompany the choir, simply because the organ was intended as a soloist. And accompanying the congregation was certainly not in the agenda, since people did not sing during liturgy in Italian Catholic churches until very recently.3

What effect did all of this have on the sound? Since power was not the issue, early Italian organbuilders developed their talents in other areas, and tonal quality became the priority. They created relatively small instruments, mostly with only one manual, with gentle, beautifully voiced stops. Wind pressures were in most cases quite low, down to 42-45 mm. at the water column, and the voicing techniques as well as the tonal design in general reflected such an approach.

Listening to music by Antegnati (also a famous Italian organbuilder), Segni, Veggio, Gabrieli and others performed on the beautiful organs of San Petronio gave me and the entire audience (a few hundred people all gathered in the large space behind the high altar, to be able to best hear the organs) a good perspective of the musical experience which was originally expected from such instruments.

It is my belief that the original DNA of ancient Italian pipe organs, as defined by their original use in the liturgy, played a decisive role in the subsequent evolution of the instruments. This was due to a strong sense of tradition among the vast majority of builders and to their reluctance to introduce changes to a practice which was considered successful. Examples to the contrary do exist, but any effort of generalizing, or extracting general rules from a complex reality, always ends up sacrificing notable exceptions.

In post-Renaissance times, organ use became widespread. All Italian churches had at least one organ and often one or two Positivo4  instruments in addition to the main organ. And a very significant change took place: in addition to being used as a solo instrument for improvisations and for the performance of written music, the organ also became an accompanimental instrument for the choir. Its location within the building also changed in most cases, taking into greater consideration the congregation as the beneficiary of musical performances: the preferred location for new instruments became a balcony facing the nave, which is still considered by many to be the ideal location for the best possible diffusion of sound within a building. Naturally, broader tonal resources had to be made available in order to accommodate this new function, but this did not cause a significant change in the original voicing practices. In other words, more stops were introduced and a Pedal division was added (normally consisting of one or two stops), but the basic tonal structure remained the same and no major changes took place in the sound: still low pressures and gentle voicing. After all, organs still did not need to be big or powerful, because they were not intended to support an entire congregation, just a choir.5

A further, major evolution took place as a result of the greater demands by the repertoire of the Romantic period. A great number of new stops were introduced: reeds of various types, more flutes, strings, even percussion: drums, cymbals, bells and the like. The organs built by the Serassi family of Bergamo towards the end of the eighteenth century and during the following century are a good example of the romantic Italian organ. The occupation of Bergamo by the troops of Napoleon (1796-1813) and subsequently by the Austrians (1814-1859) influenced organbuilding practices by introducing new musical models and, as a consequence, by contributing to the development of new devices and new sounds that would improve the performance of the music inspired by the teaching of Simon Mayr (1763-1845), by his pupil Gaetano Donizetti (1797-1848) and by Gioacchino Rossini.6 The famous composer Felice Moretti (also known as Father Davide da Bergamo), a Franciscan monk and a family friend of the Serassi, composed music that was deeply influenced by opera. Also, Giuseppe II Serassi, the most innovative member of the family, introduced new devices aimed at facilitating the dynamic control of sound: the third hand, or mechanical super coupler, the fourth hand, or sub coupler, the expression shades, pedals for pre-set combinations of stops, an easier system for the coupling of the manuals (by means of a pedal and no longer by the sliding of the upper manual into position), settable combinations of stops, and the Tiratutti or Tutti for the Ripieno ranks.7

In spite of all of this, the ancient core of the instrument and the basic tonal concept behind it remained virtually unchanged for a good part of the nineteenth century. Low wind pressures were still the rule, as well as unforced voicing, fairly open pipe toes, and few nicks at the languids. As a consequence,   there was a broad harmonic development in the sound, allowing a very effective use of each stop in combination with others and forming an ensemble of rare cohesion and beauty. Pressures of sometimes less than 50 mm. at the water column naturally presented a real challenge, particularly for the voicing of reed stops, but this had the effect of encouraging builders to find original design and voicing methods to overcome the difficulties.8

At this point, it is necessary to define the tonal core of the organ which I have indicated as an element of continuity in Italian organbuilding throughout the centuries. Its main component is the Ripieno. The term does not translate to Mixture, but rather it defines a series of individual Principal scaled ranks of pipes at various pitches, creating a system of sounds at harmonic intervals, normally beginning with 8' pitch as the foundation of the manual.

The composition of a typical Ripieno with its traditional nomenclature follows:

Principale (I) 8'

Ottava (VIII) 4'

Decimaquinta (XV) 2'

Decimanona (XIX) 11/3'

Vigesima seconda (XXII) 1'

Vigesima sesta (XXVI) 2/3'

Vigesima nona (XXIX) 1/2'

Trigesima terza (XXXIII) 1/3'

Trigesima sesta (XXXVI) 1/4'

And occasionally:

Quadragesima (XL) 1/6'

Quadragesima Terza (XLIII) 1/8'

The highest pitch in the entire Ripieno is in most cases the note C at 1/8'. Beyond this limit a ritornello or break begins with pipes double the length, or one full octave lower in pitch.9

Table 1 is intended to give a clear and comprehensive idea of the tonal composition of the Ripieno. The method I am utilizing is unconventional and it consists of identifying each pipe by a number corresponding to its place in an ideal succession of notes starting with number 1 as low C of the 8' Principal. Low C at 4' will consequently be numbered as 13, low C at 2' will be numbered as 25 and so on. The highest pitch pipe in the Ripieno will be number 73, corresponding to the pitch limit of 1/8'. Once a rank reaches note number 73 it will break back and start a ritornello with note C#62 (or one full octave lower). To simplify matters, I am showing the first octave as complete (12 notes). The most common arrangement in Italian historical organs calls for a short first octave (8 notes, with C#, D#, F# and G# missing). Notes are identified by octave number, according to the Italian system, by which C1 corresponds to note C of the first octave, F3 to note F of the third octave, and so on. The chosen compass for our example is of 49 keys, C1 to C5. This system, by numbers rather than by footage, is intended to provide a more immediate idea of the repetition of equal size pipes throughout the compass for the entire Ripieno. Equal number means equal size pipe.

The conventional method is shown in Table 2. The Ripieno here is comparable, in pure terms of number of pipes, to a Principal chorus with 8', 4' and 2' stops plus a six-rank mixture. But by looking at Table 2 one can immediately appreciate the vast difference from such an arrangement. At note C#2 the first doubling or double pitch appears: pipes from the 1/2' rank (XXIX) and 1/4' rank (XXXVI) become of identical size. Consequently, between notes C#2 and F2 the tonal effect is not that of a six-rank mixture but rather of a five-rank mixture with one of the ranks doubled. This aspect becomes more and more prominent as we move up the keyboard, to the point that at note C#4 (key number 38) with all ranks from Decimaquinta (2') up drawn, only two pitches can be heard: 2', repeated 4 times, and 11/3', repeated three times. As one can easily appreciate, such tonal structure cannot be compared with that of a Mixture, or Fourniture or any other multiple-rank stop designed as a single entity. The Ripieno is simply different. It is conceived as a sum of individual ranks at different pitches, each separately usable in combinations with any other rank and all usable at once as a pleno.10

Obviously, this feature provides a great deal of flexibility in the tonal palette. From an organbuilder"s practical standpoint, it has two effects:

1. It forces the voicer to be extremely scrupulous as to the tonal balance, regulation and speech adjustment of each pipe even in the highest pitched ranks, since each can be separately used;

2. It makes tuning more difficult, due to the drawing effect on the equal pitched pipes when they play together. Only a tuner who knows how to deal with such a problem can obtain a stable tuning of the Ripieno.11

Tuning with double pitches was nothing new to ancient builders. In fact, pre-Renaissance and Renaissance organs, in Italy as well as in other European countries, often had double or even triple notes of equal length in the treble of the Principal, the Octave and sometimes the Fifteenth, to enhance the singing qualities of the instrument in the treble. This practice strangely survived, in some areas of Italy, all the way to the beginning of the 19th century. This proves that the difficulties connected with the tuning of multiple equal-pitched pipes never bothered Italian organbuilders too much.12

Other traditional stops forming the original core of the historical Italian organ include the following:

Flauto in Ottava (4'), normally tapered or cylindrical, sometimes stopped

Flauto in Decimaquinta (2') in the earlier instruments

Flauto in Duodecima (22/3')

The Terzino, or Tierce flute (13/5') was later added and, in the nineteenth century, the Flauto Traverso or Fluta (8', normally in the treble only).

Early strings appeared in the eighteenth century, at 4' in the bass and occasionally over the entire compass, but such stops were vastly different from what we think of as a string today. They had no ears, no beards, no nicks at the languids. These characteristics, combined with a very narrow scale, contributed to produce a sound with a very prominent transient at the attach and a cutting sustained tone, strongly imitative of early string instruments.

The Voce Umana or Fiffaro, a Principal-scaled stop at 8' pitch (treble only) was also used in the Renaissance and became increasingly more common in the Baroque and later periods. Its pipes were normally tuned sharp against the 8' Principal, except in the Venetian tradition and among a few builders in the south of Italy, where flat tuning was preferred.

The above description, as I have said earlier, represents a simplification of a much more complicated subject, and many examples exist that do not follow the rule.13 Also, all of those who are familiar with ancient Italian organs will agree that the tonal experience that comes from a Callido or a Nacchini organ is vastly different from that of an Agati or a Catarinozzi. They were expressions of very different artistic environments and the builders were very faithful to their own local traditions.

What happened in nineteenth-century Italian organbuilding is worth investigating a bit more closely. Early signs of rejection of the Italian romantic organ appeared. In 1824 the Cardinal Vicar of Rome promulgated an edict stating: "Organists may not play on the organ music written for theater, or with profane character, but only music that can encourage meditation and devotion . . . "14 Still, many of the major builders in the north, as well as many in other parts of the country, continued in their tradition of building instruments without changing their style.15 But at some point, foreign influence became a strong factor16 and the "new inventions," the Barker lever first and then pneumatic and electric action, came into the picture.17 Pneumatic action in particular and the new sounds, such as the "modern strings" and harmonic stops demanded higher wind pressures, and the organ sound became stronger and aggressive. But, as we all know, pneumatic action represented only a relatively short transition period in organbuilding history, and a further evolution of the instrument was soon marked in the following century by a perfected electric action and by the rediscovery, in the mid 1960s, of tracker action. This movement was immediately promoted by some of the major Italian builders18 and it became stronger and stronger over the years. The neoclassical instrument was created, based on mechanical action and on the re-discovery of the traditional sounds and voicing techniques. But, as it is often the case, the intent was not that of copying the past but rather of preserving the best of tradition within a new context which was calling for a new use of the organ: the support of congregational singing.

One may get the impression that it is impossible to extract a general trend from this entire process of evolution. Still, I believe that one common denominator can be found: the unforced, pleasing singing quality that has survived unchanged for over five centuries, and which effectively represents, in musical form, the character of the Italian language.

                  2.              Concerning earlier use of the organ in western world churches, see Peter Williams (Duke University, Durham, NC) in his essay "The origin of the Christian organ with some particular reference to Italy," Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento," Ed. Carrara, Bergamo, 1999, p. 12. Referring to the early Middle Ages, he writes: "I don"t know any evidence that organs were brought into church in order to accompany singing--whether it was the celebrant singing at mass, the lay people responding with their own acclamations, or the monks chanting their daily office in private or in public. All that one can be certain about is that organs were there to provide sound, and whatever later music historians may have assumed, it is seldom if ever clear what kind of sound they made, or for what purpose and at what point they made it. Only from the thirteenth century onwards the picture is clear . . ."

                  3.              While the practice of congregational singing at celebrations in Italian churches may have had its first examples at the end of the nineteenth century, it was during the Second Vatican Council that this practice was actually encouraged.

                  4.              A Positivo can be described as a smaller size "cabinet" organ, self-contained, whose casework is normally divided in two sections: the lower case, containing the bellows (normally two multi-fold hinged bellows activated by levers), and the upper case, which sits on top and which holds the keyboard, the windchest and pipes. It was almost invariably built without independent pedal stops,  and its pedalboard, when present, consisted normally of one short octave, whose keys were connected to the corresponding keys of the first octave at the manual by means of strings or wires. Although easily movable (sometimes large handles on the sides of the two sections of the case indicate this possibility), it is different from a Portativo, an even smaller instrument whose primary function was that of providing music during outdoor processions.

                  5.              Larger instruments are not unknown to historical Italian organbuilding. I will mention two examples of rare complexity:

a.) The instrument at the church of San Nicolo L"Arena in Catania, by Donato del Piano (1698-1785), with a total of five keyboards, divided between three consoles attached to the case (1 manual - 3 manuals - 1 manual) with the larger console in the center and one pedalboard for the center console, plus a separate small automatic pipe instrument activated by a rotating drum. This enormous, beautiful instrument, now in a poor state of disrepair (among other things, the pipes have all been removed and stored), includes pipework of extremely unusual shape.

b.) The great organ at the Church of the Cavalieri di S. Stefano in Pisa, built between 1733 and 1738 by Azzolino Bernardino della Ciaia (1671-1755) with the help of other organbuilders from different parts of Italy, with four manuals plus a fifth manual activating a harpsichord. This organ was later converted into a pneumatic instrument and subsequently electrified. Only a portion of the original pipework survives.

                  6.              See Luigi Ferdinando Tagliavini, "Le risorse dell"organo Serassiano e il loro sfruttamento nella prassi organistica dell"epoca," in Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento", Ed. Carrara, Bergamo, 1999, pp. 80-84.

                  7.              See Giosue Berbenni, Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento," Ed. Carrara, Bergamo, 1999, pp. 22-24.

                  8.              The lower the wind pressure, the thinner the tongues must be to obtain promptness of speech. But thin tongues also produce undesirable side effects, notably:  a) A thinner timbre in general, with greater development of overtones and less fundamental; b) Uncontrollable sound at the bass register, where any reed naturally tends to become louder; c) Very weak trebles. To overcome these problems, a series of interesting methods were developed. I will mention a few:

a.) Wide and deep shallots to increase the volume of air excited by the tongue, with the effect of increasing the prominence of the fundamental in the tone;

b.) Double or even triple tongues at the low register, to control volume, timbre and stability;

c.) Variable tongue thickness at the treble, with the filing of the tip to obtain promptness while retaining a good volume of sound.

For a more complete description of voicing methods on low pressure reeds, with specific reference to the reeds of Serassi organs, see Francesco Ruffatti in "I registri ad ancia negli organi Serassi," Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento," Ed. Carrara, Bergamo, 1999 pp. 144-150.

                  9.              When the lowest pitched stop on the manual is the Principal 16' the nomenclature remains the same, although all stops start one octave lower in pitch. The stoplist becomes:

Principale (16')

Ottava (8')

Decimaquinta (4')

Decimanona (22/3')

and so on. In essence, the organ is still seen as based on the 8' Principal, with the extension of a counter octave towards the bass (see my article on Gaetano Callido, December, 1999 issue of The Diapason, p. 17, Note 8).

                  10.           Luigi Ferdinando Tagliavini in his article "Il ripieno," L"organo, Year 1, No. 2, July-December, 1960, Ed. Patron, Bologna, points out the difference between the Italian Ripieno and the northern European mixtures as follows:

"a) The classical Italian ripieno is divided into its constitutive elements, corresponding to separate stops, while the foreign mixtures, starting from a certain pitch (from 4', from 22/3', from 2', from 11/3' etc.) are condensed into one stop;

b) Both in the ripieno and in the northern mixtures a gradual "compression" towards the treble takes place, a compression which is more limited in the German and northern European organ, greater in the Italian organ. In fact a ripieno will have a "compressed" extension in the treble, reduced from 8' to 2', while in the Mixtur-Scharf scheme the treble is extended between 8' and 1';

c) The "masking" of the jumps produced by the breaks is done differently in Italy from abroad; in Italy, by the division of breaks into two different points, one for the octave stops and one for the quint stops; abroad by the partial or complete substitution of the break in quint and fourth with the one in octave.

The northern European mixtures, through a particular interpretation of the break and without any fear of going beyond the pitch limits in the bass and the treble as imposed by the Italian ripieno, tend to make the tonal "density" more uniform, by reducing the difference between the tonal richness of the bass and the treble. Part of such uniformity is sacrificed by the Italian organbuilder in favor of tonal beauty. This is why the use of the Italian ripieno is mostly chordal and for toccatas, while the northern European organum plenum, especially the German, can also perform a polyphonic role."

In c) Tagliavini refers to alternation of quint and unison breaks within the same rank in all ranks of the mixture.

The pitch limit of northern European mixtures and related stops is often C at 1/16', close to the limit of human hearing, one full octave higher than the Ripieno and this factor alone determines a dramatic difference in the sound from the Ripieno.

                  11.           Drawing is an acoustical phenomena by which the sound of a pipe is drawn or pulled into tune by the sound of a second pipe which is playing an interval close to being pure or in tune. This effect is stronger between unison pipes; when tuning the second pipe to the first, its sound will slide into tune as soon as its frequency approaches that of the first pipe, but before it actually reaches the same value, thus determining an apparent tuning condition. Adding a third pipe and trying to tune it to the two previous sounds becomes impossible if the first two pipes are in a status of apparent unison, because each of the two sounds will react to the third pipe differently, according to their real frequency value. The difficulties increase exponentially from note C#4 up in the example shown, where two groups of 4 and 3 equal size pipes respectively play at once. The procedure to tune the Ripieno is consequently different and definitely more complicated than that of a regular mixture stop, as it must take into account the drawing of equal length pipes.

                  12.           I am here mentioning two organs, built in Tuscany by the Paoli family of Campi Bisenzio at the beginning of the 19th century, both restored by Fratelli Ruffatti in recent years:

a.) the organ in the Church of S. Francesco in Pontassieve, near Florence, built by Giacobbe Paoli, which includes doublings at the Principale starting with note Bb3, at the Ottava from note F3 and at the Decimaquinta also from note F3;

b.) the organ built by Michelangelo Paoli in the Basilica of S. Maria, Impruneta - Firenze, utilizing the pipes of a previous instrument by Bernardo d"Argenta, 1535, which has doublings at the Principale starting from note F#3, at the Ottava from note B3 and at the Decimaquinta from C4. Having re-built the windchest entirely, the builder could have easily eliminated the doublings had he not believed in the validity of such tonal approach.

                  13.           As an example, Sicilian organs in the 18th century were often built with multiple Ripieno ranks activated by a single stop control.

                  14.           See "La riforma dell"Organo Italiano" by Baggiani, Picchi, Tarrini, Ed. Pacini, Ospedaletto (Pisa), 1990, pp. 9-10.

                  15.           The largest instrument built by the Serassi family, the "Organum maximum" with three keyboards and over three thousand pipes, was built in the romantic style as late as in 1882. This instrument was restored by Fratelli Ruffatti between 1983 and 1985. It includes many of the effects which were rejected by liturgists, such as the drum, a bell and other percussion.

                  16.           Ferdinando Casamorata (1807-1881), musician and music scholar, introduced the work of Cavaillé-Coll to the Italian musical scene by making public the work of J. A. De La Fage "Orgue de l"Église Royale de Saint Dénis, construit par MM Cavaillé-Coll père et fils, Facteur d"orgues du Roi." Rapport. II edition, Paris, 1846. See "La riforma dell"Organo Italiano" by Baggiani, Picchi, Tarrini, Ed. Pacini, Ospedaletto (Pisa), 1990, p. 12. He gave explanations and favorable comments on some of the most remarkable characteristics of the instrument, notably the variety of wind pressures, the Barker lever, the "strength" of the upper registers, especially the reed stops, etc., and presenting them as valuable innovations worth imitating.

                  17.           An important role in this process was played by George William Trice (1848-1920), a British merchant who became an organbuilder and established a factory in Italy. He built the first electric action organ in 1888 for the Church of S. Andrea, Genoa. Other notable instruments followed, among which the three-manual instrument for the Church of the Immaculate Conception in Genoa, inaugurated in 1890 with concerts by Alexander Guilmant and Filippo Capocci.

18.               

Tamburini and Ruffatti were the first major Italian companies, in the early 1960s, to resume building mechanical action instruments.

 

Francesco Ruffatti has been a partner since 1968 of Fratelli Ruffatti, builders and restorers of pipe organs, in Padova, Italy. Besides being the tonal director of the firm, he is actively involved in the research on historical Italian organs and the supervision of the many historical restorations performed by the firm.

J.H. & C.S. Odell, East Hampton, Connecticut, Opus 644

St. Ann’s Episcopal Church, Bridgehampton, New York

From the Rector of St. Ann’s

The committee all agreed--something had to be done. For
years the church organ had been in irreversible decline, and the time had come
to act. I regarded this to be a daunting and confusing challenge in which we
needed professional counsel. Dr. Mark Andersen guided us through the various
options and needs of the decision-making process, and by July 2004 it was
agreed that J.H. and C.S. Odell of East Hampton, Connecticut be engaged to
restore the organ. It was a decision that we would never regret.

In September 2004, Edward and Holly Odell arrived to remove
the existing organ. Pipes were carefully laid out in special boxes. Frames and
blowers were removed--and those were only the things that I could
identify! It all happened remarkably quickly, and before long the truck was
driven away leaving a large space where the console had once stood, and a
spotlessly clean church where the disassembly had taken place.

The novelty of using just piano and occasional other
instruments wore off after Christmas, and we waited anxiously for the organ to
return. Our patience was not helped by tantalizing photographs and reports sent
regularly from the Odell factory showing the new instrument taking shape!

It was March 2005 (the day I was flying off on vacation)
that the Odell team returned. It was time to put the whole thing together, but
it was only two weeks before Holy Week, and three to Easter. Could it really be
done?

Eight days later I returned to find the church in wonderful
disarray with parts and pipes everywhere, and Edward Odell looking and sounding
confident, if a little tired. Yes, of course it could be done. The project was
running according to schedule. The organ would be partly voiced by Palm Sunday
and ready for Easter.

Every part was in place and every promise fulfilled. A
magnificent new console was carefully maneuvered into position. Pipes were
ready and being expertly voiced by Holly Odell. Cables and wires were
connected. The organ had life--and was indeed ready for Easter morning. It
was resurrection in a different form!

We have not looked back since then. Not only has this
instrument enhanced our Sunday worship, it has enabled us to host a season of
superb organ recitals over the summer, and earned for St. Ann’s Church a
reputation for being a place where good music can be found.
style="mso-spacerun: yes"> 

Working with the Odell Organ Company has been not only a
proven right decision but also a joy. From the outset we not only admired the
professionalism of Edward and Holly Odell, but also came to share in their love
of organs and sheer depth of knowledge in their field. All these things,
coupled with their warmth and sense of humor, have made the whole process one
which we can reflect on with immense satisfaction. It is never an easy task for
a small parish church to embark on such a large project and investment, but we
know that we have learned and benefited so much from choosing the right organ
and the right builder.

From the Consultant

As an organ consultant for nearly 35 years, I have had the
opportunity to design a large range of instruments from the smallest two-manual
to several five-manual instruments throughout the United States, England, and
Australia.

St. Ann’s parish is that wonderful combination of
sophistication in a relaxed atmosphere. It is many New Yorkers’ church away
from home, and the organ would have to meet the discriminating tastes of
parishioners who worship in some of the largest churches in the metropolitan
area.

There was not much with which to start--an old hybrid
Möller from the ’20’s that was on its very last legs after having several ranks
replaced over the years. I designed an organ specification capable of
accompanying a proper Anglican service, but in a size and fit that matched St.
Ann’s. After requesting bids from many organbuilders, it was clear that J.H.
& C.S. Odell had the talent to see the task through with outstanding
results. Tonally the organ now fits the space perfectly and is complete enough
in specification to satisfy even the most discriminating organists. The
craftsmanship is superb, and the voicing is clear and clean, leaning beautifully
toward the English tradition. The project has surpassed my expectations.

From the Organbuilder

Our Opus 644 began life as what could be termed a “Heinz 57”
instrument, which is to say it featured a combination of pipes and parts from a
combination of organbuilders and suppliers. The console case and most of the
wooden pipes in the organ date from a five-stop 1927 M.P. Möller instrument,
which was then rebuilt and altered in the early 1970s. It was during this 1970s
rebuild that much of the original pipework was replaced.

As we found it, the organ was a unified instrument of modest
resources, most of them well made if not terribly well looked after. It was
unrefined, but met the basic requirements. In the 1980s a German supply house
Trumpet 8’ and Mixture III (inexplicably, a Zimbel based on 2?3’ pitch) were
added, along with a polished tin Gemshorn that was used to form a façade. The
entire organ was in a single expression chamber to the right of the chancel. The
existing electro-pneumatic unit chests, made from solid mahogany, were in good
physical condition, though the installation made maintenance access difficult
in certain areas.

In July of 2004, Dr. Mark Andersen (organ consultant to St.
Ann’s) approached us with a prospectus that included a rebuild and enlargement
of the organ. In addition to new pipes and new chest work, a new 3-manual
terrace-jamb console was part of this plan.

Dr. Andersen’s proposed stoplist would add a total of nine
ranks to the organ. The scheme had an immediate appeal, as it would expand the
resources of the organ to include a full principal chorus in the Great, as well
as a new 8’ Rohrflute to contrast the existing Chimney Flute in the Swell.
“Fleshing out” the Great with six new ranks allowed us to recast the remaining
resources to work as a mostly independent Swell division. The new scheme would
also extend the existing Trumpet to 16’ pitch to play from the Pedal and add a
small Cornet (a tenor C, 2-rank 12/17 combination, scaled and voiced to match
the new Great flute).

The challenge, of course, was to now somehow fit 19 ranks in
a space that before barely contained eight. Early in the design process it became
evident that much of the precious real estate in the organ chamber could be
reclaimed if the many offset chests for various ranks could be consolidated
onto a new single offset chest that would also provide for the new Trumpet 16’.
We also wanted to ensure the new chamber layout would permit adequate access
for service and, most importantly, tuning. Rebuilding the existing expression
shades and fitting them with new expression controllers made available space
that had been previously occupied by a pneumatic motor with an unwieldy linkage
system.

We developed a new 7’4? diatonic chest scale to accommodate
the new stops and the relocated Gemshorn. The existing Principal 8’ was
carefully revoiced to give it more moderate power, and the new principal ranks
were scaled and voiced to build from this new foundation. The new Great Bourdon
8’ was voiced using a special arch cutup schedule, which lent the pipes a color
that allows the stop to work superbly as both a solo and ensemble voice. The
Swell was given its own new 3-rank mixture based on 2’ pitch, and the existing
Zimbel mixture was recomposed into a more appropriate chorus mixture based on
11?3’ pitch for the Great.

Though the action for the new chestwork was specified to be
electro-mechanical, we milled all windchest toeboards to be no less than one
and one-half inches in thickness. This, along with proper attention to voicing,
successfully offset any pipe speech problems normally anticipated with this
type of action. Our windchests were made from solid poplar, with the exception
of the toeboard for the new Swell Mixture, which was milled from sugar pine.

The new console and case, both entirely of our own design
and manufacture, were milled  in
our East Hampton shop from solid quarter-sawn white oak, and stained and
finished to match existing fixtures in the sanctuary. The console interior
(stop jambs and key cheeks) was milled from solid walnut and finished with
hand-rubbed Danish oil. The façade pipes are polished tin, made to custom
specifications we developed and submitted to our friends at Giesecke. The new
flue pipes were built to our scales by Luc Ladurantaye Tuyatier of Lac Saguay,
Quebec.

Along with the standard complement of accessories, the
console features an integrated control system with multiple memory levels,
programmable crescendo and sforzando, 12-step transposer and MIDI interface for
record and playback ability. The digital Antiphonal division was contracted and
installed separately by Artisan Instruments.

The Church of Our Lady of Loretto, Cold Spring, New York

This historic church, known for its remarkable collection of
stained glass windows, was recently restored, with a new instrument and a
marble chancel floor included in the renewal plans. Under the direction of Fr.
Brian McSweeney, Pastor; Frances Pergamo, Director of Music; and Fr. Richard D.
Baker of the New York Archdiocese, three organbuilders were each invited to
present their vision of an appropriate musical instrument. The smallest and
most stylistically focused proposal submitted, the new Glück organ occupies a
traditional position in the rear gallery to great acoustical advantage. While
the organ looks toward the French orgue d’accompagnement of the 1860s for both
its concept and tonal palette, it is certainly not intended to be a stylistic
copy.

The manual soundboards are placed side-by-side at impost
level, with the Swell to the right, its vertical shutters operated by direct
mechanical linkage. The two large wooden pedal stops stand on their own
windchests behind the organ. The Great organ incorporates some pipework from a
mid-1870s Levi Underwood Stuart organ of undetermined provenance. Interior
metal pipes are of 70% lead alloy, except for the Swell strings, which are of
50% tin. Wooden pipework is of pine and fir. The façade pipes are built with
English bay leaf mouths arrayed in a swag pattern after Gottfried Silbermann’s
façades of the 1740s.

The walnut keydesk en fenêtre sports beveled figured maple
jambs and pao ferro drawknobs. Both pedal and manual accidentals are Brazilian
rosewood. Compasses are 56/30; there is no combination action, but the three
unison couplers are reversible by toe paddles. The case is painted in various
shades of olive, with details in sapphire, ruby, and faux marbre. Architectural
design was by Sebastian M. Glück, who executed the Neapolitan-style angel,
tower finials, and buttress niches, which are suitably polychromed and gilded.
Color photographs may be viewed at the firm’s web site at
<www.glucknewyork.com&gt;.

The structural design and layout are the work of Albert
Jensen-Moulton, general manager of the firm, who was assisted in the
construction of the organ by Dominic Inferrera, foreman. Voicing and tonal
finishing were accomplished on site by Sebastian M. Glück, tonal director. The
organ was formally dedicated in a series of three recitals by Lana Kollath, Dr.
Jennifer Pascual, and the builder.

About the organ.

Designing an organ for Rieth Hall at Goshen College was a
pleasure. The opportunity to place the organ in the traditional location, high
in the rear gallery, was ideal both visually and aurally. The form and
proportions of the hall, with its austere yet warm and inviting interior,
called the organbuilder to respond with similar clarity and restraint. The
ample height of the room suggested a plain, vertical configuration of the
instrument, on which natural light from the clerestory windows would fall
gently. Everything about the hall spoke of its solid construction and honesty
of materials, qualities that we strive to reflect in our organs. Likewise the
acoustical properties of the hall, so warm and reverberant and at the same time
intimate and clear, allowed the organ’s tone to develop freely without
being forced. The result is an endearing musical instrument that is
aesthetically inseparable from the space in which it stands.

Initial inspiration for the Goshen case came from the organ
built by David Tannenberg in 1774 for Trinity Lutheran Church in Lancaster,
Pennsylvania. While only the case and façade pipes of that lovely
instrument have survived, they constitute the finest example we have in our
country of south German case architecture from the 18th century.
Tannenberg’s use of the double impost, with its Oberwerk division
gracefully placed as a reflection of the Hauptwerk below, was typical of organs
in his native Saxony and Thuringia. Other exterior influences from that time
and place include the two swags that bracket the center tower, and the broad
lower case that supports the full width of the impost and omits the spandrels
common to earlier styles. Apart from its simple springboard moldings, the
Goshen case is relatively flat and plain by comparison with its historical
counterparts. Its only bold three-dimensional element is the polygonal center
tower. The small pointed towers in Tannenberg’s design are here merely
implied by the V-shaped arrangement of foot lengths in the tenor fields. The
use of six auxiliary panels to raise the smaller pipe feet above the impost
moldings adds interest to the design. The considerable height of the lower case
was determined by the need for a passageway over the 2-foot concrete riser
behind the organ. This height gave space between the console and impost for the
eventual inclusion of a small Brustwerk with several stops for continuo
accompaniment. Cabinets for music storage are built into the back on both sides
of the lower case.

Another aspect of the design reminiscent of 18th-century
south German traditions is the position of the windchests in relation to the
action. The two windchests of the Hauptwerk are spaced apart from the center of
the case by the width of the keyboards. This leaves room for trackers of the
Oberwerk to reach their rollerboard without blocking access to the Hauptwerk
action and its pallets. It also provides optimum space for 8’ bass pipes
at the sides and leaves room for tuning the tenor pipes of the Hauptwerk with
only minimal obstruction by the Oberwerk rollerboard. The windchests for the
Pedal are located behind the case at the level of the impost, a placement that
Tannenberg could also have used.

Both the playing action and stop action are mechanical. The
manual keys are hinged at the tail and suspended from their trackers. There are
no thumper rails to hold the keys down, so they are free to overshoot slightly
when released, as is the case in traditional suspended actions. Trackers,
squares and rollers are all made of wood. There is no felt in the action. Keys
are guided by pins at the sides. Together these details combine to give a
feeling of buoyancy and liveliness reminiscent of antique instruments. The aim
is not so much to provide a light action as to arrive at one having the mass
and friction appropriate to the size and character of the organ. Such an action
may need occasional minor adjustment of key levels with changes in humidity,
but this is a small price to pay for the advantages gained over more sterile
modern alternatives. 

Wind is supplied by two single-fold wedge bellows (3’ x
6’) fed by a blower located in a small room below the organ. Natural
fluctuations of the wind pressure in response to the playing contribute to the
lively, singing quality of the organ’s sound. A wind stabilizer can be
engaged when unusually heavy demands on the wind system call for damping of
these fluctuations. The organ’s single tremulant is made in the old-fashioned
beater form. On seeing a tremulant puffing away in one of our organs, a
Japanese friend remarked that the organ was laughing! It is useful to think of
an organ’s wind as its breath and the bellows as lungs, for the
instrument’s appeal is closely tied to our perception of its lifelike
qualities. 

The tonal character of an organ is rarely revealed by its
stoplist. This is particularly true in an instrument of only twenty-four stops.
Once the builder accepts the constraints of a given style and the essential
registers have been chosen, there is usually little room or money left to
include stops that would make a modest design appear unique on paper.
Fortunately for the art, the musicality of the organ is not bound by its
stoplist; rather, it is determined by a host of other complex factors. These
can be partially defined in the technical data of pipe scaling and
construction, general design parameters, materials and the like, but in reality
much more rests on the elusive criteria of experience, skill and taste of the
builder. Taken together this means that each new organ, albeit small, presents
fresh opportunities for artistic expression. It is important that all the pipes
speak promptly, be they reeds or flues, except in the case of strings, which
gain charm from their halting speech. It is less important that the pipes
produce precisely the same vowel sounds from note to note, for here variety
adds refreshing character and interest to the organ.

At Goshen we chose to voice the 8’ Principal to be
somewhat brighter and richer in overtones than has been our wont. This was
achieved by giving the pipes lower cutups than was customary in German and
Dutch organs of the 17th century and before. The five distinctly different
8’ flue stops on the manuals deserve special mention. Although all
followed scaling patterns we have used frequently in the past, when voiced they
proved to be unusually satisfying, particularly in combination with each other.
Whenever the 16’ Bordun is used with them a magical new dimension is added
to the sound. If, for example, one draws the Bordun with the Viol da Gamba, the
effect is that of a quiet 16’ Principal. Used with the Spillpfeife the
Bordun reverts to its role as a flute. In an organ of this size it is crucial
that every stop work as well as possible with every other. Following south
German practice, both 8’ and 4’ flutes on the Hauptwerk are made in
the same form. This duplication of flutes within the same family was not the
custom in the north, where lower pitched flutes were usually stopped and those
above them progressively more open. The Oberwerk configuration at Goshen with
its two stopped 8’ registers and partially open 4’ Rohrflöte is
typical of the northern tradition. We look forward to the day that the 16’
Violonbass with its cello-like speech can be added to the Pedal.
style="mso-spacerun: yes"> 

The distinctive musical effect of the Goshen organ is
strongly colored by the use of the recently released Bach-Lehman temperament
described in the accompanying article. Because the completion of the organ in
February coincided with the publication in Early Music of Bradley
Lehman’s treatise on J. S. Bach’s temperament, we chose to tune the
organ according to his plan. Here was the ideal opportunity to try the
temperament on an organ built in Germanic style and at the same time to honor
Dr. Lehman as a distinguished Goshen alumnus for his work in this field. The
experiment has been a fascinating one. It has provided a place to hear
Bach’s organ music as we have not heard it before. We are honored to have
played a part in translating the dry mathematical numbers of this temperament
into the vibrant sound of the organ. 

With few exceptions the many parts of the organ were
constructed from raw materials in our Virginia workshop. Through the skills of
each craftsman the design moved from an idea to paper and then through raw wood
and metal into a large and impressive object. Note by note the tonal picture
has been filled in by voicing and tuning until in the end we experience a new
instrument with an identity all its own. We hope that it will give pleasure to
those who play and hear it far into the future.

The organ project at Goshen College

“Dienlich, Ordentlich, Schicklich, Dauerlich”

In 1999 we were asked by the organ consultant for Goshen
College, Roseann Penner Kaufman, to make a proposal for the new Goshen College
Music Center. As with any new project, I went to Goshen full of excitement at
the promise of participating in what was to be a spectacular project. My
enthusiasm was short-lived when I saw the design for the recital hall. It was a
standard fan-shaped, sloped-floor, small college recital hall, with theatre
seats and carpet in the aisles. The space for the organ was planned in a niche
at the back of the stage. The design would have been fine for small chamber
recitals, but it was not a proper home for an organ. The prospects for the
organ looked bleak. We would not have felt productive or inspired. We always
say that the room is more than half the organ. I took a deep breath and told
the Goshen committee what I thought of the plan. The committee listened and
asked us to offer suggestions on how the recital hall might be designed to work
best with the musical programs envisioned for this space.

I returned to Staunton eager to develop a plan. One of the
first things I did was to research the Mennonite Quarterly Review for articles
describing historical Anabaptist worship spaces. I hoped that the essence of
these rooms would lead me to an aesthetic that would tie the new hall to the
old tradition, which would, in turn, also be good for music, especially the
organ. My research acquainted me with four German words used to express the
qualities of the historical spaces: dienlich, ordentlich, schicklich and
dauerlich--serviceable, orderly, fitting and lasting. I also found prints
of the interiors of some of these churches. Rectangular in shape with open
truss timber roof framing, clear glass windows, galleries on several sides,
rough stone floors, moveable chairs, unadorned, honest and powerful, these
spaces had all the qualities that I was looking for. They also had enduring
musical-acoustical qualities and so many are used today for concerts.

The simple sketch that I made went first to the Goshen organ
committee who, led by Doyle Preheim and Chris Thogersen, embraced the plan.
Then the concept went to Rick Talaske and his team of acousticians. They
transformed the plan into practical geometry and surface treatments to make the
space an acoustical success. Mathes Brierre Architects took the acoustical plan
and translated it into a visual design that evokes the warehouse or
brewery-turned-church concept of the early Dutch Mennonite spaces. Schmidt
Associates worked through the technical details with Casteel Construction to
conceive the simple pre-cast concrete panels and graceful curved steel arches
that make the hall appealing in its architecture, superior in acoustical
performance and straightforward and durable in construction. There was creative
and sensitive work done by a Goshen group concerned with decor and furnishings.
The result is successful beyond our expectations. The collaboration of all the
partners made the project exceed the ability of any one of us.

Once the hall was underway, we scheduled a meeting at St.
Thomas Fifth Avenue in New York with a group from Goshen and Calvin and Janet
High from Lancaster, Pennsylvania. We had a great day in New York showing
everyone our organ in the gallery of St. Thomas. The Highs’ enthusiasm
for the St. Thomas organ and the Goshen Music Center paved the way for their
generous gift that underwrote the cost of the organ.

We realized that the floor area of Rieth Hall was small in
relation to the height. We saw that if there could be the addition of one more
bay to the length there would be significant improvement in the proportions of
the space and at least 50 more seats could be added. Again, the Goshen design
group supported our suggestion. At a time in the project when the building
committee was attempting to control costs and squeeze performance out of every
dime, they found the funds for this most important late addition.
style="mso-spacerun: yes"> 

I predicted at the time we were creating the designs for
Rieth Hall, that the unique qualities of this space would have something to say
to the Goshen students about music and worship. This prediction has been
realized. First, there is genuine enthusiasm for a cappella singing in Rieth
Hall, encouraging this wonderful Mennonite tradition. Second, there has been a
spontaneous seizing of the space by the students for their own student-directed
Sunday worship. In this age of searching for the right path in worship and
liturgy, of debating the influence and appropriateness of mass media and
popular music for worship, we have built something at Goshen College that
reaches across the span of time to those Mennonite roots. Led by the seemingly
old-fashioned qualities of dienlich, ordentlich, schicklich and dauerlich, we
have made a  music space and organ
that inspire and excite us to make music and to celebrate and serve our God and
Creator.

Wood and the Goshen organ

The traditional pipe organ is a wooden machine. Early on in
our careers as organ builders we realized that getting control over our
materials in both an aesthetic and technical sense was essential to our success
as organ makers. Our first path was to make friends with our neighborhood
sawmillers. One of these was an octogenarian whose experience reached back to
horse logging and steam power. He taught us the value of long, slow, air-drying
of lumber. He also knew the old traditions of sawing, how to take the tension
out of a log, how to saw through the middle of the log and keep the boards in
order so that the cabinetmaker could match the grain. He remembered the methods
of quarter sawing that impart the most dimensional stability to the boards and
in oak bring out the beautiful fleck of the medullary rays. We have built our
own sawmill based on a portable band saw. For quarter sawing, we have built a
double-ended chain saw that can split logs up to 60 inches in diameter. The
half logs (or quarters in extremely large timber) are then aligned on our band
saw and sawn in a radial fashion into boards. This lumber is then air-dried for
a number of years. At the end, we put the wood in our dry kiln and gently warm
it up to stabilize the moisture content at 8% to 10%.

Oak is the traditional wood of Northern European organ
building so it was natural for us to choose white oak for the Goshen organ. We
have long admired the Dutch and German organs dating back to the 16th century.
The earliest organs show only the natural patina of age and no finish; the
concept of finishing wood as in varnishing or oiling came well into the 18th
century. We followed this earlier practice for the Goshen organ. The oak has
been hand-planed to a smooth polish, much smoother than can ordinarily be
produced with sanding. The hand-planed wood will resist dirt. We feel there are
also musical benefits from using wood in its natural state. The case and
carvings together with all the interior parts transmit sound energy and reflect
and focus the sound of the pipes. Also, the open pores and surface
imperfections of the natural wood have an effect on the sound reflection.

Another aspect of wood use in historic organs is how
efficiently the old builders utilized their wood. Before the age of machinery,
cutting, transporting and converting timber to sawn, dried lumber ready for use
was costly. The best wood was always used for the keyboards, playing action,
wind chests and pipes. The next selection went to the most visible parts of the
case, especially the front of the organ. The rest was used for carvings, heavy
structural members, walkways, bellows framework and back panels. Some of this
wood shows knots, cracks and other defects that might offend our modern sense
of perfection. However, in addition to demonstrating good wood utilization, the
varying density and differences in surface texture of these so-called defects
may indeed benefit the music. How we perceive the sound of an organ is a very
complex and subtle equation. This is one of the wonderful aspects of the real
pipe organ that differentiates it from the sterile sound of the electronic
substitute. We feel it is good stewardship to apply the hierarchy of selection
as practiced by the old masters. We try to use all the wood, through careful
selection, with thoughtful conservation of a vanishing resource.

--John Boody

Acoustic design of Rieth Recital Hall at Goshen College

In 1998, the design team of design architect Mathes Group
(now Mathes Brierre Architects), architect of record Schmidt Associates and
acoustician The Talaske Group (now Talaske) began preliminary work on a new
music education and performance building for Goshen College’s campus.
This project was the College’s greatest building investment to date and
they were determined to do things right . . . with a very modest budget. The
Recital Hall (now Rieth Recital Hall) was slated to house a new tracker organ
of exceptional quality. As acousticians, we offered some general planning
recommendations--not the least of which was a 50-foot ceiling
height--and recommended that the organ builder be hired as soon as
possible.

Enter John Boody of Taylor & Boody, organ builders from
Virginia. John energized the subsequent meetings with some profound advice that
proved to set the final direction for the space. He moved our thinking from a
“fixed” seating configuration to a flexible arrangement based on a
flat floor where seats can face either end of the room. This unique concept
facilitated the accommodation of a conventional “recital hall” or
assembly arrangement with musicians or presenters on a small stage. The cleverness
of the concept is the seats can be turned to face the opposite direction in the
room, offering a classic organ recital arrangement. Furthermore, John
recommended that the proportions of the room would be better served if
lengthened by adding another bay of structure. These fundamental planning ideas
changed the direction of the design in perpetuity.

We embraced these new directions yes">  and identified the many other room acoustics design features
that would support the client’s needs. The 50-foot ceiling height remained,
and we worked with the architects and construction manager to render the room
as a sound-reflective concrete enclosure, embellished with wood. The goal was
to maintain the warmth of sound created by the organ. Within the “theatre
planning” process, we guided and exploited naturally occurring
opportunities for introducing sound diffusing shaping to reflect low- and
mid-pitched sound in all directions--by introducing one side balcony and a
rear balcony, recesses from circulation paths and recesses created by
deeply-set windows. We recommended deliberate articulation of the walls to
diffuse mid- and high-pitched sound. Wood surfaces were detailed to minimize
absorption of low-pitched sound. Retractable velour curtains and banners were
recommended in abundance and specified by Bob Davis, theatre consultant.
Architecturally, curtain and banner pockets were created so the sound-absorbing
materials could be retracted completely on demand. These features make possible
a broad “swing” of the sound of the room from very reverberant for
choral and organ performance to articulate for assembly events or amplified
music performance. Fundamental to the acoustic design was the need for silence.
This was accomplished by structural discontinuities in the building (acoustic
isolation joints) and the proper placement and design of heating and air
conditioning systems.

Within their mission statement, Goshen College states:
“Musical expression is a human manifestation of the divine impulse and,
as such, serves as a window into the individual soul, a bridge between human
beings and a means of corporate religious experience.” In light of the
students adopting the Rieth Recital Hall for their weekly convocations and the
many other uses, we are pleased to say the happy story continues!

Bach temperament

This organ is the first since the 18th century to use Johann
Sebastian Bach’s tuning, as notated by him in 1722 on the title page of
the Well-Tempered Clavier. This tuning method is a 2004 discovery by Bradley
Lehman. The article about this discovery is published in the February and May
2005 issues of Early Music (Oxford University Press), and further details are
at <www.larips.com&gt;.

The layout, dividing the Pythagorean comma, is:

F-C-G-D-A-E = 1/6 comma narrow 5ths;

E-B-F#-C# = pure 5ths;

C#-G#-D#-A# = 1/12 comma narrow 5ths;

A#-F = a residual wide 1/12 comma 5th.

In this tuning, every major scale and minor scale sounds
different from every other, due to the subtle differences of size among the
tones and semitones. This allows music to project a different mood or character
in each melodic and harmonic context, with a pleasing range of expressive
variety as it goes along. It builds drama into musical modulations.
style="mso-spacerun: yes"> 

The result sounds almost like equal temperament, and it similarly
allows all keys to be used without problem, but it has much more personality
and color. In scales and triads it sounds plain and gentle around C major (most
like regular 1/6 comma temperament), mellower and warmer in the flat keys such
as A-flat major (most like equal temperament), and especially bright and
exciting in the sharp keys around E major (like Pythagorean tuning, with pure
fifths). Everything is smoothly blended from these three competing systems,
emerging with an emphasis on melodic suavity.

The following chart shows the relative size of each major
third, resulting from each series of the intervening four fifths. This system
of analysis is from the 1770s, published in the theoretical work of G. A. Sorge
who was a former colleague of Bach’s. The intervals having higher numbers
sound spicier, more restless. In this measurement, a value of 11 would indicate
a major third that is one syntonic comma too sharp (a “Pythagorean major
third,” having been generated by four pure fifths).
style="mso-spacerun: yes">  A pure major third would be represented
here as 0.

   9

Equal temperament, as opposed to the variety shown here, has
a constant size of 7 in all twelve of the major thirds.

In functional harmony, the Bach tuning sets up especially
interesting contrasts within minor-key music. The key of A minor has the
plainest tonic juxtaposed with the most restless dominant. F minor, a major
third away, has the opposite relationship: troubled tonic, calm dominant. And
C# minor has the average character between these behaviors, where the tonic and
dominant are both moderately energetic. 

In major-key music, the tonics and dominants have characters
similar to one another. The sizes of major thirds change by only 1, 2, or 3
units from each key to its neighbors, moving by the circle of fifths (through
typical subdominant/tonic/dominant progressions). Any change of Affekt is
therefore gradual and subtle, as if we never really leave the home key
altogether but it feels a little more or less tense as we go along.

In any music that modulates more quickly by bypassing such a
normal circle-of-fifths cycle, the contrasts are momentarily startling. That
is, the music’s dramatic harmonic gestures become immediately noticeable,
where the major thirds have changed size suddenly from one harmony to the next.
This comes up for example in the Fantasia in G Minor (BWV 542), Gelobet seist
du, Jesu Christ (BWV 722), and the fourth Duetto (BWV 805), and especially in
music by the Bach sons.

This system turns out to be an excellent tuning solution to
play all music, both before and after Bach’s. It is moderate enough for
complete enharmonic freedom, but also unequal enough to sound directional and
exciting in the tensions and resolutions of tonal music.

A recording will be ready for release this summer, including
music by Bach, Fischer, Brahms, et al.

A brief history of the organ in the Mennonite Church

Some people might find it unusual to find such a remarkable
organ in a Mennonite college. Aren’t the Mennonites those folks with the
buggies and suspenders? It is true that some Mennonite congregations still take
literally founder Menno Simons’ caution against the organ as a
“worldly” invention, but most, especially in the last fifty years,
have embraced it as a vital contributor to the musical and worship life of the
community. 

The Mennonite Church has its beginnings in the 16th-century
Protestant Reformation. Because of persecution, most of the early worship
services were held secretly, in homes or out-of-the-way places. Mennonites also
believed that the true church existed in small, simple gatherings; therefore,
it was uncommon for early Mennonites to even set aside a separate building for
worship. 

Two hundred years after the beginning of the movement,
churches in Germany and the Netherlands had grown to the point of meeting in
dedicated buildings, and by the 1760s several in urban areas had installed pipe
organs. It was another two hundred years, however, before organs became common
in the Mennonite conference that supported Goshen College. Even now, the organ
is not necessarily assumed to support congregational singing, but contributes
other service music. Organ study is now offered at all of the Mennonite Church
USA-affiliated colleges, and the new Taylor & Boody organ at Goshen will
certainly have a profound impact on the future of worship and organ study
throughout the denomination.

Bradley Rule

Bradley Rule received a Bachelor of Arts in Organ Performance from the University of Tennessee, from which he graduated with high honors in 1982. From 1982 to 1988 he worked for the Andover Organ Company in Lawrence, Massachusetts, and at this firm he encountered hundreds of different kinds of mechanical-action organs.
After working nearly six years at Andover Organ Co., Mr. Rule returned to his home of East Tennessee and began business for himself. He set up shop in the old St. Luke Presbyterian Church building in New Market, Tennessee, a venerable old brick building which has served admirably as an organ building shop. Mr. Rule has built and restored organs from Alabama to Massachusetts in the years since 1988.
In addition to his lifelong pursuit of organbuilding, Bradley Rule has held various positions as organist or organist/director from 1976 until 1991, at which point his organbuilding business began to demand his undivided attention. During these years, his organist activities included playing concerts and making recordings, in addition to the usual weekly church duties.

While completing the installation of a new organ in the
Tennessee Valley Unitarian Universalist Church in late 1998, I was drawn into a
conversation between Will Dunklin, the organist, and Marian Moffett, a viol da
gamba player who is a member of a local early music ensemble. Marian indicated
an interest in acquiring a small chamber organ for her home, which would be
appropriate as a continuo instrument for early (particularly English) music.
After briefly discussing prices, both Will and myself commented that an early
American organ (pre-1860) would possess many of the tonal characteristics
required for such a use, as well as providing its own historical interest.
Besides, restoration of such an instrument would likely be quite economical
compared to the price of a new organ.

After checking with the Organ Clearing House, we found
nothing small enough for such a use, and the matter got shelved in the back of
my mind. About a year later, I received a message from Marian that Will had
found a small American chamber organ on eBay, for sale by a doctor in Michigan.
After some negotiation, she purchased the organ and went with Will in a rented
van, returning two days later with said instrument. In such a serendipitous
series of events, then, did this enigmatic and charming little instrument fall
into my hands for the purpose of restoration.

Provenance

Establishing the provenance of the instrument was the first
item of interest; since the organ sat in the shop for a year before work could
commence, it gave me some time to pursue the subject. Alas, despite our efforts,
the little instrument still remains anonymous. The following, however, are some
of the identifying characteristics pertinent to its provenance.

The cabinet holds a number of clues, which help us make some
general conclusions. The cabinet (as well as the chest and internal framework)
is made of eastern white pine, with a smattering of cherry and black walnut.
This clearly identifies it as an American-made instrument. The Empire case,
with its ubiquitous crotch mahogany veneer and late Empire styling, seems to
place it between about 1845-1855. According to Barbara Owen, the cabinet looks
like the work of early Connecticut builders. This dovetails nicely with the
oral history we received from the previous owner, who had been told that the
organ was built for the Lockwood family of Norwalk, Connecticut. Apart from
these general observations, the cabinet holds another clue: the ripple
moldings, which appear in several shapes and sizes. According to an article by
Carlyle Lynch in the magazine Fine Woodworking (May/June 1986, pp. 62-64), such
molding was made by only one company in America, the Jonathan Clark Brown clock
company in Bristol, Connecticut. This company made the gew gaw covered clocks
known as steeple clocks, but after the factory burned in 1853, J. C. Brown
clocks no longer were made with the unique ripple moldings. Such moldings
require an elaborate, slow-moving machine for their manufacture, and the
machine was evidently never rebuilt. If the builder purchased his ripple
moldings from the clock company, then it is clear the instrument was built
before 1853.

The hardware found on and in the instrument provides more
tantalizing hints as to the organ's provenance. The mix of early factory-made
components with other hardware which is clearly hand-made seems to place the
organ on the very cusp of the Industrial Revolution. For instance, the lock for
the keydesk lid bears unmistakable marks of being handmade: all parts were hand
filed out of solid brass, and then fitted together with hand-threaded screws. Yet,
the hinges which occur in various places (e.g., swell pedal, main reservoir)
are all of cast iron and bear the name "Clark's Patent." While a bit
crude (they certainly are not interchangeable), they bear all the signs of
early factory production. An additional item of interest is that one leaf of
each hinge was cast around the pin while the pin was inserted into the other
leaf. This makes it impossible for the pin to ever work its way out; it also
makes it impossible to separate one leaf from the other, short of a sledge
hammer.

The most interesting piece of hardware is the square iron
roller for the swell mechanism. Clearly stamped on the bar is the word CLYDACH.
It turns out that Clydach was a Welsh ironworks established in 1793, continuing
in production until about 1858. I'm not sure what this reveals about early
American sources of iron and steel. Of course, it is possible that the builder
recycled the piece of iron from an older apparatus or structure.

Finally, even the humble wood screws give us some
information. They are a mix of the earlier blunt ended screws and the more
modern pointed screws, and all but one or two were clearly made by a machine.
This also seems to point to about 1850-1855, although I am unsure when the more
modern pointed wood screws became available. The E. & G.G. Hook organ of
1847 in Sandwich, Massachusetts, was put together entirely with blunt ended
machine-made screws, so it seems that modern wood screws came along a few years
later.

One intriguing note is written (sometimes scrawled) on
almost every piece of the instrument. The message "No. 2" can be
found on the bellows, keyboard, backboard, knee panel, etc. The inescapable
conclusion is that there must be (or must once have been) a "No. 1"
lurking out there somewhere, waiting to be discovered.

The reader is left to draw his own conclusions about the
provenance of the instrument. Clearly, the Empire style and the handmade
hardware place the instrument no later than about 1855. The wood screws fit
into the time frame of about 1850. The oral history as well as the general
design of the case place the builder in Connecticut. We were unable to find
information about "Clark's Patent" hinges, and CLYDACH presents more
an enigma than it does an answer. Perhaps a reader will recognize one of these
items and shed a bit more light on the history of this little instrument.

Restoration techniques

The following describes the techniques and materials used
for the restoration. An astute reader will occasionally see the tension which occurs
when the desire to restore the organ to its original state is not always in the
best interest of the customer. Ultimately, we did almost nothing to the
instrument which could not be easily reversed later. Additionally, we took
great care to avoid removing any original material (no pipe tops were trimmed,
and even the finish was not entirely removed).

Cabinet

Failing joints were disassembled when practical and re-glued
with hot hide glue. Other joints were simply injected with hot hide glue and
clamped for 24 hours minimum.

The reservoir and feeder assembly share a common 1"
thick horizontal board which is dadoed into the sides of the carcass. This
board was originally glued into the dados and glued and nailed to the front
rail directly above the two pedals (the self-closing swell pedal on the left,
and the single pumping pedal on the right). Mahogany crotch veneer was then
applied over the nails. Someone had previously done a very nice job of sawing
through the nails and sliding the entire assembly out the back of the
instrument in order to patch the bellows. We decided to leave this alteration,
since it is truly the only way to access the bellows for releathering. Maple
cleats were added so that the 1" board could be screwed securely to the sides
of the carcass.

Stabilizing and repairing the veneer became one of the most
time-consuming jobs. Like many Empire pieces, the crotch burl mahogany seemed
to shed little bits of veneer onto the floor every time one walked past. About
half of the veneer was no longer securely glued to the white pine below, and
the ogee-shaped front board of the folding lid was missing about 70% of its
veneer. The ogee crown molding veneer was almost entirely unglued from its
substrate, although miraculously most of the veneer was still there. The
decision was made to remove the remaining tatters of veneer from the ogee
shaped lid front and use the bits to patch veneer on the rest of the piece. The
lid front was then entirely re-veneered with book-matched mahogany crotch burl.

The crown molding presented another challenge; the veneer
was so brittle that even the slightest attempt to lift it in order to work glue
under it caused it to shatter. Clamping was difficult; since the veneer was
glued over a hand-planed ogee, the shape of the contour changed from one end to
the other, and the molding on the sides of the crown were quite different in
shape from each other and from the front. This precluded any possibility of
making precise blocks to fit the shape of the molding. The solution was finally
to inject fish glue through tiny holes in the veneer and clamp a sand-filled
Ziplock bag firmly over the area. The sand conformed perfectly to the contour
of the molding and distributed the clamping pressure evenly. The fish glue,
being a protein-based glue, was compatible with the old hot glue and adhered
well, though it required long clamping times of about 48 hours. Close
inspection reveals the pinpoint size holes through which the glue was injected,
but it seemed the least destructive way to stabilize and re-glue the very
brittle veneer.

Conservation of the finish required a careful approach.
Rather than subject the piece to the humiliation of being entirely stripped and
refinished, we decided instead to conserve what was left of the old shellac
finish. Parts of the case, such as the underside of the lid, retained the
original finish in excellent condition. Other parts had obviously been covered
with an additional layer of low quality shellac. Besides this, someone had
studiously "patched" every missing veneer chip by the application of
red-primer colored latex paint. Paint ended up on the surrounding intact veneer
as much as it did on the offending gap in the veneer. To address these multiple
problems, the course of action was as follows:

The top layer of accreted dirt and crazed finish was sanded
off using 400-grit sandpaper with paint thinner as a lubricant. This required
removing only a very thin film of finish. Then, a pad of wool and cheesecloth
was filled with shellac and applied over the remaining old shellac. This
smoothed out any remaining "alligatored" shellac. This French Polish
technique was repeated about a dozen times until the surface took on an evenly
covered appearance and began to glow. Then, at the request of the customer, the
shellac was sanded lightly and was covered with two coats of high quality
varnish for durability. On parts of the cabinet where extensive veneer patching
was required (such as the crown molding), the resulting surface was too rough
and the old finish too compromised for conservation; it was necessary to sand
the entire surface down to the bare wood. Then, colored pumice was rubbed into
the grain along with residual sanding dust and garnet shellac, after which the
usual french polish technique was used, followed by the two coats of varnish.
The orange colored garnet-lac returned the "old" color to the newly
sanded wood, making a perfect match. The results were visually stunning; the
mahogany crotch burl fairly leaps off the surface of the piece with three-dimensional
fervor. The keydesk itself is veneered with rosewood, and since the lid
evidently was always closed, the finish on the rosewood required little
attention.

The center panel of cloth was originally a very thin silk,
bright turquoise in color. We found well-preserved pieces of it under the wood
half-dummy façade pipes. Marian decided the original color was
remarkably wrong for her house (I had to agree), and chose a silk of subdued
gold instead. The turquoise silk is still under the dummies for future
reference. Behind the cloth panel is a very small swell front, with shades
which open only about 45 degrees. After listening to the instrument, we decided
that omitting the shades made the organ considerably louder, and virtually
perfect in balance to a small consort of viols. Fortunately, there is a large
well behind the crown molding which provided a perfect storage space for the
shades. Reinstalling them would be the work of a few minutes should a future
owner wish to use the organ in its completely original state.

Wind system

The bellows still had its original leather, but every square
inch of it had been secondarily covered years ago with hot glue and rubber
cloth, probably by the same party mentioned earlier who went to such lengths to
remove the bellows plate from the organ. The rubber cloth and hot glue had
ossified into a stiff, inflexible board-like structure which had caused all
bellows hinging to rip itself apart upon inflation of the reservoir; the single
large feeder suffered the same fate. The bellows and feeder were completely
releathered with hot hide glue and goatskin. The bellows and feeder boards were
rather generously filled with splits, cracks and checks; the worst were
reinforced with butterfly-type patches, and all were entirely covered with
rubber cloth to prevent leakage.

The short wooden wind line which conducts wind from the top
of the bellows plate into the chest was originally simply fitted into place by
friction, but the horizontal members of the cabinet frame did not shrink and
expand in the same direction as the vertical boards of which the wind line was
made; in summer, as the cabinet expanded and lifted the entire upper assembly
away from the bellows, the leakage must have been spectacular. The joints
around the wind line had probably received more attention over the years than
any other part of the organ. Numerous layers of patching (leather, glue, rubber
cloth) attested to the trouble which this particular design flaw had visited
upon those who chose to play the instrument in humid weather. It seemed that a
change was necessary, so four small oak cleats were attached to the narrow ends
of the wind line so that it could be screwed securely to both the bellows top
and the bottom board of the pallet box. The cleats are clearly and
intentionally not a part of the original construction.

Chest

The chest was plagued by innumerable runs, and after some
investigation, they all were found to be caused by a joint in the table. The
front five inches or so of the grid is covered with a thin (1/4") mahogany
table. The rest of the chest is covered by one large pine channel block,
13/4" thick and honeycombed with many channels. The joint between the thin
mahogany and the thick pine channel block is naturally a source of some tension;
even though no crack had opened up between the two, the mahogany had almost
imperceptibly lifted along the joint. The problem was solved by screwing down
the mahogany piece with a screw in every rib, and by gluing a piece of thin
leather in each channel to bridge the joint. Should the joint ever move again,
the flexible leather should absorb the movement and prevent leakage. All key
channels, as well as all offset channels, were poured out with sanding sealer.
Shellac could have been used, but since the work was being performed in the
humid summer weather of East Tennessee, I decided to avoid shellac because of
the tendency of its solvent (alcohol) to absorb water from the air.

The bottom of the grid was originally covered in a thick
cotton covered with much shellac. We chose to replace it with rubber cloth.
Pallets were re-covered with two layers of leather, just as they were
originally, and they were installed in the original fashion, glued with hot
glue at the tail and held down by a small pine slat nailed on by tiny cut
nails. The builder evidently thought it was necessary to provide pallet sizes
commensurate to the wind demand, so the already tiny bass pallets (43/4"
long) were made even shorter at middle C (4" long).

Key and stop action

The keys are mounted on a balance pin rail at a ratio of
roughly 2:5. Thus, the pallets open a small, but nonetheless sufficient,
amount. Under the keyboard is mounted an elegant mahogany backfall (ratio 1:1)
which pushes down on very slender (.047") brass wire stickers. The
stickers pass through the 1/4" mahogany table, which also serves as their
register, and push the pallets open. All the stickers are original and the
action is pleasing to play and surprisingly responsive; in spite of the tiny
pallets, a definite pluck can still be felt in the keys. Key bushings are wood
on round brass pins, and the keys are covered in their original ivory. The
pallet springs are brass, clearly factory-made, and were still all perfectly
regulated when I checked them. No spring varied from all the others more than
1/4 ounce. I left them unchanged. The builder solved one problem with the
keyboard in a rather clever way. Since the keyboard is so short, it is not
possible to place the usual 19th-century style lead-weighted floating thumper
rail behind the nameboard. The builder instead installed the nameboard itself
in loose dados in the stop jambs so that its felted bottom edge simply sits on
the keys, keeping them in tension and making it possible to adjust them
perfectly level. When seasonal changes occur, the nameboard itself simply rides
up and down in the dados. (Of course, since this particular nameboard has no
actual name, it must be a nameboard in name only).

The stop action would seem to need no mention, except for
the stop to the left of the keyboards. The single knob to the right pulls on
the tiny slider for the Principal 4', which leaves the knob on the left with no
job to do at all. However, the builder thoughtfully provided a slotted block so
that the knob, which does absolutely nothing, can be pulled out just like its
brother on the right. The disappointing aspect is that the Principal had its
original engraved ivory disc, but the ivory disc on the left was missing. I
glued in a blank ivory disc for appearance's sake, but I will always wonder
what the label on the dummy knob said. Perhaps it might have even been engraved
with the builder's name.

Pipework

The pipework is unusual from the start in that both ranks
are metal: a Dulciana 8' and Principal 4'. The Dulciana has the usual wooden
bass of the period: large scaled, low cut-up and quinty. No identifying marks
were found on any of the pipes, not even on the seven zinc pipes of the
Dulciana (F18-B24). Early zinc often had an embossed stamp identifying the
(often French) manufacturer. The rest of the pipework is common metal. The
wooden basses were labeled in distinctive block lettering, with pencil, very
unlike the elegant old cursive one usually sees on 19th-century pipes. (I have
seen identical lettering on one other set of New England stopped basses which
the OCH found in an 1890s organ. The pipes were basses to a chimney flute, and
the entire stop had been completely reworked and re-scaled for its second use.
Alas, these pipes were also of unknown provenance).

I can find no rhyme or reason for the varying mouth widths
and variable scales. Surely part of the reason is that the common metal
pipework betrays the hand of a somewhat inexperienced pipemaker. While in
general neatly made, the solder seams are not as smooth and perfect as one
usually sees on 19th-century American pipework. It is particularly
disconcerting to see a pinhole of light shining through from the back of the
pipe when one is looking in through the mouth. These pinholes occur where the
back seam of the body meets the back seam of the foot at the languid, and are
present on several pipes. They did not particularly affect the pipes'
performance, so I left them. It does seem likely that scales were made
deliberately small in the tenor range of both ranks simply so that pipes could
be made to fit in the very cramped quarters. The very fat stopped wood basses
take up a huge amount of space, making it necessary to cram the metal pipes
into a very small area. Both ranks increase several scales in size from tenor
to treble: the Dulciana gets four scales larger, and the Principal increases by
three. (See pipe scale chart.)

From the chart, one can see that the cut-ups are all over
the map. The Principal seems to have a fairly even increase in cut-up toward
the treble, but the Dulciana seems to follow no discernible pattern. Mouth
widths are more predictable, generally hovering between 1/4 and 2/9.

The original pitch was fairly easy to ascertain. The pipes
seemed most comfortable speaking at 21/4"; at that pressure at 70 degrees,
the pitch was about A432. Since the whole point of this project was to make the
organ useful to an early music ensemble, the decision was made to fit tuning
sleeves carefully onto the pipes, and lower the pitch as much as possible. This
is a completely reversible procedure, with the added benefit being that it did
not require tampering with the tops of the pipes at all. The organ pitch is now
A421, not as low as the A415 the early music players had hoped for, but still
low enough that the instruments can tune to it easily.

One remarkable aspect of the tuning is that the Dulciana,
which showed no real signs of having been tampered with, was almost completely
in tune with the pipes at dead length and the few errant pipes brought into
regulation. A few chords quickly revealed that the keys of C, D, F and G were
close to pure, while the remote keys (B, F#, Db) were quite out of tune. This
sparked a lively discussion with Marian about temperament, and after some
research into early music temperaments (research done entirely by Marian) we
decided to tune the organ to Erlangen comma, which yields perfect thirds
between c and e, & d and f#. This temperament dates to the 15th century,
and is particularly suited to use with viols, avoiding the tuning conflicts which
mean-tone introduces between keyboard and viols.

Playing the organ is truly like stepping back in time;
voicing from this era demands less from each pipe than our modern ears
ordinarily expect. The gentle metal trebles in conjunction with the quinty wood
bass is a quintessentially early sound; virtually no one was still building
organs with that inimitable sound by 1860. Adding the small Principal 4' to the
Dulciana is an exercise in judicious restraint more than it is an augmentation
of the sound. All in all, it is an instrument from a different time and place,
built for sensibilities and perceptions unique to its milieu. Other than
changing the pitch, we did nothing to the instrument to make it more relevant
or modern. It so happens that leaving things as they were makes the organ
almost perfect for the customer's use. The subtle tone and slightly unsteady
wind work almost seamlessly with a small consort of viols da gamba. Placing the
instrument in a small room brings the sound into context, and music begins to
make sense on it. It is truly a chamber organ, and is at home in that
environment.     

The author wishes to thank Barbara Owen for her gracious and
invaluable assistance in seeking the origins of this instrument; Marian
Moffett, for her research on a multiplicity of subjects; and Will Dunklin, for
his generous help in bringing the organ to Tennessee as well as for insightful
advice during the project.

Sarah Mahler Hughes

Sarah Mahler Hughes is Professor of Music, Organist of the College, and Chair of the Music Department at Ripon College, where she has taught since 1989. In July 2002 she appeared as a guest recitalist at the XVI Festival Internazionale Storici Organi della Valsesia in Campertogno (Piedmont), Italy. A special scholarly/artistic grant enabled her to examine and play a number of historic organs in Germany, including the 1687 Schnitger organ at the church of St. Peter and Paul in Cappel. In July 2004 she examined and played historic keyboard instruments in the Russell Collection at the University of Edinburgh, Scotland and in other cities.

A recent holiday in Scotland provided many opportunities to see and play organs and other historical instruments in addition to being a tourist in this beautiful country. My children and I spent two weeks visiting friends in St. Madoes. Using this village between Perth and Dundee as our home base, we toured much of the country and experienced Scottish history and hospitality firsthand. The trip was made possible in part by a scholarly/artistic grant from Ripon College.

Our first stop was Edinburgh. En route to the Castle we wandered into St. Giles' Cathedral, where John Knox initiated the Scottish Reformation in 1560. The Chancel Choir of the First United Methodist Church of Lubbock, Texas, was rehearsing in preparation for a lunchtime concert, and I heard Mozart's Ave Verum Corpus accompanied on the beautiful 1992 Rieger. The organ is one of the instruments featured on the 2-CD set, Twelve Organs of Edinburgh.1

The next organ I saw, and the first one I played, was in Old Saint Paul's [Scottish Episcopal] Church in Edinburgh. Built by Henry "Father" Willis in 1888 and subsequently refurbished in 1905, 1936, 1960, 1968 and most recently, by Nicholson's of Worcester in 1977, the specifications are as follows:

The organ has a rich, warm sound eminently suitable for both service accompaniment and solo organ repertoire. A sample of the former may be heard on the CD Hearts & Voices, Hymns sung by the Choir of Old Saint Paul's Church.2

The following day I was privileged to spend several hours playing instruments in the Russell Collection of Early Keyboard Instruments in St. Cecilia's Hall at the University of Edinburgh. John Kitchen, Senior Lecturer and College Organist, was my tour guide as we worked our way through two rooms of virginals, spinets, and harpsichords from the 16th to 19th centuries.3 There were also three organs in the collection, and this seems the most appropriate place to mention them.

The first is an enharmonic chamber organ built by Thomas Parker in 1765. Parker was a pupil of Richard Bridge, a London builder favored by Handel.4 Bridge himself was supposedly trained by Renatus Harris. The  instrument has one manual with the usual short octave at the bottom. The real curiosity is a set of levers, two on each side of the case above the keyboard, that allow the player to select accidentals: Ab or G# and Bb or A# on the left-hand side, Db or C# and Eb or D# on the right. Parker provided a set of pipes for each pitch and the organ case is correspondingly wider than that of the usual chamber organ. What a fascinating way to learn firsthand about mean-tone tuning! It's also interesting to imagine how a player would handle a chromatic piece—assistants might be required to change the levers during a performance. The four registers of the organ include a Stopt [sic] Diapason 8', Open Diapason 8' (which only extends to tenor C, requiring both diapasons to be played together in order to use the full range of the keyboard), Principal 4', and Fifteenth 2'. Dr. Kitchen has recorded Stanley's Voluntary in G, op. 7, no. 9, and Handel's Fugue in A minor, op. 3, on the Parker organ.5 Interestingly, Parker built a second, two-manual enharmonic organ for the Foundling Hospital in 1768.

Another 18th-century chamber organ dates from 1763, the date when St. Cecilia's Hall opened. The organ was used in concerts until the hall closed in 1798. (The hall, having been refurbished in the 1960s, is once again the venue for concerts featuring instruments from the Russell Collection.) The third instrument, located in the Newman Gallery, is a Bernard "Father" Smith chamber organ from c. 1680. The specifications, which consist entirely of divided stops, are:

Wind is supplied through either a foot bellows or a modern electric blower. All of the above chamber organs reflect the disposition of English organs built after the restoration of the monarchy in 1660; i.e., principal stops at 8', 4', and 2' and, in the case of the Parker, stopped diapasons at 8'. The conventional registrational pattern of the time included solo stops plus accompaniment (hence the usefulness of the divided stops arrangement), diapasons (open plus stopped) for slow introductory movements, and full organ (8', 4', and 2') for faster movements. Stephen Bicknell has suggested that "There was a considerable revival of interest [in chamber organs] in the second half of the 18th century contemporary with (and perhaps because of) the great popularity of Handel, who seems regularly to have used small or even portable organs when playing continuo and for the performance of organ concertos as interludes to larger works."6   Bicknell also states that

By the end of the eighteenth century the chamber organ was firmly established as the instrument of choice for a well-to-do household, challenging both the harpsichord and the emerging fortepiano. The relative stability of tuning compared to a stringed keyboard instrument must have been an advantage, but it should also be noted that a small organ is a good vehicle not just for keyboard music, but also for transcriptions of instrumental works, and could readily be used for the accompaniment of family prayers.

He concludes that the organ's qualities of "reliability, versatility and dignity" must have accounted for its popularity.7

A greater contrast with these historical instruments than the McEwan Hall organ at the University of Edinburgh cannot be imagined. Built by Robert Hope-Jones in 1897, rebuilt by Henry Willis in 1953 and by Rushworth and Dreaper in 1980, the organ has problems because of the disparate placement of its divisions (the hall was designed without provisions for an organ, even though it was common for municipal concert halls at that time to include large instruments). Nonetheless, the organ sounds grand in the reverberant acoustics of the hall, where university graduations are held. The console looks a bit like a Jules Verne creation with its pressure gauges and electric dials, one of which is connected to the swell pedal to show incremental gradation (or "incremental frustration" as it's known to players).

The preceding organ and those described below all date from the second half of the 19th century, living testaments to the phenomenal rate of growth in organ building in England between 1860 and 1900. A few statistics tell the tale: in 1898, Harrison & Harrison of Durham claimed to have built 1,100 organs since 1861. Norman & Beard of Norwich produced even more astonishing numbers: between 1898 when their new factory was built and 1915 the company built over 1,000 new organs. In comparison, Sauer of Germany reached opus 1,000 only after fifty years of activity.8 Reasons for the rapid expansion in English organ building are numerous and include the wholesale replacement of older instruments, particularly those with a limited compass, increased prosperity of the middle class, which paid for new church instruments, and the construction of municipal concert halls in towns of any size.

The next organs I played were in Dundee, the fourth-largest city in Scotland. Three distinguished instruments exist in a three-block area in the heart of the city, which is pleasant and pedestrian-friendly. The first organ is located in St. Mary's Parish Church (Church of Scotland). I had not called ahead—in fact, I was simply being a tourist walking about Dundee and decided to poke my head in since the front door was open. Upon seeing the rich interior and a magnificent display of pipes in the rear balcony, I asked the volunteer guide if I might look at the organ. She very graciously assented, and I was delighted to discover a large three-manual instrument built in 1865 by Forster and Andrew of Hull and subsequently rebuilt by Rothwell (1939) and J. W. Walker (1969 and 1988). The console was open and inviting, so it was only a matter of minutes before I was actually playing. The specifications are:

A full battery of couplers and pistons plus an 8-channel memory system makes this organ suited for many kinds of repertoire. I only had time to try a voluntary by Stanley and a Buxtehude toccata before my younger daughter came looking for me (I'd left her and her sister parked outside), but I was impressed by the sound and feel of the organ in this parish church that in 1990 celebrated its octocentenary.

My serendipitous sampling of organs in Dundee continued on another day at St. Paul's Episcopal Cathedral. As churches go in Scotland, it is rather new, the cornerstone having been laid in 1853. The organ was built by Hill and Son of London in 1865, the year of the Cathedral's consecration. Hill, Norman and Beard reconstructed the instrument in 1975. Like the organs I saw in other British churches (with the exception of St. Mary's), this instrument is located in the choir with the pipes facing the singers. The organist's back is to the choir. The disposition of this large organ is similar to St. Mary's:

As was the case at St. Mary's, I was allowed access to the organ by helpful parishioners. When I arrived at St. Paul's on a Saturday morning, the only person I could find on the premises (even though the front doors were wide open and a charity hamburger stand was getting ready to open for business on the front steps) was the verger. He led me to the instrument, turning on power switches and lights as we went, saying "We have to show you Scottish hospitality!" I played for an hour, trying out various sounds and combinations and finally let it rip with the Widor Toccata. Feeling self-indulgent but happy with the sonic results, I set about changing my shoes and packing up when I was startled by two members of the flower committee who appeared and thanked me for playing. They told me that people in the street, hearing the music, had stopped to peer inside the church, probably wondering if a wedding were in progress.

A third large organ exists in Dundee within blocks of St. Mary's and St. Paul's. Situated approximately midway between the two churches is Caird Hall, Dundee's civic auditorium. The organ was built in 1922 by Harrison & Harrison to a design by the famous blind organist of Edinburgh, Alfred Hollins. The Caird Hall organ was Harrison & Harrison's first concert hall organ; as such it differs from some of their other instruments in having brighter reeds (on heavier pressure than usual) and more orchestral colors than the average church organ. In 1991 the organ was restored by the original firm with only minor changes to its original sound. No tonal changes were made, but the pitch was raised to make the organ usable with other instruments. Carlo Curley played the rededication recital on this occasion. A stoplist follows:

The organ's pneumatic action has been fitted with an electronic memory, and the combination pedals removed and replaced with toe pistons. Otherwise, the instrument remains as it was originally. A concert series in the early autumn featured the organ and it was recorded in October 2004. I was unable to play the Caird Hall organ because of a guitar festival in progress, but the staff was most helpful in showing me the console and wind system and providing me with specifications for the instrument.

Some general observations can be made, at this point, about the organs I saw in Scotland. The large instruments are originally from the 19th century and are based on an orchestral tonal design with a preponderance of stops at 8' pitch. The pedal divisions rely heavily on extensions from the manuals. Bicknell identifies the philosophy underlying this esthetic as ‘build-up:' "the gradual crescendo from piano to fortissimo achieved by adding stops one by one, [which] seems to be the dominant characteristic of these Victorian instruments."9 It works in this wise: flue pipes come in many colors, from clear and fluty to reedy with harmonic overtones. As the flues approach the reedy end of the spectrum, mild strings and reeds come into play, creating a smooth blend. Swell-to-Great couplers further increase fullness of sound while masking any addition of single stops, and the Swell pedal also assists in creating a smooth crescendo. As Bicknell points out,

This manner of playing was later to become an idée fixe with English builders and players . . . As a method it was taken so much for granted that it can safely be assumed that Willis's mixtures were not usually intended to be heard unless some reeds were already drawn . . . there is no provision for a chorus of principals and mixtures that can be used extensively on its own: this is . . . in complete contrast to German taste.10

Although the reference is to instruments built by Willis, the description is general enough to be applied to other large late-19th and early 20th-century organs.

Perhaps it seems incongruous that all of the organs I saw and played in Scotland were built by English firms. Were there no Scottish organbuilders in the 19th century and earlier? Regardless of how we might think of Britons as members of a United Kingdom, there are national differences among the English, Scots, Welsh, and Irish. A bit of research was necessary to unearth information about organbuilding in Scotland, from which a clearer picture emerges of the past three centuries.

At the heart of the question is the ban on instruments in church issued by the Church of Scotland from the Reformation (around 1560) until around 1868.11 Organs were allowed for concerts and domestic use, but none were built or installed in this denomination until a very late date. Other denominations—the Episcopal, Roman Catholic, Unitarian, Congregationalist, and Baptist churches—were exempt, and instruments dating from the 18th century are known to have existed in them.12 Early 19th-century Scottish organbuilders, including Small, Bruce & Co of Edinburgh, John Renton, also of Edinburgh, and Robert Mirrlees of Glasgow, specialized in chamber organs, at least two of which are extant.13 I was very surprised to learn that the oldest surviving Glasgow-built organ was made by James Watt in 1762. The renowned engineer and inventor, associated more with the first steam engine than with pipe organs, constructed a single-manual instrument concealed in a table. It was the first of three organs built by Watt.14

In the second half of the 19th century, other firms arose in Dundee, Aberdeen, and Edinburgh, but they found it difficult to compete with the well-established English builders. An admittedly cursory search for information on Scottish builders in the 19th and early 20th centuries produced nothing—but perhaps a written history is in progress.

Today, Lammermuir Pipe Organs (est. 1983) is perhaps the best-known firm in Scotland and the only workshop "north of the border" specializing in new, mechanical-action organs.15 Op. 50 is scheduled for completion in 2005. The other company listed in an Internet link to pipe organ builders in the United Kingdom is Michael Macdonald (est. 1975) of Glasgow.16 Interestingly, besides building new instruments, Macdonald engages in rescuing historic organs from redundant buildings (primarily churches closed due to dwindling congregations).

I would like to think of my visit to Scotland as a prelude to further organ crawls  there and in other parts of the United Kingdom. There are many instruments to be played and much history to be learned in these islands.

Introduction

The modern "orgelbewegung" organ revival has cultivated as a norm the German neo-Baroque organ, using stopped or partly stopped flutes as foundations at 8' and 16' pitch in small instruments. This practice has been given such authority that many organists do not question it; but this type of organ is only one style among many. Neither it nor any other design ought to be raised to the level of dogmatic acceptance. The multiple foundation stops found in the best nineteenth-century organs  represent the continuation of a tradition which had been already established in the Baroque period. A perception of the history of the organ which does not ignore the nineteenth century should lead us to see that multiple foundation stops in the manuals are consistent with eighteenth-century practice and not the exception.

In this paper, the presence of such stops in important examples is noted and described. It is observed that some organs of the eighteenth- and nineteenth-century have an extraordinarily cohesive blend of stops in various combinations. An acoustic theory is put forward to explain the reason for this blend or its absence. This theory states that stops are able to blend when harmonics are present in the unison tone which duplicate the fundamentals of the upper pitches. It is also observed that stopped pipes used as foundations cannot provide these harmonics.

A most important application of this point of view is that the pedal of a small organ may be based upon a 16' open subbass, not the traditional stopped bourdon. Several organs are cited which demonstrate this practice, from the eighteenth, nineteenth, and twentieth centuries. It is noted that in the manual divisions the Italian organs used 8' open pipes as foundations through their entire history; however, the Italian organ has generally been ignored as a model for small instruments. It is concluded that the exclusive use of stopped pipes as fundamentals in small organs should be reconsidered. The extensive use of stopped flutes represents a restricted, national style which ought not assume the role of a universal model. Open pipes blend better and make the tone more cohesive. We should question accepted norms of "organ design" and revise them in favor of those traditions which include the use of open pipes to provide the fundamental tone. This will allow organs in churches to be most effective at their primary role, to provide a foundation for congregational singing.

Historical Background

With the neo-Baroque organ revival, organ scholarship blossomed and has resulted in the construction of new instruments re-creating stop lists that belong to specific national or regional styles of organ building. These instruments reflect earlier times and their respective literatures. These trends were transmitted remarkably quickly to North America. This was accomplished primarily by North American scholars studying abroad and by European specialists teaching in North America. Some years later these same trends appeared in other English-speaking countries such as Australia. This organ revival filled a particularly heartfelt need resulting from a discontinuity of the traditions of organ building which was most evident in the "orchestral" and theatre organs of the 1920s.

It is not a simple matter to establish exactly why traditional concepts of organ building were abandoned, but if any one cause is to singled out, it must be that certain types of electric action made possible the use of the same pipes at two or more pitches (unification) or on two or more keyboards (duplexing)1. These purely technical devices of organ design, made in the interests of a certain type of economy, made it impossible to voice the organ so that its stops could blend. This break with the traditional concepts of organ voicing set the stage for rediscovery of older traditions, rather than allowing a normal evolution of organ design. When it became obvious that something had been lost through neglect, there had to be a "revival" so that whatever it was that had been lost could be reinstated.

Unification and duplexing destroyed the blending ensemble so thoroughly that, despite the effects of the organ revival movement, we have not yet recovered the consciousness that the stops of an organ must truly blend together. The result is a genuine anachronism: the separate stops of many modern organs refuse to blend, while there still exist a few forgotten nineteenth-century instruments, the best from their time, which preserve the ability of every one of their stops to blend with every other. While the "revival" organs do not have unification or duplexing, often they show an indifference to blend that can be traced to the disastrous lapse of sensitivity in voicing that unification and duplexing have left as their aftermath.

New Organs in North American and Australia

One result of the organ revival has been the crystallization of the neo-Baroque stoplist into a norm for the construction of new organs. But because a "revival" resurrects an older stratum of the culture which has already passed away, the organ revival reflects the specific requirements of a style of organ playing which is no longer in an active phase of development. The "revival" organ often reflects the general requirements of eighteenth-century organ playing and the specific demands of German Lutheran organ literature. It is now customarily imposed upon English-speaking regions of the world, regions which possess traditions and literatures vastly different from those of an eighteenth-century culture. This neo-eighteenth-century norm presents itself virtually as a doctrinal system, often assuming a degree of authority that is insisted upon in the same way that a theological principle may be insisted upon.

The North American adoption of the neo-Baroque organ design was a "marriage of convenience" to aid the recovery from the theatre organ debacle and its after-effects. It has persisted quite a bit too long. Now we are being called to take up once again the historical evolution of the instrument.

The objective of the author is to develop a theory of organ registration and specification that does not reflect the demands of any national or regional style. Instead, it is a theory of organ specification which proceeds from an acoustic basis. It is intended to fulfill the needs which we find in English-speaking churches at the end of the twentieth century. Like the ancient eclectic philosopher, we have selected such doctrines as please us from every school. Our music borrows freely from many sources, and is not exclusive to any one tradition.

The Nineteenth-Century Contribution

In Australia, New Zealand, Canada, the United States and Europe, there still exist nineteenth-century organs virtually untouched or relatively intact, preserving a tradition of organ building which has largely been lost in the major population centers. A number of these organs are being rehabilitated and it is no longer fashionable to take away their original characteristics. Restorations, not rebuilds, are becoming more common. An example is the organ formerly of St. Stephen's Roman Catholic Cathedral, Brisbane, built about 1880.2 This old instrument survived the rebuilders because of the happy circumstances of benign neglect. Fortunately, there was not enough money available to replace or "modernize" it.

This organ features tracker action, low wind pressure, bright reeds, and clear but not loud upper work. Everything rests upon a foundation of several unison stops and all reasonable combinations of two or more stops can be depended upon to combine into a blend of great cohesion. These factors suggest that this organ represents an evolution of the traditions of organ building which had been current during the century before. Though the sound is quite different from a Baroque organ, there is no radical departure from the eighteenth-century traditions, but rather a continuity with them. The result is that the music of both Bach and Brahms sounds very comfortable on this instrument.

The Great manual of this organ corresponds almost exactly to the Baroque ideal in the plan of the stops and their assignment at various pitches. The character of the stops has changed according to the styles of the period, but the essential design of the ensemble is preserved. As a model for comparison the specification of the Great manual is given from the Löfsta Bruk organ of 1728 by the Swedish builder Cahman,3

It is apparent from nineteenth-century examples (for instance, by E.&G.G. Hook and others in Canada and the United States), that tracker action, low wind pressure, bright reeds, upper work and mixtures were all elements of organ building that had been carried over into the nineteenth century from the eighteenth century. What about the multiple unison stops? Do these represent a "Romantic" tradition only, or are they an element that was being carried over from the Baroque period into the Romantic era? In both organs cited above, there is an open 8' to serve as the foundation for the ensemble, a wide-scaled flute to give it depth, and a third 8' stop to contribute the harmonics necessary to bind the ensemble together. In the eighteenth century, these harmonics were provided by the Quintadena, meant to act together with the Principal 8'. In the nineteenth century the Diapason had a wider scale than the eighteenth-century Principal. Therefore the third 8' stop, which must contribute the binding harmonics to the ensemble, is the Gamba, a string-toned stop of such wide scale in this organ that it is very much like a narrow-scaled Violin Diapason.

If we emphasize the similarity of the two stop lists rather than their differences, we can obtain a better view looking back at the eighteenth century and also looking forward to the twentieth century. It is possible to theorize on specifications which can accommodate not only the music of Buxtehude and Bach, but also the other portions of the literature, such as that by Dupré or the French symphonists, which have grown out of the traditions of the nineteenth century.

The Difference between "Registration" and "Specification"

Organ specification is not the same thing as organ registration. A specification is a list of the various stops of which a particular instrument is composed. Registration is the setting down of certain combinations of stops in order to produce a desired effect. In a given organ, there is a specification of stops which should combine together to give the instrument a distinctive musical formulation, which we call "ensemble", all the parts of which match together and harmonize. From this specification, an indeterminate number of registrations may be drawn, which express various facets of that distinctive musical ensemble. The full organ registration should be equivalent to the specification of the instrument less certain stops intended for special effects.

The specification of an organ should be built up, not to make combinations, but rather to provide for maximum blending of stops. Blending stops may be pursued in two directions--vertically (8', 4,' 22/3', 2' etc.) and horizontally (8' + 8', 4' + 4'). The 8' and 4' accompaniment stops, which are flutes, should blend horizontally with the principal chorus. How often have students been admonished not to combine stops of the same pitch, because of tuning problems! In nineteenth-century organs, the 4' flute was usually open or harmonic and combined naturally with a 4' principal, rather than beating against it. Both the Brisbane organ and the Löfsta Bruk organ present an open 4' flute capable of combining with a 4' principal. This is not a new characteristic making its first appearance in the nineteenth century.

The reed stops should blend horizontally with both flutes and principals. There ought to be maximum harmonic reinforcement between the reeds and flues--that is, there should be no sour off-harmonics in the reeds. Therefore, full-length reeds are to be preferred to half-length reeds, which have a peculiar harmonic series with flat ninths and so on.

Finally, at least one mixture stop may contain a tierce, in order to assist in the blend with the reeds. This characteristic occurs in both the Brisbane and the Löfsta Bruk organs. We can see from the above, that specification is the organ builder's art. Specifications should not be made up to encompass the most possible registrations. Rather, the various registrations should be derived from each organ's individual specification. The specification of a particular instrument should be set up to secure the maximum possible blend, both in the horizontal and vertical directions. From a specification may be derived two contrasting types of classes of registrations: blending registrations and non-blending registrations. These are defined and discussed below.

The Harmonic Overtones of Open and Stopped Pipes

It is well known that all organ pipes produce composite tones consisting of various harmonic partials.4 The partials of 8' open pipes which concern the present theory of registration are these:

First partial = Fundamental

Second partial = Octave = Fundamental of 4' stops

Third partial = Quint = Fundamental of 22/3' stop

Fourth partial = Double octave = Fundamental of 2' stop

Fifth partial = Tierce = Fundamental of 13/5' stop

The fundamentals of the 4', 22/3', 2' and 13/5' stops all reinforce harmonics already present in tone of the open 8' stops. Therefore the 4', 22/3', 2' or 13/5' stops will blend acoustically with the open 8' stops.

The stopped pipes, in contrast, behave very differently. They emphasize only the odd partials. Those partials of stopped pipes which characterize their tone are these:

First partial = Fundamental

Third partial = Quint = Fundamental of 22/3'stop

Fifth partial = Tierce = Fundamental of 13/5' stop

These stopped pipes form strong blends with mutation stops, but not with the octave-sounding registers of the principal chorus.

"Blending "and "Non-Blending" Registrations

"Blending" registrations are defined here as those registrations which consist of stops arranged in such a manner that the harmonic overtones of the lower stops duplicate the fundamental tones of the higher stops.

Examples:          Open 8' (Principal)        +              open or stopped 4'

                  Open or stopped 8' (Principal or Quintadena)                  +             22/3' Quint

"Non-blending" registrations may be defined as combinations of stops arranged in such a manner that the harmonic overtones of the lower stops do not duplicate the fundamentals of the higher stops.

Examples:          Stopped 8'         +               stopped 2' or open 2'

                  Stopped 8'         +              stopped 4' or open 4'

Blending registrations are used for music which demands the full chorus attribute of the organ. Non-blending registrations should be used where the music is to stress the maximum independence of line, such as in the typical bicinium type of chorale prelude.5

Some compositions may feasibly use either a chorus type of registration or a contrasting non-blending registration which stresses independence of line. Hence the dividing line between the two types is not clear. To express this ambiguity of intention, hybrid registrations are useful. Some of the stops blend with each other, while some do not.

Examples:           Open 8'                +              stopped 4'          +              open 2'

                  Stopped 8'         +              open 4'                 +              open 2'

In the first example, the open 8' combines with both the stopped 4' and open 2,' but the open 2' cannot combine with the stopped 4' because there is no 2' partial in the stopped 4'. In the second example, the stopped 8' can combine with the open 4', but not with the open 2'; also the open 4' and open 2' can combine with each other. For both examples, the character is not clearly either "blending" or "non-blending." Registrations with this property might be best used in music which has three or four voices where both the cohesion of the lines and their independence are to be stressed simultaneously.

These observations lead to the conclusion that successively higher pitches in a registration should be more open acoustically.

Example: Stopped 8' + partially open 4' (Koppelflute or Rohrflute) + open 2.

Single stops can also exhibit this hybrid characteristic. For example, the bottom octave may be stopped, the next octave partially stopped, and the treble fully open.

Composite Solo Registrations

The foundation 8' flutes should contain the 4,' 22/3', 2' and 13/5' partials, so that the mutation stops can join with them acoustically. The 4' flutes should contain prominent quint partials, if there is a Larigot or quint at 11/3' above. A conclusion which follows from this type of design is that the stop which determines the musical quality of a Cornet V is the 8' flute that supports it, rather than the mutations of which the Cornet itself is composed.

Solo registrations involving reed stops may be either blending or non-blending. It is interesting to contrast the combination Oboe 8' + flute 4' with the combination Clarinet 8' + flute 4'. The action of the flute in each case is different. There is, however, a little of every harmonic to be found even in the hollow-sounding reeds such as the Clarinet and the Krummhorn, because the reed itself produces a full series of partials.

If we contrast the registration Oboe 8' + quint 22/3' with Clarinet 8' + quint 22/3' we find that the adhesion of the quint to the Clarinet is stronger than the cohesion of the quint with the Oboe. This happens because the quint harmonic (22/3') is much stronger in the Clarinet than it is in the Oboe. A composite solo registration may be used with either a blending or a non-blending accompaniment registration, depending upon the character of the accompanying voices.

Conclusive Statement of Theory

This present theory of registration is easy to apply. If a stop at a lower pitch contains a harmonic that can bind with the fundamental of a stop at a higher pitch, then those two stops are capable of a good blend. If not, they will be limited in their capability of blending, or prevented from it altogether. An ensemble composed from a "non-blending" specification (such as is found in small neo-Baroque "revival" organs) comes out in layers, rather than producing a blended, cohesive, and "blooming" sound.

Specification of Foundation Stops at 8' and 16' Pitches

A practice which flows from the acoustic analysis of specification is the placement of open and partially stopped flutes at the 8' pitch in the manuals and at the 16' pitch in the pedal organ. This is much in contrast to the idea of placing them exclusively at the 4' pitch and higher in the manuals and only from the 8' pitch upward in the pedal. In the manual divisions, the economy of the organ and the space it requires are not greatly affected, since in most cases the bottom octave of open flutes at the 8' pitch is stopped and made of wood to assure quickness of speech. The provision of a narrow-scale open subbass in the pedal requires room overhead and this stop is expensive; but this expense should be more than offset by the fact that such a pedal division is more versatile and blends so much better than the alternative. The organ can be made a stop or two smaller than might otherwise be planned. The expense of the open 16' stop is more than recovered because a smaller pedal organ will actually sound better and more compelling.

When the pedal is based upon a 16' open flue, producing a relatively quiet tone--about the same intensity as a normally stopped Subbass 16'--there is an exquisite blend of harmonics. The upper partials of the soft open 16' are able to combine with the fundamental tone of the various members of the chorus above, particularly the 8' Principal.

This is the design of the pedal organ specification which is found in the Cahman organ of Löfsta Bruk.

Öppen Subbas 16'

Principal 8'

Gedackt 8'

Kvinta 51/3'

Oktava 4'

Rauschkvint II

Mixtur IV

Basun 16'

Trumpet 8'

Trumpet 4'

It is exceedingly rare. Cahman also did another interesting thing. The combination Gedackt 8' , Quintadena 8' and Quint 22/3' is repeated both in the Great and Positive organs. Are we to realize from this repetition that Cahman provided the Quintadena 8' in each case to secure an acoustical, harmonic "locking in" with the quint 22/3' above it? Most modern specifications would have omitted the Quintadena, probably on both manuals, and supplied a stopped 16' to the pedal, substituting for the Open Subbass 16' a louder Principal 16'. The particular quality which sets this Cahman organ apart as a gem among artistic instruments would be destroyed.

The Open Subbass of the Löfsta Bruk organ is made of wood and has a fairly narrow scale. In the published photographs of the organ, the end of the largest pipe can be seen behind the 8' Prestant of the pedal organ. The lowest pipe is approximately seven inches square. If this principle of specification and voicing is to be retained in an organ large enough to offer both an open and stopped 16' flue in the pedal, it is important that the open stop be of narrow scale and voiced quietly so as to support the chorus above. When 16' open flues are scaled and voiced loudly, so as to "add power", their harmonic development is much reduced and their ability to contribute to a unified chorus ensemble is lost. Therefore the 16' open flue stop should be planned to be no louder than any stopped 16' open flue which may accompany it in the pedal.

An Example of the 16' Open as the Only Pedal Foundation Stop in a Modern Organ

The Casavant organ at the Dordt College chapel at Sioux Center, IA, was built under the supervision of the late Gerhard Brunzema. It is a 37-stop instrument which contains only principals and reeds in the pedal according to this disposition.6

Praestant 16'

Octaaf 8'

Octaaf 4'

Mixtuur VI

Bazuin 32'

Bazuin 16'

Trompet 8'

Cornet 2'

Since there is only one 16' flue stop, this stop also has to be able to fulfill the role normally taken by a stopped 16'. Therefore it must not be loud. But if the 16' foundation cannot be loud, how is power to be built up? The Sioux Center organ relies on its reeds rather than its flue stops for power in the pedal organ. This also happens in the Löfsta Bruk organ.

The Use of Mutation Stops to Support a Pedal 16' Flue Stop

The Löfsta Bruk organ builds power for its 16' flue both through its reeds and through a 51/3' pedal quint. This method of building power and clarity without overvoicing the 16' flue stop was followed regularly by the late Nils Hammarberg, a modern Swedish organbuilder of Göteborg. A stopped 8' pipe acquires definition though the reinforcement of its third partial, the 22/3' Quint. The Quint's fundamental is the same as the third partial. Cahman specified a Quint 51/3' in the pedal organ to complete the same harmonic function that the 22/3' Quint fulfills in the manual divisions. The combination of a soft open 16' together with a quint supporting its third partial gives the pedal organ a firmer foundation than any loud, wide-scaled diapason could ever provide.

The mutation stop must be narrowly scaled and gently voiced, and a true principal rather than a flute. This is also a prominent characteristic of the 22/3' and 2' stops in the Great organ of the nineteenth-century Brisbane instrument in Australia. Blending tone is aided by conservative scaling and gentle voicing, both of the fundamental tone and its corroborating harmonic.

Hammarberg continued this tradition with the provision of a pedal stop called "Aliqvot," a name which simply means "harmonics." It can refer to any useful combination of supporting harmonic partials. In his most recent work it consisted of the following 16' partials:

51/3' quint = third partial

31/5' tierce = fifth partial

22/3' quint = sixth partial

2' fifteenth = eighth partial

Hammarberg developed this idea because in Sweden, organs are placed in the gallery at the western end of the church and there is no headroom for open 16' pipes. It substitutes for the open 16' sound a resultant:

                  Alikvot                  51/3' C                  96 Hz

                  Principal               8' C        64 Hz

                  difference                               32 Hz = 16' C

He also provided the 32' resultant in the same way:

                  Kvinta 102/3' C               48 Hz

                  Principal               16' C     32 Hz

                  difference                               16 Hz = 32' C

Sometimes the Alikvot mixture has less than four ranks and sometimes more; Hammarberg sometimes built it in the following way:

51/3' quint = third partial sounding G

31/5' tierce = fifth partial E

22/7' flat seventh = seventh partial flat A#

17/9' ninth = ninth partial D

A typical specification for such a pedal organ is:

1. Subbas (wood, stopped) 16'

2. Kvinta 102/3'

3. Principalbas 8'

4. Gedacktbas 8'

5. Alikvot 51/3' + 31/5' + 22/3' + 2'

6. Bombard 16'

7. Trumpet 8'

8. Rörskalmeja 4'

9. Koralbas 4'

Hammarberg built this plan in conditions where headroom was restricted, from about 1981, and used the Alikvot mixture as well as the 102/3' plus 16' resultant in various instruments dating from the 1960s and 1970s. Examples of this work may be found in Mora, Boras, Göteborg, Falkenberg and Grebbestad, all in Sweden. In all of these organs, the presence of the Alikvot stop relieves the 16' from any obligation to attempt to produce power through volume, with the attendant deterioration of its tone.

Hammarberg's plan of pedal specification works well with gently voiced open 16' flue pipes, to develop a pedal organ of considerable power, while allowing the open 16' flue to remain as the only 16' flue stop in the division. Hammarberg's ideas combine well with Brunzema's plan (above) to give the following:

1. Subbass 16' wood, open narrow scale, about 7≤ CCC as at Löfsta Bruk

2. Quint 102/3'

3. Principal 8'

4. Gedacktbass 8'

5. Quint 51/3'

6. Coralbass 4'

7. Alikvot, composition as appropriate

8. Basun 16'

9. Trumpet 8'

10. Rohrshalmey 4'

Summary

The modern organ reform movement has given strong support to the exclusive use of gedackts and other stopped pipes at 16' and 8' pitch in small organs. This type of specification is derived from a "Neo-Baroque" Germanic tradition of organ building. Although these stopped pipes sometimes have narrow chimneys as in the Rohrflute, they nevertheless act as stopped pipes in the ensemble. This practice of specification leads to a form of non-blending registrations.

It is curious that the Italian organ, in which one always finds open pipes for foundation tone, is hardly built today, while the typical "reform movement" type of instrument, with a high percentage of stopped pipes, is commonly built. This is not merely a result of economic considerations, but rather a question of style and fashion.

Derived from this background is the practice of specifying a stopped Subbass as the pedal foundation stop. It provides the fundamental pitch in an undefined sound that blends with difficulty; and when pushed to provide greater volume, its tone deteriorates very quickly. A stopped Subbass has little blending power because it has no harmonic at the octave. This defeats the purpose for which it is intended. A 16' pedal stop should do more than supply a fundamental pitch; it should provide a harmonic series to support the chorus above.

We have examined pedal organ designs by builders who have not frozen their thinking into traditionally accepted ideas. The contemporary organs of Brunzema and Hammarberg take much of their design from the organ reform ideals, but also demonstrate innovative ideas which reinforce the true acoustical nature of the instrument. Let us turn to models such as these, rather than the typical "organ reform" prototypes, in order to construct organs of moderate size that do not lose our public for want of a good foundation for singing.

If we emphasize gently voiced open pipes as the natural source of fundamental tone, and obtain the power of the organ by means of harmonic reinforcement, we will assure that its sound has that live-giving warmth which will appeal to the musical public.8

The Löfsta Bruk Organ

by John Hamilton7

The sumptuous Löfsta Bruk organ was built in 1728 by Johan Niclas Cahman, a North German builder who had emigrated to Sweden. Of twenty-eight registers (two manuals, pedal), it was conservatively conceived; it is today Scandinavia's finest example of the sort of instrument known to the Praetorius/Scheidemann/Scheidt/Buxtehude school. The lavishness of conception is indicated in, for instance, the pedal's two full-compass full-length sixteen-foot registers, a Principal and a Posaune--in a church seating barely three hundred. The organ has largely escaped the periodic "modernizations" which have plagued many important old instruments. When nineteenth-century tastes called for a different sort of churchly music-making, the Ryggpositiv windchest and pipes were carefully removed and stored in the church's attic; Romantic tastes were satisfied by the two-manual-and-pedal reed organ which replaced the Ryggpositiv. A restoration in the early 1960s, by a Danish firm, was in the tradition of the best obtaining taste of that decade; it was well carried out but, alas, today's wind-supply is the mercilessly steady nineteenth-century norm, today's temperament is nineteenth-century equal, today's reed tongues are modern (the restorer discarded the old tongues without making measurements or metal analysis), and today's key action possibly is overly spring-loaded. Plans are afoot to correct these modern intrusions.

Tone is big, noble, unforced, in the north European historic tradition. Plenums admirably support the ardent congregational singing known to have characterized the eighteenth century: today's listener readily envisions vigorous hymn singing from strong-lunged Walloon ironwrights, who sat together in the church's most prestigious area. Of particular interest are the organ's mixtures, all of which contain third-sounding pipes contributing strength and color to the plenums. Individual Principal registers are among the most gloriously singing known to this listener.

Today's organists at Löfsta Bruk are Birgitta Olsson, the excellent parish organist, and Göran Blomberg of Uppsala University, who with a background in musicology, organ performance, and classical archaeology, is a strong summer presence. Blomberg's personal involvement with the instrument coincides with the period of its modern international reputation starting around 1980; his tireless, knowledgeable commitment to its becoming known have resulted in the organ's having become widely recognized even earlier than was the village itself. He has recorded an excellent selection of material by Buxtehude and Bach on an LP released by Bluebell-of-Sweden and is preparing digital recordings. Birgitta Olsson and Blomberg have organized a succession of summer "Cahman Days" forming an annual framework for presentation of the instrument; these included an international festival in August 1987, during the Buxtehude anniversary. And Blomberg offers numerous demonstration recitals on the instrument for groups of both lay and professional visitors.
