An Acoustic Basis for Organ Specificiation and Registration

Part two of two

The balance of this article will explore some of the methods used by Schoenstein in designing symphonic organs.

Tonal Variety

In planning a symphonic organ, no tone color that might be useful is excluded from consideration, and if something new seems appropriate we will develop it. We see no problem in combining individual sounds from French, German, English and American traditions of different periods in one instrument. This may seem like a dangerous approach, and it is . . . for those who must follow only established rules. If, on the other hand, a designer has in mind a well-formed image of the tonal architecture and its end result, the freedom to include elements of rare beauty handed down to us by the great builders of the past can open new avenues of creativity. This approach is only successful when applied with the strictest of discipline. Anything that does not blend and pull its weight in the ensemble or serve in a variety of solo or accompaniment roles should not be included. Collecting multiple elements of different traditions in an attempt to combine two or more repertoire-specific instruments into one is usually disastrous. The once-popular procedure of building an organ with a German Great and Positiv and French Swell or adding a romantic Solo to a neo-classic design are ideas that have, fortunately, lost their appeal. The goal should be to create an ensemble that has integrity in its own right and is able to acquit itself musically in a number of different styles with such conviction that there is no need to claim “authenticity.”

An equally important rule of design is to avoid making an instrument any larger than necessary or practical. No organ should have more stops than it needs to get its musical job done. No organ should be so large that it becomes unseviceable or acoustically chokes on its own bulk. When too much organ is squeezed into too little space and/or spread hither and yon, maintenance and tuning problems are sure to result. An organ should be of adequate size to be considered symphonic, but that size is much smaller than one might think. The smallest organ we have made that can qualify is the 15-voice, 17-rank instrument in the chapel of the University of St. Thomas, Houston, Texas (see stoplist). Certainly 40 to 50 voices provide ample opportunity for design freedom and 60 to 70 voices are all that should be required even for very big buildings. An example of our approach in a large symphonic plan is at First Plymouth Congregational Church in Lincoln, Nebraska (see stoplist). Note that this instrument has 73 voices if the separate gallery organ is not included.

Our stoplists show how we combine various tone colors, but a few explanatory notes may be in order. When combining individual stops into groups, we think of them in these categories: first, traditional choruses of diapasons and reeds; second, stops of moderate power from all tonal families serving in both accompanimental (manual and pedal) and in solo roles; third, ethereal stops--the extremely soft and delicate tones of the flute, string or hybrid type; fourth, bass stops of exceptional depth and power; and fifth, heroic solo stops. Some stops, of course, can fit into more than one of these categories but the classification is useful in reviewing whether or not the organ has all of the tonal characteristics common to a good symphonic ensemble.

Since the diapason is unique to the organ and the tone most often used, we seek to provide several (with appropriate chorus development), each of distinct character, on organs of even modest size. They vary not only in scale, but in mouth width, slotting, etc. We like to include stops of the echo diapason class (dulcianas, salicionals, etc.) as well. During the organ reform movement, open flutes, particularly at 8’ pitch, were not in vogue. We tend to include more open than stopped flutes. Stops of genuine string tone have not been popular either. This is a sad omission and certainly an organ without them cannot be considered symphonic. We like to include a family of strings and celestes from very narrow to very broad scale, all with true string quality rather than the geigen principal type that served as string tone in neo-classic organs. We try to include at least one of each of the color reeds (Clarinet, Oboe, Vox Humana and, where possible, horns, and specialty stops such as the Orchestral Oboe) as well as a complete chorus of trumpet tone (in large schemes, those of both closed and open shallot type). To broaden both dynamic and color ranges, very soft flue stops (often of the hybrid, tapered types) and bold solo stops (usually of the trumpet or tromba class) are important. In small schemes these effects can be had with stops doing double duty through effective expression.

We have developed several new voices. Some of these are variations on long established styles such as our Celestiana, which is a very narrow scale, quarter-tapered hybrid of clear but very soft flute tone; the Cor Seraphique with its Vox Angelique celeste is a larger scale version. Our Corno Dolce and Flute Celeste are brighter renditions of the E. M. Skinner Flauto Dolce and Flute Celeste. We find this bright character more generally useful in smaller instruments. The Voix Sérénissime is a small scale string of extremely keen intonation but of soft volume. The Silver Flute is a narrow-mouth, non-harmonic version of our large Harmonic Flute. It may be thought of as a metal Claribel Flute. 

The Symphonic Flute is a new development, also called Bœhm Flute, incorporating many different pipe constructions throughout its compass to achieve an interesting effect found in the orchestra’s family of transverse flutes. The flute of the symphony orchestra is bright and reed-like in its lower register with a full, increasingly powerful and pure, bell-like treble. These tone qualities are carried downward to the alto, bass and contra-bass flutes and upward to the piccolo. The Symphonic Flute was realized after extensive studies with flute players and manufacturers, as well as a careful review of Bœhm’s treatise. The tonal character is achieved, as in real flutes, by maintaining nearly the same diameter from bass to treble. The diameter progresses unevenly to achieve particular effects, but it does not reach the half-way point until the 48th pipe. The pipes in the bass therefore are of string scale progressing through principal, moderate flute, a wide flute, to very wide flute at the top. Pipe construction is of five varieties: slotted; non-slotted; harmonic; double mouth harmonic; and double mouth, double harmonic. This new solo color for the organ is both powerful and beautiful.

We employ high wind pressure for beauty, precision, or smoothness of tone where it is required. Solo flutes and strings and all closed shallot chorus reeds certainly have benefited from this treatment. Loudness can be achieved by other means, but carrying power without harshness is most perfectly achieved through heavy pressure.

A final note on tone is perhaps the most important point in this essay: Beauty of tone trumps all else in organ design. Beauty is perhaps too simple a term. Organ stops of great character can be quite bold and assertive, colorful and mysterious, languid and wistful. They are all forms of beauty to my ear. The secret is committed voicing. By that I mean making tone that has something to say, not simply playing it safe with blandness. Anyone who studies organ tone knows what I mean. Great voicing imparts something extra to energize a tone and make it appealing. A single diapason of beautiful quality will outplay a 100-rank organ that is all bluster and blandness. An organ may look symphonic on paper, but if the character of tone is not beautiful, it cannot qualify. An organ of any type with beautiful tone will surpass a poor symphonic one. However, if beauty of tone can be combined with all of the flexibility promised in the symphonic ideal, the result can be sublime.

Balance

To achieve balance there must be a center of gravity and in the symphonic organ it is at 8’ in the manuals. Each division should lay its foundation at the 8’ level. This, after all, is where the music is written. In our symphonic concept, upperwork is considered a coloring agent, a way of adding a distinctive character to the 8’ line. Therefore, in chorus design, as a general rule, scales decrease as pitch levels increase. Where we have the luxury of two mixture stops in a division, we vary them in color and dynamic rather than pitch: for example, one at mf and another at ff or one with a tierce and one without. Sometimes the mixture is enclosed separately. We avoid flutiness and overemphasis of off-unison pitches in upperwork; pure, clear diapason tone is the goal. Most 8’ stops, particularly those that must blend with related upperwork, have high harmonic content, a satisfying brilliance in their own right. Eight-foot stops are also regulated in a treble-ascendant fashion to emphasize the melody line; pipes become progressively slightly louder as they ascend the compass from the middle of the keyboard.

Horizontal balance is equally important and we believe that all of the manual divisions should be of adequate power to balance one another; the Swell and Great approximately equal and the Choir only slightly below. Reeds and flues should be equally balanced, but in certain acoustical situations the reeds should dominate. In dealing with chambers or in rooms of dry acoustic, open flute, string, and chorus reed tone are far more effective in producing tone of noble and powerful character than is diapason upperwork.

Clarity

One only has to see the density of a Reger, Widor, or Elgar score to realize that clarity is vitally important in romantic and modern music--as much as in early music. Many organs just present great blocks of sound. This may be titillating, but it is not music making. The notes must be heard if the intent is to be expressed. Most of the burden for clarity rests on the organist, who must judge his instrument and his acoustic; but the organ must not stand in his way. Clarity is achieved in an organ by many means including steady wind, precise action, voicing for prompt, clean attack and clear tone that is steady and free of irritating chiff, wild harmonics, and white noise.

Enclosure

There are vital qualities of freshness and presence associated with unenclosed pipework, but we believe that having pipes unenclosed is a luxury that can only be afforded in a scheme that also has a full range of resources, including Pedal stops, enclosed in at least two boxes. In smaller jobs the entire organ should be under expression, although sometimes circumstances dictate otherwise, for example where the Great must be placed forward of the Swell. In very large jobs it is good to have tones of similar character enclosed and unenclosed so that each class of tone can be used in its full range of expressive beauty. The best enclosure is masonry. Hollow brick faced with cement is the preferred construction and this points out the advantage of organ chambers in some situations. If an organ is primarily used for accompaniment where dynamic control and atmospheric, ethereal effects are of utmost importance, a properly designed and located chamber is ideal. An enchambered organ is as different from an encased free-standing one as a piano is from a harpsichord. Each has its advantages and each must be designed differently. The enchambered organ requires a stoplist emphasizing stops scaled and voiced for exceptional projection and carrying power, higher wind pressure, and a layout taking maximum advantage of the opening and preventing echoes within the chamber. In recent years chambers have been thoughtlessly despised. It is time to recognize their value as a means of increasing the range of musical options offered by the organ.

Dynamic Control

The symphonic organ must provide the organist with three distinct types of dynamic control: continuous, discrete-terraced, and sudden. These are all qualities common to the symphony orchestra, but often illusive on the organ. The continuous dynamic is achieved on the organ only through the use of the expression box and shades. A good expression box when fully open should not rob the pipes of clear projection and presence to any great degree, but when closed should reduce loudness from at least ff to p. To achieve this, a box must be reasonably sound proof with adequate density to control leakage of bass and must be well sealed when closed: Gaps are anathema to good expression box control. The shades cannot be too thick because their bulk will not permit a full use of the opening. Shades should be able to open 90 degrees. They must be fast acting and silent. Achieving smooth, continuous expression control is one of the greatest challenges in organ building.

To achieve a continuous dynamic range from fff to ppp we have developed a system of double expression, placing a box within a box. (See drawing.) The inner box is placed at the rear of the outer (main) box so that there is a large air space between the two sets of shades. When both sets of shades are closed, the space contained between them provides a very effective sound trap. We place the softest and most powerful sounds inside the inner box of the division. For example, a pair of ethereal strings and the Vox Humana; the high pressure chorus reeds and a mixture. A balanced expression pedal is provided at the console for each box. On large instruments a switching system allows the organist to select conveniently which shades are to be assigned to each balanced pedal. With the shades not quite fully open, the stops within the inner box are at a normal volume level to balance the rest of the division. With both sets of shades fully closed the soft stops in the inner box are reduced to near inaudibility and the chorus reeds are reduced to the level of color reeds. With all shades fully open, the chorus reeds and mixture are slightly louder than those of the Great. The Vox Humana usually has its own shades with a console switch to shift from pp to mf. There are many expressive possibilities with this system. For example, a crescendo may be started using the ethereal strings with both boxes closed, opening the inner box until the level is equal to the soft stops in the outer box, which are then added. The outer box is opened, adding stops in the normal manner while closing the inner box. The chorus reeds and mixture are drawn and the inner box reopened to complete the crescendo. This is done with ease after a bit of practice. During the installation of our organ in Washington, D.C. at St. Paul’s Church, music director Jeffrey Smith accompanied the Anglican choral service with nothing more than the Swell organ for over a month. It was the double box arrangement that made this possible.

The discrete-terraced dynamic requires having an adequate number of stops of similar or related tonal quality at different dynamic levels so that increased power is achieved in increments by adding stops. This effect is realized by hand registration, pistons, or a well-arranged crescendo pedal.

The third character of dynamic--sudden change--is usually done with manual shifts, second touch, very fast-acting expression shades, or a silent, fast and uniform stop action controlled by either the combination action or the Crescendo pedal and backed up by a steady, responsive wind system. Without this, a symphonic approach to organ playing is impossible. Clattery mechanism is annoying under any circumstances but especially so when sudden changes are required in the midst of a phrase, for example, to underscore an anthem or hymn text. We have introduced a device that adds another means of accent: the Sforzando coupler. It is a simple device wherein a coupler, for example Solo to Great, is made available through a momentary-touch toe lever. A fff combination can be set on the Solo and added to a ff combination on the Great at a climactic point with a brief touch of the toe to create a sforzando effect.

Wind System

There has been much discussion in recent decades about the virtue of flexible or “living” wind. If the wind supply were under the direct control of the player to be manipulated at will, there might be some point to argue. Since it is not, unsteady wind has no place in the symphonic organ. The whole point of the symphonic approach is to seek absolute control by the organist of all resources. So-called flexible wind is set in motion according to the design of the system and the demands being placed upon it. The organist can strive to achieve a reasonably pleasant effect, but he cannot have full control over the result. We believe in providing absolutely steady wind using a multiplicity of regulators, not only to make available different wind pressures, but to assure consistent response from all pipes under all playing conditions. Most chests are fed by at least two steps of regulation, each with spring control, so that the final regulator in the system does not have too much differential for which to compensate. A moving bass line should not upset the treble; intervals and chords should not de-tune when wind demand is high. It’s also important for the wind system to have more than adequate capacity to handle any demand and to have quick refill response so that staccato tutti chords will sound firm and full as they do in the orchestra. All too often, organs with great nobility of sustained tone turn into gasping caricatures when the forward motion of the music goes beyond their limits.

Another important wind system effect is a beautiful vibrato. We have developed a Variable Tremulant device, which allows the organist to control the speed of the beat from a balanced pedal at the console. We employ this normally on solo stops such as our Symphonic Flute. The normal, completely metronomic tremulant of the organ seems a bit unnatural when applied to lyrical passages. The Variable Tremulant allows the organist to simulate the more subtle vibrato used by first class instrumentalists and singers. The Vox Humana is also provided with a slow/fast tremulant switch, to fit both general and French Romantic repertoire.

Action

Speed and precision of both key and stop action are critical to the success of a symphonic organ. Key action must be lightning fast on both attack and release and respond uniformly from all keys regardless of the number of stops or couplers employed. Stop action must be fast and clean, i.e., without any hesitation or gulping on draw or release. Again, the entire action system must be silent. To meet these requirements we use electric-pneumatic action with an individual-valve windchest. (See illustration.) The expansion cell provides a cushioning effect similar to that of a note channel in a slider chest. It also allows placement of all action components near one another on the bottom board to reduce action channeling and increase speed.

The most important musical advantage of individual valves is to eliminate interdependence of pipes. With the exception of mixtures, where all pipes of a given note always speak together, we consider it a serious musical defect to place pipes on a common channel where the wind characteristics are different depending on the number of stops drawn and where there is a possibility of negative interaction within the channel. This is especially true, of course, with combinations of reeds and flues on the same channel and/or several large stops using copious wind. Each pipe should produce the same sound each time it is played no matter how many others are combined with it. As with flexible wind, the organist loses a degree of control over his instrument if random changes in pipe response can occur.

The most important reason for absolute uniformity of chest response under all conditions is the fact that pipes do not have the flexibility to adjust for variations in attack, wind supply, and release as do other wind instruments. A trumpet player, for example, can adjust attack, tone color, and release to an amazing degree of subtlety through precisely coordinated changes in breath, diaphragm, throat and mouth shape, tongue motion and position, embouchure, mouthpiece pressure, etc. In an organ, all of the analogous elements of control are set in place permanently by the voicer with the sole exceptions of wind regulator (diaphragm) and pipe valve (tongue motion). The pipe cannot change to accommodate variations in valve action and wind supply. As described before, wind supply cannot be controlled by the organist. This leaves the valve as the only means of control—and that control is limited even on the best mechanical actions. I submit that this element of control is actually a negative because variations in valve action, being different from the one experienced by the voicer, will be more likely to degrade pipe speech than to enhance it. If the key touch can affect attack and release but not all the other elements of tone production, then it follows that the organist is placed in the position of devoting his thought and energy toward avoiding ugly effects instead of concentrating on elements of performance that can be under precise and complete control. By maintaining absolute uniformity the performer knows what will happen every time a pipe is played.

Rather than searching for the elusive quality of touch control on the organ, we believe it is best to enhance speed of response and accuracy. The best way for an artist to achieve lyrical phrasing, clear articulation, and accent is through absolute control of timing. This is facilitated by keyboards with an articulated touch, providing a definite feel of the electric contact point, and an action that is immediately responsive both on attack and release. A sensitive player can then realize the most intricate and subtle musical ideas on what is essentially a large machine. The more the mechanism gets in the way of performance, forcing certain techniques, the less artistic freedom one has and the further the organ strays from the mainstream of instrumental and vocal music.

Flexible Control

We seldom acknowledge that the organist assumes the roles of orchestrator, conductor and instrumentalist—a daunting task to say the least. In effect, he is given nothing more than the kind of three-stave sketch that a composer might give to an orchestrator. The decisions an organist must make about registration are directly analogous to the orchestrator deciding on instrumentation, doubling, voice leading, chordal balance, etc. Since the organ is really a collection of instruments, the organist also has the conductor’s job of balancing the dynamic levels of individual sounds, accompaniments, inner voices of ensembles, counter melodies, and so on. As an instrumentalist he must have virtuoso keyboard technique. To achieve all of this requires great flexibility of control. The temptation is to load the console with a bristling array of playing aids. However, it is easy to pass the point where complexity becomes self-defeating. Here are some of the guidelines we use in designing consoles. First, the console must be comfortable. Dimensions should be standard and then, as far as possible, adjustable to conform to different organists. In addition to the adjustable bench, we have on several occasions provided adjustable-height pedalboards. We use a radiating and concave pedalboard and also non-inclined manual keys on the theory that when changing from one keyboard to another it is important that they be uniform. Controls must be placed in positions that are easy to see, memorize and reach. The combination action should be as flexible as possible providing the organist the opportunity to assign groups of stops to a piston at will. For example, on our combination action with the Range feature the organist can, while seated at the console, change divisional pistons into generals and vice-versa, assign pedal stops to a manual division, rearrange reversibles, etc. Multiple memories, of course, are now standard and of great value.

In addition to the multiple, assignable expression boxes, Variable Tremulant, and Sforzando coupler mentioned elsewhere, we like to include three special Pedal accessories on larger instruments. The first is a coupler bringing the Pedal to the Choir to facilitate fast pedal passages in transcriptions of orchestral accompaniments. The second is a Pedal Divide which silences the Pedal couplers in the low notes and silences the pedal stops in the upper notes. This allows the simultaneous playing of bass and solo lines on the pedalboard. The third is Pizzicato Bass, with a momentary-touch relay activating pipes of the Pedal Double Open Wood at 8¢ pitch. This provides a clear, pointed attack to the bass line reminiscent of divisi arco/pizzicato double bass writing for orchestra. This effect has been very useful in articulating bass lines, which on the organ are otherwise clouded rhythmically. The octave note is hardly noticeable, but the increase in buoyancy of the pedal line is quite amazing.

The most valuable and perhaps most controversial flexibility device is unification (extension). Certainly nothing other than tracker action has caused more argument over the last 50 years. The individual valve system obviously makes unification both simple and economical. Unification offers several musical advantages as we will see, but there are great dangers as well and it is most unfortunate that it has been so misused that some cannot see any of its advantages. We employ unification in symphonic organs, large and small, wherever a positive musical advantage can be achieved. Unification is, after all, merely coupling of individual stops rather than entire divisions. Whereas coupling is generally accepted, unification is not despite the fact that coupling of individual stops can offer a far more artistic result.

Perhaps the most interesting use of the unification is in creating new sounds. For example, to produce the stunning orchestral effect of trombones, tenor tubas, or horns playing in unison, we developed the Tuben (III) stop. This converts a chorus of 16’, 8’, 4’ tubas or trumpets into a unison ensemble by bringing the 4’ stop down an octave, the 16’ stop up an octave, and combining these with the 8’ stop. The three tones of slightly different scale but similar character create a most appealing unison effect and can be further combined with other stops of similar color at 8’ pitch. We have done the same with 16’, 8’ and 4’ Clarinet stops creating unison ensemble Clarinet tone, a common orchestrator’s device and most valuable to the organist for accompaniment and improvisation.

A traditional use of unification is in pedal borrowing from the manuals. We use this device extensively based on observation that one of the most difficult tasks facing an organist is finding a bass of suitable volume and color. We sometimes also borrow stops from one manual to another so that a stop may be used without tying up another manual with a coupler. A common application is transferring the Choir Clarinet to the Great so that it may be played against the Choir mutations. In some cases we derive an entire third manual on a moderate size organ from stops of the Great and Swell. This manual may either contain solo stops selected from both of the other manuals or a combination of solo stops from one manual and a secondary chorus from the other. A recent example is at Spring Valley United Methodist Church, Dallas, Texas. We occasionally extend stops—commonly downward to 16’ in the manuals and occasionally upward. Stops so treated must not be considered substitutes for primary chorus material. In other words, the organ must stand on its own as a completely straight design before any unification is employed. Stops extended upward must have a character of tone such that if a straight stop were to be employed, the scale would be the same or nearly so. Thus, extensions of string stops are much more likely to be successful than extensions of diapason stops.

Unification should not replace the ensemble of straight voices; it should simply make them available in different ways. If a stop can be useful also in another place or at another pitch and if this does not compromise the integrity of the organ’s design then we believe it is wrong not to include the unification. Failure to do so limits the organist’s musical options. The real point of the straight organ design concept is having all of the necessary independent voices even if one must give up some attractive ones to assure good ensemble. Once this is achieved, there is nothing wrong with making the voices you have do double or triple duty. It is interesting to note that in organs of a century ago a solo stop might be contrived through the use of couplers. A stop name would appear on a combination piston, the function of which was to draw a stop, a unison-off coupler, and an octave coupler thus making a 16’ reed, for example, available at 8’ as a solo stop. One can conclude that the earlier builders were not against unification, they simply did not have the practical means to do it. Unification and other devices to enhance flexibility need not be used by organists who do not like them, but to leave them out of the specification is to deprive others the full use of the costly resources the organ offers. Players of other instruments are always searching for ease of control so that their energy can be concentrated on musicianship. Organists might be a happier lot by doing the same instead of idolizing the organ’s ancient limitations.

Conclusion

We may be entering the greatest era in the fascinating life of the organ. The improvement in substitute electronic instruments has released the organ industry from the burden of making cheap pipe organs for customers with low expectations. Builders are working more and more for those with cultivated taste who appreciate an artistic approach to the craft. Organs are seldom purchased as a piece of church equipment as they were in days past. Now there is a place for all types of high quality pipe organs from antique reproductions to historically informed eclectic schemes to modern symphonic instruments. If the organ is to progress musically, it will be through the further development of its expressive—symphonic—qualities and the realization that the organ is a wind instrument ensemble with great potential, not merely a sometimes-awkward member of the early keyboard family.

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.

                  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.

The Reddel Memorial Organ at Valparaiso University: the first 30 years

As plans were being made in the middle 1950s for the
construction of a new chapel on the campus of Valparaiso University, the
administration was determined to provide an organ suitable to the size of the
building and of a  character to
carry forward the tradition of fine Lutheran church music already
style="mso-spacerun: yes">  established at the university. Dr. 0.
P. Kretzmann, university president; Dr. 
Theodore Hoelty-Nickel, head of the music department; and Dr. Heinrich
Fleischer, university organist, conferred with Dr. Paul Bunjes. The chapel
building, modern in dress but traditional in its long nave, elevated chancel,
and high ceiling, was originally conceived with a bridge across the nave on
which the organ would be placed, but saner counsel prevailed and the organ was
placed in the rear gallery.

In the 1950s the tracker revival was still some years in the
future. Tonal designs in the 50s usually included independent principal
choruses in each division, with the addition of some Romantic stops; voicing
was clearer and more forthright than that of Romantic organs. But electric key
and stop action was still the norm, and free-standing pipework was advocated.
Valparaiso University turned first to one of the preeminent organ builders in
this so-called "American Classic" style, Walter Holtkamp. Disputes
about tonal design and architectural features resulted in awarding the contract
to another builder, also known for his own particular brand of American Classic
organs: Herman Schlicker, of Buffalo, New York. The organ, designed by Dr. Bunjes
in collaboration with Mr. Schlicker, was completed and installed in the summer
of 1959. The dedication of both chapel and organ occurred on September 27 of
that year; E. Power Biggs played the opening recital to an overflow audience.

The principal donor for the organ was the Reddel family, of
St. Joseph, Michigan, and the instrument has since been known as the Fred and
Ella Reddel Memorial Organ. Originally planned as an instrument of 4 manuals
and 101 ranks of pipes, including an antiphonal organ in the chancel, the organ
at its dedication consisted of only 67 ranks and no antiphonal division. Over
the ensuing years, other donors, notably Kenneth Merrill of South Bend,
Indiana, and the Gaertner family of Farmington, Michigan, enabled a few
additional ranks to be added. The organ did not reach its planned size,
however, until the major renovation of 1995. The idea of an antiphonal division
was abandoned. However, the Valparaiso organ is an instrument of luxurious
size, allowing the player a widely varied palette of tonal colors. And even
more important, the designer and builder achieved the unity of character and
blend of stops that are the hallmark of the best organs.

In its first thirty years, the Reddel organ was host to many
of the world's leading organists. And generations of students, their parents,
faculty, and visitors have experienced the dimension that the Reddel organ has
added to Sunday and daily worship.

Behind the scenes of the organ renovation

"The organ should have sounded better," we all
thought that balmy fall afternoon during our guest organist's recital. The
playing was superb, but in spite of the fact that the organ was freshly tuned,
it was becoming clear, especially to some of our alumni present in the audience
that day, that the organ's voice was showing signs of age. One particularly
devoted alumnus, Michael Friesen, 
was thoughtful enough to bring this to the attention of the president of
the University. Likewise, in his typically efficient manner, Dr. Harre asked
the organ faculty to look into the matter. Prof. Gehring, Eifrig, Bernthal and
myself recommended that two consultants be brought to campus to evaluate the
organ's condition. Jack Bethards, president of Schoenstein Organs in
California, and Lynn Dobson, who later was hired to do the work, both announced
that the organ was in need of serious attention. Because of heavy use during
the school year, mechanically speaking the organ had aged three to four times
faster than a normal church organ. Tonally, pipes had become dirty and had
fallen off speech. Visually, the organ was in need of a good cleaning. Finally,
with the development of technology in the last decade, it would improve the organ's
usefulness and flexibility to update its systems.

The latter issue was the easiest to deal with. Solid State
Logic was asked to design the new relay system and combination action and
provide MIDI and playback capabilities for the organ.

Mechanical issues were also relatively straightforward. The
swell boxes had never worked properly, so the very latest, state-of-the-art
Peterson motors were installed. An elegant new console was built, copied after
the old one. While the organ was disassembled, it seemed financially prudent to
restore all the leather.

The tonal nature of the organ was doubtless the most
delicate issue to deal with and the one which required the longest
deliberation. Extra funds had become available to complete the organ, but we
also needed to consider what voicing could be done on the Schlicker pipes. Our
first priority was to keep the original nature of the organ intact. Here was an
excellent example (and one of the largest) of Herman Schlicker's innovative
work. All of the original scales (save for slight modifications to the the 8';
and 4'; principals on the Great) remained untouched. Selective voicing was done
to the flue pipes, not to change the nature of their tone, but rather to give
it more bloom in the chapel. Reeds were cleaned thoroughly and new tongues were
inserted in many, thus improving speech and tonal production.

A related concern was the organ specification. In 1959, the
funds did not exist to build the fourth manual. A Brustwerk and selected stops
from the other three manuals and pedal were left off. The committee thought
that since the essence of the original Brustwerk stops existed elsewhere on the
organ, and that several other stops, such as a two-rank celeste at 4'; pitch,
and two 4'; regals would not be as useful, we recommended some modifications be
made. There seemed to be a need for more 8'; pitch and string tone on the
organ, which caused us to add two 8'; principals (Positiv and Solo) and a
Salicional in the Swell and strings in the Solo. The battery of reeds in the
Great were completed as planned, but new reed colors were added to the other
divisions--a French Chalumeau, Vox Humana, Clarinet and English-style Trumpet.
Since it was clear that the new fourth manual would not be a Brustwerk and, in
fact, would include a set of strings, the decision was made to enclose the
stops and include Harmonic Flutes 8'; and 4'; and 4'; Principal. A cornet was
mounted on top of the box. A Schreipfeife (13/5'; and 11/7';) which was on the
original Bunjes specification, was installed on the Swell. Electronic 32's
would prove much more economical than the 12 wood pipes called for in 1959.

The organ was re-dedicated in a liturgy on Sept. 15, 1996.
John Scott, Organist/Master of Choirs of St. Paul's Cathedral, London played
the afternoon recital.

The process of restoration and enlargment

The approach of 1985, the Bach tricentennial, encouraged the
university organists to propose finishing the incomplete Schlicker organ. Not
only did the instrument lack almost one-third of the original stoplist, but
twenty-five years of constant use with only minimal repairs had left the organ
in need of major rehabilitation. The university, however, had other capital
projects underway; no large donor could be courted for the organ project. That
would wait for another decade.

The program for 1985, however, was the basis on which the
1995 project was conceived. By the mid-eighties the university organists had a
quarter-century of experiencing the Schlicker organ in the acoustics and
worship programs of the chapel.

The chests of most divisions were set up to receive the
prepared-for ranks, but there were neither chests for the Brustwerk division, nor
did Schlicker or Bunjes have any idea where such a division would be located.
There was also the need for larger sounds, not the miniatures of the specified
Brustwerk.

In 1985 Professors Gehring and Eifrig proposed an
alternative to the Brustwerk, a division that was not an independent chorus of
stops but rather a supplement to the Great. Not wanting to violate the
Bunjes/Schlicker concept, the university organists called this "the Cantus
Firmus Division," with additional horizontal trumpets and a set of
Principals to which the other divisions could be coupled. Such a plan would
enable the organist to lead the singing of 1500 voices in "packed
house" worship, soloing out hymn melodies above full organ accompaniment.
The 1985 plan waited for a later project, and the Bach year was celebrated on
the incomplete Schlicker organ.

By the 1990s Valparaiso University had attended to the
several building projects that had earlier taken precedence over the organ
rehabilitation and completion of the center for the arts. Now a new
administration was in a position to let an arts building represent its
accomplishments. Planning such a building for the music department of necessity
included plans for organ performance and instruction. At an early stage of
conceptual planning thought was given to a moderately large organ for a concert
hall. Budgetary restrictions as well as recognition that the Schlicker in the
chapel would always be the locus of organ performance left the concert hall and
its instrument out of the concepts for the Valparaiso University Center for the
Arts. In that center, dedicated in 1995, practice rooms for four organs were
provided and the Bauer Organ and Choral Room gave the Schlicker teaching organ
a happy environment for teaching, rehearsals, and small recitals or master
classes.

Martin Jean's appointment as University Organist coincided
with planning and construction of the arts center. The chair of the music
department and Jean reminded the university administration and the public that
the organ at the chapel is very much a component of the arts center as well as
a prominent voice for the musical arts in Lutheran worship. A turning point in
this campaign occurred when the Vice-President for Finance understood that the
Schlicker organ, suffering twenty-five years of neglect, was not serving
students well in their organ education. Her appreciation of this fact set in
motion the renovation, completion, and expansion of the Schlicker/Bunjes organ.

Funded by the Vice-President's office, the organists and chapel
staff of the university first drew up a list of builders from whom to solicit
interest in the project. Those interested were asked to state their
expectations for the renovation/completion, proposing a specification that
would modify the original Bunjes stoplist while respecting the Schlicker
character of the existing instrument. The organists and chapel staff
recommended that the Dobson Organ Company be contracted to refurbish and
complete the chapel organ. The University Office of Institutional Advancement,
while engaged already in a major capital funding drive, undertook to secure the
funds needed by the project. The Eickhoff family were generous supporters of
the almost half-million dollar capital investment.

Teaching organ students on the renovated Reddel Memorial Organ

It has indeed been a joy to teach organ students on the
Reddel Memorial Organ at the Chapel of the Resurrection. The clarity of the
ensemble, the presence in the room of individual stops, and the color and
balance afforded by the completion of the organ have been noticeable to members
of the campus community and visitors alike.

For students, the renovated organ offers a greater tonal
palette from which to choose registrations. The addition of the 16'; and 4';
chorus reeds on the Great increased the brightness and gravity of this
division; the extension of the 16'; Fagott from the Great into the Pedal and
the addition of an independent 8'; 
Trompette in the Pedal increased flexibility in this division. Various
divisions have been "filled out" by adding ranks "prepared
for" but not included in the original construction. Thanks to the addition
of a 13/5'; Großterz on the Great, II Schreipfeife on the Swell, and mounted
Cornet on the Solo we now have the luxury of Cornet combinations available on
all four manuals. The Pedal division now includes a 51/3'; Quinte (from the
16'; overtone series) and an 8'; Flötenbass for more versatility. The new
Solo division, which is enclosed, has greatly expanded the tonal possibilities
of the overall instrument. In addition to providing new colors available as
solo stops--8'; Harmonic Flute, large-scale Cornet, Clarinet, and Trumpet--the
Solo division augments the resources for playing 19th and 20th-century organ
literature. Other additions have made it possible to register organ music of
certain composers or schools more effectively. For instance, the addition of an
8'; Principal on the Positiv and 8'; Vox Humana on the Swell has greatly
enhanced the registration of Franck's organ music. The French 8'; Chalumeau on
the Positiv has likewise enhanced the playing of French Baroque music.

The sophisticated technology now available has made it more
convenient to store and retrieve registrations used by a variety of students.
Solid State Logic offers the capability of storing 40 general registration
combinations on each of 256 memory levels. The MIDI technology allows students
to record music which they are studying for playback in "real time."
Also, the Positiv, Great, Solo, and Pedal have two MIDI channels available
which can play sounds from a MIDI synthesizer, thus adding to the tonal
resources of the organ.

Organ students at Valparaiso University study church music,
particularly service-playing, which includes the playing of hymns,
congregational songs, liturgical service music, and accompaniment of choral
music. All of these areas have been positively impacted by the availability of
new tonal resources on the chapel organ. For instance, the accompaniment of
hymns at worship would formerly require the use of the Great principal chorus
including the mixture. This was due to the large acoustic space of the chapel
which needed to be filled with sound even when the chapel was not filled with
worshipers. After the renovation, the situation is much improved as the Great
Principals 8';, 4'; and 2'; provide sufficient clarity and strength to support
congregational singing. The tenor range of the ensemble is also more audible
and distinct in speech. The addition of the 8'; and 4'; Harmonic Flute (Solo)
and 8'; Holzflöte (Great) have proven very useful for choral
accompaniment.

Finally, the completion of this major renovation has sparked
new interest in the organ and organ music both from students on campus and from
students in elementary schools in the area.

The Isle of Man

From Peter Jones, the Offshore Organbuilder

This article is coming to you from the Isle of Man, an island some 30 miles long by about 14 miles wide, and sitting midway between Ireland and England. Its longest river--the Sulby--stretches for a full 10 miles or more, and Snaefell--the highest mountain--reaches a height of over 2,000 feet. Anyone with a world atlas and a magnifying glass to hand will have no trouble in locating the "Island," as those who live here often term it, off the west coast of England, facing Liverpool.

 

 

The Isle of Man may be little known in the wider world (or even on the "adjacent island" of England--we don't say "mainland," of course!) but like most places it does have its peculiar features which mark it out for those with special interests. It is an off-shore finance center, for example, with relatively low rates of tax. It is known for its motorcycle races (the "TT Races") which take place on the public roads--one of the largest (and arguably most dangerous) circuits of its kind in the world. For those who like unspoiled countryside to look at or walk over, and a quiet and relatively unhurried way of life, the Isle of Man is the place to be. It is an island of Fairies, one of the largest water-wheels you are ever likely to see, Celtic stone crosses and much more. Most important to me, and I hope of interest to readers, its small area is home to a surprising variety of some 50 or so pipe organs, and I am more than happy to have been the resident organ builder here for over 20 years.

For those of us with a fascination for the King of Instruments, there is much to be said about life here--too much for one article such as this--and rather than describe the organs as a whole in greater or lesser detail, I thought it might be better to describe some of the incidents which make the life of "the organ man" anything but tedious.

Looking back over the work undertaken in the recent past, I see one job which will be of interest to the great majority of organ players, from the professional recitalist to the home enthusiast who plays only for his own enjoyment. I refer to an ambition which attracts so many organists, and which eludes all but a few--the luxury of a real pipe organ in one's own home.

How many have investigated this possibility, only to find that the cost (and sometimes the space) involved ensures that the pipe dream remains just that? True, there is the electronic substitute--smaller and cheaper, with a great variety of Golden Tones of one kind or another--and then again the organ in church is usually available to the serious player--albeit not so attractive in the winter, nor so convenient for that odd 30 minutes practice at the end of the day. But for those badly infected by the organ bug, the unfortunates with an acute case of "organitis," there can never be any hope of a cure until they can see for themselves those gleaming ranks of metal and wooden pipes and the console with its several keyboards, waiting in the music room for their sole use!

So it was with The Reverend Alec Smith. His love of the organ had actually led him to start an apprenticeship in organ building as a young man, but he quickly saw the light, heard the call, and became an ordained priest in the Church of England. At that time, he assembled a worthy (if somewhat ungainly) collection of pipes, old keyboards, bits of mechanism, etc., into a Frankenstein creation which crouched in the corner of one of the large rooms of the vicarage in his country parish in England. This creation was a credit to its owner, but more than a little ponderous for anything other than a large house (preferably not your own) with plenty of spare rooms. When, in the fullness of time, Alec became an army chaplain, and he and his wife Jean were inevitably posted abroad, the organ was dispersed, almost all of it never to be seen again.

On retirement from the army, Alec settled in the Isle of Man and became Organ Advisor to the Diocese. It was now that the organ-building bug, which had lain dormant for so many years, was re-awakened, and the idea of a house organ was again proposed. There were, of course, several problems. The usual ones--centered around lack of space and finances--were, quite rightly, pointed out by Jean, and in any case there was a seemingly adequate 2-manual electronic, with its equally large speaker cabinet, already taking up far too much room in their small cottage in the Manx countryside. Jean correctly pointed out that it was more room they needed, not a pipe organ!

In a attempt to save some space, and acting on the advice of the local music shop, new and much smaller speakers were fitted to the electronic by an "expert" from Douglas, the Island's capital. After a day spent fitting the new speakers into the ceiling (with the novel use of a screwdriver to create some suitable holes in the plaster), the expert switched on, at which point there was an impressive bang followed by an ominous burning smell. It seemed, on later examination, that the amplifiers (intended to power two large speaker banks in a church setting) had seen the modern speakers as a virtual short circuit in electrical terms, with the inevitable result. The expert withdrew, promising to "work something out." I believe he left the Island, and, in any case, was never seen again. The electronic was no longer adequate. It was dead.

At this point, a further discussion took place on the subject of a new pipe organ, and Jean was persuaded, but only agreed on one seemingly-impossible condition: aside from the console, the new organ must not project into the room any further than the line of the first ceiling beam (some 14≤ from the end wall). Since there was no possibility of siting anything behind the walls (three of them being external, and the fourth taken up with the fireplace) the situation appeared hopeless, and it was at this point that Alec called me in.

Impossible situations regarding space are a challenge to the organ builder. More than one has succumbed to the temptation to push too-large an organ into too-small a space, with disastrous results, and I have seen the consequences of several of these unhappy situations. In one such case, an instrument was built in which the Great and Choir (mounted one above the other and in front of the Pedal pipework) "speak" into a solid masonry wall some 3 feet thick. Tuning/maintenance of such an organ is difficult if not impossible, and a warning to any organ designer. Alec's requirement was for the cheapest possible instrument, with a fair selection of stops over two manuals and pedals, all within a depth of 14≤. It had to fit into one small room of a cottage which has only three rooms on the ground floor (the other two being the kitchen and porch) and it must not be a monster from the tuning/maintenance standpoint.

There was space for only two or three sets of pipes, but Alec stated from the outset that, "I want more than three wheels on my car," so we were obviously looking to something other than mechanical action with two or three stops. This need to make the most of the available pipework suggested an "extension organ" of some sort. This, and the restrictions of the site, dictated electric action, and financial considerations suggested the simple mechanism as shown in the sketch. The question of electric versus mechanical action is one of those subjects likely to provoke strong opinions both for and against. In my view, each system has its merits and I am happy to work with either, but when a client requests more stops than the room or budget will allow, the obvious way forward is for a stoplist extended from a small number of ranks, and this means an electric mechanism. The design shown, if correctly made, is reliable, very quick (giving good repetition) and quiet. Incorrectly handled, it is none of these things, and has thereby acquired a poor reputation in some circles. With sufficient funds, and more space, an electro-pneumatic action would have been more sophisticated, but with enough care taken in its design and construction, direct electric action (as shown) is almost as good.

Some readers may be unfamiliar with the idea of an "extension" organ. This is an instrument in which a set, or "rank," of pipes is available to be played at more than one pitch. For example, a set of flute pipes could be played at 8' pitch (via a console stop labeled, say, Stopt Diapason 8') and the same set could also be available at 4' pitch (via a console stop labeled Flute 4') or at 16'  pitch (in which case the console stop might be labeled Bourdon 16') and so on. Clearly, the idea has its uses and abuses, as in the case of the 2-manual and pedal organ in which every console stop was actually taken from a single rank of Dulciana pipes!

The final stoplist is one which I have used successfully on various occasions. It is based on three ranks representing the three main tone-colors of the organ:  Diapason, Flute and String. Each of the three ranks consists of 73 pipes, and are listed below as:

Rank A/ Open Diapason, running from C13,

Rank B/ Stopt Diapason, running from C1, and

Rank C/ Salicional, running from C13.

In addition there are 12 stopped Quint pipes (shown below as "Q") running from G8 (at 8' pitch) for the pedal 16' stop (see later).

(Reed tone was not included, as it is difficult to have conventional reeds sufficiently quiet for such a small setting. In any case, there was no space available.)

Note that the Open Diapason is of small scale, and this made it much more suitable, for our purpose, than the more usual scaling of such a stop. When selecting second-hand pipes for a home extension organ, a Principal would be the first choice  to provide the Open Diapason--Principal--Fifteenth "stops," as they appear on the console, and I have even known a Gamba to make a very acceptable open metal extension rank, once it had been re-scaled and re-voiced. Ideally, where finances are not a limiting factor, new pipes should be made for all ranks, so that their scaling can be suited to the room and stoplist.

If an "extension" scheme is to work, musically, it is important to avoid the temptation of too many stops from too few pipes. I know of one organ with the stops simply repeated on each keyboard, and though this gives maximum flexibility, it is very confusing from the player's point of view, and the instrument as a whole is strangely bland and characterless. The three sets of pipes for Alec's organ were made available at different pitches, under the guise of different stop names, to make registration more straightforward from the player's point of view. In this way, some 15 speaking stops are available to the organist, instead of three which would result from the use of mechanical action.

The specification shown has only one stop (the Stopt Diapason) actually repeated on each manual. This is because it is so frequently used, and blends with the other two ranks at 8' pitch.  None of the other manual stops are repeats, and they have been arranged so as to discourage the use of the same rank at only one octave apart. (E.g.,  the Open Diapason 8' is intended to be used with the Salicet 4', or the Flute 4', not the Principal 4', as you might expect.) Using the stops of an extension organ in this way reduces or (more usually) eliminates the well-known "missing note" problem, which occurs when one strand of the music runs across another, and both need a pipe from the same rank, albeit from different extended "stops." If, for instance, the Stopt Diapason 8' and Flute 4' are drawn on the same manual and key C25 is held down, the pipes heard, as counted from the flute rank, will be C25 and C37. Now add manual key C13, which will sound pipes C13 and C25 (which is already playing from key C25). In this example a pipe at the pitch of C25 should appear twice, but actually appears only once. The missing note will be most obvious if either of the two manual keys is held down while the other is repeated.

One of the most important criticisms to be levelled at an extension scheme is this problem of missing notes, which can lead to a lack of clarity. For all practical purposes, this drawback can be completely overcome by a combination of the organ builder (in preparing a modest stoplist) and the player (in thoughtful use of the instrument, so that the smallest number of stops is drawn at any one time, preferably from different ranks, or at least from ranks separated by more than one octave). In actual practice, this kind of stop selection becomes automatic to the organist who realizes the limitations of the instrument.

Another important factor in the success of this type of organ is the regulation of volume and tone quality of the pipes within a stop, and also the regulation of the stops in relation to each other. Each stop is regulated with a very gradual crescendo from bass to treble. This requires subtle handling, but when correctly carried out results in a clear ensemble in which the treble parts can be heard above the tenor and bass.

The ranks themselves are regulated with much less distinction in power than would usually be the case, so that equivalent pipes of the Stopt Diapason are similar in volume to those of the Open Diapason, and the Salicional, while quieter, is not far behind. This results in much less contrast in power among the 8' stops and this is a compromise, of course, though you still have variety of tone. The blend between ranks played at different pitches is much better than if they are regulated in a conventional manner, with the Open Diapason much louder than the Stopt Diapason and Salicional distinctly quieter. In an instrument such as this, contrast in power is created more by contrasting combinations of stops than between the ranks themselves. Regulating the ranks as if they were separate stops (a mistake often found in both church and house extension organs) results in the Open Diapason and Principal obliterating everything else, while the Fifteenth screams. 

I have used the specification shown several times, including my own house organ, and find it to behave very much as a 'straight' instrument would. I seldom use the couplers, though there are occasions when they become necessary. While it requires thoughtful registration to get the best from an extension organ, a scheme such as this, with a small number of stops, arranged so as to discourage the use of the same rank in two stops separated by only one octave, is very successful.

To cut down costs, Alec agreed to the use of his old electronic as a console, and also to the use of any other second-hand parts which could be obtained. He was also interested and able to lend a hand in the actual construction, when his earlier experiences in organ building were a great asset. The need to keep within 14≤ maximum depth was easily dealt with, by taking up the entire width of the room, side-to-side.

Knowing the number and range of the ranks and the space available, the first step, in a job such as this, is to measure the pipework, in order to see how best to arrange the pipes, and, indeed, if they will fit in at all!

Metal pipes need to be measured in height and in diameter, wooden ones in height only (including any stoppers). In practice, nearly all metal pipes run to a standard scaling (i.e., the rate at which the diameters reduce from note C1 through to the top pipe). Wooden pipes vary considerably, both in scaling (the internal width and depth) and in the thickness of the wood used, which in turn decides the external width and depth. There is also the question of the foot, which, in second-hand wooden pipes (and some new ones) can be bored well off-center. For these reasons it is best to make a paper template of the bottom of each wooden pipe, as described later.

I already had a small scale (i.e., relatively small diameter) Open Diapason rank, and a Salicional, both running form C13 (so the longest pipe in both sets was about 4' speaking length) and Alec located, from a friendly organ builder on the mainland, the Stopped Diapason pipes (running from C1) and a bundle of miscellaneous stoppered wooden pipes for the pedal Quint.

The necessary measurements were taken and noted down in the form of a table. I find it convenient to have a sheet of paper with the 12 notes C through to B in a column down the left-hand edge, followed by vertical columns headed "1--12" then "13--24" then "25--36" and so on, up to "73--84," placed from left to right across the page. This forms a table which will cover an 84-note rank, the biggest usually needed. (Note C85 is only necessary in the case of a rank which runs from 8' pitch to 2' pitch, where the organ has a manual key compass of 61 notes. This C85 pipe needs an additional square to itself.) Every square represents a pipe, and in each one can be written the length and diameter (if metal), together with other details such as size of a rackboard hole, and toe hole etc., which are also measured at this time.

Notice that only the Stopped Diapason rank has its bottom octave (in organ building terms, a "Stopped Bass") the largest pipe of which is, like the other two ranks, something over four feet long. The Salicional and Open Diapason share this bottom octave, as does the 16' pedal stop (the "Harmonic Bass") which produces an acceptable 16' substitute, in the first 12 notes of the pedalboard, by playing the Stopped Bass pipes with the appropriate Quint pipe (from a separate and therefore very soft, 12-note rank of wooden pipes). The resultant note (actually a low hum) which is created from a combination of any stop of 8' pitch and its quint is at 16' pitch. Admittedly, this is much softer than the two pipes actually sounding. The pedals from C13 up play the Stopped Bass again, and then the rest of the Stopt Diapason, thereby sounding at true 16' pitch. These compromises are necessary to reduce the size of the organ, and, if carefully carried out, are soon accepted by the player and listener, especially in a small room.

While there is no substitue for the soft, heavy, warm tone of a full-length Bourdon bass, I have asked many players (including several professionals) their opinion on this "resultant" 16' pedal stop. So far, no one has realized what he was playing until it was pointed out. They all accepted it as a pedal 16'  stop, like any other. The least convincing notes in the bottom octave are, predictably, the smallest three or four. If there is room for full-length pipes down to, say, F#7, so much the better.

It is worth noting that a quinted 16'  effect which uses the pipes of the Stopt Diapason rank only is almost always a failure, because the quint will be too loud. If you have no room for the extra Quint pipes, it is better to use the 8' octave of the Stopt Bass on its own (from pedal keys C1 to B12) before completing the pedal compass by repeating the Stopt Bass followed by the rest of the Stopt Diapason. Another possibility worth considering is a 16' bottom octave in free reeds.

Full-size card or paper templates are needed to represent the metal pipes, as seen from above. It is not normally necessary to make these for every pipe, as different stops usually reduce in diameter, note for note, to a more or less standard pattern. If this pattern is known, the set of templates need cover only the range of diameters from the fattest metal pipe in the organ (in this case C13 of the Open Diapason) down to the minimum spacing dictated by the pipe-valve mechanism. (As direct electric action was being used and the smallest magnets were 3/4≤ wide, with pipes placed directly above the valves, minimum pipe spacing = 3/4≤ + 1/8≤ clearance [= 7/8≤] no matter how small the pipes.)

Like most organ builders, I have a set of these circular templates for general use, so templates for the metal pipes were already at hand, but the wooden pipes had to have paper templates individually made to show their exact shape and the center of the pipe feet. Such a template is made by taking an over-sized piece of paper, drawing on it a circle which equals the diameter of the pipe foot, cutting this out, and sliding the paper up under the pipe and creasing around the four sides. Once the paper is removed and trimmed to size, the original circle can be taped back into place, resulting in an accurate template.

Alec's wooden Stopt Diapason (reputedly by the well-known Victorian organ builder, William Hill) was over 100 years old, and may have been in more than one organ during its lifetime. Its mouths were rather high, which made the tone breathy, and some of the pipes had been mitred, or were cut too short, possibly where they had been in a crowded swell box. But it was basically sound and we went on the basis that it could be made acceptable by repairs, lowering the mouths and re-voicing. The Salicional and Open Diapason ranks were also Victorian, from a local Methodist church. Again, they were not perfectly scaled or voiced for a house  organ, but were basically well-made and capable of re-voicing. All the pipes were measured, and with the tables of measurements and templates to hand, and a given space into which to fit the pipes and action, the process of "setting out" could begin.

An instrument with direct electric action enables the builder to arrange pipework in almost any pattern, within the limits of the room and the physical space taken up by the pipes themselves (or, in the case of the tiny treble notes, the size of their magnets and valves). My preferred system of setting out is slightly unusual, in that I like to place the taller pipes behind the smaller pipes, regardless of their rank. Most other builders would plant pipes in rows, each row being made up from pipes of the same rank.

Secondly, and in common with many of my colleagues, I prefer to plant pipes in "sides," i.e., pipe C1 on the extreme left of the organ, and C#2 on the right, working down to the treble pipes in the middle. In this way, all the pipes of the "C side" (C, D, E, F#, G#, A#) will be on the left, and those of the "C# side" (C#, D#, F, G, A, B) will be on the right.

These two underlying principles result in a pipe set-out which is visually attractive, compact, and which offers the greatest accessibility for tuning and maintenance. Admittedly, it does lead to some complications in the cabling patterns between the console and the magnets, but this is not an insurmountable problem. (In fact, the many cables for this organ were made up, wire by wire, by my school-boy workshop assistant, with no errors at all.)

Alec and I set out our templates on strips of white paper, as wide as Jean would permit, (the 14≤ maximum) and as long as the space available (i.e., the width of the room: 157≤ or just over 13 feet). After a day or two of pushing the templates around, and, bearing in mind the many details such as how the pipes could be best faced away from each other, the space to be allowed for rack pillars, cable registers, assembly screws and many other essentials beyond the scope of this account, we decided upon the ideal arrangement, with the pipes set out on three chests. The chests were placed one above the console, for the treble pipes, and one on each side at a lower level, for the bass pipes. The central chest was just under 13≤ from front to back, and the two other chests were only 9≤ wide. The whole organ would stand in the maximum ceiling height of 91≤ (barely over 71/2 feet). The actual planting pattern was so tight that every possible space has been used, given the limited width and length available. Even so, no pipes are crowded, and all of them have been accommodated. The fronts of the three chests were made from oak-veneered ply salvaged from the old speaker cabinet and console back of the electronic. Consequently, they matched the finish of the console exactly.

Admittedly, there was no room for any casework or building frame, and we had yet to solve the problem of space for the blower, wind pressure regulator, wind trunks, low voltage current supply and one or two other essentials, but these are minor obstacles to the true organ fanatic!

The actual construction of the instrument started with the chests--comprising the pipe ranks, toe boards, or top boards (on which the pipes stand) "wells"  (the sides and ends) and bottom boards. Details of each chest varied with the numbers of rows of pipes, but the sketches showing the basic mechanism will give a good idea of a typical chest in cross-section.

Strips of mdf (a sheet material available in 3/4≤ thickness) were cut for the top boards for each of the three chests, and the pipes centers were punched directly onto them, using the paper setouts, taped down, as a template. Based on these centers, the magnets, valves, pipe racks and the many other details of the mechanism can be marked out and fitted. Unfortunately, a detailed description of this procedure is beyond the scope of a general article such as this. While the basis of the mechanism is shown clearly in the sketch, there are a great many practical details which must be finalized in design and observed in manufacture, if this deceptively simple idea (drilling a hole, screwing a magnet and valve under it, and planting a pipe on top of it) is to be carried through to create a reliable musical instrument. Such a mass of information has not, to my knowledge, ever been written down, as it is essentially based on practical experience over the years. If any readers are interested in further practical details, it may be possible to describe some of the problems involved, and how they are overcome, in a future article, but only a practicing organbuilder can have all the necessary skills and knowledge to cope with every situation, and this makes it impossible to give a general "recipe" for building an organ.

The wind supply is provided by a small electric blower of course, but this one is unusual, in that it was passed on to Alec by an organ-building friend from the days of his original house organ. Indeed, it turned out to be the very same blower, which had returned to him, after an absence of 30 or more years! It proved to be an excellent machine, and very quiet when housed in a new silencing cabinet.

It was necessary to regulate the wind pressure to a value suitable for the pipes and their setting, and, of course, we had no space for traditional bellows. In a case such as this, I used my own design of wind pressure regulator (basically a hinged plate of 1/2≤ sheet material, "floating" over a rubbercloth diaphragm, and supporting some suitably-tensioned springs). Movement of the plate controls a valve which allows wind from the blower through to the chests. As the pipework makes a demand on the supply, the valve opens just far enough to maintain pressure to within 1/8≤ or less at peak demand. This is an acceptable degree of control, and only a very critical ear will notice the slight fall-off in power. Every builder has his favorite design for such a regulator (sometimes called a 'schwimmer' or, in my case, a 'compensator') and they all bear a strong family resemblance. Not all are equally effective, however, and some are prone, under adverse conditions, to fluttering (creating an effect like a very rapid Tremulant). Again, only experience of such devices can provide a way out of trouble, though there are some basic rules in compensator design.

The steady, regulated wind from the compensator is fed to the chest by a rather broad, but shallow, wind-trunk (made in mdf, like the blower box and compensator). This is fixed to the back wall, out of sight, behind the console.

With all the basic elements designed, there still remained the question of the 14≤ limit on width. Obviously, the blower box and compensator were too wide to keep within the limit, so it was decided to camouflage them, together with the circuit boards, transformer/rectifier unit, and other large components.

In the final design, the three chests were screwed to plates of 3/4≤ ply, previously fixed, in a true vertical position, to the rather uneven stone wall. The console was placed centrally, with the two outer chests (holding the bass pipes) low down on each side. The third chest (containing all the treble pipes) was fixed centrally on the wall, just behind and above the console's music desk. Two bookcases were made to fill completely the gap between the sides of the console and the side walls of the house. They were set rather further forward than would be usual, with a broad top which ran back to the wall behind, effectively disappearing under the side chests.

On the left of the console, the bookcase is a real one, with its top extending over the circuit boards and transformer/rectifier unit hidden behind. To the right of the console the seemingly identical bookcase is, in fact, a dummy. Its shelves and books are only about 11/4≤ deep. (One of the more bizarre scenes in the workshop was that of pushing large quantities of scrap books through the circular saw, leaving their spines and an inch or so of paper and cover. These truncated volumes look convincing when glued, side-by-side, onto the foreshortened bookcase back.) The space under the dummy bookcase top contains the blower box and compensator. The bookcases, blower box, compensator, etc., all sit on 3/4≤ ply panels which have been leveled onto the floor.

Once Alec had installed his real books and ornaments, the organ (while visually dominating such a small room, as it must) blended into its domestic setting beautifully, with a spectacular visual touch being provided by a trumpet-blowing angel, carved in oak, which had been salvaged from a local church altarpiece,

What of the finished product? Naturally, the instrument is a compromise--but then this is true of all but the largest organs. It is a pity, for instance, that there was no room for a swell box, or another rank, but it is a wise builder or player who knows when he has gone as far as space and finances will allow. The wooden Stopt Diapason rank had its top lips lowered, and was re-voiced to produce a charming, rather quaint sound, with none of the original's unattractive, breathy tone. The Open Diapason had to be softened to just short of dullness, and now adds considerable fullness and warmth. The Salicional has made an excellent quiet voice, and is also very useful in its other pitches, where it adds brightness without shrillness. This is most important in a small room, and it is worth noting that, the larger the room (up to cathedral proportions) the brighter and more cutting the treble pipework can, and must, be. But the opposite is true for a small space, where top notes can easily become uncomfortably piercing--hence the lack of Mixtures on small house organs with no swell boxes. Many visiting organists, both professional and amateur, have played Alec's instrument since its completion, and all have been pleasantly surprised by its resources and the fact it is possible to produce satisfying performances of both classical and romantic works, albeit with some ingenuity on the part of the player.

True, it would have been possible to install a "large" electronic with three or four manuals, a wide range of stops and artificial reverberation, and I can see the attraction of such an idea, especially for the player whose interest lies in large-scale, romantic works. But, I cannot imagine anything less convincing than the sound of pedal and manual reeds, with Diapasons and mixtures, echoing with a five-second reverberation, across a room some 16 feet long and 8 feet high. The sound of a small organ in a small room, with no reverberation at all, is an authentic one and has a special charm. Whether it be two or three ranks of pipes offered with mechanical action as two or three stops, or whether, as in this case, the ranks are extended to several "stops," the small domestic instrument has a sound and fascination all its own, and is capable of giving much pleasure, both visually and musically, over many years.

From the Organ Builder

Trying to find the "right" style in designing a
new organ seems harder today than ever. Rather than just following an
established, clearly defined model, we must choose from a wealth of information
that today, more than ever before, is accessible to us. One solution would be
to seek comfort in the relative safety of copying some beloved historical
instrument. While there is some debate as to how far that can be achieved, our
own attempts at this have not been failures in that they seem to be as close to
the model as any restored original. This route would result in an organ that is
pleasant to look at and renders the music of its own period authentically and
beautifully. The opposite extreme, I suppose, would be to attempt the creation
of a new style, throwing overboard much of what has spelled success in years
past. Whenever that has been done, however, the results have usually been the
more disappointing in their paucity as less tried and proven features are
incorporated.

At Middlesex School we wanted to create an organ that
renders music from a large range of musical styles in a pleasant and reasonably
authentic manner. We also wanted it to accompany the school congregation well.
The pleasant, quite traditional architecture of the chapel, obviously, provided
valuable clues. Last but not least we let the many historic organs we have come
to love inspire us. More blessed by this wealth of information than burdened by
it, we did what we normally do and designed an organ that is somewhat unique,
that belongs to its environment such as this school and its chapel. Informed
and mindful of its setting, yet independent and strong in its task of making
our lives richer through great music of a powerful tradition, it truly is the
Middlesex School organ.

The layout of the new organ follows the classical pattern of
the Great and Pedal divisions being placed in the upper, wider portion of the
case. The large wooden pipes of the Stopped Bass 16' are actually hung from the
organ's ceiling in the center of the upper case, above the central wallboard.
These two divisions share a symmetrical pair of windchests, which also
facilitates transmission of some of the larger pipes as well as the Trumpet
stop. We find that the savings in space--making the organ rather compact and
therefore projecting better--seem even more significant than the savings in
cost. Such transmissions require check valves, which could adversely affect
pipe speech in smaller pipes and reeds, which is why no small pipes are
transmitted. The Trumpet utilizes channel dividers that actually make check
valves unnecessary for this stop. The Swell division occupies the upper half of
the lower case. Even the full-length 8' stop belonging to this division found
room in the lower case, albeit with some difficulty. The key action is all
mechanical, while the stop action is electrical, allowing an extensive
combination action. The wind system employs a small "static"
reservoir, located near the blower in a storage room under the organ, and a
wedge bellows in the lower part of the organ as well as wooden ducts. We
attempt to give the organ a breathing quality, which we prefer to the rather
stern sound of an overly stable wind system. It is essential, of course, that
there be no audible blower noise.

The tonal palette contains a Plenum, vaguely reminiscent of
those by J. S. Bach's contemporary Gottfried Silbermann, a set of three reed
stops that echo classical French reeds, and a Dulciana that traces its ancestry
to Old New England. The gentle and colorful flute stops have common roots in
many fine historic organs. The casework is made from solid maple, painted in
two shades of white, and decorated with turned black walnut spindles serving as
Swell and pipe screens. The keydesk area is also from black walnut. The manual
compass is 58 notes C-a''', the keys have bone naturals and solid ebony
sharps. The 30-note pedalboard is concave-parallel.

The entire crew at The Noack Organ Company has enjoyed
designing and building this organ. Having hosted it for a year at our workshop
pending completion of the chapel renovation we were almost sad to part with it.
We are very grateful for the trust in our work and the valuable assistance by a
large number of people connected with this project. Besides the entire organ committee,
we must mention Mary-Sue Willie, former organ instructor; Deidra Ling,
headmistress; Jim Saltonstall, business manager; and Sarah Megan, head of the
Music Department of Middlesex School. We particularly enjoyed the cooperation
with Peter Sugar and the great staff of the firm of Ann Beha, Architects, of
Boston. The advice of Carl Rosenberg of Acentech, acoustical consultant, was
helpful, indeed, to provide a pleasant acoustical setting for the new organ.

From the Dedication Recitalist

It was a pleasure and honor to perform the dedication
recital on this new organ. Rarely is a new instrument so perfectly integrated
into an existing building; much sensitivity was shown by architects and
acousticians in planning the placement and design of this organ balcony, and
the organ perfectly ornaments the room both visually and acoustically. It is
also an educational bonus in a school setting for the organist's activities
(especially pedalwork) to be seen clearly by the student congregants. It's important
not to hide the organist!

Music for the dedication recital of an organ must be
carefully chosen; simple and complex, fast and slow, soft and loud, Baroque,
Romantic and modern works must balance in order to show the full range of the
instrument's capabilities. This recital program attempted to show the
considerable possibilities afforded by the new organ, but the instrument's full
versatility will only be revealed in the coming years. The recital included
works of Buxtehude, James Woodman, Mendelssohn, Pierre du Mage, Messiaen, and
Bach, and all fit the instrument splendidly.

The Great chorus is strong, well-balanced, and focused
without aggressiveness. The Trumpet can seem to have both a dark German or
bright French sound depending on what is added to it; alone, it can hold its
own either in solo or contrapuntal textures. The Chimney Flute is strongly
colored but without excessive chiff, making it very useful as an
accompanimental stop. The mutations are strong and of principal tone, resulting
in good blend with either the Trumpet or the chorus.

The Swell division is quite a bit more than its stoplist
might indicate. The full-compass Dulciana sounds as a gentle, small Principal
much like early nineteenth-century examples and blends with the full-bodied
Gedackt to provide a strong foundation for the upperwork. The Principal 4'
anchors the division, while the Mixture is not high-pitched; it is even a bit
lower than the Great mixture, thus producing a tightly-knit chorus sound that
complements the Great and adds intensity without extra brilliance. The Cremona,
rich in fundamental, can function both as a chorus and solo reed, while the
flutes are piquant and colorful.

The Pedal provides a useful palette of colors and strengths
to support the manual sound; the Posaune in particular blends in with the other
stops and adds both considerable fundamental and quick speech to the lowest
pitches.

The key action is crisp and light, just as sensitive to
nuances of release as attack. There seems to be a felicitous balance between
the heft of the key action and the spring of the pedal action, resulting in an
almost-miraculous ease of coordination between them for passages where all
parts move simultaneously. The electric stop action makes the organ seem bigger
as quick registration changes become possible, increasing the flexibility
considerably.

It has never been as important as now to provide the best
possible examples of the organ for young people to experience in formative ways
in school settings. This new organ sets an example that I hope will be emulated
over and over as Middlesex students go out into the world.

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:

Bass

8' Diapason Bass

4' Principal Bass

2' Fifteenth

Treble

8' Diapason Treble

4' Principal Treble

2' Octave Treble

[rebuilt by Mander]

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.
