Music City’s New Symphony Hall Organ
In its February 1982 issue, The Diapason published an article that challenged conventional wisdom. (See reprint of the article on pages 27–28 of this issue.) In it, Calvin Hampton made a convincing argument that an organ designed to be an instrument of the symphony orchestra must be radically different in many respects from a church organ or even a concert organ intended for solo use. A “normal” organ, even a fine one, could not pass his audition for symphony hall use. This really caught my attention. Since my background had included playing in and managing symphony orchestras, I was keenly aware of the uneasy relationship between orchestras and pipe organs. To managements, the organ was a headache. It used up too much space and too much money. Stagehands didn’t like the extra hassle of set-ups and working out quiet time for maintenance. Musicians didn’t like tuning to the organ or listening to its quinty mixtures and other thin, shrill sounds. Conductors never seemed satisfied with either the tone color or volume produced. Comments heard over and over again were: “I like that tone, can it be louder?” “Good balance, but I’d like a fuller, darker tone.” “Please(!)—keep with my beat!” The organist’s answers usually provoked frustrated and sometimes colorful comments about the inflexibility of the organ. The poor organist had even more problems than these: scarce rehearsal time, balance problems if the console was attached to the organ, poor sightlines if the console was on stage but too large or placed off in a corner.
The biggest problem of all was disappointment for the audience. The power of a modern symphony orchestra is so immense that most concert hall organs could not add to the drama of a fortissimo tutti. Against the gravity of the full orchestra, an ordinary organ can sound pathetically thin and upside down in balance, with trebles screaming out over the top of the ensemble. I had wondered for a long time why no one had attempted to solve all of these problems with an innovative approach. Calvin Hampton’s article gave me hope that someone would. About ten years later the tide began to turn. The musical issues were being addressed and many of them quite successfully. However, as a former instrumentalist and symphony manager, I thought that a more radical approach was needed.

Solving problems
Most of the behind-the-footlights practical problems can be solved by adopting an obvious, but, in some quarters, unpopular guideline: employ the fewest stops necessary to get the musical job done. This means an instrument that takes up less space, is less costly to purchase and more efficient to maintain. The case or chamber can be shallow for best tonal egress. Layout can be arranged for temperature—and thus tuning—stability; for example, all chorus work on one level, all reeds on one level. The console can be more compact, promoting sightlines and ease in setting and striking. The concept is easy enough to adopt, but what is that magic number of stops? What is the musical job to be done? How can we produce adequate power that will satisfy the audience?
First, it should be established that we are considering an instrument primarily for the Romantic and Modern repertoire. A properly equipped symphony hall should have one or two mechanical action stage organs to take care of the earlier repertoire. Previous experiments to include a “baroque” division with a small console as part of a large instrument have not been successful.
The primary use of the organ will be with orchestra. As a solo instrument, it might be used on occasion for choral accompaniment, silent movies as part of a pops series, and some special events. The solo organ recital has turned out to be a rarity in symphony halls. This is also true of other instrumental or vocal recitals. The reasons are simple: economics and scheduling.
If this musical job description is accurate, then an instrument in the size range proposed by Calvin Hampton (46 voices) would be ideal. Certainly any well-designed instrument of that size should also be able to render a very convincing recital program when needed. The key to a great performance is great tone, not great size.
If client and builder have the discipline to follow this Multum in Parvo plan rigorously, the question of tonal design becomes a matter of selecting stops that are absolutely essential and living without those that would be nice to have. Several classes of stops can be excluded with ease because they are duplicated in the symphony orchestra. Certainly there is no need for multiple strings and celestes or for orchestral reeds such as French Horn, English Horn, and Orchestral Oboe. The organ does not need items that would be considered necessities in a comprehensive church organ or in one specialized for some branch of the organ solo repertoire or for transcriptions.
What, then, are the elements that a symphony hall organ must have? Understanding what musical value the organ can add to the orchestra leads us to the answer. There are three characteristics of the organ that differentiate it very clearly from the orchestra. First, its frequency range is far greater. It can extend octaves below and above the orchestra. Extending the bass range has been the feature most appreciated by composers and orchestrators; however, increasing the treble range can be attractive, provided that it doesn’t get too loud! The second special characteristic of the organ is its unique tone—the diapason. This is a tone that cannot be produced by the orchestra and should, therefore, be the backbone of the organ when heard with the orchestra. The third element that should be most intriguing to composers is the organ’s ability to sustain indefinitely. This feature is most artistically displayed in connection with good expression boxes. A long, continuous diminuendo or crescendo can be most effective.

Four vital design points
Since there is a general understanding of basic organ tonal elements common to composers who write for orchestra as well as for the organ, a good symphony hall organ must include the minimum architecture of a normal three-manual traditional Romantic organ: diapason choruses and chorus reeds on each manual, representatives of stopped, open and harmonic flutes, a string with celeste, flute mutations, and the most common color reeds (Oboe, Clarinet, and Vox Humana). To make the organ capable of working in partnership with a modern symphony orchestra, the following tonal elements must be incorporated into this traditional scheme:
1. Profound Pedal. This is the most important element an organ can add to a symphony orchestra—bass one or two octaves below the double basses, bass tuba and contra bassoon. There must be at least one stop of such immense power that it will literally shake the floor. Stops of varying colors and dynamics with some under expressive control complete the Pedal.
2. Solo stops unique to the organ. These may be tones not found in the orchestra such as a diapason, stopped flute, and cornet or imitative stops that can be voiced at a power level not possible from their orchestral counterparts, such as solo harmonic flutes, strings, clarinets, and high pressure trumpets and trombas.
3. One soft stop capable of fading away to a whisper. Perhaps best in this role is a strongly tapered hybrid (or muted) stop.
4. An ensemble of exceptionally high power under expression. This cannot be raw power. It must be power with beauty, centered in the 8′ and 4′ range to give a sense of solidity and grandeur. Since symphony halls are generally drier acoustically than the typical organ and choral environment, it is even more important that this power be concentrated in the mid-frequency range and be of warm tonal character. The false sense of power created by excessive emphasis in high-pitched tones should be avoided. Orchestras don’t rely on a battery of piccolos for power, why should the organ? Piccolos can dominate an orchestra and so can mixtures, but that doesn’t make either effect beautiful. The kind of power needed comes from moderate to high wind pressures and stops voiced with rich harmonic content for good projection. Upperwork should be for tonal color rather than power. At least one diapason chorus should include a very high pitched mixture, a tone color unique to the organ, but it must not be loud. Eight-foot diapasons, chorus reeds, open flutes and strings should work together to create an ensemble capable of standing up to a full symphony orchestra. As someone who has sat in the midst of a symphonic brass section, I have a clear idea of the kind of power that is generated by trumpets, trombones and horns at fff. To compete without sounding shrill and forced requires high pressure diapasons and reeds, including a 32′ stop—all under expression to fit any situation.

Good tonal design must be supported by a mechanism that helps the organist solve all the performance problems mentioned above—an instrument that is as easy as possible to manage. The organ builder should employ every device at his command to give the organ musical flexibility so that it can take its place as an equal among the other instruments of the orchestra.

The Nashville project
We were given an opportunity to demonstrate the effectiveness of these ideas in our project for the Schermerhorn Symphony Center in Nashville. This was one of those projects that went smoothly from beginning to end, with everything falling into place and no road blocks in the way. Of the greatest importance to the success of this job was the client’s clear musical goal and realization that a really great organ can’t be all things to all people. We had a well-defined mission: to build an instrument that is a member of the orchestra. To this end we worked from the beginning with Andrew Risinger, organ curator and symphony organist and also organist/associate director of music at West End United Methodist Church in Nashville.
We were appointed, at the very beginning of the project, to the design team that included acoustician Paul Scarbrough of Akustiks in Norwalk, Connecticut and design architects David M. Schwarz, Architectural Services of Washington, D.C. I had worked with both as organ consultant for the Cleveland Orchestra in the renovation of Severance Hall and its E. M. Skinner organ. The design team, under the skillful management of Mercedes Jones, produced a hall that could not be more perfect from our point of view. Seating 1,872, it is beautiful in its traditional design, excellent proportions, and fine materials. It is of the traditional “shoebox” shape that everyone knows is perfect but that few architects are willing to employ. Since, under the direction of Paul Scarbrough, all of the traditional acoustical rules were followed, the result is, indeed, perfect.
Reverberation time is controlled by dampening material that may be added or subtracted at will. There is excellent balance, clarity, and pleasing resonance even in the lowest reverberation setting. With all dampening material lifted out of the way at the press of a button, the hall is ideal for most organ and choral repertoire. In addition, there is one very unusual and practical feature that has an added impact for the organ. The orchestra seating section can be converted to a flat open floor for pops concerts and special events. Most of the transformation is accomplished automatically through a labyrinth of gigantic machinery in the basement. The huge expanse of polished wood flooring adds significant reverberation. This feature also, interestingly enough, increases the usage of the organ. The hall is often rented for weddings. This is perhaps the only symphony hall organ in the world that has a reason to play the Mendelssohn and Wagner marches!
The organ is in an ideal position just above the choral risers at the rear of the stage. The casework was designed in close cooperation with the architectural team and Paul Fetzer whose company, Fetzer Architectural Woodwork of Salt Lake City, built the façade along with the other woodwork of the hall. It affords full tonal egress from the open front chamber behind it, which is shallow for accurate unforced projection. The organ is arrayed on three levels. Most flues are on the first level. Reeds, celestes, some flutes and offsets are on the second, and Pedal on the third, with the exception of the Trombone and Diaphone, which occupy a space extending all three levels. The bass octave of the 32′ Sub Bass is in a most unusual spot—located horizontally underneath the patron’s boxes to the left and right of the stage apron! These large scale pipes produce a soft 32′ tone that is felt as well as heard throughout the entire auditorium. The 32′ Trombone is in its own expression box, and the Swell includes our double-expression system, wherein the softest and most powerful voices are in a separate enclosure at the rear of the Swell with shades speaking into the Swell. The Vox Humana is in its own expression box inside the double expressive division of the Swell and so is, in effect, under triple expression. Accurate climate control has been provided, keeping the organ at constant humidity and temperature. The blower room in the basement has its own cooling system to neutralize the effects of blower heat build-up. Intake air is filtered.
The instrument employs our expansion cell windchests and electric-pneumatic action. This allows uniform, fast and silent action for all pipes no matter their pressure as well as easy console mobility and the borrowing of stops for maximum flexibility. Obviously borrowing is employed heavily in the Pedal, but it is also used on the Great, where the high pressure diapasons 8′ and 4′, string, stopped flute, Cornet and Solo reeds are all available independently. It also makes practical the extension of Pedal stops into the Solo and facilitates an interesting effect, the Tuben stop, which borrows the Swell reeds onto the Solo at unison pitch (Posaune up an octave at 8′ and Clarion down an octave at 8′ along with the 8′ Trumpet).
The console has the usual playing aids, but has been kept as simple and straightforward as possible to facilitate efficient rehearsals. There is a record-playback system—helpful for rehearsals and also for house tours; the playback mechanism can be remotely controlled by tour guides. With the press of a button they can start the blower and select a demonstration piece to be played for public tours, which are a popular attraction in Music City.

Tonal design
The two pillars of tone are diapasons and trumpets. The manual diapason choruses contrast in tonal color and power. The Swell chorus (Manual III) is based on a slotted 8′ Diapason of moderate power with a slightly tapered 4′ Principal and a 2′ Mixture, which is under double expression. The Great (Manual II) has a large scale 8′ Diapason with upperwork through 1⁄3′ Mixture and a slotted, smaller scale double. The Solo (Manual I) has the largest scale and most powerful chorus, all under expression and at 10″ pressure. Its mixture can be drawn with and without a tierce. The trumpets range from closed, tapered shallots on 10″ wind in the Swell to open parallel shallots on 5″ wind in the Great to open parallel shallots on 15″ wind in the Solo, where tromba-type tone is added by the Tubas and Trombone. Built around these pillars is an ensemble of stops with color, definition and sinew that project well to produce power in a manner similar to the orchestral instruments and centered at the orchestra’s pitch. Note that 64% of the stops are at 8′ and 4′ pitch. A most rewarding comment on this subject came after the opening concert in Nashville from the visiting executive director of one of the world’s leading orchestras, who remarked that he didn’t know that it was possible for an organ to be so powerful and at the same time so beautiful.
There are several special tonal features including a newly developed stop—the Diplophone. We wanted to include solo stops of heroic power from each family of tone. Our usual solo Gambas, Symphonic Flute (which employs five different types of pipe construction throughout its compass including double mouth and double harmonic pipes), Tibia Clausa, Corno di Bassetto and Tuba Magna represented the string, open flute, stopped flute, color reed, and chorus reed families, but we needed a solo diapason of equal power. We tested normal stentorphone pipes and then double-languid pipes without achieving the character of tone and power we were after. We then tried a double-mouth diapason. Mouths on either side of the pipe allow a greater mouth width than is possible with a single opening. This, combined with high pressure, produces tremendous power with smoothness and beauty. Finally, we included a powerful mounted Cornet (unusual for us) because it is a tone color completely outside the range of the orchestra and should offer interesting possibilities to contemporary composers.
For a stop that can fade away to nothing, we added our Cor Seraphique and Vox Angelique. These are very strongly tapered stops of the muted (or hybrid) variety. They are neither strings nor flutes and have a mysterious quality that is very attractive, with a harmonic structure that promotes projection when the Swell boxes are open, but is soft enough to disappear with both boxes closed. This stop is extended to 16′ to provide the same effect in the Pedal.
The Pedal includes all classes of tone at 16′ pitch: open wood, open metal, string, hybrid, stopped wood, and two different weights of chorus reed tone, both under expression. One of the most important 16′ voices is the Violone, which gives a prompt clear 16′ line to double and amplify the basses of the orchestra. The most unusual, and in some ways most important, stop of the organ is the 32′ Diaphone. Diaphones have a tone quality that ranges from a very dark, almost pure fundamental to a slightly reedy quality. Since this organ is equipped with a 32′ Trombone under expression, the Diaphone is voiced for pure fundamental tone of magnificent power. It produces more solid fundamental bass than a large open wood diapason and it speaks and releases promptly.
Our Pizzicato Bass stop, which gives a clean pointed bass line when added to other stops playing legato, is included because of its value in choral accompaniment. There is a special Sforzando coupler that is engaged only when the Sforzando lever, located above the swell shoes, is touched. It allows Solo stops to be momentarily added to the Great for accent. The Solo has a variable speed tremulant.

Installation and debut
The organ was installed in several phases, which went very smoothly due to the outstanding cooperation and support of the symphony staff, led by president and CEO Alan D. Valentine and general manager Mark F. Blakeman, as well as the excellent building contractors, American Constructors, Inc. The atmosphere was collegial and, yes, there is such a thing as southern hospitality. The casework, display pipes, blowers and large pedal pipes were installed in February–May 2006. We completed the mechanical installation of the organ during the summer of 2006. Tonal finishing was carried out during the summer of 2007. The leisurely and well-spaced schedule avoided the conflicts and last minute scrambles that usually cut tonal finishing time.
The organ was presented to the public at the opening night gala of the 2007–08 season with Leonard Slatkin, conductor, and Andrew Risinger, organist. The program included the Bach Toccata and Fugue in D minor, Duruflé Prelude and Fugue on the Name Alain, Barber Toccata Festiva, and the Saint-Saëns Symphony No. 3. It was recorded for broadcast on SymphonyCast. The exceptionally active Nashville chapter of the AGO has co-sponsored events starting with a lecture-demonstration evening and including the “International Year of the Organ Spectacular” recital featuring Vincent Dubois. The orchestra has presented several programs including a “Meet the Organ” demonstration for students, a “Day of Music” free to the community, a series of noontime recitals, and Thomas Trenney playing accompaniments to the silent films Phantom of the Opera at a Halloween program in 2007 and The Mark of Zorro in 2008. The organ has been used to accompany the symphony chorus in concert and also in several additional orchestra subscription concerts including works by Elgar and Respighi. The 2008–09 season has already presented Andrew Risinger in the Copland Symphony for Organ and Orchestra with new music director Giancarlo Guerrero conducting, the noon recital series continues, and more programs are on the way.
The instrument has been greeted with enthusiasm from the artistic staff of the orchestra and the musicians. The public has embraced it warmly and we look forward to the 2012 AGO convention, where it will be one of the featured instruments.

Berghaus Pipe Organ Builders, Inc., Bellwood, Illinois
La Casa de Cristo Lutheran Church, Scottsdale, Arizona
Opus 224 (2008)

From the organbuilder
Overview
Berghaus opus 224 at La Casa de Cristo Lutheran Church contains 91 ranks, 94 stops, and 5,067 pipes over four manuals and pedal. The instrument takes its place as one of the largest pipe organs in the state of Arizona. The majority of the instrument (Pedal, Great and Positiv) is located on the mezzanine level at the front of the sanctuary, on a concrete platform measuring 42 feet across. The enclosed Swell is located above the musician’s gallery in a resonant chamber measuring 14 by 18 feet, and the Antiphonal is divided and elevated on two sides of the rear gallery, flanking the large rear window.
The casework is constructed from light-golden, rift-cut oak. The design emulates contemporary shapes found elsewhere in the sanctuary. The visually striking façade, including polished tin Principals from the Pedal, Great, and Positiv divisions, takes its inspiration from the McDowell mountain range, located in the northeast corner of the Phoenix valley. A sense of depth is created with the mountain-like arrangement of flamed-copper 16′ Principal pipes from the Great and Pedal divisions. The façade also contains twelve non-speaking wood pipes, painted sage green, in homage to the majestic Saguaro cactus found in the region. Adding to the visual display is the asymmetrical layout of the Trompette en Chamade, constructed with flamed-copper resonators. The twin Antiphonal façades echo the details found in the main organ.

Tonal Approach
We designed an eclectic instrument, taking cues from the American Classic and Romantic traditions, that would be able to handle a comprehensive repertoire, including a wide range of expression, both dynamic and tonal. To that end, there are no less than five manual 8′ principals, ten different 8′ and 4′ flutes, strings and hybrid (tapered) stops of varying tone and construction. The versatility of this instrument results from our ability to treat each of these stops as a beautifully unique voice when used alone, as well as having the ability to blend well, thus creating new and desirable tones when used in combination. This is evident in the Great, which contains the standard French-Romantic foundation of Principal, String, Open Flute, and Stopped Flute.
Given the challenge of creating a large organ with only one expressive division, it was clear from the onset of the project that great care would have to be taken in the tonal finishing process to ensure a seamless crescendo and to create an organ with equally balanced manual divisions. The ranks of the unenclosed Positiv are designed and voiced to provide a remarkable degree of expressiveness, and to serve as a tonal bridge between the Swell and the Great. The overall effect in the crescendo is that of a seamless transition from ppp to fff without experiencing staggering dynamic or color steps.

Tonal Analysis
The Great division consists of 19 stops, 22 ranks, and is mostly divided between two large slider chests, one containing the principal chorus through mixture, the other containing the flute and string stops. The 8′ First Principal is of generous scale, and is constructed of 75% tin throughout. This creates a timbre that is simultaneously bright and full, and gives it a singing quality that provides a strong foundation upon which the subsequent ranks are built. The 16′ Sub Principal is scaled proportionally (smaller) to the First Principal and is extended to be available as an 8′ stop (Second Principal). This gives an alternative diapason tone that is more subdued than its larger neighbor, yet is large enough to be a lighter 8′ texture for the entire plenum. The principal chorus is completed with narrowly scaled mutations, and is crowned by two mixtures: a full 2′ V-rank Fourniture, and a sparkling 1⁄2′ III-rank Cymbale. The Flûte Harmonique is large scale, with harmonic pipes starting at no. 30, and is voiced with a very strong increase in the treble. Other flute stops include a metal 8′ Bourdon, a harmonic 4′ Flûte Octaviante, and a II-rank Gross Kornet, constructed of large-scale open flutes at 51⁄3′ and 31⁄5′ pitches to enhance the 16′ harmonic series. The 8′ Gamba is of slender scale and is gently voiced to be a blending stop. The 16′ and 8′ unit Kontra Posaune is a blending chorus reed of German construction. The 16′ and 8′ Trompette en Chamade contains schiffchen-style shallots, producing a sound reminiscent of older Spanish trumpets, yet it can be used as a crown for full organ. The Great provides a myriad of combinations suited for a range of demands from the liturgical service to the solo organ repertoire.
The Swell division contains 21 stops, 23 ranks, and is “double-stacked,” with the complete principal chorus, mutations, and reeds occupying the lower level. Flutes, strings, and celestes are mounted above. The principal chorus is based on an 8′ Diapason of spotted metal, crowned with a 2′ IV-rank Plein Jeu. The relatively low pitch of this mixture, combined with a narrow scale, allows the pipes to be blown full, which helps to produce a clear principal tone. Furthermore, the mixture is voiced softly enough to give the entire plenum a gentler quality suitable for choral accompaniment. The III-rank Cymbale is designed as a tierce mixture and voiced to its full potential to reinforce harmonics present in the fiery chorus reeds. It also blends well and can be used as a higher-pitched mixture with the principal chorus.
The Viole de Gambe is made of 75% tin and slotted for optimum harmonic development. The combination of this stop with its 61-note Voix Celeste is intended to produce true string tone, and not tone associated with narrow principals or stringy hybrid stops. This approach allows us to keep each of the tonal categories of the instrument separate and distinct. The Swell is also home to the softest rank of the organ, the 8′ Flûte Conique, which when paired with its celeste elicits a most haunting timbre. Other flutes in this division include the 8′ Flûte à Cheminée, which is wood in the bass and is extended to 16′ pitch, and a 2′ Octavin, which goes harmonic at no. 13. This 2′ flute is not intended to be used with the mixture, but rather with the 8′ and or 4′ flutes. However, it works equally well with the principals, as the scale is moderate and the voicing is light. The battery of reeds consists of a full-length 16′ Basson, an 8′ Trompette and 4′ Clairon of French construction, and an 8′ Hautbois featuring coned-in bells and parallel French shallots. When combined with foundation stops, the 8′ Hautbois becomes a most useful solo voice, especially for music from the French symphonic school. The Voix Humaine is of American Romantic construction.
The Positiv division is located adjacent to the Swell, which allows this division, along with the Swell, to accompany the choir. Totaling 19 stops and 19 ranks, the Positiv is based on an 8′ Prinzipal constructed of 75% tin and is complete through a 1′ IV-rank Scharf. The ranks of the plenum are narrower in scale than in the other divisions and provide a good secondary chorus to the Great, especially in Baroque music. The 8′ Gemshorn has a very wide mouth with a low cut-up and a 1/3 taper, giving it a string-like tone. A complete Cornet decomposée including Septième comprises pipes of various construction, from the 8′ Holzgedackt made of poplar to the 22⁄3′ chimneyed Rohrquinte. There are three solo reeds in the Positiv division, including an imitative 16′ English Horn, an 8′ Cromorne, and an 8′ Trumpet with English shallots.
The Antiphonal division comprises 9 stops and 10 ranks, and provides additional support for congregational singing as well as interesting echo effects to the main instrument. Placed on opposing sides of the gallery, the Antiphonal is higher in elevation in comparison to the main organ. The Antiphonal principals are voiced in a mild fashion, to give a sense of surrounding the listener while providing a supplemental role to the main instrument. This approach was preferred to bombarding the listener with sound from the gallery and purposely announcing the Antiphonal’s presence. Of note are the two solo flutes: the 8′ Doppelflöte and the 4′ Flauto Traverso (harmonic), both made of poplar. The organ’s heroic reed, the 8′ Trompette de Fête, is located in the Antiphonal division as well. The Trompette de Fête features hooded resonators and is voiced on 18 inches of wind.
The Pedal division comprises 26 stops and 17 ranks. The division is thoroughly complete to provide ample foundation tone in a variety of timbres and volumes. Fortunately, few of the pedal stops are borrowed, which gives tremendous flexibility to the division as a whole. The principal chorus is based on an open metal 16′ Principal, scaled according to classical principles (relative to the Great 8′ First Principal). The entire chorus provides a solid contrast to the Great and gives excellent support without being woofy. When a more penetrating foundation is desired, the generously scaled 16′ Open Wood is useful for larger combinations. Of particular note is the 31⁄5′ V-rank Pedal Mixture. The first rank of this stop is a tierce (16′ series), constructed of 2/3 tapered pipes. Voiced gently, this rank dramatically enhances the 16′ fundamental tone, while giving the overall plenum a pleasantly reedy tone. This helps to further clarify the Pedal line in contrapuntal textures. As with many of our larger instruments, an 8′ Spitzflöte is included to give a more pointed emphasis to the Pedal line in softer combinations. The reed chorus consists of a 32′ and 16′ Bombarde constructed with pine resonators, and a large-scale 8′ Trompette with English shallots. A 4′ Rohrschalmei is a very characteristic reed useful for cantus firmus solos.

Wind System and Chests
The vast majority of flue stops in this organ are placed on slider and pallet chests, which we believe speak to the heart (and origins) of good organ building. Principals and flutes in each division (sans Antiphonal), are placed on separate chests. This helps to solidify each respective chorus. We have insured absolutely steady wind by incorporating a large number of bellows and schwimmers. By contrast, reeds are placed on electro-pneumatic chests, allowing wind pressures to vary to suit the tonality of each reed. Furthermore, wood wind conductors are used throughout the organ, which helps to eliminate turbulence and the resulting wind noise. Pneumatic pedal and offset chests are supplied with their own regulators and concussion bellows.

Console
Design elements of the four-manual console were taken from architectural themes found in the church. The contemporary English-style drawknob console is low profile, and contains state of the art controls for the combination action and record/playback systems. Controls were placed inside a drawer to the organist’s right in order that the console be visually free of electronic clutter. The shell is made of light-golden, rift-cut oak to match casework. Drawknob jambs are made of burled walnut. Keyboard coverings are bone and feature top-resistant tracker touch.

Construction Timeline
The creative journey to construct opus 224 began late fall 2007, with final voicing completed spring 2009. The organ was dedicated in a festival service organized by Dr. Jennaya Robison, director of music, and played by Dr. Homer Ashton Ferguson III. Dr. Weston Noble conducted the combined choirs. The organ was also featured at the 2009 Region IX AGO convention.

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.

Russell & Co. Organ Builders,
Chester, Vermont
First Presbyterian Church, Ithaca, New York

From the builder
The term magnum opus is often used in the organbuilding trade to denote the apotheosis of an organbuilder’s career. It is an impressive expression, and the organs that receive such an accolade are usually equally impressive. It is interesting to note, however, that the distinction of magnum opus can be an ephemeral one. What a builder thinks of as his ‘biggest and best’ may be eclipsed just a few years later with an opus magnum novum. In any event, at the outset of a project an organbuilder has termed his magnum opus, he inevitably approaches the creation of the instrument with great reverence and dedication. When we received the contract to build our opus 47 for First Presbyterian Church in Ithaca, New York, we knew this would be our magnum opus and, regardless of whether a grander organ would leave our shop in years to come, took on the project in this way, making no little plans to design and build a pipe organ worthy of this special moniker.
First Presbyterian is a grand Romanesque stone structure built in 1894 and located in the heart of downtown Ithaca. The sanctuary seats 500 under a high barrel vault, coffered and richly ornamented with plaster florets. The church enjoys a large, vibrant congregation and an equally active music program, including a sizable adult choir, children’s choir, and handbell choir. In conjunction with the organ project, the sanctuary was renovated to remedy the less-than-desirable acoustics. Previously, the entire floor of the room was carpeted, and the pews were cushioned in heavy velvet. A completely new ceramic tile floor, new and less-absorbent seat cushions, hardened wall surfaces, and a new rear wall designed to reflect sound randomly all contribute to a lively and supportive acoustic, approaching three seconds of reverberation.
The preceding instrument began its life in 1901 as Austin’s opus 39—a three-manual instrument of 47 ranks, including a five-rank Echo organ added in 1930. The organ was installed in the front of the church behind a handsome white oak case crowned with a magnificent central tower rising nearly the full height of the sanctuary. Designed in traditional early 20th-century style, the organ contained the typical myriad of foundation stops, with sparse trimmings of upperwork, undergirded by an ample and satisfying pedal department. Sixty-five years later, Austin was called to rebuild the organ in keeping with the tonal thinking of the day. The result was completely new pipework typical of late 1960s construction and voicing; the Echo organ, thanks to the organist, Dorothy Arnold, was retained and unchanged. With many manual stops sharing common basses, and the pedal division largely borrowed from the manuals, there was little foundation tone. The scaling of the new pipework exacerbated this condition, with halving ratios that resulted in a thin bass and a treble ascendancy unwelcome in so dry a room. The impressive 16¢ and 8¢ 1901 façade was completely replaced by much narrower-scaled pipes with English bay mouths, leaving large, odd-looking gaps between the pipes.
By the 1990s, the organ proved to be inadequate for the many demands the church’s music program placed upon it. Mounting mechanical problems toward the end of the decade that rendered the instrument increasingly unreliable led the church’s organist, George Damp, and the director of music, Larry Doebler, to realize that a completely new instrument was needed to correct the tonal inadequacies of the existing instrument and to fill the needs of the extensive music program. The church named John Schwandt as consultant on the project. Dr. Schwandt recommended requesting proposals from lesser-known builders of high quality. After a national search, Russell & Co. of Chester, Vermont was selected in late 2002 to build the new organ.
A profusion of new romantic organs in recent years, as well as a renewed reverence and interest in the work of early 20th-century American builders, specifically Skinner, was the milieu for the design and construction of this instrument. While Russell & Co. have built several large instruments along French romantic lines, an American romantic/ symphonic organ presented a new challenge: how to take all the lessons learned from our previous instruments, combine them with a century of progress in American organbuilding, and produce an organ capable of accompanying congregational song, playing choral and orchestral literature, and still be able to play the solo organ repertoire, all the while staying true to a ‘symphonic’ ideal.
This challenge was met valiantly with an effective partnership between our firm and George Damp. Having spent all his professional life as an organist, teacher, and church musician, George brought years of experience and a clear idea of what he wanted to the drawing board—a grand, large-scale organ that would make Ernest Skinner proud, but would also not disappoint the likes of G. Donald Harrison. While orchestral voices and ensembles were of great importance, so too was the presence of well-developed and blended choruses in each division.
Our initial proposal was for a three-manual organ with a separately enclosed Solo and Choir sharing one manual. However, during our early discussions with the church music staff, it became clear that to fill all the demands placed upon it, a significantly larger, four-manual instrument would be better suited and would eliminate several reluctant compromises in the original design. Having completed the rebuild of a four-manual Æolian-Skinner, opus 1433, for First Unitarian Church in Worcester, Massachusetts, and the building of a new, large three-manual French romantic organ for the Cathedral of St. Paul, also in Worcester, we felt ready to tackle our first new four-manual organ. During the selection process, George visited Worcester’s First Baptist Church, home to a rebuilt Reuter for which we constructed a new, large four-manual Skinner-style console. Skinner consoles have long been renowned for their visual elegance, impeccable craftsmanship, and intuitive and comfortable ergonomics. It was agreed First Presbyterian should possess such a console to complement the new organ.
First Presbyterian has long been host to performances of choral and chamber music by numerous local ensembles, and the acoustical renovation that preceded the organ installation only made the space more attractive for outside groups’ use. Knowing this, we included in the initial proposal a small division designed for use as a continuo organ at chancel level. George was hesitant at first—it seemed like a water and oil situation to have such a division included in a grand romantic organ. However, with a large, higher-pressure instrument as the main organ, George and Larry Doebler agreed that it would be futile to attempt to use it in continuo playing, and not only agreed to the division’s inclusion, but encouraged its enlargement. What started out as a small five-stop division grew into a full-fledged low-pressure Positiv, complete with a Sesquialtera and a very gently voiced four-rank Scharff. Its elegant case makes use of the crown and columns of the large throne chair that used to sit in the middle of the chancel, blending the case with the rest of the chancel decoration.
While spacious, the two front organ chambers had previously housed 47 ranks of pipes, including a very small pedal division. One of the project’s greatest challenges was to make 79 ranks of pipes fit in these same chambers—including a large-scale independent pedal division with three 32' stops—while maintaining easy access to each pipe and mechanism. After much experimenting in the forgiving world of computer-aided design, a layout that achieved both of these goals was reached. Aside from the Antiphonal and Positiv, the entire instrument is installed behind the organ case, with the Great, Solo and Choir divisions to the congregation’s left, and the Swell and Pedal on the right. There is no ceiling over these chambers, allowing for a great deal of sound to ascend into the barrel vault over the chancel, creating a wonderful blending chamber of sorts, which then projects the sound well into the room. Even from the center of the chancel, it is difficult to tell from which side sounds are coming.
The Antiphonal organ is located high up in the right rear corner of the sanctuary. The Antiphonal Swell division, consisting of the original Echo organ with two additions, is housed in the former Echo organ chamber. The two stops of the Antiphonal Great sit on a newly constructed ledge in front of the chamber, with the pipes from the 8' Prestant forming a simple and elegant façade.
The console constructed for opus 47 models the console at First Baptist in Worcester. Built of quarter-sawn red oak and walnut with a hand-rubbed oil and stain finish, it complements the elegance of the renovated sanctuary and restored organ case. With manual keys of 10th-cut ivory and ebony, and pedals of maple and ebony, the console immediately has a luxurious tactile feel. Through many consultations with George as well as with the organists working in our own shop, the selection and layout of controls were designed to be as intuitive to the player as possible. The stopjamb layout takes its cue from the tall consoles of English cathedrals; this provides the vertical space to lay out the complete choruses of each division in one line, making drawing every plenum quick and straightforward. Though a complete list of playing aids and mechanicals accompanies the specification, several are worth noting here. With the choral accompanist in mind, the Swell is provided with ten divisional pistons, and pedal-to-manual combination couplers with discrete memories are available on each division. A 99-level combination action is included with 16 general pistons and a sequencer; additionally, each piston can be easily modified as to which stops it affects, releasing the player from the distinction and restraints of divisional and general pistons. Divisional cancels are also provided by pushing the division nameplate on the stopjamb.
The key and stop action throughout the instrument is electro-pneumatic, a departure from our usual practice of employing slider and pallet chests. The chests are modeled on late 1960s Aeolian-Skinner pitman chests, with several of our own modifications. Even the Positiv, speaking on 23⁄4" pressure, plays on a pitman chest and works beautifully, resulting in quick and desirable pipe speech, ideal for its anticipated continuo use.
A design goal from the outset of the project was to make the organ large enough to have four complete manual divisions (seven, including the Positiv and Antiphonal Great and Swell), but to keep costs manageable, all the while not sacrificing quality. To this end, we looked to the existing Austin pipework, all having been new (with the exception of the Echo) in 1969, to see what might be reused in the new organ. While hard to believe this neo-baroque pipework could blend its way into an American romantic organ, we found much of the pipework was well constructed and cut up low enough to permit its successful rescaling and revoicing in a very different style.
Of the 40 completely new ranks of pipes added to the organ, all new choruses and flutes are constructed of 94% lead alloy, a practice we have long employed, allowing our voicers to achieve a degree of tonal superiority unattainable with the use of lighter, higher tin content alloys. In general, this allows the 8¢ line to be weighty and warm, progressing through a velvety chorus to light and silvery upperwork—all mixtures in the organ are also of the same high-lead content. The epitome of this construction and voicing style is the 8¢ Montre on the Great, a 42-scale Diapason more English than French, despite its name. Being placed outside the Great expression box, the Montre’s tone is commanding, warm and strong, and is paired with the enclosed 44-scale 8' Principal for lighter choruses. True to the design objective, choruses through at least 4¢ were provided in the three main manual divisions (Great, Swell, Choir), resulting in three very independent divisions that terrace and blend successfully for the performance of French literature. With the old Great 8' Principal revoiced as the Swell Diapason, and the 45-scale English Diapason in the Choir of special variable scale, the five combined 8' Diapasons create a rich, singing tone that serves as a lush solo color, as well as the basis for the aforementioned well-blended choruses.
One of the hallmarks of an American symphonic organ is the abundance of orchestral reeds, so carefully developed by the likes of Skinner a century ago. Fittingly, opus 47 has a delicious array of imitative stops spread out amid the manual divisions. The demand for these stops allowed us to use several ranks we had been storing in our stockroom for many years while the popular organ style called for very different reed stops. In the Choir division, the Clarinet finds its traditional home, and comes to Ithaca as a restored Johnson Bell Clarinet. In our study of early 20th-century American organs, a common finding was that the Choir division, while potentially having enough foundation tone, nearly always lacked the trumpet-class reed timbre to assert itself against the Swell organ. In this light, the second Choir reed deserves special note as an unusual stop, even in this age of rediscovered orchestral sounds. The 8' Waldhorn uses restored Aeolian pipes from the Higgins estate in Worcester, Massachusetts. This medium-scaled, capped trumpet is not quite a French Horn, and not quite a Trumpet, but something in between. It has a chameleon-like quality in that it is a beautiful and haunting solo voice, but when drawn with the full Choir, it acts as a chorus reed, giving the Choir a definite presence amidst full organ.
Two new reeds, the English Horn in the Solo, and the Orchestral Oboe in the Antiphonal Swell, were beautifully voiced by Chris Broome, turning out exactly as we had wanted them, and possessing striking imitative qualities.
For climactic moments in both repertoire and accompaniments, two solo chorus reeds are provided in the Solo division. The enclosed Tuba Mirabilis has harmonic resonators from tenor F# and is voiced on 15" pressure, providing the traditional dark, smooth and powerful tone suggested by its name. The 8' Silver Trumpet, played on 10" pressure, serves to contrast with the Tuba for a different effect. Envisioned in the same manner as the Solo Trumpet Harmonique at Yale’s Woolsey Hall, the pipes are constructed with French shallots and placed outside the Solo enclosure, yielding a brighter and brassier tone. While neither stop is oppressively loud, when combined they yield a tone of refined power that can top full organ with single notes.
Another criterion from early on in the project was to have a profusion of string stops of varying power and brightness to enable a truly orchestral string crescendo from pp to ff. While there are the usual strings sprinkled throughout the Choir and Swell, the Solo strings truly cap the string chorus, possessing incredible intensity and brilliance. Although the Solo was originally designed with one pair, the discovery of two ranks of Skinner orchestral strings in our stockroom led to the addition of a second set to be the pinnacle of the string chorus. Voicer Ted Gilbert worked wonders with these two pairs—the Gamba is the quieter of the two, possessing an almost woody quality, whereas the Cello represents the extreme limit of bright, powerful, shimmering string voicing. Twelve ranks of string or undulating tone in the organ, from the Swell Flauto Dolce through the Solo Cello, provide a seamless powerful crescendo, made even more effective with the use of double expression in the Solo.
No symphonic organ is complete without an expression system that can fully restrain the power of the instrument and instantly change the dynamic of the stops drawn. To this end, no fewer than six Skinner-replica whiffletree expression motors are used in this organ. While the Swell, Choir, and Antiphonal Swell are enclosed and expressive as expected, the Solo and Great warrant description of their expressive capabilities. From the outset, we had designed the Great to be partially enclosed, mainly the reeds and upperwork. Additionally, the Solo was to speak through its own shades into the Great box, providing the division with the aforementioned double expression.
The Great organ’s expressive capabilities were expanded early on with the decision to enclose the entire division with the exception of the 8' Montre and 16' Principal. Through careful scaling and voicing, the division doesn’t suffer its enclosure with the shades open, and contains the tonal resources necessary to lead enthusiastic congregational singing with all 500 seats filled, as well as serving its traditional role in the performance of organ literature. However, with the added benefit of 16-stage expression, these same tonal resources can be manipulated to match any congregation size, as well as provide another enclosed division of power for choral accompaniment.
At the same time, to give the Solo and Great more independence from each other, we added a second set of shades to the Solo, allowing the division to speak directly into the chancel. This provides the Solo division with a third expressive option. As installed, the Solo swell box is behind the Great box and four feet higher. The primary Solo shades open into the Great, with the Solo chancel shades being at the very top of the Solo box, four feet high, and opening directly into the room. While giving an acceptable dynamic range, these smaller shades provide an enormous timbral range, noticed especially with the strings. With the full Solo string chorus playing and the main Solo shades open, the full weight of the 8' stops comes through—one can almost hear bows drawn across the strings. However, when the upper shades open, the full range of upper harmonics from these stops erupts from the box, filling out the sound just when you thought it couldn’t be any brighter and more sonorous.
The control of all these expression options is met with four swell shoes, including the crescendo shoe. The Solo shoe normally controls the chancel shades. However, when the “Solo Double Expression” drawknob is drawn, the Solo shoe operates both sets of Solo shades, as well as the Great shades, in a set sequence to give the maximum crescendo possible. Additionally, a second drawknob closes the Solo chancel shades should that be desired, and sets the Solo shoe to control only the main Solo shades. The Great and Antiphonal Swell expression functions are independently assignable to any shoe, including crescendo. When not assigned, the shades default to a position settable by the organist. Harris Precision Products retrofitted two of their standard drawknob units with potentiometers to set these defaults, and thus these controls are seamlessly integrated into the console via rotating drawknobs. All Swells to Swell is provided to afford simple control over the entire dynamic range of the organ, and indicators are provided below the coupler rail to show the position of each set of shades.
The use of such sophisticated expression functions allows the organist to present the full dynamic range of the orchestra, and the use of the smaller Solo chancel shades allows for the ultimate in dynamic and timbral expression, a feature unique to this organ, and one we hope to further develop and use in subsequent installations.
To complement the varied and colorful manual divisions, a large, independent Pedal division affords the appropriate bass sonority for whatever registration is drawn on the manuals. Consisting of eleven independent ranks and 29 stops, the Pedal organ is augmented by judicious borrowing from the manuals. Four 32' stops are provided to underpin the instrument and provide a true feeling of gravitas. From the initial planning phases of the project, it was made clear that no digital voices were to be used in the organ; thus, all 32' stops play real pipes, or are derived. The Bourdon, of generous scale, is voiced gently for use with the softest registrations, but with enough quint in its tone to be made stronger as more pedal stops are added. The 32' Principal, an extension of the 16¢, uses Haskell pipes to GGGG#, the rest of the 32' octave being a resultant. The full-length 32' Contra Posaune, also masterfully voiced by Chris Broome, gives plenty of weight and power to full organ, but without being brash or rattling. For a ‘second’ 32' reed, the Harmonics is a 102⁄3' cornet, derived from the Great 16' Double Trumpet and 16' Gemshorn, giving the semblance of 32' reed tone underneath smaller tutti registrations.
With the added features of sophisticated expression, as well as the inclusion of more fully developed choruses, First Presbyterian’s instrument represents a logical and successful extension and merging of the two dominant styles of 20th-century American organbuilding: the symphonic and American classic schools. The instrument serves as a platform for the successful performance of a wide body of organ literature, as well as fulfilling its accompanimental roles. In its design, construction, voicing and tonal finishing, we feel truly proud to call this instrument our magnum opus, regardless of what instruments leave our shop in years to come, and thank First Presbyterian for the opportunity to set our sights high and build an organ we have so long dreamed of creating. We therefore commend this instrument to the glory of God and the people of First Presbyterian Church as a product of our finest craftsmanship. May it long bring joy and inspiration to those who hear and play it, just as it has inspired us as organbuilders in its creation.
Those working on the project included: Stephen Russell, David Gordon, Gail Grandmont, Carole Russell, Theodore Gilbert, Jonathan Ortloff, Larry Chace, Frank Thompson, Matthew Russell, Peter Walker, Allan Taylor, Eric Johansson, and Andrew Lawrence.

From the organist
Now in my fifth decade of deep affection for the pipe organ, its music, and its role in worship, I am brought to this point of extraordinary magnificence in the creation of the opus 47 Russell & Co. organ. During these five decades, I have witnessed many trends and fads in organbuilding. The commitment of this church to the pipe organ as its primary medium for the leading of congregational song is all the more inspiring to me.
This instrument transcends the fads of recent decades. The organ/sanctuary committee, formed by this church in the fall of 2000 and guided by our organ consultant, John Schwandt, selected several organbuilders to consider for the project. This committee authorized my colleague Larry Doebler and me to travel far and wide to experience the work of the builders we had selected as finalists, each of whom subsequently visited the church to inspect the sanctuary space and existing organ. In the end, we all had no doubt that Russell & Co. was the appropriate choice for us.
While we were confident that our new organ would be very fine indeed, we could not have anticipated the level of magnificence that has been achieved here by Stephen Russell and his colleagues. In my 50 years of playing pipe organs, I have never been privileged to play an organ so elegant, expressive and versatile as this one. The word synergy is one that I have never before been comfortable using. This powerful word, meaning “combined or cooperative action or force,” is the perfect term to describe the wondrous emergence and continuing presence of this organ. Beginning with the collective sharing of the original committee, the guidance of Anita Cummings, pastor of this church at the outset of the project, the beneficence of Mrs. Dorothy Park, church member and donor of funds for this organ, the courage and vision of church members to undertake and fund the acoustical transformation of the sanctuary from sonically “dead” to vibrant and moderately reverberant, and the mutual respect and creative sharing of organbuilder, consultant and resident organist, have resulted in the ultimate synergy: the harmonious blending of thought, craft, sound and space that is far greater than the sum of its parts.
I offer gratitude and the highest of commendations to master organbuilder/voicer, Stephen Russell, his dedicated staff, and the many others who have had a hand in the three-year process of the emergence of opus 47!
—George Edward Damp

From the church
The history of our new Russell organ begins with the construction of our current sanctuary in 1894. In 1901, the Austin Company installed our first permanent organ (the oak façade that currently supports the visible organ pipes behind the choir is part of that original installation). In 1930, the Echo organ (above the southwest entrance to the sanctuary) was added. In 1969, Austin built a completely new organ in the chancel, one typical of that period—an instrument that, with its sheer power and rough voicing, overwhelmed our beautiful, but acoustically rather dead, sanctuary.
Problems with the Austin organ started to appear in the early 1990s. Minor problems continued to occur, and it was clear that something needed to be done. An organ/sanctuary committee was formed that, early in its existence, possessed the keen insight that the sanctuary itself was a part of the organ (the box that the organ’s voice is dispersed into), and that any renovations to the organ must be accomplished within the acoustical framework of the sanctuary.
As a result, the committee hired an organ consultant, John Schwandt, and an acoustical consultant, Scott Riedel, to guide them through the decision-making process of repairing our organ. Each made an initial, individual presentation to the committee, but most memorable was their joint participation in a lengthy “town meeting” with the committee and members of the congregation. The meeting ended with a focus for the project—to improve our worship experience by enhancing both music and the spoken word through renovations to both the organ and the sanctuary.
Early on in this process, then-pastor Anita Cummings and organist George Damp approached Mrs. Dorothy Park with the invitation to become a supporter of this exciting adventure for the church. After several subsequent discussions, Mrs. Park indicated that the church deserved the finest organ created by the finest builder, and that she would cover the cost of the organ if the congregation would pay for the acoustical renovations.
A clear consensus decided that Stephen Russell was the right person to build the new organ. At the same time, Schickel Architecture of Ithaca was selected to design the renovations to the sanctuary. Several significant changes to the sanctuary were implemented to improve the acoustical environment. Certainly the most outstanding component of the sanctuary renovations is the reconstruction of the rear wall of the sanctuary. Its subtle sunburst pattern surrounding a high circular window is both extremely pleasing to the eye as well as functional in randomly scattering sound.
Suffice it to say, every aspect of the organ, from its general layout to the voicing of each individual pipe (all 5,000 of them) was accomplished with the unique features of our sanctuary in mind. The outcome is truly a gift for the ages, something that First Presbyterian Church can share with Ithaca and the surrounding area for decades to come. One can only hope that the generosity of Mrs. Park and the efforts of those involved in this project will be more than repaid by the joy and exhilaration shared by all those who experience our wonderful new organ.

From the consultant
It is a privilege to offer a few words regarding Russell & Co. opus 47. In a world that so desperately hungers for and needs beauty, it is satisfying to have been a part of a long process that has ultimately yielded a thing of great beauty that will inspire the generations yet to come.
My primary involvement in this project occurred before contract-signing. It is my fervent belief that consultants should provide general education and thereby enable church committees to make an informed decision about what is best for their congregation’s worship and community life. However, before we could start to talk about organs, it was very important to have the bigger picture in perspective, namely the inferior acoustical properties of the room. The committee wisely considered the importance of good acoustics that benefit congregational prayer, singing, oratory, as well as but not limited to instrumental music. Scott Riedel provided acoustical consultation; the action taken on most of his recommendations yielded a vastly improved sacred space.
The pipe organ, while not the only possible instrument for worship, remains the best single instrument to lead corporate worship because of its ability to sustain tones from soft to loud and from every pitch level. A well-designed and constructed pipe organ should enable an organist to creatively and expressively accomplish this musical leadership, often interpreting music of many different styles. It was my recommendation that an organ of rich, warm tone and with ample variety of color from all pipe families (principal, flute, string, and reed) be considered. The great organbuilders of the past were not striving to build instruments after someone else’s style, but to create organs suited to the rooms in which they were installed and reflecting the cultural identity of their time and place. That Russell opus 47 resembles in some aspects organs of the early half of the 20th century is entirely irrelevant. The fact remains that it is not an E. M. Skinner organ, an Æolian-Skinner organ, a Kimball organ, or any other organ. Rather, I believe that this instrument transcends labeling of any kind. Opus 47 has richness of color, overall warmth, and clarity. In previous periods of organ building, rich fundamental tone and clarity were thought to be mutually exclusive attributes; one could not have both. The refined voicing and the mechanical perfection of the pitman windchest exemplify an organ that will allow for music of any style. Congratulations are due to the committee and congregation for investing in their future so well!

The First Presbyterian Church
in the City of New York,
New York, New York
The First Presbyterian Church took root as a dissenting group of Scots and Irish Protestants who worshipped in a private home in 1706 and organized a congregation a decade later. By 1719, their first church building opened for worship, leading to a long and continuing history of controversial views regarding man’s relationship to religion, scripture, science, and politics. “The Church of the Patriots” survived revolution, fire, and urban expansion, dedicating the present church in 1849.
Among those on Old First’s roster of notable preachers was Harry Emerson Fosdick, who in 1922 declared from the pulpit that The New Knowledge, as postulated by Charles Darwin, was not inconsistent with Christianity. The uproar spread like wildfire; even the Presbytery of Philadelphia met in the home of John Wanamaker to discuss the matter. An unrelenting three-year campaign by notorious fundamentalist William Jennings Bryan led Fosdick to resign (without changing his views). Fosdick, a longstanding friend of the Rockefeller family, subsequently served as pastor of The Riverside Church for nearly half a century.
Only months before the demolition of the World Trade Center, Dr. Jon M. Walton became the Senior Pastor of First Presbyterian Church. He would soon inherit a stunned city and a congregation numbed by the murder of their members and the orphans left behind. Beginning their fourth century, the congregation and their pastor continue to rebuild—spiritually, physically, and emotionally. Out of tragedy, the church has strengthened, grown steadily in membership, and commissioned pipe organs for both the chapel and the sanctuary.

The Guilmant Organ School
During French composer and organist Alexandre Guilmant’s 1898 American tour, he and Dr. William C. Carl, organist and choirmaster of First Church, decided to open the United States’ first school for organ and church music, with instruction based upon the master’s method of teaching. The Guilmant Organ School’s first class was held on October 9, 1899 and offered instruction to church musicians until the early 1970s. The Guilmant Organ Recital Series continues in modern times, as part of the church’s rich music program that includes oratorio performances by the church’s respected choir and orchestra.

Previous instruments
Initially, conservative worship at First Presbyterian did not permit musical instruments or concert literature; unaccompanied psalmody was provided by a vocal quartet. They were permitted to sing the works of Palestrina, Victoria and Orlando di Lasso in the chapel, but only as entertainments and never at worship services.
In 1888 Roosevelt’s III/52 Opus 368 was built for the east tower gallery. When the elaborately carved chancel was added in 1920, the organ was replaced by Skinner Organ Company’s Opus 293, a IV/72 in the north chancel chamber. Its Echo division was given residence in the bell tower, speaking through an impossibly small grille in the ceiling. The doomed division was installed in a giant meat refrigerator with shutters, Skinner’s attempt to defeat the elements.
By the 1960s, the heating system had “baked the Skinner to death,” according to the late Dr. Robert S. Baker (1916–2005), then organist and choirmaster of the church. Tonal tastes had changed, and Austin Organs, Inc. installed their IV/85 Opus 2048, dedicated in 1965. The planned revamped Echo division never came to be, but the meat locker remains.
Upon Dr. Baker’s retirement in 1988, he was succeeded by his student, William F. Entriken. During Dr. Entriken’s ongoing tenure the church commissioned two pipe organs, both of which were designed and built by Sebastian M. Glück. In 2004, the Rees Jones Memorial Organ, a Georgian-inspired instrument tuned in Werckmeister III, was installed in Alexander Chapel. A recording of Opus 8 is available from the Organ Historical Society. The large sanctuary organ, Opus 12, was completed this year, funded by both First Church and the generosity of donors who gave individual stops or entire choruses of pipework in memory or honor of special people in their lives.
—Benito Orso

From the tonal director
There are advantages to not being “the first man at bat” when it comes to designing a pipe organ for a particular room. One benefits from the lessons of the past: what did or did not work tonally, what physical or environmental conditions helped or hindered the making of music, and what resources musicians may have used most often or what they felt was wanting.
Prevailing scaling and voicing practices of the 1960s (small scales, even smaller scales for the reeds, underlength resonators, low cut-ups, minimal languid treatment), coupled with an acoustic that “eats bass” and a chambered installation, conspired to keep the organ’s sound from reaching the listener.
Another characteristic of organs of the era (even very large ones) was the frustrating disposition of stops, often found at the wrong pitches in the wrong divisions for the accurate registration of the established literature. With enough stops drawn, the liturgy, hymnody, and anthem work were adequately accompanied, but registrational authenticity, saturated color, energetic drive, and cohesive clarity remained elusive.

The new approach
Two main divisions share the second manual: the superordinate Werck, inspired (in concept) by the late 16th-century Hamburg school, and the Great, a more familiar-looking Anglo-French amalgam with both 18th and 19th century ingredients.
The previous organ had no Great reeds, a Harrisonian trend that inevitably created balance problems. The provision of the Great Cornet, Trumpet, and Clarion in the new organ enables the rest of the organ’s reeds to fulfill their duties without compromise, and makes the 18th-century repertoire of several cultures come alive.
Both of these divisions can move about the organ via the coupling system, and if the Werck is used as the main division in early Northern literature, the Great can serve as the Oberwerk, the natural foil, distinguished by character more than brute strength.
This permits the Choir division to serve as its namesake, a secondary Swell rather than a penumbral “toy Positiv” of compromised and disjointed identity. Far less bold yet more colorful than the Solo department, the Choir still retains the essential classical elements within its accompanimental palette and cluster of instrumental pastels. A coherent collection of stops duplexed from the Great is available on this manual as well.
Large American Swell divisions have taken on a somewhat inelastic grundriss, the legacy of multicompetent sovereignty bestowed upon them by the English and thriving here through the Skinner school. And so it should be, a sensate plenipotentiary, home to a chorus of diapasons, a choir of flutes, two sets of undulants, the ubiquitous oboe and regal, and a molten battery of harmonic trumpets. Large scales and shallots with parallel walls (brilliance) and flat bottoms (fundamental) conspire to create a controllable, caged beast. My stratagem was not to reinvent the wheel, but rather to strip the execution of the formula of all shyness and vagaries.
Because we retained the cantilevered windchests from the previous organ (what was so bizarrely called “functional display” half a century ago), it was necessary to execute some compensatory tonal maneuvers for the enclosed divisions. Chambered organs of the period added to the disadvantage by drastically underscaling the expressive sections already in a sequestered relationship to the Great.
The Solo division is home to the usual suspects for an organ of this size and style. The soviet of harmonic bombardes is more brilliant yet less richly dense than the Swell battery. The three orchestral reeds, like all the color reeds in the organ, are made of common metal, rather than spotted. The French Horn and flat-top English Horn are legacy ranks from the Skinner, but alas, were so drastically altered in the 1960s (lowered pressures, revised resonating lengths, new tongues, new wedges) that they are merely historic metal, and we cannot claim lineage. Like the Choir Flügel Horn, they were rebuilt for this installation and are successful and convincing.
The Grand Chorus VIII is “the third Great,” the only mixture in the organ to embrace the 16′ harmonic series, voiced on 8″ wind and mounted in a commanding position in front of the Solo enclosure. It is made of spotted metal, although the 16′ rank is almost pure lead and the tenebrous 51⁄3′ contraquint is subdued. This lends gravitas and avoids murkiness.
The Pedal department takes advantage of the instrument’s electro-pneumatic action, supplementing its own structure with stops from the manual divisions. Some excoriate this centuries-old practice, but obdurate modern practitioners and their clients welcome the opportunity to mix mezzo-forte hues for the sake of nuance.
The full-length 32′ Helicon is not overly noisy, but rather a gentle tympani roll beneath the ensemble. The Harmonics of 32′ changes composition as it ascends the scale, maintaining clarity and immediacy of pitch identification in its reedy rumble. The recombinant effect of the two stops makes itself known without the vulgarity of a “loud for the sake of loud” voice that can be more ruinous than dramatic.
America’s half-century love affair with horizontal blatancy seems to have reached its dénouement as musicians and builders realize that a more solid and focused formant may be a wiser choice for a herald stop. The key to success is to avoid the objectionable ends of the bell curve (splatter and honk), and work toward a brilliant, focused, pure tone, devoid of grittiness and fringe harmonics. Here the Tuba projects a definite “aw” vowel, not a nasal, short “a.” After the stop’s inauguration, I returned to revoice it on 12″ rather than the original 10″ pressure. The result is that it speaks with greater authority and majesty, with no loss of focus or nobility.
Are 93 ranks sufficient? Certainly, although in context I do not believe that there is any wasted metal in the organ. Nonetheless, part of First Presbyterian’s liturgical and musical tradition involves the choir singing from the narthex and the east tower gallery as well as the chancel. This is a church that fills its pews with energetic singers. The vision of a Tower division, within the church, encased where the Roosevelt once stood, is the reason for preparing for it in the console. Keeping it within the church itself, at the same level as the main organ, away from bells, frost, and pigeons, should assure a happier fate than “echoes of the past.”
Both the new north balcony façade with its Zimbelstern and the console were designed to match the existing architecture of the room. The console cabinetry is oak, carved to match the window tracery found in the building. The interior is walnut, as are the manual accidentals and Skinner-style key cheeks. Pedal accidentals are rosewood, and the drawknobs are pao ferro. The three medallions that grace the music rack are jade.
The extensive combination action is a modern expectation, especially for a church with such a highly developed music program. We advise our clients that the combination action is likely the first item to need technical attention in a pipe organ, and we do keep more “precious” gadgetry to a minimum. Less-seen features are a separate set of pistons for the couplers, the Pedal on Choir coupler, and varying species of wood used for the toe studs, allocated by category. The divisional tags above each drawknob field, when pushed, cancel the knobs of their respective divisions.
The two organbuilders most responsible for the technical and structural realization of this installation were Robert Rast and Albert Jensen-Moulton, general manager of the firm. During onsite voicing and tonal finishing I was assisted by Mr. Jensen-Moulton at the console, whose ears and judgment I trust to achieve the firm’s tonal signature.
I firmly believe that it is the small organ that challenges the creativity and ingenuity of both the builder and the musician. But an instrument of broad scope does not relieve the designer of the obligation to apply all that history has taught us, especially regarding the literature. The “concert” literature was written by church organists for the instruments they played for worship. The scores are the recipe books, and the surviving instruments the resulting cuisine. The large, eclectic organ is not a cultural grab-bag of incompatible material, but a conceptual coalition that must result in stylistic unity, bearing the sound and personality of the builder.

Jack M. Bethards is President and Tonal Director, Schoenstein & Co. Organ Builders. A San Francisco Bay Area native, he holds Bachelor's and Master's degrees from the University of California at Berkeley. He has been a professional musician and is currently active in the American Guild of Organists. He is past president of the Associated Pipe Organ Builders of America and member of the American Institute of Organbuilders, the International Society of Organbuilders, the Organ Historical Society and the Association Aristide Cavaillé-Coll. He serves on the advisory boards of several organ preservation societies. In his 43 years of pipe organ work and research, Mr. Bethards has been a frequent lecturer and contributor of articles to professional journals. A major thrust of his study, including work abroad, has been Romantic organ building in France, Germany, England and America.

Schoenstein & Co. is the oldest and largest organ factory in the Western states. The Schoenstein family has been building instruments for five generations. The firm was started in the Black Forest of Germany in the mid-19th century and in 1877 in San Francisco. In addition to organ building, Schoenstein & Co. does restoration work specializing in historic organs including the Salt Lake Mormon Tabernacle Aeolian-Skinner organ.

 

What do Miracle Whip® and Velveeta® have to do with stop lists and pipe scaling?  Not much. I am thinking more about Robert Armbruster's magnificent NBC studio orchestra that played so brilliantly on the Kraft Music Hall in the late 1940s.  His aggregation stretched versatility to the maximum. In addition to the usual theme, signature, and background music, he had to accompany Nelson Eddy and Dorothy Kirsten in arias from grand opera, art songs, favorites from operetta and musical comedy, as well as popular melodies of the day. The orchestra had to perform overtures and other legitimate repertoire on the same airwaves as the NBC Symphony and also make a good showing against popular orchestra leaders such as Paul Whiteman. All of this was done within the confines of a modest-size studio and the well-controlled budget of a broadcast that had to pay its own way. Does this sound familiar to those involved in planning for a church pipe organ? To me, it is directly analogous to the age-old quest of providing cathedral music in a parish church setting. Getting the most out of a limited number of stops has been a fascinating challenge and, when successful, a point of great pride for organ builders over centuries.

How did Robert Armbruster and his many colleagues in the fields of broadcast, motion picture, phonograph recording, and theater music bring the grandeur of the symphony orchestra to their audiences when budget and space were limited? It seems quite obvious that they analyzed the major effects produced by the full symphony orchestra and developed patterns of reduced instrumentation that captured the most important ones. A typical radio orchestra of the day might be composed of two flutes (one doubling piccolo), two clarinets (one doubling bass clarinet), one oboe (doubling English horn), one bassoon, two horns, three trumpets, two trombones, one tuba (bell-front recording type), one harp, two percussion (one traps, one tympani and mallets), eight violins, three violas, three 'cellos, and two basses. Sometimes for popular music two or three of the woodwind players would double saxophone. Piano (doubling celesta) and guitar might also be added. These jazz effects were strictly secondary. The orchestra was expected to sound symphonic, and did so at  less than one-third the size of a full symphony orchestra.

The string section in such an orchestra was just large enough to create a rich, full and luxurious sound. At least one of every woodwind tone color was represented. The brass section was larger than necessary to balance the number of strings and winds; however, it was vital to have brass power in reserve to provide the climactic crescendo that could not come from other choirs of the orchestra without far more players. In other words, brass was dominant in the tutti. Solid, powerful bass is an important component of the symphony orchestra, and the tuba was often more important in the role of doubling the string basses than in playing the bottom brass line.

Of course a cleverly worked out list of instrumentation is not nearly enough. Each instrumentalist must be capable of producing exquisite tonal color and have absolute control of dynamics, attack, accent, and release. I don't know of any effect more thrilling in music than hearing one of these great Hollywood orchestras performing at the height of the mid-century period when art music was considered appropriate as mass commercial entertainment. The world's greatest musicians were gathered in Hollywood. They played with a degree of self-confidence and authority that elevated these rather modest ensembles into the major leagues.

Many organ builders, ourselves  included, strive to produce small organs which do big musical jobs. Our choir organs in the French Romantic style and Multum In Parvo (much from little) parish church organs in the English style have captured the essence of comprehensive church organs in extremely small formats. A few years ago we set out to expand this concept with an effort to produce the major effects of the symphonic organ with a limited number of stops. It was conceded for decades that an organ could not be considered symphonic unless it had at least three manuals and 50 or so stops and those who advocate giant instruments--the bigger the better--would scoff at considering anything under 100 ranks symphonic. We came to the conclusion that much of the material in large symphonic organs, although sumptuously beautiful, was duplicative. But even after eliminating duplications, a symphonic stop list was far too large for the average church. We decided to follow the Kraft Music Hall model--analyze the major effects of symphonic organs and see if they could be reproduced in miniature. Obviously it would require more than just a few stops, but we felt that the job could be done with less than twenty.

Before going further one might question the practical value of this exercise. It is our belief that for most churches the organ can only earn its way if it has enough variety and tonal color and a wide enough dynamic range not only to accomplish the nearly impossible list of church musical jobs, but to prevent boredom from setting in among both musicians and listeners over time. Instruments dedicated entirely to the organ solo repertoire, which is the common approach in small designs, fall short in their ability to do the jobs that most congregations want accomplished. For most churches an organ of symphonic character is the ideal--they want versatility, musical leadership, and emotional connection. But they usually want these in a modest size building and on a budget. So aside from the pure pleasure of solving a musical puzzle, we had a good reason to build the smallest symphonic organ we could. We got our first opportunity in the exceptionally beautiful chapel of the First Presbyterian Church of Spartanburg, South Carolina. Our first task was to delineate the major effects of the larger symphonic organs:

Tonal Qualities

1.              Unison diapason tone of at least two different colors and dynamic levels with chorus work suitable to each.

2.              Flutes of vividly differentiated tone color including one powerful, open solo flute.

3.              Two celeste stops: a pair of genuine orchestral strings, and a pair of soft ethereal voices. Most small organs rely on one compromise celeste pair to do these two very different jobs. Such stops usually tend toward flute or diapason tone. Although they may be attractive, they do not elevate an instrument into the symphonic class.  Keen strings are absolutely necessary, but so are the less assertive, dolce tones. Both should be represented, and the string pairs should be full-compass to low C.

4.              Color reed tone useful in both solo and accompaniment roles.

5.              Heroic chorus and solo trumpet tone. In smaller acoustics, power is best achieved with unison tone of great intensity--not loud, high-pitched mixture tone. The proper character is usually achieved through high wind pressure reeds.

6.              Powerful Pedal bass. The symphonic organ has representatives of each tone color in the Pedal department. A Bourdon is not enough; there must also be open flue tone and reed tone to provide clarity, point, and drama. If possible, 32' tone should be included.

Control Elements

7.              Effective expression. A symphonic organ must be able to produce a crescendo from ppp to fff. It also should be able to produce full organ chorus effects at less than full organ volume. Part of this has to do with the proper terracing of voices, but solid expression boxes with responsive shades are vital, too.

8.              Contrasting expression. There must be at least two divisions under expression for an organ to start claiming symphonic status. In a small instrument as many voices as possible should be under expression. In the symphonic concept, unexpressive voices are a luxury normally reserved for large instruments. In some cases layout demands that certain voices be unexpressive, for example where the Swell must be behind the Great, but this should be an exception.

9.              Precise, responsive, silent, lightning fast key and stop actions and a steady wind system.

10.           A comfortable console well equip-ped with playing aids.

Comparing the lists of orchestral instrumentation and organ stops, let us consider what are the most essential elements of each in addition to the bedrock string and brass sections of the orchestra and the comparable diapasons and chorus reeds of the organ. In other words, what special sounds and effects elevate the orchestra and the organ to the symphonic class or, put more simply, make a small ensemble sound big. In the orchestra, french horn, harp, tympani, and solid bass are vital. In the organ the key elements are real strings, a big solo flute, an heroic solo trumpet and also powerful, clear bass. In the orchestra, players must have absolute control over their instruments or else the conductor will not be able to create grand effects from limited instrumentation. In the organ, the key and stop action, wind system, expression system, and console must be perfectly responsive for the organist to be able to lift the organ to the symphonic level. Just as each member of the orchestra must have developed a beautiful and distinctive sound, so the voicer must give his pipes definite character and beautiful tone.

First Presbyterian Church

Spartanburg, South Carolina

Now let's review the Spartanburg organ stop list to see how it fulfills the symphonic ideal. The Great and Swell each have independent diapasons. The name Salicional may be a bit misleading to those who consider it a member of the string family. We use that name (and the name Dulciana) to indicate stops of the echo diapason class, which is characterized by pure diapason tone of moderate to low power. This nomenclature is quite common on British and continental Romantic organs. On the Great, the 8' Open Diapason is complemented with an independent 4' Principal that is quite narrowly scaled in the bass and tenor progressing upward to more nearly match the scale of the Diapason in the high treble. The Principal is rich in harmonics providing a simple, but quite satisfying chorus effect that also works well with the super coupler. The chorus of the Great is completed with a Mixture. Although it is often very useful, particularly in a small scheme to specify an independent Twelfth and Fifteenth instead of a Mixture, the unique tone color provided by a compound stop is essential to the symphonic ensemble. It is comparable to the difference between a three-violin section in a salon ensemble and eight violins in a small symphonic orchestra. In a scheme of only 12 voices it is impossible to have an independent diapason chorus in the Swell, but the unification of a small scale echo diapason makes a very convincing substitute, especially when the Stopped Diapason is included to provide additional unison weight. Unification works best when it is substituting for stops that would not have a very great scale difference if they were straight. In general, the smaller the unison scale the less difference there would be in its octave and fifteenth. Therefore, the Salicional is a good candidate for such treatment.

This organ has four distinctly different flute tones. The 8' Stopped Diapason is of wood with pierced stoppers from middle C producing a colorful but also solidly fundamental sound. The 4' Chimney Flute is an excellent companion, being of extremely small scale with a light, buoyant and lyrical tone. Its 22/3' unification adds interesting solo colors. The Corno Dolce of the Great is a moderate scale open flute with a 1/4 taper. The Harmonic Flute is a powerful solo voice which ascends in power up the scale. It also adds significantly to the foundation of the Great.

Genuine orchestral string tone is provided by the Vox Celeste (II). These are narrow scale strings of exceptionally keen intonation. The contrasting undulating effect is provided by the Flute Celeste which is paired with the Corno Dolce. It has a smooth, ethereal character with just enough edge to add distinct point to accompaniment lines and, with its celeste, to make a heavenly effect leading into the more pungent strings. It can be drawn on the Swell at both 8' and 4' pitches as a means of beginning the Swell build-up. Introduction of the Vox Celeste (II) with swell box closed is hardly noticed when it is preceded by the Flute Celeste at 8' and 4' pitch, the Great box having been opened. Although to many it would seem to be an impractical luxury to extend the Swell Vox Celeste to 8' pitch and also include an ethereal celeste on the Great, we believe that it is one of the basics for the symphonic effect.

For a color reed in this instrument we selected a Flügel Horn--truly a chameleon among stops. It sounds like a small scale or muted trumpet. In certain registers, especially when doubled by a flute, it can produce a French Horn character, and it also serves all of the traditional accompaniment and solo roles of the Oboe. E.M. Skinner often preferred a Flügel Horn in place of an Oboe on small stop lists because of its versatility. The color reed was placed on the Great both to provide mild chorus reed character for that division and so that it can be accompanied by Swell voices.

Chorus reed tone is provided by the Tuba Minor. Traditionally, the name tuba is applied to trumpets or trombas of exceptional power. The trumpet-type is brilliant, singing and bell-like in its tone while the tromba-type is darker, more sonorous and smoother. The tuba in this instrument is definitely of the trumpet class. It is voiced on 8” of wind pressure and is enclosed separately within the Swell box producing double the normal dynamic range.  Its shades are kept partially closed when it is serving in the role of a standard chorus trumpet. When its shades are closed it can play the part of a color reed, the volume level being like that of an oboe. When its shades are fully open this stop takes on an heroic character suitable for trumpet tunes, fanfares, and the like. When played on the Swell manual at 16' and 8' with the super coupler, it provides a thrilling full Swell effect.

It is unusual in an organ of this size to include three 16' Pedal stops, but these are vital if the organ is to be lifted out of the small organ class. A normal 16' Bourdon is augmented by the 16' Corno Dolce which is scaled so as to produce a very prompt-speaking clear and firm bass. It has a reduced scale in the bottom two octaves to produce the kind of bite one hears from the orchestral double bass. The profundity of the Pedal comes from the full length 16' extension of the Swell Tuba.

All of the voices of this organ are under expression. The Great and Swell are located next to one another and speak into the chapel through a ceiling grill. Swell shades open nearly 90˚ and are operated by a powerful, fast electric-pneumatic motor. It would be impossible to create a symphonic caliber dynamic range on an organ of this size without at least one powerful stop under double expression. Described above, this device increases the organ's dynamic range from mp to pp and at the other end of the spectrum from ff to fff.

The action system employs the Schoenstein individual valve Expansion Cell wind chest and the wind system uses five separate regulators to provide absolutely steady wind of adequate capacity and appropriate pressure. The console includes a solid state capture combination action with 16 memories and our Range feature which permits the organist to program pistons to be either generals or divisionals in any combination desired.

This organ has proven to be versatile far beyond what one would expect of a 12-voice scheme. In the context of a modest sized room, the organ is truly symphonic in character and has proven itself capable of playing most of the standard organ repertoire as well as sophisticated choir accompaniments and service music. The main characteristic that separates it from other organs of its size is the number of tone color possibilities and the impressive dynamic range. It is capable of a sustained uninterrupted crescendo from ppp to fff providing a sense of grandeur that is seldom heard even in instruments much larger. This also means that it has met the goal of any good accompanimental organ design: to have a variety of tonal colors available at any volume level the conductor desires.

University of St. Thomas

Houston, Texas

Our next opportunity to test this concept came at the University of St. Thomas in Houston. We were especially honored to work with architect Philip Johnson in designing an instrument for his striking chapel of St. Basil. The building promised an outstanding acoustic and perfect placement, which enabled us to work on a slightly larger format. Since there was to be a display pipe façade, we added an unenclosed First Open Diapason to the Great that is extended into the Pedal providing a fourth 16' Pedal stop on this 15-voice instrument. At the request of our client, we substituted a Clarinet for the Flügel Horn. Although we gave up the mild secondary chorus reed tone character of the Flügel Horn, we gained a color of more contrast with the Tuba. In the Swell we added a unified echo principal mutation at 22/3' and 11/3'. This stop is scaled to balance with the Salicional and augment the organ's secondary chorus as well as provide several options for additional color. The most significant change was to place the keen orchestral strings on high pressure in the secondary Swell expression box along with the Tuba. This is a great advantage for it allows the strings to be muted to various volume levels to serve in more accompaniment roles. Obviously, the build-up of celeste tone is quite enhanced. This also illustrates the value of the opportunity to work with an architect in designing an ideal organ space. In Spartanburg there was no way to enlarge the double expressive box, but in Houston we could tailor make the space to suit the optimum tonal design.

Grace United Methodist Church

Greensboro, North Carolina

Our next instrument along these lines at Grace United Methodist Church in Greensboro, North Carolina, provided a real challenge in placement. Although the side chancel chamber was of adequate size, the opening only spanned about half of it and could not be enlarged. This meant that the Great would fill the opening and that the tone of the Swell would have to speak across the Great and make a 180-degree turn to reach the nave. Obviously we could not enclose the Great, so we cut it back to the bare essentials and built up the Swell, duplexing several of its stops on to the Great. This plan was used with great success by E.M. Skinner in his small schemes. The Harmonic Flute, with its ascending increase in treble power, is one of the few solo voices that can work well unenclosed. Since the Corno Dolce and Celeste had to be in the Swell in order to be under expression, there was no room for its 16' extension, and the Harmonic Flute had to have its own bass. We have often noted the interesting musical quality of the orchestra's traverse flute, which changes to a distinctly string quality in its lowest range resulting from the tube of the flute being the same scale for its entire compass, and we decided to extend the Harmonic Flute into a string-scale bass stop at both 16' and 8' pitch. We reduced the diameter of the pipes as they progressed downward so that the tenor and bass of the Harmonic Flute is distinctly in the string family--enough so to name the extensions 'Cello and Double Bass.

The Great chorus, being unexpressive, required special treatment. An independent 2' Fifteenth completes the chorus, but Mixture tone is also necessary. In an organ of this size, Mixture tone is most useful when it is under expression, so we increased its size and power, placing it within the double expressive sub-division of the Swell. Used with the tuba it adds brilliance to the full Swell build-up. Used alone it can be adjusted to various different volume levels to suit lesser Swell combinations. In full organ combinations, when coupled to the Great, it tops off the diapason chorus.  After seeing the utility of four 16' Pedal stops in Houston, we wanted to do the same here. Fortunately the chamber was large enough to include a 16' extension of the Great Open Diapason. Since the stop did not have to be on display, we were able to make it of wood which yields a very solid, prompt-speaking tone.

Because this organ replaced an older instrument which had a very nice Vox Humana on its own chest, we were able to include this luxury economically. Being in the double expressive section adds to its exotic effect.

Grace Episcopal Church

Sheboygan, Wisconsin

Our next small symphonic organ was built for Grace Episcopal Church in Sheboygan, Wisconsin, an Anglo-Catholic parish that enthusiastically supports the highest traditions of Anglican music. The instrument was designed specifically to accompany the Anglican choral service. This musical emphasis combined with space restrictions in the small gallery dictated some variations on the symphonic theme. First, we substituted the Aeoline and Vox Angelica for the Corno Dolce and Flute Celeste. To make the absolutely smooth, unbroken build-up so beloved in this musical tradition, both celestes are in the string family. The Aeoline and Vox Angelica are keen but very delicate and blend perfectly into the powerful solo Gambas with both inner and outer shades of the Swell closed. Space and budget allowed the luxury of two color reeds so we could have our cake and eat it too with both Clarinet and Flügel Horn.

The lovely church lent itself to a victorian Gothic façade with decorated front pipes. This, in turn, gave us the opportunity to put two Great stops in display--the first Open Diapason and Harmonic Flute with its 'Cello and Double Bass extension. These stops can be accompanied with stops in their own division by using the Enclosed Great to Swell coupler.

The Swell box was not large enough to include open 8' bass pipes; therefore, we provided two unison stops, an open wood Claribel Flute and our very small scale English-style Lieblich Gedeckt sharing a common bass. The Swell has an independent 4' Gemshorn (a tapered principal) and 2' Fifteenth along with principal scale Quint and Tierce mutations to complete its chorus.

Using pipes from the former organ gave us the luxury of two independent Pedal stops making a total of five 16' stops in a 20-voice organ! This yields a reed, an open wood, a moderate scale string, and two levels of bourdon tone, the extremely soft character of the enclosed Lieblich Gedeckt being helpful for accompanying the more delicate sounds of the organ.

St. Paul's School

Brooklandville, Maryland

Our latest example was just completed for St. Paul's School in Brooklandville, Maryland. This large Episcopal school has an attractive, new, collegiate-style chapel. The organ is located in a chamber above the narthex providing plenty of room for a complete exposition of this style. It combines and expands upon the designs of the earlier organs. The only unenclosed stop is the Grand Open Diapason, the bass of which is wood located horizontally on the roof of the expression boxes. The 4' Chimney Flute and Tuba from the Swell are borrowed onto the Great. An Oboe is added to the Swell giving this scheme the two most basic color reed tones. Most important, however, is the provision for a true 32' stop extending to low G. Although this is not part of the initial installation, space is prepared.

A review of these five stop lists shows that although musical, acoustical, and placement considerations must be taken into account if each installation is to reach its maximum potential, a basic design concept adhering to specific design criteria can be maintained. Our objective with each of these jobs was to preserve the symphonic character that was so attractive to our clients as they auditioned similar instruments and at the same time tailor a design to meet their requirements and space restrictions. This is the continuing fascination and challenge of organ design. The satisfaction derived from it is quite similar to the exhilaration an orchestrator feels when his work has yielded a sound that should only come from an orchestra two or three times as large. I'll bet Robert Armbruster enjoyed the playbacks of his Kraft Music Hall performances with the same relish we experience on hearing fine artists play one of these miniature symphonic church organs.
