Chevy Chase, Maryland

From the organbuilder
St. John’s Episcopal Church, Norwood Parish, is located just minutes away from Washington National Cathedral on the border between Bethesda and Chevy Chase, Maryland. St. John’s began in 1873 as a small mission congregation in what was then rural Bethesda. By 1895, the church had been elevated to parish status within the newly formed Diocese of Washington. Throughout its history, St. John’s has been dedicated to “building community at the crossroads of faith and life.” Today, the parish continues to honor this tradition by offering beautiful, liturgically oriented worship services and by providing a wide variety of programs that minister to the diverse needs of the congregation and community.
Prior to the renovation of St. John’s 500-seat Georgian-style sanctuary, the nave presented a feeling of light-filled openness, while the deep and narrow chancel appeared both dark and restrictive. In typical fashion, choir stalls were divided on both sides of the chancel, with the high altar placed against the front wall. The existing organ consisted of three manual divisions with the Great, Swell, and Pedal installed in chambers along the east wall, and the Choir placed on the west wall. Throughout its history and despite the best intentions of the parish, the organ suffered several major incidents involving water damage. With the east wall of the chancel positioned directly beneath the bell tower, it was determined that the tower was, in fact, the root of the problem. Although the tower had previously undergone extensive renovation, water was continuing to find its way into the chambers. At the urging of then director of music Douglas Beck, an organ committee was formed and charged with the task of identifying possible solutions. The committee was also asked to investigate and recommend several organ builders. The committee also felt that it would be wise to engage an organ consultant and did so by involving Donald Sutherland from the Peabody Institute. The initial findings of the committee can be summed up in the following two recommendations. First, the repair of the existing organ would not represent a sound artistic or economic option. Second, a new instrument should not be returned to the existing chambers. Based on these parameters, the committee proceeded to identify a select group of organ builders and to ask each builder to submit their vision for an instrument that would not only meet the liturgical requirements of the parish, but allow the parish to further expand its role in offering artistic expressions of faith to the greater community.
As discussions continued relative to the placement of the organ, it became increasingly clear that installing the organ in any other area of the sanctuary would require changes to the structure of the building. It was also at this point that the clergy and many of the parishioners suggested that the parish consider a comprehensive renovation of the chancel. Given this suggestion, a second committee, called the Architectural Review Committee, was formed to oversee the process and to investigate potential architects and contractors. With the selection of Kerns Group Architects and Forrester Construction, the “ARC” noted that a final decision regarding an organ builder should be made so that all parties could work in a collaborative fashion. On the recommendation of the organ committee, Berghaus Pipe Organ Builders, Inc. was selected to build the new instrument. Recognizing that the combined project including renovations to the building and the construction of a new pipe organ would require a significant financial commitment, St. John’s vestry authorized the formation of a third committee to oversee the fund raising process. The combined efforts of the Organ Committee, Architectural Review Committee, and the Capital Campaign Committee were incorporated under the theme “Enhance, Renew, Rejoice!”
Early in the process of examining the space, it was determined that placing the organ in the gallery would be difficult and limiting. The lack of height and depth would require that the entire rear portion of the church be rebuilt. There was also a great deal of concern expressed about the necessity of moving the choir to the gallery. Although some members of the parish had initially favored this approach, they quickly grasped the complexities involved and shifted their support to the possibilities represented by the chancel. Above and beyond the issue of the organ, enhancing the worship space was an important ingredient in St. John’s view that worship should involve a greater sense of community. One option was to open and enlarge the chancel, creating an inviting space for various forms of worship. Another was to bring the altar forward and install a new communion rail such that it would bring the communion experience closer to the congregation and enable more of those present to take communion at the rail. The ARC was also hopeful that natural light could find its way into the chancel so that the space would have the same warm, inviting feel currently attributed to the nave. This eventually led the architect to modify two of the former organ chambers and add skylights so that the chancel is bathed in soft, natural light. Another transforming suggestion involved moving the choir out of its traditional split arrangement and facing them towards the congregation. With the adoption of these suggestions, it was decided that the ideal placement of the new pipe organ was along the central axis of the building. The new organ would thereby occupy approximately 12 feet of the existing depth at the front of the chancel. This effectively moved the chancel forward placing parishioners, clergy, musicians, etc. in closer proximity. Obviously this change also provided the means for both music and the spoken word to be heard in a clear and full fashion.
St. John’s began its journey to rejuvenate the life of the congregation not only by overhauling the chancel and replacing the organ, but also by enhancing and renewing their relationship with the Creator. Staying close to its roots as a mission congregation, the early parish embraced a low-church form of worship. In the 1970s, under rector William A. Beal, the congregation experimented with a variety of new worship styles, including the Episcopal Church’s trial liturgies. This “new tradition” included the use of the 1979 Prayer Book. The move towards higher church expression continued into the 1980s and 1990s under Rev. Duane Stuart Alvord, and continues today under the leadership of the current rector, Rev. Susan M. Flanders, and the associate rector, Rev. Harrison West. The beautiful construction of the current worship form and the growing excellence of the music program as initially developed under the auspices of former director of music, Douglas Beck, and built upon by the current director of music, Anne Timpane, made it apparent that the new instrument would be required to provide ample support for congregational singing, but must also be an instrument that supports the Anglican choral repertoire. The organ committee’s visits to a wide variety of instruments across the full spectrum of builders pointed to the fact that the parish desired an instrument of great breadth of tone and timbre, with a sound that would fill the space, but not entirely overpower it. It was also important that the organ contain the subtle stops necessary to accompany children’s choirs while having the ability to uphold the congregation with a sense of majesty and power. However, it was also the desire of the former director of music that the instrument should be French-inspired, both in its specification and in its appearance. Given the design of the building, we chose to represent the visual aspect of this request in the design of the console.
The new Berghaus pipe organ at St. John’s Episcopal Church contains 58 speaking stops and 63 ranks over three manuals and pedal. The placement of the instrument along the central axis of the nave allows for optimal sound projection while enhancing the visual impact of the chancel space, most notably as natural light from the skylights reflects off the polished zinc façade. The painted, incised hardwood case is accented with solid walnut trim and gold-leafed pipe mouths. The case also features columns that emulate the columns found throughout the nave. The layout of the organ was intended to give each division its proper musical placement while providing easy access for tuning and service. The Grand-Orgue and Pédale are situated just behind and at the top of the façade, while the expressive Récit and Positif divisions are at the mid or impost levels. This arrangement establishes a leadership role for the Grand-Orgue and Pédale in accompanying congregational singing, while the Récit and Positif, placed at a lower level, are suitable for accompanying choral literature. Set at the very top of the case is a large semicircular arch that continues the barrel vault design of the nave, and allows for full projection of the Grand-Orgue chorus. While not strictly adhering to a particular historical period, the organ, both in terms of its stoplist and tonal approach, is a synthesis of the classical and romantic styles. This synthesis emphasizes a clear, singing quality in the individual stops, while providing depth and warmth when stops are used in combination. Each division contains a complete principal chorus, characteristic flute stops and a full battery of reeds that range from the very subdued to the fiery. Those who have experienced this instrument firsthand remark on how the organ increases in fullness as more stops are drawn. The favorable, but not overly reverberant acoustic is obviously helpful in this instance. The use of Berghaus custom slider and pallet windchests for the majority of the fluework and for certain reeds allows for a natural, unforced sound that ensures favorable blending qualities and excellent tuning stability. Much of the pipework in the organ is scroll and cone tuned. Stops on slider windchests are voiced on 3¼' of wind, while the majority of the reeds are voiced on pressures that range between 3½' and 4'.
The Grand-Orgue is based on a large-scaled 8' Montre constructed from 75% tin. This stop has a rich, full, singing quality, while at the same time providing articulation and clarity to the rest of the chorus. The 8' Gambe is a soft string with moderate sizzle. When combined with the full-bodied 8' Bourdon, it creates a secondary principal-like timbre. The 8' Flute Harmonique is an open flute throughout the compass and becomes harmonic at g32. It is well suited as a blending stop in the jeux de fonds combination, or as a solo stop when required by the Romantic repertoire. The 4' Flute Octaviante is a lighter and softer alternative to the 8' Flute Harmonique. Mutations in this division are based on principal scales and constructed from 52% tin. These stops are voiced to enhance the harmonic series present in the plenum. When used in combination with the flutes, the mutations provide a lighter, brighter cornet in contrast to the Mounted Cornet. The 8' Trompette is constructed from 52% tin, and contains English tapered shallots. Since the organ has a strong solo trumpet, this Trompette was voiced to blend with the flue stops within the division. The Mounted Cornet is scaled and constructed based on the French classical school. The 8' rank is a bourdon, with subsequent ranks being open. The 13'5' rank is proportionally the largest in scale. This stop, with its compass from c13 to g56, is musically successful in literature ranging from Byrd and Buxtehude, to Couperin and DuMage. The Trompette Royale is the organ’s crowning solo reed. Voiced on 10' of wind, the stop contains resonators that are hooded for maximum projection. Overall, the Grand-Orgue sets the tone of the entire instrument. Its placement at the center of the long axis provides an ideal vantage point for strong musical leadership, particularly in accompanying congregational singing. One stop from the former instrument was used in the new instrument. A 16' mahogany Quintaton was extensively rebuilt and revoiced to add a light 16' timbre to the Grand-Orgue.
The musical demands of the Anglican service require that an instrument have a wide variety of voices and dynamic possibilities, particularly in music for choir and organ. Given this situation, entire tonal divisions were designed to work as a unified whole. The Positif Expressif is also based on an 8' Principal of 75% tin and is designed to function as a secondary chorus to the Grand-Orgue. The gentle and singing nature of these principals provides ideal color for Baroque and Renaissance literature. Because of its enclosed placement, the chorus is extremely useful in accompanying choirs and instrumental ensembles. Flute stops include an 8' Bourdon (wood) and a 4' Flûte à Fuseau. In contrast to the Grand-Orgue, the mutations of the Positif are scaled to blend well with flutes versus principals. The 22'3' Nasard relies on Koppelgedackts in its bass octave. The 2' Quarte de Nasard is essentially a hybrid stop, beginning as a light principal, than taking on a bright flute tone in the treble range. The four-rank 1' Cymbale is useful as a chorus mixture, as well as offering a bell-like timbre to lighter textures. The two reeds include a narrow-scale 8' Trompette designed to blend with the principal chorus and an 8' Cromorne, which can be used successfully in either classical or romantic repertoire.
The Récit contains a wide variety of stops, each with its own unique construction. The Salicional and Voix Celeste are small in scale and slotted to give the pair a decidedly French sound. The 8' Flûte à Cheminée features long, wide chimneys for optimal harmonic development. The 4' Flûte Conique is of the Spitzflöte variety and is made of 40% tin. Perhaps one of the most unique stops is the 2' Flûte à Bec, or Block Flute, which incorporates large-scale pipework. Another unique feature of the Récit is the ability to combine the 8' Flûte à Cheminée with the 8' Voix Celeste. The separation that exists between the two ranks provides the slow undulating pattern typically heard in flute celestes. Since an 8' Principal does not exist in this division, the five-rank, 2' Plein Jeu is designed to reinforce the 8' and 4' pitches at earlier points than generally found in typical mixture compositions. The 8' Trompette and 4' Clairon are fiery reeds in the Cavaillé-Coll style, featuring ring and nut construction and resonators of 70% tin. The 8' Hautbois is reminiscent of the English variety. The 16' Basson is voiced to add gravity to the Swell reed chorus while introducing a lighter reed character in the Pédale. The entire reed chorus is placed at the back of the expression chamber with reeds voiced on 4' of wind.
The Pédale is based on the 16' Montre located in the façade. Given the variety of independent stops of varying dynamics and timbre, the Pédale division provides unusually full support for the demands of the manual divisions. The 32' Basse Acoustique is derived from the 16' Montre (unison) and the 16' Soubasse (quint). As an alternative to the 8' Pedal Octave, the 8' Cor de Chamois (Gemshorn) is suitable for giving the 8' line a more pointed emphasis, especially in Baroque combinations. The 32' and 16' Bombarde have wood resonators for maximum fundamental.
All aspects of the organ console, including the bench and music rack, were specifically designed for this instrument. The detail associated with the console complements not only the casework but many of the features that exist within the worship space. Since the director of music at St. John’s is both organist and choirmaster, the profile of the console needed to be low enough to allow the organist to direct the choir from the console. The low-profile French terraced design is constructed from solid walnut with added walnut veneers to insure the consistency of the grain pattern. Curved terraces are made from book-matched, burled walnut and are home to the oblique-face, pau ferro drawknobs. Stops are logically laid out with plenum and major reeds to the organist’s right; flutes, strings, mutations, and minor reeds to the left. Keyboards with maple naturals and walnut sharps feature top-resistant touch for maximum responsiveness. To keep the console free of electronic clutter, the memory level, record/playback and clochette controls are contained in a swivel drawer located on the right-hand side of the console.
The blessing of the new Berghaus organ and the newly renovated chancel was presided over by Bishop John Bryson Chane of the Diocese of Washington. In attendance were representatives from the Lift High the Cross Capital Campaign, the Organ and Architectural Review committees, Kerns Group Architects, Forrester Construction, and Berghaus Pipe Organ Builders. The organ itself was dedicated on Saturday, May 10, and featured nine prominent organists from the greater Washington area.
The completion of the organ is the culmination of many years of planning, preparation, and hard work by the individuals and committees at St. John’s, as well as the organ builder, architect, and general contractor. The result of this work is a grand worship space that uniquely fits the needs of the parish, and an instrument that will serve and inspire the congregation as well as the larger community for generations to come. Berghaus Pipe Organ Builders wishes to thank all those who helped make this project possible.

Berghaus Pipe Organ Builders

From the director of music ministries
In January 2007, St. John’s signed a contract with Berghaus Pipe Organ Builders to build a new instrument that would fulfill and expand the music ministry’s mission and vision:

to explore the journey of faith and life through music; unite parishioners . . . by embracing and cultivating talents and gifts . . . enliven liturgy and community, nourish the musical and creative spirit . . .; inspire the people of St. John’s . . . strengthening relationships with God and one another.

St. John’s has had a pipe organ for more than 80 years. Organ music has enhanced important events in the life of the parish, from weekly worship services, to special holiday music, to baptisms, weddings, funerals and other occasions. However, progressive structural deterioration of the existing organ had caused significant wear and damage to the instrument’s infrastructure. The organ became increasingly unreliable, and so the decision was made not only to replace the instrument but also to think creatively about the chancel’s architectural design. Taking into consideration the size of the room, the number of people that the room will accommodate, and the desired uses of the instrument, it was decided to place the new organ on the central axis of the church for optimal sound projection and flexibility within the space. Berghaus worked in conjunction with our architectural review committee to find a harmonious blend of the advantages and challenges associated with the organ placement and chancel reconfiguration. The result is our stunning new three-manual custom-made work of art.
Berghaus was chosen by our organ builder selection committee after extensive information gathering and evaluation of the proposals submitted by several prominent organ builders. Berghaus’s excellent reputation, design philosophy, and character made them the stand out choice for St. John’s. Their attention to detail, dedication to craftsmanship, and ability to work within our timeframe and cost considerations resulted in an instrument that is not a reflection of me, or Berghaus, but of St. John’s and its parishioners.
Through the generosity of our donors, the work of Berghaus Pipe Organ Builders, and the talents of the guest organists who helped dedicate the instrument, we have built an instrument that will enrich our worship and give music to lift our spirits for year to come.

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.

Casavant Frères op. 3837 (2005)
The Brick Presbyterian Church in the City of New York

A brief history of Brick Church’s Casavant organ
Ever since my first encounter with the Cavaillé-Coll archives at Oberlin during my student days there in the early 1980s, it has been a dream of mine to be involved in an organ project that would recreate the sounds of the French symphonic organ in a North American setting. When an anonymous donor came forward to provide funding to replace Brick Church’s long-ailing Austin organ, I knew that the time had come to act upon my dream.
In November 2001, I invited four internationally recognized organ builders from the United States, Canada, the Netherlands, and Germany to bid on a new organ for the Brick Presbyterian Church in the City of New York. I provided the builders with a preliminary specification and design for the organ. The proposed design was strongly modeled after those instruments built in the latter part of the 19th century by the renowned Parisian organ builder, Aristide Cavaillé-Coll. Upon reviewing the proposals from these four organ builders, it was particularly telling that three out of the four builders required the assistance of the pre-eminent Cavaillé-Coll expert Jean-Louis Coignet in order to successfully realize this organ. In July 2002, Brick Church commissioned organbuilders Casavant Frères of Ste-Hyacinthe, Québec, for a new electric slider chest organ of 88 independent stops (101 speaking stops), 118 ranks and 6288 pipes. This organ, with its dual sixteen-foot façades, was installed during the summer of 2005.
As Jean-Louis Coignet writes later in this article, tonally recreating a French symphonic organ in the 21st century is not an easy task. Even for a firm such as Casavant with its long history, the techniques of voicing in this style had long departed the firm. After thorough discussion and experimentation with the Casavant voicers, we finally decided upon Jean-Sébastien Dufour, one of the younger voicers at Casavant, to be the head voicer for this project. Mr. Dufour was the most willing and also the most skilled of Casavant’s voicers to realize Dr. Coignet’s explicit directions. Mr. Dufour was assisted in his labors by Yves Champagne, Casavant’s senior voicer. Jean-Louis Coignet, Jacquelin Rochette (when Coignet was in France), and I carefully guided the voicing process both in the factory and at Brick Church.
The Brick Church project was a very detailed and complex one. I am thankful to the trustees of Brick Church for providing the support for me to travel to Casavant on the average of once every four weeks during the construction of the organ. This hands-on oversight allowed for a most exacting and fruitful collaboration with Casavant. In any large organ project, things can develop that are not planned unless there is continuous and careful oversight. I am thankful to André Gremillet, then president of Casavant Frères, who gave me much freedom to interact with the various departments within Casavant. In essence, Mr. Gremillet allowed me to act as their project director for this project. Such collaboration is rare in the organ industry. Mr. Gremillet also allowed Jean-Louis Coignet to realize his dreams and directives in a manner that had not been afforded Coignet previously at Casavant. The scholarly and artistic interaction between Jean-Louis Coignet, Casavant, and myself on all matters involving this instrument made for as perfect a realization as possible.
The Brick Church commission enabled Jean-Louis Coignet and Casavant to realize, without any compromise, a large, new instrument fully in the French symphonic tradition. Dr. Coignet’s life-long, firsthand experience with the great Cavaillé-Coll organs as expert organier for the historic organs of Paris, along with his encyclopedic knowledge of the symphonic style of organ building, have contributed immensely to the success of the organ both mechanically and tonally. The Brick Church organ has few peers in North America in its ability to accurately reproduce the sounds of the great French organs. This organ also holds a special place in the Casavant opus list. It is the last instrument to be completed by Casavant with Jean-Louis Coignet as their tonal director. Upon completion of this organ, Coignet retired from his position at Casavant and also his position as expert organier for the City of Paris.
This organ, a gift of one anonymous donor, is called the Anderson Organ in recognition of the dedicated ministry of The Reverend Dr. Herbert B. Anderson and his wife Mrs. Mary Lou Anderson. Dr. Anderson was senior pastor of Brick Church from 1978 until 2001.

Notes from Jean-Louis Coignet on Casavant Frères Opus 3837
Designing an organ in the French symphonic style is by no means a difficult assignment. However, building a new organ today in that style is more challenging as it requires using techniques, particularly of winding and voicing, which have not been in customary use for a long time. Fortunately, there exist a few examples of fine French symphonic organ building that can be carefully studied in order to regain these techniques. These few examples remain, in spite of the many misguided alterations that had been perpetrated during the 20th century on many symphonic organs, especially in France.
As soon as I was consulted about the Brick Church project, I visited the sanctuary and evaluated its dimensions and acoustics as well as those of the organ chambers. At that time I remembered what Cavaillé-Coll had written concerning the location of organs (in De l’orgue et de son architecture): “It is noticeable that the effect of organs is largely lost whenever they are situated in the high parts of a building; on the contrary they profit by being installed in the lower parts. The small choir organs give a striking example of this fact.” So, far from considering it a pitfall to have to put the organ in chambers on both sides of the chancel, I took the best advantage of the situation.
After much discussion with Keith S. Toth, whose clear vision and strong determination were so important all throughout the building of Opus 3837, I realized that the best instrument for Brick Church would be an organ fairly similar to the one built by A. Cavaillé-Coll for the Albert Hall in Sheffield, England in 1873 (this organ was unfortunately destroyed by fire in 1937). Another inspiration came from the organ in Paris’s Notre-Dame Cathedral as I heard it in the mid-1950s. It is a shame that this organ, which was Cavaillé-Coll’s favorite, was completely altered from its original tonal character in the late 1950s and early 1960s, as was César Franck’s Cavaillé-Coll organ in Sainte-Clotilde, Paris.
The Notre-Dame organ displayed a unique sound effect. In no other organ, with the exception of the Jacquot organ in Verdun Cathedral, had the “ascending voicing” typical of the best French symphonic organs been so splendidly achieved. In fact, the main features of the French symphonic organs are:
• a well-balanced proportion of foundation, mutation and reed stops
• huge dynamic possibilities made possible by many very effective enclosed divisions
• voicing of flue pipes with French slots—“entailles de timbre” (different from the Victorian slots used in some Anglo-American organs) and with nicking sufficient enough to prevent any “chiff”
• a winding system that utilizes double-rise bellows
• ascending voicing with full organ dominated by the reeds

Building process of Opus 3837
Specification: The first step consisted in establishing the final specification of the instrument. It was based upon the preliminary stoplist prepared by Keith Toth. The main change from Mr. Toth’s specification was dividing the Grand-Orgue into two parts, Grand-Orgue and Grand-Chœur, in order to gain more flexibility. This is something that Cavaillé-Coll had done in his most prestigious organs. So, the Brick Church organ has actually five manual divisions. The “chœur de clarinettes” in the Positif as well as the various “progressions harmoniques” are features that were typical of the organ in Paris’s Notre-Dame. The Grand-Orgue Bassons 16′ and 8′ were also inspired by that organ, as well as the independent mutations of the 32′ series in the Pédale.
Apart from the stops peculiar to the French symphonic organ, the Brick Church organ offers a few special effects that were not known in France in the 19th century. Three ranks of pipes (Flutes douce and céleste, Cor français) made for the 1917 Brick Church organ by the esteemed American organ builder Ernest M. Skinner, an admirer of Cavaillé-Coll, were placed in the Solo division. We also retained an interesting Cor anglais (free reed stop) made in Paris by Zimmermann in the late 19th century and imported by the Casavant brothers for one of their early organs. The late Guy Thérien, who built the chapel organ at Brick Church, installed this stop in the previous Austin organ. The Récit’s Voix éolienne is another unique stop that only appeared in Cavaillé-Coll’s large organ at St-Ouen in Rouen. This undulating stop is of chimney flute construction for the most part. Its companion stop is the Cor de nuit. With both stops drawn, a slow undulation is heard. This flute celeste has a haunting beauty not found in the flute celestes of the Anglo-American organ.
Pipework: All the pipework was made according to Cavaillé-Coll scalings; metal pipes are made either of “etain fin” for principals, strings, harmonic part of the flutes, and reeds, or “etoffe” (30% tin) for the bourdons. Wood was used for the bourdons up to B 8′. Wood was also used for the large Pédale stops and for the Contre-Bombarde 32′. For reed stops we used Cavaillé-Coll’s typical parallel closed shallots and also tear drop shallots for the Bassons and Clarinettes 16′ and 8′.
Voicing: Much research on the various voicing parameters was done in order to achieve the desired tone: flue width, toe openings, and nicks were measured on a few carefully preserved French symphonic organs. The slotting was particularly well studied. Thanks to documents from the Cavaillé-Coll workshop in my possession, it was possible to recreate the exact tone of the French symphonic “fonds d’orgue.” In his studies on pipes, Cavaillé-Coll documented this matter quite well: the “entaille de timbre” has to be opened one diameter from the top of the pipe. Its width should be either 1/4 of the pipe diameter for most principals, 1/3 of the pipe diameter for strings and some principals, or 1/5 of the pipe diameter for flutes. It should be noted that the harmonic part of Flûtes harmoniques has to be cut dead length and without slotting (though some organ builders used to make slots even on harmonic pipes). As Jean Fellot very correctly wrote: “Slotting had enormous consequences on voicing. It is not exaggerated to claim that this small detail triggered a real revolution.”
Of particular importance in the formation of our voicing goals for Opus 3837 was a visit by Keith Toth, Dr. John B. Herrington III, and me to the unaltered 1898 Cavaillé-Coll organ of Santa María la Real in Azkoitia in the Spanish Basque territory. This three-manual organ with two enclosed divisions was the last instrument completed under the direction of Aristide Cavaillé-Coll, and was voiced by Ferdinand Prince. Immediately upon hearing and inspecting this organ, Mr. Toth and I knew that our voicing goals were well founded and attainable. Moreover, at the same time, I was supervising the restoration of two little-known Parisian organs built in the symphonic style: the Cavaillé-Coll-Mutin (1903) organ in Saint-Honoré-d’Eylau and the Merklin (1905) organ in Saint-Dominique. This enabled me to handle pipes that had not been altered (both organs had escaped the neo-classic furia!), to note their exact parameters and compare their sound to new pipes being voiced.
Winding: Large reservoirs were used throughout, some with double-rise bellows, in order to ensure ample wind supply. The overall wind system is remarkably stable, even when the “octaves graves” are used, but with a subtle flexibility that enhances the instrument’s intrinsic musical qualities. Wind pressures are moderate (from 80mm on the Positif to 135mm for the Solo Tuba), which accounts for the unforced tone of the instrument.
Windchests: Slider chests with electric pull-downs were used for the manual and upper Pédale divisions. The large basses were placed on electro-pneumatic windchests.
Console: Lively discussions and visits with Keith Toth resulted in an elegant console with all controls readily accessible. The console, with its terraced stop jambs of mahogany and oblique stopknobs of rosewood and pao ferro, is patterned after those built by Casavant in the late 19th and early 20th centuries. The highly carved console shell is of American red oak and is patterned after the communion table in the chancel of Brick Church. The manuals have naturals of bone with sharps of ebony. The pedalboard has naturals of maple and sharps of rosewood.
Expression: The enclosures are built with double walls of thick wood with a void between the walls. The shades are of extremely thick dimension. These elements allow for the performance of huge crescendos and diminuendos.
Conclusion: Such a complex undertaking would have never been successful without the collaborative spirit that prevailed throughout the process and certainly not without Keith Toth’s determination and involvement. In fact, on many points, he acted as a “maître d’oeuvre”—during the phase of preparation, we had nearly daily phone conversations that were most enlightening. His numerous visits in the workshop as the organ was being built proved extremely useful. It was a great privilege to collaborate with an organist who has such a deep understanding of the French symphonic organ. His absolute resolve for only the very best was most inspiring. It is our hope that this new organ will serve and uplift the congregation of the Brick Presbyterian Church and that, together with the magnificently renovated sanctuary, it will enrich New York City’s grand musical heritage.

Glück New York Organbuilders, New York, New York
Union Church of Pocantico Hills, Tarrytown, New York

From the pastor: Our latest chapter When Marc Chagall and Henri Matisse never miss a service, and a church is blessed with a warm, close, and giving congregation, special events in the life of a church somehow become even more special. The commissioning of the Laurance Spelman Rockefeller Memorial Pipe Organ was a remarkable milestone in our history, and a finishing touch to our beautiful sanctuary, 85 years after its cornerstone was laid. The instrument was funded by Mr. Rockefeller’s brother, David, his daughter, Dr. Lucy Rockefeller Waletzky, and other members of the family, supplemented by the generosity of their fellow congregants and friends.
Planning for the organ began several years ago and proceeded at a careful pace. Several organbuilders were consulted before selecting Sebastian M. Glück of New York City. An organist, organbuilder, and preservation architect, he was sensitive to all of our concerns, knowing that his creation could neither upstage our worship nor compete with the peerless stained glass that adorns our landmark church. The long process of on-site voicing and tonal finishing resulted in the “perfect fit” of this outstanding pipe organ. The congregation’s sense of the holy is lifted as the clear tones of the organ fill the space. Praising God in the sanctuary soars here to new heights!
—Rev. Dr. F. Paul DeHoff

From the consultant: Looking forward through the rear view mirror

Building an organ for a small space is a challenge for both design and execution, and these challenges have been creatively met in this installation. The builders have carefully engineered the instrument to fit the space, providing good tonal egress and ample accessibility for ease of tuning and maintenance. The instrument possesses character and a distinctive personality, and the magnificent windows by Matisse and Chagall made it seem fitting to emulate the orgue de chœur of the French tradition. Choral and congregational accompaniments are the important functions of this organ, and it contains surprising resources for playing a considerable variety of organ literature.
Essentially a two-manual instrument, a third manual division has been derived from the tonal scheme through studied extension and duplexing. This “found” Positif adds to the versatility of the organ in which each stop must pull its weight, individually and in ensemble. The success of this master plan is in its careful scaling and meticulous tonal finishing.
All of the ranks embody individual character, yet blend effectively in the total ensemble. Some of the ranks deserve special mention because of their creativity and success in this installation. The 16' Contrebasse gives clarity and definition to the pedal, and in combination with the stopped 16' Sous Basse provides a firm foundation. The Contrebasse can also be used beneath the Récit strings, which have a delightful, sizzling, French edge as well. This is a welcome relief from the ubiquitous 16' Gedeckt extensions found on most organs. As the bass to the principal chorus, the 16' Contrebasse undergirds with clarity. An interesting historical aspect of this stop is that it was typical of French Baroque churches to have a double bass playing with the orgue de chœur for additional sonority. On the manuals, this same rank (playing as the 8' Violoncelle) has a desirable incisive quality that is important for color and contrast in the family of foundation stops.
Another stop that serves multiple functions is the Clarinette. It provides gravity and weight as the 16' manual stop for the Récit reed chorus without competing with the Pédale 16' Bombarde. As an 8' solo stop it is more refined than a Cromorne, but has more color and personality that most other Clarinet stops. This is an effective solution for a small instrument.
The removal of the carpet from the chancel revealed an attractive hardwood floor that adds warmth to the music of the organ and the Union Church Choir.
This project was the outcome of a happy collaboration among organist, organbuilder, and consultant. The congregation and its pastor have been most helpful in making this a successful project with rewarding musical results. I am happy to be associated with this organ installation, from the initial discussions, through the building phase, to the dedication and inaugural recital.
—Dr. Gordon Turk

From the director of music: An about-face in the right direction

My service at Union Church began in 1999 when our last organ had aged precisely 30 years. Replacing Wurlitzer’s 1922 Opus 548, it had been assembled by a local organ man utilizing pipes imported from Holland. Unfortunately, the electric valve action of this heavily unified instrument had not withstood the test of time, and Union Church faced the pressing need to replace its console, relays, and playing mechanisms, as well as address the obvious tonal imbalances. After much discussion, the church decided that a new instrument would be a better investment.
The thin, prismatic sound of the old organ, truly a product of its time, actually required amplification to reach our small sanctuary, and from the outset Sebastian Glück had suggested a completely different approach, based upon his ongoing fascination with the orgues de chœur and orgues de salon of fin-de-siècle France. I had the opportunity to play his Opus 10 at Our Lady of Loretto in Cold Spring, New York, a small new organ in this French Romantic style, and I became convinced of both the concept and the builder.
Our consultant agreed with my stipulation that the instrument should be a worthy vehicle for choral accompaniment. He also concurred that Mr. Glück’s focus on a French symphonic character would serve our worship better than yet another neoclassical design, as it could more effectively support our choir with its abundance of properly scaled unison ranks. We were hopeful that the sound generated in the right chancel chamber would somehow fill the entire room, a feat dependent upon Sebastian’s scaling and voicing, as no changes could be made to the historic building. Ironically, all of these ideals represented the opposite of the situation with which we started!
Mr. Glück and I pored over the smaller documented Cavaillé-Coll designs, and I shared his excitement when he returned from his close examination of the famous Merklin/Mutin organ at l’Église Réformée du Saint-Esprit on Paris’s Rue Roquépine as he prepared for his tonal work at Union Church. Although the prototype instruments by Cavaillé-Coll and Mutin usually found their way into highly reverberant rooms, he was correct in asserting that an organ of this character would bloom with a greater presence in our intimate setting than another neo-Baroque organ.
I am elated that the entire church family and the local organ community have expressed nothing but admiration and enthusiasm for this new musical instrument. Its frank sound and rich color activate every corner of the room without ever sounding “loud.” It is thrilling to launch a virile grand chœur in the context of our worship, and satisfying to employ the fonds d’huit without apology. These marvelous attributes do not preclude the performance of music from other schools of literature, as this organ embraces the components of a respectable plein jeu as well as solo stops and ensembles of great clarity.
I often ponder the fact that our new pipe organ continues to be a gift each and every time it is engaged in its sacred function. I wish to express my sincere gratitude to Dr. David Rockefeller, Dr. Lucy Waletzky, Dr. Paul DeHoff, Dr. Gordon Turk, Mr. Sebastian M. Glück, Mr. Albert Jensen-Moulton and the entire Glück staff, as well as all of the donors at the Union Church of Pocantico Hills who made this amazing instrument a reality.
—Thomas Zachacz

From the organbuilder: A French recipe from an American chef

The Laurance Spelman Rockefeller Memorial Pipe Organ is a 21st-century instrument inspired by the school of organbuilding that flourished late in the reign of Napoléon III and during the first 30 years of the Third Republic. The French Romantic organ is characterized by bold, warm, and rich colors. Despite their strong individuality, these organs’ diverse voices form a cooperative community akin to a superb ensemble of celebrated actors, in which the sum of the distinctive parts is exceeded by the exhilarating effect of the whole.
French pipe organs and music of the period exhibit the same passion and spiritual freedom as the painting, sculpture, architecture, and dance of the era, a phenomenon that has captivated the Rockefellers for generations. The family had commissioned the Aeolian company to build large organs for their homes, so in addition to growing up with historically pivotal visual arts, they appreciated the pipe organ in a secular, purely musical context, in addition to what they heard in church.
I made it clear from the start that this would not be an historical copy. The copyist develops solid technique, but does not always make artistic progress as he reproduces the flaws and limitations of his models along with their glories.
The Rockefeller family and Union Church have consistently managed to balance strong tradition with a keen eye for the new. Since my own mindset has always been on “the cutting edge of the passé,” I felt immediately comfortable with them. I could create something new that still took its cues from the past, and they would understand what I was doing. As Dr. Turk said at his dedicatory recital, the organ comes with its own character, but “it has a definite French accent.”

Historical antecedents of the design
Le Grand-Orgue

The structural blueprint of the Grand-Orgue was influenced by Cavaillé-Coll’s 1879 design for the same division in the II/18 instrument in Le Château du Compte de Liminghe, Gesves, Belgium, an orgue de salon for which Lemmens served as consultant. It struck me as a sensible and still-modern concept for the main division for nearly any school of composition. Such compact specifications usually bore either a 2' chorus member or a mixture, but rarely both. The inclusion of both, to the exclusion of yet another 4' flute, seemed to afford more options for the interpretation of a broader range of repertoire. The Fourniture II–IV begins as a Progression Harmonique, adding lower pitches without breaking, then moves to classical plagal breaks in the treble. With slightly smaller scales and higher cutups, the mixture is one that melds smoothly, adding brilliance and line without the harsh separation one might encounter from a “neo-classical” mixture.
Supplying the fonds d’huit would prove more difficult, simply because of space. While the 16' Bourdon was most often “duplexed” to the Pédale in such instruments, I reversed the procedure, extending the substantial 16' Sous Basse upward, making it available at 16' and 8' pitch. The 8' proved a bit too large for proper balance, so I provided a new treble with narrower scales and higher mouths. The 8' Violoncelle is large, warm, vibrant, and nearly reedy, furnishing the third member of the 8' quartet, but we had run out of room.' The 8' Flûte Harmonique was almost pulled out of thin air. I opted to transmit the Récit 4' Flûte Octaviante an octave lower, with one personal quirk. While traditionally one would build an open wood 8' octave (as opposed to the American practice of switching to non-matching stopped pipes), the compromise was to use the stopped poplar pipes of the Récit 8' Cor de Nuit for the first eleven notes, and then build a single low BB pipe of open spotted pewter to complete the octave. My reasoning? I cannot bear to hear the final left-hand note in Franck’s Prélude, Fugue, et Variation land on a stopped pipe, and I was determined that it not happen here. It is a smaller, less soaring sound than normal, being based upon the Récit scale, but provides an essential component that otherwise would be omitted.

Le Récit-Expressif

The Récit had to be an economically designed powerhouse, faithful to its French spirit without locking out other schools of music. Since the French Romantic tradition is one that specifies a string and its undulant under expression, the effect had to be authentic. There would be no washed out, noncommittal, characterless Violas here. Cutting, pungent, keen, energized strings of narrow scale and high tin content were the order of the day, emitting the tone color known and expected by composers and organists of the era.
Cavaillé-Coll would modify his choir of 8', 4', and 2' harmonic flutes in his small organs, and I did so as well. Still stylistically appropriate, the chimneyed 8' Cor de Nuit is a fine stop for continuo use and vocal accompaniment, and it combines beautifully with the Viole de Gambe and Voix Humaine. The 2' Flûte Conique adapts to all music, from Baroque trios to modern choir accompaniments. While unidiomatic to the size and genre of this organ, the 4' Prestant has proven itself to be indispensable, a tonal anchor for the secondary manual in northern literature, and a binding element for anthem accompaniment.
A shortage of space placed the burden of all reed tone upon the Récit. The “usual suspects” (Trompette, Basson et Hautbois, and Voix Humaine) had to be included, tailored to the intimate church and its non-reverberant acoustic. The first step was to acknowledge that a full-throttle blaze of French reeds would work against our goals, so a bright English trumpet with harmonic resonators fit the bill. Despite its modest scale this voice speaks with remarkable authority.
The 8' Basson et Hautbois is a variation of what I had observed in France. French practice called for single-taper resonators and closed, tapered shallots for the bass and tenor octaves, and stem-and-bell resonators and open, domed, parallel shallots for the remainder of the stop. Such a break would have been abrupt and evident in Union Church’s acoustic, so a structural compromise was struck: Bertounêche shallots throughout, with traditional, coned-in Hautbois resonators for the treble, and stem-and-bell resonators with lifting lids for the 8' and 4' Basson octaves.
The huge, woody 16' Clarinette-Basse is a rarity of great impact if properly scaled, built, and voiced. The inspiration for this stop was Cavaillé-Coll’s 1894 design for the III/46 instrument in the salle de concert in the hôtel particulier of the erudite Baron de l’Espée at 55 Avenue des Champs-Élysées. It was the only 16' manual reed in the organ, residing in one of two powerful Récits.
Half-length cylindrical reeds such as this effectively resonate the fundamental, whereas half-length inverted conical ones do not. It is for this reason that the half-length 16' Bassoon extensions so often built sound weak and thin. I opted for an enormous scale, a world away from the anæmic 16' Dulzians that plagued this nation’s Swell divisions in decades past. Its sound latches on to the 8' Trompette and gives the impression of a 16' Double Trumpet when accompanying English anthems and adds complex color to the ensemble.

Le Positif (perdu et trouvé)

When Union Church embarked on this journey, I maintained the position that I would build a smaller, finer instrument than the one they were using, and that a three-manual organ was not possible; I have seen grand dreams push organ projects to unsatisfactory results, and was ethically bound to protect the clients. As the two-manual design was in the process of refinement, Dr. Turk, Mr. Zachacz, and I collectively admitted that despite the sumptuousness of our little banquet, we still felt pangs of hunger. Could we have a third manual for dessert, even though our stomach was full?
While I could not add a third manual division, I could extract one from the material at hand. Cavaillé-Coll’s designs revealed that there were many ‘givens’, trends, and features within his œuvre, but there were no “standard” specifications, beyond the marketed stock models, which were so often customized for the client. A creative license had been granted.
The 8' extension of the 16' Clarinette-Basse, speaking from the Grand-Orgue in the two-manual design, was the first resident of the new Positif. The mezzo-forte fluework was duplexed to this manual, and two 4' extensions, exclusively in this department, provided it a distinctive timbre and center of gravity. Having lived with this organ since its completion, no one involved can imagine it as a two-manual instrument in light of the returns on this small investment.

La Pédale

Two-manual organs of this style often had pedal divisions borrowed entirely from the manuals. As I had no desire to fall back upon historic precedent as an excuse for absent majesty, I asked organbuilder and consultant Randall Wagner, a longtime friend, to help our firm engineer my desires into the available space.
In addition to the aforementioned 16' Sous Basse unit, there is a 16' Contrebasse, an extension of the 8' Violoncelle. It is built with Haskell re-entrant tubes to save space, and maintains bowing string tone all the way to 16' CCC. The 16' string extension is something I had used in Opus 5, Opus 8, and Opus 9, lending variety, pitch definition, and clarity in lieu of the dull “Echo Lieblich” so often found over the past century.
The 4' Quinzième is an independent principal stop essential to the pedal line. Experience confirms that a 4' pedal voice borrowed from a manual unit interferes with the inner voices of polyphony, contributing to “missing note syndrome” and never quite balancing correctly. When funds and space are rationed, such a measure saves the pedal line.
The 16' Bombarde, with full-length resonators, is an extension of the 8' Trompette. The combined result of all of these ideas results in a more effective pedal division.

The nuts and bolts

The organ’s playing action is electro-pneumatic, combining pitman windchests with individual-pouch unit chests for extensions and duplexed voices. The pipe ranks are planted in major third formation, a centuries-old arrangement that assures both easy access and stable tuning. A turbine located beneath the organ delivers wind at a pressure of four inches water column through single-rise reservoirs, providing a stable, unfailing wind supply, even when the tout ensemble is unleashed. The intake is routed from the church itself for added temperature stability, and the entire organ is built on the same level, with the exception of the 16' octaves.
The console is constructed of mahogany and white oak, bearing manual keyboards of cow bone and walnut. The drawknobs and toe studs are turned from pao ferro, and the pedal clavier is constructed of maple and rosewood. I carved the music desk with a medallion that adheres to this firm’s ideals of “opulent restraint.” It acknowledges 19th-century French harmonium grilles as well as the Art Nouveau botanical forms in Matisse’s rose window, his final work, the design for which he completed two days before his death.
While the console is patterned after the work of Aristide Cavaillé-Coll, there are some concessions to make the contemporary American organist feel more at home, such as the inter-manual couplers front and center, controlled by Skinner-style dominos. The Grand-Orgue is normally played from the second manual keyboard, but the order of the two lowest manuals can be switched to conform to standard 19th-century French layouts. A 256-level combination action provides the freedom of kaleidoscopic registrational changes, so the ventils for the jeux de combinaisons have been foregone.

Where thanks is due

As I said at the service of dedication, my staff does everything, and I do the rest. They are all degreed musicians (oddly, all professional singers) with high standards and amazing work ethics. Albert Jensen-Moulton has kept every single project (and me) on track, and his uncanny attention to detail has enhanced each achievement this company has made since he joined the firm. Dominic Inferrera and Joseph DiSalle were the two principal organbuilding pillars supporting the success of this instrument, and their loyalty is deeply appreciated.
Thomas Zachacz maintains a modest front for somebody who knows as much as he does, and his love for this school of organbuilding and composition surfaces with every discussion. From the start, Tom “got it,” and the process of working for him was not just rewarding, it was fun.
The experience was enhanced by the guidance of a knowledgeable, worldly, and supportive consultant, Dr. Gordon Turk, and when he played the dedicatory recital, it was obvious to all that he understood the nuances of instrument he helped to create.
Pastor DeHoff, the Board of Trustees, and the congregation of Union Church form a rare group of cultured, inquisitive, progressive minds, and their willingness to embrace this project will always remain a notable feature of this period in our lives.
Without the donors, this road would not have been traveled. Without their trust and insight, the results might have been different. Buying a great painting is one thing. Commissioning one from an artist you admire is another. But trusting an unknown to build you a mysterious machine that some time in the future will produce sounds you have never heard takes a good deal of courage. Some of the donors I have met, others I have not, but it is for their trust and courage that I shall always be grateful.

Berghaus Pipe Organ Builders, Bellwood, Illinois
St. Jerome Catholic Parish, Oconomowoc, Wisconsin
Berghaus Pipe Organ Builders has built a new pipe organ for the people of St. Jerome Catholic Parish in Oconomowoc, Wisconsin. Opus 226 contains 53 ranks, 42 stops, and 3,019 pipes. The project was made possible by the generosity of the people of St. Jerome Catholic Parish, as well as other benefactors and contributors from the community.
Plans to relocate St. Jerome Parish began in the fall of 1997 as it became clear that the parish was expanding beyond the physical limitations of their historic downtown church. By August 1998, the parish had purchased 37 acres of land and begun planning for a parish-wide campaign. The school was constructed first, and was dedicated on September 11, 2004. A second parish-wide campaign began in January 2005, resulting in the dedication of the church on November 15, 2008. The new 1,000-seat nave nearly tripled the previous sanctuary’s capacity of 350, and provided the parish with a bright, modern worship space with a more favorable acoustical signature.
From the onset of the project, it was clear the existing 1918 Kimball organ would need to be incorporated into the new instrument to minimize new pipe costs. The two-manual, 15-rank organ, located in the center of the rear balcony, was entirely installed in a case against the rear wall. Despite additions in the early 1980s, the organ was of typical early twentieth-century liturgical design. The stoplist incorporated six stops at 8′ pitch, two stops at 4′, and a 16′ Bourdon in the Pedal. Added ranks included a 22⁄3′ Quinte, 2′ Octave, and Mixture IV in the Great. Original voicing and pressures were retained on the Kimball pipes at the time when the organ was augmented, which did little to bridge the gap between the old and new pipes. Thankfully, the new pipes were under-voiced, which would give Berghaus ample latitude in tonal finishing. Additionally, the bottom octave of the 4′ Flute d’Amour was abandoned, and the pipes were shifted down to create a 2′ Flute in the Swell.
In the new church, the organ was planned to occupy both ends of the nave. Great, Swell, and Pedal divisions would be entirely new, and located in the rear gallery. The Antiphonal division would be installed in one chamber, above and to the left side of the chancel. We chose not to divide the resources of the Kimball, but rather use them to create the new Antiphonal division. Furthermore, the Antiphonal chamber would be situated at the same height as the gallery organ to promote tuning stability.
Special consideration was taken in planning pipe scales for the gallery instrument, with the intent that the Antiphonal organ would not be a dark distraction to the new organ. Our present tonal philosophy reflects an eclectic approach, which is conducive to blending early twentieth-century voicing styles. We took our cues from the best elements of late nineteenth-century English organs, tempered somewhat by elements of romantic French and early romantic German organbuilding. All flue scales in the gallery are variable, changing throughout the compass for acoustic and practical reasons. The result is an instrument that, while separated by distance, successfully works as a whole tonal concept, which in turn is able to effectively provide the combinations necessary for liturgical music and beyond. Differing foundation and flute resources are available for cantorial accompaniment, projecting close to the lectern. The Antiphonal also contains the softest string sounds for tonal effects in anthems and voluntaries. When the full resources of the Antiphonal are coupled to the gallery organ, the Antiphonal “carries” the sound of the gallery organ forward down the nave, while at the same time seamlessly blending with the gallery without detracting from its timbre.

Great
The Great division consists of 15 stops, 16 ranks, and is divided between one large slider chest and one electro-pneumatic chest. The division is located directly above the Swell enclosure, and is based on the 8′ Principal, which is located primarily in the façade and constructed of 75% tin, with spotted metal in the treble. The 8′ Principal is scaled near Normalmensur plus two, which on 80mm wind pressure fills the nave with a warm yet gentle tone. It is voiced full in the bass, and has clarity in the treble to reinforce the melody line. The Principal chorus is complete through a four-rank mixture, and includes mutations that are meant to reinforce the plenum. Flues are primarily in spotted metal with the intent to add warmth to the overall tone, yet allow for brightness in finishing.
Additional 8′ stops (Flute Harmonique, Bourdon, Gemshorn, and Gemshorn Celeste t.c.) complete the standard fonds d’orgue, as well as add the unique flexibility of a third, unenclosed celeste. Tonal considerations were made to allow the scaling of this hybrid pair to be generous, yet with a low cut-up to provide clarity of tone. The 8′ Trumpet is designed with German shallots to provide a blending quality, which is meant to enhance the plenum. By contrast, the horizontal Trompette en Chamade, which is mounted on the front of the case, is scaled and voiced to blend with full organ registration, and can be used as a solo stop for processionals and fanfares. Both reeds are voiced on 100mm pressure.

Swell
The Swell division consists of 17 stops, 15 ranks, and is also divided between one large slider and one electro-pneumatic chest. The division is based on the 8′ Diapason of spotted metal, which provides foundation to a complete principal chorus through the Plein Jeu. The scale of the Swell Diapason is three steps smaller and completely different in tone than the Great Principal. The Swell contains a wide variety of stops, ranging from French-style strings to a liquid 8′ Rohrflöte, which is unified at 16′ and made of wood. Mutations are broadly scaled to provide for a rich Cornet decomposée. We elected to use English construction for the 8′ Trompette in the Swell in order to provide a contrast in tone to the Great Trumpet.

Antiphonal
Restoration of the Kimball pipework involved restoration of each pipe in one form or another. While minor repair and remedial voicing work was necessary, the general pipe-making was excellent. Few pipes had been physically altered in previous rebuild efforts, which allowed for maximum flexibility in finishing. We replaced the leather on the stoppers of all wood pipes, and in the spirit of the original Kimball, we provided twelve bass pipes to the Flute d’ Amour, and returned it to 4′ pitch. We also replaced the low twelve pipes of the Open Diapason, which replaced the badly damaged pipes of the original façade. All spotted metal pipes were dunked in a restorative solution, and fitted with new stainless steel sleeves. Finally, an 8′ Vox Humana was provided by Dr. Lee Erickson, friend to the project.
The 8′ Open Diapason of this division provides the organist with yet another Diapason tone. Made from a high-lead alloy, these pipes provide the tone one would expect from a Diapason of this vintage. The pipes are cut dead-length and scrolled. Undoubtedly they would have been originally over-length and slotted. Deep nicks in the languid and lower lip allow for open-toe voicing, which allows this stop to truly enhance the gallery instrument.

Pedal
Consisting of 19 stops, 8 ranks, the Pedal provides a solid foundation to this full instrument. Through calculated borrowing and tonal finishing, this division provides an ample variety of timbres and volumes. The 16′ Principal in the Pedal division (façade) is made from a combination of zinc and 70% tin pipes, and is finished with a silver-tone patina. The Pedal is further supported by an impressive unit 32′ Kontra Posaune, which is voiced full in order to provide an equal blend of harmonics and fundamental. We used tin-faced German shallots throughout the compass of this reed, which provides unique overtones required to enhance the pedal plenum, particularly when considering this stop will be used in part in cantus firmus.

Chests and wind system
Flue pipes of the Great, Swell and Antiphonal sit on Berghaus slider and pallet chests. Reeds and offset chests are electro-pneumatic action. The entire organ is supported by an interior steel structure, which provides stability while allowing unimpeded access to interior parts of the mechanism. Wind to the pipes is supplied by two blowers—one blower for the gallery organ, and one for the Antiphonal. Our wind system provides absolutely steady wind through a balance of schwimmers and reservoirs. Wooden wind conductors help eradicate turbulence and are effective in eliminating noise. Slider chest wind pressures are 80 and 75mm, while reeds and Pedal are on 100mm.
The gallery organ case and organ console are constructed of maple, and are designed to incorporate architectural elements found throughout the worship space. Keyboards are in bone and rosewood, with African Kewazinga Bubinga stop jambs and coupler rail.

Principia College, Cox Auditorium, Elsah, Illinois, Opus 3838

The history of Principia dates from 1897 when Mary Kimball Morgan began home schooling her two sons in order to give them a “fuller” education than what she found in the public schools in St. Louis. Mrs. Morgan, a Christian Scientist, based her educational philosophy on the writings of Mary Baker Eddy, the founder of Christian Science. Soon, when other parents began to observe the difference between her sons and their children, she was asked to take them as students. In 1898 the name Principia was chosen, and by 1906 the first high school graduation was held. A junior college—one of the first in the United States—was added in 1912, and in 1934 the first graduates of the senior college emerged to begin their careers. Today, although it is not an official institution of the Christian Science Church, Principia is staffed by Christian Scientists to serve Christian Science students from infants through adults. Principia maintains two campuses. The college itself is magnificently located on limestone bluffs overlooking the Mississippi River in Elsah, Illinois.

The architect for the college campus, Bernard Ralph Maybeck (1862–1957) of San Francisco, California, was retained in 1923 to prepare a master plan. He decided to use an English village as the inspiration for his creation, to which he referred as his “favorite child.” Construction began in 1931 during the Great Depression, and by 1935 the college moved to the new location in Elsah. In 1993 the Principia College campus was granted National Historic Landmark status by the United States Department of the Interior for its unique plan and distinctive original buildings.

A large auditorium was constructed in 1964, primarily for the annual Principia Public Affairs Conferences. It was soon realized that a much wider variety of activities were using the building and that a pipe organ would be a valued asset. Detlef Kleuker Orgelbau of Brackwede/Westfallen, Germany, installed a two-manual, 32-rank instrument with electric-slider action in 1967. The organ was mounted on a platform hung from a sidewall, the console being positioned in front of stage center. Virgil Fox performed the inaugural concert. Various mechanical problems developed within a short period, and the tonal quality of the instrument proved to be inadequate for the size of the auditorium. Principia decided in 1983 to have the organ rebuilt and enlarged. The result was unfortunately even less successful, both tonally and mechanically, than the original Kleuker. With two failures, the school administration was understandably hesitant to consider another organ project for Cox Auditorium. Yet, a reliable and highly versatile instrument continued to be a demonstrated need for the building. The Music Department, led by college organist Dr. John Near, initiated discussions with the administration in 2000 to have several organ builders visit the campus and provide proposals for a mechanical action organ that would reflect many of the tenets found in the organs of Cavaillé-Coll. Casavant Frères was awarded the contract in August 2002 after several individual donors and the college classes of 1952 and 1953 generously provided funding as their 50th reunion gift to Principia.

When the Casavant team of Jacquelin Rochette (tonal director), Didier Grassin (tracker workshop director), and Carroll Hanson (Casavant representative) visited the site for the first time, we clearly realized the challenges that Cox Auditorium would bring. The 1100-seat auditorium is a shoebox-shaped room 180¢ long and 72¢ wide with a rising seating floor and a large stage. Despite the concrete floor and brick sidewalls, the acoustics are fairly unforgiving. This is mostly due to the thin suspended ceiling, heavy stage curtains and padded seats. The proposed placement of the organ at the back of the stage was enough to depress any weathered organbuilder. The instrument would have to share the space with an active ballet and theater program; it would be allowed a strictly limited footprint that could not interfere with the stage lighting; and it would be subject to potential damage due to the maneuvering of backdrops and decors required by various performances. In addition, a thick proscenium dropped about 8¢ from the ceiling at the front of the stage. Seen from the back of the auditorium, the top portion of the organ would have been hidden. Budget and other administrative practicalities did not allow us much leeway.

We walked away scratching our heads, wondering what layout would minimize the effect of this unfortunate placement. We investigated the possibility of moving the organ forward for musical events, studied the floor strength, and researched the feasibility of air cushions. We were ready to try anything in order to get the sound out of the stage.

That is when the ballet program came to the rescue. After a particularly successful ballet evening, the dance group effectively argued that the loss of precious stage floor would drastically restrict the breadth of their shows. The organ had to go elsewhere.

The move off the stage was certainly good news, visually and tonally. We gave a sigh of relief, although the placement question was still not solved. The previous defunct organ was set against the left wall on a small platform, but such a position would not have been adequate for the large three-manual scheme that was envisioned. The college was ready to explore all options. The possibility of adding a side extension to the building opened the door to a viable solution. It was felt that the organ should not speak entirely sideways to the audience, and sketches were prepared to study the feasibility of an angled case whose platform would link with the main stage. It quickly transpired that steel columns supporting the building could be neither suppressed nor moved. This added another layer of technical difficulties, as we would have to build the organ either beside or around the immovable pillars. Any viable solution encompassing a steel column would have to give good access to the windchests and pipework for maintenance and tuning. After many careful studies, we were able to propose a solution in which the organ would be angled by 20 degrees, with the Récit key action trackers brushing past a steel column. The success of the placement would have to rely on the precision of the new building extension and our own manufacturing, as both organ and building would have to fit like hand and glove. It turned out that the construction of the new chamber was superbly crafted under the college’s supervision, and 30' tall walls were impeccably vertical and placed within a quarter of an inch of the required dimensions.

The internal parts of the instrument are organized in two layers: the Grand Orgue, the Positif, and the Pédale upperwork occupy the front section in the protruding casework, while the Récit Expressif and the large pedal pipework stand behind in the new chamber. The organ is set on symmetrical windchests laid out in major thirds from tenor C for the manual divisions. Since the case follows a strict Werkprinzip, one can read the placement of the main divisions on the façade: the Positif, just above the console, is crowned by the Grand Orgue and its Montre 8'; the Pédale is on either side behind the 16' Montre. The Récit division has been split in two sections: the flues, Hautbois, and Voix humaine are at the front, and the battery of 16', 8' and 4' reeds are at the back. The key action has been realized with traditional wooden trackers, wooden squares, and steel rollers. The electric drawstop action is complemented with a generous capture system. The winding is done through large single rise reservoirs and wooden trunks.

The case design itself is a reflection of the very successful Maybeck architecture that graces the college buildings. We tried to emulate the elegant Arts & Crafts feel by mixing strict main lines with gently curved pipeshades. Great care has been given to enhance the verticality of the overall composition by breaking any potential horizontal lines. The case is made of stained solid American walnut throughout, with highlights of natural maple in the pipeshades. The polished tin façade provides a strong contrast with the soft grain of the walnut. The ensemble warmly glows in the auditorium.

Despite its curved drawstop terraces and porcelain stop nameplates, the console is not trying to copy any Cavaillé-Coll examples. The various elements and their arrangement have been chosen for their elegance and feel. It is a play of simplicity and richness with the walnut highlighted by thin strips of ebony. All the electronic controls, with the exception of a small readout, are discreetly hidden behind small doors.

The tonal architecture of the instrument is thoroughly grounded in the 19th-century French tradition. Dr. Near’s passion for French organ literature, especially that of Charles-Marie Widor, had to find a good vehicle through a full and noble sound. Jacquelin Rochette shaped a tonal structure that continues the musical principles set in the highly successful organ of Brick Church in New York City and which serves effectively the immense corpus of the French repertoire. The organ is articulated around a traditional 16¢ Grand Orgue. The Récit Expressif is typical of the large Récit found in late grand Cavaillé-Coll organs, with the exception of the 16¢ Bourdon that Dr. Near preferred to have in the Positif. The Positif is treated more classically with its series of mutations and a large-scale Cromorne. The Pédale is richly endowed from 32' upwards, although it is the division with the most compromises, as the large reeds and stopped flutes have been obtained through extensions.

Thanks to the wealth of foundation stops, many built with “entaille de timbre,” the organ is solidly grounded, and the generous basses contribute a wonderful gravitas to the instrument. Given the musical goals of retaining clarity throughout the entire compass and achieving nice initiation of speech, the mixtures have been purposely kept under control to avoid any aggressiveness. At the same time, though, the large number of reed stops—twenty percent of the ensemble, built with full-length resonators and designed with Cavaillé-Coll shallots—provides a thrilling tutti of great richness without ever being shrill.

This instrument was not without technical difficulties, and we have been fortunate to work alongside a college whose search for excellence has encouraged us to challenge ourselves. This exhilarating experience was greatly facilitated by their continuing support and assistance. A special thanks goes to Dr. John Near for his valuable guidance and his deep involvement during the entire project. Dr. Near will inaugurate the organ on May 11.
