A Concert Organ for the Béla Bartók Hall in Budapest

A Symphonic Organ in the Cradle of the Symphony
The new Rieger Organ in the Golden Hall of the Music Society in Vienna

Introduction
For centuries, Vienna, the capital of Austria, has been regarded by many as Europe’s music capital. It is here that the symphony was developed as a musical form by composers such as Haydn, Mozart, and Beethoven. So pervasive was the symphony in the development of Western art music that it not only dominated creative music-making until well into the 20th century, but also worldwide became the most common adjective describing orchestras and concert halls. It is also used to denote a style of organbuilding that developed towards the end of the 19th century, when organs were often used as substitutes for orchestras, and organ recitals in secular venues usually included orchestral transcriptions. With the fortunes of fashion being cyclical, the merits of symphonic organs were queried in the mid-20th century, often by their detractors. However, in recent years, one has come to realize that their salient qualities can be combined successfully with more traditional organ elements to create instruments of great versatility, warmth and beauty. Such an organ has just been installed in Vienna, the birthplace of the symphony.
Vienna is also the city in which the performance of music was first democratized. In 1812, as a result of cooperation between citizens and the nobility, the Society of the Friends of Music was founded, through which a platform was created for performing concerts by anyone for everyone. Previously, secular concerts of this nature had primarily been restricted to stately homes, so this was the start of Vienna’s world-renowned civic musical life, and of a tradition that continues to flourish.
A major step along this civic cultural road was the building of the Music Society’s concert hall in 1870 on ground that had become available following the demolition of the old city walls. The architect of this building, known locally as the Musikverein, was Theophil Hansen, who also created other impressive civic buildings along the famous Ring Road that replaced the demolished fortifications.
The Musikverein is an imposing building in neoclassical style that houses a number of facilities, amongst which is the Grand Hall that many regard as Europe’s most acoustically perfect concert hall. It is also undoubtedly one of the most beautiful. Its rich decorations and abundant gilding are opulent, yet not overbearing, resulting in the hall being referred to colloquially as the Golden Hall. At the rear of the stage, Hansen designed an organ case that visually forms the hall’s focal point, with a design derived from the form of a Greek temple. Behind this historic façade, a completely new organ has been installed by the leading Austrian organbuilding firm, Rieger Orgelbau (www.rieger-orgelbau.com); the festive inaugural concert took place on March 26, 2011 in the presence of leaders of the Austrian state, church, and civil society. This magnificent instrument complements the fame and beauty of its setting and is a fine addition to the musical infrastructure of a city that is already, world-wide, at the apogee of civic music activity.

Inaugural concert
The inaugural concert was played by the five leading European organists, who, together with two officials of the Music Society, had formed the committee that had awarded the contract to Rieger and overseen the project.
Given the organ’s significant and prominent location, this committee had specified a versatile instrument whose primary focus was for use together with orchestras, both as an instrument within the orchestral ensemble and as orchestral soloist, i.e., a symphonic organ; but also one that would do justice to the ‘classical’ organ literature. For these reasons, the organ was, among other things, to have two consoles—one mobile that could be placed amongst the members of the orchestra, and a second, with tracker action, on the cantilevered balcony above the orchestra.
Following the formalities by the Society’s dignitaries, including a speech by the president of Rieger, Wendelin Eberle, the music-making began. A fanfare by brass players from the Vienna Symphony Orchestra symbolically heralded the King of Instruments into the Golden Hall, there to be enthroned above the stage.
The first recitalist was Peter Planyavsky, former organist of St. Stephan’s Cathedral in Vienna and professor at the Vienna Music University. Planyavsky presented a brilliant improvisation to illustrate a selection of colors from the organ’s vast tonal palette. Being symphonic in character, the organ has a rich variety of possibilities, ranging from the delicately soft to the majestic, and including an array of solo stops—flutes, reeds and mutations.
The second performer was Ludger Lohmann, professor of organ and cathedral organist in Stuttgart, who gave an impressive rendering of J. S. Bach’s Toccata, Adagio and Fugue in C Major, BWV 564, using the attached mechanical-action console. This work demonstrated the beauty of the ‘classical’ diapason choruses that form the foundation of this organ, and combine effortlessly with its symphonic nature. The principal stops of these choruses blend admirably to form one sound and are crowned by glorious mixtures that add brilliance and clarity to the contrapuntal lines of the music without ever becoming overbearing or harsh. The organ’s copious reed stops made it possible for Lohmann to select ones that, in the Germanic tradition, added color while retaining the music’s transparency and lightness of texture. The direct action and responsiveness of the mechanical console allowed the organist to articulate his playing in a way that suited the Baroque style admirably.
Martin Haselböck, internationally known as conductor of performances on original instruments with the Wiener Akademie, recitalist and organ professor, led the audience into the Romantic era with Franz Liszt’s Prelude and Fugue on B.A.C.H. This piece enabled him to demonstrate the organ’s symphonic versatility and ability to swell in sound from the softest whisper to the point where it convincingly fills the hall. Playing from the detached console on stage, Haselböck made the audience forget that a few moments earlier they had been listening to a superb Baroque sound, as they were introduced to rich foundation stops, impressive chorus reeds, and convincing string-toned colors. The full organ’s sound, based on a foundation of 32′ stops, resonated majestically around the hall as the exciting piece came to its conclusion.
The next recitalist, Gillian Weir, the doyenne of English organists, who was honored for her contributions to organ music with the title Dame Commander of the British Empire in 1996, illustrated convincingly how the new organ accommodates challenging 20th-century repertoire by playing Olivier Messiaen’s “Alleluias sereins d’une âme qui désire le ciel” from L’Ascension and “Dieu parmi nous” from La Nativité du Seigneur. Her use, amongst others, of the Swell reeds—with their leaning towards the Gallic tradition—lent authenticity to this challenging music, as did her judicious choice of mutations for solo passages.
Olivier Latry, professor at the Paris Conservatoire and titular organist of Notre Dame Cathedral in Paris, France, played Alexandre-Pierre-François Boëly’s Fantasy and Fugue in B Major and the first and last movements of Charles-Marie Widor’s Organ Symphony No. 5 in F Minor. His faultless and seemingly effortless renderings of these demanding works enchanted the audience. The set of variations contained in Widor’s first movement gave the capacity audience of more than 2,000 further insights into the kaleidoscopic tonal variety attainable from the new Rieger organ.
The state-of-the-art technology of the playing aids, available on both consoles, of which more is said below, made it easy to accommodate the diverse needs of the five organists, who followed each other at the consoles in quick succession. The listener was also left with a sense of admiration for the way in which the organ’s stops have been scaled and voiced. The choice of pipe scales has resulted in the sound having sufficient fundamental tone for what is a very large hall, even when filled to capacity, without becoming turgid; care has also been taken to balance the constituent stops of the various choruses to ensure the seamless blending of their individual components. Furthermore, the voicing has resulted in clean, clear speech and a remarkable purity and evenness in tonal quality.

Tonal design
As mentioned above, the tonal design of the new organ is essentially symphonic. This term implies tonal warmth from a wealth of foundation stops, adequate numbers of which are string toned, a diversity of colors, including imitations of orchestral instruments, a wide volume range, and smooth crescendi and diminuendi. However, this style of organbuilding, stemming from the Romantic period, is also associated with less favorable characteristics, viz. tonal qualities that obscure part-playing in contrapuntal music, inadequate primary organ tone, i.e., insufficient stops of principal or diapason tone, insufficient upperwork and lack of brilliance, sluggish speech that impedes articulation, and thus, overall, the inability to do justice to the compositions of seminal organ composers, such as J. S. Bach.
In designing the Musikverein organ, Rieger was careful to capture the merits of the symphonic style while avoiding the excesses that led to the demise of such instruments in the 20th century. Accordingly, as already alluded to, the tonal core of each division of the Musikverein organ is a finely balanced principal chorus crowned with classical mixtures that impart the silvery brilliance required for playing much of the classical literature. In addition, the organ has three 32′ stops, fifteen stops at 16′ pitch and thirty-six 8′ stops, which in total ensure that its tone has the golden warmth and fullness required of a symphonic organ.
There are 21 reed stops of varying colors and strengths, some—in the Solo division—on high wind pressure; sufficient mutation stops; a mounted Cornet on the Hauptwerk, and the stops necessary for creating a Cornet Séparé on each of the Swell and Solo Organs. The 86 speaking stops are divided over four manual divisions and pedal, three of which (Orchesterwerk, Swell, and Solo) are enclosed to give the maximum possible dynamic range.
The imposing Hauptwerk’s comprehensive principal chorus is matched by a battery of trumpet-toned reeds at 16′, 8′ and 4′ pitch, whose characters lean towards the Germanic. In contrast, the chorus reeds of the large Swell Organ are modestly French in nature.
An interesting feature of the organ is the large Orchesterwerk division that was conceived to house stops that would blend exceptionally with actual orchestral instruments. The Orchesterwerk division has its own pedal stops contained within its swell box, based on a 32′ Subbass, to ensure that the dynamics of the pedal and manual sections are precisely aligned with each other. Although from the specification it would appear that no provision has been made for the traditional Positive organ that many would regard as important for playing much of the classical literature, compensation for this is made on the fourth manual: the Solo division contains a bright secondary principal chorus, alongside the expected solo reeds and flutes.

The organ’s layout
The organ is favorably situated directly behind the orchestra, its close proximity ensuring the maximum possible blending of the sound of these two partners. Physically, the base of the organ is at the level of the conductor’s podium, but is concealed by the raked seating of the orchestral musicians, which visually shortens the actual 36-foot height of the instrument. At the ‘basement’ level, two of the organ’s blowers are situated, as also a number of wind reservoirs and trunking. Above this, at the level of the rearmost musicians, one finds the enclosed Orchesterwerk division and its accompanying pedal section—meaning that there is literally no gap between the orchestra and this part of the organ.
The ‘lower story’ of the organ is hidden behind an elegant white screen, decorated with panels containing pairs of griffons, and is framed by six ornate gilded pillars that lead the eye upwards to the organ balcony and ‘upper story’ that they appear to support.
The main Pedal stops are placed at the lower level on either side of the Orchesterwerk division, with the longest pipes at the extreme left and right, rising up into the upper story, e.g., those of the full-length Kontraposaune 32′. In contrast, the open wooden pipes of the Kontrabass 32′ are mounted horizontally against the rear wall of the organ, behind the Orchesterwerk swell box, with the longest being mitered to fit them into the 30-foot width of the organ case.
The gallery that visually separates the lower and upper stories of the organ case provides the space for the mechanical action console. In order that organists using this console should not be isolated from the sound of the stops on the level below them, tonal passages have been constructed to link the two levels, those from the Orchesterwerk swell box appropriately being fitted with swell shutters.
The Hauptwerk is to be found in the central position behind the façade pipes that were grouped by Hansen into three classical sections (which always have been, and remain, silent). The prominent position of the Hauptwerk, raised above the stage, allows this important division to speak directly into the body of the hall, as is fitting for the core of the organ. Behind the Hauptwerk and to either side are the Swell Organ and Solo Organ, each in their respective boxes. These, together with the enclosed Orchesterwerk division, can be controlled from one swell pedal, thus enabling the player easily to make finely nuanced adjustments to the organ’s volume.
At the top of the organ, behind the façade pipes and partially in the space created by the triangular pediment that crowns the organ case, are a third blower and the wind reservoirs for the Hauptwerk, Swell and Solo organs.

Technical information
As already mentioned, the organ has two consoles. The attached console is made of walnut wood, whereas the mobile console has a black lacquered exterior that allows it to harmonize on stage with members of the orchestra. The key action of the attached console is mechanical, while that of the second, mobile console (which can be placed anywhere on the stage) is electric. In both cases, the stop action is electric. The normal couplers on the attached console are mechanical and the mobile console has additional “unison off” and adjustable “divided” pedal options. On the moveable console, the organist can choose between having the Hauptwerk or Orchesterwerk organs playable from the bottom manual. Furthermore, the mobile console is fitted with an electrically operated, adjustable feature that allows organists to save their preferred positions for the organ bench and the pedalboard in relation to the manuals, and to recall these when required, after which the preferred positions are taken up automatically. The use of these features at the inaugural concert, and the resulting speed with which one organist could follow another, proved their value in a concert hall setting.
A final, unique, feature of the electric console is that the pedalboard and bench can be retracted electrically to the point where the console can be pushed on its platform through the narrow stage doors when not required on stage. In all other respects, including the layout, the two consoles are identical.
The Rieger capture system, Rieger Electronic Assistant (REA), is used in the Musikverein organ, fully at both consoles and interchangeably between them. The system makes provision for 20 individual organists, each having up to 1,000 combinations, the possibility of inserting three additional combinations between existing ones, and the ability to archive registrations for 250 pieces, each with up to 250 registration combinations. The system’s features include, among other things, sequencing, sostenuto, copying, and repeat functions; divisional and general cancels; unison-off options; and four individually adjustable crescendi. The Rieger recording and playback functions, tuning system, transposing facility, and MIDI features are also available.
The organ has 6,138 pipes, most of which are on slider windchests that are operated by a tracker system from the mechanical console and by pallet magnets from the mobile console; some of the largest pipes are placed on auxiliary pneumatic chests. Individual wind pressures are used for the different divisions of the organ and all windchests are divided into bass and treble sections, each with their own appropriate wind pressures. The bass sections are supplied with stable wind from bellows, whereas the trebles are fed flexibly from schwimmer reservoirs. Of the pipes referred to above, 639 are made of wood, with the remainder being constructed of various alloys of tin and lead. The largest pipe is more than 32 feet in length and weighs approximately 880 pounds.

Postscript
Vienna is the cradle of the symphony as art form, and the glorious Great Hall of the Musikverein a venue par excellence for symphony concerts. It is therefore entirely appropriate that the Gesellschaft der Musikfreunde in Wien (the Society of Music Friends in Vienna) should have wanted a secular, symphonic organ for their beautiful hall. They specified an instrument that would match the quality of the world-renowned ensembles and artists that perform in their famous venue, a concert hall organ whose primary function is playing with orchestras, but also able to accompany other instruments and choirs, and at times be a recital instrument. Rieger Orgelbau has met these high (and potentially conflicting) expectations by judiciously combining the positive features of symphonic organs from an earlier era with the time honored attributes of classical organ building, thereby masterfully overcoming the shortcomings of instruments from the Romantic period, and creating a prototype for a second generation of symphonic organs.
The Musikverein organ is not a copy of an instrument from any historical school of organbuilding, but an absolutely modern instrument that draws on the rich values of and experience from different organbuilding periods, and simultaneously leads the art of organ building into the future. Its essence is ‘symphonic’—not by being ‘historic’, but through infusing the term with new meaning. Those involved in the project—the Society of Music Friends, the committee of organ experts, Rieger-Orgelbau—are all to be congratulated on creating a new milestone in the history of organ building and setting the highest standards for concert hall instruments of the future.

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.

Cathedral Church of St. Peter, Regensburg, Germany, 2009
It was an exceptional privilege for us to have been commissioned to build the new main organ for the Cathedral Church of St. Peter in Regensburg, Germany, especially bearing in mind that, in its 800-year history, this cathedral never possessed such an instrument. No less daunting, however, were the challenges of building an instrument of adequate size in a space of such significance for art and cultural history, an instrument that does justice to prevailing musical requirements and expectations, and simultaneously takes into consideration the architectural sensitivities of the magnificent Gothic building.
This is emphasized by the fact that it eventually took 25 years from the inception of this unique project to its actual realization. What was needed was an exceptional constellation of persons with the magnanimity for working together to mutually find the optimal solution, despite differing opinions and priorities.
Naturally, the first aspect is always the question, often leading to controversial debate, on the tonal architecture of an organ. What should a cathedral organ sound like in the 21st century? One must say that there is no single correct answer to this question. And, if the question can be answered at all, it certainly cannot be done in a few sentences. This subject is far too caught up in ideology for that.
Accordingly, together with the members of the international organ committee, we posed a somewhat different question: what should the new organ be able to do and what would be the appropriate musical expectations for the instrument? In so doing, it soon became clear that one would need a multifaceted, versatile instrument that would accommodate our ways of listening to music today, both for liturgical use and concert practice. It is simply a fact that, nowadays—and this distinguishes us from previous centuries—we do not just want to hear the currently contemporary style of music, but enjoy listening to a wider repertoire of good music from the past.
The tonal considerations taken into account for this organ are mirrored, we trust, in the choice and combination of stops, their scaling and voicing, as well as their allocation to the different divisions of the organ. Each of the three large manual divisions is based on a 16-foot foundation, broadened by a large number of variously colored 8-foot stops, an appropriate superstructure of mutation registers, and numerous reed stops of varied timbres.
The dynamic breadth of the instrument is increased by the balance achieved between the stops with their individual characteristics and the enclosure of the “small Great Organ” (i.e., the Positiv) in a swell box. The Solo division complements this musical structure by adding a tonal crown of distinctive solo voices and a powerful ensemble of reed stops. All this is underpinned by a sonorous Pedal division, rich in fundamental tone, which gives the organ a calm, supporting foundation.
Three requirements were set for the exterior appearance of the organ: it had to be in a “modern” style, “as small as possible,” and, for spatial reasons, was not to stand on the floor nor on a gallery, but be “suspended” from the vaulting! These requirements led, after various planning phases, to the design that has now finally been constructed.

Modern
We expressly did not attempt to include elements from the building in the design, but instead aligned the organ’s design to the architecture by creating a structural form emphasizing verticality and radiating lightness. As is easy to see, this meant avoiding visible casework as far as possible. Despite this, following tonal tradition, a complete case of solid oak is hidden behind the pipe façade.

As small as possible
This organ is as small as possible, and simultaneously as large as necessary. With a height of 60 feet, a width of 25 feet and a depth of 8.2 to 13.4 feet, this instrument has majestic proportions. Nevertheless, in the visual space of the cathedral, the organ appears to be made of filigree. The specific, curved and tapering layout conveys to the viewer the impression of an organ case of modest depth but, simultaneously, one incorporating movement. This impression is strengthened further by fan-shaped elements that open stepwise to form the optical basis for the greater part of the façade pipes, in addition to defining the view of the case from below.
The separate tonal divisions of the organ are arranged in five stories, one above the other, with the mechanical console situated in the middle, both for aural reasons and the technical requirements of the key action. The middle of the lowest level is devoted to the Solo Organ, which is flanked on both sides by the windchests of the Pedal Organ. The second level, directly above the Solo, houses the enclosed Positiv Organ and is followed by the third level with the console. The Great Organ (Hauptwerk) is positioned above the console, with the Swell Organ situated in the top story. On looking closely, one can recognize this arrangement of the tonal divisions in the organ façade.
The first of the organ’s two independent wind systems is positioned above the roof of the Swell Organ (right at the top), with the second being positioned behind the Solo Organ (right at the bottom). Separately from one another, the two wind systems provide stable yet natural “breath-like” wind to the upper and lower divisions of the organ respectively.
The organ possesses two independent consoles: the main console integrated into the structure of the organ, and a general console placed in the sanctuary of the church. The two are functionally identical and both can be used for playing the existing Choir Organ (30/II). The main console is provided with pure mechanical key action and mechanical couplers, whereas the complete key and stop actions, and also the control of the organ’s swell boxes from the general console, are purely electrical. The innovative REA (Rieger Electronic Assistant) system, developed recently by us, is used for this.

The suspended organ
As is known, this is not the first hanging organ. However, with its 80 stops and weight of 37 tons, it is surely the largest of its kind. To achieve this, it was necessary to introduce a steel suspension structure into the loft of the cathedral. To this structure are attached the four steel cables, each 1.18 inches thick, from which the organ is suspended, notably without also being attached to the wall. Attaching the organ case to the cathedral walls was not allowed by the heritage authorities, who insisted that the historical structure of the cathedral should not be changed.
Access to the organ’s main console, 49 feet above the floor, presented a further technical challenge. Given the heritage considerations, you have probably already guessed it correctly: there is no such access possibility from the cathedral. After considering the different options, we finally decided to plan for an elevator inside the organ. Now, the organist can “be raised” to the console comfortably in two minutes by the Panorama elevator while enjoying the unique view of the imposing cathedral nave.
The elevator’s 2.6 x 2.6 foot glass cabin is normally parked directly next to the console and is therefore hidden from view. Only when in use is a door on the side of the organ opened, to enable the cabin to move horizontally about 6.5 feet on a telescopic arm, out of the organ case, before descending 49 feet to the floor, without any support except the cable on which it hangs.
In building this unique organ, we have moved a step beyond our previous tonal, creative, and technical traditions. We trust that the exceptional goals we set ourselves have been met, namely, creating an organ that will be convincing for generations to come, and that will, in a certain sense, indicate the way forward; and that its sound and its visual appearance will delight many listeners and visitors and inspire many musicians.
This is the wish of all the employees of the Rieger firm, who spent countless hours creating this instrument.

Designing an organ presents many challenges, many of which are related to making the instrument fit tonally and visually into the building which will be its home.

The sound

Designing an organ presents many challenges, many of which are related to making the instrument fit tonally and visually into the building which will be its home. The challenges connected with our recent installation at Buckfast Abbey, Devon, England, were, in many ways, out of the ordinary. We were asked to design two instruments of considerable size, tonally interconnected, for a building of moderate size and very kind acoustics that amplify sound in a dreamlike fashion. While it was not difficult to design an instrument to play a variety of literature, much attention was required to scaling the sound to the building without sacrificing the proper characterization of the many different stops.

The tonal palette was based on an initial draft by Matthew Martin, international recitalist, former organist at the London Oratory and now Fellow and Director of Music and College Lecturer at Keble College, Oxford. Further adjustments were coordinated between Philip Arkwright, Organist and Master of the Music at Buckfast Abbey, and Fratelli Ruffatti.

The main instrument, of four manuals and pedal, is located on two sides behind the choir stalls and partially on the triforium level (the upper arcaded gallery) above. Specifically, Great, Positivo (in the Italian style, hence the name), Swell, and Pedal are housed inside solid oak cases at nave level, while the Solo division is placed at triforium level, along with a whole series of “special effects” playable from the Positivo, some of which belong to the early Italian tradition.

The second instrument, comprising two manual divisions with full pedal, is located in the west gallery and partially in the triforium level areas that are closest to the west gallery. Two nearly identical four-manual consoles have been provided, one in each location. The difference between the two is that the Quire console is equipped with an electric lift that adjusts the height of the keydesk and stop jambs by more than four inches (10 centimeters). This feature, along with the two height-adjustable benches (one for concert use, and one for teaching purposes), makes it very easy for any organist to find comfortable playing space. 

As G. Donald Harrison, the Englishman who became tonal director of Aeolian Skinner, once stated, “To me, all art is international; one can draw from the best of all countries. I have used the technique at my disposal to produce instruments which I consider suitable for expressing the best in organ literature.” This instrument indeed embraces this philosophy. The requirements for the seven initial worldwide organbuilders that were asked to submit specifications included the need for the instrument to support a wide repertoire of accompanied music, as well as to successfully perform a wide range of organ literature. Such requirements were not taken lightly and, drawing from decades of experience and from different traditions, as Harrison advocated, Ruffatti introduced several tonal features that are new or rare to find in England, with the aim of sparking interest for improvisation and creative registration for the international repertoire. 

It is along these lines that the Gallery Organ was designed. It draws from the French Romantic tradition of Cavaillé-Coll. Dedicated studies were conducted on several organs in Paris and other locations in order to ensure as close a proximity as possible to the Cavaillé-Coll style, by carefully copying pipe measurements and voicing methods, without pretentious claims of authenticity. The instrument is designed as a two-manual, but it can also be used as a large cohesive division, part of which is under expression, that can be played against, or in tandem with, the main Quire Organ. 

Along the same line of thought, the Italian Positivo was introduced in the Quire. With the tonal consistency of an early Italian instrument and the trademark low-pressure voicing, it provides all tonal resources needed to faithfully perform classical Italian literature from the Renaissance up to the early Romantic period, an ingredient that is indeed rare to find in an instrument in England. It is also ideal for playing in alternatim with the monastic choir. This is not just a nice “toy” to have, but serves convincingly as a Positiv division, in dialogue with the Great for access to a broader classical repertoire.

Another note of interest concerns the Solo division, which includes stops that have been drawn from the Skinner tradition, as well as other orchestral stops of Ruffatti design.

One of the aspects characteristic of Fratelli Ruffatti is that we manufacture almost everything in house, including flue and reed pipes. This is the best guarantee for quality control. At the same time, it provides the opportunity to carefully select all the ingredients that are necessary in the mind of the tonal designer. The difference is in the details. Being able to pass any requirements that experience dictates on to the pipe shop enables the voicers to exactly tailor the sound to the room, resulting in that perfect blend for which Ruffatti is famous.  

Versatility is only partially the product of having a variety of stops on hand; what really makes the difference is the ability of each stop to combine successfully with all others to produce countless tonal combinations. Open-toe voicing for principals and flutes is the key, as it favors blending of sounds, as well as promptness and precision of speech, an aspect that is of paramount importance, especially when there is no close proximity of the player to the pipes (as there would be with a mechanical action instrument). An old misconception still flies around, deriving from the early neo-Baroque times of the Orgelbewegung, or Organ Reform Movement of the mid-twentieth century, where the open-toe voicing technique was sometimes used to produce excessively harsh sounds. Open-toe voicing is instead quite versatile, ideal for the effective voicing of a rank of pipes in a variety of styles, regardless of the chosen wind pressures. 

Materials for the construction of pipes include the ultra-shiny alloy of ninety-five percent tin, used for the pipes in the façade as well as for a high number of larger internal pipes. Its structural strength and incredible resonance properties make it ideal for pipes of larger size. Other internal pipes are made with a tin percentage ranging from 75 to 30 percent.

Many pipes are made of wood, including the resonators of the two majestic 32′ reeds, the Bombarde, and the Fagott. Only the finest African Sipo mahogany has been used, varnished inside and out to enhance resonance. The Pontifical Trumpet, which projects horizontally from the front of the Gallery Organ, has highly polished solid brass resonators.

This organ was featured in the press for the first time in the March 2018 issue of the British magazine Organists’ Review with an article by Philip Arkwright, Organist and Master of the Music at Buckfast Abbey. It was inaugurated on April 20, 2018, with a splendid concert performed by Martin Baker, Organist and Master of Music at Westminster Cathedral, which I had the good fortune to witness. The improvisation that closed the performance was stunning: a perfect demonstration of creativity and a kaleidoscopic use of musical color.

The opening organ series also includes concerts by Vincent Dubois, titular organist of Notre Dame Cathedral, Paris; David Briggs, Artist-in-Residence at St. John the Divine, New York City; Matthew Martin, Director of Music at Keble College, Oxford; Richard Lester, international recitalist; and in-house organists Richard Lea and Matthew Searles.

Architecture and technical features

The east and west organs at Buckfast Abbey are aesthetically quite different. The east organ (Quire) is intended to be discreet, as the client’s desire was that the front of the building should not have the imposing presence of an intricate organ design. For this reason we chose a very simple layout for the façade, with pipes recessed into three arches that crown the stalls on both sides of the Quire. The pipes are hardly visible from the center of the building, but clearly show the brightness of the tin they are built from when they are seen from the side.

The central pipe of each bay, with its diamond-shaped embossing, reflects the light in all directions, providing a touch of richness within the simplicity of the design scheme.

The west organ (Gallery) gave us the opportunity to offer a more sophisticated architectural solution. The full visibility of the splendid stained glass windows being paramount, we built two symmetrical oak organ cases against the side walls of the gallery, with tunnels to grant access to the balcony from the doors in the back corners. The aim was for a design of lightness and richness at the same time—not an easy task, as the two qualities are normally in conflict.

To achieve this goal, we chose a case design where the façade pipes are not topped by a ceiling. Instead, there is an alternation between bays having pipes with unobstructed tops and pipes with carved elements defining the top line. The richness is provided by the carving, which is also used to separate façade pipes within the same bay. In the general scheme, it gives visual continuity to the various bays. These elements have been hand-carved from European oak by a gifted artist, from a Ruffatti design inspired by the intricate and elaborate carved wood of the Abbey’s choir stalls. Even the panels of the lower part of the case are enriched by carvings in the Gothic style. 

The sunlight coming through the stained glass windows is reflected by the shiny surface of the tin pipes, adding a touch of color to the façade, an effect that is remarkably spectacular.

The signature Ruffatti horizontal trumpets, with their flared brass bells, extend from the lower part of the cases, projecting their shining beauty into the Abbey’s central bay.

The most frequent comment we have received on the design is that the organ looks like it has always been there. I believe that this is the biggest compliment that can be paid to the designer, because it proves that the organ belongs to the building, without imposing its presence. The initial aim has been reached: a light yet elegant result.

On the strictly technical side, African Sipo mahogany is widely used for functional parts, such as all of the windchests. The main units are of the slider type, which are controlled by solenoids of the latest generation, featuring self-adjusting power for the initial stiffness of the slider movement and reduced power at the end of the travel, for maximum silence.

The twin consoles feature identical controls and can be played simultaneously, as they often are. The control system is operated by the organist from a touch-screen panel, and it offers a large number of functions. The huge memory provides separate password-protected storage folders for many organists, where stop combinations, personal crescendo, and tutti settings can be stored. The system also features, among many other useful tools, a transposer, a record/playback function, and on-board diagnostics, a useful tool for maintenance.

The height adjustment of the keydesk of the Quire console is controlled by a push button, operating a heavy-duty electric motor. Adjusting the level of the keydesk allows maximum comfort for the player, regardless of that person’s physical height and build.

The organ is distributed over several locations and, true to Ruffatti philosophy, uses several different wind pressures to optimize the tonal result of the various stops. As a result, nine separate blowers, twenty traditional reservoirs, and nine schwimmers have been used to provide adequate and stable wind at the many different pressures, ranging from 40 to 185 mm.

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.

Lewtak Pipe Organ Builders, Camillus, New York, 2005

St. Joseph’s Catholic Church “On the Hill,” Camillus, New York


The Church

The history of St. Joseph’s Church in Camillus, New York, goes back to 1852, when the first resident pastor came to the parish and began to care for the religious needs of local Catholics. The original St. Joseph’s Church in the village of Camillus was built in 1867. The congregation eventually outgrew the small space of the old church, and in 1965 construction started on a new building—the cross-shaped church, with parabolic arches rising 90 feet and dramatic windows at the ends of each wing. As is often the case when substantial funds are required for construction, the purchase of a new pipe organ had to wait its turn. The delay turned out to be a long one—almost 40 years!
For years the rich and varied music program of St. Joseph’s Parish was supported by an electronic organ substitute and a Kawai grand piano. During the fall of 2001, an opportunity came along, and finally the decision was made to begin the construction of a new pipe organ that would fulfill the musical needs of the congregation and would aesthetically complete the sanctuary of St. Joseph’s. That year, another church in the Diocese of Syracuse—St. Louis in Oswego, New York—was closed and the pipe organ from this church was purchased with the thought that it would become a jump-board for a much larger instrument at St. Joseph’s.

The Old Organ

The old organ, a tracker consisting of two manuals with 21 stops, was built by Casavant Frères in 1896 as their Opus 69. It was the first organ from this builder imported in the United States.
At the time of acquisition, the Casavant organ was in a state of complete disrepair. It was obvious that a true historical renovation was not feasible for two primary reasons: the cost and the size of the instrument. Even if the parish were to allocate the funds, St. Joseph’s has a cubic volume approximately four times that of St. Louis Church. The volume of sound required to fill this large space could not possibly be achieved from a rather small and softly voiced instrument. With heavy hearts and facing no other options, the old organ from Oswego was dismantled and moved to St. Joseph’s in Camillus. Only the salvageable parts would be used in a new instrument. Virtually all of the old pipework was saved. A total of 1,202 pipes were moved to Camillus, most of which were in shoddy physical condition; some were badly damaged due to poor maintenance and careless handling. For example, an existing Mixture III on the second manual had twelve original pipes missing in the center, the sign of an obvious “tuning accident” occurring many years ago. These were replaced with “stock” pipes that did not make any sense in terms of either scaling or in the proper Mixture repetition sequence. Many wooden pipes also had visible water damage. The same was true for both manual windchests, which were also transported to St. Joseph’s. From four pedal chests only two were salvageable, with the remaining two damaged beyond any reasonable repair.

The New Tonal Design

Even though the old organ had to be dismantled, it became the backbone for—first and foremost—the tonal design of the new instrument. Professor Ulrik Spang-Hanssen from the Royal Danish Music Conservatory in Aarhus, Denmark was consulted, and a plan was devised for the preservation of the original stop configuration, augmenting it with a new third keyboard that would serve as the foundation for the “big sound.” Very few old ranks have been shifted. What was acquired from Oswego became the second and third manuals (Positif and Récit) with some changes necessary to move the timbre out of the dark and 8'-heavy character. The original configuration did not have any fifths or thirds among its stops. In addition, the first manual (the Great) had four 8' stops and one 4' stop; the second manual (the Swell) had a 16' Bourdon and a sub-octave coupler to the Great. New ranks were added with the purpose of not just strengthening the volume, but more importantly brightening the sound of the organo pleno in these two divisions. The old Great (current Positif) received the 2' Piccolo from the old Swell, and the original Dulciana 8' was moved to the new Grand Orgue division. The old Swell (current Récit) received a new Nasard 22?3', Principal 2' and Tierce 13?5'. From the same division, the Trumpet 8¢ and Bourdon 16' were moved to the new Grand Orgue.

The addition of a new first manual (the Grand Orgue) allowed not only for keeping the stop configuration as close to the original as possible, but also opened completely new sound prospects to build on and to draw from. This is the division that is by far the strongest. It is rather basic in terms of utilized ranks, not too far from the tonal character of the old instrument and yet created with the sole purpose of giving a complete Principal chorus to the entire instrument. The Cornet Harmonique III deserves special mention. It is a three-rank cornet (22?3¢, 2¢ and 13?5¢) consisting of widely scaled, overblown flute pipes with two small holes midway through the body length. The aural effect is quite unusual: the cornet combination has a far greater penetration and clarity of timbre thanks to the characteristic “hollow” sound of the harmonic pipes.

Obviously the Pedal division required more power. This was simply achieved by adding to the original three stops (Double Open 16', Bourdon 16' and Violoncello 8') a new Octave 8', Cor de Nuit 4' and a round-sounding 16' Buzène, a reed stop with leathered shallots. It would have been an asset to have a mixture in the Pedal; however, the financial constraints made it impossible. The total number of new pipes added is 1,100.

The New Façade

The difficult task of designing the façade for this organ fell on our shoulders after we approached various outside architects and artists. The problems we encountered with the architects were their lack of understanding the principles of how the organ works, not knowing what is and what is not attainable. There was also the lack of positive and healthy aesthetics. The objectives were quite simple: first, to fit the organ into the arch shape of the ceiling, and second, to show that this instrument blends the old with the new. An additional requirement came from the fact that it had been explicitly requested that the console must stay on the main floor of the church while the rest of the organ rests on a 10-foot high loft. The reasoning for this came from the liturgical documents of the Second Vatican Council, which dictates that the music ministry is not to be separated from the congregation. In the case of a tracker organ, it immediately makes things a lot more complicated simply because the linkage becomes dangerously long.

The design of this church building cannot be classified as “contemporary” but it may be described as “modern.” However, all throughout the building there are many elements of traditional architectural design: harmonious lines, time-honored proportions, and a lot of symmetry. The answer to all of these challenges came from my brother, architect Pawel Lewtak. He is the creator of the design that became a real head-turner among parishioners and visitors alike. In his words, his worst fear was to create another organ that would be sitting “up there” with the console that is placed “down there,” and one has little to do with the other. Instead, he created a homogenous shape that ties the top with the base in a seamless manner. The tower-like structure of segments gives it slenderness and allows for traditional pipe grouping. To reflect what is inside the organ case, the original façade pipes were kept in their distinctive clusters, and new groups of double flamed copper pipes were added. Copper was definitely the material of choice for its perfect blend with the surrounding color scheme.

There is one special feature of this façade that separates it from all others: mirrors, more specifically, forty of them! Hardly noticeable at first glance, they add light, depth, spark, and elegance. The mirrors are only four inches wide, and are of various lengths. They are placed in wooden frames in the spaces between the pipe clusters. They enhance the design by offering a true three-dimensional effect. As people walk through the church they are always viewing a distinctive picture with variegated light reflections, innumerable shadows and highlights, an array of geometrical shapes, yet all elements are well organized with pleasing aesthetic integrity.

The façade is made of white ash with mahogany ornaments, and the case behind it is made from birch and carefully selected white poplar.

The Mechanics and Materials

The key action is purely mechanical. It is referred to as a suspended action and was the only logical choice given our circumstances. Long distance between the keyboards and the windchests dictated absolute precision in the making of the tracker action. The longest linkage run is 33 feet and yet the average weight of the key—when the chests are under pressure—is only 120 grams. The action is not the least sluggish thanks to the employment of a pressure rail on the back of each keyboard with springs that remove some of the key weight. Each division has its own floating rail allowing for climatic changes of the wood of the trackers, which are made of red cedar. The squares are fashioned out of aluminum as are the rollers and roller arms. On the longest rollers, needle bearings were utilized to support the weight of each roller.

The keys are made of tight-grained pine covered with black African wood (grenadilla) for the naturals, and bone-on-maple for the sharps. The cheeks of the keyboards are white oak with ebony inlays.
All windchests are of slider and tone-channel construction. Two old windchests (Positif and Récit) have been completely taken apart and restored to mint condition. In both, the pallets used are of a so-called “relief” type: in essence, each pallet consists of two pieces, one of which is being pulled down first thus releasing the pressure and breaking the initial resistance. After cleaning, releathering and complete re-regulating of all the parts, they work flawlessly. New windchests are made out of select yellow pine and have single pallets in all but the lowest octaves. In the bass, we installed two pallets per tone channel, but with sequential opening, which causes the touch to be the same as the rest of the keys.
Pedal pipes are split diatonically and stand on either side of the case. The open 16¢ flute stands on its own two chests (C side and C# side). The remaining pedal pipes received two new windchests with space for both the old and the new ranks.

The stop action is state-of-the-art electric. The stop plates, made of grenadilla, hide behind them contactless switches. The system offers full convenience of 1,280 memory levels for even the most demanding performer. Half of the levels are lock-protected. The layout of thumb and toe pistons is very simple and offers some necessary redundancy. Couplers can be operated either by thumb pistons or toe studs. Also, the navigation through the system’s memory levels can be done either by hand, by foot or on the side by an assistant. There is one expression pedal for the Récit and a Crescendo pedal. The Crescendo, in order to work, first must be activated by a toe stud. It is fully programmable and has a digital level display from 0 through 30. A similar kind of digital level display is in place for the expression pedal of the Récit. The shutters are operated by a 30-stage, digitally controlled electric motor.

The organ utilizes a three-phase 1.5 hp electric blower with slow RPM. There are two reservoir bellows—one old one and one new— providing ample air supply to the whole instrument. There are three tremolos, one for each manual. Two of them have electronically adjustable speed of undulation right at the console.

The Voicing

Any organ is only as good as it sounds. Therefore, even though we spared neither time nor money on mechanical details, the most important element remained the voicing. All of the old ranks received some sort of voicing re-vamp. They had all previously been voiced down for a much smaller building. We made them more free speaking, definitely less obstructed at the toe. All of the old ranks were heavily nicked, which made things difficult at times. The new ranks were voiced with a little bit of chiff, just enough to make their speech more pronounced in the large acoustics of St. Joseph’s Church. The old reeds needed to be re-tongued in order to gain a larger sound. The Trumpet 8¢, especially, required more brilliance and volume in order to balance well with the rest of the Grand Orgue. The organ is tuned to a Tartini-Vallotti temperament, which gives it a pleasant color and tonal personality. The instrument has much to offer in terms of variety of sound colors as well as the dynamics and individual stop character.



From an organbuilder’s perspective, taking a vintage 1896 organ and bringing it up to present day expectations, and having an organ that could be used for church services as well as concert performances has been a personally demanding and ingratiating experience. In organ building, the idea is always to be creative while retaining the original elements and merging them with new technologies. It is rewarding beyond words when an artist sits down at the console and you begin to see the smiles of pleasure. It means you have accomplished your goal of creating the finest organ from available sources.
Lewtak Pipe Organ Builders wishes to extend our sincere thanks to all volunteers who gave their time and energy to this most worthy project. We also thank the parishioners of St. Joseph’s Church of Camillus, New York, for their continuing understanding, patience and support.
