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.

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.

Burkhard Goethe, translated by Constanze Geiss

Burkhart Goethe, church music director and organ-architect in Schwäbisch Hall (South Germany), was born in 1948. After an apprenticeship for six years (carpenter and organbuilder) with Alfred Führer, Wilhelmshaven, he traveled in Europe working on the restoration of North German instruments. Since 1982 he has been organ advisor of the Protestant church of Württemberg and teacher at the Freiburg National Academy of Music. He is the architect of more than 80 organ cases since 1978. Constanze Geiss is a journeyman organbuilder for Mühleisen Orgelbau in Leonberg, Germany, where she works both in management of the business and in organbuilding areas. She studied at the organbuilding college in Ludwigsburg and completed her apprenticeship with Mühleisen. She worked at the Brombaugh shop in Eugene, Oregon during 1999–2000. Ms. Geiss was assisted in editing the translation by David Petty, organbuilder in Eugene, Oregon. He and Ms. Geiss were colleagues at the Brombaugh shop during her time in the U.S.

In 2003 the Arcadom company requested 13 European companies to design an instrument for the new Béla Bartók National Concert Hall in Budapest, Hungary. Six companies then were looked at more closely; three of them were from Germany. After a series of journeys in order to gain as much knowledge about the companies as possible, the committee (five concert organists) decided to ask the joint venture of the Mühleisen company (Germany) and the organ manufacturer Pécs (Hungary) to build the organ. The two companies were known to each other because of various projects they had encountered with the Fraunhofer Institute, Stuttgart. Prof. Judith Angster, a descendant of the organ-builder family Angster in Hungary, is an acknowledged specialist on physical questions related to the technical parts of organs. She strongly supported the joint venture and was a big help in organizational matters.
The concert hall itself was designed by Gabór Zoboki and was finished in 2005. The fascinating oval building has the dimensions of a large cathedral: it is 25 meters tall and 52 meters long. The building’s interior is covered with wooden panels, creating a warm atmosphere. In order to guarantee an outstanding acoustic, the internationally known American advisor Russell Johnson worked on the design. The principal element is a huge detailed platform in the center of the room that can be lowered completely or in parts, which helps to create a suitable acoustic for special solo concerts. Along the sides of the room, 84 large chambers provide the reverberation needed for organ concerts. Since they can be evenly adjusted, the conditions for the organ builders were ideal.
Finding a musically suitable concept turned out to be more difficult. Two organ advisors with opposing ideas, István Baroti and László Fassang, were a challenge for the organ builders. On the one side, there was the idea of a large Hungarian organ in the style of the 1950s Orgelbewegung; on the other side there was the idea of a modern symphonic concert instrument. More journeys and concerts on various instruments and long discussions were necessary to finally agree on the disposition of a concert instrument.
During the years 2004–2006 the instrument was built by both companies, Pécs in Hungary and Mühleisen in Germany. The case, chests, wind system, frames and structural parts were made in Hungary, as well as all of the wooden and some of the metal pipes. All the design work, construction of coupler systems and details, electric and mechanical stop action, keydesk, reeds, and complete scaling was done in Germany. The Mühleisen Company also was in charge of the entire voicing process, working closely with both advisors. Since the concert hall was heavily used during the daytime, most of the installation and the voicing had to be done after 11 pm.

Façade
As seems to be typical during the last decades, the façade essentially was designed by the architect of the concert hall. Gábor Zoboki at first offered a post-Art-Nouveau-style façade, which would have worked well in the room and also resembled downtown Budapest with its Art Deco style. Unfortunately, the buyers were not convinced and had the Mühleisen company work on an idea of an open façade. The divisions in the back are of course all contained in their cases made of solid wood. The biggest façade pipes are the Majorbass 32? (starting at E) and the Principalbass 16? and Montre 16?, both starting from bottom C, all made of a high tin alloy. On the top (slightly shifted to the back), the Octavbass 8? and the Solo Principale 8? can be seen. The lower middle part (above the mechanical console) contains the horizontal reeds (Chamade 16?–4?). Therefore, the organ builders need not fear that the organ will be covered with curtains as is the case in various concert halls nowadays. The organ stays visible at all times.
The case is made of solid cherry and, in order to break with the strong vertical lines of the whole façade, the pipes of the inside corners of the main groups are slightly tilted towards the center of the organ. This subtle feature is often only seen with a second look.

Technical design
Twelve meters above the orchestra stage, the organ is installed on a large balcony. Its overall height is 15.6 meters, width 13 meters, and depth 4.4 meters. Inside the instrument, a good “infrastructure” made up of large stairs and wide walkboards guarantees good access to every part of the chests and pipes for maintenance. Every detail was planned; no big surprises were left for the people who worked on site.
Chests
The 18 mechanical slider windchests and some 29 single and support chests are positioned on top of large wooden construction beams, along the action lines. Behind the façade of the first story, one can find the Grande orgue. Separated by a large walkboard, the Récit expressif is positioned directly behind it. The Solo and the Positif expressif are located symmetrically on the second story. This whole complex is lined by the Pedal stops on the left and right sides, whereas the largest pipes of the 32? needed to be lowered into the “basement” of the organ.

Wind system
The wind system is divided into two divisions. The Grande orgue, Récit expressif, and Pedal are supplied by two large blowers and six large parallel double wedge bellows, which are built into the base of the instrument. Another blower and bellows on top of the swell box of the Récit provide the wind for the Positif expressif and Solo divisions. A high-pressure blower for the Tuba Mirabilis 8? with 450mm wind pressure is also located there. In all manuals, the wind pressure varies from the bass to the treble. The three 32? stops have their own extra wind supply. The whole system consists of four blowers and about 105 meters of wind trunks made of solid wood.

Action
The new organ in the Béla Bartók Hall has two different action systems. The main (attached) console with its ten couplers is played mechanically. The only exceptions are the Chamades and the 32? stops. The key action is balanced and is supported inside the chests with little pivot-rail bellows. They are also suspended. The fourteen octave couplers and the five Chamade couplers work electrically; the ten mechanical couplers can also be switched to electric usage. The second, detached concert console is exclusively electric; so is all the stop action. Solenoids work the sliders; the preset combination system and the couplers are run by a BUS system.
When the organ was shown to the press, the detached console was not available to be seen. Therefore the author could only feel and play the action of the main console. It is easy and light and allows good articulation on all four manuals. Even when using all mechanical couplers and playing tutti, the pluck stays elegant and precise, due to good coupler construction and well-adjusted balancier support.

Consoles
The main console combines the neat, clean look of a well-designed keydesk with ergonomic standards. The 139 stop knobs are designed as pull knobs. The detached console is a work of art in itself. It is made of solid cherry and shows many round, Art Nouveau-like lines. The pluck of the keys is simulated electrically in order to provide the best articulation possible.

Swell boxes
All walls and the shutters of the swell boxes are made of a special five-layered wall system approximately six cm thick. This was especially developed by the Stuttgarter Fraunhofer Institute. Both swell boxes work remarkably well.

“Hanging” façade pipes
Organ builders are often confronted with the following problem: large pipes are stressed by their own weight, especially around the mouth opening. Therefore inlays, hooks and supports are soldered to hold everything in place. Nevertheless, they often have the tendency to bend or collapse. The ideas of the creative Swabians help to prevent those matters. Already their large instrument in Stuttgart (Stiftskirche 2004 IV/84) was protected by a large contraption to take weight off the foot of the pipe. In three places the pipe is hooked to the top of the room, where it is held by counterweights. That lowers the static weight of the pipe, preventing collapse, and also enables one single person to lift the pipe in its rack.

Tonal design
It is always difficult to describe the sound of an organ. One simply has to hear it. What one can say about this particular instrument is that the tonal design works very well in the given acoustic, which has a tendency to swallow bass frequency pitches and therefore needs good foundation stops. During the voicing process, the scale of various stops had to be enlarged to meet these needs.
The principals, which account for 26% of the whole instrument (with its eight mixtures), are formidable and can fill the hall, but can also show their vocal mild sides. The Montre 16? shows itself very subtly without losing its tonal force. An outstanding stop is the Principale 8? of the Solo manual with its changing scale. It works very nicely in combination with the Voce humana. The separate wind supply of the 32? and 16? Pedal stops gives them remarkable speech in the room.
The 23 reed stops of the organ account for 25% of the stoplist. Not only trumpets and clairons belong to that group, but also five almost lyrical voices and the Chamades and the high pressure Tuba. Producing a highly differentiated and distinct sound is taken very seriously in the Mühleisen company. Many trumpet ensembles and various solo stops such as the Cromorne, Voix humaine, Clarinette and Basson-Hautbois make it a challenge for any organist to exhaust all the color possibilities. The Chamaden division with its Chamades 16?–4? resembles an “ultima ratio” to the tutti. The Tuba mirabilis seems in the British manner, darker and softer but still strong enough to add to the fortissimo of all other divisions. Another outstanding sound of a different kind is created by the Cor anglais of the Solo division. Its silken clarity reminds one of Ernest Skinner’s Orchestral Oboe. It is hard to understand why those fine stops are built so rarely nowadays.
The instrument also includes 13 string stops; two of them are celestes. This is a moderate number (14% of the overall stops), but nevertheless they are very characteristic in sound and can be used in many combinations. The Gamba of the Grande orgue is strong and precise, the Salicional of the Positif expressif soft, the Violon 16?, Geigenprincipal 8?, Gamba 8?, Aeoline 8?, Voix céleste and Violine 4? of the Récit expressif are all very distinct in sound. In the Pedal, the Contrebasse, Violon and Cello make a good ensemble. The presence of the Violon is impressive, its sound very clear.
Flutes make up 18.5% of the stoplist. Those 17 different colors are open, stopped or over-blowing pipes that have a progression in their scaling, following the French tradition to be used as solo voices. Some are built in the German tradition in order to blend and add color. In combination with string stops (for example, the Salicional and the Fl. traversière on the Positif expressif or the Gamba and the Flûte octaviante of the Récit expressif) they sound remarkably good.
The great number of mutations allows building a “Cornet décomposé” in all divisions except the Grande orgue, which has its own large Cornet. Taking a close look inside the Pedal division, one is strongly reminded of Oskar Walcker’s “Grand Bourdon.” The Großquinte (102?3?), Tercsept II (62?5?) and the Zinck III (51?3?) are able to underline the 32? and 16? sounds and have a great presence in the room.
An interesting steel-like, synthetic sounding voice is the Septnon of the Positif expressif, combined with Piccolo 1? and Tierce. The Solo division again follows Cavaillé-Coll’s idea of the “Clavier Bombarde” because its mutations (the Septième 22?7? included) are based on the 16? range. The large room handles all of this easily.
It would take ages in order to try and find all different kinds of registrations. To listen, the best seats are located on the opposite side of the room, in the balcony. It is even possible to hear calm noises or whispering from the console! Bravo to the great acoustics.

Successful joint venture
A great compliment must be given to both companies that have worked to create this wonderful instrument: the Organmanufactura Pécs Ltd. of Hungary and the organ building company Mühleisen of Leonberg, Germany. Both contributed their best creativity and skills. The outstanding quality of the Hungarian craftsmanship, creativity and motivated work attitude strongly supported the design work, organization and the voicing process by the Germans. It is quite probable that in the future, large organ projects will be given to companies that are willing to cooperate. Good communication and well-balanced work attitudes and standards are needed for these kinds of projects. It is of great importance to make agreements and also to draw close lines that each group has to stick to, in order to make things a “snug fit.” Too much back and forth, communicating about the same things all over again, would be too time-consuming. Prevoiced test pipes are hard to e-mail throughout Europe.

Coda
The new instrument of the Béla Bartók Hall in Budapest is definitely worth seeing and hearing. As a “Swabian from the Danube” with its French lifestyle, the instrument suits the great architecture. The inaugural concert featured four organists: Zsuzana Elekes, István Baróti, László Fassang, and Xavér Varnus on May 22, 2006. In June 2006, many internationally known concert organists played many concerts on the organ. Most of them used the detached, electrical console on the stage. Obviously, the possibility of playing in front of the audience is of more importance than the sensitive touch of the mechanical main console. But this also happens in other places, due to the fact that organists like to listen directly to their registrations in advance.
This is one sad aspect about designing and creating an instrument in two ways: having to face the fact that all the extra work and preparations are not honored. One could question the reason for the double construction. Shouldn’t one build symphonic organs completely electrically in the future, since there have been so many inventions lately that provide an almost mechanical touch? This thought obviously would not be the taste of many organ advisors.
Undoubtedly, the mechanical slider chest is a very good solution for smaller and middle-sized instruments. Luckily for recent German organ building, Cavaillé-Coll consequently built these chests during his work life. The primary wish at many times had been symphonic instruments by all means (with Barker levers or electric couplers that are rarely talked about). In the meantime, we can see that there are quite a few good German symphonic instruments from the late 19th and early 20th centuries. There are great instruments with cone chests, membrane chests or various electro-pneumatic inventions that are not mechanical slider chest systems.
However, many large organ projects are requested to have slider chests (single-lever keys preferred), Romantic, symphonic layouts and everything that goes with it. This creates many problems for the organ builder who often also must deal with poor acoustics. Not all mechanical chests have been of outstanding quality throughout the decades. Why do they appear to be the one and only solution? There are many ways to get to Rome, also many detours probably.
In Budapest, they definitely found the right path! And, stranger, if you go and visit this great instrument and get the chance to play, try the main console. Even if your footwork cannot seen by the audience, it is worth it!

Rieger-Orgelbau GmbH, Schwarzach, Austria

Bryn Mawr
Presbyterian Church, Bryn Mawr, Pennsylvania

It rarely happens that a 30-year old organ is taken down and replaced by a
new one. It is even more startling when the organ taken down was a landmark in
organ building during the Orgelbewegung movement, with 68 stops, 98 ranks on
four manuals. At least for us it was the first time that we did so, in 2004 in
Bryn Mawr Presbyterian Church, Bryn Mawr, Pennsylvania. For Christoph
Glatter-Götz, president of Rieger from 1977 to 2003, this organ marks the
beginning and the end of his career with Rieger: in 1975, as his first project
with Rieger, he took part in the voicing process. The contract for the new
organ was the last for him to sign before handing over the company to his
former head of operations, Wendelin Eberle.

There were several reasons for the decision to replace this organ. The first
one was musical: the high standard of church music at Bryn Mawr Presbyterian
Church demanded an organ of the same versatility and wide range of musical
possibilities. The church was especially interested in having an organ that
would inspire and support the singing of its congregation and renowned choir.

The second was the acoustics of the church: porous Guastovino tiles on the
walls, a sound-absorbing ceiling and cork floors resulted in a reverberation
time close to zero. The old organ was scaled and voiced to fit this
environment. Over the years, several attempts to improve the acoustics resulted
in an acoustical environment, which, while improving the higher frequency
response in the room, proved inhospitable to the organ.

Finally, there was the mechanical aspect: this organ was one of the first
very large instruments with a detached, mechanical console. In addition, there
were too many stops in too small a case, which made maintenance very difficult.

With the decision to replace the old organ, the church decided to address
the deficiencies in the acoustic and to provide climate control so that the new
organ would live in a hospitable environment. The church's bold decision to
replace the old organ and to totally renovate the sanctuary has born much
fruit. The new organ truly sings in this grand old Gothic space.

The conditions proved to be ideal in many more ways, too. A collaboration
between organists Jeffrey Brillhart and Olivier Latry, organ builder Lynn
Dobson and Rieger-Orgelbau was extremely fruitful and led to a concept of an
organ with 59 stops (83 ranks) on three manuals and pedal.

Tonally the organ is inspired by the greatest examples of French symphonic
organ building. The first test of the French symphonic organ is that of the
fonds d'orgue. This organ's four 16-foot manual flue stops and twelve 8-foot
flue stops excel in creating a sound that is both noble and filled with
gravity. Frenchman Michel Garnier, one of Rieger's three voicers, achieved a
fonds d'orgue that is startling in its array of tonal effects.

Each manual has a complete set of reed choruses, ranging from a full-length
32-foot Bombarde in the pedal to a 16-foot Corno di Bassetto in the Positif
expressif. Two mounted Cornets, numerous mutations, and Mixtures in both the
classic and romantic style, combine to create a full organ that is powerful
without being bombastic, and at all times musical.

Visually, Rieger took its cues from the church's soaring Gothic space, which
hints at the grandeur of the French Gothic churches housing the masterpieces of
Aristide Cavaillé-Coll. This casework, all made in solid oak, contains
4,000 hours of labor; one man alone worked an entire year to carve all the
ornaments.

In technical terms this is an instrument with slider chests and tracker
action. The couplers are mechanical, too, but can be played electrically as
well. At the same time there are electric couplers 16¢ and 4¢ for
every manual. Including this second electric action makes possible the addition
of MIDI, pedal divide, and sostenutos. The combination system offers space for
1,000 combinations plus three inserts each, for 16 users. Theoretically, this
is a total of 64,000 combinations.

All through these 30 years, Rieger Orgelbau and Bryn Mawr Presbyterian
Church have enjoyed a warm relationship. We are delighted to continue this
relationship and we are grateful for the opportunity this project offers and
the commitment and open mind of all involved.

I also want to thank all the workers at Rieger, who built this organ with
great enthusiasm and pride.

May this organ lift up everybody's heart and praise the Lord with a joyful
noise!

Kegg Pipe Organ Builders, Hartville, Ohio

The Sharkey-Corrigan Organ, Texas A&M International University, Laredo, Texas

From the President of the University

Like a birth in the family, a new organ fills the community with expectation, optimism, and joy. Our experience of imagining an organ for Laredo very much mirrored a family’s strategy for acquiring progeny: plan and hope. In August 2003, at Texas A&M International University we opened and dedicated to the people of South Texas our new fine and performing arts center. Conceived to offer the best possible venues for music, dance, and drama, the university planners insisted upon including both a recital hall and a theater. From the very first discussions, the recital hall was to have generously live acoustics to ensure that music played in that room, regardless of dynamic, envelop both player and listener in that three-dimensional experience we all cherish in great halls. A large expanse behind and above the stage in the recital hall, conspicuously vacant at the completion of the building, was simply marked “organ” on the architect’s rendering.
A few days after the gala opening of the new center, E. H. Corrigan, native Laredoan and longtime patron of the arts in Santa Fe, New York, Washington, San Antonio, and Laredo, called and asked that we talk about how to fill that space. Mr. Corrigan’s generous determination to bring to Laredo and South Texas a world-class instrument led first to a national call for proposals, then a contract with Kegg Pipe Organ Builders to build the instrument.

Our vaunted expectations for the organ, both our needs and our wants, established clear indications for design. Since the organ is to inspire and undergird an academic program, we asked that it accommodate repertoire of all periods. Placement in a concert hall would allow for an intimate relationship between the organ and programs of great diversity—choral, band, orchestral. The instrument must be adequate to support a full range orchestral repertoire. While a tracker would be ideal for organ recitals, we asked for the flexibility of a movable console on the stage below the pipes. A plethora of reeds and solo stops, a solo division under expression, and a full positiv division in the forward position rück style provide a variety normally only found on a much larger instrument.
Today, like a family grateful for a trouble-free birth, we recognize that this project was from the first somehow marvelously blessed to be in the hands of Kegg Pipe Organ Builders. “I will be in Laredo on April 24, 2006. The organ will be done by late June,” Charles Kegg promised the anxious organ committee in the fall of 2003. And it was. Voicing is rich and full, a strategy to exploit the marvelous acoustics in the hall. Visually, the organ is nothing short of spectacular, the first instrument of its kind built in South Texas and on the Texas-Mexico border.

The dedication recital, by Dr. David Heller of Trinity University, San Antonio, did, in Dr. Heller’s words, “put the organ through its paces.” A capacity crowd listened attentively and roared to its feet on the last note of Craig Phillips’ Fantasy Toccata. In addition to numerous solo recitals and concerts with the Laredo Philharmonic Orchestra for this year, we are at present planning an organ symposium for the summer of 2007; the topic: “The Concert Organ: Its Music and Its Performers.”

From the Consultant and Artist

Selecting a builder for a new organ in a new concert hall is a rare opportunity for any consultant—and it poses a different set of questions with regard to its tonal design. At the onset of the project, the following criteria were established for the new organ: 1) It should have the ability to perform a wide range of the solo repertoire for organ; 2) It should work effectively with an orchestra, both as soloist and as a member of the ensemble; 3) It should possess the capability for effective collaborative performances with soloists and vocal and instrumental ensembles; and 4) It should serve effectively as a teaching instrument.

Recognizing that this new installation was for a concert hall and not a church, the desire was expressed for a flexibility that would allow for the performance of non-traditional literature, such as transcriptions and literature from the “concert hall” era of the pipe organ in the earlier 20th century. After careful study and analysis of the proposals submitted, TAMIU awarded the contract to Kegg Pipe Organ Builders of Ohio because of the firm’s innovative tonal design, the manner in which the proposal met our criteria, and the potential impact that such an instrument would have on the public. The end result has surpassed our expectations!

Each division of the Sharkey-Corrigan organ has a highly distinctive character. The Great Principal chorus is an evenly-voiced plenum based on 16' pitch and crowned by the Sharp Mixture III. This main body of the division is enhanced with a full complement of 8' registers (in the manner of 19th-century French organ building) and completed with a reed chorus that blends richly into the ensemble. One of the most beautifully voiced stops in the organ is the Harmonic Flute 8', which soars in the upper octaves, making it one of the most effective solo stops in the entire organ.

The Positiv division, cantilevered out in front of the main case of the organ, is a perfect foil to the Great division with its Principal chorus based on 8' pitch (and of a different tonal character from the Great). Completing the Positiv are two marvelous Baroque style reeds—the Holz Regal 16' (with a darker character, perfect for running bass lines), and a brighter Krummhorn.

The Swell division has a complete array of tonal resources for both the solo literature as well as the accompaniment of vocal and instrumental ensembles, capped off by a powerful reed chorus at 16'-8'-4' pitches. Of special note here is the Vox Humana 8'that makes the performance of Franck’s organ works an absolute joy for both the performer as well as the listener.

The Solo division gives this new organ its truly distinctive character with its combination of solo and ensemble registers. The Diapason 8' is especially effective when all of the divisions are coupled together, by reinforcing that particular pitch line. The Tromba chorus at 16'-8'-4' works extremely well in a full-organ registration much like the Bombarde division of a 19th-century French organ. The dark and haunting Clarinet along with the piquant English Horn provide the performer with greater opportunities for solo voices, particularly in transcription literature. One of the unique features of this instrument is the Solo Tuba, which is housed in its own expression box, making it useful not only as a solo stop but as an ensemble register as well, particularly in building up a crescendo to imitate the brass section of an orchestra.

And finally, the Pedal division provides effective support for the entire instrument, featuring an independent Principal chorus, softer flue stops, string stops to support the orchestral strings of the Solo division, and a full reed chorus based on 32' pitch. Judicious duplexing of manual stops to the pedal provides even greater tonal flexibility for the performer.

As an artist, I can honestly state that this organ is one of the most flexible and musically satisfying instruments I have ever played. Each stop carries its weight, and each stop does what the drawknob tells you. The balance between the divisions is so finely honed that one can select registrations with complete ease. It was a joy to conceive and put together an inaugural recital that combined the works of Hancock, Bach, Franck, Duruflé, and Phillips with more non-traditional repertoire by Lefébure-Wely, Ramón Noble, and Edward Elgar. And if all of that were not enough, the design of the console and the operating system for the combination action (one of the most user-friendly systems I have seen to date) made the entire experience of recital preparation and performance a breeze.

Texas A&M International University and the city of Laredo have a musical instrument in which they can take great pride. It will serve them well in the years to come and help cultivate future generations of organists and organ aficionados.

From the Builder

The new Texas A&M International University organ was at once a formidable challenge and a golden opportunity. The challenges were many: to build into a reasonable size instrument a tonal design that could play with conviction organ literature of all styles, accompany great choral works, and also crown the resident Laredo Philharmonic Orchestra in romantic splendor. Dr. Ray Keck, university president, organist, project lightning rod, and Bach aficionado, also made known his desire for accurate renderings of Bach. All this was to be done with an instrument that is not exceptionally large and with some significant space limitations. We are delighted to have been chosen for this landmark instrument.
Our tonal design was based on the simple fact that this was to be the only instrument on campus (indeed the only concert-size organ in a large geographical area), and needed to be used for teaching, practice, recital, and with orchestra. It needed to have a full spectrum of dynamic range from very delicate to confronting a full orchestra—and win. For practice and teaching, the majority of voices needed to speak at comfortable volume levels that would focus on color and deliberately counteract aural fatigue.

In addressing these needs, we started with four independent Principal choruses, each with its own character and purpose that provide proper polyphonic clarity. The articulation is not pronounced, but precise speech is always apparent. The Great chorus is full and noble. The Positiv is light and delightful, equal in impact to the Great. The Swell is richer than the Great with its slotted 8' and deeply textured Plein Jeu. The glory of these choruses is that Bach, Buxtehude and Bruhns are sheer delight, and it is not until six or seven preludes and fugues later that the organist realizes that not even a single unison coupler has been touched! When the couplers are engaged, the new organ at TAMIU begins a remarkable transformation. The same stops that gave such clear distinction to divisions in the Baroque literature now become contributors to a more global full organ sound. Beginning with the softest Flauto Dolce it is possible to build a seamless crescendo to full organ that is an intricate fabric of sound, at once cohesive and fabulously rich in texture and color.

Each stop in the organ does exactly what one would expect and need it to do, but there are several specific tonal features that will enjoy further exploration here. The Great has two reed choruses. The Trompetes are light and are intended for early works where the chorus reeds are subordinate to the flues. The Tromba chorus is intended for those works where the reeds must command the respect of the principals and dominate them. For those in-between works, the Tromba chorus is located in the Solo box such that they can be reined in as required.
There are three Cornets in the organ. The Great has a Principal Cornet that is commanding. Built décomposé, it can be tailored. The Positiv Cornet is of lighter principal character and has a flatted seventh added to the normal third and fifth, giving the stop a lovely edge that is very distinct. The Swell Cornet is of flutes and is serenely gentle.

The Solo Diapason IV 8¢ is a collection of unenclosed principal stops from the Great and Pedal, all playing at 8' pitch. This quartet of 8' principals gives the organ a velvet Diapason line. The stops are drawn from the Great Principal, Great Octave, Pedal Octave and Pedal Choralbass.

The Tuba is located in the very heart of the organ case, in its own swell box. On 18" wind, this stop can solo above the full ensemble or with shade control can be subtly brought into the full ensemble, blending easily with it and expanding it horizontally.

The case design here presented a particular challenge. The TAMIU organ is located in a low balcony above the hall stage. There is not a lot of height to allow the organ to visually soar. The solution was to build a Rückpositiv that is lowered into the back stage wall. This has the visual effect of anchoring the organ to the stage in addition to providing the classical forward position for the division. The main case is considerably wider than it is high. Organ cases are happiest when their proportions are as pipes: tall and slender. This was not possible here, and much care was taken to give the case as much verticality as possible. The lowered Positiv case helps with this. The center three towers of the main case stand forward of the side Pedal towers. The change of depth is accomplished as the outside pipe flats curve. The result is very satisfying in the room.

I approach every organ in a comprehensive manner. Placement of divisions within the room and in relation to each other is as important as scaling and voicing. The case design is a classic five tower design plus Positiv with a contemporary flair. The gilded pipe shades are a stylized interpretation of the university seal, which includes a globe showing the Western hemisphere. The internal layout has the Great high and in the center. The Swell is behind it. The Pedal upper work is below the Great. The Positiv is below and forward of the Great. Thus the main manual divisions are centered in the hall with their physical relationship matching their musical relationship. This enhances polyphonic music when the organ is played uncoupled and blends the divisions together when the divisions are combined. The Solo division is in the right side of the case and the Pedal basses are in the left side. For those that are interested in unusual pipe design, the 32' Trombone is large scale and is built with Haskell bass pipes, which are not common when used with reeds. They save considerable lateral space over mitering when height is severely restricted.

Working with the TAMIU staff could not have been easier or more delightful. We are indebted to Dr. Ray Keck, university president, who envisioned the instrument from the start and drove the project; Dr. David Heller, consultant and artist of the opening concert, for his thoughtful help and encouragement; physical plant manager Richard Gentry for his instant and complete help during installation; and of course to E. H. Corrigan for his generous funding of the entire project. The organ bears the name of Sharkey-Corrigan in memory of Mr. Corrigan’s mother.

My personal thanks also to the Kegg staff including Fred Bahr, Phil Brown, Joyce Harper, Mike Carden, Phil Laakso, Walt Schwabe, Rick Schwabe, and Tom McKnight. In addition to these people being the finest craftspeople I know, they are also the finest friends.

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.
