From the builder

The Welte name is mostly known for its roll-player mechanisms, the Mignon reproducing piano, and their Orchestrion. However, as builders of traditional pipe organs, Welte’s output was small; organs were but one in a family of Welte “products” typical of the era’s massive instrumental output. In 1912, Welte opened a factory in Poughkeepsie, New York, but their earliest organs were purchased from other builders and fitted with Welte players. Since Welte was of German ownership, the First World War threw things into disarray, and after the war, ownership changed hands. A larger reorganization in 1925 by former Kimball man Robert Pier Elliot had Welte building its own organs of fine quality and for any venue: residence, theater, or church. But the firm struggled to gain a strong financial footing. It suffered a setback in 1927, repurchase and relocation in 1929, and finally absorption by Kimball of Chicago in 1931. Today, there are few surviving examples of Welte organs, and, even after our 42 years in business, we had never worked on one. St. Mark’s Minneapolis would be a new experience. 

The cathedral’s consultant was David Engen of Maple Grove, Minnesota. His request for proposal offered a general description of the organ’s overall condition. Our assumption was that we would see huge diapasons, pencil-scale strings, and tibia-like flutes, all on a massive chassis. In fact, the St. Mark’s Welte had been tonally and mechanically modified on two different occasions by M.P. Möller. Much of the Welte material was long gone, although the organ remained capable of producing an impressive volume of sound.

But it was clear the various rebuilds had compromised the instrument. The chamber was packed with non-Welte chests, flexible wind lines, dangling wires, and a chamber entrance door that barely opened, due to added ranks and equipment. There were reservoirs everywhere, fully 17 in the main organ. Tuning access was bad enough, while actual service work required unnecessarily heroic effort. One reason the organ continued to generate an impressive sound was the chamber’s placement and hard walls. More than projecting sound, the chamber almost seemed to amplify it. The cathedral’s impressive acoustics certainly helped as well. 

The organ was on its third console and had a dated relay system spread throughout four different areas of the building. In the basement, the large Spencer blower’s motor needed all new bearings. Adding insult to injury, HVAC ducts installed in the 1950s had seen the removal of the organ’s important static reservoirs, further compromising the wind supply.

At Foley-Baker, we love to save old organs. However, it was clear that at St. Mark’s, there wasn’t an old organ to save, just parts of one. Trying to determine what was possible and affordable would take both positive and practical thinking. If the organ were to be rebuilt, the results had to be worth the investment. 

We spent days measuring pipe scales and gathering details. There were interesting finds, such as high in the tower, where the Möller crew had stored some of the 1928 Welte pipework. There was much damage; some ranks were incomplete, while others were beyond repair. Our tonal director Milovan Popovic laid out rank after twisted rank on the large tower room floor. Out of this survey we found three Welte stops to reclaim: the Swell 4′ Clarion, Great 8′ Second Open Diapason, and the large-scale Swell 8′ Vox Humana. All three became valuable additions. 

As our familiarity with the cathedral’s music program and organ grew, so did our concepts for the renewed instrument. Tonally, we had 1920s Welte mixed with 1980s Möller. In 2012 it is perhaps too easy to criticize Möller’s radical changes as heavy-handed; they were in the spirit of the time, and had introduced a variety of useful colors, including mutations, large-scale strings, and solo reeds. In time, we decided just where and what reused ranks would work and what new ones had to be added to create a bold, cohesive American sound to fill the cathedral’s large nave.

The chamber size and shape dictated the same stacked layout as had existed from the beginning. For us, multi-level organs raise red flags for service accessibility. Without careful design, the new and larger instrument had the potential for being another service nightmare. Our solution was to start from scratch, using a new chassis designed and built at Organ Supply Industries. The elegant simplicity of their slider chests promised minimal maintenance and assurance of accessibility. Their built-in schwimmer-regulators greatly simplified the winding, adding space for more stops and wider passage boards.

Given the scales and pressures, effective swell boxes would be essential. The original Welte shades were rebuilt and fitted to new boxes of 11⁄2-inch-thick medium density fiberboard. The combination of the two makes for a marvelous range of expression; massive ensembles can whisper or roar.

In addition to restoring the 1928 Spencer blower, we were able to find and install appropriate static reservoirs. Unlike 1928, however, this equipment now stands in separate rooms dedicated for the purpose. The result is that, despite wind pressures from five to 20 inches, an indicator light is necessary to know that the wind is on. As we have done elsewhere, we designed and installed an automatic, in-chassis humidity system that requires minimal service attention and combats Minnesota’s problematic humidity swings. 

The low-profile Schantz console dating from 1990 was reused, with modified stop jambs, new drawknobs, and burled mahogany jamb faces for a sharper appearance. (Schantz graciously provided and installed new, easy-to-read piston buttons.) We installed a new electronic relay that is easily accessed by simply raising the now-hinged console lid.

Years of change had seen many stops swapped between divisions. The Choir Diapason had been moved into the Solo as a 4′ Octave. We returned it to the Choir at 8′ with a new bass octave. The Welte Second Open found in the tower became our Great Diapason. Other stops were also returned to their original 1928 locations. The renewed instrument is a blend of remaining Welte pipework, selected Möller ranks, and important new registers. All retained ranks were cleaned, repaired, and revoiced, perhaps none more important than original large pedal basses and their Welte chests. These provided the weight and heft we envisioned as a foundation for the new instrument. 

The reed stops presented their own challenge, with ranks by five different builders and, in some cases, using scales and pressures dictated by available—or unavailable—space. Working with Chris Broome of Broome & Co. LLC, we examined the potential of each rank for our new scheme. In the end, we designed and had built an all-new Great reed chorus. Having found the original 1928 Welte 4′ Clarion, we were able to use it to recreate Welte’s original Swell reed chorus; industrial strength pipes with a just-right massive sound. A small-scale yet piercingly loud Möller Trumpet, which had been taking up valuable room in a corner of the Great, was revoiced into an ideally scaled Choir Trompette. Chorus reeds now serve to cap wonderful choruses, enriched by solo stops such as the Skinner Clarinet or Kimball Corno d’amour. 

The new organ’s sound ties together all the good qualities that go into creating it: the new specification, high pressures and large scales, the chamber’s ability to project sound and the swell shutters’ ability to contain it, and the new layout and chassis, which provided optimal placement for all stops. As the bottom photo on the front cover clearly displays, even 1928 pipes can look (and sound) like new. We were really thrilled to hear Canon Musician Ray Johnston play the “new” organ at the inaugural concert on May 18, an outstanding program that included brass and the cathedral’s choirs. To him and David Engen we owe thanks for supporting us in this challenging and rewarding project.

Upcoming concerts involving the rebuilt organ are posted on the cathedral’s website. All photos of the cathedral and reconditioned instrument are by Mark Manring (www.manring.net). All other photos are from Foley-Baker, Inc. files.

From the canon musician

St. Mark’s Cathedral has long been known for its various music programs and concerts. Built as a parish church in 1910 and designated a cathedral in 1941, it has during that time seen six directors of music as well as a number of rebuilds and additions to the original four-manual Welte installed in 1928. As musical tastes changed throughout the century, the tonal plan of the organ became distorted, becoming a combination of classical and romantic sounds, leading to a loss of identity for the instrument. 

The various additions also led to a chronic lack of space within the organ chamber, preventing access for tuning and repair to pipes bending over with metal fatigue. Equally worrying was the damage done to the winding as abundant leaks had resulted in pressure drops throughout the organ. 

In 2010 the cathedral launched a capital campaign, included in which was repair to the organ’s winding. However, on closer inspection it soon became apparent that problems ran very deep and fixing the leaks would in fact be a waste of money. Major action was required. The choice was stark—total reconditioning or a new instrument. This was an easy decision: much of the original Welte chorus was in good condition and had such quality and character that it could become the basis of a major overhaul. 

Next came the biggest challenge—persuading the vestry and the congregation that a lot of money needed to be spent to keep the organ in working order. To many, of course, the organ sounded just fine, as it always had. As is often the case, organists’ abilities to mask faults and ciphers go unnoticed by the majority. However, thanks to many organ tours and presentations by both committee and builder, and the fact that music and the pipe organ are such an integral part of worship at the cathedral, we were able to reach our target of $1.2 million.

In consultation with our selected firm, Foley-Baker Inc., a new specification was drawn up that necessitated replacing one-third of the pipework and relocating ranks from the gallery to the main organ. Of primary concern was an instrument to accompany the liturgy, from providing subtlety and color for the cathedral choir’s large repertoire to giving stimulating leadership to congregational hymnody. If the organ could do both those things well it would surely prove to be an admirable recital instrument also. 

While not a particularly large four-manual instrument, at least by American standards, it has exceeded all expectations as a concert instrument: almost endless color, a vast dynamic range, and a character that is totally suited to the building, all exquisitely voiced. It is unashamedly in the English romantic style, and, having played many of the great cathedral organs in the U.K., I am delighted that we now have such a fine instrument in that tradition, as well as an organ that is true to its original intention.

From the committee chair

In May 2012, the refurbished St. Mark’s organ was inaugurated for concert audience and worshipers. Those were thrilling experiences, the result of meticulous planning and craftsmanship by Canon Musician Raymond Johnston and Foley-Baker, Inc.

I was privileged to chair the organ planning committee during the last phase of its pre-construction work. This was undertaken in the context of St. Mark’s “Opening Our Doors” capital campaign, which, by any standard, was a clear success, raising over $3 million. I was also privileged to co-chair the capital campaign with Inez Bergquist, Doug Eichten, and Courtney Ward-Reichard. The capital campaign had three highly visible purposes: restore the exterior of the 100-year-old building to stop leaks and deterioration; improve a long list of interior infrastructure items; and repair/restore the pipe organ. The first two of those purposes were easy for members and contributors to see and understand, especially when ice formed inside the church and fell on folks in procession during Sunday worship. The organ was a different matter.

Even though much of the organ was well beyond maintenance and some of it dead or ciphering, it still sounded pretty good much of the time. Most of this was attributable to Ray Johnston’s talents and the marvelous acoustic characteristics of the St. Mark’s Cathedral space. We conducted behind-the-walls tours of the chambers to show potential donors the points of failure and the grossly antiquated control mechanisms, leaking air handlers, and failing wiring. We were also careful to explain that much of the tuned pipework and blower could be restored and would be maintained.  At the end of the many days, the congregation did contribute and one very generous, anonymous donor provided most of the funds needed for the more than $1 million organ project.

While Foley-Baker did their work, the entire instrument was removed and a digital organ was rented and used with speakers around the cathedral. Many regular attendees commented that they could “hear the difference” and had come to understand why it was appropriate to rebuild a fine pipe organ. That was brought home once again to me on Sunday last, when Ray Johnston offered Samuel Sebastian Wesley’s Choral Song and Fugue as the service postlude. Most of the congregation stayed to hear it and to celebrate the glory of the rebuilt organ.

Color my world

Twenty years ago I was serving a New England Congregational church as music director, bringing the glories of the English cathedrals to the land of the Puritans. It was a dirty job, but someone had to do it. The moderator of the parish council was a curmudgeonly attorney who lived in an attractive house sited prominently on a corner lot along my route to the church. The Sunday after contractors finished painting his house, I teased that he had his house painted pink. He responded in his usual gruff way, “It’s Chippendale Rose.” Ha! My point. It was pink.

When placing organs in church buildings, we often leaf through the “swatch fans” provided by paint companies, and I always wonder who invents the names of paint colors. The website of the paint company Pratt & Lambert shows a cozy-looking room featuring the colors Pearl Tint, Toasted Wheat, Dusk Sky, and Gloaming. The P&L color experts deem this to be a winning combination. The first three names give clues as what the colors might be, but “gloaming?” What’s gloaming? Its root, glo-m, is an Old English word of Germanic origin that means “twilight,” and is related to “glow.” So gloaming refers to the glow of twilight. I would describe the color in the photo as a sort of dark ecru—“twilight” and “glow” mean something else to me than dark ecru.

The printer on my desk spoke to me the other day. A cute little chime rang and the screen informed me that I needed to replace the cyan cartridge. Cyan? It’s a sort of light blue. My printer has three color cartridges: cyan, magenta, and yellow. I think of primary colors as red, yellow, and blue, so I googled to learn that there are now at least three basic systems of blending colors, each based on three “primary” colors.  

The standard for photography, television, and video screens is an “additive” system that uses red, green, and blue. The standard for printing is a “subtractive” system that uses cyan, magenta, and yellow. (Combine those three colors and you get black.) The website I visited says artists still prefer the additive system that uses red, yellow, and blue.¹ That’s a relief! Seems to me that the world of art would be a different place if Rubens, Rembrandt, Monet, and Picasso had cyan, magenta, and yellow on their palettes as primary colors.

 

Colors in music

I’m a devoted fan of Captain John Aubrey, the principal character in Patrick O’Brian’s series of novels about the British Navy during the Napoleonic Wars. In the first scene of the first novel, Jack meets Stephen Maturin (a physician, drug addict, and elite member of Naval Intelligence) at a concert by a string quartet. They are as different as two men can be, but after their introductory dispute they become firm and fast friends, and they share a love for music. Jack plays the violin (his “on land” violin is a Guarneri), Stephen plays the cello, and through the twenty-year span of the war, they spend thousands of evenings playing together in the captain’s cabin while enjoying their customary toasted cheese and Marsala.

In the second novel, Jack is promoted from the rank of Master and Commander (remember the Russell Crowe movie?) to Post Captain. That night, in his happiness, he dreamed about a painting owned by his old nanny, now wife of the First Lord of the Admiralty, the man who had promoted him: 

 

Some exquisite dreams: the Magdalene in Queenie’s picture saying, “Why do not you tune your fiddle to orange-tawny, yellow, green, and this blue, instead of those old common notes?” It was so obvious: he and Stephen set to their tuning, the cello brown and full crimson, and they dashed away in colour alone—such colour!²

 

When I first read that passage I immediately compared it to playing the organ. We accept the traditional system of notes, harmonies, and tuning as common with all other instruments, but the organ is unique because of its range of color. A pianist or flautist can conjure up contrasting tone colors by varying the physical forces involved in playing their instruments, but if you sit at an organ console and compare a Cromorne to a Diapason, a Trombone to a Rohrflute, or an Open Wood to a Tierce, you realize that the organ is a collection of instruments that contrast and complement each other, and like the painter’s palette of colors, the organ’s drawknobs allow the musician to blend a finite number of basic timbres into a seemingly infinite number of color combinations.  

 

Express yourself in color

I’ve heard that some symphony conductors consider the organ to be the least expressive musical instrument because the basic unit of musical tone—one organ pipe playing one note—cannot be altered in volume or timbre. That fact is true enough, but it’s like saying yellow is a boring color because all it can do is be yellow. Pratt & Lambert shows me Old Linen, Buttery, Golden Glimmer, Bay Rum, and Colorado Sand as complementary shades of yellow, and I haven’t touched the blues, reds, or greens. It’s ridiculous and ignorant to say that a pipe organ is not expressive.

Let’s consider an eight-foot flute stop, a simple enough subset of organ tone. But is it a Flauto Dolce, Gedeckt, Melodia, Harmonic Flute, Rohrflute, Spitzflute, Koppelflute, Hohlflute, or Flûte Triangulaire? Nine different flute stops, each with a unique tone color, and each comprising pipes of different shape and construction. Could you discern between them in a hearing test? Could you name each one if shown photographs of the various pipes? Or do you just draw an eight-foot flute because you always use an eight-foot flute in this piece as if you were painting a wall yellow instead of Golden Glimmer?

Pratt & Lambert says:

 

The color of the sun, yellow is associated with laughter, happiness and good times. It can cause the brain to release more serotonin, which makes people feel optimistic. It even has the power to speedup [sic} metabolism and drive creativity. However, yellow can be overpowering if it’s not used sparingly in just the right places. Use it to add zest to a cool palette of blues or grays. It can also work well with orange, red, olive green or brown.³

It would be easy to paraphrase this when discussing organ stops:

 

A Cornet can be overpowering if it’s not used sparingly in just the right places. Use it to add zest to an Oboe, Cromorne, or Trompette. It can also work well with Principals at eight and four-foot.

 

Is your imagination strong enough to find ways to use that Cornet that will make people feel optimistic?

 

Clashing or harmony?

You and your partner are getting dressed for a party. She comes out of the bathroom, takes one look, and says, “You’re not wearing that, are you?” We all think we know when colors clash, but while there are some basic rules, you have to judge each comparison separately. Otherwise, it would be impossible for two shades of red to clash. I have a pairing of red shirt and red tie that I think looks great, but there are also a couple doozies of possible combinations of red hanging in my closet that Wendy would question, rightly.

When we register a piece of music on a particular organ, we have to judge each combination separately. It’s not safe to assume that because it sounded good on one organ, that it will also sound good on another.

In his wonderfully researched book, The Language of the Classical French Organ (Yale University Press, 1969), Fenner Douglass presents detailed information about the various “standard” registrations in seventeenth- and eighteenth-century French organ music. He opens Chapter 5 (Registration in the Classical Period) by citing the prefaces to various famous “books” of organ music, the Livres d’orgue of Corrette, Nivers, Lebègue, Boyvin, and many others. He boils all that data down into charts that compare the registrations for Le Grand Jeu, Fugue, Le Duo, etc. by all these composers. It’s terrific material for informing our playing today, but does it have any real meaning if we don’t hear those registrations on the specific organs? One chart shows that in 1676, Nicolas Lebègue uses Grand Jeu de Tierce for the left hand of Le Duo, while Dom Bedos suggests sixteen-foot foundations. Who is right? And what organs were they using?

Assuming the Möller organ in your church has all the correct names and pitches on the knobs as cited by Fenner Douglass, does the historically correctly drawn Grand Plein Jeu sound anything like what Lebègue was hearing? Simply and definitively, no. Douglass has given us a great gift by collecting this information, but you still need to use your ears.

 

Shutter bugs

Besides choices of colors, many modern organs have an additional dimension of expression. Enclosing a group of stops, usually all the stops of one keyboard, in a tightly and heavily constructed “box” with movable shutters on one or more of the faces, allows the organist to simulate control over the volume of a single organ pipe. This does not literally answer the conductor’s ignorant criticism because the pipe is still only speaking one pitch at one timbre at one volume level.
But it increases the organist’s palette of
colors exponentially.

When I was a teenager, a mentor listening to my preparations for a recital commented that if everyone used the Swell Pedal like I was, they’d have called it a crush. I was closing the box at the end of a phrase, and popping it open before starting the next phrase, using only half of the device’s possibilities—but I was still too green to realize that the expression is about more than volume. It’s also an important tool for the creation and manipulation of tone color.  

When two or more manuals are coupled together, moving the expression pedals changes the emphasis from one tone color to another, taking the organ’s color spectrum from the finite number of possible combinations of stops to the infinite. Here’s a simple example. You might play the opening verse of a hymn on Great Principals with a Swell Trumpet coupled in, saving the more powerful Great Trumpet for later. Add to that registration the dimension of starting the verse with the Swell Box closed, and open it gradually as the choir comes down the aisle. The sound of the Trumpet is subtle at first, and blooms into being the principal ingredient of the aggregate color.  

Think of an “Old Master” painting. When Meindert Hobbema takes your eyes from the green of a tree canopy to the blue of the sky, he takes you through an infinite spectrum of colors. Compare that to the results of a color-by-number kit in which the boundary between one color and another is defined by a stark black line. And think of the artist making a drawing with charcoal or pastel, using her fingers to smudge the lines to create shading. Smudge is no better a description for the use of the expression pedals than crush, but the creative colorist at the organ can use the expression pedals to enhance the transitions from one color to another. That’s painting with sound, like Captain Aubrey’s colorful violin strings.

 

Stop, look, and listen

In these pages, I’ve often mentioned formulaic organ registration. You play the opening of a baroque Prelude and Fugue on Organo Pleno—Principals eight, four, and two, plus Mixture. You’ve always done it that way. Fair enough. That implies that the opening of Bach’s B-Minor Prelude (a high and screechy B) should be registered the same as his Dorian Toccata (middle of the keyboard canonic counterpoint). We are free to choose registrations that reflect the response of the specific instrument playing the specific notes in the specific acoustic. 

I think of my own performances of Bach’s B-Minor, how in the boop-da-da-da-da-da, boop-boop-da-da-da-da-da, boop-boop episode of the fugue I always reduced the registration to flutes at eight and two. Always.

As I think about the opening of that great piece, I wince at the high B. What about starting on a smaller registration (that hymn registration I described earlier?) so the opening high B is less jarring. And here’s a radical thought. I know organs that simply don’t have stops that can be combined to give an impressive and dignified sound on that high B, so maybe I won’t play that piece on one of those organs—the ultimate registration discretion. There are other pieces.

Have you ever heard an organist play the opening pedal solo of Buxtehude’s Prelude, Fugue, and Chaconne on anything other than pretty-much full organ, including reeds and mixtures, and manuals coupled to the pedals? Me neither. Why doesn’t someone play it on a four-foot flute? One of my favorite organ tones is a good clear Koppelflute, especially in a spacious acoustic. Would the Buxtehude cops storm into the church if I played that opening pedal solo on a four-foot Koppelflute? Would the first-time listener be disappointed?

If you, as an educated and experienced organist, went to an organ recital and the performer had the nerve to do that, would you be offended or disappointed? Are you just as happy to hear the same piece played with the same registration by every organist on every organ? Or are you excited when someone offers a fresh approach to an old warhorse? If we’re not listening as we register pieces, why should we expect the audience to listen?

Once when a colleague was demonstrating the organ in his church to me, he drew a huge combination of stops and told me that was his typical registration for postludes. Yikes. Easter I? Advent I? Pentecost XVIII? Bach? Widor? Stanley?

You go to a restaurant and order a chicken breast with lemon, butter, capers, and parsley. Delicious. Next week you go a different restaurant and order chicken breast with lemon, butter, capers, and parsley. And the next week, and the next. Different chef, different cooking temperature, different weather, but same ingredients. Can we think of a different way to cook a chicken breast?

How many different colors can you paint a front door and still be correct?

If we say Swell instead of crush, why do we call them stops? That seems limiting. Why don’t we start calling them Go’s? No matter how many of you agree with me, we’re probably stuck with stops. It would sound ridiculous for a politician to say, “We’re pulling out all the go’s.” But in your mind’s eye—and ear—think of them as opportunities, possibilities, or ingredients. If you’re listening when you draw stops, there aren’t many wrong answers. You’ll know if the tie clashes with the shirt. Have a blast. Put it on my tab. But hold the capers. They’re not my favorite.

Létourneau Pipe Organs worked closely with the cathedral’s architect, Craig Hartman of Skidmore, Owings & Merrill, to develop the organ’s visual design, through a process of discussion, collaboration, and at times, mutual compromise

 

Létourneau Pipe Organs, 

Saint-Hyacinthe, Quebec, Canada

Opus 118 (2010)

The Cathedral of Christ the Light, Oakland, California

 

From the director of music and 

organist

In July 2009 I was appointed director of music and organist for the Cathedral of Christ the Light, well after the cathedral was built and the organbuilder had been selected. Unlike similar organ projects, I could not take credit for the new instrument. However, even in the early stages of the design of the cathedral, the pipe organ formed an integral part of the building’s design. The cathedral’s architect, Craig Hartman, was extensively involved in the design of the pipe façades and the organ console, so that they complement the overall design of the cathedral.

At the time when it became clear that Oakland would be home to a great cathedral, Daniel Whalen and his wife, Katharine Conroy Whalen, thought of her mother, Gerry Conroy. The Whalens soon made the decision to give a custom-made pipe organ in her memory and, as such, all funding for the Conroy Memorial Organ came from the gift of Daniel and Katherine Conroy Whalen.

The organ committee did extensive research and visited several instruments by several different builders before the decision was made to commission an instrument from Létourneau. Because of the layout of the cathedral, it was apparent from the project’s inception that a tracker instrument was impossible and that electric action would be necessary. The organ needed to serve both as a liturgical instrument and as a concert instrument. It needed to be capable of accompanying choral repertoire and congregational singing, providing processional fanfares, and playing a variety of organ literature in both liturgical and concert settings.

The instrument has been a great success, serving the Diocese of Oakland and the cathedral parish well in liturgical settings, as well as making the cathedral a sought-after venue for organ and choir concerts.

—Dr. Rudy de Vos

 

From the builder

Létourneau pipe organs are custom-built for their surroundings, and we strive for a good fit, both architecturally and tonally. From time to time, we are privileged to work in some exceptional surroundings. We knew this to be the case from our first contact with the Cathedral of Christ the Light in the spring of 2006. Though the cathedral existed only as a design on paper at that time, the clarity of the worship space’s towering architecture was as striking as the use of sunlight filtering through the ceiling’s central oculus, and the hundreds of wooden louvers making up the sides of the worship space.

Also striking were the locations set aside for a pipe organ in the architectural plans. Large canopies on either side of the cathedral’s central omega window were designed to display a significant instrument, while a discreet organ chamber was provided behind the seating area for the cathedral choir. The lateral and vertical distances between these three locations presented a number of intriguing possibilities but also a number of challenges.

Having agreed to work closely with the cathedral’s architect, Craig Hartman of Skidmore, Owings & Merrill, we developed the organ’s visual design through a process of discussion, collaboration, and at times, mutual compromise. From the outset, Mr. Hartman wanted the organ’s visual aspect to leave an organic impression (no pun intended), with organ pipes arrayed unpredictably, as one might find with trees in a forest or tufts of wild grass. The great majority of the organ’s façade pipes were accordingly constructed from clear Douglas fir to match the surrounding ribs and louvers. Special narrow scales were developed to provide the wooden basses for the Great and Bombarde 16′ principal ranks, while the Pedal 32′-16′-8′ Contra Bourdon and 16′ Open Wood are more typical, with generous cross-sections. All wooden façade pipes were constructed with wooden skirts to conceal the pipe foot, providing a uniform appearance from top to bottom.

Likewise, the 32′-16′ Trombone and 16′ Bombarde stops were provided with full-length wooden resonators in the bass octaves and appear to sprout up through the organ façades. The number of tin pipes in the façades was carefully limited, while a unique finish was developed to ensure the metal did not appear overly brilliant relative to the surrounding surfaces.

Oakland’s previous cathedral, the Cathedral of St. Francis de Sales, was heavily damaged in the 1989 Loma Prieta earthquake and was eventually condemned. The new cathedral’s structure was consequently designed to absorb large seismic shocks; the entire building sits on isolator pads to resist oscillations in the event of an earthquake. The organ, too, was built to a rigorous standard for seismic reasons. The visible portions of the instrument are built around substantial steel frames, which are anchored to the platform of each canopy. The irregular arrangement of the façade pipes ruled out the usual linear pipe racking, and instead, most pipes are supported independently from behind by steel rods.

The main level of the cathedral has a substantial climate control system inconspicuously built into the nave floor. The system can heat or cool the ambient air to a height of approximately 15 feet above the floor. Being built into the reliquary wall, the organ chamber is likewise controlled for temperature. However, the immense volume of air above this 15-foot height has no climate control at all, and air temperatures can vary greatly depending on internal and external conditions. This is to say that temperatures on the two organ canopies would vary unpredictably from the organ chamber below but could also diverge between the two sides of the building.

Given the disastrous implications this would have on tuning, it was nonetheless with some reservations that we agreed that some form of climate control had to be provided for the organ canopies themselves. After many meetings and discussions, a system was put into place; it is comprehensive and self-regulating. Each organ canopy has its own microclimate control system capable of providing heat or cool air as required. A total of eight sensors per canopy monitor temperatures from strategic locations, and treated air is then directed as needed to twelve diffusers per side. From the outset, it was understood that the system could not provide absolute temperature stability, but would minimize temperature variations among the organ’s divisions as much as possible, ensuring the instrument is broadly useable.

The stoplist for the instrument evolved over the life of the project, based both on our own design and with input from the cathedral’s organ committee. We felt from the outset that the lower organ chamber needed to house an instrument that could function independently from the main organ when desired. The result was a 25-rank orgue de choeur (essentially the two Choir divisions) that was installed as the first phase of the project and was first heard at the cathedral’s rite of dedication on September 25, 2008.

The Choir, Echo Choir, and one 16′ pedal rank speak through a screened opening in the reliquary wall to the west of the central altar. The Choir division has the resources of a minor Great division, with complete principal and reed choruses, while the Echo Choir contrasts with more delicate colors. Essential for accompanying, both divisions are independently expressive, feature light 16′ manual stops, and offer distinct celeste effects. While not surprising, we have noted that the cathedral’s acoustic reacts in a decidedly muted manner to sound from the chambered divisions when compared to sound from the canopies above.

Befitting its visual dominance and the cathedral’s great interior volume, the main organ is grand in its scope. The Great division is particularly large and flexible, offering a 16′ principal chorus, a variety of foundation stops, and three mixture options, with the Cornet stop being made up of principal-scale pipes. The Swell is likewise colorful and is enhanced by its efficient enclosure; the 16′ Gamba pipes—open down to 16′ C—are mounted horizontally against the back wall of the division. The Solo division offers a number of specialized, even orchestral, stops that one reviewer praised as “retro Aeolian-Skinner voices.” The 8′ Doppel Flute makes for a powerful and harmonically rich solo voice, while the Viole d’orchestre and Viole céleste are razor-sharp in their tone. The Bombarde and Pedal divisions are inextricably intertwined, as the Bombarde stops are upward extensions of select pedal ranks to produce climactic choruses. The Bombarde division’s principal chorus is pleasingly dense, with the mixture adding weight and brilliance in equal measure. Other pedal ranks were deliberately not shared with the Bombarde division, to ensure the Pedal division could always have the last word; these include the 32′-16′-8′ Bourdon, the 16′ Open Wood, and the 32′-16′ Trombone ranks.

Reed choruses throughout the organ are intentionally varied; the Swell trumpets employ tapered English shallots to contrast against the French-inspired reeds in the Choir division. The Bombarde trumpets at 16′, 8′, and 4′ pitches are particularly grand in their effect, resulting from higher wind pressure, generous resonator scales, and Bertounèche-style shallots. The Solo 8′ Tuba, speaking on 18 inches of wind, uses closed Willis-style shallots and harmonic resonators from G20 up to achieve its particular pealing tone. In contrast, the 8′ Trompeta de luz is mounted horizontally in the organ’s façade and speaks on just over six inches wind pressure. The Trompeta de luz is not so powerful as to be harmful when brought in for the occasional final chord. The Pedal division’s 32′-16′ Trombone rank features our own Schnitger-type shallots for a firm, grounding bass tone.

The design of the unique four-manual console was also a rewarding collaborative effort with Craig Hartman. It was at his suggestion, for example, that the shapely upper portion was constructed using laminated strips of quarter-sawn oak. Our intention was to provide a uniquely uncluttered and timeless design; the final product has a total of 157 long-stem ebony drawknobs sweeping around the organist against a backdrop of rich walnut. Alert readers will note the console has three expression pedals, while there is a total of four expressive divisions. The default mode of operation has the Echo Choir following the Choir expression pedal, but it can be reassigned to any of the other pedals via drawknobs as well as programmed to change pedals on the General pistons. There is also an All Swells to Swell function for good measure. Other refinements include remote thumb pistons operating the General piston sequencer, to allow page-turners to assist with registration changes, and an All Pistons Next feature.

The opening concert was performed on February 11, 2010 by Parisian organist Olivier Latry. The program featured well-known works by Boëllmann, Bach, Barié, Vierne, Duruflé, Cochereau, Messiaen, and Widor. Marking the first time the instrument’s full resources were deployed, we noted that the capacity audience had a calming effect on the cathedral’s tremendous acoustic. This equally made our instrument sound with improved clarity and precision.

The morning after M. Latry’s concert, it was gratifying to receive a letter from Mr. Hartman with his reaction to the completed instrument: “The organ is just magnificent . . . I’ve been told the architecture sings, but, at last, it truly has a voice . . . The quality and precision that Létourneau’s craftsmen brought to this amazing instrument is everything I could have wished for and more . . . The entire ensemble—not only the pipe arrays but also the console—is truly an extension of the cathedral’s architecture.”

In closing, we would like to offer our thanks to the following individuals without whose help our Opus 118 would not be the success it is: Dr. Rudy de Vos, John L. McDonnell Jr., Mario Balestrieri, Father Paul Schmidt, Father Denis DesRosiers, Brother Martin Yribarren, Craig Hartman, Peter McDonnell, Eileen Ash, Eric Long, Gwelen Paliaga, Mike Brown, Maryliz Smith, Jack Bethards, and Phil Browning.

Advent Lutheran Church, 

Melbourne, Florida

Advent Lutheran Church in Melbourne, Florida is a relatively young church, founded in 1982; services were first held in a realtor’s office. From these simple beginnings, this vibrant ministry has continued to grow in an unbounded manner. When the present sanctuary was built in 2003, they could not fund a pipe organ, but importantly made future provision for an instrument in their new sanctuary; the space provided for the pipe organ and the chamber was sealed closed in the front rock wall of the church.

In 2010, a pipe organ committee was formed. Their study included not only engineering and cost factors, but also the ability to pay for the organ without impacting the operating budget. In 2011, a special congregational meeting was held to approve the purchase of a pipe organ from the A.E. Schlueter Pipe Organ Company, with installation to coincide with the 30th anniversary of the church’s founding.

When I first visited Advent Lutheran with our Florida representative, Herbert M. Ridgely Jr., I found we were blessed with a sanctuary where consideration had been given toward good acoustics and favorable placement for the organ. The front wall of the chancel is a solid concrete wall that lofts from floor to ceiling and is faced with native limestone. Beginning eleven feet off the floor was a 20′ x 20′ opening into the organ chamber. The floor for the organ was a solid poured-concrete slab capable of holding the tens of thousands of pounds of weight required for even a modest-sized instrument.

There are two choir lofts on the right and left sides of the sanctuary. The traditional choir is housed on the left side. The opposing niche on the right side is a space occupied by the accouterments needed for contemporary worship.

With the side locations of the choir lofts, and a sanctuary with more width than depth, our concern was that some choristers or congregants would be “around the corner” from the straight-on frontal exposure of the organ as it speaks into the sanctuary. We wanted to avoid an instrument that emphasized one division over another dependent upon where you were seated.

To provide more uniformity of speech, we planned the removal of the sidewall sections to the left and right of the organ chamber. Adjacent to the side openings were angled wall surfaces that we knew would reflect and refract the sound from the side alcoves behind the chancel wall into the room. These openings were finished with open, ornamental, oak grilles. In the chamber interior we placed the Great and Positiv windchests off-axis from the direct center, so they would be able to speak from the sides as well as the front exposure. The Swell division of the organ is laid out in a side-by-side configuration across the rear of the organ chamber. This minimizes the depth of the enclosed division and allows it to be spatially projected forward in an unimpeded manner to acoustically sit beside the pipework of the Great and Positiv. The result of the additional chamber openings and divisional placement is that the full resources of the organ are evenly heard throughout the room without any significant divisional bias. 

A constant challenge in organ building is having enough space in width, depth, and height. In this instance the internal chamber had “too much of a good thing” in terms of height. The loft inside the organ chamber went well over 25 feet above the top of the frontal opening, creating a significant tone trap that had to be addressed. The solution was to continue the Swell expression box roof over the Great and Positiv. The roof section was built with heavy timbers and made exceedingly thick, which provided an upper surface that was designed to be a refractory angle of incidence across a broad frequency spectrum to focus the organ resources out of the chamber. The end result is an even, coalesced diffusion of sound both inter- and intra-divisionally.

The organ case is built from hand-selected rift-sawn red oak, with a light-colored natural finish to match the church’s interior furnishings. The individual vertical segments of the façade and case are divided into multiple pipe flats that follow the radius of the front wall curvature. In this manner, the façade “bows” rearward from the cross to emphasize it as the central theme in the chancel.

The pipe shades at the top of the pedal towers are evocative of the concrete lace that holds the stained glass within the windows of the church. The polished surfaces of the organ façade pipes play on light in such a way that the façade takes on natural soft, even hues, melding with the church interior. The pipework in the organ façade contains the independent 16′ Principal, and bass registers of the 8′ Principal and the 4′ Choral Bass. 

We designed a terraced, drawknob console for this instrument. In addition to providing excellent sightlines for the organist to see both the choir and the congregation, its lowered profile makes it less dominant against the furnishings in the chancel. The console, including the built-in casters for mobility, is a diminutive 47½ inches tall. The console is built of red oak with a mahogany interior. The interior stop controls are turned of hardwoods with engraved inserts that were custom finished to match the bone and walnut keyboards. The keyboards are fitted with tracker touch.

Ever concerned with ease of registration and ergonomics, we were very careful in our design of the console interior. The drawknob and coupler controls are placed in the traditional locations with the Pedal and Swell stops on the left jambs, and the Great and Positiv on the right jambs. The stops are sequenced by pitch and family, with the primary division choruses aligned to be even to the manual into which they draw. The drawknobs feature oblique heads aligned on straight terraces, and angled inwards toward the performer, making the stops easy to see and draw because the stops on each terrace are within easy reach of the performer. 

For the combination system and relays, we used the new 8400 system from the Syndyne firm. All of the features that one comes to expect on a modern console control system are present—from multiple memories, to programmable crescendos, programmable sforzandos, blind checks, transposers, etc. The system allows centralized control for the combination system, playback/record, MIDI, and other functions, in a single integrated touch screen. One can save or import combination memories from and to an external USB drive, which provides infinite options to the performer. The screen and USB interface allows testing, configuration, and upgrades for the builder without the need for an external computer.

The organ chests are a combination of Blackinton-style electro-pneumatic slider chests and electro-pneumatic unit action chests for unit and duplex stops. 

The main manual chest winding system makes use of traditional spring-and-weight, ribbed regulators, and floating lid regulators that are fed from a large, central plenum. The enclosed reeds are provided with separate regulators to allow a pressure differential from the flue stops and permit independent tremulant control. All of the windchests are individually fitted with tunable concussion bellows for fine regulation. This allows stable winding that still maintains a presence of life.

Wind pressures on the organ are 3½′′ Great, 4′′ Swell flues, 5′′ Swell reeds, 2¾′′ Positiv, 3′′ Pedal and façade, and 8′′ for the Solo 8′ Festival Trumpet. The tremolos are electro-mechanical to provide a quiet, gentle, even undulation when the tremulants are engaged.

Prior to designing a stoplist, I find, as an organbuilder, it is incumbent to worship with the congregation. This cannot be a one-time event, as a church’s liturgy as it moves through the year is a rich pageant that cannot be conveyed, but has to be personally experienced to put the worship service in your own eyes, and more importantly your own ears. Personally, I find it illuminating to look into the eyes of the congregants who have asked me to build an organ for them. It instills me with the gravity of the task at hand and becomes a constant that I draw on throughout my working with the church. 

As I designed the stoplist, I envisioned an instrument where all of the resources could be considered for use in every service. I wanted a large enough specification to provide a rich palette of color and weight. It was important to avoid any sounds that were strident or overwhelming, as they didn’t have a place or use in this setting with this congregation. The ideal stop design would emphasize reliance on chorus massing to bring about larger stop dynamics which build upon one another. The goal was to design a specification that would allow gentle, sculpted voicing. 

Because of the German origins of the Lutheran church, I knew there would have to be an inclusion of the “Werkprinzip” in the specification. However, I also felt strongly that a single nationalistic focus would have been too limiting for this congregation. Ultimately the design of the instrument included many tonal facets that allow the organ to be a faithful purveyor of music from many periods, styles, and nationalities, in a cohesive, eclectic manner. Those who are familiar with our collective body of work will find present the balance of clarity and warmth that we seek in all of our instruments.

As we designed the principals, flutes, and strings in this instrument, we employed differing construction and materials in conjunction with careful scaling. The varied use of wood, metal, open, semi-open, stoppered, cylindrical, conical, and other variations, allow each flue stop its own unique voice and timbre. 

The organ is centered around the clean, robust principal chorus of the Great division. The 16′ Sub Principal of this division transitions from the façade into the slotted pipes of a Geigen Principal, which allows a thinner, defined register to ground the Great chorus. This stop is duplexed to provide an 8′ foundation for the Positiv principal chorus, and allows doubling of the 8′ line when coupled to the Great. The Great 8′ Bourdon and 4′ Nachthorn, in addition to being lovely solo voices, are valuable as thickening agents to the Great principal chorus, without overshadowing it. The enclosed Swell reeds are duplexed to the Great, which provides dynamic control of these stops by their enclosure.

The mixed media of wood, metal, stoppered, and open construction continues into the flutes of the Swell Cornet decomposé. These stops envelop one another and become almost svelte in their combined voice. The Swell Cornet is countered with a secondary principal-based Cornet in the Positiv division. In a departure from common practice, the individual Positiv mutations are placed on unit actions, which allow use of these stops at a variety of pitches and combinations. This becomes very useful for color and ornamentation and also facilitates the beginnings of building weightless mixture texture in the organ divisional ensembles by drawing these independent fifths.

For this instrument, we chose to employ strings of opposing qualities in the Positiv and Swell divisions. The Positiv 8′ Erzahler has a gentle broadness with a subdued edge-tone. It can support the most quiet and contemplative of moments in the service, and yet has enough body that, when coupled with the 8′ Holzgedeckt, provides the foundation for the Positiv principal chorus. In the Swell division, the gambas with their thinner scales, roller beards, and slotting have a keen and incisive, harmonically rich voice. These stops leave little doubt that they are strings and have a very distinctive edge-tone. The 8′ Gamba when drawn with the 8′ Rohr Gedeckt provides the foundational weight for the Swell principal chorus, and a compounded color that would be analogous to an independent 8′ Violin Diapason. 

With their large dynamic, the majority of the reeds were placed in the Swell enclosure. The 8′ Festival Trumpet is moderately scaled on relatively high wind pressure. With its thinner scaling and placed under expressive control, it can be registered into the full Great and Positiv choruses as a thinner ensemble reed when the expression box is closed. With the box open, it is an incisive, tightly drawn color that can bring a blaze to a solo line. The Swell reeds include a double tapered Oboe with lift lids and a large vowel cavity at 16′ and 8′ pitch, which balance against the éclat and fundamental of the large-scaled 8′ Trompette. 

The unenclosed manual reed on the organ is the 8′ Krummhorn in the Positiv division. It is built of brass with flared lift caps. By itself it is a very useful solo and/or ensemble stop, with the nose tone of a regal class of reed. It also effectively couples with the 8′ Holzgedeckt to provide a stop eerily reminiscent of the woody voice of a fine clarinet.

The Pedal division is grounded with three independent 16′ stops, including a large 16′ Posaune. It is a very complete pedal, with the gravitas to support the full forte of this instrument. The Pedal stops were given a forward position to eliminate shading and to allow gentler voicing. The result is a buoyant and harmonically rich pedal, where the inner voice is ever present. In addition to the independent registers, there are a number of manual-to-pedal duplexes, which broaden the available weight and color choices. 

The organ tonal finishing was accomplished by a team consisting of Arthur Schlueter III, Pete Duys, John Tanner, Bud Taylor, and Marc Conley. The organ was first used for worship in December 2012 and was dedicated on January 20, 2013 by organist Peter B. Beardsley. 

Every organ project has those individuals without which the project could not have been possible. In addition to thanking every single member of the congregation, the church council, and the organ committee, I personally want to single out senior pastor Reverend David Jahn, organist Lori Jahn, executive assistant to the pastor Carol Stanton, and organ committee co-chairs Pat Fuller and Jack Clark, for their very direct, hands-on work with our firm throughout this project.

Organ building is not the work of one person, but is a plurality or culmination of talents. We are very fortunate to have so many talented craftsmen and craftswomen at our firm. Our staff includes Arthur Schlueter Jr., Arthur Schlueter III, Shan Dalton, Marc Conley, Patty Conley, Bud Taylor, Robert Black, Dallas Wood, Al Schroer, John Tanner, Pete Duys, Barbara Sedlacek, Patrick Hodges, Jay Hodges, Kelvin Cheatham, Jim Sowell, Bob Weaver, Ruth Lopez, Michael DeSimone, Bill Zeiler, Chad Sartin, Steven Bowen, Jeff Moore, and Herbert M. Ridgely Jr.

An essay in determination

The quest to replace a six-stop unit organ in Oklahoma City became a study in considered choices made by a fully involved group who gave to the future an instrument that serves worship, choral programs, solo recitals, and orchestral concerts. The organ committee at Mayflower Congregational United Church of Christ, in cooperation with their pastorate and director of music Richard Jobe, worked with consultant Scott Riedel of Milwaukee to develop an architectural, acoustical, and musical plan. They enthusiastically educated themselves, traveled the nation to see and hear instruments, and selected their architects, contractors, and organbuilder.

Living with a mid-twentieth century stock-design instrument, the church was moving from a position of extreme limitation to one of enormous freedom–and its attendant responsibility. It was known from the outset that the stoplist would evolve; omissions would be reinstated, new ideas would be raised and abandoned. That is how pipe organs are refined toward their final design once the builder is selected, a process that at times both disappoints and elates during the pursuit of cleverness. 

There was no focus upon an idiom that would back the organ into a stylistic or nationalistic corner. Mayflower’s instrument is by all means an American pipe organ, from its geographic location to the fact that its components were built by Americans in selected shops throughout this nation. Nonetheless, the term “American Classic” never entered our thoughts or vocabulary. That era remains a crucial and brilliant transition, to be acknowledged for its contributions, but it was dotted with obstacles to the full understanding of organ literature and history. Many of its lessons still apply, but should its templates?

 

Architectural placement

The spatial arrangement of pipe organs has been under discussion for centuries, as evidenced by myriad cyclical catch-phrases—“mixing chamber,” “line-of-sight,” “functional display,” “high and encased,” “tone chute,” and “entombed.” All incarnations present compelling effects, from jumping between main and dorsal cases in a North European organ, to the roaring, shuttered reeds scraping at the triforium of an English cathedral. The choice at Mayflower UCC was an arrangement that addressed the new chancel and choir area as if it were a concert hall, surrounding the proceedings with four well-engineered, highly effective chambers that were proximate enough to cooperate without losing individuality. Rigid walls, properly shaped ceilings, and thick, tightly fitting shutter blades make for an enormous range of amplitude.

 

Tonal development

Traditional structure—independent Principal forces for at least two manuals and the Pedal—anchors the organ in terraced levels of open tone at 16′ for the Pedal, 8′ for the Great, and 4′ for the Swell. The Pedal has no chorus, per se, but a dedicated, extended rank retained from the previous instrument, voiced so that movement of the pedal line is heard. An additional 8′ Open Diapason, extended up from this Pedal stop, is enclosed with the Choir division. There was no room in the Swell for a desirable 8′ Principal, but this voice serves as an English Second Diapason, as well as a solo under expression to be accompanied by other divisions.

The Pedal 16′ Contra Bass is not intended to be a 16′ Principal, but to add definition through distinct tone and a substantial degree of independence from the unit rank. Making evident the motion of the pedal line was the goal, and it works as well under full forces as it does under the two undulants during introspective passages. Pedal power comes from the 16′ Sub Bass, the 16′ Trombone, and the harmonic complexity of duplexed mezzo-forte voices from the compound Great/Choir section. 

The mixtures are kept to an even number of ranks for harmonic balance, and achieve different effects. The Great Mixture is unenclosed, speaks directly down the nave, sits at the front of the soundboard, breaks successively lower, and keeps its quints two scale diameters smaller than the unisons, resulting in a fuller treble. While I am personally disinclined toward the guttural infusion of a bold twelfth entering the chorus too far down the compass, it was eased in carefully during tonal finishing, avoiding the “pull,” and in this case, actually appears to strengthen the alto voice in the middle and soprano octaves. The Swell mixture breaks less frequently, maintaining a slightly higher aggregate pitch in the contrapuntal range, the shimmer enhanced by power parity between harmonic components. Toward the top of the compass, a larger-scaled 8′ pitch enters to fortify the unison line in the absence of an independent 8′ Principal.

 

The compound Great/Choir

Between the wars, Mr. Skinner’s three- and four-stop Choir divisions unintentionally opened a window onto Classicism for those Americans who had looked beyond the vested American zeitgeist during their overseas travels; in recent organs, I have followed his lead with very small third manuals that can make playable more of the literature with satisfying accuracy while enhancing the service of prayer. 

I was determined not to make the Choir a garage for miscellanea at the expense of filling out the Great, and recommended to the consultant and the organ committee that we strip and releather Mayflower’s original six-stop unit windchest to accommodate enclosed voices that could both embolden the Great and furnish a small Choir division. Four of the organ’s seven ranks were revoiced and incorporated, while the Clarinet and Harmonic Flute are new to the organ. 

The key was to make certain that independent voices could be drawn at each pitch, and that if two stops on the same division were drawn from the same rank, we strive for a two-octave separation to minimize “missing pipe syndrome.” The benefits are an elegant, clear third ensemble punctuated by the sparkle of the 1′ Gemshorn, an historically dictated position for the Clarinet, and the nuance enabled by a second expression enclosure. The Great gained the indispensable 8′ Harmonic Flute for the French literature and a solid 16′ Bourdon to carry hymnody and undergird the plenum.

 

The mutations

For an instrument furnished with only one tierce combination, published works—both treatises and scores—from the 17th through 19th centuries provide guidance. Historically ensconced in the Choir or Positiv, the cylindrical half-length reed (here the Clarinet) cannot be roommates with the Tierce combination and perform the French dialogues of the Baroque (why deprive future organists of that option?), and it is well unwise to lock up two of the most pungent solo effects on the same manual. The Nazard and Tierce (originally conceived as a Cornet II until funds made it possible to separate them), reside in the Swell, benefiting from the recombinant capabilities of the fully independent flute choir, and where they can engage with the reeds for the fiery Grand Jeu, an effect unique in the world of music.

 

The undulants

The Choir Gemshorn and GG-compass Vox Angelica are the source for gentle tone with more slowly tuned undulation. They were well-made pipes that the church already owned, and with revoicing and tonal finishing, they serve well in services of prayer; sacrificed were the likes of an English Horn and a bit more Choir independence, both of which had been on the “wish list.” By contrast, the Swell strings are authentically brilliant, cutting, shimmering, and unapologetically orchestral, taking the vibrantly tuned undulant all the way down to 8′ CC. This type of tone, desired and characteristic during the fourth quarter of the 19th century and well into the last, is vital to the performance of the literature and should not be diluted.

 

The three reed stops

The reed allotment challenge in a small organ is one of both color and pitch. The three historically primary colors (Trumpet, Clarinet, Oboe), and relative unison pitches (8′ for the manuals, 16′ for the pedal) jockey for position, and the balance tips inevitably when one is limited to a single rank of Trumpets that is hoped might fulfill the needs of the Great, Swell, and Pedal departments. The dilemma of rationed budget and space is not new, and Americans have faced it for decades. It is for this reason that I chose to place the organ’s three reed stops on individual electro-pneumatic valve actions and present a candid acknowledgement of the available assets. Tonal directors choose sleights of scaling and make accommodation in the voicing so that musicians might take their cues from the resulting resources. If the conservative builder or designer chooses not to sustain the compromise, the clients and their successors must manage without. 

Carrying the chorus reed burden of the entire organ, the Mayflower Trumpet is large, bold, brilliant, and must be handled with care. Fortunately, it could be scaled and voiced with abandon as it descends into the Pedal 16′ Trombone extension where it needs not serve two masters. Part of the rank’s success is that it grows toward the bass in the French tradition, and there is no 4′ Clarion extension to pierce and fragment the grandeur.

The Swell 8′ Oboe d’Amore, extended to 16′ as the Bassoon, is firm, full, and warm, avoiding nasal tone in favor of a plump, round voice that is essential to the fonds d’huit. The richness achieved with full-length resonators facilitates blend when introducing milder reed tone into ensembles for textural buildup or choral accompaniment. In the American tradition of the last century, it is duplexed into the Pedal at 16′ and 8′ pitch. 

The Choir 8′ Clarinet makes no concessions, free to be gutsy, woody, and forthrightly characteristic. Highly identifiable to the “non-organ” ear (the target audience of the future?), the evocative, orchestral style of Clarinet fulfills the needs of both the solo and anthem literature in lieu of a caricature voice that might elicit questions of taste or judgment. The Clarinet is made available in the enclosed Great II section so that it can be accompanied by stops from its own department, and appears in the Pedal as a cantus firmus voice.

 

The 32′ stops

The new acoustic at Mayflower could support gently balanced 32′ tone, but there was no available space for the pipes. Resultant basses almost never work effectively in American organs, although they appear to be standard equipment, false hope in the form of a switch. They succeed in brief ranges, with certain scales, and with pipes of particular tonalities, but only if carefully placed in relationship to their neighbors and to the physical structure that houses them. The failure rate is compounded by the assumption that any stopped flute will suffice and that physics will intuitively provide a musical effect. Fortunately, the Mayflower 16′ Sub Bass is of the scale, cutup, voicing, and positioning that it produces an unobtrusive and pervading 32′ tone without muddying the waters.

Now that weight had been achieved, something unusual had to be introduced. What would prove to be most interesting? Resultant 32′ Dulcianas date back at least to Hilborne Roosevelt’s 1879–1883 double organ at the Cathedral of the Incarnation in Long Island City. The concept resurfaced in 1922 in Casavant’s tonal recasting of the 1902 Hook & Hastings built for Temple Beth-El in Detroit, but the Mayflower 16′ open metal proved too incisive and exposed to achieve such an effect with the desired subtlety, so I opted for a hint of spectacle. Cavaillé-Coll’s 1880 organ for La Cathédrale Saint Croix in Orléans sports a clamorous 102⁄3′ Bombarde, breaking to 32′ at C13, labeled Contre Bombarde. While such noise would be utterly inappropriate at Mayflower UCC, the transfer of this effect to the Bassoon is telling but unobtrusive.

 

The console

The keydesk was inspired by the Aeolian organs for the homes of the aristocracy during the nation’s Progressive Era, and further informed by later Hook & Hastings consoles. The balanced tablets on side jambs permit the musician to “read” the specification quickly and clearly; each field of stop controls is in the same location that it would be if drawknobs had been used. It glides less than half an inch above the floor with the gentle push of a hand as it is repositioned for its many uses in association with Mayflower’s ministries. As with all Glück consoles, it is equipped with a high-capacity combination action, MIDI interface, and record and playback capabilities, yet the clutter of gadgetry is kept to a tasteful minimum.

 

The visual design

When developing organ cases, I call upon my university training as a preservation architect to develop visual statements that take their cues from their surroundings. Ornamentally and proportionally, this firm’s new instruments appear as though they had always been in the buildings they serve. A relaxed presence and æsthetic harmony are achieved through the use of sympathetic materials and elegantly adapted details that are meaningful to the community. The classical arcuated pediment of the central window, the visual focus of the church since its construction in 1957, served as my guide. Where there were once two blank, sheer walls now stands a pair of pendant cases that echo the ceiling vault and the central window in order to accommodate the unenclosed Great I and Pedal Contra Bass.

 

Putting it all together

Pipe organs are made real by teams of people, and this firm’s lean business model benefits from collegial cooperation. The staff at Glück Pipe Organs, including Joseph DiSalle, Albert Jensen-Moulton (general manager), and Robert Rast (chief technician), was supplemented by students from the American Organ Institute at the University of Oklahoma and volunteers from Mayflower Congregational Church during the removal of the church’s original pipe organ and the installation of the new one. Along with the trusted American suppliers with whom this firm has worked for over a quarter of a century, they liberated me to focus upon the design, scaling, voicing, and tonal finishing, with a view toward the artistic and musical outcome.

Scott Riedel, working with both Glück Pipe Organs and Steve Matthews, principal and project manager at Architectural Design Group, made it clear that consultants do not choose pipe organ builders, but guide institutions toward educated decisions—not hopeful guesses. The joy with which this project came together is heard in the sound of the pipes, and we are thankful to have been chosen by this growing church, educational center, and outreaching community unique in Oklahoma City.

From the choirmaster

When I assumed my duties during the summer of 2010, discussions about a new chapel organ at St. Mark’s School of Texas had been ongoing for several years. The previous chapel instrument was originally designed and built for the school’s Collegiate Chapel, which was subsequently demolished to make room for a significant campus expansion. When relocated to the current chapel, the organ was under-scaled to the point of almost disappearing when the room was full; it was quite simply too small for the room. Further, the organ began to experience problems in the spring of 2011, with the pièce de résistance being the entire Pedal division falling silent during a chapel service.

In a meeting with then Headmaster Arnold Holtberg, he encouraged me to form an organ committee to work towards a new pipe organ for St. Mark’s chapel. I also hired David Heller, organist and chair of the music department at Trinity University in San Antonio, Texas, to serve as our consultant. Over the course of several meetings, our committee determined that our selection criteria consisted of the following:

• Ability to accompany a choral ensemble

• Ability to lead a worship service

• Performance of organ repertoire—
for worship and concert

• Proven excellence in the building
of electric-action pipe organs

• Creative designs, both visual
and tonal.

 

After an exhaustive search that concluded with on-campus presentations by three organbuilders, we awarded our project to Orgues Létourneau of St-Hyacinthe, Québec. We were impressed by Létourneau’s world-wide reputation for excellence in organ design and building, and also by the breadth of their instruments—the company produces not only large instruments for churches and concert halls but also small and mid-size instruments. We were gratified to see all Létourneau organs share the same high quality and attention to detail throughout.

I had the privilege of traveling to St-Hyacinthe in February 2014 to see the almost-completed instrument with Dr. Heller. I knew upon entering the Létourneau workshops that we had made an excellent choice; the quality of the materials and craftsmanship all pointed to an exciting finished product. Later that day when I entered the building where Opus 127 had been erected, I was overwhelmed with the beauty of the casework and the overall design. It has been so gratifying to hear many people remark over the past few months that the organ looks like it was designed along with the building—that it “looks like it has always been there.” This is indicative of the careful attention from concept to design to construction of the Létourneau team.

Opus 127 was delivered on September 3, 2014, and was first played in a service of Choral Evensong on November 11. Our organist, Glenn Stroh, played an extended prelude to the service, which opened with Gardiner’s Evening Hymn and concluded chorally with Mathias’s Let the People Praise Thee O God. Opus 127 did not disappoint; from the quiet opening notes of the Gardiner to the raucous conclusion of the Mathias, all in attendance were enraptured by the wide variety of color and the seamless way in which the instrument uplifted both the choir and the congregation singing. Dr. Heller played a dedication recital on January 11, 2015, in which he explored every niche of the organ’s vast tonal palette.

I am so grateful to all those involved in this project, from our fantastic committee to dedicated administrators to our donors, for giving this gift to the St. Mark’s community. This pipe organ is a gift of music that will inspire students, lead in worship, and enhance the spiritual life of St. Mark’s for many years to come.

From the organist

The arrival of the Roosevelt Family Pipe Organ marks a significant milestone in the life of St. Mark’s School; it is the culmination of a long-held vision for an instrument designed especially to support the needs of our community.

As organist, I am excited and privileged to be able to pilot Létourneau’s Opus 127 through the many programs for which it is used at St. Mark’s, but the real value of the instrument lies in the substantial ways it has already enriched the lives of students, faculty, and guests. The installation and mere presence of an instrument like this is a wonderful and unique educational experience for our students. It is an extraordinary thing to have an organ like this in a school chapel, where some 850 young people may hear and interact with the instrument regularly. We are in the business of instilling and nurturing curiosity in our students, helping them through the course of their exploration as they learn more about themselves and the world around them. The joy of discovery, so readily seen in the faces of students as they encounter the new instrument, is rewarding and gratifying for all involved in this project.

From the beginning, the school’s reputation for excellence and its mission to provide a complete education to the young men in our charge demanded the highest possible standard. We are blessed with a fine acoustic in the chapel and space in the chapel’s rear gallery, an ideal placement for such an instrument. The organ has had an immediate positive impact in the daily life of the school, supporting vibrant music for our chapel services, school ceremonies, and fine arts programs. Given the Anglican tradition of choral singing upon which the St. Mark’s Choir was founded, the instrument was designed with the role of accompanying a choir and supporting congregational singing at the fore. Opus 127 easily facilitates expressive and dynamic accompaniment and has the ability to swell from a nearly inaudible pianissimo to the power of full organ. The English Tuba provides a particularly powerful solo voice to complete the specification. Special demonstrations of the organ have sparked interest from students and adults alike; the larger community has likewise enjoyed recitals by David Heller and James O’Donnell, organist and master of the choristers at Westminster Abbey.

I am immensely thankful for the support of the campus community, the generosity and commitment of donors, the many hours given by the organ committee, the excellent work from various members of St. Mark’s staff in preparing the chapel for the organ, and the fine craftsmanship and skill of the many Létourneau employees involved with this organ. This instrument will inspire many generations of future Marksmen, and I applaud the vision and dedication by all involved in this process.

From the builder

The muse for the organ at St. Mark’s School of Texas was encountered on a 2012 study trip to England. We saw many instruments on this trip, but a visit to St. Dominic’s Priory in North London stands out as having destroyed some preconceived ideas about British organbuilding. Completed in 1883, the organ at St. Dominic’s is a “Father” Willis and it stands today in largely unaltered condition. Upon arriving in the church, the titular organist, Martin Stacey, cannily introduced us to the Willis with the opening Allegro movement from Widor’s Sixth Symphony. The organ’s vigor and polish were on display from the opening chords; the effect was astonishing. Here is why Father Willis’ organs were controversial in their day: the sound is dazzling—even sensual—and like nothing else.

Within a year of this trip to England, we were contacted by St. Mark’s School of Texas and asked if we would put forward a proposal for a new pipe organ for their chapel. St. Mark’s School is renowned as one of the finest boy’s schools in the United States. Their chapel services have long been anchored by the school’s boy choirs and this choral tradition continues to the present day. When pondering what type of instrument would best serve St. Mark’s School, our thoughts turned to English boy choirs and the fine organs whose sounds are synonymous with soaring boy trebles. Though the St. Mark’s School organ would be larger, the Willis at St. Dominic’s Priory came to mind as a source of inspiration with some deference to the organ’s raison d’être of accompanying young vocal ensembles. After our presentation in July 2012, the school’s organ committee enthusiastically endorsed our vision and an agreement was concluded a few months later for the construction of a new 61-rank pipe organ.

A range of 8′ foundation stops throughout the specification permits deceptively smooth shifts in color and intensity. The large, elegant Great 8′ Open Diapason gives way to the milder Swell 8′ Open Diapason, while the Choir 8′ Geigen Diapason is yet another dynamic notch softer and has tapered pipes for a different timbre. The Great 8′ Salicional is a broad string rank with sufficient presence to color the other foundation ranks, including the treble-ascendant 8′ Harmonic Flute. The Swell division has a 16′ Contra Gamba stop with Haskell tubes to save space while preserving prompt speech; the corresponding 8′ Gamba and 8′ Voix Celeste are typically keen. The Choir 8′ Dulciana and 8′ Unda maris ranks offer a neutral string tone, with the Dulciana blending chameleon-like with other mezzo piano stops. The organ’s softest stop is the otherworldly 8′ Flute Celeste.

The influence of Willis is seen in the organ’s plenums with the inclusion of tierce ranks as well as modestly scaled upperwork with narrow mouths. Reed stops feature tapered shallots with triangular openings exclusively; chorus reeds are on higher wind pressures than the flue stops for additional power. The 8′ Vox Humana was specifically modeled after an example by Father Willis with slotted cylindrical resonators, while the 8′ Tuba sounds on 12 inches wind pressure and features hooded resonators made entirely from spotted metal. The Tuba speaks effortlessly down the chapel from its perch directly behind the Choir expression shades.

The Pedal division is robust and is undergirded by a generous 32′ Bourdon and a 32′ Contra Trombone with half-length resonators in wood. The complete principal chorus is capped by a three-rank Mixture that includes a 31⁄5′ rank giving a distinctive growl to pedal lines in counterpoint. All manual 16′ stops have been borrowed to the pedals for additional flexibility when accompanying.

The organ’s internal layout is straightforward and spacious. The two expressive divisions are stacked behind the center of the oak case with the Swell below and the Choir above. On either side of the expression boxes, the Great is divided into C and C# chests on the upper level with the Pedal likewise split below. The organ’s 16′ façade displays polished tin pipes from the Great and Pedal principals. The organ is played from a compact three-manual console that includes 256 levels of memory with 16 general pistons and a general piston sequencer (or stepper), a Great-Choir manual transfer, an All Swells to Swell function, independent combinations for the Pedal stops optionally operating from the Great or Swell divisional pistons, and a record-playback system.

When told we had been chosen to build a pipe organ for St. Mark’s School of Texas, we were honored to know the Létourneau name would be associated with such a dynamic institution. Throughout the months that followed, it was never anything short of a pleasure to work with everyone we encountered to a person. Further, the enthusiasm shown by the staff and especially the students towards the Roosevelt Family Pipe Organ has been most gratifying and encouraging. We are grateful for having had this opportunity and trust this instrument will serve the school and its worship faithfully.
