From the organist
Nearly a decade ago, St. Philip Presbyterian Church began planning a major renovation of its facilities. In addition to a new educational building, plans were made to gut the sanctuary and make it a more vibrant and flexible space. By 2004 a new organ was on the horizon as well, thanks to an old electric-action instrument whose shortcomings had become obvious, an enthusiastic committee, and an expert consultant. In 2005 we bid good-bye to the old sanctuary and organ and signed a letter of intent with Paul Fritts for his Opus 29, a three-manual and pedal mechanical-action instrument of 48 stops, which was delivered and installed in the renovated sanctuary in early 2010.
And we couldn’t be happier! The new organ and sanctuary are a perfect match, with the instrument speaking directly into the room from its lofty position in a new gallery. Significant changes had to be made to the former choir loft to support the new organ, with the new gallery extending forward into the sanctuary to accommodate both choir and organ. Fortunately, we were blessed with a building whose basic shape—tall, long, and slender—presented a potentially ideal acoustical environment for organ and choral music. The transformation has been stark: a room that formerly had abundant absorptive and soft surfaces now has several seconds of reverberation. It’s also become a much more appealing visual space: the modernist light-filled sanctuary now boasts handsome millwork, beautiful stained glass, a tile mosaic front wall, and in the rear gallery, a stunning new organ.
Our selection of Paul Fritts & Co. as builders reflects St. Philip’s longstanding commitment to excellence in its music program and the amazing foresight and generosity of its members. Now just a little over a year old, the Fritts organ has generated a great deal of local and even international enthusiasm, and we’re delighted to be sharing it with a wide community of music lovers. I’m especially pleased that organ students from the University of Houston are able to use Fritts Opus 29 for weekly practice and degree recitals, since a splendid instrument like this has so much to teach us.

From the organ consultant
Long before I became the consultant for a new organ at St. Philip Presbyterian Church in 2004, Matthew Dirst set the groundwork for the project. For many years he had developed a solid relationship of trust, goodwill, and mutual respect between himself and the musicians, clergy, and congregants of St. Philip. It is certainly safe to say that without that special relationship, this project would never have happened. Soon before I came on board, an organ committee had been formed and fundraising had begun. I quickly learned that music was very important to the people of St. Philip. The committee made clear that they wanted an instrument that could lead in worship, accompany the choir, and make possible the performance of great organ music—especially music played by their world-famous organist! But something else came through from our initial meetings. The committee wanted an instrument of high quality that would stand the test of time, and of real beauty that would lead people to a fuller spiritual life.
The committee considered several builders. Committee members took their responsibilities seriously, and some of them made trips well outside the state of Texas to hear recent installations. As soon as they heard the Fritts organ at the University of Notre Dame, they knew what builder they wanted for St. Philip. The size of organ was never the driving force, and in fact the church initially contracted for a smaller (and less expensive) two-manual instrument. I know Matthew Dirst would have been content with it. But additional funds became available, and the size and scope of the instrument increased accordingly.
Besides the desire for a quality instrument that could lead in worship and be featured in concerts, the people of St. Philip Church wanted an instrument that could be used for educational purposes. The organ majors of the University of Houston now practice on this instrument almost every day, take weekly lessons at the church, and present degree recitals on it every semester. Last year, the church began an internship program, which lends support to one lucky UH graduate student in organ. In its role as music educator, the instrument will be featured in numerous conferences and workshops in the years to come, including a national conference sponsored by the Westfield Center for Early Keyboard Studies to be held April 12–15, 2012, and the AGO national convention, scheduled for the summer of 2016. We are most grateful!
My congratulations go first to Matthew Dirst, Associate Professor of Musicology at the University of Houston and organist of St. Philip Church, for his many years of strong leadership and impeccable musicianship. He really deserves such an instrument! I also want to thank the St. Philip Organ Committee—especially its remarkable chairperson, Elizabeth Duerr—for years of hard work and unwavering commitment to excellence. And, finally, thanks go to Paul Fritts and his entire team for the construction and installation of an instrument of real quality—one that I know will inspire the congregants of St. Philip and the citizens of Houston for many years to come.

From the organbuilder
Many decisions contribute to the building of an organ, and these decisions become more significant when virtually every part is designed and built in the builder’s workshop. This distinction, achieved by our firm in 1984 when the pipe shop was established, enables creativity to flourish—we can build anything we want.
Organbuilders have been practicing their art for centuries, often with extravagant support. Today we can visit existing organs from most periods and national styles and still experience them firsthand. These visits become more challenging since we must also account for things outside the original builder’s intention. We are experiencing instruments through the veil of rebuilds and restorations over the centuries, some not so sensitive. We must also develop a good understanding of the acoustical environment these organs are speaking in, often a far cry from the typical modern American space. We can both experience how these organs sound and behave today, and also imagine how they once were.
Over the course of many study trips, I have noticed things common to instruments I consider magical. Interestingly, these outstanding instruments are not limited to any national style or time period. When comparing the experiences, I find a substantial convergence in areas of sound. The sounds of the pipes are complex and yet they have an unusual combination of qualities often difficult to achieve but deliberately sought after: their harmonic content is both refined and colorful, and it is balanced with a generous amount of fundamental. The speech is quick and elegant. These qualities are especially challenging, since customary ways of refining speech generally kill the unique harmonic content we hear in the old pipes. Interestingly, we find these sonic qualities in other fine instruments: violins, harpsichords, pianos, and many others. There seems to be a connection to the human voice—richness is present, combined with clarity—and all of this is accomplished, in the case of the organs, without excessive intensity, through the use of relatively low wind pressure. The organs somehow function on a human scale in spite of being grand both in appearance and sound. The pipes have open feet and flueways and relatively high cutups, but are mostly controlled in their sound production by the organ’s wind pressure, the main determinant of the organ’s overall intensity. These things contribute to what has been aptly called a relaxed intensity—the pipes sing robustly without shouting. Many other aspects fall into place when stops are working this way. The blend between them is enhanced and many more stop combinations work together. The organs carry a space remarkably well without having to be loud. They lead rather than direct a congregation. This rather strict approach surprisingly enables an organ to be more eclectic or universal in its capabilities. And, most importantly, they are supremely musical.
These thoughts were on our minds as we considered the design and construction of the new St. Philip Presbyterian Church organ. Many ideas garnered from the study trips expand the design, construction, and voicing, along with the collective experience of our seven craftsmen. The case appearance, in keeping with the spare nature of the church architecture, is an original design and incorporates ideas found in revered cases to make it more interesting. The treble flats curve inward and alternate direction in ancient Dutch fashion, and the proportions of the bass and tenor flats follow well-established trends. Straightforward moldings properly adorn the case and each vertical stile is framed with decorative insets. The carvings are contemporary creations inspired by Renaissance-era Italian organ pipe shades. All is painted a glossy white with gold leaf highlights. The result in the church is both a striking appearance and a comfortable feeling that it belongs.
Tonally the organ is more strict and at its core Germanic. Arp Schnitger’s work forms the basis of our recipe, and for good reason. The level of sophistication in the pipe-making and voicing is a true inspiration. Congregational support is of paramount importance and was at the forefront of our thinking when envisioning the St. Philip tonal design.
There is an abundance of reed stops, and these pipes follow the same principles as the flue pipes. They are made to produce a strong fundamental tone combined with color and refinement. The resonators are cut long to facilitate this, and a welcome consequence is tuning stability.
Eclecticism within this structure can flourish. For the St. Philip instrument we have included many stops and features that broaden the scope. A Swell is present with shades on three sides, along with the required string stops plus the Hautbois (a strict Cavaillé-Coll copy) stop. A string stop is also present on the Great, and there is a wide variety of flutes throughout the organ.
We have also added an electric stop action piggybacked to the mechanical stop action. We do this since there is a vastly different life span between the two systems. Any electric computer system will fail within a relatively short time compared to a well-made mechanical system that can function for centuries. We can avoid this dilemma if the electronic components are included in a non-intrusive way and are easy to replace when it becomes necessary. In the meantime, the organ will not be seriously disabled by failures of these electrical components, since the mechanical system will continue to work. As is usual with modern electrical preset systems, there are the usual features, including hundreds of memory levels and a sequencer.
The wind system is substantial, with four large bellows fitted with all the levers and check valves necessary to foot-pump the organ. When this novelty is utilized and the audience is informed, the performance takes on new meaning. There is a connection to the organ’s legacy—the organ is functioning on a human scale.
All of the four divisions speak directly through the façade—that is, no divisions speak through other divisions, contributing to an easy balance among them. The manual divisions are positioned center case, with Positive at the bottom, Great above, and Swell at the top. The Pedal is divided on each side.
The people of St. Philip Presbyterian are to be much admired for their unyielding support throughout the process leading up to the dedication of the organ in the spring of 2010. I am also humbled by my talented staff who work skillfully and with dedication. We strive to build lasting instruments—instruments that are both durable and very much cherished by those who play them and those who listen. Projects like this have the added benefit of the involvement of a wide group of people, a group too numerous to individually name here. I thank the St. Philip family for their support on many levels throughout the process, and I thank my wonderful crew for their continued excellence and support.

Zion’s Lutheran Church, East Germantown, Indiana

Michael Rathke

A native of Indiana, Michael Rathke received his early organbuilding training with Goulding & Wood, Inc. He subsequently served a formal five-year apprenticeship plus a further two journeyman years with C.B. Fisk, Inc. In 2002 he traveled to England to work with Mander Organs, assisting with the refurbishment of the 1871 Willis organ in London’s Royal Albert Hall and the restoration of the 1766 George England organ at the Danson Mansion in Kent. Upon his return to the United States in 2004, Rathke established his own workshop, where his focus continues to be the building, restoration, and conservation of fine mechanical-action instruments.

I first visited Zion’s Lutheran Church in 1986, near the beginning of my organbuilding apprenticeship. I recall surprise in discovering that the venerable M.P. Möller, with whose plentiful local electro-pneumatic installations I was familiar, had once built mechanical-action instruments. If Zion’s organ were representative, Möller’s tracker output had clearly been more than respectable. Apart from a stiff key action, the organ was a pleasure to play, and its 16 stops made a grand sound in this relatively small church.

My next visit came 25 years later, shortly after setting up my own workshop nearby. On this occasion I was less struck by the Möller’s quality than by its evident deterioration. The organ looked fine, having recently received cosmetic repairs; its basic sound also remained fairly convincing, if not precisely as I remembered. But mechanically, the organ was a mess. The key action was heavy, sticky, and unpredictable; both manual windchests were suffering from obvious and severe sponsil damage; and the two reservoirs (supply-house units that had replaced the original double-rise) were living on borrowed time. Ciphers that could not be rectified abounded; other notes would barely play because their channels had been excessively bled to alleviate sponsil ciphers. The parishioners of Zion’s remained proud of their historic organ, admired its sound, and affirmed that it had served well since arriving in 1933 from a neighboring church. But it had also been an ongoing maintenance challenge. This vigorous but small congregation was understandably weary of spending money at regular intervals and being assured time and again that the organ was now “good as new,” only to find that each assurance had been optimistic, at best. 

When we were asked to take over the organ’s routine tuning and maintenance, we were also charged with making appropriate long-term recommendations. Our first was simply a year of watchful waiting, during which we proposed to carry out touch-up tuning and minor repairs but to do no major work, striving to keep near-term maintenance spending to an absolute minimum. We were thus able to observe the Möller through a full cycle of heating and cooling seasons, especially important given its location partly within an uninsulated organ chamber. This evaluation period also allowed the church a welcome respite from excessive cash outlays and to consider, for the first time, comprehensively restoring its fine but long-suffering pipe organ.

Several things soon became apparent. First, the 1933 relocation from St. Paul’s Lutheran in nearby Richmond—carried out by “two farmers and a mechanic,” according to local tradition—had begun the instrument’s woes. The movers had clearly been competent general craftsmen, but they appear not to have been trained organbuilders. Second, the masonry chamber within which some two-thirds of the organ resided was not well sealed, leaking cold air in winter and hot air in summer, along with the odd bit of blown snow and rain. Third, although the chamber tone opening was more than ample and allowed good tonal egress, the chamber itself was almost too small for the organ it enclosed. The pedal chests had been wedged in at contrary angles, with key action run cross-lots and cobbled together from an assortment of wood tracker stock and soft copper wire. Fourth, the movers had provided absolutely no tuning or maintenance access. To carry out such basic operations as adjusting key action nuts required removal of most of the pedal pipes; to tune the Oboe necessitated either the removal of façade pipes or a precarious climb high above the pedal division.

During this year-long interim, Zion’s organ committee wrestled with a number of options and contending opinions from parishioners, some of whom felt strongly that it was time to “stop pouring money down a black hole, discard the old Möller, and replace it with an ‘up-to-date’ electronic.” While congregational sentiment ran generally against this course, especially among clergy and musicians, many felt rebuilding the Möller or selling it outright would make the most sense. Others in this 190-year-old church advocated a comprehensive restoration, emphasizing the organ’s history, accumulated stewardship, and importance to the fine music program for which Zion’s was known. The church solicited bids for all options, each of which was studied and debated in detail.

Following a vote by the entire church membership, M.P. Rathke, Inc. was awarded the contract for a full and strict mechanical restoration of the Möller. The organ committee chair later explained that we had tendered the winning bid in large part because it was also the low bid, the cost of comprehensively restoring the Möller being significantly less even than a modest electronic to replace it. (The previous sentence is worth re-reading for anyone fortunate enough to possess a historic instrument from any builder.)

During the course of restoration the organ was dismantled in its entirety. Pipework, which upon initial inspection had appeared clean and in relatively good condition, was stored in the church fellowship hall; everything else was taken to our workshop for cleaning, refurbishment, and repair. While in-shop work was proceeding, parishioners were busy tuckpointing, insulating, sealing, caulking, and painting the organ chamber. They also removed carpet from the choir area in front of the organ, sanded and refinished the yellow pine floor below, and invested in a simple humidification unit, built into the existing forced-air HVAC system.

Physical repairs, reinforcement, and reconstruction 

The mechanical restoration was labor-intensive but relatively straightforward. We discovered that sponsil failure had been caused not only by the common condition of overheated, dry winter air, but also by sagging at midpoint of both manual windchests owing to glueline creep. Grid sponsils had thus opened on their undersides like the folds of an accordion in response to 115 years of gravity. After patching and regluing the sponsils, we provided reinforcement to the grid rails of both manual chests to prevent future deflection and to ensure that sponsil repairs would remain permanent. Keyboards were cleaned, flattened, polished, and rebushed; key tails were refelted and releathered. The Swell to Great coupler was comprehensively refurbished. Drawknobs were cleaned and relacquered, stop jambs were rebushed, and a purpose-made rotary blower switch (replacing a massive and unsightly industrial knife switch) was manufactured and applied to the old Bellows Signal stopknob. Kristen Farmer of Winston-Salem, North Carolina, was engaged to strip the many layers of flat black paint that had been applied to the nameboard and to carry out a painstaking restoration of the original silver-leaf stenciling (Photo 1). Five components required remanufacturing, either in full or in part:

1. Double-rise reservoir—It is clear that the organ’s original 5′ x 8′ double-rise reservoir survived the 1933 move to Zion’s along with the rest of the instrument. But in the early 1960s the old reservoir was cut into pieces and replaced by a pair of small and inadequate supply house units, likely because of the difficulty of carrying out proper releathering within the extremely tight confines of the chamber. Most of the old reservoir was discarded at that time, but a few pieces were reused as walkboards, bracing, and a jury-rigged post shoring up one corner of the organ’s framework (ironically, replacing a structural post that had been hacked away to gain demolition access to the old reservoir).

Replicating the reservoir turned out to be less difficult than envisioned, for enough fragments remained that we were able to determine all dimensions and relevant construction details. After developing a working design, we entrusted the actual fabrication to
J. Zamberlan & Co. of Wintersville, Ohio (Photo 2). I first met Joe Zamberlan in 1989 during our respective apprenticeships with Fisk and Noack; our similar training and philosophies have since led to collaborations on a number of projects, Zion’s being but the most recent.

2. Pedal key action—When the Möller was built for St. Paul’s Lutheran in 1897, its internal layout was fairly typical: the Swell stood directly behind the Great at impost level, with pedal chests located near floor level, one on the CC side and the other on the ## side (Sketch A, p. 28). At Zion’s, however, this configuration was impossible owing to the absence of space on the ## side. The 1933 movers thus placed all pedal resources on the CC side, where an L-shaped chamber configuration afforded almost enough room.

However, the Zion’s chamber also required the Pedal chests to be located farther toward the back wall (away from the player) than at St. Paul’s. The original action had employed a unique rollerboard, with cranked arms below the pedalboard and rollers running straight back from the keydesk; trackers had then continued at right angles to the Pedal chests. With the chests forced rearward, the 1933 movers chose not the preferable solution of extending the rollerboard and maintaining the original geometry, but rather the Rube Goldberg solution of chiseling away part of the chamber wall and running trackers at a 45-degree angle (Sketch B, p. 28). This somewhat counter-intuitive approach did get the job done, more or less, but it also reduced tracker motion by nearly 50% and imposed undesirable friction and lateral stresses on the Pedal action. We constructed a new rollerboard—essentially a “stretched” replica of the original (Photo 3) utilizing every scrap of old material we could salvage—and installed it in a manner consistent with Möller’s 1897 design (Sketch C, p. 28.)

3. Pedal winding and stop action— The asymmetrical chamber at Zion’s prompted the 1933 movers to choose yet another unusual solution. Because the Bourdon 16′ chest was slightly too long to fit the available space, it was jammed in askew; the slightly shorter Flute 8′ chest fit alongside with no difficulty. Both pedal chests were then served by the same key action run, but winding was less straightforward because each chest employed ventil rather than slider stop action. Thus two wind ducts were required, but only the 16′ Bourdon chest could be winded easily. Undaunted, the movers ran a second galvanized duct straight through the Bourdon chest rollerboard (!), cut a rough hole in the 8′ Flute chest bung board, inserted the duct, puttied it in place, and then located stop action ventils as best they could. Among other drawbacks, this clumsy arrangement made impossible the removal of the Flute chest bung board for maintenance. (Photo 4) The 2013 solution entailed attaching both stop-action ventils to the reservoir (their original location), constructing new poplar wind ducts to match remnants of the originals, and installing in a manner consistent with other Möllers of the period. (Photo 5)

4. Floor frame and building frame replication—During the 1960s, the Möller underwent a rough removal of portions of its floor and building frames to facilitate demolition of its original double-rise reservoir. Instead of reinstalling the load-bearing post, beam, and floor frame, workers simply nailed up scabs of material left over from the old reservoir, which at best provided crude and insufficient support. (Photo 6) We manufactured and installed replicas of the original floor frame and building frame, taking care to match wood species and copy joinery techniques from the rest of the instrument. 

5. Replica reservoir placement and Great wind duct re-routing—During its time at Zion’s, the Möller’s supreme drawback had been a lack of maintenance access. The general culprit was a narrow (8′2′′) chamber opening, compared with the width of the organ’s main internal structure (8′0′′), but specific obstacles included the location and orientation of both the original double-rise reservoir and the Great wind duct.

The 2013 solution was twofold. First, we turned the new reservoir 90 degrees from its original orientation, which allowed us to respect the essential layout of the original wind system while simultaneously opening a clear access path into the organ. (Sketch C) The end-on positioning of the new bellows will also make possible its easy removal for future releathering, as opposed to the crosswise orientation of the original, whose zero-clearance installation in 1933 surely contributed to its eventual demise.

The Great wind duct posed a more perplexing challenge. The original duct was intact in 2012; unfortunately, it completely blocked the only possible service access into the organ. The revised duct now exits the reservoir, crosses under the maintenance walkway, rises vertically, crosses back over the walkway, and finally makes a 90-degree turn forward to enter the Great pallet box. Although the new duct’s construction is somewhat complex, every effort was made to replicate winding characteristics of the original: routing was kept as direct as possible, and cross-sections were deliberately made slightly oversize to compensate both for increased duct length (an additional 19′′) and for necessary additional twists and turns.

Tonal restoration

Successful restorative voicing depends on a number of factors including sufficient intact material, the restorer’s familiarity with other instruments of the school and period, a cautious and deliberate approach, and especially an agenda-free willingness to allow pipes to tell the voicer what they want to do rather than vice versa. In the following paragraphs we will describe the Möller’s altered tonal state in 2012, outline its evaluation, and summarize how we undertook to reconstruct the 1897 sound.

In 1986, Möller Opus 188 still possessed many of the sonorities that inspired worshipers almost a century prior. By 2012, some beautiful sounds remained, although in greatly attenuated form. The exact cause and timing are difficult to pinpoint, in part because church records from the period are sketchy, but also because of the involvement of so many different technicians, some of whom attempted experimental voicing in a manner both curiously random and spectacularly unsuccessful. The physical evidence furnished by the pipes themselves in 2012 seems the most reliable record and will be related here.

All wood pipes were in essentially original condition, requiring little apart from minor regulation and physical repair. The organ’s sole reed stop—a sweet and assertive Oboe and Bassoon 8′—was likewise in decent physical shape apart from some badly torn tuning scrolls. It had undergone tonal work in 1970 by a local technician who, incredibly, chose to sign each C resonator in block capital letters incised with an awl. Fortunately, his voicing efforts were limited to lightly kinking and roughly cross-filing numerous tongues, both of which steps were reversed in 2013. The entire organ had unfortunately been repitched in 2000 to A-440, predictably choking off many reeds; restoring the original pitch of A-435 helped greatly in recovering the Oboe’s stability, promptness, and robustness of tone.

The metal fluework was a mixed bag. On the plus side, almost all interior pipework was physically intact, if not tonally unaltered. Pipes that were slotted in 1897 happily remained so; pipes originally cone-tuned had been fitted with sleeves but fortunately left close to their natural speaking lengths, so the net tonal effect was negligible. Numerous feet had collapsed from years of heavy-handed cone tuning and the use of thin foot material in the first place; we repaired this damage as a matter of course.

On the minus side, many inside pipes had been randomly altered by a variety of bizarre procedures. About a dozen lower lips had been pinched tight against the languids to where only the original coarse nicking allowed wind through the flue; these pipes murmured more than spoke. (This curious method was limited primarily to the Quintadena bass of the 8′ Aeoline.) A distressing number of windways had been aggressively filed open, removing significant material from both languid and lower lip. Upper lips of many mid-range principals had been torn and distorted; some appeared to have been gnawed by rats. Most front pipes, recipients in 2000 of a fresh coat of gold paint, barely spoke in 2012. While the paint job itself was competently executed from a cosmetic standpoint, obvious pre-existing damage had been simply painted over. Examples included out-of-round pipe bodies, dents, missing or broken tuning scrolls, collapsed lead toes, broken ears, and hooks held on by little more than a vestige of solder. Most front pipe windways had also received a generous infusion of paint (!), completely clogging the original nicking and materially reducing flueway cross-sections. Many dangled from their hooks, with wind leaking audibly at collapsed toes; this latter defect became evident only after the friction tape applied in 2000 as a band-aid repair dried out and began to unravel. Zinc conveyancing from the Great windchest was damaged or missing in many instances, causing weak or dead notes; a smooth dynamic transition between façade pipes and their interior continuations (Great Open Diapason, Dulciana, Octave) was nonexistent.

At this point we faced a critical dilemma. On one hand, we had been hired only to restore the Möller mechanically and to perform minor pipe repairs. Wholesale restorative voicing and major pipe repairs were neither contemplated nor included in the contract price. On the other hand, some pipe damage and tonal alterations became clear only after the restored action and wind system allowed pipes to be heard under full wind and precise control. We faced an uncomfortable choice between simply fulfilling the terms of our contract—delivering a perfectly functioning but poor sounding instrument—or moving ahead with necessary tonal work for which we could never be fully compensated. We ultimately chose the latter, not because it was a sound business decision—it was in fact a terrible business decision—but because of the virtual certainty that, if we didn’t, no one ever would. Then this fine and rare pipe organ, mechanically sound but tonally compromised, would likely be discarded eventually. (It is axiomatic that tonally ugly instruments are seldom preserved, no matter how well they function.) In the end, we simply couldn’t bear the thought. And so we prayed, put our noses to the grindstone, and forged ahead.

We tackled the façade first, essentially moving our pipe shop into the Zion’s sanctuary for a full month. Most of the 33 large speaking front pipes required rounding up on large mandrels, as well as removal of visible dents. Components such as ears whose proper reattachment would have involved soldering—impossible without scorching the gold lacquer —were repaired using clear epoxy. The most difficult operation was removing the enormous amount of paint that in 2000 had been sprayed down into the windways, filling in nicking and coating languids and lower lips with an unwelcome layer of crud. Our front pipe work was accompanied at all times by moderate sweat and considerable sotto voce profanity.

Inside pipes were in some ways easier because they were smaller, but there were also many more of them. A few had to be completely remade; a hundred or so more received careful corrective voicing to match their untouched neighbors; a few hundred more required little apart from cleaning, re-prepping, and normal regulation for tone, power, and speech. The final result is as much a testimony to Möller’s original pipemaking and voicing as to our care in resurrecting them.

Have the results repaid our efforts? On the one hand, it is not too much to say that Möller Opus 188 is once again mechanically reliable and tonally impressive, with a richness and versatility that compare favorably with the best of New England work from the period. As restorers, we are exceptionally proud of this magnificent pipe organ we have labored to bring back to life. On the other hand, ours is admittedly the pride of parents, or at least foster parents, and thus similarly subjective. The final assessment must rest with history, which will be informed by countless organists who have yet to experience this remarkable and historic instrument. We therefore encourage all interested readers to visit Zion’s Lutheran Church, to play and listen, and to decide for themselves. Especially we invite you to share with us your reactions and impressions.

From the organbuilder

While our firm has been very prolific as a builder of new instruments since our founding in 1973, our company also has been very significant as a rebuilder and maintenance firm. So in 2011, when our firm was invited to Tallowood Baptist Church in Houston, Texas, we approached a situation that required all of our skill sets.

A four-manual, 84-rank instrument by another firm had been contracted years earlier and was installed in their new sanctuary between 2008 and 2011. The church was having numerous concerns about the organ after it had been installed. There were mechanical and performance issues, but even more than this, the organ simply did not support their worship. 

Under the direction of the Reverend Carlos Ichter, minister of music, a number of pipe organ builders and consultants were invited to provide an assessment of the organ. The “solutions” given by others ranged from accepting it as it was and trying to increase wind pressure to completely starting over. With the considerable cost, this was not a consideration the church could contemplate, and accepting it as it was would not be an option.

We were asked if we could look at the organ to determine if we could find a way to make the organ a success and what it would require. As we studied the organ and researched the church records, we found numerous contracts, changes, and alterations that had occurred in the design of the instrument from its inception up to when it was installed. Without belaboring the point, this told an interesting story and explained the footing the church took with negotiations going forward, where they had to question everything that they were told.

We started our formal study of the instrument by bringing a team of eight of our staff to the church for one week. We studied the stoplist and scaling of the organ, the chest actions, the winding system, the expression shades, the organ console, the electrical system and relays, and the organ chassis as a whole. We dissected the internal workings of the organ and to better know the pipework, took the time to tune the organ. Next, we voiced some samples of the existing pipework to explore the latitude available for change.

The placement of the organ was in organ chambers in the front of the chancel behind a façade of 32′ pipes, and in a rear antiphonal. The chancel organ chambers sit high in the sanctuary with relatively small tone openings. Portions of these chambers have significant tone traps. The layout and placement of the pipework and chassis acted as physical barriers to the tonal egress of other stops in the organ. There were multiple instances of bass pipes being placed directly in the front of the chambers and covering the tone openings to a very large degree. 

We started our tonal design with a needs study and development of a clearly written, cogent plan for the musical support role of the organ in the church. Our work was to be a change agent to the development of an eclectic instrument that could take part in all forms of music including choral and congregational accompaniment, its role with orchestra, and service playing.

Much of the flue pipework in the organ was of decent quality and well built. However, the organ had a number of individual symphonic, orchestral-oriented stops—which, while beautiful, had been allowed more influence on the overall specification at the expense of a solid foundational accompaniment core. We felt that through reallocation of the flue resources we could accomplish the artistic considerations of a revised specification, while preserving many of the resources in a fiscally conservative manner. 

To begin our work, the pipework and console were removed to our workshop to be refurbished for the new specification. We remanufactured the drawknob jambs to include an entirely new string organ, replaced all of the drawknobs and engraving, replaced the tablet rail, and relocated the combination control panel to a central location so it could easily be seen by the organist. We also made changes to the console expression shoes and pedalboard to conform to AGO specifications, rewired the piston sequencer to function in a conventional manner, and added several pistons to the organ for performance features.

The specification contained a large number of slotted stops, including strings, harmonic pipes, and mixture compositions. The slotting exacerbated the fifth at the expense of the unison pitch and became unstable at a pressure that the pipe mouth cutups couldn’t handle. This third harmonic of the series was pervasive in all of the larger massed flue choruses. Through additions, stop exchange, reallocation of pipework, re-pitching and revoicing, we were able to reinforce the unison registers and improve treble ascendency.

The organ as it had been conceived included a partially enclosed Great. This had placed the flutes and reed of the Great division in the rearmost location of the entire organ where the dynamics were diminutive at best. We decided to abandon this location for a chamber next to the Swell and Great divisions that could speak directly into the sanctuary. This new unenclosed Great location allowed the diapason, flutes, and reed to speak unimpeded into the 2,200-seat room. This projected their full color and harmonics without a loss of dynamics. In the rightmost chamber location, we added to the independent resources of the Pedal division and extended the compass of two Pedal registers, so they could be drawn into the Great as secondary manual registers, balancing out the 8′ fundamental tone from both sides of the chancel.

Many of the strings throughout the organ were orchestral in nature, and small scaled. These thin string stops did not support choral and congregational accompaniment or blend well with the principal and flute chorus fonds. In our design, we decided to gather these romantic resources into an enclosed string division with the inclusion of an 8′ Tibia and 8′ Vox Humana. The movement of these stops from the Great, Swell, and Choir allowed room to add larger divisional strings and additional foundational flue resources. 

The Antiphonal division was enlarged with an independent 8′ Rohrflute. Included with this division are 16′, 8′, 8′ registers to the pedal. The result proved very useful for providing reinforcement and sculpture to the chancel Pedal in the room acoustics.

The organ reeds were generally of a darker color. Some of the organ reeds had been designed for another instrument and had been repurposed and modified for this organ. In addition to the sound of the organ reeds, which was not conducive to our tonal vision, there were a number of loose shallots, and tongue and wedge issues, and tongues that created voicing and tuning problems. Due to differing wind pressures, it was not possible to consider moving reed stops from division to division in support of the revised specification. At the completion of our work, all of the reeds had been rebuilt or replaced. 

The largest solo reed in this organ is the 8′ Tuba Mirabilis. Built of copper and installed as an “en Chamade,” it had been on 24′′ wind pressure, which was too commanding for the sanctuary. It was re-tongued and revoiced on 19′′ wind pressure. Even revoiced, the horizontal focus leaves it as a commanding reed but with greater blending use. We added an 8′ Tromba Heroique stop to the Solo division as a scalable dynamic registration option. With the Solo expression box open it can be a commanding solo stop, but closed can be used as a large ensemble chorus reed.

The Pedal did not have the gravitas that was required of it. The 32′, 16′ Violone unit and 16′ Principal in the façade were revoiced to better fit the room. The 16′ Major Bourdon was rescaled with higher arched cut-ups added to allow more foundational weight. In the Pedal, we added several additional 16′ registers, additional 8′ stops, and a large mixture. In the case of the 32′ reed registers, they had subdued speech and colors that were not cohesive with the final specification as we envisioned it. This became a moot point, as there was no room to relocate these stops. We replaced these extensions with digital voices, which, in this instance, was a better tonal choice. 

The internal layout of the pipework, windchests, winding system, expression shades, and chassis blocked sound. Additionally, there were portions of the organ where access for tuning and maintenance was very difficult. We found places in the organ where some individual pipes had been offset and other places where notes had been silenced rather than attempt repairs on individual chest actions. In conjunction with the redesigned specification we addressed serviceability, winding, and tonal egress.

The windchests were built with a proprietary form of electro-mechanical action in conjunction with an internally developed individual electro-pneumatic action. The reason for the blended actions seems to have been the very high wind pressures employed. The measured wind pressures on the organ ranged from 6¼′′ up to a high of 28′′. This is a realm where electro-mechanical action has rarely been used, with typical wind pressures between 3′′–5′′ being the historic norm for most instruments with this type of chest action. Unfortunately, the individual electro-pneumatic actions had very little travel and constricted the flow of wind into the pipe toes. The result was that a large number of bass pipes were starved of wind. As part of a test we stripped off the rubber cloth pouch on one of the actions and rebuilt it to allow greater depth of travel. The result of this test was immediate and noticeable. These valves were removed from the organ and rebuilt for a large number of the bass registers in the organ, including the 32′ Violone and the core 16′ and 8′ foundational registers. 

In our negotiations with the church the façade pipes and its structure were a specific exclusion. The pipes of the façade are from the 32′ Violone, 16′ Principal, and the 8′ Second Open Diapason, as well as a large number of dummy pipes. Our intent was to voice the pipes of the façade, not taking liability for their construction or racking. As the church had reasoned and we had concurred, it was brand new and should not have been an issue. This supposition changed when several pipes of the (horizontal) 8′ Tuba Mirabilis had hooks that had separated and the racking for these pipes had deflected downward. This set of pipes was in the façade hanging directly over the choir members’ heads and became a looming concern. The church asked us to scaffold up the front of the church and survey the condition of the entire façade and its racking. We found a number of problems that had the potential to be safety issues. Over a period of two weeks we scaffolded the front of the church, secured the toeboards, added vertical structure, installed custom steel supports, added secondary hooks on a number of pipes, and properly secured the pipe racks to the structure. 

The original horizontal expression shades were made with edges over half the thickness of the non-beveled part of the expression shades and opened toward the ceiling. This directed sound into tone traps and away from the choir and congregation. These shades had 4′′ of felt on the front and rear beveled surfaces for a total of 8′ of absorptive felt. The tonal result was a shade opening that acted nearly half-closed even when the shades were wide open. In addition to occlusion, the open shades presented a felted wall to the enclosed division and provided absorption for the non-enclosed stops in front of the shades. We replaced all of the expression shades in the chancel divisions. This allowed one-third more opening to the enclosed divisions and reduced the sound absorption of the open shades to a negligible factor.

To generate the high wind pressures called for in the original organ design, there were a large number of blowers feeding into each other to raise the wind pressures. This created internal turbulence, noise, and heat, as well as noticeable flutter in some of the reservoir tops. The leather on the reservoirs was not well adhered and was beginning to separate from the reservoir wood shells. We knew that for the organ to be successful, we would need to redesign the winding system. This was not a small consideration. In the end all of the reservoirs were rebuilt or replaced with new. We were able to reduce the total number of reservoirs from 49 to 31, and reduce the number of blowers from nine to five, total. We also replaced twelve tremolos.

Our full team of pipe voicers were brought to Tallowood where we located a voicing machine and several workbenches outside of the organ chambers in a stairwell. The voicing of this organ was a marathon of setting pipe samples in the chambers and then removing the pipes so that the large degree of work could be performed outside of the chamber. These pipes were then handed back into the organ chambers and tonally finished. In an instrument on multiple levels with eight separate chamber locations and 94 ranks that included 5,598 speaking pipes, this was no small undertaking. We were able to process the pipework in a seamless fashion, trading off table work with in-chamber finishing. Even with these efficiencies, this process still took months of work. We brought up the organ by division and encouraged the church to begin using it in worship services after approximately half of the instrument was completed. Attending services and rehearsals became a way to gauge and focus our efforts. It was exciting for our firm and for the church, as each week there were additional resources made available to be heard for the first time. In a final review of the project, there were numerous changes that we made to the instrument. My notes show 168 separate items, all of which had subsets. I was asked at one point about one of the smaller changes we were making. The question was, “how important will that one change be?” I answered that one change may in and of itself be small in stature; however, the multiplicity of small changes would couple to become a great change. In the end, the choices we made allowed for a successful outcome, where others had not seen this route to success—at least not at a reasonable cost given the degree of change required. A measure of this success, at the end of this project, was that the church’s faith had been restored in pipe organ builders. We would like to thank the congregation and leadership of the church for the faith that they personally placed in us. I also would be remiss if I did not take a moment to thank our staff for their dedicated efforts.

Artistic and Tonal Direction

A. E. Schlueter Pipe Organ Company

 

From the minister of music

The journey to the completion of our pipe organ was not an easy one. When we came to the full realization that our original instrument was riddled with problems, we sought the council of numerous organists and organ builders in order to find a viable solution. The A.E. Schlueter Pipe Organ Company offered us the most attractive option for completion of our instrument. We spent nearly three years addressing numerous concerns, including listening to disenchanted church members and allowing for difficult conversations in committee meetings. Ultimately, the church approved the proposal from Schlueter, and we now have a beautiful, completed instrument. We are grateful for the Schlueter team and the Tallowood members for the completion of this magnificent instrument for the glory of God.

The genealogy of a restored instrument

Andrew Forrest

Andrew Forrest began with Orgues Létourneau Limitée in February 1999 and in his current position as Artistic Director, oversees all of the company’s projects. He travels regularly to meet with clients, architects, and acousticians, as well as to supervise the company’s on-site tonal finishing. Mr. Forrest has a keen interest in the art of pipe scaling and has completed studies of the String division of Philadelphia’s Wanamaker Organ and the 1955 Aeolian-Skinner pipe organ at Winthrop University among others. He served on the local organizing committee for the joint AIO-ISO 2010 convention held in Montréal, and in October 2011, Forrest was elected to the American Institute of Organbuilders’ Board of Directors for a three-year term. He holds a bachelor of arts degree in political science and economics from Carleton University in Ottawa, Ontario. An organist himself, Andrew Forrest has two children and lives in Mont-Saint-Hilaire, Québec.

The present pipe organ at St. James United Church is unique among Montréal’s many interesting organs because much of the organ’s pipework dates back to an 1889 instrument by E.D. Wadsworth & Brothers, Organ Builders. Edward Wadsworth opened his own organbuilding company in Manchester, England, in 1861 after apprenticing with Kirtland & Jardine; his family subsequently continued in the organbuilding trade under various forms of the Wadsworth name until 1946, when the company was absorbed by Jardine & Company of Manchester. Present-day British organbuilding colleagues have suggested that earlier Wadsworth organs with mechanical actions are superior to the later pneumatic examples, but it remains clear that the Wadsworth name never achieved the status of other British builders during the latter half of the 19th century, such as William Hill, “Father” Henry Willis, or T.C. Lewis.

Perhaps sensing new business opportunities, Edward Wadsworth moved to Montréal in 1887 to establish a branch office of the family company at 298 Craig Street (which today is called rue St-Antoine). The company built two instruments in Canada, the first being a small tracker organ of ten stops for Trivett Memorial Church in Exeter, Ontario, in 1888. The second project for St. James Methodist Church (as the church was originally known) was on a grander scale; the handwritten contract dated June of 1888 was for a grand pipe organ of 49 stops with “tractile” key action. The price for the new organ was established at $11,550, less $2,375 for the church’s old pipe organ. For reference, the signing of the Wadsworth contract took place at the same time as construction was ongoing in the workshops of Samuel and Claver Casavant of a 73-stop instrument for Montréal’s Basilique Notre-Dame; the price for the Casavant organ was some $24,800.

With a 32′ flue stop in the pedal division and two divisions on each of the three manuals, the Wadsworth organ was a novel and complex instrument. The two divisions per manual could be played separately, or coupled together by the touch of a thumb piston under each manual. In addition, each manual had its own drawknobs for appropriate pedal stops and a dedicated “pedalier” thumb piston to bring the selected registration into play as one moved from manual to manual. The middle manual controlled the Great and Back Great divisions, while the Solo—in its own swell box—was partnered on the lowest manual with the unenclosed Choir. The Swell and Echo divisions, playable from the third manual, were enclosed together.

A comparison of the 1888 contract to the instrument’s final specification shows that two optional stops—a 16′ Lieblich Gedackt for the Choir and a 16′ Contra Fagotto for the Solo—were added as the organ was being built. Stops were equally rearranged within the specification, presumably for a better musical result: The 16′ Contra Fagotto was moved to the Back Great division with the Great 8′ and 4′ reeds, permitting the reeds to be brought in or retired collectively in a ventil-like fashion via the thumb pistons under the Great manual. The 8′ Vox Humana likewise migrated from the Solo division to the Echo, while the 8′ Gamba and 8′ Voix Celeste stops came together in the Solo from their separated locations in the Swell and Echo divisions respectively.

Lynnwood Farnam served as organist for St. James Methodist Church from 1904 to 1905, and was well acquainted with the Wadsworth instrument. His notebook entry on the organ provides many details on the as-built stoplist and forms the basis for our understanding of the completed 1889–91 Wadsworth instrument. Though Farnham’s pages on the St. James organ are typically meticulous, it is unclear what kind of key action or key actions Wadsworth employed in his instrument; but it seems highly unlikely that the organ had purely mechanical key action. At the least, some form of pneumatic action would have been employed to manage the complexity of two divisions per manual. Farnam does list all couplers as operating pneumatically, with the console having the six usual unison couplers along with sub and octave couplers for the Swell manual, and a Swell to Great Sub coupler.

Unfortunately, the luster literally wore off the Wadsworth instrument at St. James Church within two years of its completion in 1889. The new organ was frequently crippled by problems arising from humidity and heating within the new church building. The church acknowledged this in an indenture document signed with Wadsworth in June  1891, wherein the complaint was also lodged that the organ’s “exterior has not preserved its absolutely fresh appearance.” The agreement offered Wadsworth an additional $1,000 to repair and otherwise complete his instrument, which, according to the document, had already been in place for two years.

The results of this remedial work were proclaimed satisfactory in a letter dated September 23, 1891, from the agreed-upon arbiter, Frederick Archer, to John Torrance, Secretary to the Trustees of St. James Methodist Church:

 

My dear Sir,

I have this day examined in detail the organ erected by Mr. E. Wadsworth in St. James Church, Montreal with the following results.

I find the wind supply is now ample for every possible purpose, its transmission to every junction of the instrument with uninterrupted “steadiness”. The wind trunks, sound boards, etc. are perfectly air tight and the whole of the mechanism is in thoroughly satisfactory condition.

The repairs have been carefully and substantially done in full accordance with the agreement entered into with him in June last, and with ordinary care and attention, the instrument will, to the best of my knowledge and belief, be now found entirely adequate to all legitimate demands made on it.

. . . I am pleased to be able to report so favourably, but as Mr. Wadsworth has evidently done his work of renovation in so conscientious and thorough a manner, it is but one to him that I could bear witness of the fact. 

 

Archer was a renowned English organist and choral conductor living in the United States, with a reputation as an expert on pipe organs that extended as far as Montréal; he played three dedicatory concerts on the Casavant organ at la Basilique Notre-Dame in May of 1891.

If the Wadsworth instrument was indeed playing as early as 1889, this raises questions about how such a large pipe organ was built within a year by an organ builder who had only arrived in Montréal a few years earlier. For example, from where did Wadsworth obtain his pipework for the new St. James organ? One distinct possibility is that he purchased pipes from another builder such as S.R. Warren & Sons or from a supply house. Similarly, Wadsworth may have ordered pipes from the family workshops in Manchester, England, and had them shipped to Canada. Having said that, Wadsworth was accused of using old pipework in the new organ for St. James Church, including the Pedal 16′ Trombone and the Echo 8′ Hautbois. Our survey of the organ’s present pipework suggests that some ranks pre-date 1889: the f#19 pipe of the Great 16′ Double Diapason, for example, is clearly scribed “1881”, some seven years before the organ’s contract was signed.

Considering the spatial volume of the sanctuary at St. James’ Church and the organ’s recessed location within the chancel, the scaling of the Wadsworth pipework is surprisingly modest in comparison with the large organs of, say, William Hill. The original Great 8′ Open Diapason approaches the Normalmensur (NM) standard around 4′ C and again in the 1′ octave but never exceeds it. The Great 4′ Principal is consistently two to three pipes smaller than the 8′, and it is only in their uppermost octaves that the Great 22⁄3′ Twelfth (a tapered rank) and 2′ Fifteenth ranks exceed NM. These statements are slightly complicated by Warren’s re-scaling and re-pitching of the original pipework in their later reconstruction, but it remains that the scalings of Wadsworth’s principals and choruses were unexpectedly reticent. The quality of the Wadsworth pipes is unremarkable when compared with the later Warren and Casavant pipes, and while most of Wadsworth’s metal pipes were made from spotted metal, the metal itself is quite thin. The Swell 8′ Viola Ætheria is an extreme example: the spotted metal in the bass octaves is so thin that lifting the pipe carelessly from the top can easily deform the pipe’s body. The effect produced by these moderately scaled pipes sounding on generous wind pressures and having been voiced to fill a large room is one of surprising brilliance and great clarity.

Wadsworth’s wooden stops throughout the organ were unvarying, with stopped bass and tenor octaves that transition to open pipes with inverted mouths at c25, similar to a Melodia. The Solo 8′ Concert Flute and the Choir 8′ Lieblich Flute are traditional in the sense that the open pipe bodies are deeper than they are wide, but the proportions for the Great 8′ and 4′ flutes are notably wide and shallow. The present Choir 8′ Flute Celeste originally served as Wadsworth’s 8′ Echo Flute and also features this type of wide mouth construction. Like the metal pipes, the quality of construction is adequate but unexceptional; the thickness of the wood is consistently thinner than the later Warren pipes, and the quality of the joinery is slightly coarse and uneven.

Though E.D. Wadsworth & Bros. was still advertising in the Montréal area as late as 1902, it is unclear what happened to Edward Wadsworth after the completion of the St. James organ in 1891. Wadsworth did not achieve fame or fortune with the St. James’ organ: within days of Frederick Archer’s note pronouncing the organ complete in September 1891, Wadsworth sent the church trustees a handwritten note requesting an advance of $30 as he found himself “rather short.”

The Wadsworth organ served the church for eighteen years, a period that included Lynnwood Farnam’s tenure as organist. It was replaced in 1909 with a pipe organ by the Warren Church Organ Company, reusing a majority of the Wadsworth pipes, at a cost of $6,000. The Warren Church Organ Company was established in Woodstock, Ontario, in 1907 by Frank, Mansfield, and Russell Warren, and can be considered the last vestige of the once-proud Warren name in Canadian organbuilding.

The Warren organ added a number of new stops and redistributed most of the Wadsworth ranks throughout the instrument. A massively scaled 8′ Open Diapason was added to the Great, displacing Wadsworth’s original to secondary status. The Choir division was enhanced by a new 8′ Cor anglais with free reeds; this stop was likely purchased from a supplier, as its construction details are unlike anything else in the organ. A new Solo division was also provided on some 10′′ of wind and included new Stentorphone, Doppelflöte, German Gamba, and Tuba stops.

It appears Warren provided all-new wind chests rather than reusing the Wadsworth chests; this conclusion is based on Farnam’s description of the operation of the sub octave (G) and octave (A) couplers for the Great division and the general increase in the number of stops per division. The rearranging of the Choir to reside within the same expressive enclosure as the Swell, and likewise the Echo with the Solo, is further confirmation that the 1909 instrument represented substantial change behind the original Wadsworth façade.

The new Warren console of four manuals provided a new level of flexibility for organists, with each piston being adjustable by drawing the desired stop combination and then pulling the piston head out by a fraction of an inch. There were a total of four pistons operating on the entire organ and between three and five pistons operating on each division. The console also featured a pédale à bascule (a balanced pedal) providing a general crescendo and diminuendo effect.

Our examination of the pipework suggests that the pitch of the Wadsworth pipes was sharp of modern concert pitch (A=440Hz). To lower the pitch, Warren moved all of the Wadsworth stops up by one note and provided a new low C pipe for each stop; this served to increase the scale of each stop by one pipe in the process. The Warren company also filled out the gaps in Wadsworth’s numerous short-compass stops, such as the Great 16′ Contra Fagotto, Choir 8′ Clarionet, Echo 8′ Echo Flute, Choir 8′ Dulciana, and the Choir 8′ Voix Celeste.

Warren went beyond re-pitching the organ in some cases and rescaled several ranks, likely to achieve a fuller sound. It is equally possible that Wadsworth himself may have engaged in some re-scaling to suit his purposes, if one allows he recycled older pipework in his 1889 instrument. For instance, the Choir 4′ Flûte Octaviante and Great 4′ Principal ranks both have many pipes marked with three successive pitches, suggesting that the original scale was too small. In the same way, the Swell 8′ Open Diapason and 4′ Octave stops have been rescaled no less than three times by their fourth octave. As with adjusting the scales of various stops, there is no reason to think Warren would have hesitated to increase wind pressures and/or revoice the Wadsworth pipework as needed.

The Warren company was equally revisionist with the organ’s reed stops. The scales for Wadsworth’s original Great reed chorus were surprisingly thin—notably smaller than the Swell chorus—so Warren replaced the Great 8′ Trumpet with a new stop of larger scale. The original 8′ Trumpet was reworked into a 16′ Bassoon for the Swell division, with Warren providing twelve new half-length pipes for the bottom octave. Warren also added eighteen new full-length pipes to complete the missing bass of the Great 16′ Contra Fagotto. In fact, the only Wadsworth reed stops to emerge from the Warren workshops relatively untouched—beyond being shifted up one pipe as part of re-pitching the organ—were the Swell 8′ Cornopean, the Great and Swell 4′ Clarions and possibly the Swell 8′ Vox Humana (which disappeared in 1956). Most of Wadsworth’s color stops were replaced outright, though the 8′ Clarionet was rebuilt with new shallots, blocks, and boots, as well as equipped with new adjustable bells for tonal regulation. The 1889 organ had two oboe stops—the Solo 8′ Orchestral Oboe and the Echo 8′ Hautbois—though Farnam’s notes state that the Orchestral Oboe’s pipes had been “taken out” by the time of his visit. Neither stop survived; the pipes for both the present Swell 8′ Oboe and the Solo 8′ Orchestral Oboe are consistent in terms of construction and materials with Warren’s other work.

Farnam returned to St. James Methodist Church on February 15, 1910, to play the new Warren organ, and his notes again provide useful details about the changes that were wrought. Farnam did not seem entirely pleased with all of the changes made to the instrument, noting that the “32-foot has been quite ruined…” and all of the 2′ stops seemed very “spiky,” especially the 2′ Fifteenth in the Great. He praised the new electric key action, though went on to mention the Swell action was very noisy from inside the instrument.

After nearly thirty years of service from the Warren organ, St. James United Church—note the change in name—signed a contract with Casavant Frères in July 1938 for an organ that reused almost all of the old pipework on new windchests. As stipulated in the purchase agreement, the organ would be installed by December 18, 1938—some five months later—at a cost of $16,000. Wadsworth’s 16′ façade was to be preserved, though Casavant successfully lobbied to have the façade moved two feet towards the nave to accommodate the enlarged instrument. The short amount of time between the contract signing and the project’s anticipated completion may reflect the lingering effects of the Great Depression; it is likewise indicative that Casavant agreed to finance nearly half of the contract amount over a three-year period after the organ had been completed!

Casavant’s Opus 1608 incorporated their state-of-the-art electro-pneumatic windchests with pitman-type stop actions built into the pouchboards for instantaneous registration changes. The compasses of the manual divisions were increased from 61 notes to 68 notes, and the number of pedals increased from 30 to 32 notes. The organ’s wind system was comprehensively redesigned, reusing old wind reservoirs and their cone-valve regulators where practical. A new four-manual console was also provided, incorporating Casavant’s pneumatic combination action and trademark furnishings. Like Warren, Casavant consolidated the instrument’s specification from five manual divisions to four—eliminating the Echo division—and transferred several stops between divisions in the process. The Swell, Choir, and Solo divisions were furnished with independent expressive enclosures, each operated by Casavant’s 8-stage pneumatic motors.

A new Nazard 22⁄3′ made up of stopped pipes was added to the Choir, while a 4′ Violina—made up largely from repurposed pipework—was added to the Solo division. The Pedal division was augmented through new extensions to the existing stops, though the Wadsworth 16′–8′ Violone rank appears to have been entirely replaced in 1938 with new pipes. The original Pedal 16′ Trombone with its wooden shallots was extended downward by twelve full-length pipes to create the 32′ Bombarde stop, with the entire rank sounding on 7′′ wind pressure. The Carillon (or Chimes) tubes were maintained from the 1909 instrument but provided with a new striker rail, and a new 61-note Harp was added. Finally, whatever was left of Wadsworth’s “ruined” 32′ Open Diapason was eliminated, and a new 32′ Acoustic Bass stop was provided with twelve independent pipes sounding at the fifth to create the 32′ effect.

The Wadsworth-Warren instrument would have been a comfortable fit with the tonal inclinations of Stephen Stoot, Casavant’s technical director in 1938. An Englishman, many of Stoot’s instruments drew from this heritage, and in this sense the Wadsworth and Warren materials would not have seemed particularly foreign—though there may have been some disappointment with their quality. As one example, the placement of reed choruses on separate windchests was a trend in English organbuilding during the late Victorian and Edwardian eras, enabling higher wind pressures for the reed stops for a smoother tone. At St. James, the Great and Swell reed choruses were indeed separated in this manner, but the similar wind pressures between flues and reeds ultimately made this something of a hollow gesture.

After 1938, the organ saw a few changes prior to the restoration undertaken in 2011–12. The 8′ Vox Humana in the Swell division was replaced during the mid-1950s with a stopped 22⁄3′ Nazard rank. In the 1980s, the original Great mixtures were replaced with two new stops that were poorly suited to the instrument’s aesthetic. Likewise, the Great and Swell reed choruses were modified to give a brighter tone, with the resonators being cut to length after the original regulating slots had been soldered shut. One other significant change relates to the instrument’s appearance: church photos show a heavy drape hung above and to the sides of the Wadsworth façade, serving to hide the windchests and pipes from the Great and Pedal divisions. This drape was in place until possibly the early 1980s but it is unclear when exactly it disappeared; Philip Crozier, Director of Music at St. James, relates the drape had been removed by the time he was hired in 1986. The drape’s disappearance would have surely had some effect on the sound of the organ, tilting the organ’s tonal balance towards an even more present and brilliant sound—though to what degree can only be guessed.

The restoration work undertaken by Orgues Létourneau Limitée over a twelve-month period included re-leathering all of the electro-pneumatic windchest actions; restoring all of the wind reservoirs and other wind system components; and documenting in detail the instrument’s pipework. Forty ranks from the original Wadsworth instrument have survived, though many ranks have been subsequently rescaled or rearranged as described above.

As part of the restoration effort, two new mixtures were built for the Great division to replace the unsuitable examples added in the 1980s. In the absence of information regarding their original compositions, the new mixtures’ breaks follow English examples contemporary to the Wadsworth instrument, while the scalings follow progressions established by the Great 2′ Fifteenth and the original Swell mixture. The mild Swell mixture (containing a tierce rank) was restored to its original specification, with the two breaks returning to their original places at c25 and f#31. Finally, a new slotted 8′ Vox Humana in the style of Father Willis was developed and installed in the Swell division.

After nearly 75 years of service, the four-manual console was thoroughly rebuilt to discreetly incorporate modern playing conveniences, including multiple memory levels, additional thumb pistons, and a general piston sequencer. The organ’s switching system and wiring—much of it dating back to 1938—was entirely replaced with a new state-of-the-art system. Beyond the Wadsworth pipework from 1889, some of the instrument’s more intriguing tonal features include the full-length 32′ Bombarde, the Solo 8′ Stentorphone with its leathered upper lips, the free-reed 8′ Cor Anglais, and the 61-note Harp stop in the Choir division.

The organ was tonally regulated within the church by a team of Létourneau voicers over the course of several weeks in early 2012. Shortly thereafter, the church’s offices and meeting spaces were heavily damaged in a fire, though the sanctuary and the organ were spared. The restored organ was first heard in concert during the church’s annual noon-hour series throughout the following summer, and as autumn approached, the organ served as the “home” instrument for the annual Orgues et Couleurs festival, with two major solo concerts performed by Johann Vexo and Philip Crozier. Since Mr. Crozier’s appointment as Director of Music, the organ has been heard in a continuous series of summer recitals over the past 26 years, with the single exception being the summer of 2011, when the instrument was being restored in the Létourneau workshops.

An instrument in the English Town Hall tradition, the pipe organ at St. James United Church has played an important role in Montréal’s organ scene and has hosted concerts by renowned organists such as Lynnwood Farnam, Fernando Germani, Raymond Daveluy, André Marchal, Bernard Lagacé, E. Power Biggs, Francis Jackson, and Simon Preston. More recently, the instrument has been heard in performances by Joseph Nolan and Sietze de Vries. All of us at Létourneau Pipe Organs remain honored to have been entrusted with this significant restoration project and are pleased to see this pipe organ reclaiming its rightful place as one of Montréal’s most noteworthy instruments.

John-Paul Buzard Pipe Organ Builders, Champaign, Illinois

Opus 42, St. Bridget Catholic Church, Richmond, Virginia

From the builder

The new organ at St. Bridget Catholic Church in Richmond, Virginia, is the 42nd new organ to come from the workshop of John-Paul Buzard Pipe Organ Builders in Champaign, Illinois. It was completed on October 1, 2013, and inaugurated by Ken Cowan in concert on November 15.

The organ’s visual design was guided by the parish’s desire to reclaim a large stained glass window, which the former organ completely blocked. Pastor Monsignor William Carr, who began his clerical career at St. Bridget as the assistant pastor in the 1970s, remembered the beauty of the occluded window and began discussions with John-Paul Buzard in 2005 about the possibilities. The deteriorating mechanical condition and musical limitations of the previous instrument hastened the desire to proceed. The Great Recession delayed the start of the project until the parish raised all the funds to purchase the organ, as their bishop required. 

The gallery’s floor space is quite limited and the window is large. But, the church’s acoustical volume and musical needs required an instrument of a larger tonal size than that which would have been possible with a traditional design. This required some outside-the-box creative thinking, and resulted in our recommendation that the Great division be suspended over the gallery rail, and that the enclosed divisions be thought of as more a divided Swell than independent Swell and Choir divisions. Area organist Grant Hellmers was invited to consult, and enthusiastically agreed that the design met both musical and architectural requirements. The Great’s profile is kept low in order to keep this portion of the organ below the field of glass. The former heavy wood railing was replaced with a more transparent wrought-iron rail. The two enclosed divisions are located in matching cases on either side of the window. The cases’ designs utilize shapes and details found elsewhere in the Tudor-revival building. The result is that the organ cherishes the window, and the gallery and organ are architecturally integrated into the entire worship space rather than being set apart.

Executive Vice-President and Chief Engineer Charles Eames created an instrument whose physical essence truly flows from the building, therein creating room for a larger instrument than the space would have otherwise held. With the new organ in place, the gallery has an additional 100 square feet of usable floor space for the choir and other musicians, which it did not have previously.

This is indeed a three-manual organ. The three-division design evolved from the original two-manual divided Swell concept. The introduction of the 8′ Claribel Flute into what became a somewhat untraditional Choir division allowed the instrument to take on its three-manual identity. The organ exhibits a far greater variety of tone colors and pitch ranges than is typical of many instruments of its size. And it has the uncanny ability to take on the appropriate tonal characteristics of various historical and national styles to fit the character of the musical composition. All of history informs and directs us in the evolution of our singular “Classically Symphonic” tonal style.

The engineering, mechanical systems, and pipe-making all support the artistic end result. The main manual windchests are all electrically operated slider and pallet chests. The chests for the unit stops have expansion chambers built into the very thick toe-boards, to replicate the winding characteristics of the slider chests. All of the pipes are made of high tin content pipe metal, even in the bass, rather than zinc. The large pipes play promptly without having to use beards. The result is fullness and warmth without any hardness or inelegance of tone quality, all the way to the bottom of the compass.

The church’s acoustics change drastically when the room is filled with people, and the church is nearly full every time the organ is used. Tonal Director Brian Davis ably met the challenges that this condition presents by scaling and voicing the instrument for optimal performance when the room is full. The result is that the organ is never too loud, but it fills the room with sound even when played softly. An entire congregation can be supported in its singing with a single 8′ Diapason; the strings are voluptuous and shimmering; the haunting Flute Cœlestis provides an air of mystery; the Choir reeds provide some of the most beautiful cantabile colors imaginable; the smooth and stately Tuba soars above full organ. Nearly every stop can be used with any other to create a new musical color.

Superior tonal design, sensitive voicing, and painstaking tonal finishing result in the exquisite blend and balance of the individual stops and their choruses, relating to both themselves and to the room. And, as Ken Cowan demonstrated to the delight of his audience, there are many ways that this instrument can render seamless dynamic changes. As is the case with all Buzard organs, symphonic color and romantic warmth never sacrifice sprightly clarity and transparency of tone for rendering polyphonic music. 

The church’s growing music program is under the direction of Allen Bean. The children’s program, which Bean instituted and includes both boy and girl choirs, has performed at the Kennedy Center in Washington, D.C., and Alice Tully Hall in New York City.

As a first-time voicer on any project, let alone one of this size, the installation of the St. Bridget’s organ was an eye-opening experience for me. The tonal design of the instrument was set before I was brought onto the Buzard team, but I had the opportunity to voice several stops under the tutelage of Tonal Director Brian Davis. Because of the acoustical characteristics of the room, the organ had to have plenty of treble ascendancy while still maintaining warm foundations and good blend. Thus, the higher pitches “sang out” a bit in the voicing room, but the effect in the church is a lively sound, not at all top-heavy but not dark or muffled.

The organ proved an overwhelming success—clear choruses and the proximity of the Great case to the seating area mean contrapuntal music can be rendered quite effectively; the variety of reed colors available lend themselves to solo work as well as forming a striking Swell reed chorus; two contrasting strings in separate boxes add variety to the foundations; and the presence of two cornets, one in the Great, enables the organ to reproduce French Classical music particularly well. However, it is equally adept at handling more modern literature and orchestral transcriptions, as was demonstrated by Ken Cowan at the inaugural recital. 

Throughout the process of voicing and tonal finishing, I was struck by how each installed stop expanded the ability of the organ as a vehicle for improvisation and interpretation of literature. The body of music this instrument will render is indeed large, and with that in mind I went back to Richmond at the beginning of November to record enough music to demonstrate some of its capabilities, including pieces by Guilmant, Langlais, de Grigny, and several major Bach works. All came off admirably, a testament to the versatility of the instrument and the integration of colors not usually found on American organs, such as the large Pedal 4′ open flute.

The St. Bridget’s organ represents a tremendous outlay of time, energy, and planning in pursuit of an instrument that will handle repertoire of any period with a clear but rich sound, and one which I hope the congregation will treasure for years to come.

From the director of music

St. Bridget Parish, a Roman Catholic parish of about 7,000 registered members, is among the largest in the Catholic Diocese of Richmond. Established in 1949, with the building completed and consecrated in 1950, the parish has thrived since its inception. 

The church building is Tudor style with Gothic elements. Seating only 500, the church provides five regular Masses every weekend to accommodate parishioners. Four Masses are led by organ and cantor, with assistance from choral ensembles. The Sunday evening Mass is led by piano, guitars, and a contemporary choir.

I became Music Minister at St. Bridget in October 2005. The primary accompanying instruments at that time were a transplanted E. M. Skinner organ, which was ¼-step flat and in need of restoration, and a mid-1920s Steinway M, also in poor condition. The Parish Adult Choir of about 20 singers sang for one Mass on Sunday morning, and the other Masses were led by volunteer cantors.

Since then, the music ministry has grown. The Parish Adult Choir has grown to 35 voices, and choirs for children (absent from the music ministry for more than 30 years) include a Boy Choir of 11 singers, and a Girl Choir of nearly 30 choristers. The Boy and Girl Choirs, using the RSCM Voice for Life Program, have established themselves as important and valued ensembles, and distinguished themselves in performances at the Kennedy Center in Washington, D.C. and Alice Tully Hall in New York City.

As the parish’s music ministry has grown, so has the need for an organ that could accompany an ever increasingly diverse music ministry, in a church whose acoustics change dramatically depending on the number of worshippers in the church.

The installation of our new instrument evolved out of conversation between Monsignor Carr and me in August 2005. The 1920s E. M. Skinner organ that so nobly served this parish since the 1970s, brought here from the now deconsecrated Monumental Church in downtown Richmond, was in need of restoration. Conversation quickly turned to action. Within a few months we had explored restoring and enlarging the Skinner organ, with additions that would give it the flexibility required for our growing program. We also received from John-Paul Buzard a proposal for a new instrument, one that would be tonally designed for our acoustical space, give us the flexibility we need to support choirs, cantors, and congregation, and uncover a great west window that is an architectural feature of the church.

The original design proposed by Mr. Buzard underwent several modifications over the following months. The stoplist was refined, as the organ became slightly smaller in scope than we originally envisioned, yet considerably more flexible. Mechanical components were also addressed in this process (another nod to flexibility), including independent swell shades on two sides of each enclosed division. The design process of this instrument was a delight for me as parish musician. The parish is forever grateful for the work of our Organ Project Consultant, Grant Hellmers, whose wisdom and experience helped define the parish’s needs in an instrument, and brought clarity to the process as St. Bridget personnel and I worked with the Buzard shop in the design phase.

Once the design was finalized, the Buzard shop began to plan the physical design of the instrument, and, under the direction of Tonal Director Brian Davis, began to envision the tonal color of each and every stop in the instrument. Mr. Davis’s ability to take the numbers that represented the (ever-changing) acoustical properties of the church, and to determine scale and timbre of each of more than 2,000 pipes in 38 ranks, producing more than 48 stops, proved to be remarkable. Charles Eames also worked magic, engineering the organ that John-Paul and Brian envisioned to fit into a relatively small space.

Several weeks of voicing accomplished by John-Paul Buzard, Brian Davis, and Jonathan Young brought St. Bridget Parish’s organ to completion. The instrument’s design, its pipes, its mechanicals, the construction of the instrument’s beautiful casework, its installation, its voicing, the work of St. Bridget Church’s own organ project committee, building committee, and staff, altogether required more than 20,000 hours of labor. I believe that even when it was labor bought and paid for, it was a labor of love, and that the Buzard shop always acted with a sense of vocation.

St. Bridget parishioners gave freely of their time to make sure the church was ready to receive the instrument. John McCulla coordinated our efforts with the Buzard shop. Richard Lewis designed the mechanical and electrical components the church provided. Terrence Kerner arranged for the addition of HVAC for the organ gallery. Patrick Ross and the St. Bridget maintenance staff were always on hand to help subcontractors and the Buzard crew with whatever they needed. These parishioners have remained involved even after the organ’s completion to assure the project is truly complete and in keeping with the church’s beautiful architecture.

Several enabling gifts allowed this project to move forward. In all, some 265 parishioners, a relatively small number of our many parishioners, made this instrument a gift to the parish. Additionally, still more parishioners have contributed to the Friends of Music Fund at St. Bridget, to enable an inaugural concert series, so that we can make it a gift to the Richmond community.

Because this platform is here for me to do so, I want to express my special gratitude to our Pastor, Monsignor Carr, who began this conversation more than eight years ago. He envisioned a pipe organ for St. Bridget Parish. He let the donors to the project know of our need. He guided Parish Council, Parish Finance Council, and all who made decisions about the organ throughout the process. And, if there is anyone who delights more in this instrument than I do, it is Monsignor Carr.

Introduction

The modern "orgelbewegung" organ revival has cultivated as a norm the German neo-Baroque organ, using stopped or partly stopped flutes as foundations at 8' and 16' pitch in small instruments. This practice has been given such authority that many organists do not question it; but this type of organ is only one style among many. Neither it nor any other design ought to be raised to the level of dogmatic acceptance. The multiple foundation stops found in the best nineteenth-century organs  represent the continuation of a tradition which had been already established in the Baroque period. A perception of the history of the organ which does not ignore the nineteenth century should lead us to see that multiple foundation stops in the manuals are consistent with eighteenth-century practice and not the exception.

In this paper, the presence of such stops in important examples is noted and described. It is observed that some organs of the eighteenth- and nineteenth-century have an extraordinarily cohesive blend of stops in various combinations. An acoustic theory is put forward to explain the reason for this blend or its absence. This theory states that stops are able to blend when harmonics are present in the unison tone which duplicate the fundamentals of the upper pitches. It is also observed that stopped pipes used as foundations cannot provide these harmonics.

A most important application of this point of view is that the pedal of a small organ may be based upon a 16' open subbass, not the traditional stopped bourdon. Several organs are cited which demonstrate this practice, from the eighteenth, nineteenth, and twentieth centuries. It is noted that in the manual divisions the Italian organs used 8' open pipes as foundations through their entire history; however, the Italian organ has generally been ignored as a model for small instruments. It is concluded that the exclusive use of stopped pipes as fundamentals in small organs should be reconsidered. The extensive use of stopped flutes represents a restricted, national style which ought not assume the role of a universal model. Open pipes blend better and make the tone more cohesive. We should question accepted norms of "organ design" and revise them in favor of those traditions which include the use of open pipes to provide the fundamental tone. This will allow organs in churches to be most effective at their primary role, to provide a foundation for congregational singing.

Historical Background

With the neo-Baroque organ revival, organ scholarship blossomed and has resulted in the construction of new instruments re-creating stop lists that belong to specific national or regional styles of organ building. These instruments reflect earlier times and their respective literatures. These trends were transmitted remarkably quickly to North America. This was accomplished primarily by North American scholars studying abroad and by European specialists teaching in North America. Some years later these same trends appeared in other English-speaking countries such as Australia. This organ revival filled a particularly heartfelt need resulting from a discontinuity of the traditions of organ building which was most evident in the "orchestral" and theatre organs of the 1920s.

It is not a simple matter to establish exactly why traditional concepts of organ building were abandoned, but if any one cause is to singled out, it must be that certain types of electric action made possible the use of the same pipes at two or more pitches (unification) or on two or more keyboards (duplexing)1. These purely technical devices of organ design, made in the interests of a certain type of economy, made it impossible to voice the organ so that its stops could blend. This break with the traditional concepts of organ voicing set the stage for rediscovery of older traditions, rather than allowing a normal evolution of organ design. When it became obvious that something had been lost through neglect, there had to be a "revival" so that whatever it was that had been lost could be reinstated.

Unification and duplexing destroyed the blending ensemble so thoroughly that, despite the effects of the organ revival movement, we have not yet recovered the consciousness that the stops of an organ must truly blend together. The result is a genuine anachronism: the separate stops of many modern organs refuse to blend, while there still exist a few forgotten nineteenth-century instruments, the best from their time, which preserve the ability of every one of their stops to blend with every other. While the "revival" organs do not have unification or duplexing, often they show an indifference to blend that can be traced to the disastrous lapse of sensitivity in voicing that unification and duplexing have left as their aftermath.

New Organs in North American and Australia

One result of the organ revival has been the crystallization of the neo-Baroque stoplist into a norm for the construction of new organs. But because a "revival" resurrects an older stratum of the culture which has already passed away, the organ revival reflects the specific requirements of a style of organ playing which is no longer in an active phase of development. The "revival" organ often reflects the general requirements of eighteenth-century organ playing and the specific demands of German Lutheran organ literature. It is now customarily imposed upon English-speaking regions of the world, regions which possess traditions and literatures vastly different from those of an eighteenth-century culture. This neo-eighteenth-century norm presents itself virtually as a doctrinal system, often assuming a degree of authority that is insisted upon in the same way that a theological principle may be insisted upon.

The North American adoption of the neo-Baroque organ design was a "marriage of convenience" to aid the recovery from the theatre organ debacle and its after-effects. It has persisted quite a bit too long. Now we are being called to take up once again the historical evolution of the instrument.

The objective of the author is to develop a theory of organ registration and specification that does not reflect the demands of any national or regional style. Instead, it is a theory of organ specification which proceeds from an acoustic basis. It is intended to fulfill the needs which we find in English-speaking churches at the end of the twentieth century. Like the ancient eclectic philosopher, we have selected such doctrines as please us from every school. Our music borrows freely from many sources, and is not exclusive to any one tradition.

The Nineteenth-Century Contribution

In Australia, New Zealand, Canada, the United States and Europe, there still exist nineteenth-century organs virtually untouched or relatively intact, preserving a tradition of organ building which has largely been lost in the major population centers. A number of these organs are being rehabilitated and it is no longer fashionable to take away their original characteristics. Restorations, not rebuilds, are becoming more common. An example is the organ formerly of St. Stephen's Roman Catholic Cathedral, Brisbane, built about 1880.2 This old instrument survived the rebuilders because of the happy circumstances of benign neglect. Fortunately, there was not enough money available to replace or "modernize" it.

This organ features tracker action, low wind pressure, bright reeds, and clear but not loud upper work. Everything rests upon a foundation of several unison stops and all reasonable combinations of two or more stops can be depended upon to combine into a blend of great cohesion. These factors suggest that this organ represents an evolution of the traditions of organ building which had been current during the century before. Though the sound is quite different from a Baroque organ, there is no radical departure from the eighteenth-century traditions, but rather a continuity with them. The result is that the music of both Bach and Brahms sounds very comfortable on this instrument.

The Great manual of this organ corresponds almost exactly to the Baroque ideal in the plan of the stops and their assignment at various pitches. The character of the stops has changed according to the styles of the period, but the essential design of the ensemble is preserved. As a model for comparison the specification of the Great manual is given from the Löfsta Bruk organ of 1728 by the Swedish builder Cahman,3

It is apparent from nineteenth-century examples (for instance, by E.&G.G. Hook and others in Canada and the United States), that tracker action, low wind pressure, bright reeds, upper work and mixtures were all elements of organ building that had been carried over into the nineteenth century from the eighteenth century. What about the multiple unison stops? Do these represent a "Romantic" tradition only, or are they an element that was being carried over from the Baroque period into the Romantic era? In both organs cited above, there is an open 8' to serve as the foundation for the ensemble, a wide-scaled flute to give it depth, and a third 8' stop to contribute the harmonics necessary to bind the ensemble together. In the eighteenth century, these harmonics were provided by the Quintadena, meant to act together with the Principal 8'. In the nineteenth century the Diapason had a wider scale than the eighteenth-century Principal. Therefore the third 8' stop, which must contribute the binding harmonics to the ensemble, is the Gamba, a string-toned stop of such wide scale in this organ that it is very much like a narrow-scaled Violin Diapason.

If we emphasize the similarity of the two stop lists rather than their differences, we can obtain a better view looking back at the eighteenth century and also looking forward to the twentieth century. It is possible to theorize on specifications which can accommodate not only the music of Buxtehude and Bach, but also the other portions of the literature, such as that by Dupré or the French symphonists, which have grown out of the traditions of the nineteenth century.

The Difference between "Registration" and "Specification"

Organ specification is not the same thing as organ registration. A specification is a list of the various stops of which a particular instrument is composed. Registration is the setting down of certain combinations of stops in order to produce a desired effect. In a given organ, there is a specification of stops which should combine together to give the instrument a distinctive musical formulation, which we call "ensemble", all the parts of which match together and harmonize. From this specification, an indeterminate number of registrations may be drawn, which express various facets of that distinctive musical ensemble. The full organ registration should be equivalent to the specification of the instrument less certain stops intended for special effects.

The specification of an organ should be built up, not to make combinations, but rather to provide for maximum blending of stops. Blending stops may be pursued in two directions--vertically (8', 4,' 22/3', 2' etc.) and horizontally (8' + 8', 4' + 4'). The 8' and 4' accompaniment stops, which are flutes, should blend horizontally with the principal chorus. How often have students been admonished not to combine stops of the same pitch, because of tuning problems! In nineteenth-century organs, the 4' flute was usually open or harmonic and combined naturally with a 4' principal, rather than beating against it. Both the Brisbane organ and the Löfsta Bruk organ present an open 4' flute capable of combining with a 4' principal. This is not a new characteristic making its first appearance in the nineteenth century.

The reed stops should blend horizontally with both flutes and principals. There ought to be maximum harmonic reinforcement between the reeds and flues--that is, there should be no sour off-harmonics in the reeds. Therefore, full-length reeds are to be preferred to half-length reeds, which have a peculiar harmonic series with flat ninths and so on.

Finally, at least one mixture stop may contain a tierce, in order to assist in the blend with the reeds. This characteristic occurs in both the Brisbane and the Löfsta Bruk organs. We can see from the above, that specification is the organ builder's art. Specifications should not be made up to encompass the most possible registrations. Rather, the various registrations should be derived from each organ's individual specification. The specification of a particular instrument should be set up to secure the maximum possible blend, both in the horizontal and vertical directions. From a specification may be derived two contrasting types of classes of registrations: blending registrations and non-blending registrations. These are defined and discussed below.

The Harmonic Overtones of Open and Stopped Pipes

It is well known that all organ pipes produce composite tones consisting of various harmonic partials.4 The partials of 8' open pipes which concern the present theory of registration are these:

First partial = Fundamental

Second partial = Octave = Fundamental of 4' stops

Third partial = Quint = Fundamental of 22/3' stop

Fourth partial = Double octave = Fundamental of 2' stop

Fifth partial = Tierce = Fundamental of 13/5' stop

The fundamentals of the 4', 22/3', 2' and 13/5' stops all reinforce harmonics already present in tone of the open 8' stops. Therefore the 4', 22/3', 2' or 13/5' stops will blend acoustically with the open 8' stops.

The stopped pipes, in contrast, behave very differently. They emphasize only the odd partials. Those partials of stopped pipes which characterize their tone are these:

First partial = Fundamental

Third partial = Quint = Fundamental of 22/3'stop

Fifth partial = Tierce = Fundamental of 13/5' stop

These stopped pipes form strong blends with mutation stops, but not with the octave-sounding registers of the principal chorus.

"Blending "and "Non-Blending" Registrations

"Blending" registrations are defined here as those registrations which consist of stops arranged in such a manner that the harmonic overtones of the lower stops duplicate the fundamental tones of the higher stops.

Examples:          Open 8' (Principal)        +              open or stopped 4'

                  Open or stopped 8' (Principal or Quintadena)                  +             22/3' Quint

"Non-blending" registrations may be defined as combinations of stops arranged in such a manner that the harmonic overtones of the lower stops do not duplicate the fundamentals of the higher stops.

Examples:          Stopped 8'         +               stopped 2' or open 2'

                  Stopped 8'         +              stopped 4' or open 4'

Blending registrations are used for music which demands the full chorus attribute of the organ. Non-blending registrations should be used where the music is to stress the maximum independence of line, such as in the typical bicinium type of chorale prelude.5

Some compositions may feasibly use either a chorus type of registration or a contrasting non-blending registration which stresses independence of line. Hence the dividing line between the two types is not clear. To express this ambiguity of intention, hybrid registrations are useful. Some of the stops blend with each other, while some do not.

Examples:           Open 8'                +              stopped 4'          +              open 2'

                  Stopped 8'         +              open 4'                 +              open 2'

In the first example, the open 8' combines with both the stopped 4' and open 2,' but the open 2' cannot combine with the stopped 4' because there is no 2' partial in the stopped 4'. In the second example, the stopped 8' can combine with the open 4', but not with the open 2'; also the open 4' and open 2' can combine with each other. For both examples, the character is not clearly either "blending" or "non-blending." Registrations with this property might be best used in music which has three or four voices where both the cohesion of the lines and their independence are to be stressed simultaneously.

These observations lead to the conclusion that successively higher pitches in a registration should be more open acoustically.

Example: Stopped 8' + partially open 4' (Koppelflute or Rohrflute) + open 2.

Single stops can also exhibit this hybrid characteristic. For example, the bottom octave may be stopped, the next octave partially stopped, and the treble fully open.

Composite Solo Registrations

The foundation 8' flutes should contain the 4,' 22/3', 2' and 13/5' partials, so that the mutation stops can join with them acoustically. The 4' flutes should contain prominent quint partials, if there is a Larigot or quint at 11/3' above. A conclusion which follows from this type of design is that the stop which determines the musical quality of a Cornet V is the 8' flute that supports it, rather than the mutations of which the Cornet itself is composed.

Solo registrations involving reed stops may be either blending or non-blending. It is interesting to contrast the combination Oboe 8' + flute 4' with the combination Clarinet 8' + flute 4'. The action of the flute in each case is different. There is, however, a little of every harmonic to be found even in the hollow-sounding reeds such as the Clarinet and the Krummhorn, because the reed itself produces a full series of partials.

If we contrast the registration Oboe 8' + quint 22/3' with Clarinet 8' + quint 22/3' we find that the adhesion of the quint to the Clarinet is stronger than the cohesion of the quint with the Oboe. This happens because the quint harmonic (22/3') is much stronger in the Clarinet than it is in the Oboe. A composite solo registration may be used with either a blending or a non-blending accompaniment registration, depending upon the character of the accompanying voices.

Conclusive Statement of Theory

This present theory of registration is easy to apply. If a stop at a lower pitch contains a harmonic that can bind with the fundamental of a stop at a higher pitch, then those two stops are capable of a good blend. If not, they will be limited in their capability of blending, or prevented from it altogether. An ensemble composed from a "non-blending" specification (such as is found in small neo-Baroque "revival" organs) comes out in layers, rather than producing a blended, cohesive, and "blooming" sound.

Specification of Foundation Stops at 8' and 16' Pitches

A practice which flows from the acoustic analysis of specification is the placement of open and partially stopped flutes at the 8' pitch in the manuals and at the 16' pitch in the pedal organ. This is much in contrast to the idea of placing them exclusively at the 4' pitch and higher in the manuals and only from the 8' pitch upward in the pedal. In the manual divisions, the economy of the organ and the space it requires are not greatly affected, since in most cases the bottom octave of open flutes at the 8' pitch is stopped and made of wood to assure quickness of speech. The provision of a narrow-scale open subbass in the pedal requires room overhead and this stop is expensive; but this expense should be more than offset by the fact that such a pedal division is more versatile and blends so much better than the alternative. The organ can be made a stop or two smaller than might otherwise be planned. The expense of the open 16' stop is more than recovered because a smaller pedal organ will actually sound better and more compelling.

When the pedal is based upon a 16' open flue, producing a relatively quiet tone--about the same intensity as a normally stopped Subbass 16'--there is an exquisite blend of harmonics. The upper partials of the soft open 16' are able to combine with the fundamental tone of the various members of the chorus above, particularly the 8' Principal.

This is the design of the pedal organ specification which is found in the Cahman organ of Löfsta Bruk.

Öppen Subbas 16'

Principal 8'

Gedackt 8'

Kvinta 51/3'

Oktava 4'

Rauschkvint II

Mixtur IV

Basun 16'

Trumpet 8'

Trumpet 4'

It is exceedingly rare. Cahman also did another interesting thing. The combination Gedackt 8' , Quintadena 8' and Quint 22/3' is repeated both in the Great and Positive organs. Are we to realize from this repetition that Cahman provided the Quintadena 8' in each case to secure an acoustical, harmonic "locking in" with the quint 22/3' above it? Most modern specifications would have omitted the Quintadena, probably on both manuals, and supplied a stopped 16' to the pedal, substituting for the Open Subbass 16' a louder Principal 16'. The particular quality which sets this Cahman organ apart as a gem among artistic instruments would be destroyed.

The Open Subbass of the Löfsta Bruk organ is made of wood and has a fairly narrow scale. In the published photographs of the organ, the end of the largest pipe can be seen behind the 8' Prestant of the pedal organ. The lowest pipe is approximately seven inches square. If this principle of specification and voicing is to be retained in an organ large enough to offer both an open and stopped 16' flue in the pedal, it is important that the open stop be of narrow scale and voiced quietly so as to support the chorus above. When 16' open flues are scaled and voiced loudly, so as to "add power", their harmonic development is much reduced and their ability to contribute to a unified chorus ensemble is lost. Therefore the 16' open flue stop should be planned to be no louder than any stopped 16' open flue which may accompany it in the pedal.

An Example of the 16' Open as the Only Pedal Foundation Stop in a Modern Organ

The Casavant organ at the Dordt College chapel at Sioux Center, IA, was built under the supervision of the late Gerhard Brunzema. It is a 37-stop instrument which contains only principals and reeds in the pedal according to this disposition.6

Praestant 16'

Octaaf 8'

Mixtuur VI

Bazuin 32'

Trompet 8'

Cornet 2'

Since there is only one 16' flue stop, this stop also has to be able to fulfill the role normally taken by a stopped 16'. Therefore it must not be loud. But if the 16' foundation cannot be loud, how is power to be built up? The Sioux Center organ relies on its reeds rather than its flue stops for power in the pedal organ. This also happens in the Löfsta Bruk organ.

The Use of Mutation Stops to Support a Pedal 16' Flue Stop

The Löfsta Bruk organ builds power for its 16' flue both through its reeds and through a 51/3' pedal quint. This method of building power and clarity without overvoicing the 16' flue stop was followed regularly by the late Nils Hammarberg, a modern Swedish organbuilder of Göteborg. A stopped 8' pipe acquires definition though the reinforcement of its third partial, the 22/3' Quint. The Quint's fundamental is the same as the third partial. Cahman specified a Quint 51/3' in the pedal organ to complete the same harmonic function that the 22/3' Quint fulfills in the manual divisions. The combination of a soft open 16' together with a quint supporting its third partial gives the pedal organ a firmer foundation than any loud, wide-scaled diapason could ever provide.

The mutation stop must be narrowly scaled and gently voiced, and a true principal rather than a flute. This is also a prominent characteristic of the 22/3' and 2' stops in the Great organ of the nineteenth-century Brisbane instrument in Australia. Blending tone is aided by conservative scaling and gentle voicing, both of the fundamental tone and its corroborating harmonic.

Hammarberg continued this tradition with the provision of a pedal stop called "Aliqvot," a name which simply means "harmonics." It can refer to any useful combination of supporting harmonic partials. In his most recent work it consisted of the following 16' partials:

51/3' quint = third partial

31/5' tierce = fifth partial

22/3' quint = sixth partial

2' fifteenth = eighth partial

Hammarberg developed this idea because in Sweden, organs are placed in the gallery at the western end of the church and there is no headroom for open 16' pipes. It substitutes for the open 16' sound a resultant:

                  Alikvot                  51/3' C                  96 Hz

                  Principal               8' C        64 Hz

                  difference                               32 Hz = 16' C

He also provided the 32' resultant in the same way:

                  Kvinta 102/3' C               48 Hz

                  Principal               16' C     32 Hz

                  difference                               16 Hz = 32' C

Sometimes the Alikvot mixture has less than four ranks and sometimes more; Hammarberg sometimes built it in the following way:

51/3' quint = third partial sounding G

31/5' tierce = fifth partial E

22/7' flat seventh = seventh partial flat A#

17/9' ninth = ninth partial D

A typical specification for such a pedal organ is:

1. Subbas (wood, stopped) 16'

2. Kvinta 102/3'

3. Principalbas 8'

4. Gedacktbas 8'

5. Alikvot 51/3' + 31/5' + 22/3' + 2'

6. Bombard 16'

7. Trumpet 8'

8. Rörskalmeja 4'

9. Koralbas 4'

Hammarberg built this plan in conditions where headroom was restricted, from about 1981, and used the Alikvot mixture as well as the 102/3' plus 16' resultant in various instruments dating from the 1960s and 1970s. Examples of this work may be found in Mora, Boras, Göteborg, Falkenberg and Grebbestad, all in Sweden. In all of these organs, the presence of the Alikvot stop relieves the 16' from any obligation to attempt to produce power through volume, with the attendant deterioration of its tone.

Hammarberg's plan of pedal specification works well with gently voiced open 16' flue pipes, to develop a pedal organ of considerable power, while allowing the open 16' flue to remain as the only 16' flue stop in the division. Hammarberg's ideas combine well with Brunzema's plan (above) to give the following:

1. Subbass 16' wood, open narrow scale, about 7≤ CCC as at Löfsta Bruk

2. Quint 102/3'

3. Principal 8'

4. Gedacktbass 8'

5. Quint 51/3'

6. Coralbass 4'

7. Alikvot, composition as appropriate

8. Basun 16'

9. Trumpet 8'

10. Rohrshalmey 4'

Summary

The modern organ reform movement has given strong support to the exclusive use of gedackts and other stopped pipes at 16' and 8' pitch in small organs. This type of specification is derived from a "Neo-Baroque" Germanic tradition of organ building. Although these stopped pipes sometimes have narrow chimneys as in the Rohrflute, they nevertheless act as stopped pipes in the ensemble. This practice of specification leads to a form of non-blending registrations.

It is curious that the Italian organ, in which one always finds open pipes for foundation tone, is hardly built today, while the typical "reform movement" type of instrument, with a high percentage of stopped pipes, is commonly built. This is not merely a result of economic considerations, but rather a question of style and fashion.

Derived from this background is the practice of specifying a stopped Subbass as the pedal foundation stop. It provides the fundamental pitch in an undefined sound that blends with difficulty; and when pushed to provide greater volume, its tone deteriorates very quickly. A stopped Subbass has little blending power because it has no harmonic at the octave. This defeats the purpose for which it is intended. A 16' pedal stop should do more than supply a fundamental pitch; it should provide a harmonic series to support the chorus above.

We have examined pedal organ designs by builders who have not frozen their thinking into traditionally accepted ideas. The contemporary organs of Brunzema and Hammarberg take much of their design from the organ reform ideals, but also demonstrate innovative ideas which reinforce the true acoustical nature of the instrument. Let us turn to models such as these, rather than the typical "organ reform" prototypes, in order to construct organs of moderate size that do not lose our public for want of a good foundation for singing.

If we emphasize gently voiced open pipes as the natural source of fundamental tone, and obtain the power of the organ by means of harmonic reinforcement, we will assure that its sound has that live-giving warmth which will appeal to the musical public.8

The Löfsta Bruk Organ

by John Hamilton7

The sumptuous Löfsta Bruk organ was built in 1728 by Johan Niclas Cahman, a North German builder who had emigrated to Sweden. Of twenty-eight registers (two manuals, pedal), it was conservatively conceived; it is today Scandinavia's finest example of the sort of instrument known to the Praetorius/Scheidemann/Scheidt/Buxtehude school. The lavishness of conception is indicated in, for instance, the pedal's two full-compass full-length sixteen-foot registers, a Principal and a Posaune--in a church seating barely three hundred. The organ has largely escaped the periodic "modernizations" which have plagued many important old instruments. When nineteenth-century tastes called for a different sort of churchly music-making, the Ryggpositiv windchest and pipes were carefully removed and stored in the church's attic; Romantic tastes were satisfied by the two-manual-and-pedal reed organ which replaced the Ryggpositiv. A restoration in the early 1960s, by a Danish firm, was in the tradition of the best obtaining taste of that decade; it was well carried out but, alas, today's wind-supply is the mercilessly steady nineteenth-century norm, today's temperament is nineteenth-century equal, today's reed tongues are modern (the restorer discarded the old tongues without making measurements or metal analysis), and today's key action possibly is overly spring-loaded. Plans are afoot to correct these modern intrusions.

Tone is big, noble, unforced, in the north European historic tradition. Plenums admirably support the ardent congregational singing known to have characterized the eighteenth century: today's listener readily envisions vigorous hymn singing from strong-lunged Walloon ironwrights, who sat together in the church's most prestigious area. Of particular interest are the organ's mixtures, all of which contain third-sounding pipes contributing strength and color to the plenums. Individual Principal registers are among the most gloriously singing known to this listener.

Today's organists at Löfsta Bruk are Birgitta Olsson, the excellent parish organist, and Göran Blomberg of Uppsala University, who with a background in musicology, organ performance, and classical archaeology, is a strong summer presence. Blomberg's personal involvement with the instrument coincides with the period of its modern international reputation starting around 1980; his tireless, knowledgeable commitment to its becoming known have resulted in the organ's having become widely recognized even earlier than was the village itself. He has recorded an excellent selection of material by Buxtehude and Bach on an LP released by Bluebell-of-Sweden and is preparing digital recordings. Birgitta Olsson and Blomberg have organized a succession of summer "Cahman Days" forming an annual framework for presentation of the instrument; these included an international festival in August 1987, during the Buxtehude anniversary. And Blomberg offers numerous demonstration recitals on the instrument for groups of both lay and professional visitors.
