Orgues Létourneau Opus 136

Orgues Létourneau, St-Hyacinthe, Québec, Canada; Market Square Presbyterian Church, Harrisburg, Pennsylvania

From the builder

Market Square Presbyterian Church has long been a landmark in Pennsylvania’s capital city. The congregation was founded in 1794 and has occupied its current sanctuary since 1860. The church today is simultaneously traditional and modern, with worship services that balance thought-provoking sermons and inspiring music. Market Square Church also puts an emphasis on service, with ministries to support homeless and transient persons in downtown Harrisburg, as well as refugees and immigrants. The congregation is actively involved in a variety of social justice endeavors, supports environmental initiatives, provides hospitality to local groups, and offers a broad embrace to the LGBTQ+ community. It has been our experience that all are admirably welcome at Market Square Church.

Our first of many visits to Market Square Church was at the invitation of the church’s new minister of music, the tireless Tyler Canonico. Our broad mandate was to survey the church’s pipe organ and to present options on what could be done.

M. P. Möller’s Opus 11805 of three manuals and 83 ranks was completed in 1991, incorporating much of the church’s previous Aeolian-Skinner pipe organ from 1947 (Opus 1048). The Aeolian-Skinner had been hidden within chambers, but the Möller displayed zinc and spotted metal façade pipes in a case housing its Grand Orgue division across the back of the loft. A new Positif division was divided between two cases on the gallery rail. The organ additionally had two sizable and independently expressive Récit divisions in opposing chambers; both Récits played awkwardly from the upper manual at the console.

During that first visit, we concluded a top-to-bottom reconstruction of the organ was needed. In addition to desirable tonal improvements, the three-manual console was worn beyond redemption, and the instrument’s switching system was obsolete. The crude casework needed to be replaced with something more appropriate, but more pressing, the two organ chambers’ flimsy hardboard walls and ceilings required substantial improvement.

Our subsequent proposal recommended reusing the Möller and Aeolian-Skinner materials where possible as a measure of good stewardship. This included most of the pipework, the electro-pneumatic windchests, and some wind reservoirs. From a tonal perspective, we wanted to consolidate the instrument within the limits of what the windchests could accommodate. While a new Great and part of the Pedal would reside in a central organ case, the Möller’s Récit divisions could be brought together into a proper Swell in the east chamber. A tertiary Choir division would offer complementary colors in the west chamber, and through refashioning one of the Aeolian-Skinner windchests, a new ten-rank String division could reside under the Choir division. A small Positive division would reuse one of the chests previously on the gallery rail but would sit in front of the Choir behind the loft’s west ceiling grille.

The project we proposed was significant but at no time did we get the sense that our far-reaching ideas were unsettling to the organ study committee. The committee seemed ready for a challenge, as did the broader church in later meetings. Indeed, our discussions about renewing the pipe organ grew into a broader review of the church’s sanctuary and its acoustic, as well as the organ loft and the limitations it presented for the choir. Acoustician Dan Clayton soon joined the team, ensuring the acoustic would be improved for music without harming the spoken word. This global project at Market Square Church was spearheaded by David and Gwen Lehman over a two-year period. Their assiduous work resulted in new hardwood flooring for the sanctuary, comfortable new pews, a reconfigured choir loft, and refurbished organ chambers. Throughout the project, the organ study committee’s and the Lehmans’ efforts were supported time and time again by the church’s director of music emerita, Ellen Hunt, and the church’s senior pastor, the Reverend Tom Sweet.

The Möller pipe organ was removed and packed for shipment to our workshops in January 2020 by a team from Létourneau, along with John Carmichael of Patrick J. Murphy & Associates. Once in our workshop, our pipe makers took a complete inventory of the Möller and Aeolian-Skinner pipework, making repairs as necessary. Fellow organbuilder Randall Dyer had also helpfully provided valuable scaling information and related documentation on Opus 11805 from his M. P. Möller archive.

Several stops were rescaled as part of the project, including the Great 8′ Harmonic Flute, the Great five-rank Cornet, the Swell 8′ Viole de gambe, and the Swell 8′ Voix Celeste to better obtain these stops’ characteristic colors. Other ranks were repurposed: a Möller 8′ Flûte céleste rank now serves as the Pedal 51⁄3′ Quint while the 13⁄5′ Tierce from the Möller Positif is now the Pedal 2′ Open Flute with the addition of new bass pipes. Of the new organ’s 83 ranks, some 21 ranks came from Aeolian-Skinner’s Boston workshops and another 46 ranks were made in Hagerstown, with the final 16 ranks having been built in St-Hyacinthe.

The Aeolian-Skinner and Möller electro-pneumatic windchests were restored to like-new condition in our workshops, with new unit chests built as needed. Designed by Claude Demers, the new organ case was built by our cabinetmakers from solid maple with walnut accents. The façade displays tin pipework from the Great 8′ Open Diapason, the Pedal 8′ Principal, and most prominently, the 8′ Trompette en chamade. The pipe shades were designed in a greatly simplified Gothic style and were machined on our CNC machine.

One of the project’s surprises occurred while examining the bass of the Pedal 16′ Contrabass in our woodshop. These twelve pipes were built in pine by Aeolian-Skinner to a lean scale and voiced with large beards. Without an organ built around them, their full length was revealed to show the pipe bodies were not quite true. The pipes had been deliberately built with “bellies,” meaning the middle of the pipe body is fractionally larger than the ends. Seen more frequently in metal string pipes, the theory is the bellied construction encourages prompt speech. This discovery presented an opportunity to document these pipes and how they were constructed.

The new organ—Létourneau’s Opus 136—made its way to Harrisburg in the spring of 2021, with the installation by our team continuing into the summer. The onsite flue voicing was fully underway by September, and the work was painstakingly executed by Samantha Koch and Christopher Bono, with help at various points from Megan Farrell (of Patrick J. Murphy & Associates) and John Johnson. The final phase of the voicing, Opus 136’s twelve ranks of reeds were voiced by Michel Godbout. The voicing process was assisted by a remote keyboard placed in the center of the sanctuary’s third pew. Connected wirelessly to the Solid State Organ Systems’ switching network, the keyboard allowed us to carefully evaluate sounds from another reference point beyond the console, usefully confirming or correcting voicing decisions made from the loft.

Though completed in late October 2021, Opus 136’s first solo concert took place on February 25, 2022, with virtuoso Ken Cowan at the console. In response to works by Widor, Litaize, and Bach—as well as transcriptions of works by Saint-Saëns and Wagner—the capacity crowd’s responses were nothing short of ecstatic. Mr. Cowan also brilliantly introduced a work commissioned for the evening, the Michelangelo Fantasy by Dr. Scott H. Eggert.

From the minister of music

Blessed by but not captive to a rich history, Market Square Presbyterian Church continues to serve its congregants and its community through worship and music. The major renovations of our pipe organ and sanctuary reaffirm our congregation’s commitment to the present and future of this church as a beacon of hope on the square.

When I interviewed for the post of minister of music, the Rev. Thomas Sweet told me of the church’s need to launch an organ project. After my arrival in July 2017, I soon found myself presenting to various committees the many failings of the church’s M. P. Möller organ. Co-chaired by Ellen Hunt (minister of music emerita) and me, our organ study committee interviewed several organbuilders, and we concluded that Létourneau was the best company for our project. After working with Létourneau to refine their proposal, the contract for the instrument was unanimously approved by the church’s board of trustees and session in January of 2018.

Létourneau Opus 136 reuses the best of the Aeolian-Skinner and Möller pipework to reorient the organ towards accompanying duties, leading hymn singing, and the performance of solo repertoire. Each stop was reworked and revoiced by Létourneau for remarkably cohesive choruses while assuring each stop’s musicality. On Létourneau’s recommendation, Market Square Church rebuilt the organ chambers with harder, denser surfaces to better reflect sound. Now, the full spectrum from the organ’s expressive divisions is projected into the sanctuary, especially in the bass and middle registers. With the old Positif cases removed from the loft rail, the rail itself was reconstructed to resemble the original from 1860, with minor differences to accommodate acoustical considerations and building codes.

The sanctuary renovation was occasioned by a desire to improve its acoustic for choral singing, hymnody, and the pipe organ while preserving the fine acoustic for the spoken word. This was achieved by installing a hardwood floor, with minimal carpeting in the aisles. The church took advantage of this opportunity to refresh the sanctuary with a new color scheme for the walls and ceiling, new pews with acoustically neutral cushions, and a new sound system.

Market Square Church has, from its earliest days, been located in the heart of Harrisburg, and it serves its members’ needs as well as those of the surrounding community. The church’s music ministry has been integral in this effort as a means of making God, beauty, and our shared humanity accessible to everyone, member or not. Generously underwritten by the Nedra J. Schilling Foundation, the organ project was conceived and approved under this principle as a gift to members and the community at large, now and for the future.

The members of Market Square Church as well as Harrisburg’s broader musical community have been delighted as we continue to explore the capabilities of our Létourneau pipe organ. I remain thankful to all who gave generously—especially during the pandemic—and I am grateful to the amazing team at Létourneau who delivered such an astonishing musical instrument!

Létourneau Pipe Organs, St-Hyacinthe, Québec, Canada; Gloria Dei Lutheran Church, St. Paul, Minnesota

Gloria Dei Lutheran Church is a large, welcoming ELCA congregation founded in 1908. Serving the Highland Park neighborhood of St. Paul, the church opened its present sanctuary in 1952 with subsequent additions to the church complex to accommodate the congregation’s growth and needs. An unusually active congregation, Gloria Dei undertakes its outreach and social justice ministries enthusiastically through various environmental, housing, hunger, and advocacy initiatives.

The pipe organ from Gloria Dei’s previous church building served the new sanctuary until it was replaced in 1962 by M. P. Möller’s Opus 9864. A three-manual instrument, the Möller employed significant unification throughout its modest specification, making the very most of its 36 ranks. The small and oddly shaped organ chamber dictated that the Möller had to be shoehorned in to a rarely seen degree. With chamber openings along one side of the chancel, most organ tone passed laterally across the chancel where it was then reflected off the opposite wall and dispersed out to the nave—but not before first passing through the deep chancel arch. As a result, the Möller was barely adequate for its many roles and was augmented in 1975 with the addition of an eight-rank Antiphonal division high on the back wall of the sanctuary, again by M. P. Möller.

After more than five decades of service, the Möller’s electro-pneumatic windchests were exhibiting typical signs of wear and leather failure, but the cramped organ chamber made chest repairs unreasonably difficult and costly. Cleverly, a unit chest was set up as an interim solution at the back of the Swell division to serve as a catchall for dead note actions as they came up. Pipes whose actions had failed were plucked from their original chests, reset on the unit chest at the back of the chamber, and the unit chest wired accordingly to the switching system.

The accelerating frequency of problems with the Möller was a serious issue, but the organ’s compromised location meant that a complete restoration—or even an all-new instrument in the same chamber—would not provide the improvement Gloria Dei was seeking. As part of their deliberations, the Gloria Dei organ committee looked carefully at all options as far as the organ’s placement and soon determined that the organ should go across the front wall of the chancel. Exceptionally, the organ committee’s discernment process blossomed into a larger sanctuary renewal campaign entitled “Rise, O Church.” In the words of Pastor Bradley Schmeling, “Rise, O Church is more than just buying a new organ or doing some remodeling. It’s about our dedication to be a growing, vibrant congregation ready to meet the needs of future generations and our neighboring community.”

In the meantime, Létourneau had been advertising a 1959 Casavant Frères pipe organ that the company had rescued from a closed church in Toronto, Ontario. The advertisement proposed completing the Casavant’s specification with several new stops, and this caught the attention of Gloria Dei’s organ consultant, Gregory Peterson, then of Luther College, and Tim Strand, Gloria Dei’s director of music.

The Casavant was an early instrument in Lawrence Phelps’s tenure as tonal director and displayed some of the first steps in the profound and rapid change of style Phelps oversaw in Casavant Frères organs. Vestiges from the era predating Phelps include the 16′ Flûte conique and the 8′ Aeoline stops in the Swell plus an augmented Pedal division. On the other hand, the Choir 4′ Koppelflöte, the organ’s narrow-scaled reed stops with parallel shallots, the generally thin-walled pipework, and the boldly scaled upperwork were examples of Phelps’s emerging aesthetic. As the Casavant featured no casework or façade pipes, our advertisement also offered new casework with façade pipes for the expanded instrument.

With the Casavant’s 34-rank specification as a starting point, we expanded the instrument with eighteen additional ranks to complete each of the instrument’s four divisions. To the Great division, we added a 16′ Contra Geigen stop and a soaring 8′ Flûte harmonique, as well as trumpet stops at 8′ and 4′ pitches. The Swell division was already largely complete; the only changes were the replacement of the 8′ Aeoline with a proper 4′ Principal stop and the addition of a new 16′ Bombarde stop with full-length resonators scaled to match the 8′ Trompette and 4′ Clairon.

Devised in an era when Positiv divisions were coming into fashion, the original Choir division was judged to be short on 8′ foundation tone. The addition of new 8′ Geigen Principal and 4′ Geigen Octave stops addressed this point, as well as the new undulating rank to go with the 8′ Spitzflöte. A new three-rank Sharp mixture completes the Choir’s principal chorus, offering more brilliance than its counterparts in the Swell. To augment the existing Swell 8′ Oboe and Choir 8′ Clarinet stops, we added a delicate 8′ Cor anglais as a third solo reed option.

The Pedal division was built on a rich-toned 16′ Contrabass stop in zinc, though it was originally extended to play at 8′ and 4′ pitches. The original 8′ extension of the 16′ Subbass rank was maintained, but new 8′ Principal and 4′ Choral Bass ranks plus a three-rank mixture were added to provide a true pedal chorus. Bold reed stops at 16′ and 8′ were also added to give the Pedal the necessary grandeur and color.

The Casavant electro-pneumatic windchests in solid mahogany were restored in our workshops, with new electro-pneumatic chests provided as needed. The original chests’ 68-note compass was retained and carried over into the new windchests as well. The organ’s painted casework was designed by Claude Demers and was constructed from maple; it features polished pipework in 70% tin from the Great 16′ Contra Geigen, the Great 8′ Principal, and the Pedal 8′ Principal ranks.

The eight-rank Antiphonal division and its 8′ Trompette en chamade with polished brass resonators were retained as part of the project for added support from the rear of the nave. The Möller electro-pneumatic windchests were restored, while the Antiphonal’s wind system was rebuilt to incorporate a new blower.

The instrument is played from a new three-manual console with the shell made from rift sawn red oak and the interior panels in walnut. Built to be as compact as possible for good sightlines, the console offers organists 999 levels of memory, twelve General pistons with sequencer, a sostenuto effect for each manual, a Great-Choir Manual Transfer feature, and a Pedal Divide coupler. Numeric displays showing the positions of the Swell and Choir’s expression shades are included, as is Solid State Organ System’s Organist Palette. An iPad-controlled suite of features, the palette includes a wireless record-playback interface, visual management of the General piston sequencer, a transposer, and control of the various sostenutos and the Pedal Divide coupler.

The organ was delivered to the church in late October of 2022 and was installed in collaboration with the Organ Clearing House. The voicing of the instrument commenced after Thanksgiving with the welcome participation of Jonathan Ortloff for several weeks, and the project was wrapped up in the New Year.

Létourneau’s Opus 137 was played by Tim Strand in its first solo concert on April 23, 2023. Seminal works by Cook, Bach, Duruflé, and Vierne were heard by a large and especially enthusiastic crowd, as were the world premieres of two new pieces. The first, Partita on “Rise O Church, like Christ Arisen” by David Cherwien, is based on the hymn of the same name, tune Surge Ecclesia (written by Mr. Strand), and featuring words written by Dr. Chewien’s late wife Susan. The second work was a rich new setting of the Swedish tune “The Earth Adorned in Verdant Robe” for saxophone and organ by Robert Buckley Farlee, with Kurt Claussen playing the soprano saxophone.

Many people played important roles—some visible, some less so—in helping us and Gloria Dei Lutheran Church realize this organ project. We would like to thank Tim Strand, Gregory Peterson, Pastor Bradley Schmeling, Mike Kruger (chair of Gloria Dei’s Sanctuary Renewal Task Force), Teresa Sterns (project manager for Gloria Dei), Todd Kraft and Sara Du of HGA Architects, the team at Langer Construction, the Organ Clearing House, and the Ortloff Organ Company.

Orgues Létourneau, St-Hyacinthe, Québec, Canada; First United Methodist Church, Lubbock, Texas

Even when measured by expansive Texan standards, First United Methodist Church in Lubbock is extraordinary in scale. The church’s Gothic bell tower is visible from just about anywhere in downtown Lubbock. The church campus sprawls over two city blocks and includes spacious wings for music, Christian education, youth, and even physical fitness. Completed in 1955, the sanctuary seats over 1,800 people, and its spectacular rose window is reportedly among the eight largest in the world. Confronted with such a voluminous space, organ enthusiasts and builders alike would be forgiven if their thoughts gravitated towards grand schemes. Nonetheless, First Methodist’s sanctuary opened its doors in March of 1955 with M. P. Möller’s Opus 8530, a positively ascetic instrument of 38 ranks spread over seven divisions and located in all four corners of the sanctuary. The organ was played by a three-manual console. Having studied the original pipework and seen the original wind pressure markings as part of this project, the Forrest Memorial Organ was surely understated in its effect.

Möller added a new Great division to the instrument in 1980, introducing visible pipework set on cantilevered chests bracketing the rose window. The original Great was repurposed as a Positiv division, and the other divisions were revised in the fashion of the day, largely replacing foundation tone with new mixtures, cornets, and mutations. Towards the end of the same decade, Möller replaced the 1954 console with a new four-manual console, which allowed the addition of several digital voices by Walker Technical Company.

Möller’s Opus 8530 arrived at its final form a few years later when two new stops built by A. R. Schopp’s & Sons were added to the Swell division, a 4′ Blockflöte and an 8′ Tuba. Now at 54 ranks and supplemented by nearly a dozen digital voices, the instrument could fill the church with sound. The Möller pipework was nonetheless uniformly under-scaled for the space and sounded forced as it was inevitably “pushed” for maximum output. For such a large room, the Pedal division was also curiously limited to two dedicated ranks, a skinny wooden Contrabass and a generous Bourdon.

By the mid 2010s, parts of the instrument were failing. Some of the organ’s larger reed pipes were collapsing, wind reservoirs were audibly leaking, expression mechanisms were unreliable, and the instrument’s electro-pneumatic windchests were ciphering with regularity. The church’s organ committee, ably led by Mr. Danny Johnston, explored options to replace the obsolete Möller mechanisms while retaining as much of the pipework as was practical. The committee travelled to listen to various instruments in Texas, and four companies were invited to submit proposals. Two instruments convinced the committee that Létourneau was the right choice: our Opus 88 at Saint Andrew United Methodist Church in Plano (four manuals, 77 ranks) and our Opus 127 at Saint Mark’s School of Texas in Dallas (three manuals, 61 ranks).

After listening to the church’s aspirations for the project, studying the situation carefully, and surveying the Möller organ’s pipework, we developed a proposal for First United Methodist in several phases that retained nearly thirty ranks from the previous instrument. The project kicked off in the spring of 2019 with the replacement of the Antiphonal Great and Antiphonal Swell organs on either side of the gallery with new Antiphonal and Echo divisions totalling eleven ranks; the voicing was completed later that summer. Independently expressive, these two divisions served as a small but capable instrument for over a year, proving their ability to accompany the church’s adult choir of over seventy voices. With the completion of the chancel organ, these divisions draw sound from the chancel through the long nave, surrounding the congregation with sound without drawing attention to themselves.

As soon as the gallery organ and its two-manual console were ready for service, the dismantling of the chancel organ began. In all parts of the organ, pipes slated for reuse were repaired, cleaned, and in the case of the Möller pipework, liberally rescaled for the new instrument. For example, the scales of the Swell and Antiphonal 8′ Open Diapason stops were enlarged by three and four pipes, respectively. Two of the Möller’s narrow stopped basses were replaced with new wooden pipes for a fuller sound in the 8′ octave. After the addition of seven new pipes at various points in the tenor through soprano octaves, the Möller 8′ Harmonic Flute was completely transformed into the present Antiphonal 4′ Traverse Flute.

The first portion of the chancel organ arrived in Lubbock towards the end of 2019, and a second shipment arrived in early 2020. As the full extent of Covid-19 made itself known, how to continue the organ’s installation became a preoccupation as lockdowns and international travel restrictions sidelined our company’s Québec-based organ builders. After some logistical reshuffling, we engaged a crack team led by Samantha Koch and Daniel Hancock to continue the installation in Lubbock that included the talents of Ryan Boyle, Brian Seever, and Jon Lester. (Daniel and Samantha subsequently joined our team in Québec at the end of 2020.) This last phase of the installation included the Great division and the four 16′ tin façades with their oak casework around the church’s chancel area.

Our Opus 135 is playable from two new consoles. There is a large and traditional four-manual stopknob console in the chancel, and a two-manual console in the gallery with touchscreen controls. The gallery console offers the same stop controls as its larger brother at the other end of the sanctuary, giving organists complete control of the instrument in real time. Both consoles also share the same capture system, allowing the organist to move from one end of the building to the other without concern for registrations. The system boasts 999 levels of memory, as well as an independent sixteen levels of memory for the divisional pistons. Using Solid State Organ System’s powerful MultiSystem II platform, the switching system in all four organ chambers is linked by fiber optic cable for effortlessly rapid communication. Further, the organ has SSOS’s Organist Palette, an iPad interface allowing wireless record-playback throughout the sanctuary, a transposer, and a clock with stopwatch. The Organist Palette offers controls to adjust the General piston sequencer, the various Sostenuto functions, and the point of division for the Pedal Divide feature. Both consoles also use a programmable expression matrix, a concept we borrowed from Richard Houghten, which allows all five of the organ’s expressive divisions to be interchanged between any of the consoles’ three expression pedals.

The new organ’s tonal design took shape in a comfortably English mold, based on a large and noble Great division. Split between the two chancel façades, the Great offers colorful foundation stops, an elegant 16′ principal chorus topped with a six-rank mixture, and large-scale trumpets at 8′ and 4′ pitches. The 16′ Double Diapason is extended to play as the 8′ Open Diapason No. 2; the rank’s slotted pipes are voiced for a harmonically richer timbre to contrast with the larger, more foundational Open Diapason No. 1.

The Swell offers all the dynamic and tonal range one would expect for choral works or organ repertoire. Its specification is disciplined, containing the organ’s secondary principal chorus, a richly colored string and celeste, and a lighthearted chorus of flutes. The Swell foundations smooth the buildup between the Choir and Great divisions but equally reinforce the Great in orchestrally minded registrations. The Swell’s battery of trumpets with English shallots dominates the division without stretching above their station; they enrich the Great ensemble with nuance and color.

The Choir is the tertiary division, with a range of mezzo foundations, from its slotted principals to the open Concert Flute to the delicate Lieblich Gedackt rank. The organ’s softest stops, the Erzähler and Erzähler Celeste, possess more character than a typical Flute Celeste. When used in tandem with the Echo division, the effect is an ethereal shroud over the sanctuary, ideally proportioned to introduce solo colors from the Great, Swell, or Solo. With all the harmonic vibrancy and carrying power of a solo stop, the Choir’s cornet décomposé is still controlled in power such that its mutations can reinforce the principals for smaller contrapuntal works or in alternatim passages with other divisions. Möller’s 8′ English Horn from 1954 was thoroughly revoiced, and its hollow, peaky timbre contrasts beautifully with the Swell’s warm 8′ Oboe. The new Clarinet was fitted with teardrop shallots for a slightly bolder timbre than a prototypical English example without limiting its utility. Both reeds are balanced for use in dialogue with each other against the Swell, but they too can also be strengthened with elements from the cornet.

The Solo division stands out with a strong Doppelflöte and a pair of warm reverse-tapered gambas. The 8′ Tuba pipes by A. R. Schopp’s & Sons merit special mention for their resonators’ enormous scale, as well as their early jump to harmonic length at 4′ C. The Tuba rank was revoiced on nearly seventeen inches pressure with a round, fundamental tone that works beautifully as a solo voice—especially when employed in octaves—but can also buttress the whole ensemble. It will contrast magnificently as the darker foil to the future Trompette en chamade to be installed above the rear gallery. We also added a new 16′ octave to the Tuba using shallots and heavy zinc sheets supplied by Schopp’s for seamless cohesion. Intended to give the pedals the last word in extraordinary circumstances, the 16′ Ophicleide’s effect is especially astonishing from the chancel console!

The organ’s twelve-rank Pedal division features independent metal principals at 16′, 8′, and 4′. A five-rank mixture completes the Pedal chorus, with the mixture incorporating a soft tierce rank for a subtly distinctive timbre. The pedals are reinforced by a large 16′–8′ Open Wood rank and the restored Möller 16′–8′ Subbass, as well as a 16′ Trombone and 8′ Trumpet on nearly six inches pressure. The Pedal is also augmented by four digital 32′ stops provided by Walker, including a penetrating Contra Bass, a subtle Bourdon, a vibrant Contra Trombone, and a milder Contra Fagotto, with this last voice usefully enclosed within the Swell division.

As with any Létourneau instrument, a great deal of reflection went into how Opus 135 could best serve a host of musical needs, whether it is supporting a modern worship service, accompanying a grand choral anthem, or serving as the vehicle to present the organ’s repertoire. We believe the specification bears this out. With 75 ranks and five expressive divisions, there are endless possibilities for creative registration without having to turn the instrument on its head.  Each of the main divisions is based on foundations appropriate to the space, with incisive 16′ ranks that enhance their respective choruses without opacity. At the other end of the spectrum, great attention was paid to the role of upperwork with the happy result that the mixtures and higher pitches add presence and texture without overwhelming the balance of the chorus. The overall effect is one of grandeur, cohesion, and warmth.

We have thoroughly enjoyed working with so many fine people at First United Methodist Church during the course of this thrilling project, despite some unexpected twists and turns. Our work has been greatly helped at various points along the way by Danny Johnston, Dr. Seung-Won Cho, David Warren, Keith Bell, and the Reverend Todd Salzwedel. We are also grateful to Mrs. Mary Frances Baucum and the church’s Board of Trustees who were so supportive of the organ committee’s work and recommendations.

In the broader context of the Létourneau company, our Opus 135 for First United Methodist Church is the first instrument completed under the proprietorship of Dudley Oakes (Read about this here). This pipe organ is simultaneously the logical continuation of the artistic evolution that the company was already on and a first expression of our renewed pursuit of tonal excellence. Within the company, there is a growing sense of being in a strong position. The second generation of leadership has many lessons from the past to guide us into the future while still having the freedom to advance in new and exciting directions. With several exciting projects in the years ahead, we invite you to watch this space!
