In the Wind: recording stoplists and registering sounds

John Bishop

Ringing through the night

Wendy and I left our apartment in Greenwich Village in March of 2020, fleeing from the burgeoning epidemic to the relative safety of our home in Maine. Although the current second wave with choices of variants is ravaging the unvaccinated population there now, through the summer of 2020 Maine was one of the least affected states in the early stages of the epidemic with cases counted on your fingers compared to the tens of thousands each day in New York City. We ventured back into New York after sixteen months, gingerly returning to the life we have loved there. Finding our neighborhood transformed with outdoor dining consuming parking spaces and congesting sidewalks, we decided to leave the city. We had a ten-year run there, and we are the richer for it.

With our place in Maine as a comforting constant, we have moved to Stockbridge, Massachusetts, in the Berkshire Mountains, barely five miles from Tanglewood, the summer home of the Boston Symphony Orchestra. We are living four tenths of a mile from Saint Paul’s Episcopal Church (across from the Red Lion Inn), where my grandfather was rector during my pre-teen and teenage years and where I practiced endlessly on the Roosevelt organ, sadly “baroque-ified” so that much of the original grandeur is gone—but as a thirteen-year-old, I thought it was wonderful.

Our house is about 600 feet from the Children’s Chime Tower, a lovely structure on a picturesque village common, with eleven bells, the largest of which tolls every hour. We can hear it from our bedroom, so we give each other morning reports of which hours we heard. My tuner’s ear gets mired in identifying the overtones, an arcane version of counting sheep, and I have found myself thinking anew about the role of overtones in tonal music and the development of the pipe organ.

How do you make an organ stop?

In February 2017, I gave a lecture titled “Pythagoras, broccoli, and the development of pipe organ stop action” for the Presidents’ Day Conference of the New York City Chapter of the American Guild of Organists. I was inspired to lecture on this when a family member casually asked why the voices of the organ are called stops? Wouldn’t it make sense to call them “go’s?” After all, we pull out stops to make an organ go.

Pythagoras lived on the Greek island of Samos in the eastern Aegean Sea, barely a mile from Turkey. It is near the popular resort islands of Naxos and Mykonos and about 170 miles south of Lesbos, also close to the Turkish coast, which has been central to the continuing refugee crisis in the region. Pythagoras (c. 570–495 BC) was a mathematician who famously gave us the eponymous theory defining the length of the hypotenuse of a right triangle (A² + B² = C²) and who discovered the series of overtones present in any musical note. Walking past a blacksmith shop, Pythagoras noticed that the workers produced different pitches as they hammered on their anvils and thought at first that it was the size of the hammer that affected the pitch. It did not take much experimentation to determine that it was the size of the anvil. Our tower bell is a good example. You get the same pitch if you hit the bell with a pencil or a hammer.

Organists know the overtone series by the pitches of our stops. Unison pitch is 8′. The first overtone is an octave higher (4′), the second is an octave and a fifth (2-2⁄3′), the third is two octaves higher (2′), the fourth is two octaves and a third (1-3⁄5′), the fifth is two octaves and a fifth (1-1⁄3′), then 1-1⁄7′, 1′, etc., ad infinitum. Organ stops rarely go higher than 1′, although we often find pitches like 1⁄2′, 1⁄3′, 1⁄4′ in the lower octaves of high-pitched compound stops like Cymbals and Scharffs.

We start with the earliest forms of pipe organs such as the hydraulis, created by Ctesibius of Alexandria in the third century BC, which had a pressurized wind supply regulated by the weight of water, a row of primitive organ pipes, and a keyboard-like mechanism for the choosing of notes. That instrument and many of the following stages of evolution had a single set of unison pipes. As those organ builders began to understand their sophisticated musical tones and became aware of the overtones, it was natural to add a set of pipes that spoke at the first overtone, an octave higher, to brighten the tone. Then, perhaps, a second rank of unison pipes was added to beef things up, then another four-footer. Imagine the light bulb over the guy’s head when he thought of adding a rank at the second overtone, the world’s first Nazard.

This primitive organ came to include a dozen or more ranks and was known as a “Blockwerk.” There was no stop action, just a big powerful chorus of voices bellowing simultaneously, so the next innovation was to separate the windchest into two parts, with the original unison rank on one wind supply, and the rest of the multitude on the other whose wind could be shut off by a separate control. When I was writing my lecture, I conferred with several colleagues well versed in organs of the fourteenth and fifteenth centuries and learned that the original name for that control was “doof,” an old Dutch word that meant either “dumb” (as in deaf and dumb) or stupid. One Dutch colleague told me that “doof” was the nickname her grandmother had for her grandfather, and her family assumed that she was intending both definitions. In modern English, the first pipe organ stop action was intended to turn things off. Stop.

That led to family discussions on the original question. We “pull out all the stops” to make a loud noise on an organ or to give a situation or task our best shot. “This year when spring cleaning we’re going to pull out all the stops.” We pull out a stopper to make liquid flow, like wine from a bottle, and conversely, we use a doorstop to keep a door open.

Use your ears.

The common registrations for French Classic organ music give us some of the clearest examples of exploiting the overtones of each stop. Think of the Cornet decomposé, literally a dismantled five-rank Cornet with flutes at 8′, 4′, 2-2⁄3′, 2′, and 1-3⁄5′. Each has its own rich overtone structure, but collectively, they mimic the harmonic structure of the reeds like Trompette or Cromorne. The Trompette ranks in French Classic organs had broad scales and powerful tones from the bass, through the tenor, and into the middle octave of the keyboard before they started to peter out toward the treble. The five-rank Cornet starts at middle C and is intended to beef up the treble of the reeds, and you can imagine where Clérambault got the “Basse et Dessus de Trompette” and Balbastre and d’Aquin the rollicking pairings of Cromornes and Cornets in their noël variations.

The Cornet decomposé allows the fascinating variety of combining two, three, or four of those pitches to achieve different sonorities, and those ranks can be added individually or in combinations to the Cromorne, Hautbois, or Trompette to spice things up, like adding a dash of cayenne to an otherwise stolid dish.

When I was an apprentice in Ohio in the mid 1970s, my mentor John Leek and I went to tune a large M. P. Möller organ for the first time. It was a neo-Baroque rebuild of an earlier Möller that had an impossible Positiv division with a chiffy Gedackt, a smarmy 4′ flute, and a terribly high-pitched Cymbal, the kind that at first glance looks like there are only six different sized pipes making up the sixty-one notes of three ranks. What do you use to tune that squealing thing? There was a yellowed index card lying on the tuning perch with a neat suggestion: tune the Krummhorn to the Great 4′ Octave, far away but still easy to hear, and tune the Cymbal to the Krummhorn, being sure that each note of the Krummhorn is still in tune. The infinitely high overtones of the Krummhorn pipes clearly matched the stratospheric pitches of the pencil-sized pipes.

I use that technique to this day when tuning higher-pitched mutations. The top octaves of the Tierce ring out clear as a bell against an Oboe or Trumpet because those partials are so strong in the reed pipes. Any tuner’s ears are trained to hear those overtones in single pipes. You can learn this by playing a note in an Oboe (the tenor octave is usually the clearest) and turning a 2-2⁄3′ stop on and off, or by playing a fifth above in a different stop. Reinforcing the second partial that way helps your ear pick up the partial in the reed pipe alone. I love that demonstration as an important lesson about how musical tones work.

Thicken the batter

When you combine stops that speak in intervals with one another, you build a sassy pile of dissonance. Imagine playing C with an 8′ stop whose second partial (overtone) is G, an octave and a half above. Add the 2-2⁄3′, which speaks a G, with a second partial of D. Add the 1-3⁄5′, whose second partial is B. With those three pitches playing, you are hearing a cluster of several C’s, G’s, D’s, E’s, and B’s all at once. When you add another layer of partials it becomes a twelve-tone cluster. This conglomeration helps explain why mutations can be so difficult to tune. Consider a mixture tuned in equal temperament and play C. The ranks of a usual mixture are speaking octaves and quints (C’s and G’s). The ranks of the mixture are tuned pure to each other, but the intervals on the keyboard are tempered so you are hearing both tempered and pure fifths when you play chords. This is true to some degree in any unequal temperament because it is impossible to temper every interval pure. It may seem as though I am describing unbearable dissonance, but in fact, it is a richness comparable to twenty violins playing in unison in a great orchestra. It is impossible for them all to play identical pitches, but they are close enough to each other that we hear it as three-dimensional richness.

A palette of color

Looking at the rows of pipes inside an organ, you can see a variety of shapes and sizes and a variety of materials used to make them. We refer to the differing diameters of pipes of the same length as “scaling.” An 8′ pipe with a large diameter (diapason) produces a broad tone, while one of narrow scale (string) produces a keen tone. Broad scales and softer material like wood or metal with higher lead content emphasize the fundamental pitch. Harder metal (high tin content) emphasizes the development of higher partials and produces brighter tone. That is a simple description of the rich, earthy tone of a Skinner diapason as compared with the brightness of principal pipes in an organ by Rieger or Beckerath.

Various shapes of resonators like the “choo-choo-train” tops of English Horn pipes or the narrow brass tubes leading to cylindrical resonators of a Schalmei affect the harmonic development of tone and create different timbers. A Clarinet has a cylindrical resonator like a Cromorne. Adding a bell at the top of a Clarinet pipe enforces the fundamental, adding the richness to create a Corno di Bassetto. A “usual” Oboe has a double taper, a long, narrow taper that opens to more of a flare at the top. An Orchestral Oboe has a very thin scale and a gradual taper. A Tuba and a Trumpet are more or less the same in production of tone, but the Tuba has a larger scale and usually higher wind pressure. The placement of scrolls for tuning and regulating also affects the timbre of a pipe.

Similarly, some flue pipes have particular shapes that define the tone. A Rohrflöte is usually a capped metal pipe with a chimney soldered to a hole in the cap. I imagine that the hole in the cap frees the quint, as the presence of a stronger second partial creates the signature brightness of that flute. Ernest M. Skinner and others often made Rohrflötes (also called Chimney Flutes) of wood, drilling through the handle of the stopper to create the chimney. The tapered cap with a small opening at the top of a Koppelflöte pipe has a similar effect.

A tapered flue pipe like a Spitz Flute or Gemshorn, wide scale at the mouth and narrow scale at the top, is a hybrid. The wide scale allows a wide mouth that creates greater tone, but the narrow scale at the top points it toward a string. Many mid-century Aeolian-Skinner organs, especially in the Joseph Whiteford years, have gently tapered principal pipes. A colleague once joked while pointing out Whiteford’s house near the Charles River in Boston, “It’s the one with the tapered doorway.”

All these variations give us the rich palette of tone colors in our pipe organs, and it all relates to the manipulation of the overtone series. Pythagoras may not have foreseen the comparison of a Gedackt and a Chimney Flute, but he discovered and described the math that makes it possible.

So why the broccoli?

The title of my lecture was “Pythagoras, broccoli, and the development of pipe organ stop action.” A thirteenth-century Italian mathematician named Fibonacci discovered a series of numbers that is found throughout nature. The infinite Fibonacci series starts 1 + 1 = 2, 1 + 2 = 3, 2 + 3 = 5, 3 + 5 = 8, etc. Each successive number is the sum of the preceding two. This series defines the spiral of a nautilus shell, the diminishing tiles of a pineapple or pinecone, and yes, the diminishing spirals of Romanesco broccoli. It also defines the diminishing intervals between musical overtones. Pythagoras had the numbers right 1,800 years before the Fibonacci series was identified.

Nunc dimittis

Friend and colleague Richard Houghten of Ann Arbor, Michigan, passed away on December 29, 2021. Dick was the American presence of Solid State Organ Systems (SSOS, formerly SSL), which has been producing excellent control systems for pipe organs for more than a generation. He had also served as the American representative for Laukhuff, helping dozens of us choose what products we needed and helping us with the complications of ordering products internationally.

He installed SSOS systems in dozens of America’s greatest organs and was available as mentor and guide, helping many of us find our way out of technical problems. I spoke with him, asking for advice about a complicated organ while he was recuperating from surgery coupled with complications, and though he was confined and suffering, he was eager to help, answering my questions and providing follow-up information.

His skills, wisdom, and thoughtful presence added much to the world of organ builders, and I am grateful to have known him as a colleague and a friend. He cared deeply about the organ classes at the neighboring University of Michigan, inviting them to his home and workshop and sharing his experiences with them. Above everything, Dick was a gentleman in every sense of the word. I miss him, and I will remember him always.

Designed for the space

When an organ builder accepts the challenge of creating a new instrument for a particular space, they incorporate all the features of the room: architecture, acoustics, ambient climate, and building surfaces like floors, walls, and ceilings. All are factors that influence the design of the organ. Many builders have a portable windchest equipped with blower, regulator, and sample pipes that they ship to the church, allowing them to hear and compare pipes of different scales at different wind pressures in the room where the organ will go. If the walls, ceilings, and floors are made of materials that absorb sound, the builder recommends changing them by replacing carpet with stone tiles, sealing soft ceilings with material that reflects sound, and doubling or tripling the thickness of sheetrock walls.

A formula is developed that includes the scope and content of the organ, the scales of various ranks of pipes at certain wind pressures, and the adaptation of the room that encloses it. It is both a scientific equation and an artistic composition. It is purposeful and intentional; there is no sense of “hit or miss.” Building a pipe organ is an expensive adventure, and it is important to get it right.

Perhaps I am describing an ideal. Often there are compromises because of budget limitations or conflicts with other groups within a parish about changing the look and feel of a sanctuary—a congregation that is accustomed to carpets and pew cushions may not part with them easily. In any case, it is customary for an organbuilder to spend a lot of time and effort creating the most effective equation considering the limitations.

If each instrument is carefully planned for a specific room, how can it be that we routinely relocate organs from one place to another? That has been central to my work as director of the Organ Clearing House for nearly twenty-five years. We accept as new listings those organs we judge to be good candidates for relocation, and we help guide the placement of an organ based on our sense of the same design equation used to plan a new instrument. Sometimes it is necessary to design and build a new case to get the architecture right. In other cases it helps to rescale some of the stops to increase the depth of the sound of the organ. Increasing the scale involves making the pipes larger in diameter relative to their length by adding new pipes for the lowest few notes, moving the pipes up the correct number of holes and cutting them shorter to make the correct pitch. Increasing scale along with raising wind pressure will make an organ more bold and powerful, ready to fill a larger space with sound.

A couple years ago the Organ Clearing House organized the relocation of Gabriel Kney’s Opus 93 (two manuals, forty ranks), built in 1980 for First Community Church of Dallas, Texas. The organ was offered for sale because that church decided to divest itself of real estate to create an endowment it could administer to meet specific needs of the community, confining the organized worship to more simple surroundings. The organ’s original home was a contemporary room with a sharp-pitched roofline, something like an A-frame. It was moved to a richly decorated chapel at Saint Meinrad Seminary and School of Theology in Saint Meinrad, Indiana.

The organ has classic lines and proportions. It is housed in a free-standing “honey” oak case with a narrow lower section that spreads wider midway up to accommodate a common three-tower design. The towers have flat roofs that neatly parallel the flat but coffered ceiling of the chapel. The honey color of the case complements that of the wooden chairs, while walls and ceiling are a similar but darker hue. Someone seeing the organ for the first time in the chapel at Saint Meinrad might think it was originally designed for that room.

The bright and powerful classic tones of the organ carry effectively through the large space, which with its contoured ceiling provides a rich acoustical surrounding. Mr. Kney’s equation for the creation of an instrument for the church in Dallas transposed easily to the different surroundings.

About twelve years ago, we relocated a 1916 Casavant organ, Opus 665, from the “downstairs church” at the Basilica of Saints Peter and Paul in Lewiston, Maine, to the nave of Church of the Resurrection on East Seventy-Fourth Street at Park Avenue in the Upper East Side of Manhattan. Four 16′ stops from previous organs in the church were incorporated and added to the specification. The Pedal Principal 16′ became the Great 16′ Violone; the Gemshorn 16′ extended the Postif Dulciane 8′ to play at 16′ on both manual and pedal; the Pedal Bourdon 16′ serves as an independent pedal stop with the remote Positif; and the Pedal 16′ Quintadena was cut shorter to create a 10-2⁄3′ Quinte, which effectively increased the scale of the stop by five notes. A fourth “new” 16′ stop was created with the extension of the Récit 8′ Hautbois with a new bass octave so the rank could speak at 16′ pitch on manual and pedal, making a total of four sixteens and a ten-and-two-thirds added to the already sonorous Double Open Wood, Subbass, and Trombone. Pretty good foundation for a forty-rank organ.

Originally, there were two Open Diapasons on the Grand Orgue. We left one in that division as the usual foundation of the main principal chorus, and the other, larger diapason became the base of a new Solo division, which includes a restored Skinner French Horn and new replicas of a Skinner Harmonic Flute and high-pressure Tuba.

These and other modifications transformed the organ from a downstairs small-town organ to an upstairs big-city organ. You can read about this instrument and follow links to see full specifications at resurrectionnyc.org/organ.html.

Monumental art

I am thinking about moving large objects that were made for specific places after reading an article by Hilarie M. Sheets published in The New York Times on October 13, 2023, “Moving a Masterpiece to LaGuardia is a High Wire Act.” Orpheus and Apollo is a metal sculpture 190-feet wide and forty-feet deep comprising 188 Muntz metal bars¹ suspended in a system of complex angles from 444 woven stainless-steel wires. The wires were fastened to eye bolts in the ceiling personally by the sculptor Richard Lippold (1915–2002) in the grand lobby of Philharmonic Hall in New York City’s Lincoln Center. The work was in place for the opening of the hall in 1962 (E. Power Biggs, Catharine Crozier, and Virgil Fox shared the dedication recital of the Aeolian-Skinner organ there that year), but fifty years later conservators grew concerned about the stability and safety of the massive complex work. The wires that suspended the heavy metal bars were fraying, and as a second reconstruction and renaming of the hall was being planned, Orpheus and Apollo was documented, dismantled, and placed in a storage facility in New Jersey. Just like seemingly countless pipe organs I have seen go into storage, there was little hope that the grand piece of art would ever see the light of day.

Architecture critic Paul Goldberger, lecturer at the Parsons School of Design and Pulitzer Prize winning author of the column “Skyline” in The New Yorker magazine, was serving as consultant to Lincoln Center for the selection of the architect of the transformation of Philharmonic Hall, then Avery Fisher Hall, into Geffen Hall, and the Port Authority of New York and New Jersey for the reconstruction of LaGuardia Airport. As he followed the planning of those two major projects, he noticed similarities in the two monumental spaces and conceived the idea that Orpheus and Apollo might be installed at LaGuardia. “Lincoln Center had a sculpture in search of a space, and the airport had a space in search of a purpose,” Goldberger said of the atrium at LaGuardia. The article continues, “With the sculpture as the centerpiece of this new gathering spot with a mezzanine lounge, Goldberger feels it is ‘entirely consistent with what Lippold intended, which was to enliven an architectural space, to have people moving around it.’”

Peter Flamm, executive director of the Lincoln Center Development Project, said, “We believed LaGuardia to be the best solution that provided a manner to appropriately appreciate the piece.” Lincoln Center not only gave Orpheus and Apollo to the Port Authority but also funded the restoration and re-lacquering of the 188 metal bars. When conservator Marc Roussel dismantled the sculpture, a precise 3-D scan of the original installation was created—that was included in the gift to the Port Authority.

Frank Rapaccioli of the fine-arts mover Dun-Right Carriers was responsible for the installation at LaGuardia, converting the model into a format that mapped out the placement of the screw-eyes and the lengths of the new steel wires that determined the height of each end of the sculpture. The original layout had to be changed to accommodate the lower ceiling in the LaGuardia atrium, and conservator Roussel was charged by the Lippold Foundation to observe and approve those changes in the interest of preserving as much of the integrity of the original installation as possible.

The installation took thirty days. At the outset, there was a lot of trial and error as the installers and curators realized how easy it was to leave wires rubbing against others, and many pieces had to be cut down and moved even a few inches for clearance. As the work progressed they got the hang of it, and there were far fewer “back steps” in the second half of the project.

The article concludes, “While profoundly disappointed about the sculpture’s displacement, Anthony C. Wood, executive director of the Ittleson Foundation, which originally funded Orpheus and Apollo at Lincoln Center, is relieved that it was so well documented and hasn’t been consigned to storage, in pieces, for eternity. Putting it in a new and exciting home, where it will be seen by more people, is the silver lining,” Wood said. “But you don’t have to be an art expert to know that it’s going to be different. How could it not?”²

This story speaks of inspiration, cooperation, and flexibility. Paul Goldberger had the great idea, and officials and conservators at Lincoln Center and the Port Authority cooperated to make it happen. The fact that the iconic sculpture would not fit in the new space in its original form did not stop them. They reconfigured it to fit, retaining as much of the work’s integrity as possible. The overriding sentiment was that it is better to have the work renovated and installed in a busy public place than to have it languish in storage, never to be seen again.

§

We at the Organ Clearing House have faced just this question with numerous pipe organs. Imagine a large three-manual, nineteenth-century organ built by E. & G. G. Hook or Henry Erben. It is installed in an immense balcony, stands thirty or forty feet tall, and has a footprint thirty feet wide by twelve feet deep. (I am thinking of a particular organ I visited last week.) What newer church can accommodate an instrument of that size? But when a potential purchaser who loves the sounds of organs from that era arrives representing a church that has adequate space for this organ but would wish to equip it with electric stop action and a solid-state combination action, I would be tempted to refuse on the grounds that the historic monument should be preserved without alteration. What do I achieve? Nothing. The interested party moves on, and the organ remains dormant.

Why not consider adapting that grand organ to suit the needs of a modern congregation? After all, there would be only a few churches that could house such a massive organ. A careful restoration of the windchests, reservoirs, keyboard and stop action, and pipes could be enhanced by adding electric solenoid stop action motors to the existing mechanical stop action. The only actual violation of the original organ would be drilling piston buttons into the keyslips between the keyboards, and the original keyslips could be retained in case someone later chose to reverse the project and remove the electric action.

The organ would be used and admired, and it would sound just as it did when it was new. It would leave the vast assortment of historic organs languishing in storage or in abandoned buildings.

When conservators restore a piece of furniture owned by Marie Antoinette, they place it behind velvet ropes, keeping visitors from touching it. When we restore or renovate a pipe organ, we intend it to be used. The purpose of preserving an organ is so people can hear the timeless sounds.

There is a grand relief-plaster sculpture thirty feet wide called The Spirit of Transportation in a secondary waiting room in the Thirtieth Street Station in Philadelphia. One passes it on leaving the main concourse and heading for the public restrooms or the Amtrak first class lounge. It was created by the Austrian sculptor Karl Bitter (1867–1915) who emigrated to the United States in 1889. The Spirit of Transportation was created for the opening of Philadelphia’s Broad Street Station and depicts the history of transportation from ox carts to fanciful imaginations of air and space craft. When the Thirtieth Street Station was built, its predecessor the Broad Street Station was demolished, but curators and designers had the foresight to preserve this and several other important sculptures. One might have preferred to have the work installed in a busy central place in the new station rather than in an out-of-the-way place, but at least it was preserved where it can be freely admired by the public.

In the first weekend of November 2023, my colleague Amory Atkins and I attended dedication concerts of the rebuilt and reimagined 1977 Klais organ at Saint Peter’s Lutheran Church on Lexington Avenue (at the CitiCorp building) in Manhattan. I have written previously about the emergency removal of the organ a couple winters ago following a major water main break at the intersection of East Fifty-Fourth Street and Lexington Avenue. The lower levels of the church were profoundly flooded, and while there was only about a half inch of water in the organ, there was great concern about mold developing and the need to remove the organ quickly for remediation in the entire room.

There had been questions about the viability of the instrument for many years. It has an iconic case designed by Massimo Vignelli, but the windchests and mechanical action were problematic, the wind system was inadequate, and the tonal structure was substandard. The organ was shipped to the workshop of C. B. 
Fisk, Inc., in Gloucester, Massachusetts, where it was reworked with a new wind system and tracker action, several lovely replacement voices, and a general revoicing. The resulting instrument is a joy to hear. The preservation of the case and visual design of the organ was an important move, retaining the original architectural content of the striking and unusual sanctuary.

This project was a great example of how thoughtful changes can extend the life and improve the usefulness of an artwork. It is exciting to celebrate that organ’s rebirth concurrently with the installation of the restored and re-invigorated Lippold sculpture, Orpheus and Apollo. Neither project was a strict historical restoration, and both brought new life to important works of art through open-minded appraisal and thoughtful craftsmanship. There are a lot of ways to interpret the concept of historical preservation.

Someone had to do the dishes.

Wendy and I are empty nesters with four grown children between us, three of whom have families with children—our sixth grandchild is due in February. One of those families, with girls ages one and five, was with us last weekend for a rollicking visit. After a raucous and hilarious dinner, the evening before they left (grandpa’s grilled chicken legs with Za’atar were a big hit), mother, father, and grandmother went upstairs to supervise bath time, while I tackled the dishes. I connected my iPad to the Bluetooth speaker in the kitchen and started a favorite recording of mine, Joan Lippincott playing Bach sinfonias with orchestra (Gothic Records) on the beautiful organ with two manuals and twenty-nine stops built by Paul Fritts & Company (Opus 20) in the chapel of Princeton Theological Seminary. Joan presents a variety of Johann Sebastian Bach’s (1685–1750) instrumental movements with organ obbligato and orchestra imaginatively arranged into three-movement concertos.

The cheerful music filled the room as I loaded the dishwasher and packed leftovers (there would be a great lunch the next day), and I marveled anew at the mystery that is our music. These pieces were all written in Leipzig in 1726. Bach was in his early forties and at the top of his game, composing, arranging, rehearsing, and performing a new cantata every week. He played the elaborate organ parts on the three-manual organs in the churches of Saint Thomas and Saint Nicholas in Leipzig, miracle instruments that were the most complex devices of their day.

Organbuilders make intricate charts showing the math involved in making organ pipes with diameters halving at something like every seventeen notes resulting in parabolic lines of the tops of the pipes—all that mathematical precision was developed by Bach’s organbuilders and those who preceded them over the centuries. Eighteenth-century craftsmen made the grids for slider windchests, keyboards, casework, stop actions, key actions, and hand-pumped wind systems using hand tools to transform trees into the intricate and precise pieces and parts that make up any pipe organ. We marvel at all that today, the brilliant sounds and sophisticated tuning systems of instruments made with modern power tools. Bach played on organs with 16′ choruses, complex mixtures, and colorful reeds. The longest days for the people pumping the organ bellows must have been when the tuners were at work. It takes hours to tune a six- or seven-rank mixture with the stable and consistent air pressure from a modern organ blower. I can imagine the organ tuner in Leipzig in 1726 hollering at the pumping assistant to keep the pressure steady, hour after hour.

Put yourself in a pew as an eighteenth-century churchgoer, hearing the “world premiere” of a new Bach cantata every week. Maybe you recognized each as an astounding achievement, but maybe it never occurred to you that it was something special, that generations of succeeding musicians would admire and perform that music. Not to compare myself to Bach, but the oft-repeated comment in the narthex, “The music was great, as always,” seemed sometimes to ring a little false. Did parishioners at the Thomaskirche take their organist for granted?

We listen to performances and recordings of today’s finest players who set high standards of virtuosic musicianship. I wonder what Bach’s music sounded like as he played and conducted it. Were the violinists, oboists, bassoonists, and harpsichordists of Leipzig all brilliant players with pedagogy and techniques like what we are used to, or were they groups of local yokels aswim in the fantastic other-worldly, never-before-seen technical demands of the music of the local master?

Think of the coloratura fireworks of Bach’s Cantata 51, Jauchzet Gott in allen Landen. It is a lifetime achievement for a modern soprano to tackle and master that heap of notes. Was there a parishioner in Leipzig’s Thomaskirche who could toss it off? Maybe she had a couple kids who sang in the choir. I wonder if she had a day job. And do not forget the trumpet part in that piece—the high tessitura with patterns of repeated sixteenth notes to be played on a valveless eighteenth-century trumpet. Was that trumpet player a shopkeeper in real life? Maybe a cop, because he must have been able to whistle like crazy with that embouchure in his face.

There must have been local recognition that something special was going on. How else could the music produced by the local organist of a single church have been preserved and reproduced for the ages?

What were they really like?

Fifty years after Bach wrote those organ sinfonias, Wolfgang Amadeus Mozart’s (1756–1791) creative genius was defining the identity of the recently invented fortepiano. His sonatas and concertos were central to the introduction of the instrument into the musical mainstream. Most of Mozart’s music was performed in private salons and small public halls—at the time of his death in 1796, there were not many concert halls with more than 500 seats. I wonder what those evenings were like. Were people smoking and drinking while Mozart played? Were they talking? Was the piano well in tune? Were servants milling about offering snacks? The 1984 movie Amadeus portrayed Mozart as bawdy, rude, even vulgar. Do we suppose this was based on fact or legend? He was destitute toward the end of his life. Did he show up to play in a fancy drawing room wearing torn and dirty clothes? Did he stuff his pockets with those snacks because he did not have food at home? Did people forgive his unpleasant mannerisms because his music was sublime?

A generation after Mozart, Ludwig van Beethoven (1770–1827) helped transform the piano into a larger-scale concert instrument. As his keyboard technique was growing, he demanded more from the instruments on which he played, breaking strings and grousing about weak tone, once complaining to a piano technician that the instrument “sounded like a harp.” Nannette Streicher (1769–1822) and her brother inherited their father’s piano factory, and while the brother ran the business office, Nannette reengineered their pianos to keep up with the expectations of the burgeoning virtuosity of the day.¹ Friedrich Kalkbrenner (1785–1849) was reportedly the first artist to play lightning-fast passages of octaves in both hands, that technique that dazzles and confounds many organists. I can imagine the reaction of the piano technician witnessing that power on an early-nineteenth-century keyboard for the first time.

Nannette Streicher increased the range of the piano, adding octaves at each end of the keyboard. She increased the scale and tension of the strings, beefing up the internal structure to withstand the added pressure, and she developed a new form of keyboard action to propel the dampers toward the strings with greater force. She also built an 800-seat concert hall adjacent to the factory where Beethoven and other virtuosos performed, an important part of the passage from salon musicales toward what we know today as large public performances.

Nannette’s profound contributions to the development of the piano coincided with Beethoven’s advancing the art of playing and writing for the piano. I love imagining their interchanges. Did Beethoven visit her in the factory, looking over prototypes for new designs? It would have been fun to be a fly on the wall. Besides their professional relationship, Nannette was devoted to Beethoven personally, helping him organize his notoriously sloppy household and managing his scraggly finances. We read that he could be irascible, maybe nasty sometimes, but I suppose Nannette was patient and gentle with him. She was the epitome of the full-service piano technician, and she was a brilliant engineer in an age when women were seldom recognized for their professional acumen.

Warm in their PJs, and sent off to bed

Continuing with my after-dinner chores, I put on another of my favorite recordings, Camille Saint-Saëns’ (1835–1921) Second Piano Concerto in G Minor played by Jean-Philippe Collard with André Previn conducting. The second movement, “Allegro Scherzando,” gives insight into the witty, impish side of Saint-Saëns’ personality as it shifts back and forth between different themes and styles with moments of campy “boom-a-chick” rhythmic accompaniments. Remember, this is the guy who included a parody of pianists in Carnival of the Animals, poking fun at the drudgery of practicing scales. He plays another joke in Carnival, offering the nimble and subtle melodies of the “Scherzo” from Mendelssohn’s Midsummer Night’s Dream and Berlioz’s Dance of the Sylphes to be tromped on by the elephantine double basses of the orchestra.

There is a wonderful photograph of Saint-Saëns wearing a voluptuous pair of pajamas, standing on an elaborate carpet and surrounded by ornate decorations, including a bronze statue on a table behind him—it looks as though it might be Rodin. (You can easily find the photo by googling “Saint-Saëns pajamas.”) He is looking sideways out of his eyes, maybe a little suspiciously, as if he is surprised to be caught in his PJs. In his memoir, Recollections (Belwin-Mills, 1972), organist Marcel Dupré shares a few anecdotes about his personal encounters with Saint-Saëns, remembering him as kind and gentle. Studying the many photos and listening to his music, I imagine him as a lot of fun. There is a twinkle in his eye and a twinkle to his music that suggests he knew a good joke when he heard one.

Thinking of the parishioner at the Thomaskirche in Leipzig and wondering if she took for granted the world-altering music she heard every week reminds me of an anecdote told by Clyde Holloway during his tenure as professor at Indiana University as he took a group of students on a study trip to Paris. While the students were in the thrall of Marcel Dupré’s (1886–1971) brilliant improvisation, dazzled by the thrill of it, he noticed a woman sitting in a corner pew with her hands covering her ears. Curious, he went to her and asked if the music was bothering her. “Yes, it’s horrible, and it’s like this every week.”

Bath time is over, and the grown-ups are back in the kitchen for a nightcap and some more chat before bed. I’ll turn the music down now, but it has been fun wondering about the lives and personalities of some of my musical heroes as I cleaned up after dinner. I continue reflecting on the magic that is music. The arranging of musical notes in a certain order, the creation of harmonies by stacking notes above each other, and the progression of harmonies that propel a piece of music toward its conclusion seem other-worldly. The wide variety of instruments we have developed over centuries allows us to bring music to reality in time and space. It is easy to be baffled by the complexity of the organ, but consider the violin, a pound of carefully shaped wood and tensioned strings that can fill a concert hall with sound. Whose idea was all that? We might pay $5,000,000 for a forty-ton organ ($125,000 a ton) while a high-end violin can cost $15,000,000 ($937,500 an ounce). Which is the better value?

I recall my idol, Pythagoras, passing by a blacksmith shop on the Greek Island of Samos around 400 BC, noticing extra tones in the sounds of the anvils, what we know as overtones. His observation led to harmony and melody and the limitless collection of musical timbres we treasure today. But it was flawed mortals­­—Bach, Mozart, Beethoven, Saint-Saëns, and Dupré—who imagined the music and wrote it down for us to bring back to life.

Well done, good and faithful servant

Brian Jones, long-time director of music and organist at Trinity Church, Copley Square in Boston, Massachusetts, and conductor of the Dedham (Massachusetts) Choral Society, passed away on November 17, 2023, from complications from Parkinson’s disease. He was eighty years old. When I was finishing high school, my father took me to meet Brian for advice about where I should continue my organ playing education. Brian was a graduate of the Oberlin Conservatory of Music, and that is where I went. I was seventeen and he was thirty.

Brian was appointed to his position at Trinity in 1984 and served there until 2004 when he received his appointment as Emeritus Director of Music and Organist. During his tenure, the Trinity Choir achieved national recognition through the release of five recordings including the fabulously successful Candlelight Carols that sold hundreds of thousands of copies and raised the annual Christmas carol service at Trinity to a “must go, standing room only” celebration.

Brian’s twenty-seven-year tenure with the Dedham Choral Society saw the group’s membership increase from twenty-five to 150 singers. Their venues advanced from local church sanctuaries to performances of works like Verdi’s Requiem with full orchestra in Boston’s Symphony Hall. His giant personality and infectious love of music drew people to choirs he led and concerts he presented.

I worked with Brian at Trinity as organ curator for more than ten years starting in 1987. A large part of that work was tuning from 8:00 a.m. to 10:00 a.m. each Friday in preparation for the regular noontime organ recital. I would typically stay for the concert so I could join in the rollicking post-concert lunches at House of Siam, a superb Thai restaurant across Copley Square. Brian was the raconteur at those lunches, regaling the extended table with endless stories, sometimes bawdy, always hilarious. There were many scores of lunches, and I met countless brilliant and fascinating people. “Fridays at Trinity” was a rich education for me about the world of the organ, and Brian was the Dean, leading the laughter.

There were recording sessions scheduled for the wee hours to minimize the intrusion of city noises, and I was always present to correct short-term lapses in tuning or mechanical mishaps. One night, we were interrupted by an immense grating noise from outside just as Brian was starting a take. A machine with a toothed wheel twelve feet in diameter was gnawing a trench in Clarendon Street, and the recording engineer had enough cash in his pocket to convince the crew to keep quiet for the next hours.

The beautiful recording Carols for Choirs was originally produced in-house and was such a success that it would be rerecorded professionally for wider distribution. To make compact discs available for sale before the Christmas shopping season, the recording sessions were in July. It was horribly hot, and the sessions were in the middle of the night. The organ’s many reeds were built and voiced for sixty-eight degrees Fahrenheit, but as the church had no air conditioning, the sultry summer heat brought temperatures to the high nineties in the higher reaches of the organ, and it was not possible to raise the pitch of the reeds enough to match the pitch of the flues. Brian and I had some difficult conversations as I explained the permanent damage that might be caused to the historic, iconic organ pipes, and we experimented with altered registrations to find lovely sounds that were not compromised by the fractured off-season tuning. As the sessions progressed, I lay on the pews, dressed in shorts and t-shirt soaked with perspiration, listening to that superb choir singing the best music of Christmas in July, a treasured absurd memory in the life of an organ tuner.

In December of 2012 I brought a New York colleague to Boston to show him some of the city’s great organs, and we had dinner with Brian in a restaurant on Boylston Street. That afternoon I heard from my son that his wife had gone into labor with our first grandchild, and during the meal I received updates by text message. Ben was born as we were having our last sips as Brian shared stories about his grandchildren.

I am grateful to Brian for encouraging me to study at Oberlin, and I am grateful to him for all the shared experiences at Trinity Church. His friendship and influence were an important part of my appreciation and understanding of the music of the church, and his contributions to American church music seem endless. Rest well, good friend.

Michael McNeil

Michael McNeil has designed, constructed, voiced, and researched pipe organs since 1973. Stimulating work as a research engineer in magnetic recording paid the bills. He is working on his Opus 5, which explores how an understanding of the human sensitivity to the changes in sound can be used to increase emotional impact. Opus 5 includes double expression, a controllable wind dynamic, chorus phase shifting, and meantone. Stay tuned.

Many American organists have traveled to Europe and heard the sounds of older organs that make Bach a revelation. American organ building was for much of its history rooted in the Anglican tradition and the Romantic sounds of organbuilders like Ernest M. Skinner, and neither of those great art forms are an ideal medium for Bach. Tentative steps in the Anglican tradition were made as early as the 1930s to recreate this European sound, but they did not amount to a revelation. The revelation occurred with a British-born virtuoso, E. Power Biggs, who brought a sound to America that would convincingly play Bach in the form of an organ built by D. A. Flentrop. Biggs paid for this organ out of his own pocket and in 1958 found a home for it in the very reverberant acoustics of what was known at the time as the Busch Reisinger Museum.¹ His recordings of this Flentrop energized the budding Organ Reform Movement in the United States and inspired many American organbuilders. Listen to the end of the Fugue in A Minor, BWV 543ii <Soundclip 1>.

Dirk Andries Flentrop (1910–2003) worked in his father’s organbuilding shop and with Theodor Frobenius in Denmark, eventually taking over his father’s business. He was intensely interested in classical organ design, and he gave a lecture at a very young age in 1927 in which he promoted the use of mechanical action and slider windchests.² A conversation with Flentrop in the 1970s turned to his earlier career, and he recalled that he was traveling on a streetcar in Rotterdam when bombs started falling on that city in World War II. Everyone on the streetcar agreed there was no point in getting off, and they continued traveling to their destinations as bombs fell. The date was May 10, 1940, the year he took over his father’s business. I sailed with my parents on the SS Rotterdam in 1964 and still remember the shock of seeing upturned docks as we approached the harbor at Rotterdam and whole city blocks of uncleared rubble decades after the bombing.

Flentrop’s sound

The sound of pipe organs can be described subjectively and objectively. Subjectively, the sound of D. A. Flentrop is bright and “instrumental,” where individual pipes in the principal chorus have rich harmonic content. This is very different from what is today called vocale voicing, which emphasizes less harmonic power. Flentrop’s richly harmonic sound creates a scintillating principal chorus with clarity of pitch.

A key component of this sound, and a strong departure from the Romantic and Anglican traditions, is the expression of “chiff.” E. Power Biggs described chiff as the articulate “ictus” of a sound, adding clarity to rhythm and contrapuntal harmony. Chiff is not just percussive noise. It consists of higher natural harmonics to which the human ear is very sensitive, quickly defining the pitch. Flentrop was a master of this percussive speech, and it was always musical and fast. Chiff can be modulated with a sensitive mechanical action and low wind pressures (i.e., with little or no key pluck). Biggs was adept at this on his Flentrop, easing the pallets open for a smooth treble line while crisply opening the pallets to delineate inner voices with more chiff.

Later expressions of this articulation in what became known as neo-Baroque voicing are often heard as a slow, gulping sound. You never hear slow, gulping speech in a Flentrop organ, and as the data will show, Flentrop’s voicing exhibits no relationship to neo-Baroque voicing recipes.³

There is ample evidence that much of D. A. Flentrop’s sound is based on examination of the work of Arp Schnitger, and Schnitger’s sound is much more instrumental in character than modern vocale voicing. The similarity to Schnitger extends also to the design of the reeds, whose basses are the source of a smooth and powerful fundamental.

Flentrop organs have considerable presence, due in large part to the shallowness of the casework found in all of his organs. Flentrop related that the maximum depth of a case should be no deeper than the reach of an arm from the back doors of the case to its façade pipes. Deep cases and chambers will tend to absorb sound, especially the higher harmonics that create the sense of presence. I find it interesting that unaltered manual divisions of Cavaillé-Coll organs, while using higher pressures with Romantic scaling and voicing, almost never exceeded twelve stops and always used slider chests with mechanical action, reflecting some of the important design features of Flentrop organs.

The generosity of D. A. Flentrop

D. A. Flentrop was secure in his knowledge and very willing to share it. I was the recipient of his generosity on several occasions when he toured the United States with his senior voicer, Sijmen “Siem” Doot, to maintain and tune his organs. Doot, born in 1924, entered Flentrop’s service in 1939 and retired in 1988. Ed Lustig at Flentrop Orgelbouw confirmed that Franz Rietsch, Rob Oudejans, Johannes Steketee, and Doot assembled the Flentrop organ in Saint Mark’s Episcopal Cathedral, Seattle, Washington, in 1965, while Steketee and Doot remained to voice the organ. The voicing data in this article is a testament to their skill. I was introduced to Flentrop by Albert Campbell in 1971. After scouring the literature and finding mostly subjective opinions with very little data, I quickly discovered that Flentrop was genuinely interested in answering the detailed questions of a budding organbuilder. When I asked him if he would grant me permission to take measurements of his organs, he replied, “imitation is the finest form of flattery. Your ears will be different than mine, and you will use your observations to find your own sound.” He was right, but it took quite some time before I began to understand some of those observations, and the data continues to generate insights.

I again met Flentrop in the Campbell home after completion of my Opus 1, and by that time I had learned enough to ask deeper questions. Flentrop had nearly completed the tuning of his organ at the University of California, Santa Barbara, and in a further gesture of generosity, Flentrop said, “If you finish the cone tuning of the Hoofdwerk Mixtuur, we can answer your questions.” I agreed to finish the tuning work on the Flentrop organ, and both he and Mr. Doot spent the whole day answering my questions.

Flentrop slider windchests

D. A. Flentrop organs have exclusively featured mechanical key action and slider windchests since 1949. Stop actions were mechanical, as well, and only in his larger organs do we find electric slider motors and combination actions. Organbuilders who looked to the literature for the design principles of slider chests in the 1970s often found the effort frustrating. Flentrop willingly shared a great deal of his design practice. In Figure 1 we see a drawing made by the author from notes of a conversation with Flentrop regarding channel design. Flentrop recommended that the cross-sectional area of the key channel should have about 20–30% more area than the combined areas of all of the pipe toes it would need to wind. A small vent hole at the end of the channel served two functions—to prevent ciphering and to dampen resonances in the channel that would interfere with reeds. Reeds that are equal in length to the channel that feeds wind to them may get much louder, and those not quite equal to that length may get much weaker and more dull in timbre from channel resonance. I noted that the bottom of the key channels in the Flentrop organ at the University of California, Santa Barbara, were covered in a thick paper that had pin pricks in a few channels in various positions, likely done to reduce channel resonance.

Flentrop stated that pallets did not need to exceed 200 millimeters (about eight inches) in length, but I have found much longer pallets in Hook organs. I did not ask how to trade off key channel widths and heights for a given area, nor the flow areas of the pallets, and these tradeoffs can be complex. Suffice it to say that the flow area of a pallet is the length of its opening times the distance the pallet is pulled open by the key (an open pallet has a triangle of flow at each side, and when combined, these triangles make a rectangle). It is also interesting to note that a pallet will not flow significantly more wind to a channel when its pull is more than half of the channel width (think about the height of those triangles that flow wind relative to the width of the channel). For a given pallet pull and a key channel width that is twice the pull, only a longer pallet will flow more wind to the channel.

The 1863 Hook organ at the former Church of the Immaculate Conception in Boston, Massachusetts, has roughly 460-millimeters-long pallets feeding 406-millimeters-long flue and reed channel openings in the Great bass octave (there are two pallets per note). The Romantic voicing of the Hook organ requires a very large volume of wind to feed its very deep flueways and very widely opened toes, which are much larger than Flentrop’s. At Saint Mark’s, Flentrop likewise used two pallets for the six bass notes of the Hoofdwerk, with pallet opening lengths of 155 millimeters, flue and reed channel widths of 21 millimeters and 17 millimeters, respectively, and a channel height of 79 millimeters. Readers who are interested in comparing the differences in the voicing of Flentrop and Hook organs can find the Hook data in The Diapason.⁴

Flentrop’s patented slider

Slider windchests in ancient organs often suffered from the advent of central heating. Topboard bearers are shimmed with layers of paper for a close fit between the slider, the windchest table on which it rests, and the topboard above it. With central heating and the resulting low humidity, shrinking wood caused these sliders to leak wind and impair the tuning. Many different forms of slider seals were invented in the twentieth century, most of which worked quite well. Flentrop’s system is patented and rather complex, but it is extremely reliable. Flentrop used two sliders, separated by springs with a leather-faced conduit for the wind between the two sliders. Figure 2 (see page 15) shows this slider seal mechanism in relation to the pallets, key channels, and topboards.

An objective approach to Flentrop’s sound

If you want to discover how to achieve a certain sound, it is often educational to closely observe the organs you like and those you do not. The objective differences will teach you what matters. Readers who want some perspective on the following Flentrop data will find a description of the voicing of several historic organs in The Diapason.⁵

The absolute minimum data needed to understand the sound of an organ is:

• pipe diameters (inside);

• mouth widths;

• toe diameters;

• mouth heights (also known as “cutups”)

• flueway depths.

Complete descriptions of these parameters can be found in the article mentioned above.⁶ In a nutshell, larger pipe diameters, wider mouth widths, larger toe diameters, and deeper flueways yield more power. Mouth heights control timbre, and higher mouths reduce harmonic power and brightness. Flutes typically have much higher mouths than more harmonically rich principals.

Wider scales produce an “ah” timbre, and narrower scales will progress towards an “ee” timbre, emphasizing higher harmonics. Flentrop stated that he used a constant scale of pipe diameters and mouth widths for the principal chorus in most environments and acoustics, which meant that he wanted a specific vowel timbre for all of the pipes at the same pitch and a specific power balance across the range of frequencies from bass to treble.

For different acoustics Flentrop used different pressures and voicing, adjusting the toe diameters and cutups. Ascending trebles were achieved in the toe diameters. Figure 3 shows Flentrop’s chorus scaling written in his own hand in 1971 with numerical values he had memorized.

Flentrop reeds were often made by the firm of Giesecke to Flentrop’s specifications. A description of the data needed to understand the sound of a reed can be found in an article in The Diapason.⁷ The author’s measurements of the Saint Mark’s reeds were not taken in sufficient detail to merit showing them. Flentrop reed designs are very similar to Schnitger’s and use tin-lead plates with restricted openings soldered to wide, lightly tapered, and deeply cut shallots for powerful, smooth basses. These typically transition to open, parallel shallots without plates in the tenor.

Taking the data at Saint Mark’s

I have been fortunate that many of those who are a gate to the access to some important organs have granted me permission to measure them. In 1972 that good fortune allowed me to take measurements of Flentrop’s organ at Saint Mark’s Episcopal Cathedral, Seattle, Washington, the organ Flentrop considered his largest by virtue of its 32′ façade pipes. The stoplist of the Saint Mark’s organ is easily found on the internet.⁸

The cathedral measures an estimated 150 feet in length and width, with a flat, wooden ceiling about 90 feet high. The walls are very thick concrete, yielding an acoustical reverberation of about five plainly audible seconds in the soprano range.⁹ The reverberation drops dramatically in the tenor and bass as a consequence of the very large windows, through which the lower frequencies easily pass.

Richard Frickmann, a life-long friend, and I drove over a thousand miles to visit this organ, and upon arrival in the early morning we sat in the pews in the empty cathedral, looking back at the organ. Glenn White, who maintained the organ, noticed our interest in this magnificent Flentrop and struck up a conversation. Learning that we were eager to find scaling data of the pipes, he questioned us for about five minutes and admitted that no one had taken the time to measure the pipework. He took us to the office and gave us the keys to the Flentrop casework, the organ loft, and the cathedral, asking that we return them when we were done. This was a stunning opportunity and one rarely offered. Mr. Frickmann and I took over fifty pages of data, interspersed with trips to the local twenty-four-hour pancake house to refuel with food and coffee. I had brought with me copies of scaling sheets and measuring tools, and Mr. Frickmann wrote down the numbers as I called them out from the walkways behind the windchests. After about twenty-four continuous hours of work, we handed in the keys to the office.

A word of caution on the data is in order. I took this data in 1972, very early in my career. I had experience with Flentrop’s organ at the University of California at Santa Barbara, and I understood basic scaling and data collection. But what I did not yet appreciate at the time was the importance of measuring the depth of the flueway. My general observations of the flueways of the Saint Mark’s organ were that “they tend to be consistent throughout the organ relative to pitch, much wider than current neo-Baroque work, but narrower than the voicing of the early American builders like Johnson and the Hooks.” Later measurements of Flentrop flueways provided a generalized model of the flueways for the Saint Mark’s organ. Please be aware that these are probably in the ballpark, but they are assumptions.

I was very careful in the handling of the pipes and making sure that their mouths faced in their original directions (this affects tuning on larger pipes whose mouths can be close to other pipes and shaded by them, lowering their pitch). The measurements of these pipes will have some inaccuracy from the time constraints. For larger pipes the measurements are likely better than +/- 1 millimeter, and for the very smallest pipes, about +/- 0.2 millimeter. The data is presented in halftone deviations from Normal Scale to make the relationships clear, as tables of numbers do not easily convey their meaning. These Normal Scales were published in the author’s article, “1863 E. & G. G. Hook Opus 322: Church of the Immaculate Conception, Boston, Massachusetts,” Part 1.¹⁰ Those who want actual measurements can use those tables to convert the Normal Scale data into dimensions, or they can email the author for a copy of the Excel spreadsheet with the more accurate raw dimensional data.¹¹

The Hoofdwerk

Larger pipe diameters generate more power, and smaller diameters generate a brighter timbre. Flentrop’s principal chorus scales combine these factors into the sound he wanted. His scaling model in Figure 3 is seen as a dashed blue line in Figure 4. The model generally follows the Saint Mark’s data. As Flentrop noted, the mixtures are narrower. Flutes trend much wider as the pitch ascends.

Sound clips of the Saint Mark’s Flentrop in the digital edition of this article allow one to hear these power and timbre balances. They were derived from 1981 recordings of James Welch, organist, another life-long friend. The recording engineer, Dave Wilson, was known as one of the world’s best, and he recorded Welch on Flentrop organs. I was present in 1981 for the Saint Mark’s recordings, mostly to help with touching up the tuning of the reeds. I also made suggestions for stop registrations that ran counter to the prevailing wisdom of the time, dictating a minimal use of foundations to aid in clarity of pitch. This was not necessary on a Flentrop, whose foundations can be combined to any degree and still maintain clarity of pitch. Amassing foundations, as any Romantic organist knows well, is a source of rich chorus depth, and it is heard to great effect in Charles-Marie Widor’s “Andante cantabile” from Symphonie IV in <Soundclip 2>.

We made many experiments with microphone placement. The proper power balances of the different Flentrop divisions were finally achieved by placing microphones on very tall stands about twenty to thirty feet in front of the Rugwerk, the division that has the most presence for the congregation. Having been accustomed to the practice of using fast tempos in dry acoustics, Welch and I discussed appropriate tempos for the reverberant acoustic of Saint Mark’s. Borrowing headphones from the recording engineer to hear what the sound was like in the room at the microphones, he arrived at the tempo we hear in C. P. E. Bach’s Toccata and Fugue in D Minor, which takes full advantage of Saint Mark’s long reverberation <Soundclip 3>.

Late in the all-night recording session a note went dead in the Rugwerk. The organ had been in service for only sixteen years at this time, and a failure was unexpected. I pulled up the floor panels in the choir loft, which gave access to the Rugwerk trackers, and the culprit was a torn piece of weak leather that connected a long horizontal tracker at a suspension point. None of the other connectors showed the slightest sign of wear. I made a temporary fix, adjusted the action, and we continued recording well into the next morning.

Figure 5 shows the scales of the mouth widths, and these generally imitate the diameter scales. Normal Scale mouth widths are based on 1⁄4 of the circumferences of Normal Scale diameters, and as Flentrop almost exclusively used 1⁄4 mouths, we would expect a similarity to the diameter scales. Some of these mouth widths appear to be a bit wider than 1⁄4 of the circumference, and this may indicate that the pipes were slightly tapered, something I did not measure, and which is not uncommon. Inside diameters were measured at the top of the pipes. If the pipes have a slight taper, the true diameter scales at the bottom will be larger and will more closely match the Flentrop model in Figure 4, as well as the mouth scales in Figure 5.

Figure 6 shows mouth heights, or what is more commonly known as “cutups.” The cutup controls timbre. A higher mouth will reduce the harmonic content, and smooth flutes have higher cutups. These can be clearly seen in the lofty cutups of the 8′ Roerfluit. Normal Scale mouth heights are calculated as 1⁄4 of the Normal Scale Mouth Width, a common recipe in neo-Baroque voicing. In Figure 6 we see that Flentrop did not use this recipe. The Saint Mark’s cutups are much higher, and they have no relationship to the mouth width scales. They are also highly variable as a free voicing parameter. Flentrop raised the cutup until the desired timbre was achieved and the speech was fast. This is why you do not hear slow, gulping speech in a Flentrop organ.

The soaring cutups of the Roerfluit

The soaring cutups of the 8′ Roerfluit illustrate how Flentrop achieved a rich harmonic timbre in his principal chorus and a smoother, warmer timbre in the flutes. While Flentrop is noted for a brighter, “instrumental” timbre, which strongly implies lower cutups, Figure 6 clearly shows that his cutups were much higher than the neo-Baroque recipe. As an example, the cutup of the 8′ Roerfluit tenor C pipe in Figure 6 is +5 halftones, while its mouth width in Figure 5 is -5 halftones, revealing a cutup that is a stunning 10 halftones higher than the neo-Baroque recipe.

Figure 7 (see page 18) shows the relative flow of wind in the pipe toes. Larger pipe toes will flow more wind and yield more power. Received wisdom relates that Flentrop used “open toe” voicing, but Flentrop toes are in most cases quite restricted. Much more open toes can be found in Hook organs. Hook toe diameters also have high variability at a specific pitch, very unlike the more regular wind flow patterns we see with D. A. Flentrop and Gottfried Silbermann.¹³

The values in Figure 7 are toe constants, a number that represents relative flow. Flentrop suggested to me that a reasonable starting point for a toe diameter is the square root of its resonator diameter. The area of that closed toe represents a constant of “1,” and as you can see in Figure 7, Flentrop converged on that number at about 1′ pitch and increased the flow in both deeper and higher pitches. The area of the toe is proportional to the toe constant, i.e., a toe constant of “2” has twice the area of a toe with a constant of “1.” One added feature is that the toe constant compensates for mouths that are wider or narrower than the Normal Scale mouth of 1⁄4 of the circumference. For Flentrop this does not matter, because he used 1⁄4 mouths, but for a builder like Gottfried Silbermann who used 2⁄7 mouths, or Ernest M. Skinner who used 1⁄5 mouths, this compensation is critical, because wider mouths need more wind and narrower mouths need less. The toe constant allows us to compare the relative flow of wind in pipes with different diameters and different mouth widths. A good example in Figure 7 is the 8′ Roerfluit, which has slightly more wind than the 8′ Octaaf. Although it has a much smoother timbre, the 8′ Roerfluit’s slightly more powerful fundamental adds chorus depth to the much brighter 8′ Octaaf.

Toes control power, and in Flentrop organs designed for smaller acoustics I have found toe constants of 0.6 in the lowest mixture pitches, and this is a very restricted toe. A fully open toe has a toe constant of about 4, which we see in the highest pitches of the 2′ Octaaf and III Scherp in Figure 7.

Note the consistency of wind flow in the Flentrop principal chorus pipes at a given pitch, with a minimum flow of wind at about 1′ in pitch and much more flow in the bass and treble. This represents a voicing model for the Saint Mark’s acoustic. Similar patterns of wind flow exist in the 1692 Schnitger organ in the Hamburg Jacobikirche.¹⁴

The wind flow of the 4′ Speelfluit in Figure 7 is very instructive. Its lower cutups, relative to the 8′ Roerfluit, are explained by its more restricted toes. Closing the toe has the tonal effect of raising the cutup for a much warmer timbre at a lower power. The Speelfluit adds color to the more powerful Roerfluit, while restraining the power of the combined flutes as accompanimental stops.

Figure 8 data are estimated flueway depths based on observation of other work by Flentrop. In 1972 I did not have tapered wedges for measuring flueway depths. Wooden wedges are the safest material for documentation, but for a voicer, brass or steel wedges will last longer.¹⁵ The important feature of Flentrop flueways is that they are not used as a primary means of controlling power. Flentrop flueways do vary, but they vary within a restricted range at a given pitch. Neo-Baroque voicing emphasized a cutup recipe set to 1⁄4 of the mouth width with “open toes.” The result was that a voicer was often forced to use very narrow flueways to regulate both power and timbre, and the resulting sound was typically thin in fundamental warmth with a slow, gulping speech on the verge of overblowing. Flentrop used wind pressures and toes to control power, not the flueways, and he adjusted the cutup to achieve the desired timbres with fast speech.

In both modern and ancient work we will find an enormous variation in flueway depths. Although it is very rarely measured, flueway depth is of critical importance in understanding the different sounds of pipe organs. As the flueway deepens, more breathiness is heard in the sound. This is corrected by an increasing amount and boldness of nicking as the flueway depth increases. This is one of the reasons you will find many bold nicks in deep Romantic flueways. Flentrop’s voicing finds the flueway depth that will yield a tolerable breathiness with a minimum degree of nicking, and this is the optimum point for chiff. This is not a deep flueway, but it is much deeper than the razor-thin neo-Baroque flueways that resulted from arbitrarily low cutups. Both Andreas and Gottfried Silbermann used much deeper flueways than Flentrop, and their milder chiff is the result of their bolder nicking. Readers can find the flueway depths for some important historical styles in The Diapason.¹⁶

Figure 9 shows what happens when we divide the area of the pipe toe (the radius of the toe, squared, times π) by the area of the flueway it feeds (the flueway depth times the mouth width). In Figure 9 we see this data as a ratio of those areas. This tells us a great deal about the speech onset of the pipes. If the pipe toe is closed to the point where its area is less than the flueway area, the pressure will drop in both the foot and the flueway.¹⁷ We often see this in organs with higher wind pressures where the toes are strongly reduced to control power. In this situation, however, not only does the pressure drop at the flueway, the buildup of pressure in the foot is slower, and this can lead to slower speech. This form of slower speech is not immediately obvious, but a chorus with ratios above 1.0 will have a prompt attack, while pipes with ratios of 0.5 will have a noticeably slower attack, as is often heard in the smooth solo voice of the classical French cornet.¹⁸ When we look at theatre organs with extremely high wind pressures and deep Romantic flueways, we also find extremely small toes that produce ratios well below 0.5. This is why the attack of theatre organ flue pipes is much slower than what we hear in a Flentrop.

Ultra-low area ratios also explain in part why theatre organ pipes never have chiff. A fast rise in pressure in the foot and flueway is essential to the production of chiff, and we hear this when Biggs crisply opens the pallets on his 1958 Flentrop. Ratios close to 1 or above will be conducive to a fast pressure rise and the production of chiff, and in Figure 9 we can see that no Flentrop pipes have values below 1, and most pipes have values well above 1. This is a feature of Flentrop voicing in all of his organs for which I have data, and it is a significant factor in Flentrop’s fast, articulate voicing. Flentrop flueways are not deep in the Romantic style, and their areas are relatively small, with the result that even Flentrop’s more restricted toes still supply much more wind than the flueways need, and the fast pressure rise produces chiff.

Chiff can be eliminated in any ratio of toe and flueway areas by simply applying many bold nicks, but Flentrop used nicking sparingly, and when it is used, it is typically very fine in nature. Hook voicing also features relatively high area ratios, but the voicers used many bold nicks on every pipe, and no chiff is audible in their voicing. Theatre organs combine ultra-low area ratios with very bold nicking and unsurprisingly never exhibit chiff.

Figure 10 shows the mouth of a Flentrop pipe from about 1980, which is articulate, even with its two bolder nicks. The finest nicking in the center of the languid is more typical of the Saint Mark’s organ. Note that the flueway, while not deeply open in the Romantic style, is much deeper than typical neo- Baroque voicing.

The Pedaal

Figure 11 shows the diameter scales of the Pedaal. The scales of the larger pipes are consistent with the Flentrop model in Figure 3, and the diameters of the larger pipes were measured at the bottom. The Mixtuur is also consistent with the model notes. Like the Hoofdwerk, the flutes trend much wider as the pitch ascends.

The wind pressure of the Hoofdwerk is 80 millimeters, which is interestingly the same pressure found in the restored 1692 Hamburg Jacobikirche Schnitger. All other divisions at Saint Mark’s are winded on a very modest 68 millimeters of pressure, including the Pedaal. Flentrop once commented that wind pressure in a pipe organ is analogous to the tension of strings on a violin, with similar effects in the sound.

When I visited in 1972, the 32′ Prestant featured large ears at the sides of the mouths, and a few years later I observed that large wooden rollers had been added between the ears. This was perhaps an effort to make the 32′ sound more audible, as human hearing is very poor in the deep bass. At about 20 cycles per second we feel sound as much as we hear it, and a 32′ pipe resonates at 16 cycles per second. The addition of the rollers increases audible harmonic power to the sound, just as they add harmonic power to very narrow string pipes. Joseph Gabler found an elegant solution to this problem in his organ of 1750 at Weingarten: drawing the 32′ stop also draws the 16′ stop at the same time, making the sound both felt and more easily heard.

Tin was very expensive when Saint Mark’s Flentrop was constructed, the result of a powerful tin mining cartel. Many Flentrop organs utilized copper for larger façade pipes during this time as an alternative to zinc. The colorful patina on Flentrop copper pipes exhibits reddish earth tones and subtle greens. I asked Flentrop how he achieved this, and he laughed. The process was the result of long experimentation, and it involved strongly heating the pipes and applying the urine of cows to the heated metal. Flentrop smiled when he said that the smell in the shop was not at all pleasant. The lovely pastel colors of those copper pipes enhance the deep reds of the mahogany used in the casework, which Flentrop carefully selected from his supplier in Africa.

The full principal chorus of Flentrop’s magnum opus in its 1981 configuration is electrifying in the Praeludium in E Major by Vincent Lübeck <Soundclip 4>. The organ today features some wonderful additions by the shop of Paul Fritts.¹⁹

Paul Fritts and Company Organ Builders

Additions and changes to pipe organs can result in irreparable harm to the original sound. The additions and changes by the Fritts shop, however, are sympathetic to Flentrop’s original concept. They are exceedingly well executed, and Flentrop’s original voicing was left unchanged.²⁰

In 1991 the console action was replaced with a suspended action. Germanic reeds were added at 16′ and 8′ to the Hoofdwerk, and the horizontal reeds were replaced at their original pitches with designs based on the 1762 work of the Iberian organbuilder Jordi Bosch. The original Flentrop reeds have been carefully packed and stored. The addition of a 32′ Pedaal Bazuin on the back wall to the rear of the Pedaal casework is a welcome one in a room whose large windows consume a great deal of bass sound. These alterations will hopefully diminish future appetites for changes to Flentrop’s historic magnum opus.

The precarious life of historic sounds

D. A. Flentrop’s organs are probably a very good representation of the sound of Arp Schnitger, which has very rarely if ever survived in its original form. Between 1953 and 1955 Flentrop undertook a major restoration of the 1720 Schnitger organ at Saint Michael’s Kerk in Zwolle to return it to its original condition, and Biggs recorded that magnificent sound in the 1960s.²¹ History teaches us that original sounds only survive in the very rarest of circumstances, and these are often found in depressed economies where there is no funding for restorations. Historically important sounds quickly disappear with the good intentions of restorers who change wind pressures, temperaments, pitch, and voicing to suit their own ears.²² This is why early documentation is so important, and it can expose later changes.

This article features a sample of scaling and voicing data from D. A. Flentrop’s magnum opus taken in its original form in 1972.²³ It has hopefully provided readers with a better appreciation of the sound of D. A. Flentrop. Astute readers will also no doubt notice that fifty-one years elapsed before I carefully analyzed this data. I should have done this long ago. Tempus fugit, carpe diem.

Youthful fantasies

Saint John’s Episcopal Church in Westwood, Massachusetts, was founded as a mission in September 1953, and services were first held in the Deerfield Elementary School at the end of Deerfield Avenue. A new church building was dedicated next to the school in March 1955, and my father was appointed the first full-time rector in October 1956. I was seven months old. We lived in a rented house nearby while the rectory was built adjacent to the church. I know from personal memory and family lore that we were ensconced in the new rectory before I was two years old. My earliest memories of those days included the bulldozers that were grading the lawn and building the driveway. My wife and sons would quickly agree that must have been the genesis of my fascination with heavy equipment, admittedly alive and well today as my sixty-eighth 
birthday approaches.

The Convention of the Episcopal Diocese of Massachusetts established Saint John’s as a parish in 1959, and that year the church acquired C. B. Fisk Opus 31 (then the Andover Organ Company), a one-manual, six-stop, mechanical-action organ mounted on a platform with a detached, reversed console. I learned later (!) that the organ was planned as the Rückpositiv of a larger two-manual instrument that could be completed if the new parish succeeded. At three years old, I did not yet know about detached consoles, but my child’s eyes remember where it was placed in the simple new A-frame building, itself designed to accept future enhancement.

Ten years after its founding, the parish mounted a campaign to build a parish hall and complete the church interior with formal decorations and furniture. Two towers and a rear gallery were added. A full-height stained-glass wall was installed behind the altar, a chancel with steps and altar rail was added, and hardwood pews were installed replacing the metal folding chairs.

Having spent a lifetime moving pipe organs, I am amused by the memory of my first organ relocation—that tiny Fisk organ hanging from a crane, pipes and all, being lifted from the front of the original sanctuary to its permanent home in the new rear gallery before the roof was closed. If I saw that happening today, I would run toward the crane operator, arms waving like a semaphore, shouting “Stop!,” but there it was, an organ hanging from a hook on a sunny day. I was seven. That same year, when my parents were not at home, I thought it would be fun to climb the scaffolding surrounding the seventy-foot tower under construction. It was a lovely view from the top, showing my parents’ car turning on to Deerfield Avenue, heading home. I got back down before they reached the driveway, but the guilt on my face was enough to spill the story.

Saint John’s organist’s name was Donald McFeely. He had the parish on the cusp of the tracker revolution, buying an organ from Charles Fisk and the Andover Organ Company before the founding of C. B. Fisk, Inc., in 1961. The Andover Organ Company completed the twenty-three-rank instrument in 1991, including the original six-stop organ as the Rückpositiv as planned by Charlie Fisk.

I remember several of the families of Saint John’s as friends of my parents, and as I write I realize what a heady time that was for them. It must have been thrilling to start with meetings to incorporate a mission, transforming it to a parish, and taking on two building programs in ten years. Through their commitment, effort, and money, they created a church that continues to thrive over seventy years later. My father was a young priest in his second appointment, and it must have been mind-boggling and life-altering for him to be at the helm of that rocket ship. Dad has been gone almost ten years, so I will never get to chat about that with him, but the notion adds to my admiration. By the way, I attended the Deerfield School, next door to our house, from first through third grades.

§

Since my first organ was a quasi-experimental dip into the early years of the Organ Reform Movement, it is ironic that the second organ in my life was built in 1905 by the Ernest M. Skinner Company at a time when Robert Hope-Jones (who grew into the genius behind theatre organs built by Wurlitzer) was working with Skinner. Dad was called as rector of the Parish of the Epiphany in Winchester, Massachusetts, in 1966, when I was ten years old. I was instantly pressed into the Junior Choir led by harpsichord builder Carl Fudge, the parish’s organist and choirmaster. As I think about it, the further irony is that Mr. Fudge as an early practitioner in the esoteric world of harpsichord building in the 1960s was saddled with an aging, wheezing, cadaver of an organ in such poor condition that my friends and I as ten-year-old choristers where well aware of its precarious state.

There was the Sunday when I heard my first cipher in the middle of a service. Mr. Fudge left the bench, crossed the chancel, reverenced the altar, returned with a ladder, reverenced the altar again, set the ladder against the impost, climbed up and pulled a pipe. He repeated the process to return the ladder, reverencing the altar twice more, wearing a black cassock through the entire sequence. I expect that his pious performance as the service progressed was calculated to draw attention to the organ’s failings, and it was only five or six years later that my father was involved in purchasing another organ from Charles Fisk, Opus 65, which was completed in 1973.

When I was twelve, I had my first organ lessons on the gleaming ten-year-old, three-manual Holtkamp organ in Saint John’s Chapel of the Episcopal Theological School (ETS) in Harvard Square, later the Episcopal Divinity School (EDS), now defunct. Though it has electro-pneumatic action, that organ was in the vanguard of experimental design with low wind pressures, classical choruses, and a Rückpositiv division (on a pitman chest) along the gallery rail. But my first experiences playing the organ during worship were on that home Skinner when Mr. Fudge allowed me to “noodle” a bit while he left the bench to receive communion, and later to play an occasional prelude or postlude.

It was not long before I went out on my own, taking a six-week gig playing on a three-manual Estey (long gone) at the Baptist church in Winchester, and then after Vatican II at St. Eulalia Catholic Church in Winchester on a Conn Artist. (You can’t make these things up.) My last high-school church organist position was at the First Congregational Church of neighboring Woburn, Massachusetts, where I played a three-manual, thirty-three-stop E. & G. G. Hook organ built in 1860, a very grand organ with real large-organ stops like 16′ Double Open Wood and 16′ Trombone with wood resonators.

Nostalgia

I am wallowing in childhood memories today because Wendy and I recently moved from Greenwich Village to Stockbridge, Massachusetts, where my grandfather had been rector of Saint Paul’s Episcopal Church, just at the time when my family moved from Westwood to Winchester and I started to take organ lessons. It has been both fun and eerie to merge into life in Stockbridge, walking past the rectory on Main Street where my grandparents lived, counting the windows, and remembering the rooms that were so familiar when I was a teenager.

Saint Paul’s first building was a wood Gothic structure designed by Richard Upjohn and consecrated in 1844. The present stone building was designed by Charles McKim and consecrated in 1884. The organ was Hilborne Roosevelt’s Opus 127, also built in 1884, but it was drastically altered in the early-1960s, a project that included the addition of mixtures and mutations, the replacement of the original principal stops with ranks of tapered pipes, the addition of a pedal division and a couple unified reeds including a Krummhorn with electric action. I wonder if Hilborne Roosevelt ever heard a Krummhorn? Today I call it a scandalous treatment of a lovely venerable instrument, but when I was twelve and thirteen years old and allowed to practice on the organ, loud and shrill as it was, I thought it was the bees’ knees. I do not remember if I ever played a service there, but I know I played a recital or two—I’m sure my grandparents were very proud.

When I was a kid, we had family holidays in Stockbridge. Thanksgiving dinner in the rectory was a great treat, and my grandparents nurtured my nascent love of music by treating me to weekends at Tanglewood, just a few miles away. Those were my first solo trips away from home—my parents put me on buses and trains in Boston and grandparents picked me up in Pittsfield, Massachusetts, quite an adventure for a thirteen-year-old.

Since I retired as a church organist when I joined the Organ Clearing House in 2000, we have not attended church regularly, but when we first moved to Stockbridge, we were quick to show up at Saint Paul’s. We went to the early service at 8:00 a.m. and were part of a congregation of five or six people. It was fun to meet a woman whose wedding had been performed by my grandfather and who had wonderful memories of him, but it was a pretty quiet affair. Shortly after, we learned that the rector had just received a call to move elsewhere, and after our first visit we went dormant.

A new rector was installed at Saint Paul’s eight weeks ago, and Wendy and I went to church there last Sunday, attending the 10:00 a.m. service along with more than forty others. It was great to hear the organ being played, though it is in terrible condition, and we were pleased with the good vibes, the singing of the hymns, and the fact that there were some people present who were younger than us. Maybe we will go back this time.

Altered states

I imagine we are all familiar with organs that have been altered, receiving new identities for better or for worse. Some are great successes. There are many organs built by the Skinner Organ Company and later modified by Aeolian-Skinner under G. Donald Harrison’s direction. Ernest Skinner hated that, but Harrison was able in many cases to retain the gravitas of the original organ while adding well-balanced choruses and mutations.

I had a long relationship with a 1906 Hutchings-Votey organ rebuilt by Kinzey-Angerstein in 1973 at Saint Mary’s Catholic Church in Holliston, Massachusetts. I joined the reorganized workshop of Angerstein & Associates in 1984, and the organ at Saint Mary’s was one of the first I tuned after taking that job. The occasion was a recital by Daniel Roth, then titulaire of Saint-Sulpice in Paris, celebrating the appointment of Saint Mary’s longtime organist, Leo Abbott, as director of music for the Cathedral of the Holy Cross in Boston and the end of his tenure at Saint Mary’s. The organ retained its original 8′ and 4′ principals, wood flutes, manual reeds, and pedal stops. Daniel Angerstein had added upperwork to the Great and Swell creating two fine choruses and a smashing 16′ Pedal Trombone. It is a grand organ with lots of pizzazz, and the new tonal scheme added wonderfully to the original foundation of the organ.

The Holliston organ was so successful because the new stops were scaled and voiced to complete choruses based on the original foundations. The added pipes were purposefully constructed to exacting specifications based on the scales of the original stops, so all voices blend as if the entire instrument had been built at once. Too often, organ technicians of lesser skill add voices to an organ based on the notion of an ideal stoplist without considering the scales, construction, or even wind pressures of the new pipes.

Earlier this year I visited an organ in Texas that has small-scale Baroque choruses added in the 1960s to a nineteenth-century organ with broad scales and heavy fundamental tone. The differences in harmonic structure between old and newer pipes is striking. The tonal effect is jarring, confusing, and difficult to sing with. The firm that added the high-pitched stops must not have made any effort to create a blend between old and new. The stoplist looks fine, but the organ sounds terrible.

When the revival of classic organbuilding was getting traction in the early 1960s, many of the new organs were focused on high-pitched voices as were the “Baroque-izations” of older organs. It is ironic because the great classical instruments of Europe on which our revival was based are typically not shrill instruments. Their stoplists show fully developed choruses crowned with multiple mixtures, but their foundation stops are rich and full with thrilling harmonic development to support all that upperwork. When twentieth-century organbuilders began building new mechanical-action organs with low wind pressure and open-toe voicing, the challenge they faced, whether they knew it or not, was to figure out to deliver lots of air, not pressure but volume, to the largest pipes in the organ, and to voice those pipes so they could really sing.

§

It is fun to think about the first organs I knew, how my youthful impressions compared to my current thinking after playing, working on, and listening to hundreds of organs. As a thirteen-year-old, I was enthralled by the idea that I could play music on those keyboards and fill a church building with sound. I have been around organs with serious intent for about fifty-six years, and the evolution of my understanding of organ tone is still in process. I have learned slowly how scale (diameter) and wind pressure affect what an organ pipe can do. I have learned how the shape of a pipe’s resonator (the long part) affects the harmonic structure of its tone, so it stands to reason that two stops that emphasize the same harmonics will blend well together—that is a simple glimpse of the complex structure of a Cornet, especially when a reed stop is added to it. (Think d’Aquin noëls.)

I sat in a pew at Saint Paul’s last Sunday, delighted that the organ was being played, but critical of its collection of unrelated stops, however much I enjoyed playing it fifty-six years ago. (Oof!) The church has had some hard times over all those years, but it is fun to think that we might breathe some new life into it. Wendy and I live a fifteen-minute walk from Saint Paul’s. Maybe I could help?

There have been many organs in my life that were altered from their original state and transformed into something different. Some are marvelous successes, some are unmitigated disasters, and some (perhaps most) are the transformation of a fine instrument into one that is mediocre and uninteresting. A well-intentioned local organ technician may have terrific skills, but may not have the knowledge, wisdom, and experience to “out-Skinner Skinner.” If the organ you play most regularly does not have a trumpet, you probably could add one, but it should be as close as possible to the trumpet the original builder would have included if the organ was to be one stop larger. The added stop must be heard as part of the original organ and not as irrelevant braying. It is not the stoplist that makes an organ, it is the tonal structure.

I was at dinner recently with two beloved and admired colleagues who are collaborating on an important new organ. I asked them what they hoped to achieve with that organ. One replied, “I want to make an organ that sounds beautiful so lots of people will be happy to hear it.”

Introduction

For this article, the fifth in a series on improvisation featuring interviews with American improvisers, we turn to Patrick Scott. Patrick won first prize and audience prize in the American Guild of Organists National Competition in Organ Improvisation (NCOI) in 2014 and is a member of The Diapason’s 20 under 30 class of 2016. Following numerous other distinguished positions, he presently serves as director of music and organist at Grace-St. Luke’s Episcopal Church in Memphis, Tennessee.

Very early in the summer of 2023 I stumbled upon one of Patrick’s improvisation recordings. I was struck by a compelling balance of creativity, originality, and organization. His structure was abundantly clear. A few weeks later, I saw Patrick at the national conference of the Association of Anglican Musicians in Dallas, Texas, and told him how much and why I had enjoyed his recording. “That was all Gerre [Hancock],” he said, ascribing the structure in his improvisation to his legendary teacher at the University of Texas. I wasn’t surprised, knowing that Hancock was a masterful pedagogue and having had one terrific, lengthy lesson with him myself many years ago. Patrick was among his last students, and I was delighted when he agreed to participate in this series.

As Patrick describes in greater detail below, like many who are fluent improvisers, he began playing by ear before learning to read music. While it may not be a universal theme, this is a pattern among many who are comfortable and enjoy improvising. The marvelous Dutch organist-improviser Sietze de Vries discusses this in his online course in improvisation, which may be found on his YouTube channel. He encourages all musicians to improvise, strongly endorses its development in children, and likens learning how to improvise as adults to learning a second language. Like all analogies, I am sure it is only true to a certain extent, but it is a compelling idea: if introduced in childhood, it is much easier than “taking the plunge” in adulthood. (Nonetheless, I, too, strongly wish to encourage everyone and anyone to improvise!)

Discussion

When, how, and why did you start playing by ear and inventing your own music? Did it coincide with your early music training?

I grew up in a small town in southern Mississippi, where we attended what was a large church for our town, with a forty-one-rank Möller organ. The organist there, Betty Polk, had a degree in organ and had complete facility at the instrument; she became my organ teacher throughout high school. I remember being about four years old when she used full organ for the final verse of one of the hymns we were singing. It was one of the most thrilling things I’d ever experienced. I remember going home and trying to pick out the melody on our piano (as well as a four-year-old could). My older brother was already taking lessons, so we were fortunate to have a piano in our home.

I continued doing this for a few weeks until my parents decided to contact my brother’s piano teacher. She said she usually didn’t take students as young as I was, but my mother explained to her that I was playing things by ear at home, and they just weren’t sure how best to nurture that. She asked my parents to bring me to one of my brother’s lessons. I played a hymn for her, probably “What a friend we have in Jesus,” including a very simplified left-hand accompaniment. Ms. Jacobs, the teacher, said that she would take me!

A few months later, I was playing one of my short pieces for the week when Ms. Jacobs realized that while I was playing the piece accurately, it was in the wrong key. We realized that my brother had been playing my pieces for me, after which I memorized them and played them back by ear. So, we had to take a couple of steps back, but I did finally learn to read music. Over my early years, my parents and my teachers were always encouraging my playing by ear. My teachers at each lesson would ask what I had come up with the week prior.

In my home church, all the service music was based on hymns: preludes, postludes, and offertories. So that’s how I modeled the different pieces that I would make up. A little introduction of some sort, a full statement of the melody either on a solo stop or with chords like a hymn, sometimes an interlude, often a key change, and some sort of ending—sometimes a simplified coda, and probably most times, full-blown Hollywood!

How did you employ improvisation in public over the course of your childhood?

My home church was always very open to having people of all ages participate in various ways of making music. In addition to its usual Sunday morning services, there was always a Sunday evening service. In months with five Sundays, we would have an old fashioned “Fifth Sunday Sing.” Surely it was a chance for clergy and musicians to take a break from their weekly task of having to create yet another service, and often it would just simply turn into a talent show.

I was probably five years old the first time I ever played anything; I’m sure it was very basic, but it allowed me to play in public and began to foster what would become a life-calling of being involved with church music. Over the years I would play more and more, beginning to accompany morning and evening services as I got older and more capable. I would learn pieces to play, but most often the preludes or postludes would be things that I would create myself.

Even on Sundays when I wasn’t scheduled to play, our church organist would stop me and ask if I wanted to play the prelude that day. “I don’t have anything prepared,” I would say, and every single time Ms. Betty would look at me and with a glimmer in her eye, say simply, “just make it up!” It wasn’t until I got to college that I realized this was really improvising.

As a child, to the extent that you improvised, did you understand the music theory behind what you were doing, or did that understanding catch up later?

I studied music theory with my teachers, but I really don’t think I took any of this into account while I was playing. I just played what sounded good to my ears. And if it didn’t sound good, I’d make up something else that did.

Was there a watershed moment that inspired you to develop your skills seriously?

Yes! I’ll never forget it! I had become pretty good at this “making up” stuff throughout college. I could create a hymn prelude in almost any style and key and was able to mold it to fit whatever part of the service it needed to be close to.

When I got to graduate school at the University of Texas at Austin, all students were required to study improvisation with Gerre Hancock. I was so excited, but Gerre wasn’t teaching it until the spring semester, and this was the first semester of school. We had the famous French organist Pierre Pincemaille coming to play a recital and work with us in an improvisation masterclass. Gerre asked during the studio class earlier in the week who would like to improvise; immediately every student looked at the floor so as not to make eye contact. He called out a few students and then of course called my name.

I went up afterward and said, “Dr. Hancock, I’ve never studied improvisation before.” And in a way only Gerre Hancock could, he patted my shoulder, smiled, and said, “Oh, Patrico, it’s going to be wonderful!” It turned out he would be away that weekend playing his own recital, as would Judith Hancock, so I really was all on my own.

Then came the day of the masterclass and my turn to play. We had a student fluent in French who was translating for M. Pincemaille. He asked me what form I was planning to improvise in. My look of panic was clearly enough to give away that I had no idea what he was talking about. The translator turned back to him and said, “Free form.” I had prepared a short hymn prelude on SLANE: a brief introduction, the first verse on a solo stop, a modulation, the second verse with chords like a hymn, and finally a little coda after which I called it a day. I finished and M. Pincemaille started screaming with a very thick French accent, “No! No! No! You must always start and end in the same key!”

The horrific embarrassment was only allowed to last for a second as he made me start again. I began the same way, and by the time I got to the end of the first phrase of the hymn melody, he told me to change keys and repeat the first melody line again, and then change keys again, repeat the melody in some other way, over and over and over again. I felt like I had changed keys a million times at this point, and finally he told me to start finding my way back to the home key.

Of course, you probably wouldn’t want to actually modulate that often, but he was trying to break the mold that I had created for myself. It was at that moment that I realized that improvising was so much more than just playing a melody straight through—that embellishment, repetition, form, rhythm, and harmony played such important roles in improvising.

Who were your principal teachers and influences in improvisation? How did you learn from them?

I was very lucky to have been a student of Gerre Hancock while at the University of Texas at Austin. All students would work through Gerre’s textbook, Improvising: How to Master the Art. Through the book, Gerre taught strict form and counterpoint. In addition to carefully working through each chapter of his volume, there are two specific things I remember from lessons that I still think about today.

First, he would ask each student prior to playing what their plan was: what form or keys might be used, and specifically how long it would be. In class, these were just exercises, not long improvisations. So a student could say twenty measures or so. Gerre would then count each measure, counting to ten and then backward from ten.

Even in a short exercise, a student was expected to introduce whatever material was to be used, and then by the tenth measure begin finding a way to the end. It made us think about each measure and what we were doing, forcing us to stay in a structured time signature, not just wandering aimlessly around the keyboard without any organization. We had to build a scaffold for our musical creations, not just haphazardly playing things at random.

Second, Gerre was famous for saying, “There are no wrong notes,” and he meant that! Many times, while working through free improvisations, he would give us scenarios. “Walking through Paris gathering items for a picnic by the Eiffel Tower while car horns honk in the background. Riding an elevator up, it stops, and then it goes back down, maybe it goes quicker on the way down causing panic. Walking through a public space and seeing people you like and then people you don’t like, and one is walking a dog.” They were extremely random scenarios, but then he would allow us to create improvisations that created the scene for those scenarios. It allowed us to be as free as we could ever possibly imagine.

I perhaps learned most by just listening to Gerre play, both in person and through recordings. His harmonic progressions, clever ways of treating the theme, rhythmic excitement, and flawless registrations made me want to run out and improvise immediately.

I remember in graduate school having a small keyboard in my apartment and sitting on the floor listening to his recordings and playing chords repeatedly until I figured out exactly what he was doing. It’s not just playing one “crunchy chord,” it’s more about how it’s approached and what happens after that. Think of the famous chord in David Willcocks’s setting of the last verse of “O Come, All Ye Faithful.” It’s only effective because of the three chords leading up to it. The same is true when trying to figure out different chords in improvising; what happens before and after a great chord is often more important than the chord itself. Gerre’s brilliance always showed forth. But I think the first half of his recording Christmas Improvisations, recorded on the Taylor & Boody in the gallery of Saint Thomas Church Fifth Avenue, presents his most incredible improvisations, offering the most unique and meticulous technique and style.

When did you first improvise in a concert setting?

I’m not sure I entirely remember, but what comes to mind was an improvisation on a submitted theme at the end of my master’s degree recital. It was not a requirement, but many of Gerre’s students would try their hand at this in degree recitals. Gerre would bring out a theme in a sealed envelope like so many did for him at the end of his recitals. The student would have to open the envelope with great suspense and then play through the tune.

I remember mine being the hymn tune HANOVER. Like most on-the-spot improvisations, I don’t remember much about it, but Gerre seemed pleased. I remember him mentioning that I had about three different endings and I could have perhaps wrapped it up sooner; I guess I was having too much fun!

You won first prize in the NCOI; to what extent has that influenced your career and your identity as an improviser? Have you entered other improvisation competitions?

The AGO’s NCOI competition is the only improvisation competition that I’ve been a part of. Preparing for it was quite daunting, but it pushed me to learn so many different styles and quite frankly return to the basics of being able to articulate what you’re planning to do in almost every measure.

I do feel like it was a turning point in my life as a musician, but especially an improviser. I always felt like I was never truly improvising, but just “making things up,” as I would always say. I felt like the word “improvise” was reserved for someone who knew everything they were doing at all times, through form and theory specifically, and I never felt like I had grasped that well enough. I’m not sure I still do today, to be completely honest, but preparing for and winning the competition allowed me to realize that I have put in a decent amount of study for all of this and could articulate what I was doing: specifically in regard to musical form, registration, theory, and so on.

Do you consider yourself to have your own distinct musical language? Is there anything distinctly “American” about your improvising?

I can’t say that I necessarily think of myself as having my own distinct musical language. I do love jazz, and there’s nothing more American than jazz, so hopefully there are some elements that can be heard in some of the harmony that I use. I’d like to think that my love for church music shines through more than anything else: I feel like my improvisations are more likely to sound like the hymn and psalm preludes of Howells, Brahms, Reger, Sowerby, Hancock, Willan, and Bach than the scherzos or huge toccatas of Vierne, Duruflé, and Tournemire. I love those works and composers, and I dabble in improvising in those styles sometimes when I sit down to play. I feel like the former is what’s most likely to come out of my fingers and feet.

Tell us more about imitating specific composers or periods: is it a different process altogether, or a different side of the same coin?

It’s always fun to imitate a composer or create something that sounds like it was composed during a specific period. A free improvisation or even a hymn prelude comes fairly easily to me, but it takes much more concentration to create something that specifically sounds like someone else. The Pachelbel partitas are always enjoyable to imitate and are actually a really solid way to practice improvising. It’s always fun to imitate the twentieth-century French improvisers like Tournemire or Langlais; just push tutti and come crashing down on dense French chords. I also love imitating French Classic composers like Nicolas de Grigny and François Couperin. It’s so satisfying to create a Tierce en taille, a Duo, a Récit de Cromorne, or Basse de Trompette. The counterpoint with these is often tricky and requires a good bit of practice, but it’s always worth it.

Do you compose much? How does improvisation differ from composing to you? Do you prefer one or the other?

I can’t say I compose very much. I wrote a book of hymn reharmonizations and descants published by Selah Publishing Company, and that’s about it. Because I don’t compose very often, it takes quite a bit of time to sit and write what’s going on in my head. I’d like to do more of it in the future. To me, improvising and composing are pretty much the same, because before I could compose anything, I’d have to play it first and figure it out. The problem comes when I can’t remember what I improvised the first time in order to write it down. I clearly prefer improvising to composing!

Conclusion

Patrick Scott’s humility came through when he wrote, “I felt like the word ‘improvise’ was reserved for someone who knew everything they were doing at all times, through form and theory specifically, and I never felt like I had grasped that well enough. I’m not sure I still do today, to be completely honest. . . .” While I (and anyone who hears him, surely) would say that Patrick is far more than worthy of being considered an extremely fine improviser, he does remind us of the adage, “The more one learns, the more one realizes what one doesn’t know.” I have learned a great deal from distinguished colleagues who have participated in this series thus far and look forward to learning even more as the series continues. Hearing their experiences, how they gained their skills, is at once informative and inspiring.

There are as many ways to improvise as there are to make music in general, yet most would agree that learning key skills in harmony, counterpoint, and form is essential to truly begin to unlock one’s potential. Along those lines, I recently shared on Facebook and Instagram a succession of posts on the above. I was pleasantly surprised that the first of them, especially, was shared very well beyond my own group of friends and followers. To follow what Patrick has said, and what he learned from the great Gerre Hancock, I conclude this article by incorporating some of my suggestions here, not necessarily in a particular order, except that the first six are under the banner of keyboard harmony and counterpoint, before moving on to form:

1. Be able to comfortably harmonize (using principles of sound voice leading) major and minor scales in all keys.

2. Practice simple circle of fifths sequences to be able to modulate quickly from a given key to any other key.

3. Learn to transpose any hymn into any and every other key, at sight.

4. Practice transposing to the Dorian, Phrygian, Lydian, and Mixolydian modes, beginning on all pitches.

5. Learn to play figured bass.

6. Learn to read open score of four or more parts, especially works by great polyphonists.

7. Play as many great organ works as possible to build technique and to deepen one’s musical vocabulary. Using familiar tunes or themes, imitate as many of these works as possible when practicing improvisation.

8. Practice constructing phrases comprising only four bars. Begin with simple, stepwise melodies; count aloud. Repeat this exercise frequently. Then improvise a phrase ending in the dominant (a half cadence) followed by one ending in the tonic (specifically, an authentic cadence). Start with melody only, and then add simple harmony. Two phrases make a period; depending on how similar the phrases are, the period will either be parallel or contrasting.

9. After gaining some degree of comfort with the above, improvise a new phrase based on the above, only in a closely related key (relative or dominant). End that new phrase with a half cadence, then add yet another phrase ending with an authentic cadence in that related key. Keep counting aloud as you play!

10. Try to memorize these phrases as best you can. Do not be reluctant to make notes for yourself. Repeat the first period, perhaps with some elaboration, like passing tones or simple ornaments.

11. If desired, add a four-measure introduction, interludes, and a coda (all comprising four measures). Keep counting. These may be very simple, just basic accompaniment figures. Keep counting!

12. Putting together numbers 8–11 above results in one of the simplest musical forms, a ternary or 
song form.

All the above was drilled into me by McNeil Robinson in regular lessons over an extended period (along with much else) and must be practiced as much as possible. Gerre Hancock was also a force in solidifying this in my mind, via that one extremely long lesson, a masterclass or two, and his textbook.

I am grateful to Patrick Scott for sharing so much wisdom with us in his interview. I look forward to what we will learn in future interviews.
