In the Wind. . . .

Mazel tov to muscle tone

We have a close friend in Maine who has always taken pride in his self-sufficiency. He built his own house, and in the twenty-five years he and his wife have lived there, he has done all the maintenance and improvements himself. As it is a rural house, there is extra work involved, like plowing a half-mile driveway, clearing brush and trees, and mowing a large lawn. They are just across the river from us, so like us, they have waterfront chores like taking docks and moorings in and out of the water. He is a tough and stubborn guy in his early seventies, and last winter he had a stroke.

I visited him in the rehab center where he spent several very difficult months learning to walk with new limitations, straightening out his speech, and adjusting to his new circumstance in general. His right arm and hand are now pretty much useless, and he was lamenting the loss of his “chain saw arm.” He could not imagine how he was going to be able to get the snowplow off his pickup truck, and the dormers on their roof needed shingle repairs. During that visit, it was simply not crossing his mind that he would likely not be able to do those things again.

Wendy and I had dinner at their house last week and were brought up to date on all those issues. He hired someone to repair the shingles, a friend took the plow off his truck, and he decided they would not put the docks in the water this year. In fact, he put his boat on the market. And though his wife is energetic and sprightly, they are considering selling their house and moving into a condominium, or even, dare they admit, an assisted living facility. With all those changes imposed on their lives, my pal is grateful that his speech is fine, and that with some difficulty he is able to walk, but he is astonished at the uselessness of his arm. “It hangs off my shoulder; I know it’s there. It hurts and itches sometimes, but I can’t make it move.”

Since that dinner, I have been reflecting on the miracle that is the human body, and the incredible things people can learn to do. All of us who are born with bodies that are normal and complete start with roughly the same equipment. Some people have little dexterity. The private nickname we have for one friend is “Oops.” But then there is the fellow who can throw a ball ninety feet and reliably hit a target about one-foot square, and there is the woman who can jump, twirl, and somersault on a beam that is ten centimeters (3.9 inches) wide.

The world of music is full of incredible examples. The human hand is the same apparatus that handles the “neck end” of a violin or guitar, the keys of an oboe or piano, or the strings of the harp. Have you ever shaken hands with a harpist? What may seem to be the simplest instrument is perhaps the most miraculous—the human voice. Stop and think what an incredible feat it is to simply match a pitch with your voice. How do we know exactly the tension of the countless muscles involved that will create that A-flat out of thin air? A choir starting a piece, a cappella, with each member confident of the pitch, volume, and timbre, is a dramatic example of human muscle control.

No musician can play two identical performances of the same piece. We study, train, and practice, trying to make accurate plans for where our fingers will go, where we want to emphasize something, where we want to bring something forward. We write fingerings into our scores, intending to use the same sequence of fingers on each sequence of notes in the hope that we can eliminate confusion. But something always comes up in performance that was not part of the plan. Maybe we got distracted. Or maybe something wonderful happened that never did before. It’s a thrill when you surprise yourself in performance with a special lilt, a delicious ritardando, or a thrilling and dramatic crescendo.

It’s a control issue.

Let’s take that muscle thing a little further. My friend’s stroke did not spoil the muscles in his right arm; it interrupted the electrical gear that operates them. The human nervous system is the amazing wiring harness that transmits our thoughts into muscular impulses. Our bodies include several hundred “visceral” muscles, those that perform involuntarily, running such equipment as our hearts, eyelids, and diaphragms. There are something like 320 symmetrical pairs of skeletal muscles, those that we exercise control over. When I googled that, I was surprised to learn that there seems to be disagreement over the actual number, apparently because some muscles can be considered as part of more complex structures and not counted separately.

I am something of a mechanical geek, which has allowed me to notice that controls of a backhoe, the most common piece of excavation equipment, are roughly equivalent to the nerves that operate our arms and hands. Each lever has opposite motions—left and right, up and down, flex and open—and the operator uses levers in combinations to make fluid compound motions. The boom extends, the bucket opens, the machine swivels all at once.

Watch a virtuoso musician playing a brilliant passage and think of all nerves firing to make those hundreds of muscles do exactly the right thing, at the right time, with the right amount of force. That’s some data stream.

Many musical instruments, including winds and strings, require the musician to participate in the production of tone, and the volume of every musical instrument is controlled by the muscular impulses of the musician. That is, every instrument but one. An organ pipe is perhaps the simplest of musical instruments, and certainly the least versatile. Any organ pipe can produce just one pitch at one volume level and one timbre. Period. Big deal. It is for that reason that many orchestral conductors consider the pipe organ to be expressionless. Conversely, I claim that a pipe organ, especially a large organ with electric stop action, is the most expressive of musical instruments. The catch is that the musician operates it remotely. The mechanics of the instrument serve as an artificial nervous system, allowing the musician to control the instrument. While I know I am opening a path for cruel jokes (he plays that organ like a Mack Truck!), there is a real analogy with that excavator operator causing a twenty-ton machine to move with fluid, human-like motion.

The musician’s workstation

I am thinking about organ consoles these days because I am working on one in my personal shop at our house in Maine. It is a three-manual job of modest size, about fifty years old, and I am refitting it with a new nervous system, that fantastic array of solid-state controls concealed in a series of small black boxes that have brought such sophisticated levels of control to the modern organist. Those black boxes were provided by a supplier who incorporated the original specifications of the organ, plus a slew of features that I wanted to add. There is a small LED screen at the heart of the control panel, the controls that control the controls.

The keyboards have been recovered and polished to provide a lovely visible sheen, but more importantly, a smooth surface to meet the musician’s fingers. There are no sharp edges or snags that could divert attention, or worse, cause injury. (I once covered a keyboard with blood from a deep slit in my finger caused by the jagged edge of a broken ivory, admittedly buried in my score enough that I did not look down until the piece was over.) The best keyboards are works of art whose beauty helps to inspire the musician.

All the stopknobs and pistons need to feel alike. A squeaky knob or a piston that clicks will distract the player and interrupt the flow. While it is impossible for everything to be perfect, the goal of the organbuilder is to make the machine disappear, or at least to minimize the machine’s ability to intrude on the sacred space between the musician’s heart and the sound of the pipes. I am requiring the musicians to take care of the arms, hands, and fingers part of the system.

Besides the switches and buttons that actually control the functions of the organ, the surrounding cabinet needs to be an inspiring workstation. The wood should be beautiful, the finishes smooth, the geometry perfect. All of these factors add to the console’s status as an extension of the musician’s body.

Cleanliness is . . .

There is a terrific hardware store in Damariscotta, Maine, the town that adjoins our village of Newcastle, and I go there at least every few days. It has a large parking lot with head-in spaces in front of the store, and a row of spaces you can enter from behind, leaving your car facing across an open lane at the store. There is typically a row of tradesman’s pickup trucks and vans lined up there, and I always notice which trucks are kept neat inside, and which have their dashboards piled high with soda cans, coffee cups, receipts, sandwich wrappers, tools, and hardware samples. I have used those observations to inform who I hire to help with our house. If a painter’s truck is covered with slobbers of paint and filled with empty coffee cups, I don’t want him in my house.

Traveling around maintaining organs provides the same experience. Some organ consoles are always clean and free of clutter, and some are nasty depositories that could have come straight from the dashboard of a plumber’s pickup truck with the same coffee cups, candy and food wrappers, nail clippers (ick), and hairbrushes. One organist I worked for had long thick gray hair and the console looked like the couch in a house with ten cats. Her hair tangled up in the pedal contacts causing dead notes. We called it the “Hairball Church.”

Often, those dirty consoles are out in the open in the front of the church for everyone to see. It’s hard to imagine why a musician would choose to present such a front for the worshippers. And it’s hard to imagine how a sloven could produce beautiful music from such a sty. I understand the value of having pencils, note pads, “stick-ems,” and even paper clips handy (though paper clips falling into keyboards have necessitated many an emergency call!), but you should take your trash with you when you leave. The one that really gets me is the half-sucked lozenge sitting on the open wrapper. You didn’t finish that lozenge? Really? A few paragraphs ago, I referred to an organ console as an extension of the musician’s body, perhaps a little idealistic if the console is a mess.

§

A modern solid-state organ console is loaded with creative functions that allow the musician ever higher levels of control over the instrument. Multiple levels of memory and piston sequencers are two concepts that were really not possible before the introduction of solid-state equipment. Like the old codger who starts a conversation with a grandchild with the words, “When I was your
age . . . ,” I like to share that it was a big deal when my high school purchased four four-function calculators (add, subtract, multiply, divide). But it was only a few years later, when as an apprentice, I participated in installing one of the earliest solid-state combination machines. A lot of smoke came out.

As incredible as these machines can seem, organ consoles built a century ago featured sophisticated functions requested by the pioneers of symphonic organ playing. Lynnwood Farnam was organist at Emmanuel Church in Boston when Casavant’s Opus 700 was installed there in 1917. That console featured such controls as:

• Piston “throwing off” all manual 16′ stops, also Quint 51⁄3′ and Tierce 31⁄5′

• Piston “throwing off” all subcouplers

• Swell octave couplers to cut off Swell 2′ stops

• Other manual 16′ and 2′ stops not to be cut off by octave or sub couplers.

What was he thinking? That was barely the time when you could expect a new organ to include an electric blower. (After sitting in storage for more than ten years, that organ has recently been renovated by Rieger and installed in a concert hall on an island in China.)

Mr. Farnam was involved in the design of another console that I have written about before, that of the new Skinner Opus 707 built in 1928 for Grace Church, New York City. Farnam’s dear friend George Mitchell was organist there, and together they dreamed up a behemoth console that could seemingly do anything. The console controlled a double organ, Chancel and Gallery, with a total of 167 stops and 133 ranks. There was a separate crescendo for each organ. Above the Gallery Crescendo pedal there were two toe studs, marked “Regular” and “Orchestral.” The Chancel Crescendo pedal could be programmed from the console, using a wire-and-plug system located in a drawer under the bottom keyboard. A programmable crescendo in 1928! Besides the two crescendo pedals, there were five expression pedals, with a sliding control switch that allowed the organist to assign any expressive division to any pedal.

It is amazing to think of that level of electrical control in a contraption built in 1928. It was the product of some of the world’s most creative musical minds expanding the expressive possibilities of the most complex and least personal of all musical instruments. It is as if a puppeteer added 320 symmetrical pairs of strings to the marionette, mimicking the repertory of human skeletal muscles.

Because of that heritage of creativity, combined with the added dimensions made possible with solid-state controls, the supposed least expressive of musical instruments eclipses the expressive capabilities of the symphony orchestra. It can be softer than the softest, louder than the loudest, and with a few flicks of fingers, create dramatic crescendos between extremes.

When Wendy and I lived in Boston, we had series tickets for the Boston Symphony Orchestra, with seats near the curve just above the stage. During the first performance using the newly renovated organ, with Simon Preston playing the obligatory Organ Symphony by Saint-Saëns, we marveled at the facial expressions and communication between orchestra members as the super low notes came from the organ during the slow movement. No orchestral instrument can go as low as the organ, and it is partly because of the limitless supply of air that the organ can blow whistles that big.

Are you surprised when I suggest that the organ is the least personal of musical instruments? I don’t feel that way when I play, rather I feel at one with the instrument, excited by the range of things I can make it do, excited by the way its sound rings in a huge room, excited by the way my musical impulses can make a whole room ring. It feels very personal to me, but as an organbuilder, I cannot separate all that from the fact that the organ is a machine operated by remote control. Like a pantograph that magnifies the size of a drawing using proportional levers, so the machine that is the organ magnifies the vision of the musician. But please, take your trash with you.

What’s it going to cost?

When you’re shopping for a car, it’s reasonable to start by setting a budget. Whether you say $10,000, $30,000, or $75,000, you can expect to find a vehicle within a given price range. Of course, it’s up to you whether or not you stick to your budget, but we all have experience with the exercise, and there’s plenty of solid information available. Printed advertisements broadcast prices in huge type, and you can fill in forms online with details about a given car to receive a generated price.

When you set out to buy a piano, you can start with a simple search, and get a quick idea of price ranges. I just spent a minute or two surfing the internet to learn that a new Steinway “B” (that’s the seven-foot model) sells for over $80,000, and that you should expect to pay about 75% the price of a new instrument to purchase a reconditioned used piano. If you start with that in mind and do some serious shopping, you may well get lucky and find a beautiful instrument for less, but at least you have a realistic price range in mind before you start.

There is simply no such information or formulas available for the acquisition of a pipe organ, whether you are considering a new or vintage instrument. In a usual week at the Organ Clearing House, I receive at least two, and as many as ten first-time inquiries from people considering the purchase of an organ. These messages often include a stated budget, usually $100,000, sometimes $200,000, and they typically specify that it should be a three-manual organ. Each time, I wonder how that number was generated. Was it the largest amount they could imagine spending? Did they really think that an organ could be purchased for such an amount?

It’s as if you were shopping for that car, but you promised yourself that this time, you’re going to get your dream car. You test-drive a Mercedes, a Maserati, and a Bentley, and oh boy, that Bentley is just the thing. You offer the salesman $20,000. He rolls his eyes and charges you for the gas. It’s a $250,000 car.

§

There’s a popular myth out there that people think that organ companies can be compared by their “price per stop.” The most common source for public information about the price of an organ is the publicity surrounding the dedication of a monumental new organ. You read in the newspaper that Symphony Hall spent $6,500,000 on a new organ with 100 stops. Wow. That’s $65,000 per stop. We only need a ten-stop organ. We could never raise $650,000.

The problem with this math is that the big concert hall organ has special features that make it so expensive. The most obvious is the 32′ façade. How much do you think those pipes cost? If they’re polished tin, the most expensive common material, maybe the bottom octave of the 32′ Principal costs $200,000? $250,000? More? And if the organbuilder pays that to purchase the pipes, what does it cost to ship them? A rank of 32-footers is most of a semi-trailer load. What does it cost to build the structure and racks that hold them up? This week, the Organ Clearing House crew is helping a colleague company install the 32′ Open Wood Diapason for a new organ. It takes ten people to carry low CCCC, and once you have it in the church, you have to get it standing upright. Years ago, after finishing the installation of a full-length 32′ Wood Diapason in the high-altitude chamber of a huge cathedral, my colleague Amory said, “Twelve pipes, twelve men, six days.” It’s things like that that pump up the “price per stop.” In that six-million-dollar organ, the 32′ Principal costs $400,000, and the 13⁄5′ Tierce costs $700.

Here’s another way to look at the “price per stop” myth. Imagine a two-manual organ with twenty stops­—Swell, Great, and Pedal, 8′ Principal on the Great, three reeds, and the Pedal 16′ stops are a Bourdon and a half-length Bassoon. The biggest pipes in the organ are low CC of the Principal, and low CCC of the Bourdon, and the organ case is 18 feet tall. Add one stop, a 16′ Principal. Suddenly, the case is twice as large, the wind system has greater capacity, and the organ’s internal structure has to support an extra ton-and-a-half of pipe metal. The addition of that single stop increased the cost of the organ by $125,000, which is now divided over the “price per stop.”

Or take that 21-stop organ with the added 16′ Principal, but instead of housing it in an organ case, you install it in a chamber. In that comparison, the savings from not building a case likely exceeded the cost of the 16′ Principal.

Ballpark figures

On June 10, 1946, a construction manager named Joseph Boucher from Albany, New York, was sitting in seat 21, row 33 of the bleachers in Boston’s Fenway Park, 502 feet from home plate. Ted Williams hit a home run that bounced off Boucher’s head and wound up 12 rows further away. Boucher’s oft-repeated comment was, “How far away does a guy have to sit to be safe in this place.” That still stands as the longest home run hit at Fenway, and Boucher’s is a solitary red seat in a sea of blue. That’s a ballpark figure I can feel comfortable with. I have other stories saved up that I use sometimes as sassy answers when someone asks for a “ballpark figure” for the cost of moving an organ.

If you’re thinking about acquiring a vintage organ, you’ll learn that the purchase prices for most instruments are $40,000 or less. Organs are often offered “free to a good home,” especially when the present owner is planning a renovation or demolition project, and the organ has transformed from being a beloved asset to a huge obstacle. But the purchase price is just the beginning. 

If it’s an organ of average size, it would take a crew of four or five experts a week to dismantle it. Including the cost of building crates and packaging materials, dismantling might cost $20,000. If it’s an out-of-town job for the crew, add transportation, lodging, and meals, and it’ll cost more like $30,000. If it’s a big organ, in a high balcony, in a building with lots of stairs, and you can’t drive a truck close to the door, the cost increases accordingly. With the Organ Clearing House, we might joke that there’s a surcharge for spiral staircases, but you might imagine that such a condition would likely add to the cost of a project.

Once you’ve purchased and dismantled the organ, it’s likely to need renovation, releathering, and perhaps reconstruction to make it fit in the new location. Several years ago, we had a transaction in which a “free” organ was renovated and relocated for over $800,000. The most economical time to releather an organ is when it’s dismantled for relocation. Your organbuilder can place windchests on sawhorses in his shop and perform the complex work standing comfortably with good lighting, rather than slithering around on a filthy floor in the bottom of an organ.

The cost of renovating an organ is a factor of its size and complexity. For example, we might figure a basic price-per-note for releathering, but the keyboard primary of a Skinner pitman chest with its double primaries costs more than twice as much to releather as does a chest with single primary valves. A slider chest is relatively easy to recondition, unless the windchest table is cracked and split, and the renovation becomes costly reconstruction.

It was my privilege to serve as clerk of the works for the Centennial Renovation of the 100-stop Austin organ in Merrill Auditorium of City Hall in Portland, Maine. (It’s known as the Kotzschmar Organ, dedicated to the memory of the prominent nineteenth-century Portland musician, Hermann Kotzschmar.) That project included the usual replacement of leathered pneumatic actions, but once the organ was dismantled and the windchests were disassembled, many significant cracks were discovered that had affected the speed of the actions for generations. Another aspect of the condition of that organ that affected the cost of the renovation was the fact that many of the solder seams in larger zinc bass pipes were broken. The effect was that low-range pipe speech was generally poor throughout the organ, and it was costly to “re-solder” all of those joints, a process that’s not needed in many organ renovations.

It’s generally true that if an organ that’s relatively new and in good condition is offered for sale, the asking price will be higher knowing that the renovation cost would be low or minimal. But sometimes newer organs are offered for low prices because they urgently need to be moved.

Let’s consider some of the choices and variables that affect the price of an organ:

Reeds

With the exception of lavish and huge bass stops, like that 32-footer I mentioned above, reeds are the most expensive stops in the organ. They’re the most expensive to build, to voice, to maintain­—and when they get old, to recondition. When you’re relocating an organ, the quality of work engaged for reconditioning reeds will affect the cost of the project and is important to ensuring the success of the instrument. You would choose between simply cleaning the pipes and making them speak again by tuning and fiddling with them or sending them to a specialist who would charge a hefty fee to repair any damage, replace and voice the tongues, mill new wedges, and deliver reeds that sound and stay in tune like new.

Keyboards

An organbuilder can purchase new keyboards from a supplier for around $1,000 each to over $10,000. The differences are determined by the sophistication of balance, weighting, tracker-touch, bushings, and of course, the choice of playing surfaces. Plastic covered keys are cheaper than tropical woods, bone, or ivory, which is now officially no-touch according to the United States Department of the Interior (remember President Obama and Cecil the Lion). Some organbuilders make their own keyboards and don’t offer choices, but especially in renovations, such choices can make a difference.

Climate

If an older organ has been exposed to extremes of dryness, moisture, or sunlight, it’s likely that the cost of renovation will be higher because of the need to contain mold, splits, and weakened glue joints.

Casework

A fancy decorated organ case with moldings, carvings, and gold leaf is an expensive item by itself. As with keyboards, some builders have a “house style” that is built into the price of every organ they build. If you don’t want moldings, towers, and pipe shades, you can ask someone else to build the organ. Especially with electro-pneumatic organs, chamber installations are often an option, and are considerably less expensive than building ornate casework. However, I believe that it’s desirable for a pipe organ to have a significant architectural presence in its room, whether it’s a free-standing case or a well-proportioned façade across the arched opening of a chamber.

Console

Drawknob consoles are typically more expensive than those with stoptabs
or tilting tablets. Sumptuous and dramatic curved jambs speak to our imagination through the heritage of the great Cavaille-Coll organs, especially the unique and iconic console at Saint-Sulpice in Paris. Those dramatic monumental consoles were the successors of the seventeenth- and eighteenth-century stop panels, as found on the Müller organ at Haarlem or the Schnitger at Zwolle, both in the Netherlands. The default settings of most woodworking machinery are “straight” and “square,” and by extension, curves require more work and greater expense.

Many modern consoles and most renovation projects include the installation of solid-state controls and switching. There is a range of different prices in the choice of which supplier to use, and the cost of individual components, such as electric drawknob motors, vary widely.

What’s the point?

Some of the items I’ve listed represent significant differences in the cost of an organ, while some are little more than nit-picking. Saving $30 a pop by using cheap drawknob motors isn’t going to affect the price of the organ all that much. And what’s your philosophy? Is cheap the most important factor? When you’re commissioning, building, purchasing, or relocating a pipe organ, you’re creating monumental liturgical art. I know as well as anyone that every church or institution that’s considering the acquisition of an organ has some practical and real limit to the extent of the budget. I’ve never seen any of the paperwork between Michelangelo and Pope Julius II, who commissioned the painting of the Sistine Chapel, but it’s hard to imagine that the Pope complained that the scheme included too many saints and should be diminished.  

You may reply that putting a 20-stop organ in a local church is hardly on the scale of the Sistine Chapel, but I like to make the point that the heart of planning a pipe organ should be its artistic content, not its price. If you as a local organist dream of playing on a big three-manual organ, and you imagine it sounding like the real thing, and functioning reliably, you can no more press a job for $100,000 or $200,000 than you can drive away in the Bentley for $20,000.

Let’s think about that three-manual organ. Money is tight, so we think we can manage 25 stops, which means that while you’ve gained some flexibility with the third keyboard, that extra division might only have five or six stops, not enough to develop a chorus and provide a variety of 8′ tone or a choice of reeds. Sit down with your organbuilder and work out a stoplist for 25 stops on two manuals, and you’ll probably find that to be a larger organ because without the third manual you don’t need to duplicate basic stops at fundamental pitches. Manual divisions with eight or ten stops are more fully developed than those of five or eight, and let’s face it, there’s very little music that simply cannot be played on a two-manual organ. Further, when we’re thinking about relatively modest organs in which an extra keyboard means an extra windchest, reservoir, and keyboard action, by choosing two manuals instead of three, you may be reducing the cost of the mechanics and structure of the organ enough to cover the cost of a few extra stops.

Let the building do the talking.

Because a pipe organ is a monumental presence in a building and its tonal structure should be planned to maximize the building’s acoustics, the consideration of the building is central to the planning of the instrument. It’s easy to overpower a room with an organ that’s too large. Likewise, it’s easy to set the stage for disappointment by planning a meager, minimal instrument.

Maybe you have in your mind and heart the concept of your ideal organ. Maybe that’s an organ you played while a student or a visiting recitalist. Or maybe it’s one you’ve seen in photos and heard on recordings. But unless you have the rare gift of being able to picture a hypothetical organ in a given room, there’s a good chance that you’re barking up the wrong tree.

While I state that the building defines what the organ should be, five different organbuilders will propose at least five different organs. Think about what the room calls for, think about the needs of the congregation and the music it loves, and conceive what the organ should be. Then we’ll figure out how to pay for it.

It works for me.

After I graduated from Oberlin, we lived in a rented four-bedroom farmhouse with a huge yard in the rolling countryside a few miles outside the town. Foreshadowing fracking, there was a natural gas well on the property that supplied the house. It was a great place to live, but there were some drawbacks. The gas flowed freely from the well in warm weather, but was sluggish in cold. The furnace was mounted on tall legs because the basement flooded. All the plumbing in the house was in a wing that included kitchen, bathroom, and laundry machines, but the basement didn’t extend under the wing, so the pipes froze in cold weather. 

After a couple winters there, we had wrapped the pipes with electrified heating tape, mastered how to set the furnace to run just enough when the gas well was weak, and learned to anticipate when the basement would flood so we could run a pump and head off the mess. 

Outside, there was a beautiful redbud tree, several huge willows, acres of grass to mow, and the residual effects of generations of enthusiastic gardening. One summer, the peonies on either side of the shed door grew at radically different rates. One was huge and lush while the other was spindly. I was curious until I investigated and found an opossum carcass under the healthy one. Not that you would read The Diapason for gardening tips, but I can tell you that a dead ’possum will work wonders for your peonies!

I wanted to care for that landscape, so I bought an old walk-behind Gravely tractor with attachments. I could swap mower for roto-tiller for snow-blower, and there was a sulky—a two-wheeled trailer with a seat that allowed me to ride behind when mowing. I remember snatching cherry tomatoes off the vines, hot from the sunlight, as I motored past the garden.

I was the only one who could get the Gravely to start, at least I think so, given that I was only one who used it. It had a manual choke that had to be set just so. Then, as I pressed the starter button with my right toe, I’d move the throttle from fully closed to about a quarter open, and the engine would catch. I’d run it at that slow speed for about ten seconds, and it would be ready to work. If I did anything different, it would stall.

The bigger the toys . . .

I learned a lot about machines from Tony Palkovic who lived across the street. He had an excavating business and owned a fleet of huge machines. One weekend I helped him remove the drive wheels from his 110,000-pound Caterpillar D-9 bulldozer to replace the bearings. It involved a couple house jacks and 6-inch open-end wrenches that were eight feet long and weighed a hundred pounds. He used his backhoe to lift the wheels off the axles, not a job for “triple A.” I admired his affinity for his machines, and it was fun to watch him operate them. The way he combined multiple hydraulic movements with his fingertips on the levers created almost human-like motions, and he liked to show off by picking up things like soda cans with the bucket of a 40-ton machine.

The soul of the machine

In The Soul of the New Machine (Little, Brown, and Company, 1981), author Tracy Kidder follows the development of a new generation of computer technology, and grapples with the philosophical questions surrounding the creation and advances of “high-tech.” We’re beholden to it (witness the lines at Apple stores recently as the new iPhone was released), but we might not be sure if the quality of our lives is actually improved. Yesterday, a friend tweeted, “There’s a guy in this coffee shop sitting at a table, not on his phone, not on a laptop, just drinking coffee, like a psychopath.” Have you ever sat on a rock, talking with a friend, dangling your toes in the water until the rising tide brings the water up to your knees?

There’s a mystical place where soul and machine combine to become a pipe organ. The uninitiated might look inside an organ and see only mechanical mysteries. Many organs are damaged or compromised by uninformed storage of folding chairs and Christmas decorations within. But the organ is a complex machine whose inanimate character must disappear so as not to interfere with the making of music.

Musicians have intimate relationships with their instruments. In Violin Dreams (Houghton Mifflin Company, 2006, page 5), Arnold Steinhardt, first violinist of the Guarneri Quartet, writes, “When I hold the violin, my left arm stretches lovingly around its neck, my right hand draws the bow across the strings like a caress, and the violin itself is tucked under my chin, in a place halfway between my brain and my beating heart.” 

No organist can claim such an affinity, not even with the tiniest, most sensitive continuo organ. Steinhardt refers to instruments that you “play at arm’s length.” More usually, the organist sits at a set of keyboards separated from the instrument by at least several feet, and sometimes by dozens or even hundreds of feet. And in the case of electric or electro-pneumatic keyboard actions, he is removed from any direct physical or mechanical connection with the instrument he’s playing. He might as well phone it in.

A pipe organ of average size is a complex machine. A thirty-stop organ has about 1,800 pipes. If it’s a two-manual tracker organ, there are 154 valves controlled by the keys, a system of levers (multiplied by thirty) to control the stops, a precisely balanced action chassis with mechanical couplers, and a wind system with self-regulating valves, along with any accessories that may be included. If it’s a two-manual electro-pneumatic organ, there are 1,800 note valves, 122 manual primary valves (twice that many if it’s a Skinner organ), and hundreds of additional valves for stop actions, bass notes, and accessories.

But the conundrum is that we expect all that machinery to disappear as we play. We work to eliminate every click, squeak, and hiss. We expect massive banks of expression shutters to open and close instantly and silently. We’re asking a ten-ton machine in a monumental space to emulate Arnold Steinhardt’s loving caress. 

It’s a “one-off.”

Most of the machines we use are mass-produced. The car you buy might be the 755,003rd unit built to identical specifications on an automated assembly line. If there’s a defect, each unit has the same defect. But while individual components in an organ, such as windchest actions, might be standardized at least to the instruments of a single builder, each pipe organ is essentially a prototype—one of a kind. The peculiarities of an organ chamber or organ case determine the routes of mechanical actions, windlines, and tuning access. The layout of the building determines where the blower will be located, as well as the relationship between musician and machine.

The design of the instrument includes routing wind lines from blower to reservoirs, and from reservoirs to windchests. Each windchest has a support system: ladders, passage boards, and handrails as necessary to allow the tuner access to all the pipes. An enclosed division has a frame in which the shutters are mounted and a mechanism to open and close the shutters, either by direct mechanical linkage or a pneumatic or electric machine. Some expressive divisions are enclosed in separate rooms of the building with the expression frame and shutters being the only necessary construction, but others are freestanding within the organ, so the organbuilder provides walls, ceiling, access doors, ladders, and passage boards as required. The walls and ceiling are ideally made of a heavy, sound-deadening material so the shutter openings are the only path for egress of sound.

What’s in a tone?

Galileo said, “Mathematics is the language in which God wrote the universe.” While it may not be immediately apparent, mathematics is the heart of the magic of organ pipes. Through centuries of experimentation, organbuilders have established “norms” that define the differences between, say, flute tone and principal tone. The physical characteristics of organ pipes that determine their tone are defined using ratios. The “scale” of the pipe is the ratio of the length to the diameter. The “cut-up” that defines the height of a pipe’s mouth is the ratio of mouth height to the mouth width. The “mouth width” is the ratio of mouth width to the circumference. The type and thickness of the metal is important to the tone, so the organbuilder has to calculate, or guess, what material to use in order to achieve just the tone he’s looking for.

Finally, the shape of the pipe’s resonator is a factor. A tapered pipe sounds different from a cylindrical pipe, and the taper is described as a ratio of bottom diameter to top diameter. A square wooden pipe sounds different from a round metal pipe. A stopped wooden pipe sounds different from a capped metal pipe, even if the scales are identical. When comparing the scale of a wood pipe to that of a metal pipe, the easiest criterion is the area of the pipe’s cross section—depth times width of the wood pipe is compared to πr² of the metal pipe. If the results of those two formulas are equal, the scale is the same.

The reason all these factors affect the tone of the pipes is that each different design, each different shape, each different material chosen emphasizes a different set of harmonics. The organbuilder, especially the voicer or the tuner, develops a sixth sense for identifying types of pipes by their sounds. He instantly hears the difference between a wood Bourdon and a metal Gedeckt, or between the very narrow-scale Viole d’Orchestre and the slightly broader Salicional. He can tell the difference between high and low cutup just by listening. Conversely, his intuition tells him which selections of stops, which types of material, what level of wind pressure will produce the best sounding organ for the building.

The keen-eared organist can intuit all this information. Why does a Rohrflöte 8′ sound good with a Koppelflöte 4′? You may not know the physical facts that produce the complementary harmonics, but if you’re listening well, you sure can hear them. Early in my organ studies, a teacher told me not to use a Flute 4′ with a Principal 8′. Fair enough. That’s true in many cases. But it might be magical on a particular organ. Ask yourself if a combination sounds good—if it sounds good, it probably is good.

The whole is greater than the sum of the parts.

If the organ is part machine and part mathematics, and the musician is physically separated from the creation of tone, how can it be musical or artistic? How can an organist achieve the sensitivity of a violinist or a clarinetist who have direct physical control over the creation of tone? If you don’t have a good embouchure, you don’t make pretty sounds.

While I’ve talked about mechanisms and the mystical properties of the sound of the pipes driven by their math, we’re still missing something. Without wind, we have nothing but a big pile of wood, metal, and leather. Wind is a lively, living commodity. It has character and life. It’s endlessly variable. Outdoors in the open climate, wind is capricious. Any sailor knows that. You can be roaring along with white water boiling from under your transom, sails and sheets taut, and suddenly you fall flat as the wind dies. Or it shifts direction a few points and instead of drawing you along, it stops you dead.

Inside our organs, we harness the wind. We use electric blowers that provide a strong steady supply of wind, we build windlines and ducts that carry the wind from one place to another without loss through leakage. We design regulators with valves that regulate the wind (we also call them reservoirs because they store the regulated pressurized air), and respond to the demands of the music by allowing air to pass through as the valves open and the speaking pipes demand it, and our windchest actions operate those valves as commanded by the keyboards under the hands of the musician.

When you’re sitting on the bench, or inside the organ chamber, and the organ blower is off, the whole thing is static, inanimate. It’s like the violin or clarinet resting on padded velvet inside a locked case. I’ve always loved the moment when the blower is turned on when I’m inside an organ. You hear the first rotations of the motor, the first whispers of air stirring from the basement, and a creak or two as reservoirs fill and the springs pull taut. Hundreds of things are happening. When the blower is running at full speed and all the reservoirs have filled, the organ is alive and expectant—waiting to be told what to do. And at the first touch of the keyboard, the music begins.

Defining the indefinable

Once we’re playing, we enter the world of metaphysics. Intellectually, we understand how everything is functioning, but philosophically, we can hardly believe it’s true. Combinations of stops blend to create tone colors that otherwise wouldn’t exist. Peculiarities of acoustics create special effects heard in one location, but nowhere else. The motion of the air is apparent in the sound of the pipes, not, as a wag might quip, because faulty balance or low supply makes the wind wiggle, but because that air is alive as it moves through the organ’s appliances.

It’s that motion of wind that gives the organ soul. This is why the sounds of an electronic instrument can never truly equal those of the pipe organ. Sound that is digitally reproduced and funneled through loudspeakers can never have life. The necessary perfection of repetition of electronic tone defies the liveliness of the pipe organ. Just like the mouth-driven clarinet, it’s impossible that every wind-driven organ pipe will sound exactly the same, every time it’s played. It’s the millions of nearly imperceptible variations that give the thing life.

This starts to explain how the most mechanical and apparently impersonal of musical instruments can respond differently to the touch of different players. I’ve written several times about our experience of attending worship on Easter Sunday at St. Thomas’s Church in New York, when after hearing different organists playing dozens of voluntaries, hymns, responses, and accompaniments, the late John Scott slid onto the bench to play the postlude. The huge organ there is in questionable condition and soon to be replaced, but nonetheless, there was something about the energy passing through Scott’s fingers onto the keys that woke the gale that is the organ’s wind system and set the place throbbing. It was palpable. It was tangible. It was indescribable, and it was thrilling.

My friend Tony cared about his machines, not just because they were the tools with which he made his living, but because their inanimate whims responded to his understanding. We survived in that beguiling but drafty and imperfect house because as we loved it, we got to know it, and outsmarted most of its shortcomings. And I had lots of fun with that old Gravely, taking care of it, coaxing it to start, and enjoying the results of the mechanical effort.

Tony’s D-9 moved dirt—lots of dirt. But the sound of the organ moves me. And because I see it moving others, it moves me more. It’s all about the air.

Who you gonna call?

When I was an organ major at Oberlin in the mid-1970s, I had a part-time job working for Jan Leek, a first-generation Hollander who came to the United States to work for Walter Holtkamp and wound up as Oberlin’s organ and harpsichord technician. Traveling around the Ohio and Pennsylvania countryside with Jan making organ service calls, I learned to tune and learned the strengths and weaknesses of action systems of many different organbuilders. I moved back to Boston in 1984 with my wife and two young sons to join the workshop of Angerstein & Associates, where along with larger projects including the construction of new organs, I made hundreds of service calls. That workshop closed in 1987 when Daniel Angerstein was appointed tonal director for M. P. Möller, and I entered a decade during which I cared for as many as 125 organs each year as the Bishop Organ Company.

I’ve always been an advocate for diligent organ maintenance, but ironically, I’ve noticed in my work with the Organ Clearing House that century-old instruments that have never been maintained are sometimes the most valuable. The pipes are straight and true, the original voicing is intact, and there’s not a trace of duct tape anywhere. You remove a dense layer of grime (mostly carried out of the organ on your clothes) to reveal a pristine instrument. You might take that as an argument not to maintain an organ, but the truth is that I’ve found most of those organs in remote humble churches, where in many cases they haven’t been played for decades.

The challenge for the conscientious organ technician is not to leave a mark. If your tuning techniques damage pipes, you’re not doing it right. You should not leave scrape marks on the resonators with your tuning tools, and you shouldn’t tear open the slots of reed pipes. Cone-tuned pipes should stay cylindrical with their solder seams unviolated. Wiring harnesses should be neat and orderly, with no loopy add-ons. Floors and walkboards should be vacuumed and blower rooms should be kept clean.

There are legitimate excuses for fast-and-dirty repairs during service calls, especially if you’re correcting a nasty problem just before an important musical event. But if you do that, you owe it to the client to make it nice when you return.¹ And, when you do make a fast-and-dirty repair, you should adjust your toolkit to accommodate the next one. Did you use a scrap from a Sunday bulletin to refit the stopper of a Gedeckt pipe? Put some leather in your toolbox when you get home.

Many of the churches where I’ve maintained organs are now closed. Many others have diminished their programs and aren’t “doing music” anymore. Some tell me that they can’t find an organist, which is often because they’re not offering a proper salary, and some have “gone clappy.” In this climate, I think it’s increasingly important for organ technicians to be ready to help churches care properly and economically for their pipe organs.

Some churches charge their organists with curatorial responsibilities, purposely placing the care of the organ in the musician’s job description. Others do not, and it’s often a struggle to get boards and committees to grasp the concept of responsible care of their organs. It’s also important to note that while most churches once had full-time sextons or custodians, that position is often eliminated as budgets are cut. Lots of church buildings, especially larger ones, have sophisticated engineering plants that include HVAC, elevators, alarm systems, and sump pumps. The old-time church sexton knew to keep an eye on all that, and to be sure they were serviced and evaluated regularly. Hiring an outside vendor to clean the building does not replace the custodian. I think it makes sense for such a church to engage a mechanical engineer as consultant to visit the building a few times each year checking on machinery, and have volunteers clean the building.

A pipe organ is a machine like none other, a combination of liturgical art and industrial product. A layman might look inside an organ chamber and see a machine, but the musician sits on the bench facing a musical instrument. If you think that the governing bodies of your church don’t fully appreciate the value of their organ, I offer a few thoughts you might use to raise awareness.

“Cleanliness is next to Godliness”

It’s an old saw, but besides your personal hygiene, there’s likely nowhere in your life where it rings truer than in your pipe organ. After fire, flood, and vandalism, dirt is the worst enemy of the pipe organ. An organ technician knows that a fleck of dust getting trapped on the armature of a chest magnet or the surface of a pallet is enough to cause a cipher. The leg of a spider will wreck the speech of a trumpet pipe, most likely one of the first five notes of the D-major scale, ready to spoil almost every wedding voluntary.

But where did that dirt come from? When building windchests, windlines, bellows, and wind regulators, the organbuilder tries hard to ensure that there’s no sawdust left inside. I have an air compressor and powerful vacuum cleaner permanently mounted by my workbench so I hardly have to take a step to clean the interior of a project I’m finishing.

Assuming that the organbuilder delivered a clean organ, the first obvious place for an organ to pick up dirt is in the blower room. Many organ blowers are located in remote basement rooms, and in many cases, there’s no one changing the light bulbs in basement corridors, and there’s no one in the building who knows what that thing is. We routinely find blower rooms chock full of detritus—remnants of Christmas pageants, church fairs, flea markets, and youth group car washes. Organ blowers can have electric motors of five horsepower or more, and I often see 90 or 100-year-old motors that throw impressive displays of sparks when they start up. If the ventilation is obstructed, a fire hazard is created. That sign from the 1972 church fair isn’t that important. Throw it away.

To illustrate the importance of cleanliness, I share our protocol for cleaning a blower room:

• Seal the blower intake with plastic and tape.

• Close the circuit breaker that provides power to the blower so it can’t be started accidentally.

• Vacuum, sweep, wash walls, ceiling, floor, blower housing, wind regulators, and ductwork.

• Leave the room undisturbed for 48 hours to allow dust to settle before opening and starting the blower.

Likewise, if a church fails to cover and protect their organ while the floor of the nave is sanded and refinished, they can expect serious trouble in the future.

Identification

As organist, you might be the only person in the church who can identify the areas occupied by the organ. Designate organ areas as “off limits,” with access limited to the organ technician. Nothing good will happen if the organ chamber is used for storage of old hymnals or folding chairs. Nothing good will happen if teenagers find their way inside to create a secret hidey-hole.² Nothing good will happen if the altar guild puts a vase full of water on the organ console, and, by the way, nothing good will happen if you put your coffee cup there.

The organ’s tuning will almost certainly be disrupted if someone goes into the chamber out of curiosity. Most things inside pipe organs that are not steps lack the “no step” marking, like the touchy areas on an aircraft wing have.

Insurance

Maybe that 1927 Skinner organ in your church (lucky you) cost $9,500 to build. In the early 1970s, a new two-manual Fisk organ cost less than $40,000. I’m frequently called as consultant when a church is making a claim for damage to their organ, working either for the church or the insurance company, and I’ve been in plenty of meetings where bad news about the difference between loss and coverage is announced. It’s both possible and wise to have the replacement value of an organ assessed every five or ten years, with that value named on the church’s insurance policy.

If the organ at your church sustains $250,000 of damage because of a roof leak, and the replacement value of the organ is not specifically listed on the church’s insurance policy, a lot of discussion is likely to lead to a disappointment.

What makes good maintenance?

It’s not realistic to make a sweeping statement about how much it should cost to maintain an organ. Some instruments require weekly, even daily attention, especially if they’re large and complex, in deteriorating condition, and in use in sophisticated music programs. Some instruments require almost no maintenance. A newer organ of modest size with cone-tuning could go five years or more without needing attention.

I suggest that every organ should be visited by a professional organ technician at least once a year, even if no tuning is needed, even if every note plays perfectly, even if all the indicators and accessories are working. The lubrication of the blower should be checked, and the interior of the instrument should be inspected to guard against that one pipe in the Pedal Trombone that has started to keel over. If it’s not caught before it falls, it will take the pedal flue pipes with it. A four-hour annual visit would prevent that.

It’s usual for an organ to be serviced twice a year. While it’s traditional for those service visits to be before Easter and Christmas, at least where I live in the temperate Northeast, Christmas and Easter can both be winter holidays, so it makes more sense to tune for cold weather and hot weather, or for heat on, heat off.

Most organs do not need to be thoroughly tuned during every visit. In fact, starting over with a new “A” and fresh temperament every time can be counterproductive, unless it’s a very small organ. While the stability of tuning varies from organ to organ, most instruments hold their basic tuning well. I generally start a tuning by checking the pitch stops in octaves from the console, writing down a few that need tuning, and check the organ stop-by-stop for inaccuracies. I list a couple dozen notes that need tuning and a half-dozen stops that don’t need anything, and I list which reed notes (or stops) need to be tuned. In that way, I can build on the stability of tuning established over years, keeping the broad picture of tuning clear and concise.

Regular organ maintenance should include cleaning keyboards, vacuuming under pedalboards (the tuner keeps the pencils), checking blower lubrication, and noting larger things that will need attention in the future. Tuners, if you see cracks in a leather gusset on a wind regulator, make a note with your invoice that it will need to be releathered within several years. Your client doesn’t want to hear bad news, but they don’t want a sudden failure and emergency expense either.

When you should call

The better you know your organ, the easier to judge. I once received a panicky call from an organist saying the entire organ had gone haywire. He was abusive over the phone, and demanded that I come right away. I dropped everything and made the 90-minute drive to the church. Haughtily, he demonstrated the cause of his concern. It took me just a few seconds to isolate one pipe in the Pedal Clarion. If he had bothered to look, he could have played without the Clarion for weeks, but I couldn’t tell him that, and I’ve carried the memory of that unpleasant encounter for more than 30 years.

You should call your tuner/technician when:

• You hear a big bang from inside the organ. (Once it was a raccoon tripping a Havahart trap!)

• You hear unusual wind noise. (In some organs, a big air leak like a blown reservoir can lead to the blower overheating.) 

• You hear unusual mechanical noise, grinding, thumping, squeaking, etc.

• You find paint chips in organ areas. (Is the ceiling falling in?)

• The organ blower has been left on accidentally for a long time. It’s a long time for a blower to run between Sundays.

• And obviously, when something important doesn’t work.

When you should not call

Sudden changes in climate often cause trouble with the operation of a pipe organ. Several days of heavy rain will raise the humidity inside a building so Swell shutters squeak and stick, keyboards get clammy and gummy, and the console rolltop gets stuck. If you can manage, simply let the organ be for several days. When conditions return to normal, chances are that things will start working again. Likewise, excessive dryness can cause trouble.

A couple years ago, I was rear-ended in heavy traffic on the Hutchinson River Parkway in Westchester County, just north of New York City. I drive a full-size SUV and have a heavy-duty trailer hitch so while the Mercedes that hit me left a rainbow of fluids on the road under its crumpled radiator, the only damage to my car was that the back-up camera stopped working. As I’ve driven many hundreds of thousands of miles without one, I didn’t bother to get it fixed, and I’m still perfectly happy driving the car.

If there’s a dead note in the middle octave of the Swell to Great coupler, call me and I’ll fix it. It’s important to the normal use of the organ. If there’s a dead note in the top octave of the Swell to Choir 4′ coupler, and it’s spoiling a melody in a certain piece you’re playing, choose a different registration, or choose a different piece. One good way to head your church toward giving up on the pipe organ is to spend a lot of money on single repairs that don’t matter much to the music. Remember that your church pays me the same for mileage and travel time whether I’m doing a full service call with dozens of little repairs, or making a special trip for a single issue. A cipher is a bigger issue than a dead note.

It’s important to the long life of an organ not to “overtune.” Believe it or not, many churches in northern climes do not have air-conditioning, and it’s usual for temperatures to climb into the 90s inside the organ during the summer. If an organ was built, voiced, and tuned for A=440 at 70°, you’ll ruin the reeds—really ruin them—if you try to tune them to the Principals at 90°. It doesn’t make sense to wreck an organ’s reeds for one wedding, no matter who is the bride.

One of the most difficult tuning assignments I’ve had was at Trinity Church, Copley Square in Boston, in the early 1990s when Brian Jones, Ross Wood, and the Trinity Choir were making their spectacular and ever popular recording Candlelight Carols. It was surreal to sit in the pews in the wee hours of the morning, wearing shorts and a tee-shirt, sweltering in mid-July heat, listening to David Willcocks’s fanfare and descant for O come, all ye faithful. Everyone wanted the organ to be in perfect tune, but it was my job to be sure that the organ’s spectacular antique Skinner reeds would live to see another real Christmas. More than 200,000 copies of that recording have been sold, so lots of you have a record of that tuning!

§

Remember what I said about those dead notes that are a nuisance but not critical to the use of the instrument? The most important part of the organist’s role in organ maintenance is keeping a list. Maintain a notebook on the console, and write down what you notice. You might hear a cipher in the middle of a hymn that goes away. If you can pay attention enough to identify anything about it (what division, what stop, what pitch), write it down. If you think of a question, write it down. Maybe you noticed a tuning problem during a hymn. Write down the hymn number and what piston you were using. I’ll play the hymn and find the problem.

When I make repairs, I can check things off your list, write comments about the cause, make suggestions for future repairs or adjustments, and invite you for coffee the next time. The console notebook is the most important tool for maintaining an organ.

Notes

1. As I write, I’m thinking of the three clients where I owe follow-up. You know who you are.

2. I once found a little love nest inside an organ, complete with cushions, blankets, candles, and burnt matches. What could happen?

Shifty and puffy

It is mid-September in mid-coast Maine, and the days are getting shorter. Sunset here is about sixteen minutes earlier than in New York City, as we are as far east as we are north of the Big Apple. There are four windows facing east in our bedroom that allow us to track the motion of the sun, which is rising further south than it did a month ago. When we are on the water, we notice that the afternoon sun is lower in the sky as the sunlit water sparkles differently than in the height of summer. And the wind changes dramatically with the change of season. In mid-summer, we cherish the warm sea breeze, predominant from the south or southwest, caused by the air rising as it crosses the sun-warmed shore. All that cooler air above the ocean rushes in to fill the void, and we can sail for miles without trimming the sails in the steady and sure wind.

We had our last sail of the season last weekend in lumpy, bumpy wind from the northwest, which is never as steady as the southwesterlies. It is shifty and puffy, and it can be a struggle to keep the boat going in a straight line. Just as you get going, you get “headed” by a burst of wind from straight ahead, or you get clobbered abeam by a twenty-five mile-per-hour gust. Oof.

You have read this kind of thing from me before, thinking about sailboats when I should be writing about pipe organs, but because both are important parts of my life, and both involve the management of wind, I cannot escape it. And I am thinking about it a little more than usual because at the moment I am releathering three regulators for the organ I am working on. My method for assembling and gluing the ribs and frames of a wind regulator involves seven steps:

• Glue outside belts on the pairs of ribs.

• Glue inside canvas hinges on the pairs of ribs.

• Glue canvas hinges around regulator frames and bodies.

• Glue ribs to top frames.

• Glue ribs/top frames to body.

• Open regulator and glue gusset bodies.

• Close regulator and glue gusset tails.

It is still officially late summer as I write this, and my personal workshop is a three-car garage. Since we are on the shore, I love to have the overhead doors open to the breezes, though it is humid here. I am using the traditional flake hide glue (the stuff that is made when the old horse gets sent to the glue factory) that you cook in an electric pot with water, apply hot, and wipe clean with a hot-water rag that I keep just hot enough that I can put my hands in to wring the rag dry in the sort of double-boiler from which you scoop oatmeal at a cafeteria line. For the glue to set, the moisture must evaporate, and since the air is humid, I have to wait overnight between each step. Running fans all night keeps the humidity down and speeds the drying. In winter, when the air inside is dry, I can typically do two gluing steps in a day.

One of the regulators I am working on is thirty inches square. For that one I am using around twenty-five feet of one-inch-wide heavy canvas tape for the hinges and a comparable length of laminated rubber cloth for the outside belts. The gussets (flexible leather corner pieces) are cut from supple heavy goat skins that have a buttery texture and are impossible to tear. The key to finishing a wind regulator is finding a combination of materials that are all very flexible and strong, that are easy to cut, and that receive glue well enough to ensure a really permanent joint. If the structural integrity of a regulator is iffy, the wind will be shifty and puffy, and it will be a struggle to keep the music going in a straight line. Just as you get going, you get “headed” by a burst of wind that jiggles the music, or you get clobbered by a jolt from out of nowhere.

What’s in a name?

I am referring to these essential organ components as “regulators.” We also commonly call them “bellows” or “reservoirs.” All three terms are correct, but I think regulator is the most accurate description of the function of the thing. Taken literally, a bellows produces air. Air is drawn in when it is opened and pushed out when it is closed, like the simple bellows you have by the fireplace. The hole that lets the air in is closed by an internal flap when air is blown out.

A reservoir stores air. In an organ built before the invention of electric blowers, it was common for an organ to have a pair of “feeder bellows” operated by a rocking handle that blew air alternately into a large reservoir. The feeders had the same internal flaps as the fireplace bellows. The top of the reservoir was covered with weight (bricks, metal ingots, etc.) to create the air pressure, and the air flowed into the organ as the organ pipes consumed it. The bellows were only operated, and the reservoir was only filled when the organist was playing. Just try to get that kid to keep pumping through the sermon. . . .

With the introduction of the electric blower, it became usual to turn the blower on at the beginning of a concert or service and leave it running. That made it necessary to add a regulating valve between the blower and the reservoir. When the reservoir filled and its top rose, the valve closed, stopping the flow of air from the blower, so the system could idle with the blower turning and the reservoir full. When the organist played and therefore used air, the top of the reservoir would fall, the valve would open, and the air could flow again. Like before, there was weight or spring pressure applied to create the proper wind pressure. The addition of that valve added the function of pressure regulation to the bellows. In an organ with an electric blower, the bellows are storing and regulating the pressurized air. Calling it a regulator seems to cover everything.

The longer you go, the heavier you get.

Twice in my life, I have heard EMTs comment about my weight when lifting the stretcher, once after a traffic accident in the 1970s, and again after a fall in an organ seven years ago. But that is not what I am talking about here. We usually think of an inch as a unit to measure length or distance, so how can it refer to pressure, as in, “the Swell division is on six-inches of pressure?”

In industrial uses of pressurized air, more familiarly, in the tires or of your car, the unit of measure is pounds per square inch (PSI). I inflate the tires of my car to 35 PSI, and I use 80 or 100 PSI to operate pneumatic tools. But while my workshop air compressor gauges those high pressures, the actual flow is pretty small, something like two cubic feet per minute.

Organ wind pressure is much lower, and we measure it as “inches on a water column.” Picture a clear glass tube in the shape of a “U” that is twenty-inches high. Fill it halfway with water, and apply pressure to one side of the U. The water goes down on that side of the tube, and up on the other. Use a ruler to measure the difference, and voilà, inches on a water column, or centimeters, or feet. You can easily make one of these using plastic tubing. The little puff it takes to raise three inches of pressure is just the same little puff it takes to blow an organ pipe you are holding in your hand. Instead of the actual tube full of water, we use a manometer that measures the pressure on a gauge without spurting water onto the reeds.

Did you ever wonder how the conversion works? One PSI equals almost 28 inches on a water column. Five inches on a water column equals about .18 PSI. And how does that relate to the organs you know? In a typical organ, it is usual to find wind pressures of three or four inches. In general, smaller organs with tracker action might have pressures as low as forty millimeters, or less than two inches. In a three-manual Skinner organ, the Great might be on four inches, the Swell on six, and the Choir on five. In a big cathedral sized organ, solo reeds like French Horn and English Horn might be on fifteen inches, while the biggest Tubas are on twenty-five. The world-famous State Trumpet at the Cathedral of Saint John the Divine in New York City is on fifty inches (incredible), and in the Boardwalk Hall organ in Atlantic City, New Jersey, the Grand Ophicleide, Tuba Imperial, Tuba Maxima, Trumpet Mirabilis are on one hundred inches of pressure, or 3.61 PSI! Stand back. Thar she blows!

Once you have determined pressure, you also have to consider volume. A twenty-rank organ at three inches of pressure might need 1,000 cubic feet per minute at that pressure to sustain a big chord at full organ. Some of the largest organ blowers I have seen are rated at 10,000 CFM at ten inches of pressure. And when you lift the biggest pipe of a 32′ Open Wood Diapason and play the note as an empty hole, you will blow your top knot off. It takes a hurricane coming through a four-inch toehole to blow one of those monster organ pipes.

All the air you could wish for

Before the introduction of the electric blower, most organs had at least two bellows. One would be in free fall, supplying pressure to the organ while the other was raised by the organ pumper. The system I described earlier with two feeders and a reservoir was a great innovation, because once the reservoir was full, the pumper could slack off a little if the organist was not demanding too much wind. The six-by-nine-foot double-rise reservoir in the heart of a fifteen-stop organ by E. & G. G. Hook or Henry Erben has huge capacity, and can blow a couple 8′ flutes for quite a while without pumping. Organs by Hook are great examples of efficiency, with pipes voiced in such a way as to produce lots of tone with very little air, and even large three-manual organs are pumped by just one person using the two-feeders-and-a-reservoir system.

The electric blower changed everything. Organbuilders and voicers could now work with a continuous flow of wind at higher pressures than were available before. New styles of voicing were invented, and along with the introduction of electric keyboard actions, organs could be spread around a building, creating stereophonic and antiphonal effects. When organs were first placed in chambers, and their sounds seemed remote, the builders raised the pressure and increased the flow of air through the pipes, driving the sound out into the room.

While modest organs with electric blowers usually have only one wind regulator, larger instruments can have dozens. In a big electro-pneumatic organ, it is common to have a separate regulator for each main windchest. That is how Ernest Skinner could have the various divisions of an organ on different wind pressures, as each individual regulator can be set up to deliver a specific pressure.

But what about wiggly?

When I mention factors that can add to the stability of an organ’s wind system, I raise the question about “wiggly wind,” or “shaky wind,” both somewhat derogatory terms that refer to the lively flexible wind supplies in smaller and mid-sized mechanical action organs with lower wind pressure. When wind pressure is low and an entire organ receives its air from a single regulator, the motion of the wind can be affected by the motion of the music. It is especially noticeable when larger bass pipes are played while smaller treble pipes are sustained. At its best, it is a delightful affect, akin to the natural flow of air through the human voice. At its worst, it is a distraction when the organ’s tone wobbles and bounces.

This phenomenon is part of the fierce twentieth-century debate concerning “stick” organs versus so-called “industrial-strength” electro-pneumatic organs. I have been servicing organs for more than forty years, and I have often thought that much of the criticism of the emerging tracker-action culture was because craftsmen were reinventing the wheel, learning the art of organbuilding from scratch. They may have measured the dimensions of an organ bellows accurately but failed to compensate for the fact that the ancient model did not have an electric blower. And let’s face it: a lot of flimsy plywood tracker organs were built in the 1960s and 1970s, enough to give that movement a bad name from the start.

The evolution of modern tracker organs toward the powerful, thrilling, reliable, sonorous instruments being built today has much to do with how much the craft has learned about the management of wind over the years. A little tracker organ built in 1962 might have key channels and pallets that did not have the capacity to blow their pipes. It might have flexible wind conductors to offset bass pipes that were too small and that jiggled when the notes were played, causing the tone to bounce. It might have bass pipes with feet that were too short, so air did not have a chance to spread into a dependable sheet before passing between the languid and the lower lip. All of these factors affect the speech of the pipes, giving the impression that the organ is gasping for air. And worse still, you might hear the pitch drop each time you added another stop. I have worked on organs where adding an 8′ Principal made the 4′ Octave sag. How do you tune a thing like that? I marvel now at how air pressure moves through the best new tracker organs, especially at the wonderful response of large bass pipes. Organs by builders like Silbermann do not lack in bass response. Once the revival movement was underway in the middle of the twentieth century, it took a few decades to really start getting it right.

The organ I am working on today is a simple little thing with two unit action windchests. Each has its own regulator, and there is a third “static” regulator that mounts next to the blower. The blower produces seven inches of pressure; the static regulator brings it down to five inches and distributes the wind to the other two regulators, which each measure out four inches. The biggest pipes in the organ are the 16′ Bourdon, and though there are only ten ranks, it is a unit organ, and a lot of pipes can be playing at once. It is destined to be a practice instrument for a university organ program, so I know that talented and ambitious young organists will be giving it a workout as they learn the blockbuster literature we all love so much. I hope that those students never have to worry about having enough air. And perhaps Maine’s salty breezes will travel with the organ, adding a little flavor to the mix.

Sounds of the natural world

We have counted about sixty-five different species of birds in our yard in Maine. We have ruby-throated hummingbirds (3 inches long and .1 ounce), great blue herons (52 inches long and 51⁄2 pounds), and bald eagles that weigh in at around 12 pounds, have wing spans over 7 feet, and dive to the water at 100 miles per hour, miraculously surfacing with a fish in their talons. We have five different varieties of gulls (greater black back, lesser black back, herring, laughing, and Bonaparte’s gulls), and five of woodpeckers (downy, hairy, red-bellied, flicker, and pileated woodpeckers). We have crows, lots of crows, but we also have their goth-heavy metal cousins, the ravens.

We have half a dozen different bird feeders around the yard, so we see lots of our birds up close. Except for the pileated woodpeckers that are too big, all our woodpeckers come to the suet feeders on the deck, next to the hummingbird feeders that are the sites of pugnacious air battles. There is a definite pecking order among hummingbirds.

Recently, son Christopher and his sons, Ben and Sam, came for a weekend. We were sitting on the deck one evening, and five-year-old Ben started noticing the variety of birds coming and going from the feeders just outside the screen. I identified some of them for him and told him a little of what I know about them. Pretty soon he was identifying the birds himself as they returned to the feeders. I brought out a field guide, and Ben and I sat at a table on the deck for a full hour looking at the pictures and reading about the birds we were seeing, getting the hang of understanding the range maps, looking further into birds we might see in the area, and those we would never see here. The following morning, Ben picked up the guide and sat down with me for another hour. In an age when parents struggle with the “screen issue,” trying to find a balance between staying current and staving off addictions, those were a couple hours I will never forget.

The weekend after that visit, they all went camping. Chris sent a photo of Ben with field guide in hand, working hard to identify some slithery creature that another kid had in a plastic container. I do not know if this curiosity about the natural world will last long, but for now, Grandpa sure is pleased to share something special with a bright young mind.

Taking a glimpse into the natural world with my grandson refreshed my awareness of all that lives around us. (As I write, I am watching a pileated woodpecker tear up a tree, chips flying and insects scurrying.) And I do not have to be in Maine to be a witness. Last year I joined a group of New York University students in Washington Square Park watching a red-tailed hawk sitting in a tree eating a squirrel.

When I write of birds, many readers will think instantly of Olivier Messiaen, that giant of twentieth-century music who was so inspired by birdcalls. In earlier works, Messiaen included stylized, even perhaps fictional birdcalls in his music. At the Paris Conservatoire, Messiaen was a student of Paul Dukas, who encouraged all his students to “listen to the birds,” a suggestion that informed much of Messiaen’s music and life. He traveled the world notating birdcalls, accompanied by his second wife, Yvonne Loriod, who made tape recordings to back up her husband’s pen. And the calls that he collected are present in much of his music, often as direct quotes, and often as the primary substance of entire pieces.

One of Messiaen’s great works is his Catalogue d’Oiseaux (Catalogue of Birds), a suite of thirteen pieces for solo piano, each inspired by a different specific bird. The French pianist Pierre-Laurent Aimard presented this work in a unique series of performances at the Aldeburgh Festival in 2016. He programmed four concerts based on the time of day that the various birds are active, and played them outdoors, allowing the audiences to hear the local birds comment on the music. The first of those concerts started at 4:30 a.m., the very hour when crows start hollering in our yard in Maine. Aimard was a student of Yvonne Loriod, Messiaen’s widow, who performed the premier of the work, and to whom the music is dedicated, and he must have had many inspiring conversations with her about this great piece. You can read Michael White’s New York Times review of those performances at https://www.nytimes.com/2016/06/22/arts/music/review-pierre-laurent-aim….

Follow the nuts.

Watching birds on the deck with Ben was fun for me, but there is another level of that activity, better known as “birding.” I know lots of people who can be called “organ nuts,” and many of those are also “train nuts,” so colleagues are well equipped to understand that rare breed of nut, birders. If you are hiking in a state park and run into a group of people with floppy hats, lots of pockets on their clothes, $2,500 binoculars (a.k.a. “binos” or “bins”), and camera lenses the size of howitzers, it is a safe bet that they are birders.

There are nearly a thousand different species of birds in the United States, and serious birders set off to site as many as they can in a single year. It is called a “big year” as hilariously chronicled by Steve Martin and Jack Black in the 2011 movie by that name. For most serious birders, a big year consists of 675 species. A new record of 749 was set in 2013, which was shattered in 2016 by four different people, with the highest tally at a whooping, oops, whopping 780. Because many birds are season and site specific, achieving a big year involves intricate planning and tens of thousands of miles of travel. In these adventures, identifying a bird by sound counts as a sighting, whether or not you actually laid eyes on the creature.

Most birds have several different distinct calls. There are multi-syllabic calls and warbles, and one-tone “notes,” and they are as different aurally as the birds can be visually. You would never mistake the “pew-pew-pew” of a cardinal with the raucous “caw-caw” of a crow. The raven’s call is similar to the crow’s, but down a fifth and dripping with attitude. Robins sing a rhythmic series of warbles, as do goldfinches, but the goldfinch’s song is an octave and a half higher. The song of the rock dove (a.k.a., pigeons) is a characteristic chuckling cooing while her demure cousin, the mourning dove, produces a similar tone quality, but in an ordered and measured cadence.

Any field guide includes page after page of sparrows that all look alike. They are distinguished by features like a little brown mark behind the eye, a black stripe on the crown, or a tuft of brown on the white belly. Even serious birders refer to “LBJ’s”—little brown jobs. But their songs are much more distinctly different from each other. You would never mistake the multi-octave swirl of the song sparrow from the dry trill of the chipping sparrow.

One of the more beautiful calls we hear at our place is that of the hermit thrush. It is an otherworldly, hollow trilling, easy to pick out near sunset in the woods to the north of our driveway. When you record it and play it back slowly, you can distinctly hear two different lines of music. And even more exciting, the various pitches are related to each other by the overtone series. Three cheers for Pythagoras!

All birds have a sound-producing organ called a syrinx, a two-piped structure capable of producing two pitches simultaneously. The various types of thrushes, which include our locally admired veery, have all developed complex songs that exploit the contrapuntal capability of the syrinx to the fullest. The world of birds brings one of the richest varieties of musical tone on earth.

§

The ancient Greeks and Romans each developed complex systems of gods and myths in efforts to explain natural phenomena they did not understand. We are all familiar with Zeus, the cranky and irascible god of the sky and thunder. The iconic image of a heavy bearded dude with a quiver full of lightning bolts was enough to make a humble farmer behave himself.

A Greek myth tells of Syrinx, a chaste nymph who was chased by the leering and persistent Pan. In an effort to escape, she ran to the edge of a river and pleaded to the other nymphs to protect her. In response, they turned her into hollow grasses that made haunting whistles when the frustrated Pan’s breath hit them. Pan cut the grasses to different lengths and fastened them together, making a musical instrument on which he could play tunes. From legend into reality that instrument was called, wait for it, the panpipe, or in ancient Greek, the Syrinx. (The word syringe is derived from the same root.)

The panpipe is the ancient forerunner of the pipe organ, so we have a mythical connection between birdcalls and the organ. All are wind-produced sounds. Different species of birds have hollow cavities like sinuses, specially evolved echoing bone structures, and other physiological features to help project their calls. The hermit thrush is a pudgy LBJ with a peppered white breast, less than seven inches long and weighing just a few ounces, but its call is heard clearly hundreds of feet away.

As the lusting Pan chased Syrinx to the bank of the river, to be rewarded only by the invention of a musical instrument, I wonder how many early musicians and craftsmen were inspired by birds to develop more sophisticated varieties of tone color.

Listen.

Over centuries, organbuilders have developed countless different organ stops, each distinguished from the next by the shapes and dimensions of their pipes. An experienced organbuilder, voicer, or tuner will automatically call up the characteristic sound of an English Horn when seeing the equally characteristic “Choo-choo Train” at the top of the resonator. Listen to a recording of colorful organ music or during a live performance and see how many different individual stops you can identify. How would you describe the difference between the timbre of that English Horn and an Oboe or Clarinet? In your mind’s ear, do you know the differences between those stops?

It is more difficult to identify by ear the stops that make up a big chorus, unless you are familiar with the given instrument. In the pews or on a recording, it is easy to tell that you are hearing a principal chorus, but is there an 8′ flute playing that darkens the chorus just a little? Maybe (watch out for lightning bolts) even a 4′ flute?

Turn that story around. You are sitting on the bench of an organ that is new to you, ready to register a familiar piece. Do you draw the same list of stops that you used last week on a different organ? Do you decide you cannot play that piece on this organ because there is no Tierce? You have an idea in your mind’s ear about how that piece could or should sound. Find the combination that comes closest to that. Or, find a completely different combination that sounds good. No one is insisting that the Mixture has to be on all the time. Choosing stops, especially on a well-balanced organ of good size, is one of the great freedoms granted to organists.

If adding an 8′ flute to a chorus is a subtle change for the listener, it is a magic ingredient for the organist, something like a dash of turmeric to make a subtle change in a recipe. It is actually a gift to the listener, because the chorus at the beginning of the fugue is just a little different from that at the beginning of the prelude or toccata. Some trained listeners might notice that, but with any luck, you will have lots of untrained listeners in the pews. Your subtle touches of registration will make your program more interesting. No one wants to listen to the same 8′-4′-2′-IV all afternoon, no matter how much they know about organ sound. Color those basic-four with a light reed, with a Quint, with a flute or two. Go ahead. I dare you.

Do you recognize the difference between the sound of a wide-scaled principal and one with narrow scale? Echoing the early twentieth century, it is increasingly common today to find two, three, or even four different 8′ principals on a single keyboard division. Why is that? Is not one enough? For how long would you gaze at a painting by Rubens if every time he used red he used the same red?

I was taught a few rules of registration in my first organ lessons. For example, it was suggested that you should not use a 4′ flute over an 8′ principal. Fair enough, you might say. But what if it sounds good? You are not going to be pulled over and given a ticket for playing in a “no flute” zone.

The listening organist can spare the listeners another ignominy. You draw a couple stops and start to play, and it sounds awful. Why? The cap of middle D-sharp of that Gedeckt has slipped and the pipe speaks drastically sharp. Do not use that stop. Couple the Postiv chorus to the Great, and you hear a great clashing clang. It might be that the exposed Positiv is surrounded by warmer air than the Great. When the sun goes down it might be fine. But for now, not so much. Turn off the coupler and find another sound.

The best performances of organ music come from musicians who listen as they play. If you do not want to listen, why should your audience?

I leave you with another lovely episode from grandson Ben. His parents took him to early life music lessons that included introductions to lots of instruments. (He has a pretty good embouchure for the copper-hunting trumpet we have on the mantle.) In a recent visit, he and I sat together at the piano for twenty or thirty minutes. I taught him the names of the notes, how to find “C” (just to the left of the group of two black notes), and a little about how scales work. I asked what songs he knows, and he quickly gave me “Twinkle, twinkle.” I played the tune in the key of C and showed him how you can play it in different keys using scales based on different notes. I compared major and minor scales, and then played “Twinkle, twinkle” in the minor. He furled his little five-year-old brow, “Oh, Grandpa, that’s a very dark ‘Twinkle, twinkle.’”
