The Recit

The Recit expressif is the organ's enclosed division, the division housed inside a wooden box with movable shutters that the organist controls with a foot pedal, and the shutters function like eyelids — when they are closed the sound is muffled, soft, distant, and when they are open the sound is clear, full, present, and the gradation between closed and open gives the organist a dynamic range that the other divisions do not have, because the other divisions speak at a constant volume determined by the voicing and the wind pressure, and the only way to change their volume is to add or subtract stops, which changes the color as well as the volume, while the Recit's shutters change the volume without changing the color, the same stops sounding louder or softer depending on the position of the shutters, and this dynamic control is what makes the Recit "expressif," the division that can swell and diminish, that can crescendo and decrescendo, that can breathe.

She built the swell box before voicing the Recit pipes, because the box was part of the acoustic — the pipes would sound different inside the box than outside it, the box's internal reflections and absorptions coloring the sound before it passed through the shutters, and voicing the pipes without the box would be voicing for the wrong acoustic, the same mistake as voicing in the workshop for the cathedral, only worse because the box was closer to the pipes and its effect was more immediate.

The swell box was a structure of pine, three meters long and two meters wide and two meters tall, assembled on the gallery from panels she had prepared in the workshop, each panel a sandwich of pine boards with a layer of wool felt between them, the felt providing acoustic isolation that prevented the Recit's sound from leaking through the box walls into the other divisions, because a swell box that leaked would defeat its own purpose — the shutters would open and close but the sound would escape around them, and the dynamic range would be reduced to a suggestion rather than a reality, the difference between open and closed barely audible, and a barely audible dynamic range was the same as no dynamic range at all.

She built the shutters — twelve horizontal slats of pine, each one running the full width of the box's front face, each slat pivoting on pins at its ends so that it could rotate from closed to open, the slats linked by a vertical rod that connected to a horizontal tracker that ran under the gallery floor to the swell pedal at the console, and when the organist pressed the pedal the rod pulled the slats open in sequence, from bottom to top, the sound emerging first from the bottom of the box and then, as the pedal was pressed further, from the full face, and the graduation of opening gave the organist control over not just the volume but the character of the sound, because the bottom slats projected into the nave while the top slats projected into the vault, and the two paths produced different qualities of sound at the listening point, the bottom path more direct and the top path more reflected, and the mix between them changed as the shutters opened, so that the Recit's crescendo was not merely a change in volume but a change in the spatial character of the sound, the division seeming to move forward as the shutters opened and to retreat as they closed, an effect that was partly acoustic and partly psychological, the opening of the shutters releasing the sound from its enclosure and the closing returning it, the listener perceiving the change as a movement in space rather than a change in amplitude.

The voicing of the Recit was the most delicate work she had done. The division's stops were designed for expression — soft flue stops that could whisper when the shutters were closed and sing when they were open, and warm reed stops that could murmur behind the shutters and blaze when released — and each stop had to sound beautiful at both extremes, at the closed position where the sound was reduced and distant and at the open position where the sound was full and present, and the voicing had to account for both conditions simultaneously, a balance that required the pipes to be voiced with a particular sensitivity, not too loud for the closed position and not too soft for the open, and not too bright for either, because brightness was the quality most affected by the shutters, the high frequencies being more directional than the low, more easily blocked by the closed slats, so that a bright pipe would sound dull behind closed shutters and bright behind open ones, the range of color too wide for the ear to accept as a single stop, and Marguerite had to find the middle ground, a degree of brightness that was warm enough to sound good when muffled and clear enough to sound good when released.

Her father's notes for the Recit were the most lyrical in the notebook. The Gambe 8' — a narrow-scaled string stop that produced a thin, intense tone — was marked "le fil" — the thread. The Voix Celeste 8' — a second string stop tuned slightly sharp to beat against the Gambe, producing the undulating tone that was the Romantic organ's signature — was marked "le frisson" — the shiver. The Flute Harmonique 8' — an overblowing flute of great purity — was marked "le ciel" — the sky. The Hautbois 8' — a reed stop imitating the orchestral oboe — was marked "la nostalgie."

These were the Recit's colors, and they were Romantic colors, the palette of the nineteenth-century French organ that Cavaille-Coll had defined and that every French builder since had either continued or reacted against, and her father had continued it, the Recit specification being almost pure Cavaille-Coll, a division designed for the repertoire of Franck and Widor and Vierne, the symphonic organ music that treated the instrument as an orchestra and the organist as a conductor, and the Recit was the orchestra's string section, the section that could swell and diminish and that provided the emotional center of the symphonic texture.

She voiced the Gambe 8' first — "le fil," the thread — and the Gambe was a challenge because narrow-scaled pipes were difficult to voice, the narrow body amplifying every imperfection in the mouth geometry, a Gambe pipe that was almost right sounding not almost right but distinctly wrong, the narrow scale acting as a magnifier of error, and Marguerite spent two full days on the Gambe middle C alone, adjusting and listening and adjusting again, the pipe resisting her, refusing to settle into the thin intense tone the Gambe was meant to produce, instead giving her a sound that was either too thin — a whistle, a screech — or too fat — a small Principal, lacking the Gambe's distinctive edge — and she could not find the middle, the thread, the narrow path between the two extremes.

She went back to the notebook. The specifications for the Gambe were detailed: very narrow flue, low cut-up, no nicking, no ears, light wind pressure. She had followed these specifications exactly and the pipe was not cooperating. She closed the notebook and sat on the gallery step and looked at the pipe, which stood on the voicing machine mute and uncooperative, and she thought about what her father would have done.

Her father would have listened. Not to the pipe — the pipe was not speaking — but to the silence around the pipe, the acoustic conditions in which the pipe was being asked to speak, and Marguerite realized that she had been voicing the Gambe on the gallery, where the acoustic was dry and close, but the Gambe was a Recit stop and the Recit stops spoke inside the swell box, and the swell box was a different acoustic from the gallery, a smaller space with more reflections, and the pipe needed to be voiced inside the box, where the sound it produced would be the sound the shutters would modulate, and voicing it outside the box was voicing it for the wrong room.

She installed the Gambe on the Recit wind chest, inside the swell box, and closed the shutters and went down to the nave and Helene played the note.

The sound that came through the closed shutters was a thread. A thin, pure, intense line of sound that emerged from the swell box like a filament of light through a crack, and the thread was steady and even and had the quality her father had described — "le fil" — the continuous, almost invisible line that connected two points, in this case the pipe and the ear, the sound traveling from its source through the box and through the shutters and through the air of the nave to the listening point, reduced by every barrier but not destroyed, still present, still audible, still carrying the Gambe's distinctive intensity, and Marguerite stood at the brass disc and listened and thought: the box is part of the voicing. The enclosure is part of the instrument.

She had been thinking of the swell box as a container, a housing for the pipes, but it was more than that — it was an acoustic modifier, a room within a room, and the Recit pipes needed to be voiced for this room, not for the gallery, and the voicing would be different because the room was different, and this was a lesson she should have known but had not applied until the pipe forced her to, the Gambe's refusal to speak on the gallery being not a defect in the pipe but a defect in the voicer's approach, and the defect was corrected not by adjusting the pipe but by adjusting the context, by putting the pipe where it belonged and letting the context do what the voicer could not.

She voiced the remaining Gambe pipes inside the swell box, each one installed on the wind chest and heard through the shutters, the voicing done by running up and down the staircase between the nave and the gallery — listening from below, adjusting from above, listening again — and the process was slow and physical and exhausting, the staircase steep and narrow and cold, but the results were right, each pipe producing the thread-like tone that was the Gambe's character, and the character was consistent across the rank, the thread maintained from bottom to top.

The Voix Celeste was next — "le frisson," the shiver — and the Voix Celeste was not a separate stop but a second rank of Gambe pipes, tuned slightly sharp, so that when both stops were drawn the two ranks beat against each other, the slight difference in pitch producing a slow undulation in the sound, a tremolo that was not mechanical but acoustic, produced not by a device that varied the wind pressure but by the interference between two almost-identical frequencies, and this acoustic tremolo was the most beautiful effect in the Romantic organ, a shimmer in the sound that was both regular and alive, regular because the beat frequency was constant and alive because the two ranks were not perfectly consistent across the scale, the tuning varying slightly from pipe to pipe, so that the tremolo had a complexity that a mechanical tremblant could not achieve.

She tuned the Voix Celeste to beat at approximately one and a half cycles per second — the traditional French tremolo speed, slow enough to be perceived as a shimmer rather than a wobble, fast enough to be heard as a continuous effect rather than a series of discrete pulses — and when Helene drew both stops and played a chord, the sound that came through the closed shutters was a shiver, a gentle oscillation of tone that filled the nave with a warmth that was almost physical, a caress of sound, the two ranks breathing against each other in a rhythm that was too slow for music and too fast for stillness, a rhythm that was the speed of contemplation, of thought, of the slow emotional processing that music at its best facilitates.

"Le frisson." She wrote in the notebook: "Oui."

The Flute Harmonique — "le ciel," the sky — was a pipe of a different construction, an open metal flue pipe with a small hole drilled in the side at the midpoint, which caused the pipe to overblow, to sound at the octave rather than the fundamental, and the overblown sound was pure, almost sinusoidal, the harmonics suppressed by the overblowing, leaving only the fundamental and a faint second harmonic, and the result was a sound of extraordinary clarity and purity, a sound that seemed to exist above the other stops, floating, weightless, the acoustic equivalent of sky, of the blue that exists above everything and contains nothing, and Marguerite voiced the Flute Harmonique with the lightest touch she had used on any stop, the adjustments minute, the flue barely open, the cut-up high, the pipe speaking with a reluctance that was not sluggishness but gravity, the sound taking a moment to lift off the way a bird takes a moment to leave the ground, and once airborne the sound was free, was sky, was "le ciel."

The Hautbois — "la nostalgie" — was a reed stop that imitated the orchestral oboe, and the imitation was close enough to be recognizable and far enough to be its own thing, the organ's Hautbois having a nasal brightness that the orchestral oboe shared but also a steadiness that the oboe did not, the organ pipe sustaining indefinitely while the oboe's note decayed with the player's breath, and this steadiness was what gave the organ's Hautbois its particular quality, the sound of a voice that does not run out of breath, that can hold a note forever, and this permanence was both the Hautbois's strength and its sadness, because a note that does not decay is a note that does not breathe, and a note that does not breathe is a note that is not alive in the way that the oboe's note is alive, and the sadness of this permanence was "la nostalgie," the longing for the living breath that the organ could not have.

She voiced the Hautbois with her father's notes open beside her, the specifications detailed and precise — tongue curvature three degrees, shallot opening seven millimeters, resonator bell flare fifteen degrees — and the pipe spoke with a sound that was indeed nostalgic, a thin warm reed tone that floated behind the closed shutters like a voice in another room, a voice you could hear but not reach, and when Helene opened the shutters with the swell pedal the Hautbois's voice came forward, closer, clearer, but still unreachable, still separate, the nostalgia not erased by proximity but deepened by it, the way seeing a photograph of a person you have lost does not reduce the loss but sharpens it.

She completed the Recit voicing in three weeks, each stop voiced inside the swell box, each stop tested at both extremes of the shutters, the division becoming the organ's emotional center, the place where the sounds lived that were too private for the Grand-Orgue and too tender for the Positif, and when Helene played the complete Recit — all the stops drawn, the shutters opening slowly from closed to open — the sound was like a room opening, like a door swinging wide on a space you did not know was there, and behind the door was everything the organ had not yet said, the thread and the shiver and the sky and the nostalgia, the Romantic palette in its full range, from the whispered Gambe behind closed shutters to the blazing Trompette with shutters wide, and Marguerite stood in the nave and listened to the sound swell and recede and swell again and she thought that the Recit was the division that most clearly belonged to neither her father nor herself but to the organ, the instrument finding in the enclosed space of the swell box a privacy that allowed it to speak without the self-consciousness of the exposed divisions, the shutters protecting the sound the way walls protect a conversation, and the sound that emerged through the shutters was the sound of the organ talking to itself, the inner voice that the listener was permitted to overhear.
