The Positif

The Positif is the organ's second voice, the counterpart to the Grand-Orgue, and in the French tradition it occupies a position that is both architecturally and musically distinct — the Positif case stands at the front of the gallery, at the railing, between the organist and the nave, so that its sound projects directly into the building while the Grand-Orgue's sound projects from behind the organist, reflected off the back wall of the gallery before it enters the nave, and this difference in projection gives the two divisions different characters that have nothing to do with their voicing: the Positif is direct, immediate, close; the Grand-Orgue is reflected, spacious, distant. The Positif speaks to the listener. The Grand-Orgue speaks to the room.

Her father had designed the Positif with twelve stops, a complete division capable of standing alone as a small organ or combining with the Grand-Orgue to provide the full-bodied sound the French repertoire demanded, and the stoplist was classical — Principal 8', Bourdon 8', Prestant 4', Flute 4', Nasard 2-2/3', Doublette 2', Tierce 1-3/5', Larigot 1-1/3', Fourniture III, Cromorne 8', Trompette 8', Clairon 4' — a specification that could have been drawn from a seventeenth-century Clicquot or an eighteenth-century Isnard, the stops arranged to provide the Cornet decompose, the combination of foundation stop plus Nasard plus Doublette plus Tierce that was the signature sound of the French classical organ, a combination that produced a bright, nasal, penetrating tone used for the solo voice in the dialogues and trios that were the glory of the French Baroque repertoire.

The voicing notes for the Positif were less elaborate than those for the Grand-Orgue. Her father had written shorter annotations, as if the Positif's character was more obvious to him, less in need of the private language he had used for the larger division. The Principal 8' was marked "le voisin" — the neighbor. The Bourdon 8' was marked "la maison" — the house. The Nasard was marked "la question." The Cromorne was marked "le rire" — the laugh.

These were warmer words than the Grand-Orgue's annotations, more human, less geological, as if the Positif division existed in the domestic sphere while the Grand-Orgue existed in the cosmic, and Marguerite thought this was consistent with the Positif's musical role, which was intimate rather than monumental, the division the organist used for accompanied solos and chamber-scale textures, the division that spoke to the listener at a human scale rather than an architectural one.

She began with the Principal 8', "le voisin," and the voicing was different from the Grand-Orgue Montre — the Positif Principal was narrower in scale, which gave it a more focused, more personal sound, and the Positif case's direct projection into the nave meant the sound arrived at the listening point with less mediation, less room processing, the pipe's voice more exposed, more naked, and Marguerite had to voice with this exposure in mind, reducing the power and increasing the refinement, because a pipe that sounded full and warm on the Grand-Orgue's reflected sound path would sound harsh and overpowering on the Positif's direct path, the acoustic difference between speaking into a room and speaking into a face.

She learned this in the first hour. The first Positif pipe she voiced — the Principal 8' middle C — sounded, from the gallery, almost identical to the Grand-Orgue Montre middle C, the same warmth, the same clarity, the same gentle chiff. But when Helene played it and Marguerite listened from the nave, the sound was different — brighter, more present, more immediate, the directness of the Positif case projecting the pipe's voice into the nave without the softening that the Grand-Orgue's reflected path provided, and the result was a tone that was not harsh but was assertive in a way the Montre was not, and assertiveness was not the quality of a neighbor, a "voisin," a neighbor being someone who was present but not intrusive, nearby but not close, and Marguerite went back to the gallery and reduced the pipe's power by narrowing the flue and raising the cut-up, darkening the sound by a degree, reducing the upper harmonics, and when Helene played the note again the sound at the listening point was gentler, more companionable, the Principal speaking as a friend speaks rather than as a preacher speaks, the volume appropriate to a conversation rather than to a declaration.

This distinction — the Positif as conversation, the Grand-Orgue as declaration — became the governing principle of the Positif voicing. Each stop was voiced to be compatible with the Grand-Orgue's stops but not to compete with them, the Positif's role being complementary rather than rival, and the voicing reflected this by keeping the power lower, the attack softer, the harmonic content rounder, so that when the two divisions were played together — the Grand-Orgue providing the body and the Positif providing the clarity — the result was a sound that was both spacious and defined, both large and detailed, the combination achieving what neither division could achieve alone.

The Nasard was the stop that interested her most, because the Nasard was the stop that had interested her father most, the mutation at the twelfth that gave the French organ its nasal color, and her father had written beside it the word "la question," which she found both apt and mysterious — apt because the Nasard's pitch, a twelfth above the fundamental, was inherently unstable, the fifth being the interval of questioning, the interval that pulled away from the tonic and demanded resolution, and mysterious because a stop was not a question, a stop was a sound, and a sound did not ask, it stated, and the notion of a questioning sound was either poetic or paradoxical and she was not sure which.

She voiced the Nasard on a Tuesday afternoon in late April, the cathedral warm for the first time since the installation, the spring heat entering through the open clerestory windows and raising the temperature in the nave by several degrees, which changed the acoustic — warmer air was less dense than cooler air, and less dense air transmitted sound slightly faster, which meant the pipes sounded very slightly sharp compared to their cold-weather tuning, a drift of a few cents that the ear did not detect as a pitch change but that the body detected as a change in the quality of the space, the cathedral feeling different in the warm, the sound traveling differently, the reverberation slightly shorter because the warmer air absorbed more energy, and Marguerite noticed this and filed it away as information she would need when tuning, the knowledge that the organ would sound different at different temperatures and that the tuner's job was to find the compromise that sounded acceptable across the range, not perfect at any single temperature but good at all temperatures.

The Nasard pipes were small — the middle C pipe only thirty centimeters long, a cylinder of tin-lead alloy with a mouth one-quarter of its circumference and a flue so narrow that the mandrel she used to adjust it was the smallest in her kit, a tool barely larger than a needle — and the sound they produced was correspondingly small, a thin bright tone that by itself was almost unpleasant, a whine, a nagging insistence at the pitch of the twelfth, a pitch that the ear could not integrate with the fundamental without effort, and the effort was the point, the Nasard's purpose being not to produce a pleasant sound alone but to contribute a harmonic that, when combined with the fundamental and the other harmonics of the Cornet combination, produced a tone of extraordinary complexity and brilliance, the kind of tone that the French Baroque composers had in mind when they wrote their dialogues and trios, a tone that could carry a solo melody over a full accompanying texture with a clarity that cut through everything.

She voiced the Nasard pipes to speak promptly and clearly, the attack clean, the tone steady, the pitch accurate, and when she combined the Nasard with the Principal 8' and the Doublette 2' and the Tierce 1-3/5' — the Cornet decompose — and Helene played a melody from the nave she heard the sound she had been building toward, the classical French solo combination, the bright nasal singing tone that was unlike any other sound in the organ and unlike any other sound in music, a tone that was both ancient and alive, both familiar and strange, the sound of an instrument that had been refined over four centuries by hundreds of builders and thousands of organists and that arrived at Marguerite's ears in the nave of the cathedral with a rightness that was not hers but was the tradition's, the sound correct not because she had made it correct but because the tradition had defined what correct meant and she had followed the tradition, and the following was not a failure of originality but an act of membership, an acknowledgment that she belonged to a lineage of builders who had made this sound before her and who had passed the knowledge of how to make it from hand to hand and ear to ear across the centuries.

"La question." She heard it now. The Nasard's pitch, the twelfth, was the question in the Cornet combination — the harmonic that pulled the tone away from the fundamental and toward the dominant, the harmonic that introduced tension, the harmonic that made the sound lean forward rather than settle back, and this forward lean was the question, the implication that the sound was going somewhere, that it had not yet arrived, that the melody carried by the Cornet combination was a melody in motion, seeking its resolution, and the resolution would come when the organist changed the registration, when the Nasard was retired and the Principal chorus took over, the question answered by the simple, stable, grounded sound of the plenum.

She marked the Nasard complete: "La question. Oui."

The Cromorne was the last stop she voiced on the Positif before moving to the Recit, and it was the first reed stop she voiced for the organ, and the first reed was always significant because the reeds established a different sonic world within the instrument, a world of vibrating brass rather than vibrating air, of tongues rather than lips, of sound that was produced by a mechanical oscillation rather than by an aerodynamic one, and the transition from flue voicing to reed voicing was a transition she always felt in her body, a shift in attention from the gentle adjustments of the flue — opening, closing, smoothing — to the precise, sometimes forceful adjustments of the reed — curving the tongue, shaping the shallot, setting the wedge, tuning by moving the wire that held the tongue to the shallot — each adjustment more consequential because the reed was more sensitive, a small change in tongue curvature producing a large change in tone, the reed amplifying the voicer's touch in a way the flue did not.

Her father had written beside the Cromorne: "le rire" — the laugh. The Cromorne was a short-resonator reed, meaning its resonator was half the length of a full-length reed like the Trompette, and this half-length resonator gave the Cromorne a nasal, buzzing tone that was distinct from the Trompette's broad clarity, a sound that was often described as reedy or pungent or, in the vocabulary of wine, as having "character," which was a polite way of saying it was not beautiful in the conventional sense but was interesting, assertive, memorable, the kind of sound that lodged in the ear and refused to leave.

"Le rire." She thought about this as she voiced the first Cromorne pipe — the middle C, a brass tongue vibrating against a brass shallot inside a tin boot beneath a half-length tin resonator — and she adjusted the tongue's curvature until the pipe spoke with a sound that was bright and buzzy and slightly aggressive, the Cromorne's traditional character, and then she refined the character, softening the attack by reducing the tongue's curvature at the tip, where the tongue first contacted the shallot, so that the speech began not with a hard consonant but with a softer one, a "br" rather than a "kr," and the softer attack gave the sound a quality that was — she heard it as she listened from the nave — amused. The Cromorne sounded amused. Not laughing, not jovial, but wry, the way a person who has seen many things sounds when they describe something unexpected, the tone carrying a humor that was not in the pipe's physical properties but in the relationship between the pipe's properties and the listener's expectations, the Cromorne sounding different from what the listener expected a reed to sound like, and this difference was the humor, the surprise, "le rire," not a belly laugh but a wry smile, a sound that acknowledged the absurdity of a brass tongue trying to sing in a stone cathedral and that found the absurdity amusing rather than tragic.

She voiced the Cromorne rank in four days, each pipe adjusted to share the quality of the first, the wry warmth maintained across the scale, and when Helene played the completed rank Marguerite heard something she had not heard in an organ before — a stop that sounded like a personality, not like an imitation of an instrument or a voice but like a character, a person in the room who had opinions and a sense of humor and who expressed both through the sound of vibrating brass, and she thought that "le rire" was exactly right, that her father had identified the Cromorne's essential nature with a single word, and that the word had guided her voicing without constraining it, the way a title guides the reading of a book without determining its meaning.

She sat on the gallery step that evening and wrote in the notebook, beside her father's annotation: "Le rire. Oui. Mais aussi le sourire." The laugh. Yes. But also the smile.

She closed the notebook and looked at the organ, the Positif case below her at the gallery railing, its pipes gleaming in the last light from the nave windows, and the Grand-Orgue case behind her, its pipes hidden in the shadows of the case interior, and she thought about the two divisions and the two characters — the Grand-Orgue cosmic and the Positif domestic, the Grand-Orgue speaking to the room and the Positif speaking to the listener — and she thought that the organ was becoming an instrument with a personality that was neither hers nor her father's but something that emerged from the combination of his design and her voicing and the cathedral's acoustic, the three collaborators producing a result that none of them could have produced alone, and this result was the organ that was waiting to be heard, the organ the notebook had promised, and it was beginning to speak.
