Yuki

The Equal Temperament

Chapter 3: Yuki

Yuki Tanaka arrived at Clara's house on Wednesday morning at nine o'clock, which was the time they had agreed upon when Yuki had begun her apprenticeship fourteen months ago, and she arrived the way she always arrived — on a bicycle, a gray Surly Cross-Check with panniers that held her tools, her bag lighter than Clara's because she did not yet own the full complement of a working tuner's equipment, carried only the lever (a new one, a Hale number two that Clara had helped her select, lighter than Clara's number four, better suited to Yuki's smaller hands), a set of felt mutes, a chromatic tuner (the Korg that Clara did not use but that Yuki, at this stage of her training, needed as a reference, as training wheels, as a way to verify what her ear told her until her ear could be trusted to tell her without verification), and a notebook in which she recorded observations from each tuning, each lesson, each conversation with Clara, the notebook serving the function that memory would eventually serve, the external record that would, over time, be internalized, absorbed, made into instinct.

She leaned the bicycle against the porch railing and knocked, and Clara opened the door and saw Yuki standing on the porch with her helmet in one hand and her bag over her shoulder, her face flushed from the ride, her dark hair cut short in a way that made her look younger than twenty-eight, though she was twenty-eight, the same age Clara had been when she tuned her first piano alone, the same age that seemed to Clara now impossibly young, impossibly far from the accumulation of experience that separated a beginner from a tuner, though Clara reminded herself that she too had been impossibly young once, had stood on porches with a bag that was too heavy and an ear that was not yet sure of itself.

"Come in," Clara said. "The coffee is made."

They sat at the kitchen table, which was where they always sat before the lesson, drinking coffee from mugs that did not match — Clara's a white ceramic mug with no markings, Yuki's a blue mug with a chip on the rim that Yuki had adopted on her first visit and that had become, through the accretion of small habits that constitutes a relationship, Yuki's mug, the mug Clara set out for her without thinking — and they talked about the week's tunings, which was how every lesson began, with Yuki reporting on the pianos she had tuned during the week, the problems she had encountered, the questions she had not been able to answer.

Yuki had tuned three pianos this week, pianos from the lower end of Clara's client list, the pianos that Clara had assigned to Yuki as her skills developed — a Yamaha studio upright at a daycare center, a Baldwin Hamilton at a private home in Sellwood, a Kawai baby grand at a yoga studio on Alberta that was used for kirtan sessions and that was, as a consequence, always in a state of creative disrepair, the hammers felted with incense residue, the strings filmed with a faint oiliness that Yuki had learned to wipe before tuning.

"The Baldwin was flat all the way through," Yuki said. "Every note, flat. By six cents, maybe seven. Consistent."

"The house is dry," Clara said.

"How do you know."

"If the piano is uniformly flat, the soundboard has lost moisture. The crown drops, the bridge goes down, the strings go slack. Uniform flatness is a humidity problem. If it were flat in some registers and not others, it would be a different problem — a loose pin, a cracked bridge, something mechanical. But uniformly flat is the soundboard, and the soundboard is the humidity."

Yuki wrote this in her notebook. She wrote with a mechanical pencil in handwriting that was small and precise, the handwriting of a musician who had spent years writing fingerings and dynamic markings in scores, handwriting trained by the demands of fitting information into the small spaces between staves, and Clara watched her write and thought about how different Yuki's apprenticeship was from her own, how different it was to learn from someone who was not your father, who was not the voice that had narrated your childhood, who was not the person whose approval you sought with the desperate, bottomless need that children bring to the project of being seen by their parents.

Leonard had taught Clara the way a master craftsman teaches an apprentice in a guild — by demonstration, by correction, by the gradual transfer of responsibility, by the assumption that the apprentice would watch and listen and absorb and that the learning would happen not through explanation but through proximity, through the osmotic transfer of knowledge that occurs when a less experienced person stands next to a more experienced person and watches the more experienced person work. Leonard had rarely explained. He had tuned, and Clara had listened, and when she had made an error he had not said "that is wrong" but had simply tuned the note correctly, and the difference between Clara's tuning and Leonard's tuning had been the lesson, the correction communicated not through words but through sound, through the comparison of two sounds, one wrong and one right, and Clara's ear had learned to hear the difference the way a child learns to hear the difference between a native and a foreign pronunciation — not by rule but by ear, by repetition, by the slow accumulation of correct examples.

Clara taught differently. Clara explained. Clara used words, used metaphors, used the language of acoustics and the language of craft and, when those failed, used her hands, placing Yuki's hand on the lever and guiding the turn, showing her the pressure, the angle, the fraction of a degree that separated a correction from an overcorrection, the physical vocabulary of the tuner's trade. Clara explained because she believed that explanation was owed, that the apprentice deserved to understand not just the how but the why, that the knowledge should be given freely rather than earned through observation, and this belief was, she understood, a reaction to Leonard's method, a correction of it, an improvement or a weakening depending on how you valued the relationship between teacher and student, between the one who knows and the one who is learning to know.

"Let's go to the piano," Clara said.

The Knabe upright stood against the wall of the living room, a 1940 console in walnut, forty-four inches tall, with a tone that was modest and honest, a piano that did not pretend to be better than it was, that produced the sound its size and age entitled it to produce and did not attempt grandeur, did not aspire to the projection of a concert grand or the warmth of a Bösendorfer, was simply a piano, a functional instrument that served its purpose, which was, in Clara's house, the purpose of a tuning reference, a practice surface, a body on which Yuki could learn the techniques that she would later apply to better instruments.

Clara opened the top panel and removed the front board, exposing the strings and the action, and she handed Yuki the lever and said, "Set the temperament."

Yuki took the lever and sat on the bench and struck the fork against her knee — not her own fork, Clara's fork, Leonard's fork, the one fixed point — and touched it to the soundboard and the A bloomed in the small living room, which had the dry acoustics of a room with carpet and curtains and books, the sound absorbed rather than reflected, and Yuki set the lever on the A4 pin and began.

Clara stood behind her and listened.

This was the heart of the lesson — the listening. Clara listened to Yuki tune the way Leonard had listened to Clara tune, with an attention that was total, that tracked every decision Yuki made, every turn of the pin, every struck note, every beat that Yuki heard or failed to hear, and Clara's ear served as the standard against which Yuki's ear was measured, the reference pitch against which the apprentice's pitch was compared, and the comparison was the teaching, the gap between what Yuki heard and what Clara heard was the curriculum.

Yuki set the A and began tuning the intervals of the temperament. She started with F3, tuning it as a fourth below A3, and Clara heard her set the interval slightly narrow — the fourth should have been wide in equal temperament, wide by about one beat per second at this pitch level — and she did not say anything, waited to see if Yuki would catch the error in the cross-checks, the way Clara had caught her own error at Margaret Poole's Story & Clark twenty-eight years ago.

Yuki tuned F3 to C4. A fifth. The fifth sounded correct — approximately one beat per second narrow, which was the equal-tempered fifth at this pitch level. She tuned C4 to E4. A major third. The major third sounded correct — approximately 10.4 beats per second, a rapid flutter that was correct for an equal-tempered major third at this pitch. She checked the cross-interval: F3 to E4. A major seventh. The major seventh beat rapidly, almost a blur, and this was correct for a major seventh, but Yuki paused, her hands still, her head tilted slightly to the left, which was the posture she adopted when she was listening hard, when the ear was working at its limit, and Clara saw the pause and knew that Yuki was hearing something, was sensing an inconsistency, was feeling the wrongness without yet being able to name it.

"Something," Yuki said.

"What."

"The F3. It doesn't — the cross-checks aren't clean."

"What do you hear."

"The major seventh is — I don't know. It's not wrong exactly. It's not clean."

"Check the F3 against A3 again. Listen to the fourth."

Yuki struck F3 and A3 together and listened. The interval rang in the small room, the two notes sounding simultaneously, and Clara heard the beats — approximately 0.8 beats per second, which was slightly slow, which meant the fourth was slightly narrow, which meant the F3 was slightly sharp.

"It's narrow," Yuki said.

"How much."

"I don't — maybe a cent. Maybe two."

"It's about one and a half cents sharp. You set the F3 high. The fourth should be wide — about one beat per second wide, at this pitch. You set it narrow. You heard the beats and you tuned them out — you made the fourth beatless, or nearly so. But a beatless fourth is a pure fourth, and a pure fourth is not an equal-tempered fourth. An equal-tempered fourth is wide. It beats."

Yuki looked at the Korg tuner, which was sitting on the music desk, its screen dark.

"Don't look at it," Clara said.

"I wasn't going to."

"You were going to. Your eyes went to it. That's the reflex I need you to break. The tuner will tell you that the F3 is sharp by one point five cents. The tuner will be right. But the tuner will not tell you what you need to know, which is what the interval sounds like. The tuner measures frequencies. You need to hear relationships."

This was the lesson Clara taught most often, the lesson she considered most important, the lesson that separated a tuner who used an electronic device from a tuner who used the ear, and the distinction was not snobbery — Clara did not disdain electronic tuners, did not regard them as illegitimate, understood that they were useful tools that produced acceptable results — but the distinction was real, was audible, was the difference between a tuning that was correct and a tuning that was musical, between a piano that was in tune and a piano that sang.

An electronic tuner measured the frequency of a single string and compared it to a target. If the string was at the target frequency, the tuner indicated that the string was in tune. This was accurate, as far as it went. But it did not go far enough, because a piano is not a collection of individual strings — a piano is a system of relationships, and the tuning of each string affects the sound of every other string through the overtone series, through the sympathetic vibrations that travel from string to string through the bridge and the soundboard, through the acoustic coupling that makes a piano a single resonating body rather than two hundred and thirty separate vibrating wires, and the electronic tuner could not hear these relationships, could not hear the way a slightly wide octave made the sound open up, could not hear the way a slightly narrow fifth made the thirds more tolerable, could not hear the thousand small adjustments that a skilled ear made to account for the specific inharmonicity of the specific piano in the specific room on the specific day, adjustments that were not deviations from correctness but refinements of it, the difference between a map and a landscape, between a recipe and a meal.

"Listen," Clara said, and she took the lever from Yuki and sat on the bench and adjusted the F3, raising it by one and a half cents, and the fourth — F3 to A3 — began to beat, approximately one beat per second, a gentle pulsing that was the sound of equal temperament, the sound of the compromise, and Clara said, "Hear that. That's correct. That beating is what correct sounds like. Correct is not pure. Correct is not still. Correct is this — this movement, this life. If the interval is still, it's pure, and pure is wrong on a piano. Pure is beautiful and wrong."

Yuki listened. Clara could see her listening, could see the quality of attention in her face, the concentration that was almost a frown, the eyes focused on something that was not visual, on a place inside the head where sound was processed and compared and judged, and Clara remembered this concentration from her own apprenticeship, remembered the effort of training the ear to accept that correct was not pure, that the right answer was not the beautiful answer, that the perfect fifth was not the equal-tempered fifth, that the ear's natural preference for purity had to be overridden, retrained, taught to hear the beating fifth as correct and the pure fifth as wrong, which was the most counterintuitive lesson in all of tuning, the lesson that most beginners resisted, because the ear wanted purity the way the eye wanted symmetry, and equal temperament was the refusal of purity in service of something more useful, more versatile, more democratic.

"Pure is beautiful and wrong," Yuki repeated, and Clara heard in her voice the mixture of understanding and resistance that she had felt herself at this stage, the intellectual acceptance of the principle accompanied by the ear's reluctance to accept it, the dissonance between what you knew and what you heard, which was, Clara thought, a dissonance that never fully resolved, that was present in every tuning she had ever done, a tension between the ear that wanted purity and the craft that required compromise, and this tension was the engine of the tuner's art, the thing that made the work not mechanical but creative, not merely accurate but musical.

"Now do it again," Clara said. "Set the temperament from the A. All twelve notes. By ear. Don't look at the tuner."

Yuki took the lever and began again, and Clara stood behind her and listened, and the small room filled with the sounds of the temperament being set, each interval struck and assessed and adjusted, each beat rate counted and compared to the standard in Clara's ear, and Clara corrected when correction was needed — "the third is wide, bring the E down" — and praised when praise was earned — "that fifth is good, that's exactly right" — and the lesson had the rhythm of all tuning lessons, the patient alternation of error and correction, the slow approach toward accuracy, the ear learning by repetition what it could not learn by explanation.

After forty minutes Yuki had set the temperament and Clara checked it, playing through the intervals, the fifths and fourths and thirds and sixths, and the temperament was acceptable — not perfect, not as clean as Clara would have set it, but acceptable, within the tolerance that a client would accept, within the range where the intervals were correctly tempered even if the specific beat rates were not precisely what Clara's ear would have demanded — and Clara said, "Good. Now tune the octaves up."

Yuki began tuning octaves upward from the temperament, and as she moved into the treble, above C6, above C7, into the territory where the strings were short and stiff and the inharmonicity was extreme, Clara began to listen not just to the piano but to Yuki's listening, began to hear not just the notes but Yuki's response to the notes, the pauses that indicated uncertainty, the quick corrections that indicated confidence, and she noticed something that she had noticed before but that had become more pronounced in recent weeks: Yuki's ear was good in the upper treble. Yuki heard the high frequencies clearly, heard the beats between the upper partials with a resolution that was, Clara recognized, better than Clara's current resolution, sharper, cleaner, the ear of a twenty-eight-year-old whose cochlea was intact, whose hair cells were all present, whose upper limit of hearing was still at or near the biological maximum.

Clara did not think about this. She heard it, noted it, set it aside.

Yuki finished the octaves and tuned the unisons and the piano was in tune, or as in tune as a student's tuning could make it, and she set the lever on the music desk and flexed her left wrist, the injured wrist, the wrist that had ended her performing career, and the flexion was unconscious, habitual, a gesture that Clara had seen hundreds of times, the body remembering the injury even when the mind was occupied with other things.

The wrist had been injured three years ago, during Yuki's final year at the Oberlin Conservatory, where she had been studying piano performance with the intention of becoming a concert pianist. She had been practicing Liszt's Transcendental Etude No. 10 in F minor, a piece that demanded extreme extensions of the left hand, rapid octave passages that stretched the tendons of the wrist to their limits, and she had practiced it for six hours a day for three weeks, preparing for a competition, and on the twenty-second day she had felt a sharp pain in her left wrist, a pain that began at the base of the thumb and radiated up the forearm, and she had stopped practicing and gone to the campus health center and been diagnosed with de Quervain's tenosynovitis, inflammation of the tendons that control the thumb, and the doctor had said rest, and she had rested for two weeks and the pain had subsided, and she had returned to practice and the pain had returned, immediately, within the first hour, and she had stopped and rested again and returned and the pain had returned again, and this cycle — practice, pain, rest, return, pain — had repeated four times over the course of three months, and by the end of the three months the orthopedic specialist she had been referred to had said that the tendons were chronically inflamed, that the sheath through which they traveled was thickened and scarred, that she could play at a recreational level but could not practice at the level a concert career required, that the career she had spent seventeen years preparing for was over.

Yuki had told Clara this story on the day she came to ask about apprenticing. She had sat at Clara's kitchen table with a cup of coffee in the blue mug and had told the story without self-pity and without drama, had told it the way you tell the story of an event that you have processed, that you have moved through, that you have accepted not because acceptance is easy but because the alternative — refusing to accept — is a form of madness, a refusal to live in the world as it is, and Clara had listened and had recognized in Yuki's telling the same quality that Leonard had brought to his announcement that he could no longer hear the seventh partial of C8, the quality of a person stating a fact and asking what comes next.

What came next was tuning. Yuki had researched apprenticeships, had found Clara's name through the Piano Technicians Guild directory, had called and asked whether Clara took apprentices, and Clara had said no, she did not take apprentices, she had never taken an apprentice, she worked alone and preferred it that way, and Yuki had said she understood and asked whether she could observe, just once, just one tuning, and Clara had said yes, one tuning, and had taken Yuki along to a tuning at a private home in Irvington, and Yuki had sat in a chair and watched Clara tune a Yamaha C3 grand for two hours and had not spoken, had not asked questions, had simply watched and listened with the attention of a musician, the attention of someone who understood that listening was not passive but active, that hearing was a form of doing, and when Clara had finished and packed her tools and walked to the car, Yuki had followed her and said, "I heard the fourth partial of the A3 beating against the fundamental of E5 at 7.4 beats per second," and Clara had looked at her and known, immediately and without reservation, that Yuki had the ear.

Clara had accepted her as an apprentice the next day.

Now, fourteen months later, Yuki was tuning three pianos a week on her own and spending Wednesday mornings at Clara's house, working on the Knabe, refining her ear, and Clara was teaching her everything Leonard had taught Clara and some things Leonard had not taught because Leonard had not needed to teach them because Clara had absorbed them by proximity, by osmosis, by the years of standing behind her father and hearing the right way and the wrong way and learning to distinguish between them, and Clara was translating this absorbed knowledge into explicit instruction, was finding words for things that Leonard had communicated through demonstration, was building a curriculum from a tradition, which was, she thought, a form of translation, a conversion of one language into another, the language of doing into the language of telling.

"How's the wrist," Clara said, as Yuki packed her tools.

"Fine. A little stiff after long tunings. The Kawai at the yoga studio took two hours and the wrist was sore after."

"You need to use less pressure on the lever. You're gripping too hard. The lever should move the pin, not your hand. Your hand holds the lever. The lever does the work."

"I know. I forget."

"Forgetting is a form of not knowing."

Yuki smiled. "That sounds like something your father would have said."

"It is something my father said."

They sat for a moment in the quiet of the living room, the Knabe in tune beside them, the rain tapping on the windows, and Clara looked at Yuki and thought about the conversation with Mrs. Ashford, about Mrs. Ashford's insistence that Yuki was a musician, not a technician, that Yuki should play, should compete, should not abandon the piano as a performing instrument just because her wrist would not allow the Liszt, and Clara understood Mrs. Ashford's position and respected it and also disagreed with it, because tuning was not a consolation prize, was not the thing you did when you could not do the thing you wanted, was not less than performing but different from performing, was, in Clara's judgment, the more essential work, the work that made all the other work possible, the invisible labor on which the visible art depended, and if Yuki could learn to hear this, could learn to feel the satisfaction that Clara felt when a piano came into tune under her hands, then Yuki would not need to play in competitions, would not need the audience and the applause and the reviews, would have instead the quiet satisfaction of the tuning itself, the satisfaction that was, for Clara, sufficient.

But Clara also knew that this was her satisfaction, not Yuki's, and that what was sufficient for Clara might not be sufficient for Yuki, and that the question of whether tuning was enough — enough for a life, enough for a person who had dreamed of Carnegie Hall and had ended up in living rooms with felt mutes and a lever — was a question that Yuki had to answer for herself, and the answer might take years, might not arrive until Yuki had tuned her thousandth piano, might not arrive at all.

"Mrs. Ashford wants you to come play her Bösendorfer," Clara said.

Yuki's face changed. The change was slight — a tightening around the eyes, a small compression of the mouth — but Clara saw it, read it, understood it as the response of a pianist to the name of a great piano, the involuntary recognition, the hunger that a wrist injury could not kill because the hunger was not in the wrist but in the ear, in the fingers, in the part of the brain that dreamed in music.

"I'm not — I don't play anymore. Not really."

"She didn't ask you to perform. She asked you to come play."

"There's a difference."

"Yes. She knows the difference."

Yuki was quiet for a moment, looking at the Knabe, at the keys that were covered by the fallboard, at the wood that hid the instrument that she had just spent forty minutes tuning, and Clara could see her thinking about the Bösendorfer, about the nine feet six inches of Austrian engineering and Alpine spruce, about the ivory keys that Mrs. Ashford's fingers had polished for thirty-seven years, about the sound that the Bösendorfer made, which Yuki had heard once, during a tuning that Clara had brought her along to observe, and which had produced in Yuki a response that Clara had recognized because it was the same response Clara had had the first time she heard the Bösendorfer, which was not admiration or envy but something closer to love, the instantaneous recognition that this particular piano produced a sound that no other piano produced, that this was not just a piano but the piano, the Platonic form of the instrument, the sound that all other pianos were trying to produce.

"I'll think about it," Yuki said.

"Think about it."

Yuki put on her jacket and her helmet and gathered her bag and went to the door, and at the door she paused and said, "Clara, can I ask you something."

"Yes."

"When you tune the upper treble — the top octave, above C7 — do you use the tuner or your ear."

The question was casual, was technical, was the kind of question that an apprentice asks a teacher in the normal course of learning, and Clara answered it casually, technically, the way a teacher answers a student's question, but inside, behind the answer, behind the words, something moved, something shifted, the way the ground shifts before an earthquake, imperceptibly, a movement you feel only in retrospect.

"I use my ear," Clara said. "Always. The tuner can't hear what I hear in the upper treble. It measures frequencies. I hear the sound."

"Even above — what, 4,000 hertz? The top octave is above 4,000."

"The fundamental is above 4,000. But you're not listening to the fundamental in the top octave. You're listening to the relationship between the note and the note below. The octave. The quality of the octave. Whether it's clean or dirty, narrow or wide. The tuner can tell you whether the fundamental is at the right frequency, but it can't tell you whether the octave sounds right, because sounding right depends on the inharmonicity of both strings, on the partials, on the interaction between the overtone series of the two notes, and that's — that's what the ear does. That's the ear's job."

"But if the fundamentals are above 4,000 hertz, and the partials are even higher — you're listening to 8,000, 10,000, even higher. Can you hear that clearly."

"I can hear it," Clara said.

The words came out steady, came out with the confidence of a tuner who had been hearing those frequencies for twenty-eight years, and the confidence was real, was not false, was based on twenty-eight years of evidence that her ear could hear what it needed to hear, and the evidence was true, had been true for twenty-eight years, and the question was whether it was still true, whether the evidence of the past was evidence of the present, and this question Clara could not answer, not standing in her doorway on a Wednesday morning, not to her apprentice whose trust in Clara's ear was the foundation of her apprenticeship.

"Good," Yuki said. "I just — I can hear it, but I wasn't sure if — I just wanted to know. Whether you could still — whether you still use your ear up there."

"I use my ear everywhere," Clara said. "That's what we do. That's the whole thing."

Yuki nodded and went out into the rain, and Clara watched her unlock the bicycle and swing her bag into the pannier and pedal away down Yamhill, and Clara stood in the doorway and felt the rain on her face and thought about the question Yuki had asked, the question that was technical on the surface and something else underneath, and she wondered whether Yuki had noticed something, whether Yuki's twenty-eight-year-old ear had heard something in Clara's upper treble tunings that Clara's fifty-two-year-old ear had not heard, whether the apprentice had detected in the master's work a flaw that the master could not detect because the flaw was in the master's instrument of detection.

She closed the door.

She went to the Knabe and opened the fallboard and sat on the bench and played a scale in C major, four octaves, from C2 to C6, and the piano was in tune — Yuki had tuned it and Clara had checked it and it was correct, within tolerance, the intervals tempered, the octaves clean, the unisons alive — and Clara continued up the keyboard, past C6, past C7, into the top octave, C7 to C8, and she played each note slowly, individually, listening not for the tuning but for the tone, for the quality of the sound, for the overtones that rose above the fundamental like harmonics above a melody, and she heard them, heard the partials, heard the brightness and the thinness and the almost-metallic quality of the highest notes, the notes that were more percussion than pitch, and she heard them clearly, or believed she heard them clearly, or told herself she heard them clearly, and she could not determine which of these was true because the determination required a standard, required a reference, required a comparison between what she heard now and what she had heard before, and the comparison was impossible because the before existed only in memory, and memory was not a tuning fork, was not a fixed reference, was not reliable the way steel was reliable, was instead a thing that changed, that drifted, that adjusted itself to accommodate the present, the way a piano adjusts to the humidity, the soundboard swelling and contracting, the pitch rising and falling, the instrument adapting to conditions that the instrument cannot control.

She closed the fallboard and went to the kitchen and took the tuning fork from the table and struck it against her knee.

A440.

She held it to her ear, close, the tines vibrating inches from the opening of the ear canal, and the tone was there, full and clear, the fundamental at 440 hertz and the first overtone at 880 and the second at 1,320 and the third at 1,760, each partial diminishing in amplitude but present, audible, distinct, and she listened for the highest partials she could hear, the fourth at 2,200, the fifth at 2,640, the sixth at 3,080, the seventh at 3,520, the eighth at 3,960, the ninth at 4,400, the tenth at 4,840, and somewhere above the tenth the partials merged with the background noise of the kitchen, became inaudible, not because they were absent from the fork's vibration but because they were below the threshold of Clara's hearing at those frequencies, below the level at which the hair cells in her cochlea could transduce them into signals the brain could interpret as sound, and Clara tried to locate the boundary, tried to find the frequency above which she could no longer hear the fork, and she could not find it precisely, could not draw a sharp line, because the boundary was not sharp but gradual, a fade rather than a cutoff, a dimming rather than a darkness, and this gradualness was what made the loss — if it was loss — so difficult to assess, so difficult to distinguish from the normal limitations of a tuning fork struck in a kitchen with a refrigerator running and rain on the roof and a furnace cycling.

She set the fork on the table.

Thursday. Tomorrow.

She spent the rest of Wednesday doing administrative work — updating her schedule, sending invoices, ordering replacement felt mutes from a supplier in Cincinnati, returning a call from a potential new client, a woman in Lake Oswego who had recently purchased a rebuilt Steinway A and wanted a tuner who did not use an electronic device, who tuned by ear, who could hear the piano rather than just measure it, and Clara had said yes, she tuned by ear, and had made an appointment for the following week, and as she said the words — "I tune by ear" — she heard them differently than she had heard them every other time she had said them, heard them not as a statement of practice but as a claim, a promise, a declaration of capability that she was no longer certain she could keep.

She ate dinner alone, as she always ate dinner, pasta with olive oil and garlic and whatever vegetable was in the refrigerator, tonight broccoli, and she ate at the kitchen table with the tuning fork in front of her like a utensil, like a piece of silverware, the fork that Leonard had carried from Leningrad in 1971, the fork that had set the reference pitch for every piano Leonard had ever tuned and every piano Clara had ever tuned, the fork that was the single fixed point, the one true thing, and she looked at it while she ate and thought about what it would mean if her ear could no longer hear what the fork asked it to hear.

The fork would still vibrate at 440 hertz. That was what a tuning fork was — a thing that did not change. The fork was not aging. The fork was not losing its upper partials. The fork was not subject to the biological processes that were, perhaps, degrading Clara's cochlea. The fork would vibrate at 440 hertz on the day Clara died, the same as on the day Leonard died, the same as on the day the anonymous tuner at the Leningrad Conservatory had given it to Leonard in 1971, and this permanence, this immunity to time, was both the fork's virtue and its reproach, because the fork could not lose what Clara was losing, could not understand what it meant to lose it, could only continue to vibrate at the frequency it had always vibrated at, oblivious and exact and perfectly, permanently in tune.

She washed the dishes. She dried them and put them away. She went to the living room and sat at the Knabe and played — not tuning, not practicing, but playing, the Chopin Nocturne in C-sharp minor, the posthumous one, the one that is less famous than the E-flat major but that Clara preferred because it was darker, more inward, more like the sound of someone thinking than the sound of someone performing, and she played it slowly, the way Mrs. Ashford played the E-flat, slowly because slowness was a form of attention, and her fingers moved on the keys with the dexterity of a person who had been playing the piano since she was five and tuning since she was twenty-one and who had never stopped either, and the music filled the small house and went out through the walls and the windows into the rain, and the rain absorbed it the way rain absorbs everything, without comment, without judgment, the sound disappearing into the water and the air and the night.

She stopped playing. She closed the fallboard. She went to the kitchen and struck the fork one more time.

A440. Clear. True. Present.

She went to bed. Tomorrow was Thursday. Tomorrow was the audiologist. Tomorrow was the measurement. Tomorrow was the graph that would show what Clara could hear and what she could not, the line between the frequencies that were still hers and the frequencies that had left her, and Clara lay in the dark and listened to the silence and tried to hear, in the silence, the highest frequency she could perceive, tried to generate internally the test that tomorrow's audiologist would administer externally, tried to hear the edge of her own hearing, the place where sound became not-sound, where hearing became not-hearing, where Clara became not-Clara but someone else, someone with a different ear, a different capacity, a different relationship to the pianos that had been the organizing principle of her life for twenty-eight years.

She could not find the edge. The edge was not something you could hear, because it was, by definition, the place where hearing ended.

She slept.
