An old piano tuner in Piacenza works out, on the back of an invoice, that the city cannot feed a second tuner, and so cannot feed his apprentice. Then he checks his own appointment book and finds which factor he had never checked.

The Schimmel on the fourth floor in Via Taverna had gone sharp, as they all do in September.
Aurelio Groppi struck the A above middle C, held the fork against the cheek of the case, and listened. The two sounds rubbed against each other. Wah, wah, wah, wah. Four in a second, a little more. So the piano stood at 444, not 440. He did not need to test the rest of the middle. A wet summer in the Po valley pushes up the crown of the soundboard, the board pushes up the bridges, and the strings go tight. The middle rises most. The bass rises less, because the bass strings are heavy and do not care. The top is always its own country.
"Four," said Ines, from the doorway.
"Four and a bit."
"How do you know the bit?"
"Because four is too round. Nature does not give you round numbers. If you hear four, it is four and a bit, or three and a bit, and you must decide which." He put the fork back in his waistcoat. "Here it is four and a bit. Bring me the strip."
She brought the felt strip from the bag and he wove it between the strings of the middle two octaves, so that each note sounded on one string only. His fingers knew the work. His knees did not know it any more. He sat on Signora Bosi's piano stool, which was too low, and his right knee said something about that, and he told it to be quiet.
Ines had been carrying the bag for twenty-eight days. He had counted. She was thirty-four, she had studied mechanical engineering in Milan for two years and then cello at the Nicolini for four, and she played in the pit at the Municipale when they needed a second cello, which was not often. She had come to his workshop at the end of August with a letter she did not give him, because she decided in the doorway that a letter was stupid, and she said instead: "Teach me, or tell me why not."
He had said: "Come for a month. At the end of the month I will tell you why not."
The month ended on Wednesday.
He set the A first, to 440, because the Signora's daughter played with a violinist from Parma who complained. He tuned the A an octave below from it. Then he put the lever on the pin of the E above that one, pulled it down a hair and brought it up slowly, and played the two together. A fifth.
"Count," he said.
Ines had a cheap watch with a second hand. She did not look at it much any more; she had learned to feel a second in her arm, like a bow stroke. The fifth rolled, slow, a long lazy wave inside the sound.
"Seven," she said after a while. "Seven and a half. In ten seconds."
"Good. That is a correct fifth. Narrow, not pure. If it is pure, it is wrong."
She knew this already. He told her again because the telling was part of the tuning, like the fork. The third harmonic of the A and the second harmonic of the E want to sit on the same frequency, and in the tempered scale they must not; they must miss by three quarters of a cycle every second, so that twelve fifths close into seven octaves and the circle does not leak. Every tuner in the world has this fact in his arm. Most of them could not write it down. Aurelio could write it down, and it did not help him tune any better, but it helped him not to lie to himself.
He set the D. A fourth this time, wide, about one beat a second. Then the thirds, which are ugly in the tempered scale and must be ugly in the right amount: F to A, seven a second, a fast shimmer; A to C sharp, faster, nearly nine. Each third a little faster than the one below. If they go up like a staircase, the temperament is good. If one step is flat, a note is wrong, and you find which.
"Now you," he said, and stood, because standing was easier than sitting now.
She took the stool. She put the lever on the pin of the B flat. Her hand was too far out on the handle, as always, and he did not correct it, because she would find out herself in about two hundred pianos that the wrist gets tired, and a thing you find out yourself stays.
Afterwards, in the car, while she drove because he did not drive in the centre any more, he took an invoice book out of his bag and turned to the back of the last sheet.
"You want to know why not," he said. "Good. I will show you why not. It is not a question of opinion."
She pulled out of Via Taverna and waited for a bus. "All right."
"How many people in Piacenza?"
"A hundred thousand."
"A hundred thousand. How many in a family?"
"Two. Two and a bit."
He smiled; she had been listening. "Two and a bit. So forty-five thousand households. How many have a piano?"
She thought about the flats they had been in. The Signora Bosi, the notary on Corso Vittorio Emanuele, the family of engineers in the new houses out past the Farnesiana. "Not many. In Italy, not many. One in twenty?"
"Too many. One in thirty. Say fifteen hundred pianos in houses. Most of them are furniture. They hold up photographs of the grandchildren. How many are tuned in a year?"
"A third."
"A third. Five hundred tunings. Now add the Conservatorio, the schools, the churches that still have a piano and not an electric thing, the Municipale, the two halls. The Conservatorio is the big one. Their pianos are played eight hours a day by children who hit them. Four hundred tunings, perhaps."
"Nine hundred," said Ines.
"Nine hundred a year. Now the supply. One tuner, working honestly. Three pianos a day, because between them he must drive and park, and in the centre parking is itself a profession. Two hundred and twenty days." He wrote it: three times two hundred and twenty. "Six hundred and sixty. So." He divided. "Nine hundred over six hundred and sixty. One point four."
The bus pulled away. She did not move the car.
"One point four tuners," he said. "Piacenza can feed one tuner and four tenths of another. There is also Mazzocchi from Cremona, who comes when I am busy, and the young one from Parma who does the Conservatorio's uprights for less than I do and badly. So the four tenths is already eaten. There is no second tuner in this city. There is one, and a bit, and the bit is taken."
Someone behind them sounded a horn. Ines put the car in gear.
"That is why not," Aurelio said. "Not because you are a woman, not because you are a cellist, which is worse. You have a good ear and you count honestly. It is arithmetic. I did not want to tell you in words. In words it sounds like I am being unkind. In numbers it is just what is true."
She drove to the workshop without speaking. At the door she said, "The number is wrong."
"Which factor?"
"I don't know yet."
"Then it is not wrong. It is only unwelcome." He got out of the car. His knee took the weight badly and he held the roof for a moment. "Tomorrow the Municipale, eight o'clock. The Steinway, for Thursday's recital. Bring the long mutes."
The Municipale in the morning was cold even in September. The stage lights were off except one work lamp, and the Steinway stood under it with its lid off like a patient on a table. The pianist wanted 442. Italian orchestras had crept up from 440 in his lifetime, and the soloists followed, because a high piano is a bright piano and bright is exciting in a large hall. Aurelio did not approve. Nobody asked him to approve.
Eighty-eight notes, two hundred and forty-odd strings, each one pulled to about seventy or eighty kilograms. Call it eighteen tonnes on the iron frame, sitting there quietly, waiting for the humidity to change. He liked to tell customers this when they put a vase of flowers on the lid. Eighteen tonnes, Signora, and you give it water.
He set the temperament himself. His ear was good in the morning. He did not like to admit how good it was in the morning compared with the afternoon; after three o'clock the fifths began to sound alike to him, and he had learned not to set temperaments after three.
Then the unisons, the octaves, outward from the middle. The high treble he did kneeling, because on a concert grand you get your head closer to the strings that way and the short strings are shy. He knelt. The right knee went down onto the boards and something inside it moved that should not have moved, and he stayed down for a while with his forehead near the rim of the case, breathing, and pretended to be listening to the top C.
Ines said nothing. When he got up, holding the case, she was looking at the stage floor and not at him.
"The top two octaves," he said. "You do them. Stretch them a little. The strings of the treble are stiff, the overtones come out sharp, so the octaves must be wide or they sound flat to the hall. Not too much. Listen to the octave, then listen to the double octave. When both are sweet, stop."
She knelt where he had knelt. It took her fifty minutes. It should have taken twenty-five. He sat in the front row of the stalls with his leg out along the seat and did not interrupt her once, and at the end he went up and played a scale in the top octave, and a chord, and the C at the very top against the C below, and he said: "Good."
It was good. It was not as good as his. It would be, in about two hundred pianos.
That night he sat at the workbench in the shop with the appointment book, because the number was wrong and he did not know which factor either, and he did not like not knowing.
The book was a big blue diary from the stationer in Via Roma. He had kept one every year since 1978. He opened September and counted.
Tunings done in September, so far, twenty-nine days: thirty-eight. He counted again. Thirty-eight. Working days in September: twenty-one. Thirty-eight over twenty-one. One point eight a day.
He sat back.
One point eight. Not three. He had written three in the car, on the back of the invoice, without thinking, because three had been true. Three had been true in 2010. In 1985 it had been five. He had been using the old factor for the one term in the equation he knew best, which is always the term you do not check.
He turned to the back of the diary, where he wrote down, in pencil, the calls he could not take. He did not know why he wrote them down. A habit from the years when he was building the business and every refused call was money on the floor. The list for September went over a page. Some of them he had passed to Mazzocchi. Some he had simply told: November, Signora, the first week of November, and some of them had said yes and some of them had said they would call the man from Parma.
He counted the refusals. Twenty-six. In one month.
So. Demand in a month: thirty-eight done, twenty-six refused, sixty-four. Some refused ones would call again and be counted twice; some never called at all because they knew he was busy. Those two errors pulled in opposite directions. Leave them. Sixty-four a month, twelve months, but not twelve: August is dead, and the Christmas weeks. Say ten and a half. Six hundred and seventy. Plus what Mazzocchi and the boy from Parma were already doing in Piacenza, which he could only guess. A hundred and fifty, two hundred. Say eight hundred and fifty altogether.
Nine hundred, he had said in the car. Eight hundred and fifty from the diary. Within ten per cent. The demand was right. The demand had never been the problem.
The problem was the denominator. He wrote it on the back of the invoice sheet, under the first calculation.
One point eight a day. Say two. Two hundred days now, not two hundred and twenty, because the knee, because the doctor in March. Four hundred.
Eight hundred and fifty over four hundred.
Two point one.
He looked at it for some time. Then, because it was his rule, he looked at it again from the other end, to see whether he wanted it to be true. He was seventy-one. The number said that he was already, this year, less than half of what the city needed, and that the other half was being done in Parma and Cremona by people who did not know which Conservatorio pianos had cracked pinblocks, and which church had mice. It said that in five years, when he was nought point nought tuners, the city would need two and would have none that lived in it.
The number was not wrong. His estimate of himself was wrong. He had kept himself at three a day on paper the way people keep a photograph of themselves at forty on the piano.
He tore the sheet off the invoice book, folded it once, and put it in his waistcoat pocket with the fork.
On Wednesday they did the Signora Bosi's Schimmel again, because the violinist from Parma had complained again, and this time the Signora was right: the D above middle C had slipped. A loose pin. It happens in old pinblocks when the weather turns; the wood breathes out and lets go.
"You," said Aurelio.
Ines looked at him. It was the thirtieth. She knew what day it was; he could see she had been carrying it in her face since the car.
"Set the A," he said. "Then the E below. Seven beats in ten seconds, seven and a half. Then tell me if the D can hold, or if we must drive the pin."
She set the A. She put the lever on the E. Her hand was too far out on the handle, and this time he reached over and moved it in, two fingers' width, toward the pin.
"There," he said. "Or the wrist goes, in about two hundred pianos. After that you will need your wrist for another ten thousand."
She did not answer. She played the fifth and counted, and he counted with her, not aloud. The slow wave rolled in the middle of the sound. Four, five, six. He took the folded sheet from his pocket and put it on the music desk in front of her, where the Signora's daughter kept her Czerny, and left it there, and went to the window to rest his knee.
Seven. Seven and a half.
