"You look troubled," Ms. Johnson said. "Did somebody say something to you?"
"I heard something at soundcheck," Zara answered. She explained the strained note, the sudden perfect replacement, and how the recorded phrase had continued through Chase's cough. "I don't think he's singing that high part," she finished. "I think somebody else is."
Ms. Johnson was quiet for a long moment. Her expression was not disbelief, exactly, but the careful face adults wore when they realized a child was about to ask a question with consequences. "You may be right about the recording," she said. "But don't accuse anybody publicly on what you heard once. A performance can have complicated arrangements, and it's important to know exactly what someone claimed before you say they lied."
"He says it in interviews," Zara replied. "He says nobody else can sing it."
"Then perhaps he is exaggerating. Plenty of famous people do that." Ms. Johnson knelt so their eyes were level. "For tonight, you are here to sing your part with the school, and I am responsible for keeping you safe. If something else needs to be said, we can decide together afterward."
Zara nodded, though the answer did not settle the question. It left the discovery suspended between her ears and her sense of fairness, two parts of herself that had always agreed before. She wanted to enjoy the evening and did not want to be the child who ruined it for everybody. She also remembered her mother's warning that a person should never pretend to believe something merely because the person saying it was important.
Before the doors opened, Zara caught sight of a glossy program left on a backstage chair. She recognized the names Chase Hendricks and Marcus Webb, the veteran producer credited on the famous recording, along with a long list of musicians and technicians. Near the bottom, printed in small type, were the words Additional Vocals: Sophia Mitchell. Zara did not know the singer, but she read the name twice and remembered it because she liked the sound of it.
In the auditorium, guests began filing in. Ushers guided women in glittering dresses and men in dark suits toward their seats, while camera operators tested angles designed to make every applause break appear enormous. Some guests were celebrities and some were business executives whose companies had purchased tables for thousands of dollars. Zara watched them from the wings and wondered whether any of them had ever attended a concert in a school gym with a piano missing three keys.
Chase greeted donors with the enthusiasm of someone who knew exactly where each camera was positioned. He put his arm around a principal from another school, promised a smiling child a private backstage visit, and praised music education in a tone rich with practiced emotion. None of those moments was necessarily false. But Zara began to suspect he understood the value of children as scenery more clearly than he understood the value of what they actually wanted to learn.
