He watched as the barbershop quartet, resplendent in striped blazers, butchered the complicated harmonies of his jazz piece.

He imagined the reaction of his music teacher, a stern woman who had always criticized his experimental style. He pulled out his phone, ready to record the moment, his internal glee bubbling like champagne.
