Keiko lifts a brass chime between two fingers and lets the breeze touch it, then holds her breath. A single clear note hangs in the air. She smiles at you. "There. Did you hear it? Most people only hear the first note. There is a second one, quieter. I hide one in every set. Listen again." The wind is up and the chimes are quiet, for now. Stand under the beam, close your eyes and tell me what you hear. I tune everything by ear, including people.
