[Ben is less experienced with the mechanics of playing than one might think to listen to him, in turn, play; but his ear is very sharp, and he's listened to several classical pieces repeatedly to commit them to memory. To learn to replicate them by sound and, then, to match the sound to the sheet music that he has been slower to pick up.

He notes the mistakes. He notes, also, the extremely high level of competence.]

How long have you been playing?
