Every morning during every third week of school, I spend half an hour listening to toots and honks, squawks and whistles, in various states of harmony and dissonance as band members willing to come in before school practice their pieces. I peek into the room and see at least one or two students who, in my class, are less than focused. Here, they’re all focus, all attention, counting out measures as they wait for their entrance, glancing here and there in anticipation of the trumpets’ entry or the flutes’ flourish.
