Nice. We're listening. My kid asks, "Who is this?" I said, "One of my friends on Metachat... this is his son's teacher." Husband says, "Too bad it's not his son." :-) Is this your son's piano teacher or schoolteacher? I assume it's his piano teacher.
It's the teacher of his Music Theory 101 course at the Hunter College "College Now" program, where NYC high school kids take college courses for free at the City University of New York.
