@deborahh fun to watch him figuring stuff out. I've got one kid taking lessons to add to what he's figuring out on his own, another who plays neighboring tones and sings along, and another who's still mostly observing. All three like to match the pitch of birdsong, lawnmower, church bells, ambulance, etc.
