love reading your experiences...
well, a friend gave my 3 yo son a junk trumpet (that works but needs some help), and Nick is able to make a good clear note with the thing and practiced for about 30 mins straight.
still at a loss- he's so young, he can follow directions but has some psychomotor overexcitability. do I take the plunge and try some lessons, either trumpet or violin? hmmm...wish he wanted to play piano, we've got one, he can do chopsticks independently, but refuses lessons. He's got a drumkit and plays in tandem with my DH who is a gifted drummer, so no formal training needed there...will think some more..
