I took my son to a Music and Me class when he was 3 or 4. It was pretty good. Played around on the piano. Learned some basic music theory. Rhythm, tempo, Middle C, whole notes, quarter notes, half notes, rest. Got a CD of the songs they play to listen to at home.
I'm signing him back up for group piano lessons now at age 8, this fall.
I don't know how it compares to Jordan Kitt's, though.
