OK, after three days in bed (incidentally missing a rather well-paid concert

: ) I finally got back here.
Ds was very attuned to music from birth, too. On one of the rare occasions after he was first born that I was practicing, my Mom came walking down the corridor with him but then decided she'd better not disturb me. He burst into tears, so she brought him in and he watched me for about 10 minutes. I think he was about 3 weeks old at the time. She would sit with him in the back of the car and say, "You know, he's really listening to the radio." I remember him at about three months, too, being glued to an old black and white movie of a David Oistrakh recital. By 4 he was watching Beethoven 9 - on one occasion leaping out of bed and watching the whole thing before breakfast.
Right from the start his hands looked...capable. Seems like a strange thing to say about a tiny baby, but they looked like they were hotwired to his brain, somehow. At 9 months he was turning the dimmer switches on the lights, and I remember thinking, if he really does have musical feeling, this could be interesting. We did Music Together classes and he was much more into rhythm than pitch. He loved to dance and by the time he was two he was really responding in a lot of detail to the emotional content of the music - he would change his dancing very deliberately as the music changed, he would "get" the funny parts and so on.
When he was three I brought up the junky keyboard from my violin studio up to the living room for the summer. I realized that in his noodling he always came back to C, so I knew that he was getting the tonality of the instrument. I told him that was C, this was D and so on, and a few days later he started saying, "The fridge is playing E...the phone rings F" and I realized he had perfect pitch. Then I started singing the "resting tone" (as they called it in MT) while the radio was on, and pretty soon he was telling me the key of every piece on the radio. It turned out he also knew the keys of MT songs from two years ago - he had them all stored in there at pitch.
So he started piano just before he was four with a wonderful (Suzuki) teacher, and it was challenging, because he was (and still is) very, very wiggly and self-directed, but every time I backed off a bit he seemed to want more. The funny thing was, every time he sat down to perform, he looked like an adult - completely focused. Right from the start he was transposing his pieces into other keys for fun, and just playing in a completely different way from the other kids.
His teacher started giving him lots of performing opportunities, at nursing homes and so on, and he just loves to perform. Then this spring she had an older kid drop out of the concerto event and she put him in. The piece (Haydn concerto in C, first movement) was at least a year or two ahead of where he was technically, but he learnt in in five weeks straight and had the time of his life (although he was nervous the night before - the only time I've ever seen him nervous - as it turned out, he was afraid they would pick a faster tempo, so once I explained that HE would set the tempo he was OK).
I'm probably sounding braggy (but hey, you asked!), but he really does have that special "something" when he plays. He wants to play violin too and we rented one for a while but hardly touched it - it's hard to fit that in with everything else we do. I'm hoping once we get a bit more organized and he matures and settles down a bit (his energy is still a bit out of control) we'll be able to pick it up again. I think the piano is working great for him though - he loves to improvise, and he's learned a great deal about theory from his piano lessons. He seems to have all of musical theory built into his brain, and you just have to give him the labels - like with the perfect pitch, it was as if he'd known it all along but just didn't know the notes had names. I think music is really his first language, actually - he's not bad verbally but music is 100% natural for him. It's a real joy to work with him - although I'm musical, I didn't necessarily expect that he would be too, or have such a complete package. It's a great blessing!
