Crossed wires, huh? Sounds like you should be playing the accordion. I think crossed wires is a prerequisite for that.

I remember that when I was a child, I used to be really attracted to the idea of playing the accordion. But I never had a chance to play one (other than a cheap little toy accordion that was not the same thing at all) until about a year and a half ago. Maybe if you show your son a lot of different instruments you could see if he is particularly attracted to any of them.

In my own son's case, he took lessons on the violin, the hammered dulcimer, and drums. I think he could be good on any of those instruments but his first love is filmmaking. He prefers to devote pretty much all of his available time to making films and is not willing to take time away from that in order to play music. That's ok, though. He makes good movies ;-)
