This video is not surprising to me.
My son has Aspergers (as do I) in the high functioning scale, very smart kid.
He was
very young (1) on my lap hitting the snare and floor tom (together) all the time. I crossed his hand over to the hats, ch ch ch ch ch...and it was all over. After that he could just do it.
He would wake us up singing drum beats in his crib.
He was just 2 when he got his first JR. kit.
He would spend a half hour playing with sticks on a tree. He played a hole through the plaster on one small wall in our kitchen. We just let him because we were working on stuff anyway. We just fixed that last
At 3-31/2 he would tell me which Rush DVD to put in (the Black one, or the Red one) and then, he'd go down stairs...dun dun, dun dun, dun dun.... he could do that dun chi chi, dun chi chi rhythm
and the snare hits (WTF?! he's freaking 3!)...then he would spin around and play like he was on the electronic kit... he would kinda freak us out shaking our heads.
The only issue he has with drums now is the noise sensitivity (started about age 6), so he doesn't play his electronic kit he got last year as much, but it seems to be going away lately. He hadn't touched the acoustic kit in ages because of the volume, even with good hearing protection.
But, it seems to be lessening (he's 10 now), so we hope he gets back into playing.
They found that the actual motions you make when you play drums are soothing, and when I heard that, I though, "no wonder I like just grooving hard so much".
