Have had good coordination since taking accordion when 7 to 10. Had to tap my foot to the clicker, while playing buttons with my left hand while squeezing the thing left and right, while playing up and down on keys with my right hand. (Say that three times fast!). NO,,,not that that that!).

Yeah,,,no problem with two things being independent, (your test). But it did take the second try. You want something hard?

I did get crossed up when also trying to do a backwards R with my left hand, and drawing an S with my left foot, while doing your test. THAT one is hard, and maybe should also be one of The Amazing Randy's million dollar offer! I'll get it,(maybe),,,but I may be cramped trying it for an hour straight! THANKS!!! And, if my wife walks up here and sees me in action,,,,,how do I explain that one?!

I play drums too, (since 12), and am athletic, so I admit besides the accordion skills I once had down, I had a head start.

BUT, I still have a problem tapping my stomach and rubbing my head!,,,,,,,,,OH yeah!,,,,it's the other way around, huh?,,,No wonder!

Our drummer, Marnie, talks about independence often, and does drills he makes up just to get better at it. I can't do what he does yet.,,,, Frustrates me!

Actually a Member Since 1996 or 97 (Number One Hundred Something).
