I'm not saying this to sound pompus, because I truly have a point here. I have played the piano for 20 years now, and I'm pretty damn good (not a concert pianist by any means). The piano teaches you a lot of fundamentals of music, such as the ability to read both clefs and coordinate your left and right hand, as well as many of the not so unique things to the piano you pickup about music in general. That being said, I never felt that any instrument was out of the question with a good amount of practice, but I have always wanted to play the drums because drummers abilities to move all limbs independently, sometimes at completely diffferent rythms amazes me, and i admire the amount of coordination required to do that. You use a foot pedal with the piano, but its in conjunction with your hands, not independent usually.
