I've played piano for a few years. I never took lessons, but I learned everything I can play now by ear, and then memorized it. I can read notes, I just choose not to.
In fourth or fifth grade, in our choir/music class, we all had to learn how to play the recorder.
And in.. Second grade, maybe, I took violin lessons that I later gave up on.
In fifth grade we were given the choice of either going into band and having to pay for an instrument, or going into mentoring and later choir. I chose mentoring/choir, because they wanted to put me on trumpet and I know I would have been much better in percussion.
I'd like to learn how to play guitar. My dad has offered to teach me already, but never got around to it. xP
