Kyle Harris,
That's interesting, I did the same thing, took piano lessons when I was young, despite my friends knocking on my window, trying to get me to come out and play with them on saturday mornings when my teacher was giving me lessons, but, I don't think I would present myself as having been studied or schooled at much of anything at age 21.
Especially music, golf, marriage or chemical engineering.
You state that Beethoven's 5th has been altered.
Could you cite for me the dates it was altered, and by whom ?
I'm always willing to learn.
