Clarinet.

I used to play clarinet. I wish I never stopped and have often thought about the best way to pick it up again. I was pretty good in my day. Anyway, I was listening to WCPE, which is one of the best classical music radio stations I've encountered, and Weber's Concerto #1 for clarinet came on. It's probably my favorite clarinet solo piece of all time. I've always thought that in one of my alternate lives (I have many) where I singularly pursued clarinet performance as a career, it would have been my signature piece.
