Well, I come from a very musical family -- everyone sings, most of us play an instrument -- and in addition to that, I have a fair amount of classical training from being heavily involved in the music departments at my schools all the way from the fifth grade through my Freshman year in college -- during which time I majored in music. While I was majoring in music, I was a member of the choir, the classical guitar ensemble, and the vocal jazz ensemble -- which was the highest level vocal group on campus. You've never seen a piece of music with difficult harmonies until you've looked at a vocal jazz piece. By the way, this is completely aside from private lessons, theory, ear training, the recital semminar, and my non music-related classes.
Anyway, It's been a year since I stopped performing on a regular basis. I'm a little bit rusty, but once I start singing again, I should get back into shape pretty quickly -- it's just a matter of warming up daily, which I haven't done in over a year. I'm going to a new school in the fall, where hopefully not all of the talented musicians will be locked up in the music program. There's so much work involved in majoring in music that most music majors don't have time for any sort of a side project, and it's side projects that I'm really interested in; I want to play Iron Maiden and Nightwish, not Schubert and Mozart.
