I play violin and, to some extent, keyboard. I've been playing the violin since I was 7 (I'm 18 now), and I started playing keyboard when I was about 10 or 11 but didn't play it for much of high school.
Violin, I got my grade 8 in March last year, I played in my high school orchestra and ceilidh band and I'm now playing in the orchestra at uni. Keyboard, I've never really played in front of other people, with the exception of music lessons I had at school, but someday I'd like to get good enough to join a band.
I did used to play the recorder, too, but since I haven't played one since I was about 6 years old I'm not sure that counts.
