I play violin, full sized (even though I'm not a teenager!), and piano.

I play the piano (4th year.) The flute (3rd year) and recorder (1st year) I only enjoy recorder!

I play the piano and I just had a concert!!!!

i vote for the mean stereo & other.
I did learned to play the guitar, keyboard & drums...owned all of the instruments at home but i sucked. so i rather be listener.
i sing only during karaoke sessions :p

i used to play with computer music software making ridiculous loop for fun, and i still like spinning/mixing music the olskool way (using vinyl/CD) although very seldom now...not enough time & enthusiasm unlike when i first learned to DJ years ago.

I "play" the keyboard type, which is piano :>

oh wow! Congratz, how did you do? any places? 1st?

I do not.
