I hate these threads... (at least those which ask what instruments you play), because I feel so much like a show-off.
Piano: 9 years
Violin: 6 years
Drumset + Percussion (including Mallets): 4 years
Tamburica (a kind of Guitar): 4 years
not playing instruments which require a lot of breathing, because I have Asthma (or had, at least)
So what do I play? I don't really know for sure, but the hardest piece I've played for piano must have been Chopin: Fantasie Impromptu (started learning it 1 + 1/2 years ago), on Violin I'm currently playing Max Bruch Violinkonzert, and for Drums I'm learning some pieces I don't really know the name of ATM, but I played along Space Truckin' by Deep Purple last concert.
I'm playing violin in a group which is quite well-known in this area. Also, won 2 second prizes with piano at Prima la Musica (2001, 2003) and several 1st with mallets and drums (in a group though, where I'm the oldest one). Heck, I'm saying too much :x
Music just is my thing. Hardly anybody in my area can beat me to it
EDIT: Holy... I know there's a video in the web out there somewhere that shows me playing Fantasie Impromptu. By Oberpullendorf TV, I played it at the Pullenale 2007, I think on the 27th of September. But heck, I can't find it...
