I play percussion, primarily drum set/snare drum, but I've dabbled in mallet percussion (xylophone, glockenspiel, etc.) and I can play Tympani when called for, also all the fun auxiliary stuff (no mocking the Triangle, now!)
I also play the guitar a bit, as in a couple of songs my friends have taught me.
Oh, and earlier this year my friend and I cycled through most of the concert band instruments, trying them out after music class, and my best wind instruments were lower brass, especially trombone.
