I play French horn and electric bass. For my own amusement when no one can hear, I'll play the piano or my 12-string acoustic. I also sing and am pretty good with the egg shaker.

Surdo! (I'm the tallest, second from the right.)

The amount of instruments I can play is limitless just so long as you're the type of person who enjoys sounds similar to cats being tortured.

I'm a guitarist.
I'm lucky to be in a professional band with two singers who have had chart success in the English Bhangra chart.
On the side I'm in a very serious (attempted) comedy band. If you have 5 minutes and are bored:
The Vaguely Mysterious Rebelitos

It needs to be said that I wasn't "practicing" per se, I was just playing along to music I like and I just couldn't get enough of it. I'm really not into specific exercises just for the sake of practice, I need to have fun while doing it. Unfortunately I ran out of fun metal songs to play, haha.

like 3/4 of the world, I also play the guitar and say my hails to Hendrix each morning :p But i'd rather say that i play music with a band.
If any of you guys like to get REALLY high or listen to music that makes you feel high, please have a listen to my band Bendar Sp�nir and check out the song Syrutta Pissi or �tfer�(especially this one if you like the Hammond organ). I really like playing psychedelic jam music, so i can't say that i spend much time with actual practice(scales and stuff).

Guitar/vocals/electronic things.

I'll tell you in advance it's a little strange. :P Maybe you like that sort of thing.

PS. If anyone wants to submit music for the GOG user podcast, please do.

Euphonium FTW!
Best instrument ever, although generally unknown.

I play guitar and teach as well like everybody else :).. But it's my life rather than something i just do on the side for fun... Check out my Youtube videos if you're bored... (It's alot of Metal/Shredding!)

I'm an (electric) bassist, though I'm learning to be a drummer. I CAN play guitar and a little keyboard, but I wouldn't say I'm a guitarist or a keyboardist ;) lol
Apparently there aren't many bassist or drummers on here. Although that's probably true of most places lol :)

Keyboards / synthesizer
I played trombone in middle school.

I also, like many others, play acoustic and electric guitar. I began playing about 8 years ago, joined a few bands but they all fell apart after a few months :( I like to play all kinds of music like funk, blues, metal/rock and some spanish stuff lately
