I don't play any instrument, but wish I could/intend to try to learn something.

I do however do custom guitar pedal effects and mods, and have done some various bits of studio hacking/engineering work (when I still lived in Detroit I helped a well known artist get his first PC-based/digital mixing board up and running).

I taught myself acoustic guitar. First, I learned from books and websites. Then when YouTube came out, I found a lot of very good "How to Play Song X" videos on it. I really enjoyed learning to play. Spending 5-10 hours a week away from my computer, and not looking at a screen for most of that time, significantly boosted my productivity and improved my morale. I was pretty burned out and looking for something to do besides computer work, and reading about computers, when I started picking it up. I haven't played in a few years, though. As I got older, I kinda lost interest in music (both listening to and playing).

I used to play saxophone - but I sucked. I also play a teeny little bit of piano.

Violin. I could have gone professional, but decided that I'd enjoy it more if I kept music as a hobby, and that computing/mathematics paid better for less work anyway.

It's like cheating at music.

Piano - I really like how versatile and consistent it is. If I were to learn another instrument, it'd definitely be guitar.

I play guitar very poorly. When I'm stuck on a problem I'll run scales for awhile until the answer hits me.

Guitar - jazz and blues. I used to play pro and then "found" computers :)

Awesome. If you don't mind, do you have any music links of you playing I can listen to?

I don't have but 1 or 2 songs today online and those are not ones I'm too proud of lol. I did just buy a new Eric Johnson Fender Strat and have started getting back into practicing though :)

I dont play music, but I love to listen to it. HipHop, R&B, Pop, Jazz, Classical, Blues, Rock, everything. I too have noticed that playing music is a consistent trend for many.

Electronic drums, banjo, guitar, piano, trumpet -- in order of increasing skill (not that it increases to any significant level).

piano and saxophone(not at the same time :) ) Though recently I have been thinking of taking up bass guitar.

Play piano and guitar; try to sing too as I write music and someone needs to sing it.

Expert Rockband drums... that counts right?

Me too. And absolutely it counts; VB programmers are still programmers aren't they?

I play the guitar.

Clarinet

piano, guitar...not well

guitar hero!
