I play the Clarinet and Piano, but have neither of the instruments on hand, so no, I can't really demo them.
On the clarinet, I'm moderate in experience, and would say I am pretty decent, however on the piano, I enjoy writing music to sheets based off of (REALLY BASED) modern and current music, along with older and not-so-current music. It get's me places when I play a composition of Lady Gaga, Justin Beiber, Bruno Mars, Vanessa Carlton and Aha!.

I play bass. Don't know how well I play. Better than most. But that's not hard.

i play: drums, guitar, bass, and keyboard. as far as how well i play, it depends on my mood generally. i'd like to think that i can play somewhat well though!
http://youtube.com/mooiamme has a few videos of myself playing.

Piano, kinda.

i can play guitar and sing pretty well, as evidenced by these videos:

Sun Kil Moon - Carry Me Ohio

Evanescence - Hello

i started out on a (lined) fretless bass, and can play drums and keyboard.

oh and i can play harmonica, though mine is really dusty lol.

I can play euphonium really well(6 years), I'll hopefully have some videos up sometime. I can also play trombone decently, though I quit learning because it was hurting my euph tone. I guess it's worth mentioning I've started composing, just writing for solo euph right now but I'll eventually write for other instruments. Also, I like music theory :P

I've been told that I can beatbox very well.

Standard drumset with double bass. I don't know how well, as I always play alone.

I played trombone in the school band for... 6 years? I'd like to think that was enough time for me to get decent with it, though I don't like it much and probably won't go back to it.

I also play bass guitar, which I enjoy considerably more than the trombone, though I haven't gotten the chance to play in quite a while. Back when I was actually playing though, I played on stage a couple of times, so I must have been at least competent.

nothing! can you believe it?

I've forgotten how to play all the instruments I used to. But I used to play bass clarinet, clarinet, and trumpet pretty well.

Drums - 13 years
Guitar - 5 years. Lots of gaps.
Saxophone - 1 year

I play violin and piano. Rather well according to everyone who's heard me play, but I still doubt it.
(played violin both in orchestra and solo, piano only solo)

also i pick up the guitar in my room from time to time but yeah

I play the electric guitar and theoretically I guess I could play an acoustic guitar. Over the two (three??) years I've been playing I haven't learned how to do much more than hitting power chords unnecessarily fast.

Your final blog ever? :(

I'm literally the same as Mordi. Except that I've played with other people a couple times, and know I can't keep time.

I also played piano for 8 years, but all I can do is read music.

Trumpet and euphonium - though I haven't played either of these in a couple years. Euphonium was the most comfortable I ever got with an instrument
Guitar - moderately well
And then-
Glock, autoharp, (toy) piano...
And then I've also made a couple, so they don't really have names (so I should post videos). First is a popcorn tin... guitar? It has 8 strings, with the top two being doubled.
Second is a cookie tin banjo ukelele
Third sounds kind of like a wind chime. You're supposed to play it over a tub of water, and then dip the chimes into the water to shift the pitch

I think that's everything

I bought my first guitar when I was 18. I've never taken any lessons on how to play. I mainly play just songs that I make up. I would say I am probably a novice guitar player.

Is vocals an instrument?

If vocals count, then there's mine.

Little bit of piano, harp and recorder.
