Violin. It's easily one of my favorite instruments to listen to, and I was always fond of violin cover songs or having it mixed in to rock/metal.

I wanna be this guy

I used to play the violin

Theremin, so I could play the Star Trek theme. Nah, scratch that… harmonica, because I can take it anywhere.

Piano or guitar or both.

Piano! I know how to play a little but to be a virtuoso, wow. That would be amazing!

Bass guitar.

I already play, but not at the level you've described. The bass has a cool range of sounds, from funky. to Jazz, to smooth blues.

Piano, so much you can do with it.

bass guitar or tenor sax

I played a rosewood flute in my twenties. I prefer the guitar though. There are amazing things you can do on a guitar. Just listen to James Taylor.

I'm no virtuoso at anything but, my son and I both play guitar, bass and drums. Here's a brief video of me checking out a new guitar...

It would definitely be guitar because it’s so hard for me to play. I just love the sound of it. I found the trumpet and piano much easier to play.

Piano. I have been trying to learn blues piano. It’s a very long road....

Yes same here, I love the harp.. I also like the mandolin & harpsichord. Flutes are nice too, specially the American Indian flute songs.

Cello

Although I play several instruments, I would choose three that I do not play......the exquisitely expressive violin, the darker, moody cello, and the magical ring of the hammered dulcimer. I choose these with no consideration of monetary gain, only the sound of the instruments and my emotional response to them when played very well.....

Decades ago, I started to 'learn' how to play bass...it ruined the music I liked to play. I quickly forgot all about it and went back to the 'what's this?' version of music...a virtuoso of noise, if you will...the best compliment I ever received was that I play bass as if Lemmy Kilmister met GG Allin in a back alley and both were arrested for lewd behavior. I loved that one.

Viola, was in The Houston Youth Symphony when I was young. 1st Chair for 2 years ! Gave it up because the Navy had no use for a Viola Player...

The piano and the harp.

The guitar...

Watch "Maybe PRINCE HIS GREATEST GUITAR SOLO starts at 2.30" on YouTube

The violin, with my next choice being the piano.

Guitar. I am a poet, so that would be a different way to present my art

Saxophone. I've about 4 or 5 yr of instruction, but haven't seemed to master the instrument.

the tenner sexophone sorry saxophone

I really like all of them, but i think maybe drums ????
Good topic !!!!!

Wow, so many for violin. Guys, it sucks. Take it from me. It's one of the hardest to play (I mean physically difficult), sounds miserable when you start, difficult to master, expensive, temperamental... You have to LOVE it. Or don't bother. They're kind of a drag to carry too.

I'd pick something smaller and lighter like clarinet. Klezmer is bananas! Can't pick up and carry around a piano. Guitars are highly versatile but a drag to carry.

I've played all the ones I've mentioned. I want something I can slip in a backpack.
