My favourite instrument to listen to is the Violin/Fiddle. It should be no surprise that Voltaire is one of my favourite artists and the original version of The Devil Went Down to Georgia as one of my favourite songs.
As far as instruments I play, I mostly stick with flutes, woodwinds, etc. Don't know why, but I've had luck with wind based instruments since I was like... 7, I inherited a flute from my grandfather, tried it out once and actually got sound from it, so I decided to learn how to continue playing it and I love playing instruments like that.
I also want to learn how to play saxophones and such, I'd love to do some classic style Jazz. It needs to make a comeback, this modern Jazz is nothing more than Elevator Music >_> Plus I want to play "Minnie the moocher" and a few more Cab Calloway songs at least once in my life. I freakin' LOVE Cab Calloway. Right now, I'm lear`ning Bass Guitar from my wife. I doubt it'll be my favourite instrument, but I'd still like to know how to play it. I know this is the eternal pipe dream, but starting a band would be awesome. She can play bass and classical guitar, and she & I both plan on getting a Violin and a Cello sometime and trying to learn them, it'd be equally awesome to starting a band to get into one of the orchestras around here. We actually have a pretty good orchestra in this state..
