How many instruments do you play?

I've been slowly teaching myself acoustic and bass guitars. I recently have also signed up for a music theory class at my college and it's very heavily piano-oriented so I wouldn't be surprised if I try to pick that up too. Oh, do MIDI Keyboards and synthesizers count? hahah Bass guitar's my main focus though, I find it the most fun.

I play two. Piano and guitar. I try to sing but I sound as bad as Courtney Love haha.
