I've always wanted to learn how to play the guitar, which is an instrument that has usually has 6 fixed strings on it.
What a great instrument -- and so versatile. Is there a certain kind of guitar or guitar music you want to play?
Not really, just the idea of it is really interesting. Especially how they are either electric or acoustic.
I guess acoustic would lend itself to more flexibility. It would be great to be able to just pick up something like that and make beautiful music! Do you have a favorite musician?
There's too many for me to have a real favorite. The difference between the two different types of guitars is how the sound is projected, which I found really fascinating. 
Very true. And I do like a variety of music. Do you prefer electric or acoustic? Or just depends?
I like acoustic more for the most part, as I like how the hollow wood sounds compared to the electric amp.
I do too. Hearing the Foo Fighters go acoustic on Skin + Bones made me fall for the music harder than had I just heard the electric versions of the songs.
Also the different types of strings make it sound different, as they can be made of gut, nylon, or steel.
