Does anyone know where I might find a rough guide of how difficult it is to learn different musical intruments? I guess I'm specifically interested in the fiddle. I know music theory, I can read music (at least, if given indefinite time) and even mangled a trumpet in high school, but have never shown any aptitude (or, frankly, interest) in music. My artistic talents are visual. I guess it also depends on the complexity of the musci I want to play. Advice?
