I dont read music and Ive never been in a position to need to.
Hey, my singer/acoustic guitarist, as tight and as good as he is, doesnt even know the chords/notes he is playing, he just says 'fifth fret', to which I say, 'oh an A' or whatever.
I would like to learn, but I seriously have little time, and what time I do have is for practicing with bands, gigging, golf, or (trying) to keep fit.
Maybe one day. I appreciate its a very good skill to have.
