I used to think every "real" musician could play whatever tune might be playing in thier minds. Just like humming or whistling to a tune, playing it without having to learn it or figure it out. Some of the stuff I've seen or read more recently has been sort of encouraging to me since it seems I'm far from alone in having to work stuff out before I can play it. I mean I can get along fine with my familiar patterns and stuff, but if I want to do some harmony or fills that are out of the ordinary I have to experiment for a while and sort of work that to the point of being comfortable. Do you have to work stuff out, or can you just lay it down as it comes to you? How about double stops, chords, or whatever? Just how rare is it for people to be able to just let it out as they hear it?
