But that's exactly it; I don't 'think'. I play, using techniques copied from some of the finest players ever : I throw my fingers at the strings, just as they do. OK, they're luckier than I am, mostly, but 'thinking' (whilst playing...) is a non-starter, for Humans at least. No, do the practicing. See (hear, listen to, record...) what's not right, find out how to correct it and do so (this may mean practicing something different for a while...). When it comes to 'playing', however, just throw your fingers to the strings and be lucky. Yes, I know; the more you practice (well...), the luckier you'll get, but in any case, forget the 'thinking' bit; Humans aren't built that way. Imagine a motorway drive; a car swerves across your path. Do you 'think' what to do..? I hope not. No, do the work, certainly, but give yourself the certain confidence that it'll be fine and it will be (or as fine as the diligence of your practicing can make it...).
