Marty d: your comment on typing may be more relevant than you think. If like me you are not "touch typing" there's a limit to what you can do: to do better you've got to go back and get the basic fingering right. I've found on left hand if I don't get a fingering that moves easy from one note or chord to the next there's a "stall speed" I can't break. The first time I looked at one Segovia transcription, the fingering looked totally illogical: then i realised on each fingering he was "setting himself up for the next shot" like a snooker player.
