Re: Any tips for 'useful fidgeting'?
I'm wary of 'fidgeting' in public for fear of annoying others.
My favorite thing to do in these cases is to transcribe something. I cool groove, a solo section from trading fours, etc. I find it better to do this on a bus, on a plane, in a car (now I'm hungry for green eggs and ham...) as I would prefer to use practice time to actually apply these things to my playing.
