I mentioned in another thread about practicing that I am intentionally not working on much new material during this time but instead trying to play basic exercises to maintain some sort of playing shape but not stressing mentally or physically, concentrating on good technique and relaxation. This is a good time to really break things down and work on any technique issues. One of my old mentors always stressed one issue at a time and concentrating on just that. If I were having thumb problems I would do the simplest thing I could find that would deal with only that one issue until I felt comfortable and then move on.
I totally agree. I did a couple summers at Orford with Joel Quarrington, and if I could distill the vast, vast majority of his advice about bass playing down into one concept it would be something like -
Remember all those things your teacher told you to do in your first lessons? Good posture, good left-hand technique, use your big muscles wherever possible, don't squeeze, don't press with the bow, etc etc etc?
Yeah, do those things.
That philosophy got me through a master's degree where for the first year I was unable to practice more than an hour or two a day (or not at all if we had an orchestral rehearsal because I had to save my hands for that).
