When I saw Joyce yesterday in addition to updating her about stuff, when I was playing my flute with her we talked about the difference between holding the keys down really really firmly versus more gently.  It was yet another reminder of how very small things can make a difference.  I think that's really one of the keys to Feldenkrais is understanding that small differences can lead ultimately to change.  We talked about how if you do something a little bit differently than what your body is used to it gets all kinds of things happening in your brain on the processing level.  That's why small things can make a big difference.
