piano fitness is training. learning to listen trains the mind/body connection. the intended sound feels easy and relaxed. mindful repetition develops muscle reactions that become automatic. hearing the sound and feeling the motions=mind/body connections. the relaxed thumbs seem to give support to the other fingers. letting go is the difficult part.
