One of my exercises is this: place all four fingers of the LH on the 2nd course. Then, select one pair of fingers at a time, and move them in a pattern while keeping the other pair of fingers fixed.*
In doing this exercise, I find that after movement is initiated, I seldom get con- fused about which fingers should be moving and which should be stationary. It is only during initiation of movement that I accidentally move a wrong finger. I also find that having recently moved a pair of fingers is quite conducive to initiating them again. I wonder whether anyone can describe a physiological basis for these two phenomena. * There are six possible pairs, 12, 23, 34, 13, 24, and 14.
