The connection of ear to touch is critical. It is also extremely difficult to achieve because of the many distractions that interfere with their direct connection. Of these distractions, instrumental technique is the first offender: we are too likely to remember how to play a piece rather than to hear it as it is coming forth. For anyone listening, whether player or audience, familiarity is the next greatest distraction. I have already heard it; I know how it goes; I don't need to really pay attention.
