Playing for others is an act of fundamental generosity. It's like telling someone a deep secret, letting them know how much you love the sounds you are playing, or how interesting it is to move from sounds that you love through others that are more puzzling.
If every time you play you are in touch with your response to sound others will feel your involvement and will support it with their rapt attention. Sometimes people come up to me and recall specific pieces that they heard me play thirty years ago.
Whose ear do you aim to please?
