Serendipitous Coaching
I had a piano lesson with a visiting pianist who regularly returns to Tulsa, having formerly taught at the University of Tulsa.
I performed two Chopin etudes for him and was given constructive criticism, for which I am grateful.
The lesson took an unexpected turn when the instructor asked me to play another piece for him, so I used the opportunity to receive comments on a third Chopin etude.
Unanticipated opportunities to learn are always helpful.
