One morning in Adamant during one of her classes, a student was playing for her while she was across the room. She cannot see well now, but her ears and 6th sense about tone are so sharp, that she could immediately sense that there was a tightness in the right elbow. Upon reflection, the student was startled to realize that that indeed was the case. Move into tone, don t hit. Movement from inside the body goes out and the arms respond.
Fingers are just coverage.
Let it happen and the piano will sing. They keep me alive. I love to teach.
