(Amadeus). Abby Whiteside (1881-1956) developed a revolutionary approach to piano technique, the idea of a "basic rhythm" involving the entire body that allows students to express the essential emotional rhythm of the music, as well as to play without the risk of the injuries that frequently afflict pianists. Her ideas on piano pedagogy remain essential today.
Abby Whiteside's writing is a little dry for modern audiences but this book was a revelation for me personally and immediately improved my playing upon completion. It focuses on the coordination of the upper arms downward toward the fingers and rhythmic playing which underpins powerful analytical techniques. The best review I can give is that upon finishing I flipped the book over and started again from the beginning.
