The late Dorothy DeLay taught violin at Juilliard for more than 50 years, and a list of her pupils - from Itzhak Perlman and Kennedy to Midori and Sarah Chang - reads like a who's who of the violin world. For more than 10 years, the author was granted access to DeLay's classes at Juilliard and the Aspen School, allowing her to craft this fascinating book that is both an exploration of the mysteries of teaching and learning and a feast of anecdotes about an extraordinary woman.
