Itzhak Perlman, Kennedy, Midori, and Sarah Chang were among Dorothy Delay's students during her five decades as a violin teacher at Juilliard. For more than ten years, the author was granted access to DeLay's classes and lessons at Juilliard and the Aspen Music Festival and School, and this book reveals DeLay's deep intuition of each student's needs. An exploration of the mysteries of teaching and learning, it includes a feast of anecdotes about an extraordinary character.
