"This book brings significant new insight to the art of jazz improvisation and should be an important addition to jazz pedagogy. Hal's approach to improvisation is a refreshing alternative to the usual 'learn your scales and good luck' methods. This bookaddresses the elements of rhythm, melody, and harmony in a manner that truly provides the student with a process and practice routine which enables the development of an improvisational technique so essential to the creative jazz musician."
