This book evolved from 40 years of teaching jazz composition and arranging plus 50 years of personal writing experience in the professional field. It is, therefore, a comprehensive study, covering preparatory activities, philosophical perspectives, listening lists, choice tune lists, all elements of composing melodies and chord progressions, arranging for small and large ensembles, enhanced use of rhythm sections, a sensitive approach to instrumental ranges, textural options, form, and more. Though a self-contained study, the book has the unique feature of leading the reader to other excellent books on the subject.
