British composer/music pedagogue Paul Wilkinson has written a new introduction that offers multiple points of entry to Levy’s work to make this text more accessible for a new generation of students, performers, and theorists.

This book actually provides a theory of harmony. One of the major musical minds of the twentieth century, Ernst Levy was born in Basel, Switzerland, in 1895.

This book's purpose is to investigate tone in terms of musical values and in many ways is an outgrowth of a course taught by the authors and some of their colleagues over the last ten years.
