Jazz Harmony: Necessary and Sufficient Conditions for Functional and Non-Functional Harmonies Paperback – March 6, 2019

Even the author declined the similarities with The Berklee Harmony System, but to me this is the summary of 4 Harmony textbook at Berklee. For those who been to Berklee, this is good to review all stuff you had studied. The rest of the world who never been to Berklee, this is good for you to overlook the whole harmony system they teach. Good book and it worth to spend 10 bucks.

A very hard read and it’s not just simple and easy to understand. The author should learn how to communicate better
