The reviewer above me stated that this new book is similar to 'The Chord Scale Theory and Jazz Harmony' by Barrie Nettles, Richard Graf. While not untrue, this book is makes CST obsolete.
CST was so eloquently writen, sort of like an exercise in reading coprehension. It's a great book, but you realy have to read between the lines, over and over again.
This new book is a real joy to read and easy to understand, yet much more evolved and expanded.
The language is clear and the explanations are far deeper so you won't be left with unanswered questions.
Btw, this is a theory text, Im not sure why the reviewer above me said it was practice orientated.
