This is a book by Hal Galper that I’ve been getting into lately. The subtitle is: From Bach to Bebop – A Corrective Approach to Jazz Phrasing. I really feel my jazz lines have improved since reading this and working on some of the exercises. The book concentrates on the importance of chord tones, tension and release, how to treat the “one”, etc., etc. There’s also a lot of philosophy on hearing, practicing, rhythm, swing, etc. Highly recommended…check it out!
