Campbell, Gary: Connecting Jazz Theory - All Instruments

This text suggests a more connected process for expanding the jazz vocabulary. Improvisational devices are presented as derived from diatonic scales, the harmonic and melodic basis of mainstream jazz.

Michael Brecker highly recommended this book, calling it useful and insightful...for all musicians who wish to expand their harmonic range and improvisational abilities. Also endorsed by James Moody and David Liebman.
