Cover of Bob Crawford's "SYMMETRIC CYCLES" music theory book


"Symmetric Cycles" offers new ways of stretching the melodic and harmonic boundaries of Modal Jazz, Blues, Pentatonic Rock, Latin (Montunos, etc.) Reggae, World Music, etc., creating sound colors that will open your ears in ways you may not have experienced before. It also is extremely useful compositionally in all musical genres--connecting chords in very unique ways, adding emotional sound colors to original musical works. As a teaching tool, I believe it to be very valuable for advanced students as well as seasoned players. You can preview several pages of the book on the website. Here is the web address: "Symmetric Cycles” can be ordered by calling Charles Colin Publications at 845-680-6880, their website or through my website And at Jamey Aebersold’s Jazzbooks site:
