If you read my interview with Steve Herberman, then no doubt you read about George Van Eps‘ influence on his playing. Often considered the pioneer of 7-string jazz guitar, Van Eps left behind a legacy and a legion of fans and players who consider him a major influence. He left behind the classic CD “Mellow Guitar” and the definitive three-volume book series Harmonic Mechanisms.

It would be safe to say that the Mechanisms series is the definitive chord study for guitar. It would also be safe to say that “daunting” is somewhat of an understatement. Well, perhaps “comprehensive” is a better adverb, but both are applicable. I suspect by the time you’ve worked through all three volumes you will be a master of chord theory and harmonization.

What’s In the Books?

Major, melodic minor and harmonic minor are the focus of his book series. What I particularly like about this method is that neighbor tones and some melodic cells between chord voicings are described in detail, which really helps with chord melody and comping. Wide-interval dyads are also explained here, which helps us guitarists break out of the barre chord and typical, stock chords mold.

All of your fingers get a workout as well, with methods that create finger independence and more control over your lines. Fingering diagrams are also extensively shown to aid in your progress. Seventh chords are shown a little bit in Volume One, and more extensively in Volumes Two and Three.

I highly recommend these volumes to anyone looking for inspiration and ways to break out of their comfort zones. Though it will take a significant amount of time to work through these tomes, the payoff is well worth the effort.
