The book that launched a publishing empire! Well, it was the first one I wrote, anyway. At the time, I couldn't find any particularly readable books on guitar music theory for my students, so I decided to write my own, by cracky! It's all here: how notes become chords, how chords group into keys and how everything comes together in the Circle of Fifths, the cosmic nutshell of the entire musical universe. But I go easy on you by (1) starting with a general survey, just to get you playing some different chord families, and then (2) returning to the beginning for a more gradual, brick-by-brick approach that culminates in a flash of insight (page 100). Dan Miller, publisher of Flatpicking Guitar Magazine, calls it "...the best presentation on this important theoretical tool I have ever seen."
