Books like Chord chemistry by Ted Greene

A practical guide for guitarists seeking to refine technique, expand harmonic knowledge, and develop a personal style, presented as concise essays rather than step‑by‑step drills.

Author's Description This book clearly relates the fretboard to the same musical principles all professionals on any instrument use, teaching the practical hands-on basics without glossing over the theory every guitarist should know. It does not invent its own terminology or pattern numbering system, a problem that has lessened the value of many books like this in the past. The CAGED-based fretboard system used has world-wide recognition and a long historic basis, refined and tweaked in Musicians Institute curricula since 1977 by hundreds of instructors after its introduction by Howard Roberts in the early 1970s. You'll cover everything you need for a rock-solid foundation, including modes and slash chords. You'll understand and play (anywhere on the neck!) any scale or chord you encounter or imagine. Besides offering you a chance to completely grasp the guitar, this method assures you will be able to communicate with other trained musicians no matter what their instrument. The book was designed for use in three arenas: private lessons, classroom instruction, and personal study by the motivated individual. There are 22 short chapters of very gradually increasing difficulty, suitable for teaching in 20-30 minute time frames. Each chapter has modest written and playing assignments, with all the answers in the back of the book. The text was written specifically to be concise, informative, and fun, yet easily understood by non-native English speakers.
