This is non Academic, practical, useful theory for living-room pickers and working musicians who want to be able to think coherently about music in order to ask questions and understand answers about the music they want to play.
The stuff in GBT is about understanding The Beatles and The Rolling Stones, Cole Porter and Duke Ellington, The Grateful Dead and Vampire Weekend.
It's NOT about analyzing Bach Fugues.
It was written for the 99% of musicians who are NOT music majors by a incorrigible honky-tonk guitar player who plays by ear ... but understands the relevant vocabulary and what's sensible and useful for MOST players.

"Garage Band Theory is a veritable encyclopedia of useful tools and tips.This book lifts the lid off the "black box" of music theory and let's the light shine in - and in a fun, practical way.
This is a book which should be left handily lying around the living room, bedside, studio, classroom, (restroom?) - ready to be dipped into at any time for reference purposes or just to improve or refresh one's fluency in the language of music.
A great resource for musicians young and old no matter what your training. For the price of a one-hour lesson, GBT offers a lifetime of learning."
