"Something for every musician at any level. Especially helpful is the musical notation and tablature for a variety of instruments. This book inspires me to learn and practice more." - Sam Bush

"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."
