"Garage Band Theory is a must for any musician." - Rodney Crowell -
"Don't be put off by this giant book - Duke's got the secrets of the universe in here. Quite simply, this is the most comprehensive book on music theory I've ever seen." - Bill Payne (Little Feat)
"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." - Alasdair Fraser
Loved the style of the writing in this book. Made the theory understandable and work for me. Does it better than most theory books do for me. I've studied this stuff for years and worked a lot out but I found this really helped pull it together nicely.
