“Garage Band Theory is a must for any musician”
Rodney Crowell – 2 time Grammy Winner – Songwriter and Guitarist

“Something for every musician at any level.
This book inspires me to learn and practice more”
Sam Bush – 3 time grammy winner – Mandolin
International Bluegrass Hall of Fame

“A great resource for musicians young and old no matter what your training.
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 lets 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.
For less than the price of a single lesson, GBT offers a lifetime of learning.”
Alasdair Fraser – Scotlands Premier Fiddle Ambassador
