This book was the stepping stone for me to understanding music. A musician friend of mine recommended the book and it turned everything around for me. I now play onstage and attribute all my music success to this book and the friend who recommended it to me.
The book was broken down in sections that really put it together for me at a rapid pace. The key for me... to understand that scales are really interval sequence (intervolic formulas?) and how C major fits into the bigger picture.
Thanks Steve!
