This book is intended to answer guitarists demands for my lessons. Ultimately, it depends on who will learn it and how they utilize my method. Over the years, I had been asked to compile my guitar method book, but I was very reluctant to do so until I completed my improvisation book Yamaguchi Improvisation Method (New York: Masaya Music, 2012). Because after all, my priority is to teach music, especially improvised music --- not how to play the guitar. Though this book required a huge amount of work to complete, I finished it for all my fellow guitar players, who regularly use my The Complete Thesaurus of Musical Scales. The YAMAGUCHI Guitar method in this book is highly original and much different from most books in today s jazz pedagogy. This is a new kind of guitar method book that will leave no student behind if you interpret my words correctly. I hope the YAMAGUCHI Guitar method will guide you to unlock melodic possibilities and broaden your musical vocabulary. GOOD LUCK!
