There is a lot of information contained in this manual. It is my primary guide for instruction. It contains over 200 lessons in the following sections: Theory, Technique, Fingering, Rhythm, Sound. CD's are included as well as a lesson plan. This is a great investment if you are trully self-motivated and do not have or want an instructor. The author is an instructor in Oakland, CA with over 30 years of experience. This book (one of three)contains the evolved lessons that he teaches.
