Johnny Rector has been recognized for years as one of America's top jazz guitar writers. Here, for the first time, he presents an analysis of modern chord progressions, extensions, alternations, substitutions and a hands-on series of exercises designed to utilize and apply these important concepts to the guitar fingerboard. This book was written as a self-study guide to the intermediate, advanced and professional guitarist who has not had the opportunity to study material of this kind with a first-class competent teacher-artist, although such a teacher can be of great assistance in learning to apply the material. It shows unusual chord forms and progressions beyond the basics. Written in standard notation.
