Scales provide the basis for jazz improvisation and fill-ins. The scales presented in this book produce idiomatic sounds associated with many jazz styles. Bill Boyd explores the jazz scales and examines their potential, giving the player more improvisation resources. Each chapter includes charts with the scales written in all keys with suggested fingerings and a list of chords which compliment each scale. Music examples apply the scales to jazz chord progressions and compositions. Upon completion, the student will gain new insights into the practical applications of jazz scales and will be able to enhance performance.
