As a technique builder for jazz improvisation on the violin, this book is comprehensive. It provides: the arpeggios for 7th chords with useful fingerings, jazz scales, and rhythm exercises to develop technique. Improvisation is often taught with various scales. In addition, this book teaches the 7th arpeggios of jazz chords in several positions to help navigate the fingerboard and get to chord tones. A short jazz theory section describes the reasons that the 7th arpeggio is essential to improvisation. You can use these notes in many sequences and rhythms to improvise jazz music. The exercises are appropriate for beginners with good shifting skills. Three octaves are provided, but beginners can start with one or two octaves. Since students of jazz violin often do not have a teacher for specific jazz improvisation technique, this book provides useful, wide-ranging suggestions to help a developing jazz violin improviser produce the sounds expected in jazz and improve their musical techniques.
