100 Ultimate Jazz Riffs for Guitar by Andrew D. Gordon & Joe De Sa consists of, as the title suggests, 100 Jazz riffs based on common chord progressions used in jazz such as the II-V-I, III-VI-II-V etc. There are five separate sections: Jazz Swing, Jazz Ballad, Jazz Funk, Jazz Waltz and Latin Jazz. Each musical example has a single note improvised melody line. At the end of the book there is the chord progression for the popular jazz standard "Blue Moon" showing you how to use various examples from the 100 riffs to create an improvised solo over the chord progression. By demonstrating this technique you can pick most jazz standards and create your own improvisational ideas using the book. The audio files are recorded with all of the examples recorded at normal tempo (both with and without the lead solo with rhythm section accompaniment of piano, bass & drums) and most examples of the rhythm section at a slowed down tempo. An absolute must for guitarists learning and playing various jazz styles.
