Each musical example has a single note improvised melody line with the chord progression 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 downloadable audio files are recorded with the saxophone playing the melody line along with a rhythm section of piano bass and drums. All the examples are recorded with the saxophone and the rhythm section, as well as the rhythm section with out the saxophone and with the more difficult examples the rhythm section is recorded at a slowed down tempo.
