For both alto and tenor, this set includes a dozen outstanding etudes for the higher-intermediate or advanced player written to sound like real jazz solos, not exercises. All solos are based on standard chord changes such as blues, I Got Rhythm, Satin Doll and more. There are two included CDs, one for alto and one for tenor, allowing both to read from the same book and have an accompanying demo/play-along CD in their key. This is a fun and challenging etude book for all serious saxophonists!
