For all levels, instrumentalists and vocalists. Hear Liebman solo over every scale listed in the Scale Syllabus. He solos on two versions of each scale. The first is slow/simple and the second more complex/fast. Stereo separation allows you to practice and improvise too. Liebman is featured on one channel, Jamey Aebersold on the other. Piano and guitar players can accompany or solo. Not only can you hear the different scales, you can practice with them by turning off the sax or piano channel.
