ts. Great primer for learning basic skills in major and minor keys. Advanced players will want to work on double-timing," playing "outside," and "side-slipping" in all keys at comfortable tempos. The CDs contain 30 extended tracks of recorded background. Special tracks have Jamey Aebersold playing various exercises and soloing on his saxophone with actual cuts from Volume 24 so you can hear and see how to use this set. All exercises and sax solos on the demo tracks are transcribed and written out in the book! Pick a different key each day/week/practice. Rhythm Section: J. Aebersold (p); John Goldsby (b); Charlie Craig (d)."
