Randy Aldcroft has written 3 volumes of 36 (twelve in each book) wonderful jazz duets for Trombones. These duets were written for the intermediate and advanced student interested in playing jazz. The range of notes gets higher and the duets get harder with each volume. All keys are "covered". The chord changes are included to help learn the structure and chord progressions, and so the duets may be played with a rhythm section if desired. These duets are perfect for the student and teacher to work on at lessons and several of them can even be programmed together as a medley on a concert or recital.
