The backing tracks on the CD are performed by international musicians who are specialists in their own fields, giving students an unrivalled opportunity to play with some of the best instrumentalists in the world. A second part (countermelody) has been provided for many of the pieces. This is often simpler than the lead line, and will expand the potential of this for small ensemble use. Many of these pieces are in the same key for flute, clarinet, alto saxophone, trumpet and violin, so they can be performed in groups. Chord symbols are provided on many of the pieces to encourage players to improvise. - Mike Mower
