Randy Aldcroft has written a great series of Twelve jazz duets for beginning Trombones in easy keys with range up to G-flat and down to low F. The duets are two pages each and are perfectly suited for two students or teacher and student. Mr. Aldcroft covers a variety of different styles in these duets:
Blues
Bossa Nova
Dixieland
Jazz Waltz
Rock
Bebop
Soft Shoe
Minor Blues
Jazz Ballad
Mixed rhythms
These Duets are a great way to learn the jazz styles in preparation for more serious study.
