Based on the keyboard works of J. S. Bach, each of the five volumes is available in five different versions - alto trombone, tenor trombone, bass trombone, euphonium, and tuba. Each version is customized for the individual instrument (choice of key, range, ornaments, etc.). This version can also be used by tenor trombonists to work on their low register.
Volume Five contains 24 etudes based upon the Six English Suites (BWV 806-811). -the publisher
