Careful attention has been paid to endurance, range, and modern performance requirements. As such, these etudes can be used as a primary teaching source, or as supplemental material. Depending on the intended use of these etudes, they may be learned and performed in chronological order, or in a different order as suggested by a private instructor. Additionally, these etudes are also offered in identical versions for small group instruction purposes, transposed and minimally adjusted as necessary, for tuba, euphonium, trombone, horn and trumpet. Etudes appear in the same order, with the same markings, in each book. Bass trombonists are recommended to use the trombone book for slide technique, and the tuba book for trigger technique.
