In current tuba and euphonium writing there is considerable gap in technical difficulty between tuba-euphonium quartet literature and wind band literature for the secondary and collegiate musician. As the tuba and euphonium profession becomes ever more challenging, there is a great need to establish a curriculum for building technical facility. The importance of chamber music as a pedagogical tool is well documented and has been shown to develop technique, musicianship, and many other skills. There are a number of researchers whose work demonstrates the numerous benefits of including chamber music to students' education. However, because of the lack of small ensembles for tuba and euphonium players there is a need to utilize the tuba-euphonium quartet. This study provides a brief history of the tuba-euphonium quartet to give context to one of music's newer chamber groups. Selected works for both wind band and tuba-euphonium quartet are graded with a rubric to assign an appropriate difficulty level. An analysis of the selected works gives educators examples of how to take advantage of each work's unique technical aspects. Included in the appendices are grading breakdowns of fifty wind band compositions and forty-three tuba-euphonium quartet works.
