Etudes and method books played had an important role in teaching technique and musicality for all musicians. Euphonium players have been using pedagogical materials originally written for other brass instruments such as trumpet, cornet, and trombone. Those materials have been very effective in helping euphoniumists learn skills to play idiomatic nineteenth and early twentieth century repertoire. In recent years, many solo pieces for euphonium demanding advanced techniques have been composed. The difficulty of these solo works for euphonium has increased dramatically in the second half of the twentieth century. Traditional etudes and method books do not cover all the necessary techniques to play this modern repertoire. In the last two decades, many collections of etudes have been written specifically for euphonium, and several of them are technically challenging and aimed at advanced euphoniumists. This trend can be seen in the United States, France and England. In this paper, traditional standard pedagogical materials currently used by euphoniumists will be evaluated. Recent publications of pedagogical materials written exclusively for euphonium after 1990 will be introduced, and effective uses of old and new pedagogical materials for current euphonium players will be presented. An annotated list of the latest etudes composed exclusively for euphonium will be provided at the end.

Doubling is defined as playing two instruments. It is becoming increasingly necessary for low brass musicians to double in the course of their careers. Euphoniumists often learn trombone, and trombonists learn euphonium. The instruments share several surface similarities but also differ in many significant ways. Interviews with six professional doublers highlight strategies for learning, teaching, and performing on both trombone and euphonium. Slide and valve technique, adjustment of intonation, tone quality, air usage, repertoire, and skill maintenance are all addressed. Trombone literature comprises a large part of the euphonium repertoire, due to the fact that most trombone pieces can be performed on euphonium. Euphoniumists should avoid playing pieces that require glissandi or extremely loud dynamics to be effective. Euphonium solos are generally too technical to be practical for trombonists to perform. Grøndahl's Concert pour trombone et piano ou orchestre is a standard piece for both instruments. When performing the piece on either instrument, it is helpful to practice the piece on both trombone and euphonium in order to tap into each instrument's strengths.

This dissertation presents a categorization of existing methodologies of upper register development for euphoniumists with evaluation of effectiveness and current use of these methodologies. The purpose of this study is to provide euphonium musicians as well as educators with essential references and guides to applicable methods for developing the upper register more effectively with greater efficacy. The assessments of current methodologies include three steps: categorization, summarization, and evaluation. To support the significance why it could be more beneficial than the methodology alone, the dissertation will include the examination of the aspect of biomechanics and ergonomics, suggestions, and discussion of particular issues of the upper register.

An examination is conducted of the life, career and musical styles of Richmond Matteson, an influential jazz euphonium and tuba performer of the twentieth century. The study includes a brief history of the euphonium's role in concert bands. A description of Matteson's background as a musician and clinician including education, influences and career changes will also be discussed. Analysis of Matteson's improvisational style and a transcription from the recording Dan's Blues is included. A formal analysis of Claude T. Smith's Variations for Baritone is provided, as well as a brief biography of the composer. Matteson's stylistic traits which Smith employed for the composition of Variations for Baritone are illustrated. The conclusion calls for further study of jazz styles by euphoniumists with more frequent performances of Variations for Baritone. Appendices include lists of Matteson's compositions and arrangements, a selected discography and a list of clinics and performances from 1982-1992.
