abstract: Electro-acoustic compositions throughout the twentieth-century have flourished due to the modern advancements and improvements in technology, including image based interactive software. This project aims to reveal how three composers of different backgrounds utilize the use of euphonium in combination with live interactive electronics. To this date no known works have been composed for this instrumentation. Advancements in the development of audio software and hardware have helped to improve and rapidly evolve the inclusion of live electronics including the use of performer-triggered events, audio processing, and live electronic decision-making. These technologies can be utilized and explored in various ways. Three composers have been commissioned to each compose a new work focusing on using the timbre of the euphonium in combination with explored electronic sounds, unplanned sounds of nature and the use of the human voice. Each work is performed and examined by the author in order to further explore the electro-acoustic properties of this genre, how they communicate and interact with one another, and how the electronics interact and meld with the sound of the euphonium. Compositional elements in this project include but are not limited to the use of pre-recorded natural and “un-natural” sounds, and the manipulations of both pre-recorded and live sounds through the use of performer triggered events using visual programming languages such as Max/MSP and looping pedals. / Dissertation/Thesis / Zero Circle-Justin Rito (Live Recording) / Warrior-Brett Copeland (Live Recording) / Petrichor-Grant Jahn (Live Recording) / Doctoral Dissertation Music 2017

The four-valve automatic compensating system as developed by David James Blaikley has become an integral part of the professional euphonium in use today. While the Blaikley system was designed to allow a euphonium to play chromatically down to the fundamental pitch of the instrument, it was hardly the only design to do so. Using a historical analysis of euphonium valve systems, the case is made for why Blaikley's design has been widely adopted in the face of criticism about the four-valve automatic compensating system. The analysis also clarifies the viability of Blaikley's, as well as others', euphonium valve system designs based upon the four factors of intonation, range, intuitiveness of use, and weight. These factors are further explored in a rubric in order to quantify the results of the analysis.

I present strategies and methods for teaching fundamentals of music theory in the context of the private music studio through a variety of techniques and research. Beginning with a background in educational psychology, examples of behaviorist and cognitive teaching models are presented, and how each applies to teaching music is explained. Two detailed examples of actual lessons are presented, coupled with musical examples, to describe both the process and the concepts that can be presented. A qualitative experiment based upon the learning styles of three music students and the effect of different teaching styles when teaching the same concept is presented and discussed in detail.

The tenorhorn and baryton (euphonium), as members of the valved conical brass family, were highly regarded by Oskar Böhme (1870-1938) and Victor Ewald (1860-1935). This study examines the role the tenorhorn and baryton played in selected works by these two composers of the Russian Chamber Brass School. A chronology of the research leading to the discovery and naming of the Russian Chamber Brass School is included as well as a discussion on brass chamber music performance practice both then and now.

Females make up the minority in professional euphonium playing and teaching roles in the USA. The purpose of this research is to unveil the reasons behind this imbalance and to discover potential impacts females experience as a minority in the field. Research methods included sending a questionnaire to professional female euphonium players and teachers to document the experiences of participants. A secondary purpose of this study is to further document the existence of past and present potential female euphonium role models. Through a discussion of possible origins of and reasons behind a perceived lack of female euphonium players, I am seeking ways to achieve greater parity by garnering a more comprehensive understanding of the challenges faced by female euphonium players.
