The extended Lydian Locrian theory of harmony (ELL) is a system of analyzing harmonies and progressions according to their position along a vast spectrum of colors. The musical premise is that chords and progressions spanning upwards around the circle of fifths sound brighter, whereas chords and progressions spanning downwards around the circle of fifths sound darker. This simple premise gives rise to a complex but unified system of harmonic structures and relations, a system which provides a valuable tool for analyzing and composing music, especially of advanced tonal genres. ELL not only provides fruitful techniques for analyzing certain kinds of traditional harmonies and progressions but also provides a framework for discovering more exotic and colorful harmonies and progressions.

Starting in the mid-2010s VR's high cost of entry became low enough for consumers and artists to explore and experiment with the technology. There have been a few VR operas developed by medium to large sized teams such as Michel Van Der Aa's Eight (2018) and Alexander Schubert's ⁂ASTERISM⁂ (2021), but no widespread work has been produced by a small team comprising only a librettist and composer. Vessels engages in this process with a libretto written by Bea Goodwin and music, audio processing, visual design, and programming by Christopher Poovey. The first step in the process of creating Vessels was the creation of the song cycle Songs from Vessels for soprano, extended tenor, flute, bass flute, A clarinet, viola, contrabass, percussion, and live electronics. These songs are the basis of the micro-opera Vessels which presents recordings of the songs with live processing alongside two songs exclusive to the opera in a VR environment with immersive projections and audio. The development of an ensemble and electronic work along with a VR micro-opera necessitates the implementation and creation of software. Both the Grainflow and cpDelayNetworks packages for Cycling ‘74 Max are pivotal to audio processing in both versions of the work. In …

Based on the poetry of Jehanne Dubrow, professor of English at the University of North Texas, Stateside: An opera in one act uses the mythology of Penelope and Odysseus to tell a story of a modern day military wife. David T. Little's opera Soldier Songs, Sarah Kirkland Snider's song-cycle Penelope, and Stateside are dramatic musical works influenced by the genre, instrumentation, and formal structures of popular music that broadly deal with the emotional and internal elements of military life. These three works prioritize narrative structure of the text in relation to character, and employ elements of popular music harmony, melody, and structure. The critical essay analyzes selections from Soldier Songs and Penelope and explains the compositional process of Stateside. The creative document consists of the full score of Stateside: an opera in one act.

Untune the Sky is a collection of ten original preludes, dances, and songs for microtonal viola da gamba in 7-limit just intonation with voice and live electronics that incorporates elements of Baroque music, traditional Irish dance music, extended just intonation tuning theory, and live electronic audio processing techniques. This thesis thoroughly describes the work and contextualizes its relationship to its historical and contemporary influences. The first sections explain why extended just intonation and viola da gamba were chosen as the central elements of the work. This is followed by a description of the structure, instrumentation, notational conventions, and intended performance practice of the work. The final section contains a musical analysis of the form, harmony, and structure of each piece in the collection. For researchers and interested performers, Appendix A contains a brief catalog of existing microtonal viol repertoire listed with a description of the microtonal techniques used.

Two compositions, live electronic music for instrument and computer, have been analyzed in the essay to reflect one of my aesthetics principles, content-driven composition, and the solutions that the I have applied to solve the problems which have occurred in practice. By content-driven, I mean that compositional process, material, mood, and affect are expressions of content drawn from visual art, literature, nature, religion, traditional aesthetics and other non-musical sources. During the journey of exploration, I was often deeply moved and inspired by a historical moment, a real-world story, a film, a poem, a statement, an image, a piece of music, or a natural law. In content-driven works, these elements play a major role in the creative processes.
