The Dido myth has evolved and been adapted by many cultures over the centuries. Each Dido was altered to fit the needs of its creator, their society and customs. Despite these variations, every Dido retelling is derived from the Virgilian Dido, historical Dido, or chaste Dido narrative, or a combination of these stories. The pasticcio opera, Ópera armónica al estilo italiano que se intitula Dido y Eneas draws on the general Virgilian plot but emphasizes the chaste Dido narrative. The changes in the plot of Dido y Eneas reflect societal gender norms, theatrical conventions, and historical figures, specifically Queen María Luisa Gabriela, from eighteenth-century Spain. The Dido of Dido y Eneas can be divided into two main personas: Dido the queen and Dido the lover. Her arias, which come from preexisting Italian operas, convey the dramatic text very well. However, no matter what persona Dido portrays, she never fully loses control nor lets her passions rule her actions. Even in the moments before her suicide, her aria, "Punta intrepida," lacks the overt emotionality found in the popular Dido lament made famous by Purcell. This thesis aims to situate Dido y Eneas within the history of the Dido narrative and gender …

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.

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.

Often neglected in the musicological coverage of revolutionary music and theater, the Thermidorean Reaction phase (1794–1795) of the French Revolution was a period of governmental transition, in which Parisian theaters enjoyed the institutional and generic freedoms of the Le Chapelier Laws of 1791 in addition to relaxed enforcement of censorship. In recent years, Mark Darlow and Julia Doe's work has advanced understandings of operatic genres during the early years of the Revolution, which they characterize as a balance between "rupture and continuity" with artistic conventions of the ancien régime. I extend their methods of analysis to the second half of the revolutionary decade, exploring the impact that Thermidorian theatrical politics and legal (de)regulations had on operatic genre through the lens of Sapho (1794). This tragédie lyrique premiered at the Théatre de Louvois, a venue of ambiguous status within Paris's theatrical hierarchies. Featuring a libretto by Constance de Salm and music by Jean-Paul-Égide Martini, Sapho falls within the period of temporarily suspended theatrical privilege initiated by Le Chapelier and borrows key formal elements from "great" and popular operatic styles. The opera facilitates a discussion of how composers and librettists collaborated to navigate the rapidly shifting political and legal climate of Thermidor. …

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.

Heinrich Schenker's concept of the auxiliary cadence can be considered as a middleground manifestation of the Ursatz; his definition of the auxiliary cadence caters only to tonal compositions with a single background tonic, such as Brahms's songs. However, there exist compositions in which the a single background tonic cannot be easily ascertained. Such unorthodox compositions, in fact, can be found even prior to Brahms's songs. In such cases, although the opening and closing tonics are different and are often categorized as large-scale auxiliary cadence structured compositions, they do not operate within the single-tonic based tonal paradigm upon which Schenker formed his idea of the auxiliary cadence. Such compositions may be approached as a novel type of auxiliary cadence and described as "process-driven." The thesis presents and contrasts examples of both types of auxiliary cadences in songs by Schubert, Brahms, and Berg.
