In comparing oratorio traits across history, three aspects of oratorio were found to be particularly applicable to the creation of "Deborah: A Chamber Oratorio in One Act." These aspects were: the selection of topic and the creation or adaptation of text; the differences between recitative and aria, in form and function; and the level of stylistic diversity within a given work.

"Natural Disasters" is a cycle of five extractable movements for septet, conductor and computer. Each movement in the cycle is inspired by the ways that humans are affected by and respond to five different classes or categories of natural disasters: meteorological, such as hurricanes, tornados, and haboobs; geological, like earthquakes and landslides; hydrological, including flooding and sea level rise; wildfires; and extra-planetary disasters such as meteors and solar flares. The disaster types are used as overarching themes and also as sources for the organization of the movements and their surface details. This paper presents an overview of the conception and organization of cycle, the themes addressed in each movement and the compositional techniques used. The history of composers using weather or disaster-related themes in prior music is reviewed, and a survey of contemporary disaster-related compositions is presented.

This paper presents the history and the theoretical study of mixed music and focuses on two piano solo works and two mixed electroacoustic compositions for piano and electronics. By discussing the working process and giving the analysis of the original composition Alchemy for piano and electronics, this paper investigates the relationship between cause, source and spectromorphology, reflecting how the concept of energy-motion trajectory are embodied in this mixed electroacoustic work. Alchemy is a mixed composition for piano solo and 8-channel fixed electronics focusing on the gestural play and sonic expression. The live piano part explores the gestural sound played with a slide (cup), paper clip, and objects placed inside the piano. The 8-channel electronics part is mainly derived from the recorded acoustic piano. It extends the sonic potential of source materials and presents the diverse vectorial movements of spatialization.

In this thesis, I demonstrate how I use leitmotif in a programmatic context in my original orchestral suite, The Legend of Two Rings.

Metaphor and Mimesis in an Animal Soundscape serves as a supplementary document for two pieces of contemporary concert music; HOWL, for viola, saxophone and fixed media, and Pastorale for viola and fixed media. Both works quote the second movement of Antonio Vivaldi's violin concerto, La Primavera. This quotation is used to support a musical program which explores the larger topic of metaphor in music. In addition, both pieces play with contemporary trends in music including, but not limited to, acoustic ecology and spectralism.

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.

Astronomy and music are both fundamental to cultural identity in the form of various musical styles and calendrical systems. However, since both are governed by incontrovertible laws of physics and therefore precede cultural interpretation, they are potentially useful for insight into the common ground of a shared humanity. This paper discusses three compositions inspired by different aspects of astronomy: Solstitium e Equinoctium, a site-specific composition for four voices and metal pipes involving an inclusive communal musical ritual and sonic meditation; Helios, a short symphonic work inspired by helioseismology; and Perspectives, a piece for soprano and percussion based on a logarithmic map of the universe.

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.

Rainpiece is a composition for flute, viola, harp, and computer, cyclic and open in form, and inviting collaborative improvisation by instrumentalists and computer operator together. It is also a study of water, from torrential downpours and bubbling springs to rivers and waterfalls. The movement of water through the phases of the water cycle is the central metaphor guiding the cyclic and theoretically endless structure of the work. Rainpiece is also a model of community, collaboration, and above all mindful meditation. The metaphor of water is one that focuses the mind, and brings together the community of performers and audience members into a context with which all can connect emotionally. Like the sound of flowing water (which is included in the piece in the form of processed field recordings), the musical ideas of Rainpiece are constantly changing, and yet continually recurring and returning; this connects with concepts of meditation and mantra as well. The work proposes a new direction in interactive chamber music that integrates natural and composed sound worlds, with the goal of shaping a social and acoustic environment that allows for openness, mindfulness, and connection.

This paper provides an overview of the inspiration, research, and creative process involved in the composition of EverWind for orchestra and electronics. EverWind is based on field recordings from the American Southwest. The composition uses pitch material derived from spectral analysis of the recordings, and it incorporates a fixed media element using the field recordings that are then electronically manipulated to various degrees; this fixed media element is played alongside the orchestra. The paper also analyzes John Luther Adams' Dark Waves for Orchestra and Electronics and R. Murray Schafer's Music for Wilderness Lake in order to place EverWind within the broader musical context.

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.

This paper explores various technologies available to the modern composer and utilized in recent modern opera, providing creative approaches to producing aural, visual, and theatrical performance environments. It also explores my own use of digital technology in Transient Delete. Transient Delete is a digital miniature-opera that explores different aspects of a community of post-human cyborgs. The story follows Iméra, a newly converted cyborg as she acclimates herself to this new cybernetic existence. During this process she meets several other cybernetic entities that are there to help guide her through her metamorphosis.

Forgotten Lyres is a musical response to Percy Bysshe Shelley's poem Mutability, which depicts the fragility and unpredictable nature of human life. Four independent chamber ensembles make up the performing forces of Forgotten Lyres; the musicians evoke the topics of Shelley's text as they interact and coordinate with one another according to a variety of paradigms and without the use of a conductor. This essay focuses on the approaches to coordination within and between ensembles, and the ways in which the musicians' interactions can evoke and convey Shelley's texts. The essay also examines works by Mel Powell, Toru Takemitsu, Witold Lutoslawski, and Pierre Boulez as examples and precursors for the coordination strategies employed in Forgotten Lyres.

This dissertation explores the analysis and creation of compositions from the standpoint of texture and momentum. It is comprised of four chapters. The first presents a number of concepts as tools for analysis, including textural typography and transformation, perception of time and psychological engagement of an audience, and respiration as a metaphor for musical momentum. The second and third chapters apply these tools to Gerard Grisey's "Periodes" and "Partiels," and Brian Ferneyhough's "Lemma-Icon-Epigram." The fourth explores specific methodologies used in composing my dissertation piece, "Phase," including the application of number systems ranging from formal to local levels.

My recent compositions are situated within a postmodern theoretical framework. The heterogeneity of materials and hybridity of musical formation in these works are interpreted and contextualized within a personal reading of postmodern theories. The critical essay traces my aesthetics through a historical investigation into the definition of musical postmodernism. Through extensive citation and analysis of the writings of Julius T. Fraser, Italo Calvino, and Richard Rorty, the essay aims to provide a theoretical context for the interpretation of the musical examples. The creative documentation contains three newly-composed musical works: Piano Trio from Opus 3/c, Opus 6 for Violin, and Opus 7 for Piccolo. The works' postmodern features include creative approaches to the fragmentation of musical time into separate levels, historical allusions, and the exploration of multiplicity.

Creativity is not a hierarchical, but an intertextual, rhizomic process, pulling from a vast array of interests, experiences, and influences. These feed into each other, to inform and motivate artists as creating persons in an ongoing process we call the creative act. Anytime an artist sets out to make something, they are experiencing a dynamic yet concentrated moment of energy in the chaotic cloud of creativity. To demonstrate this, I explore several ideas that inform my piece, Codex Symphonia, including musical influences, but also visual art, film, literature, philosophy, social theory, and politics. In this document, I show that the act of creating a musical work is a deeply personal process that relies heavily on the experiences and vast network of influences on the composer. With this document I look to the contextual structure(s) that point to the possibilities that a work might exist. That is to say that the composition Codex Symphonia is a specific result of an extensive network of ideas and influences not coming from a single origin—it is, in fact all of them together at the same time in a metamodernist act of reconciliation.

Audiovisual concatenative synthesis is an analysis-driven granular technique using a corpus of multimedia data to sequence audio and video streams on a microtemporal level. This text outlines my development of this technique as a tool for multimedia composition, using my work, Replica, as a case study. The paper illustrates how the concepts of granular structure, gesture capture, and replication are integral not only to the software but to the architecture of the composition. In doing so, machine learning approaches to music and visual art are reviewed and related to my personal compositional practice. Additionally, I attempt to show how audiovisual concatenative synthesis provides a composer with strategies for shaping one's sense of time through disorienting audiovisual cues and tightly organized counterpoint between sound and image, stage and screen, and the real and virtual.

This dissertation investigates the process of collaboration and the application of both notational and technological schemes to integrate elements of contemporary composition and tap dance as a consolidated art form. Overall, this document gives an overview of choreographer/composer collaborations in Western classical music; movement notation; and ultimately analyzes my original music—a live set for tap dancer, live musicians and electronics—entitled Digital Tap Dance. Altogether, this project represents the culmination of music and dance as a compelling intermedia collaboration. By (1) researching different practices of composer-choreographer collaborations, (2) notating rudiments for tap dance, (3) creating software for tap dancers, and (4) composing original music for tap dancers, this dissertation will create options for composers and choreographers alike in composition and improvisation.

Loose Id, scored for orchestra (piccolo, 2 flutes, 2 oboes, 2 clarinets in B-flat, B-flat contrabass clarinet, 2 bassoons, contrabassoon, 4 horns in F, 3 trumpets in B-flat, 2 trombones, 1 bass trombone, tuba, timpani, percussion (3 parts), violin I, violin II, viola, violoncello, and contrabass), is an abstract realization in sound of the energy of the Id. Unleashed, without the counterbalance of Ego or Superego, the Id generates unbridled instinctual energy, resulting in an orgiastic frenzy. Distinct from a state of dementia, this piece represents a thoroughly lucid and intentional rampage of self-indulgence. The accompanying essay examines the underlying structural principles of Loose Id, focusing on how they aid the creation of the overall experience of the piece. Particular attention is given to the concepts of linearity and nonlinearity and their roles in different levels of creative and listening processes.

Making Sense of Things is a piece composed through consideration of the relationship between music, meaning, and materiality. The piece, written for voice, flute, percussion, and live electronics, explores topics of the "sensible" and "nonsensical" in music, moving through a variety of sonic episodes that feature different notational approaches, electronic textures, technical instrumental practice, and theatrical elements in order to explore a variety of expressive possibilities while unified around the central musical ideas of scratching sounds and metal bars. The critical essay examines the relationship between the piece and the theoretical writings which inspired it. Reading through the work of Gilles Deleuze and Félix Guattari, I examine the relationship between Making Sense of Things and new materialist discourses, affect theory, and semiotics.

This thesis explores collage music's formal elements in an attempt to better understand its various themes and apply them in a workable format. I explore the work of John Zorn; how time is perceived in acoustic collage music and the concept of "super tempo"; musical quotation and appropriation in acoustic collage music; the definition of acoustic collage music in relation to other acoustic collage works; and musical montages addressing the works of Charles Ives, Lucciano Berio, George Rochberg, and DJ Orange. The last part of this paper discusses the compositional process used in the works Tempered Confetti and Venni, Viddi, – and how all issues of composing acoustic collage music are addressed therein.

"Compositional Approaches to New Media Paradigms" is the discursive accompaniment to the original composition BoMoH, (a new media chamber opera. A variety of new media concepts and practices are discussed in relation to their use as a contemporary compositional methodology for computer musicians and digital content producers. This paper aligns relevant discourse with a variety of concepts as they influence and affect the compositional process. This paper does not propose a new working method; rather it draws attention to a contemporary interdisciplinary practice that facilitates new possibilities for engagement and aesthetics in digital art/music. Finally, in demonstrating a selection of the design principals, from a variety of new media theories of interest, in compositional structure and concept, it is my hope to provide composers and computer musicians with a tested resource that will function as a helpful set of working guidelines for producing new media enabled art, sonic or otherwise.

This paper presents an overview of the concepts and strategies in the original composition, The Harbour of Incense, a cycle of three movements for different groups of instruments. Each movement addresses an aspect of the musical cultures of Hong Kong. The first movement Taan Go for Harp Solo explores the sound world of the folk genre saltwater song; the second movement Jat1 Wun2 Sai3 Ngau4 Naam5 Min6 for Flute and Piano highlights the musicality of Cantonese language; the third movement Daa Zaai for Oboe, Clarinet in B-flat, Bassoon, and Percussion, is inspired by the keyi music used in the Taoist funeral. The paper discusses how to bring together Southeast Asian aesthetics and contemporary Western compositional techniques, as well as how to communicate this unique cultural experience to performers and audiences from other backgrounds. It provides the transcriptions of two saltwater songs and an excerpt of keyi music, and illustrate how they inform the structures, textures, and melodic gestures of the composition. The nine tones of Cantonese language are also explored for generating melodic materials, metric plans, and articulation writing.

Virtual Stage is a project to use Virtual Reality (VR) technology as an audiovisual performance interface. The depth of control, modularity of design, and user immersion aim to solve some of the representational problems in interactive audiovisual art and the control problems in digital musical instruments. Creating feedback between interaction and perception, the VR environment references the viewer's behavioral intuition developed in the real world, facilitating clarity in the understanding of artistic representation. The critical essay discusses of interactive behavior, game mechanics, interface implementations, and technical developments to express the structures and performance possibilities. This discussion uses Virtual Stage as an example with specific aesthetic and technical solutions, but addresses archetypal concerns in interactive audiovisual art. The creative documentation lists the interactive functions present in Virtual Stage as well as code reproductions of selected technical solutions. The included code excerpts document novel approaches to virtual reality implementation and acoustic physical modeling of musical instruments.
