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.

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 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.

This paper uses the concept of mimesis to clarify the debate concerning the representation of reality in music. Specifically, this study defines the audio reality effect and the three main practices of realism as a way of understanding mimetic practices in multiple artistic media, in particular regarding the multimedia works of the "Landscape series." After addressing the historical debates concerning mimesis, this study develops a framework for the understanding of mimesis in sound by addressing the writings of Weiss, Baudrillard, Barthes, Deleuze, and Prendergast and by examining mimetic practices in 19th-century European painting and multimedia performance works. The audio reality effect is proposed as a meaningful translation of Roland Barthes' literary reality effect to the sonic realm. The main trends of realist practice are applied to electroacoustic music and soundscape composition using the works and writings of Emmerson, Truax, Wishart, Risset, Riddell, Smalley, Murray Schafer, Fischman, Young, and Field. Lastly, this study mimetically analyzes "2 seconds / b minor / wave" by Michael Pisaro and Taku Sugimoto and the works of the "Landscape series" in order to demonstrate the relevance of mimesis for understanding current musical practice.

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.
