The Replenishment cycle contains five works that allude to the experience of sleep, beginning with awake drowsiness and ending with the piece inspired by rapid eye movement (REM) sleep, titled Conceiving Realities. This last piece is an intermedia work composed for chamber ensemble, live painting with biofeedback, computer, and audiovisual processing. This critical essay describes the composition of Conceiving Realities within the context of the Replenishment cycle, followed by a thorough analysis of the research involved in the technological aspects of the piece, and finally, a description of the instrumentation, notation, intermedia elements, and technology comprising the work. Conceiving Realities uses a system of interactions between painting, biofeedback, music, and video, in which a painter wears brainwave and heartbeat sensors that send data to a computer patch processing the sound of an ensemble as the painter listens and creates the painting while responding to the music. This requires a passive biofeedback system in which the painter is focused on listening and painting. The computer uses the data to process existing sounds, instead of synthesizing new lines. The score blends elements of traditional notation, graphics, and guided improvisation; giving the performers some creative agency. This alludes to the way in which …

Fractus I is a composition for trumpet in C and live electronic sound. The electronics were primarily created using SuperCollider, an environment and programming language for real time audio synthesis. This project investigates SuperCollider's pattern and task functionality as a means of supporting and enriching the compositional process. Fractus I develops several different code architectures in order to randomize as well as synchronize various musical elements. The piece exploits SuperCollider as both an audio synthesis tool and a performance conduit. Additionally, the nature of SuperCollider's patterns and tasks influences the form and content of the composition. The project underscores SuperCollider as a powerful, versatile and open-ended tool for musical composition and examines future directions and improvements.

some soundwalks (Denton, TX) is an audio portrait of the Denton square - the area in downtown Denton bordered by the streets Oak, Hickory, Elm, and Locust. For three months (June - August, 2012), I went on soundwalks in this area, recording the soundscape and collecting material from each hour of the twenty-four hours of the day. The resulting work is presented as a layered montage of this gathered material that takes the listener on a twenty-four hour journey through the Denton square in about eighteen minutes. Ultimately, this sonic portrait of the Denton square is my subjective reaction to the daily soundscape of an area of Denton that embodies a strong sense of tradition combined with a newer presence of a growing population.

The purpose of this research was to explore historical perspective of brass music. There is a brief history of brass bands in Britain. Furthermore, the paper examines the differences between two brass band pieces in the repertoire, A Western Fanfare by Eric Ewazen and Brass Symphony by Jan Koetsier. Both of these pieces were compared and contrasted against the author's newly composed work for brass, Two Companion Pieces for Brass Ensemble. The paper covers different techniques commonly used in brass writing and points these techniques out in all three pieces.

Understatements for two-channel fixed media is a four-movement study of the sonic potential of acoustic instruments within the practice of electroacoustic studio composition. The musical identity of the entire composition is achieved through consistent approaches to disparate instrumental materials and a focused investigation of the relationships between the various acoustic timbres and their electroacoustic treatments. The analytical section of this paper builds on contemporary research in electroacoustic arts. The analysis of the work is preceded by a summary of theoretical and aesthetic approaches within electroacoustic composition and the introduction of primary criteria of sonic faktura (material essence) used in the compositional process. The analyses address the idiosyncratic use of the concept of faktura to contextualize and guide the unfolding of the work. The reconciliation of the illusory electronic textures and the acoustic sources that parented them may be considered the ultimate goal of Understatements.

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.

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

This paper presents a discussion of functional silence in contemporary classical music with a particular focus on the music of Salvatore Sciarrino and Jürg Frey, two composers whose drastically-contrasting bodies of work both occupy the interstitial space between the audible and inaudible. To begin, I address three main questions: what are the functions of silence in a musical context, how do the characteristics of a work affect our perception of these silences, and how do these functions relate to our perception of music on the edge of silence. In answering these first two questions, I discuss three categories of silence---temporal, spatial, and gestural---which I use in a silence-centric analyses of Sciarrino's Let me die before I wake, Allegoria della notte, and Infinito Nero, as well as Frey's Streichquarttet III. To further apply these concepts to music on the edge of silence, I provide a fourth category---timbral silence---which describes the perception of absence or silence within the presence of sound and allows for the application of existing functional principles of silence to sounding events. In turn, this allows us to understand the music of Sciarrino and Frey in terms of timbral completion and timbral dissolution, respectively. Having established a theoretical framework …

Act one of The Metamorphosis is based on the novella by Franza Kafka of the same title. In the writing of the act, George Benjamin's Into the Little Hill and Oliver Knussen's Where the Wild Things Are provide a model of using musical material as a storytelling device. Benjamin emphasizes the parallel nature of Crimp's text through the manipulation of similar music between the acts. Knussen uses form and color to emphasize Max's childlike energy and his desire to return home. In act one of The Metamorphosis these approaches are combined to enhance Kafka's absurd narrative through a rapid collage of texture and form that is influenced by both events and characters in the opera.

This Creature, Bride of Christ is a composition for soprano, alto flute, viola, marimba, and computer running custom software for live interactive performance in the Max/MSP environment. The work is a setting of excerpts from The Book of Margery Kempe, an early autobiographical manuscript depicting the life of a Christian mystic. The thesis discusses the historical, sociological, and musical context of the text and its musical setting; the use of borrowed materials from music of John Dunstable, Richard Wagner, and the tradition of change ringing; and the technologies used to realize the computer accompaniment. A score of the work is also included in the appendix.

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.

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.

Beginning in the 1970s, and aided by the advancement and an increased prevalence of computers, spectral music emerged as an important development in twentieth century music. Spectral composers, as exemplified by Gérard Grisey and Tristan Murail, took the harmonic spectra of sounds as the fundamental materials of composition. The resulting music placed an emphasis on texture and gradually evolving forms. The generation of composers immediately following the spectralists assimilated their techniques into distinct and varying styles. Finnish composer Kaija Saariaho uses spectral techniques to create an aesthetic that generates form and progression from a sound/noise axis. In her piece Du cristal…à la fumée, a number of pendulum and half-pendulum gestures build up texture and form. The accompanying original composition Axiom Unearthed employs similar pendulum gestures and uses spectral techniques to generate melody and harmony in an aesthetic divergent from traditional spectral pieces.

The ritual music written for the Compline service of the Liturgy of the Hours, Into Your Hands, is analyzed using an ontological and phenomenological approach, which seeks to answer how such sound/musical phenomena wed to the specific ritual dynamics of Compline in their own right can create a potential for encounter with the Divine. The Jewish philosopher Martin Buber’s understanding of encounter is used to show that the sound/musical phenomena in itself bears similarities with the nature of the Judeo/Christian God, and such a nature is revealed to be both irreducibly non-conceptual as well as an entity that establishes the ontological actuality of one’s being. Studies in the beginnings of humanity at large as well as the beginnings of the individual fetus reveal that an integrated expression of music and ritual can be said to have formed the impetus of such ontological beginnings through encounter. Therefore, one of the first sounds heard in the womb - that of water (or amniotic fluid) - constitutes what may be an archetypal sound of encounter. The phenomenological effects of such an archetype are analyzed in the music of Into Your Hands through topics such as the loss of aural perspective, immersion, dynamic swells, …

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.

Pleroma is a digital drama: a work composed of digital animation combined with electroacoustic music, presenting an original dramatic narrative. Pleroma's dramatic elements evoke both the classical form of tragedy and the concept of perceptual paradox. A structural overview of the drama and its characters and a plot synopsis are given to provide context for the critical discussion. Analytical descriptions of Beethoven's Coriolan Overture Op.62 and Mahler's Symphony No. 9 are provided to give background on tragic form and Platonic allegory in music. An investigation into the elements discussed in the analysis of the instrumental works reveals several layers of possible interpretation in Pleroma. Dramatic elements allow for tragic narratives to be constructed, but they are complemented by character associations formed by pitch relationships, stylistic juxtapositions, and instrumentation. A copy of the dramatic text is included to supplement the multimedia production.

This study engages the collaboration of dance and music, focusing primarily on experiences in the production of a large scale collaborative concert entitled Never Odd or Even. Famous historical collaborations offer archetypal collaborative models, the more unconventional of which are applied to the pieces of the concert. Issues and observations regarding cross-influence, project evolution, and application of the collaborative models are engaged to determine effective means of collaboration given different circumstances. The key focus of the study, the temporal relationship between music and dance, is explored in great detail to determine three models for relating time between music and dance. These temporal relationship models are applied to the pieces and evaluated on effectiveness and potential strengths when applied to dance.

Reference to a regular pulse is one of the most common ways of measuring time in music. As the basis for tempo, meter, subdivisions, and even formal symmetry, pulse, or the sonic articulation of regular units of time, is found throughout all levels of music. In this paper, I describe how I used a structure of twelve simultaneous pulses to compose "Monolith," a recent piece for MIDI piano, Pierrot ensemble, and fixed electronics. In the first chapter, I contextualize "Monolith" by briefly examining pulse's relationship to hierarchical structure in music and the possibilities for creativity in pulse-based hierarchical structures. In the second chapter, I analyze the use of pulse in Steve Reich's "Music for 18 Musicians," György Ligeti's "Self-portrait with Reich and Riley (with Chopin in the background), and Conlon Nancarrow's "Study No. 36 for Player Piano." In the third chapter, I describe in detail the relationship between the twelve-pulse structure and the various movements that comprise "Monolith," focusing on the relationship between compositional freedom and prescribed structure throughout the work.

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.

This document accompanies and explains the concepts used in the development of the composition, East is East, and West is West, (and Never the Twain Shall Meet). The process for generation and development of much of the musical content of the composition East is East, and West is West, (and Never the Twain Shall Meet) is the use of quoted musical materials. The second process, but equally as important, for development of the composition relies heavily on the idea of parallel development of modular ensembles and how the interactions created between them by sharing instrumentation can be a tool for development, as well as a challenge to the development of each module. Each module has an influence on at least one other module and is also influenced by at least one other module, creating a puzzle of interactions that must be navigated carefully when generating each individually. Both quotation and modularity are concepts employed by other composers, so this document also briefly explains how other composers have approached these concepts in their works in order to establish a historical relationship within the canon of western classical music to East is East, and West is West, (and Never the Twain Shall …

In the first half of the twentieth century, sporadic attempts of avant-garde composers to include sounds other than pitch in musical composition paved the way for the composers in the second half to embrace the sound of all types in their creative works. The development of technology since the mid-past century has facilitated composers' inclusive use of sound. The recent achievements in electronics and computers have led to cost-effective tools for today's composers to explore new possibilities in sound design and manipulation. Gradual for tenor saxophone and fixed electronics is primarily concerned with noise. Among the infinite possibilities of noise types, metallic sounds significantly contribute to the composition. The title of the piece refers to the compositional process in which the music progressively unfolds itself from the beginning to the end. The methods and strategies used to present the content give rise to a form I call accretion, described as an organic process by which the musical materials grow. Within the process, while established materials are interacting, combining, and forming layers, new materials may be incorporated and take part in the process. Throughout the composition, the interaction between sounds with common properties guides the music toward interactive unity, while the …

"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.
