TransFantasies is an interdisciplinary composition for Baroque flute (flauto traverso), computer music, and dance. A crucial component of the work is an interactive hardware and software environment that provides the opportunity for the players to shape aspects of the work during the performance. This essay discusses the influences that inspired the work and presents an in-depth analysis of notable elements of the composition. Primary issues include compositional models for gesture-based composition, historical performance practices, interactivity, and relationships between music and dance. The final component of the essay details the software component designed to create the composition. It also discusses music technology in current practice and its role in this particular work. At its core, TransFantasies is concerned with those moments where computer-influenced decisions and human behaviors collide.

This dissertation examines the role of noise in shaping the form of several recent musical compositions. This study demonstrates how the contrast of noisy sounds and harmonic sounds can impact the structure of compositions. Depending on context, however, the specific use and function of noise can vary substantially from one work to the next. The first portion of this paper describes methods for quantifying noise content using FFT analysis procedures. A number of tests on instrumental and synthetic sound sources are described in order to demonstrate how the analysis system may react to certain sounds. The second part of this document consists of several analyses of whole musical works. Works for acoustic instruments are examined first, followed by works for electronic media. During these analyses, it becomes clear that while the use of noise in each work is based largely upon context, some common patterns do exist across different works. The final portion of the paper examines an original work which was written with the function of noise specifically in mind. The original work is put through the same analysis procedures as works seen earlier in the paper, and some conclusions are drawn regarding both the possibilities and limitations of …

This dissertation describes a compositional model rooted in cross-influential methodology between complementary musical compositions that share generative source material. In their simultaneous construction, two composition pairs presented challenges that influenced and mediated the other's development with respect to timbre, transposition, pitch material, effects processing, and form. A working prototype first provides a model that is later developed. The first work Thema is for piano alone, and the companion piece Am3ht is for piano and live computer processing via the graphical programming environment Max/MSP. Compositional processes used in the prototype solidify the cross-influential model, demanding flexibility and a dialectic approach. Ideas set forth in the prototype are then explored through a second pair of compositions rooted in cross-influential methodology. The first work Lusmore is scored for solo contrabass and Max/MSP. The second composition Knockgrafton is scored for string orchestra. The flexibility of the cross-influential model is revealed more fully through a discussion of each work's musical development. The utility of the cross-influential compositional model is discussed, particularly within higher academia.

tA/v\Am (the Audio/Video Analysis Machine) is an interactive analysis engine optimized for audio/visual mediums, such as film, video games, and music. I designed tA/v\Am to allow users to pace the playback speed of videos containing sub-title style analytical text, without affecting the pitch content of the audio. The software affords writers the opportunity to display the relevant sensory data (i.e., analytical text and sound/visual media) more efficiently than the paper format. It also serves as a flexible medium; the writer may, for example, compress extensive text into a short amount of time, causing the reader to pause or slow down the rate of the video and thus suspending him/her in the sensorial moment which the writer describes. G®¡ND for Alto Saxophone, Percussion & Electronics is an exploration of the tipping point between signal and noise. Through tablature notation, MIR tools, granular synthesis, and the deconstruction of the saxophone, I have assembled a palette of inordinately contrasting sounds and threaded them together based on action profiles obtained by computer assisted analysis. With them, I have set varying physical conditions of friction that dictates whether the sonic energy is to become focused to one resonant point, or distributed equally/randomly throughout the spectrum …

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.

This paper discusses several compositions that use the computer screen to present music notation to performers. Three of these compositions, Law of Fives (2015), Polytera II (2016), and Terraformation (2016–17), employ strategies that allow the notation to change during the performance of the work as the product of composer-regulated algorithmic generation and performer interaction. New methodologies, implemented using Cycling74's Max software, facilitate performance of these works by allowing effective control of generation and on-screen display of notation; these include an application called VizScore, which delivers notation and conducts through it in real-time, and a development environment for real-time notation using the Bach extensions and graphical overlays around them. These tools support a concept of cartographic composition, in which a composer maps a range of potential behaviors that are mediated by human or algorithmic systems or some combination of the two. Notational variation in performance relies on computer algorithms that can both generate novel ideas and be subject to formal plans designed by the composer. This requires a broader discussion of the underlying algorithms and control mechanisms in the context of algorithmic art in general. Terraformation, for viola and computer, uses a model of the performer's physical actions to constrain the …

Ocean of Forms is a cycle of five songs for solo soprano voice and electronic/computer music accompaniment on poems by noted Bengali poet, musician, philosopher, and author Rabindranath Tagore. This work approaches the song cycle as a vehicle for expressing and highlighting the poet's words. Word and syllabic stress, text painting, melodic development, and formal structure all function in relation to the text and its meaning. the replacement of the traditional piano accompaniment with electronic accompaniment provides further possibilities for new timbral structures and transformations, expressive microtonal intonation, algorithmic and aleatoric formal structures, acousmatic and spatialized sound, and a broad sonic palette. This work strives to provide a more fully developed expression of the text as afforded by these expanded musical means. the critical essay primarily explores the interaction between text and music in the work. the first chapter explores the historical precedents for the genre of the song cycle and other texted music as well as specific influences on the work. the following chapters explore the connections between the text and the vocal line and electronic/computer music, respectively. the final chapter deals with the formal structure of the work, especially the justly-tuned harmonic scheme and its relation to the …

relent is a sacred work within the genre of interactive electronic music. the 20-minute composition is a multi-movement piece for four instrumentalists (saxophone, double bass, and two percussion) and computer that is inspired by the gospel message. relent is specifically about the gospel message that Christ died for man’s sins, rose from the dead, and through faith in him man can be reconciled to God. This project was an experiment in creating a work with a programmatic extramusical structure. in preparation for writing a piece based on Christian programmatic content, this paper presents an overview of research conducted on the intersection between art and Christianity referencing authors such as Harold Best, Nikolai Berdyaev, Hans Rookmaaker, Calvin Seerveld, Daniel Seidell, A. W. Tozer, Steve Turner, and Cornelius Van Til. This work was an experiment in trying to make very direct and specific musical ties to the narrative of the Gospel. Another highly experimental aspect of relent was in the way interactive electronics were used. Each acoustic instrument in the work has its own input and module within the Max patch, extending each acoustic instrument rather than adding an electronic accompaniment component. Additionally, non-traditional notation, both codified and real-time computer generated, improvisation, …

Dream of a Thousand Keys is a concerto for piano and orchestra, which consists of four movements presenting multiple dimensional meanings as suggested by the word "key." I trace the derivation of Korean traditional rhythmic cycles and numerical sequences, such as the Fibonacci series, that are used throughout the work, and explore the significant role of space between the soloist and piano that are emphasized in a theatrical aspect of the composition. The essay addresses the question of musical contrasts, similarities, and metamorphosis. Lastly, I cover terms and concepts of significant 21st-century compositional techniques that come into play in the analysis of this work.
