GranCloud is new application for the generation of real-time granular synthesis in the SuperCollider programming environment. Although the software was initially programmed for use in the interactive composition Creo, it was implemented as an independent program for use in any computer music project. GranCloud consists of a set of SuperCollider classes representing granular clouds and parameter objects defining control data for the synthesis. The software is very flexible, allowing users to create their own grain synthesis definitions and control parameters. Cloud objects encapsulate all of the control data and methods necessary to render virtually any type of granular synthesis. Parameter objects provide several simple methods for mapping grain parameters to complex changing data sets or to external data sources. GranCloud simplifies the complex task of generating granular synthesis, allowing composers to focus less on technological issues and more on musical considerations during the compositional process.

Watershed I/IV, for Solo Percussion and Real-time Computer Spatialization was composed in 1995 by Pulitzer prize-winning composer Roger Reynolds. This work is a 25-minute choreographed music drama for one multiple-percussionist, in which Reynolds incorporates the musical transformation of percussion instrument families, the physical gestures of the performer, and the spatialization of processed sounds around the audience. This dissertation addresses several aspects of Watershed, which include: the expressive intent and extra-musical concepts; the formal organization, and several non-musical tools that Reynolds utilized in designing the piece (e.g. logarithmically derived sequences); the primary musical motives; the instrument setup and how the resulting physical gestures contribute to the musical intent; and the real-time computer spatialization. Throughout the document, specific musical passages are demonstrated with notated musical examples and embedded video/audio clips. In addition, transcripts of my interviews with composer Roger Reynolds, percussionist Steven Schick (premiere performer of Watershed) and engineer/technician Greg Dixon (engineer for my performances of Watershed IV) are also included.

Playing‐related pain is a common and serious problem among pianists. Information on cause and prevention is extremely limited due to a lack of scientific research. The purpose of this study was to (1) review and describe risk factors for piano‐related pain among college students and piano teachers that were reported in my previous two research studies, (2) justify the use of an ergonomically modified keyboard as a potential solution for reducing playing‐related pain, and (3) test and evaluate the effectiveness of an ergonomically modified keyboard for alleviating pianists' pain. Both study populations reported high prevalence rates for playing‐related pain: 86 % for college students (n = 35), 91 % for piano teachers (n = 47). For both populations, statistical analyses confirmed that pianists with small physical size (hand size) were more prone to pain. This finding helped rationalize the use of an ergonomically modified keyboard (the key width is 1/16 narrower than the standard) for small‐handed pianists as an ergonomic intervention. To test the effectiveness of an ergonomically modified keyboard, 35 college students played identical music on both the reduced-sized keyboard and the standard keyboard. Observations of video‐recorded performances revealed that small-handed pianists can avoid extreme stretching of their hands …

Philip Glass' Glassworks (1981) is a six-movement composition for two flutes, two soprano saxophones/clarinets, two tenor saxophones/bass clarinets, two French horns, violas, cellos, and the DX7 electric piano. Glassworks consists of six movements titled "Opening," "Floe," "Island," "Rubric," "Facades," and "Closing." This thesis covers the first movement "Opening." Repetition in musical minimalism confronts traditional prescriptive codes of tonal music and post-tonal music. While challenging the traditional codes, repetition in musical minimalism established new codes for listening to minimal music. This thesis explores the implications of these ideas.

An examination of the historical treatises of Manuel Garcia II and Giambattista Mancini, scientific studies pertaining to glottal closure, and Vocal Function Exercises used in clinical speech pathology led to an exploratory study that attempted to increase the glottal closure in an untrained university male chorus using only choral voice building exercises. The exploratory study used a single group, pre-test post-test design, and data was recorded using audio recordings of the entire chorus as well as electroglottograph measurements of individual subjects. The data show an increase in glottal closure as measured by closed quotient values, and an increase in energy in the upper partials of the recorded acoustic signal from the chorus.

In 1993, American percussionist and composer B. Michael Williams published Four Solos for Frame Drums. This collection is considered the first work written exclusively for solo frame drum in Western notation. Williams primarily modeled his solos around traditional rhythms and techniques from Middle Eastern musical traditions as well as Glen Velez's virtuosic style of playing frame drums. He also drew influence from the music of South India and Sub-Saharan Africa. Williams intentionally combines the aforementioned elements as a means to expose his students and audience members to the music and drumming of these regions. The purpose of this paper is to provide a detailed analysis of select compositions for solo frame drum by B. Michael Williams in order to assist future performers in making well-informed interpretive decisions. The analysis will highlight the compositional style, structural components, technical demands and important performance considerations of four pieces by Williams: Quatrinity, Etude in Arabic Rhythms, Another New Riq and Rhythmic Journey no. 1: (From Conakry to Harare).

Rete Mirabile is my new installation piece combining scientific principles with live computer generated music. The title is a Latin term meaning "Wonderful Net," which I use to refer to the highly convoluted network of biological data that drives my installation. The sonification of data, computer modeling of biological processes, kinetic sculptures, and user interactivity are central parts of the installation. The paper is organized as follows: First, brief history of the forerunners that inspired my work is given. This includes a short discussion on how John Cage and David Tudor influenced current artists works, and how those works have influenced my own work. Then I review current installation works that share similarities with my own. Finally, a detailed discussion and analysis of the construction and function concludes the paper.

Ferruccio Busoni (1866-1924) has a firmly established reputation as one of the giant pianists of his age, yet his compositions are largely neglected both in musicological circles and on the concert stage. A better understanding of his thought processes might lead to a greater appreciation of his art, and the acknowledgement of his reverence for the music of Bach is an important key to such an understanding. Busoni's Fantasia nach Bach and Toccata, although two decidedly dissimilar compositions in terms of purpose and conception, represent two manifestations of Busoni's respect for Bach, whether it be in the form of assimilating Bach's compositions into one of his own, or by creating an original work to the same mold as some of Bach's works.

Luigi Nono's work Post-Prae-Ludium No.1 "per Donau" represents a model for the emerging genre of electroacoustic tuba music. It is important to preserve this electroacoustic work because of its value to the tuba literature. Not only is it one of the first electroacoustic works for the tuba, but it also was composed by a man who is highly regarded in the field of music composition. Its preservation will be difficult because of the rapid advancement in technology. Within the last three decades of existence, the technology has evolved three times. An examination of the performance practice in Post-Prae-Ludium was undertaken to understand the demand on the performer required to play this work. This study will look at both non-traditional performance practices, as well as an inherent problem of how the advancement of technology can actually threaten the survival of a work dependent upon a specific version of electronic technology. Nono worked in collaboration with Giancarlo Schiaffini to compose a work for tuba and live electronics. Correspondence with Schiaffini has provided his thoughts on the collaboration of Post-Prae-Ludium with Nono and given a better understanding of how to perform the work. Technology will change, and these current adaptations of Post-Prae-Ludium may …

Dan Beaty (1937-2002) was a prolific composer, pianist, researcher, educator, and writer. His large compositional output included chamber works, choral works, songs, orchestral pieces, electronic music, and keyboard works. Beaty was well versed in traditional Western music as well as the more avant-garde and perplexing idioms of the twentieth century. Beaty's compositions reflect the many fascinating, if not always popular, musical trends of his time. His music encompasses styles from serial to jazz, shows compositional influences from Arnold Schoenberg to Indonesian music, and demonstrates thought-provoking and highly intellectual craftsmanship. This document explores several of Beaty's songs through a discussion of the composer's life and compositional process. Songs included in this document are Three Weeks Songs, October, November, A Sappho Lyric, Love Song, That Night When Joy Began, and War Lyrics. This document was written to accompany the author's DMA Lecture-Recital at the University of North Texas. Unfortunately, Beaty's vocal music was never published and is mostly unknown. One goal of the project was to initiate interest in Beaty's songs. Through this document, Lecture-Recital, and additional performances, considerable strides have been made to bring Beaty's songs to new audiences throughout the United States. In addition, the author has received permission from …
