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.

And Drops of Rain Fall Like Tears is a composition for electroacoustic music with an optional ambient video component. The composition consists of a single movement electroacoustic work twenty-two minutes in duration. The piece creates an immersive sonic environment within the confines of a typical concert space, thereby recreating the powerful temper and subtle beauty of nature from different sonic perspectives. The paper is divided into four chapters, each discussing an element of the piece in detail. The introduction presents background information and compositional approach for the composition. Chapters 1 through 4 present detailed information related to the creation of both the electroacoustic music and video elements of the piece. Chapter 4 contains relevant information to the performance of the piece.

Augeries is a multi-channel electro-acoustic composition for flute, clarinet, percussion, and tape. It is intended to be diffused through an 8-channnel playback system. Inspired by the first four lines of William Blake's Augeries of Innocence, Augeries captures the qualitative aspects of Blake's poetry by presenting the listener with an equally aperspectival aesthetic experience. The small-scale structure reflected on the large-scale form - the infusion of vastness and expansiveness into the fragile and minute. Augeries incorporates techniques of expansion and contraction, metonymic relationships, dilation and infolding of time, and structured improvisation to create an experience that is designed to explore the notion of musical time, and to bring to the listener the sense of time freedom. The critical analysis suggests that the increase in the notions of musical time, the aesthetics with which they conform, and the new time forms created, encapsulate communicative significance. This significance exists within a horizon of meaning. Semiotics illuminates an understanding of the structuring techniques used to render time as an area of artistic play. Understanding the aesthetics and mechanisms through which these techniques can be used constitutes a shared horizon of meaning. The concepts of cultural phenomenologist Jean Gebser, as explicated in The Ever-Present Origin, …

I, Blavatsky is a one-act opera based on the life of Helena Petrovna Blavatsky, a nineteenth-century Russian princess and co-founder of a religious organization called the Theosophical Society. The libretto, by the composer, involves a cast of three principal soloists and minor roles for six more singers who are also participants in a small chorus. The text format features free verse alternating with regular, rhymed strophes. Accompaniment is provided by a piano. Melodic structure combines some nineteenth-century Romantic idioms with twentieth-century style. Most of the melodic and harmonic material was intuitively composed to express the text. Rhythmic and stylistic contrasts are accomplished in the representation of the extensive travels of the main character. Stage directions involve a stylized set, several scenes requiring minimal set changes, magical effects to represent that facet of Blavatsky's life, and onstage costume changes for several characters. Approximate duration is one hour.

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.

Cēgə Trouhèst is a three-movement work of about thirteen minutes duration. The text by the composer provides a vehicle for aural stimulation only. Cēgə Trouhèst is a continuum of resonances embellished by melodic and rhythmic passages. These embellishments along with other devices and the choice of instrumentation all contribute to the development of the varied timbres. The first two movements introduce the material to be employed in the third, which continues the idea of change exhibited in the text by modification and extraction. Timbre is the most important aspect of this work. It is exploited homophonically, contrapuntally, and through instrumental/vocal interchange and timbre modification of a single tone.

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 …

Based on a story by Joshua Forehand with additional lyrics by Joshua Bradford, Clockwork Plums is an original musical work that integrates techniques and ideas from composers and different cultures. The accompanying essay about the work includes a summary of the story, "Clockwork Plums," some historical background covering 30 years of pop music, an analysis focusing on the use of African and Reichian compositional devices, and discussion about controlled improvisation and use of the voice as compositional tools. The music consists of three sections scored for 5 voices (lead male vocalist and SATB), flute (doubling tenor saxophone), Bb clarinet (doubling baritone saxophone), violin, cello, piano, electronic keyboard, electric guitar, electric bass, drum set, and percussion.

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.

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.

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.

Explorations is a three-movement experimental work for eighteen-piece jazz ensemble consisting of the following instruments: soprano saxophone, alto saxophone, two tenor saxophones, baritone saxophone, two trumpets, two flugelhorns, three trombones, bass trombone, electric guitar, vibraphone, contrabass, drums and piano. The duration of the work will approximate twelve minutes. The first movement features geometric configurations of spatially notated sound which emphasize percussive qualities of the ensemble (i.e. key clicks, tongue slaps, mouthpiece pops, etc.). Tone clusters of various pitch, texture and dynamics derived from blues scales provide the source material for the second movement. A slowly developing dynamic counterpoint creates the sound mass texture and delineates the form. Movement Three features a contrapuntal poly-metric collage of variations on a four-note theme. The collage provides the background fabric for an exchange of periodic and aperiodic events.

"Eyre" is a composition of approximately sixteen minutes duration for an instrumental ensemble consisting of two flutes, oboe, B𝄭 clarinet, bassoon, guitar, and cello. It is inspired by a large seasonal lake basin in South Australia of the same name. The piece is divided into three movements; the first is fast and quasi sonata-allegro form without the recapitulation; the second is slow and through-composed; and the third, essentially the missing recapitulation from the first movement. Much of the motivic material for the piece is derived from the initial progression of triads. Harmonic and melodic development of this material contains some modal tendencies. While the overall effect tends toward equal weighting of the instrumental forces, there is some featuring of the guitar and an interplay between the woodwind and string instruments.

For Unto Us is a one movement work for soprano and orchestra. The text, by the composer, describes the thoughts and feelings of Mary, the mother of Jesus, as she watches the crucifixion. Mary's process of faith is traced through the sequence of dramatic events which proceed and follow the crucifixion. The work explores symbolic instrumentation, juxtaposition of harmonic languages, and extended techniques for performance and notation. The setting of the text combines traditional operatic idioms with new elements in the music. The duration of this dramatic, quasi-operatic scene is approximately nine minutes.

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.

My composition, Estruendos, is a work for large symphonic orchestra, guitar and computer-generated and processed sounds on CD. The work lasts 23 minutes and 45 seconds. My dissertation is composed of two parts: Part One comprises the analysis and Part Two comprises the score. Part One gives a brief background of my compositional dialect and aesthetics. It also includes a discussion of the compositional process and general overview of Estruendos. In addition, it illustrates the primary role the placement of sonic events in time and timbral structure play in the pathos of Estruendos.

Heart of the Fathers is a programmatic, seven movement work for wind symphony depicting my ancestors and their role as part of the history of The Church of Jesus Christ of Latter-day Saints. The movements represent their spiritual experiences, labors, times of joy, persecution, migration, and finally their arrival and success in their new homeland. The piece is organized in seven movements. Each movement represents a different portion of history leading to the western migration of my ancestors. The programmatic music contains a variety of symbols depicting the experiences of the pioneers. In the paper, each chapter addresses an individual movement. For each movement, the following information is provided: the historical events that inspired the piece, the musical symbols that characterize the program, and an analysis of the function of the music.

The poetry of Sumer, inscribed in cuneiform script on clay tablets dating from 2000 B.C., is considered humanity's earliest written literature. Hymns To Inanna is a three-movement, mixed media work based on adapted English translations from ancient Sumerian text. The text is sung by SATB choir and musically illustrated by harp, flutes, percussion, and computer-generated sound (on tape). My musical setting displays these hymns not as a reflection of antiquity but as a timeless expression of spiritual thought. Certain elements of the composition evoke associations with early culture and music. These components, however, are transformed or merged with musical characteristics of other eras, idioms, and forms thus representing a conceptual and stylistic "bridge" between past, present, and future.

The dissertation is recorded computer music. It has a duration of fourteen minutes and fifty seven seconds. The source sound material is a reading of a sonnet of the same name by thirteenth century Sienese poet Cecco Angiolieri. It utilizes Linear Predictive Coding and Short-time-fourier synthesis in addition to postprocessing by spatialization and digital filtering. The discussion of the piece includes an explanation of the synthesis techniques, the pitch manipulation algorithms and the programs written by the composer to generate computer scores based on these algorithms, and finally how the individual musical events were generated and mixed together. The computer scores and programs used to generated these scores are provided after the discussion.

Iconographs is such a composition in which mathematical techniques are brought to bear. Nine separate number series have been generated and carried out to 1024 units. These series are combined by addition to calculate a single number by taking the remainder after dividing the sum of the series by nine. This mod 9 reduction is used to choose a set of pitches. Iconographs is a composition for microcomputer and chamber orchestra written in proportional notation with 1024 time segments grouped into 32 pages of 32 time segments each. The duration for each segment is .618034 seconds, which is the Golden Mean of one second, represented in a horizontal space of .34375 inches. The horizontal space/time-frame proportion is consistent but the actual duration of sounds are only approximate. The duration of the entire composition is 10.54778 minutes with a total horizontal space of 352 inches. The structure of the composition as a whole has no relationship to any of the traditional forms does contain a focus of formal structure at time-frame number 632, the Golden Mean. This focus is expressed by a density of sound events in all parts.

Images of Remembered Earth is a musical composition scored for full orchestra. The composition was inspired by Georgia O'Keeffe's painting, Light Coming on the Plains I (1917), which depicts a sunrise over a flat and empty landscape. In the painting, the expanse of the sun's rays is expressed through an even-blended transformation of color from goldish-blue at the light's source to progressively darker shades of blue near the edges of the canvas. The progression of color is interrupted by thin gold bands which sectionalize the sunrise into seven concentric arches. The construction of the musical composition derives musical materials directly from elements found within O'Keeffe's painting, specifically the shaping of structure, expansion, and color in arch patterns. Arch patterns, an integral element in O'Keeffe's painting, govern elements in the musical composition, including pitch selection, the overall tempo scheme, rhythmic activity, and formal shape. Pitch materials are expansive by design; this expansive quality is exhibited through the employment of wedge-shaped musical ideas and through the utilization of higher and lower registers. O'Keeffe's use of color in the painting influenced the orchestration of the music and is manifested in two ways: 1) gradual transformation of timbral colors and 2) the juxtaposition of …

jn4.gesture is an interactive multimedia composition for dancer and computer designed to extend the possibilities of artistic expression through the use of contemporary technology. The software produces the audiovisual materials, which are controlled by the movement of the dancer on a custom rug sensor. The software that produces the graphic and sonic material is created using a modular design. During run-time, the software's modules are directed by a scripting language developed to control and adjust the audiovisual production through time. The visual material provides the only illumination of the performer, and the projections follow the performer's movements. The human form is isolated in darkness and it remains the focal point in the visual environment. These same movements are used to create the sonic material and control the diffusion of sound in an eight channel sound system. The video recording of the performance was made on April 22, 2002. The work was produced in a specialized performance space using two computer projectors and a state of the art sound system. Arleen Sugano designed the costumes, choreographed and performed the composition in the Merrill Ellis Intermedia Theatre (MEIT) at the University of North Texas. The paper focuses on the design of the …

For a composer of today, the relationship between new music and music from many centuries past remains problematic. In order to create something new, it is necessary to go beyond previous techniques of composition in some way. At the same time, new music that has no connection with music of the past runs the risk of irrelevance. Just tuning offers one possibility for reconciling this problem. By effectively warping music of the past through the lens of altered tuning and contemporary composition techniques, music of the past may be understood in previously unknown ways. Part I, the critical essay, presents historical background and analysis of a cycle of three works in altered/just tuning. Part II presents scores of the works.

The Latin Mass is a musical composition in five movements, scored for large choir, standard orchestra, and two soloists. The movements are the standard parts of the Roman Catholic Mass Ordinary. The language is set mainly in Latin with two exceptions: the Kyrie movement is set in Greek (which is the standard Roman Catholic setting), and the Credo is simultaneously recited in English and sung in Latin. The work is scored using conventional notation techniques and employs rather conservative technical demands on both the choir and orchestra. No extended techniques are required of any of the performers. It is set in a modal harmonic language.
