Symphony No. 1 is an orchestral composition for twenty-four instrumental groups without percussion instruments. It was composed with Algorithmic Composition System software, which gives driving forces for composition to the composer through the diverse compositional methods largely based on physical phenomena. The symphony consists of three movements. It lasts about sixteen minutes and twenty-six seconds--five minutes and twenty-two seconds for the first movement, five minutes and forty seconds for the second movement, five minutes and twenty-four seconds for the third movement. Most musical components in the first movement of the symphony are considered embryos, which gradually begin developing through the second and third movements.

In Nomine Domini is an eighteen-minute composition for two chamber orchestras with two soloists using real-time interactive signal processing techniques. The first chamber orchestra is scored for flute (piccolo), English horn, trumpet in C, trombone, two percussionists (cowbells, wood blocks, tenor drum, suspended cymbal, gongs, tam-tam, temple blocks, tambourine, snare drum, timbales, and bass drum), horn in F (soloist), viola, and string bass. The second chamber orchestra is scored for oboe, clarinet in Bb (bass clarinet in Bb), bassoon, tuba, two percussionists (crotales, two marimbas, vibraphone, chimes, and tom-toms), piano (soloist), violin, and cello. Real-time interactive signal processing techniques are achieved through the use of a stereo multiple-effects signal processor and a personal computer running MIDI interactive software. The work is based upon the four-hundred and seventy-five year old in nomine composition tradition begun by John Taverner in the Benedictus of his Mass Gloria tibi Trinitas (1520) and continued in over one-hundred and fifty Renaissance settings. In Nomine Domini consists of three movements: "Taverner* derived from the Benedictus of the Mass Gloria tibi Trinitas (1520), "Byrd" derived from the Benedictus of William Byrd's Five-voice Mass (1592), and "Tye" derived from Christopher lye's In Nomine XIII "Trust" (1578). In Nomine Domini …

Matador is an opera scored for orchestra, mixed chorus and soloists (mezzosoprano, 3 tenors, 2 baritones). The work is in one act divided into two main sections. Each of these sections is divided into subsections. The libretto is aphoristic in nature and dictates the form of each of these subsections. The division into two parts also serves as a means to evoke a sense of hopelessness of emotions in the first and a transforming disposition that culminates in a jubilant song in the second.

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 contains five chapters: 1. Introduction, 2. Basic Digital Processing Used in Summer Rain, 3. Part I Summer Rain - Dawn, 4. Part II After the Summer Rain and 5. Conclusion. Introduction contains a brief historical background of musique concrète, Electronische Musik, acousmatic music and music for instruments and tape, followed by basic descriptions of digital technique used in both parts of Summer Rain in Chapter 2. Also Chapter 2 describes software used in Summer Rain including "Kawamoto's VST," which is based on MAX/MSP, to create new sounds from the recorded samples using a Macintosh computer. In both Chapter 3 and 4, Kawamoto discusses a great deal of the pre-compositional stage of each piece including inspirational sources, especially Rainer Maria Rilke's poems and Olidon Redon's paintings, as well as her visual and sound imageries. In addition Chapter 3 she talks about sound sources, pitch, form and soundscape. Chapter 4 contains analysis on pitch in the piano part, rhythm, form and the general performance practice. Chapter 5 is a short conclusion of her aesthetics regarding Summer Rain, which is connected to literature, visual art and her Japanese cultural background.

La Primavera: Concertino for English Horn and Chamber Orchestra is a work in a traditional chamber orchestra instrumentation: single woodwinds (flute, oboe, clarinet, and bassoon), two French horns, trumpet, timpani and strings. A through-composed work of 14 minutes in duration, the Concertino is conceptually based on the idea that spring is not the first of the seasons, but rather the last. As a result, all of its motivic materials are organically linked to one another, and function as paired forces that struggle for supremacy. The introduction of the third motive functions as a motivic synthesis, since it contains intrinsic elements of previous motives. There are several important compositions based on the topic of the seasons among them we find: Vivaldi's Concerto Grosso Le Quatro Staggione, Haydn's oratorio The Seasons, and Piazzola's chamber work Las Estaciones. While researching this topic, the conceptual dilemma of spring as the last season was considered. This became a turning point in the compositional process strong enough to consider the spring as a singular topic of interest. The analysis of this work through Derrida's Deconstruction theory first came to me while reading Rose Rosengerd Subotnick's Deconstructive Variations: Music and Reason in Western Society. The Linguistic approach, …

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.

Soar! is a musical composition written for wind ensemble and computer music. The total duration of the work is approximately 10 minutes. Flocking behavior of migratory birds serves as the most prominent influence on the imagery and local structure of the composition. The cyclical nature of the birds' journey inspires palindromic designs in the temporal domain. Aesthetically, Soar! portrays the fluid shapes of the flocks with numerous grains in the sounds. This effect is achieved by giving individual parts high degree of independence, especially in regards to rhythm. Technically, Soar! explores various interactions among instrumental lines in a wind ensemble, constructs overarching symmetrical structures, and integrates a large ensemble with computer music. The conductor acts as the leader at several improvisational moments in Soar! The use of conductor-initiated musical events in the piece can be traced back through the historic lineage of aleatoric compositions since the middle of the twentieth century. [Score is on p. 54-92.]

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 …

In the composition Archetypal Dreams, musical imagery is created through motifs and ideas that represent the symbolic messages of the unconscious. These motifs are introduced, developed, transformed, and overlapped in contrapuntal dialogue. This unfolding of material grows in significance and complexity building to a resolution of tension. The relationship of motifs to the row is re-established and the row is reconstructed. In this manner the conscious and unconscious elements of the personality are symbolically reconciled. The four movements of the work are entitled: I. Primordial Images; II. Archaic Remnants; III. Mythological Motifs; IV. The Process of Individuation

Night of Glass is for chamber orchestra with an estimated performance time of 14 minutes. The instrumentation for the work, using one player per part, is Flute (also small glass wind chimes), Oboe (also 1 tuned water crystal), Clarinet in A (also small glass wind chimes), Bassoon (also 1 tuned water crystal), Horn in F (also 1 tuned water crystal), Trumpet in C (also 2 tuned water crystals), Percussion (Vibraphone, Glockenspiel, Chimes, Bell Tree, Hammered Dulcimer, 3 Suspended Cymbals, 1 Large Tam-tam, 4 Roto Toms, 3 Tympani), Piano, 1st Violin, 2nd Violin, Viola, Cello, and Double Bass, While not programmatic, the work is divided into six sections each expressing a predetermined emotional content: fragility, anxiety, solitude, fear, catharsis, and reconciliation. All are emotional contents which are found in the dream-state that is reflected in the work's title. All aspects of Night of Glass (i.e., pitch material, form structure, and structural density) are centered around the unifying factor of emotional projection within each section. The work seeks emotional content through the expansion of composition procedures while being accessible to listeners.

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.

Symphony No. 1 "Concertante" is a work of approximately twenty-two minutes duration for chamber orchestra. The work is scored for flute (doubling piccolo), oboe (doubling English horn), B-flat clarinet, bassoon, trumpet, F horn, trombone, tuba, percussion, harp, piano (doubling celesta), solo violin, solo viola, solo cello, solo double bass, and strings.The percussion battery, which is to be played by one performer, includes three timpani, vibraphone, orchestra bells, xylophone, chimes, suspended cymbal, bass drum, snare drum, and two triangles. One group of instruments, including the eight winds, percussion, and the four solo strings, is treated primarily in a soloistic manner although it also functions as a part of the ensemble. The remaining group, piano, harp, and strings, functions primarily as an accompanying group although it does get some soloistic treatment. The work is in four movements, each of which uses the traditional symphonic form. Movement I is in sonata-allegro form, movement II a simple ternary "song" form, movement III a scherzo and trio, and the final movement is a theme and variations. These traditional forms apply only to thematic use and development, however, for the tonal scheme is developed in a broader design which unfolds throughout the course of the four …

Vox Organalis is a concerto for organ and orchestra. It employs an ensemble comprising the compliment of wind, percussion, and string instruments normally available within a contemporary symphony orchestra with augmented brass and woodwind sections. It is intended to be performed with a large organ such as might be found in a symphony hall or large church. The work is in two movements, and its intended performance time is twenty-five minutes. Use of the concerto format within Vox organalis results in a new approach to organizing the interaction between the solo part and the orchestral accompaniment. The organ part is notated in traditional metered notation, but the orchestral notation is organized in units of clock time (seconds). The horizontal spatial arrangement of the orchestral notation corresponds to the timing of the metered organ part. Pitch organization in Vox Oraanalis is derived from a twelve-tone row based upon the natural harmonic series. Several techniques of serial composition were used to organize and select elements of the tone row for use in the construction of the work. Use of the tone row for horizontal and vertical pitch structures provides unity to the pitch organization of the work. Vox Organalis is constructed in …

Mass/360 is computer music in the sense that the audio tape was realized with a computer language for digital synthesis. This tape is combined with traditional choral and instrumental forces, and demonstrates only one technique available for the use of computers in composition. The work displays a number of elements which afford both unity and contrast. The arch span of the whole is supported by timbral, melodic, rhythmic, and textural parameters. Recurring events include tone clusters, chant-like melodies, angular melodies, and counterpoint. Special vocal effects are found in all movements, and the large scale tonicizing effect of the movement from f to b-flat gives the composition a sense of direction over a long temporal span. The single pitch (doubled unison/octave) arises as the major event in the work, and other events are generated from this element. The use of different formal designs within each movement corresponds to the natural textual divisions found in the liturgy, and affords a contrast from one movement to the next. The relationship of the Gloria/Qui Tollis to the Sanctus/Benedictus, which is not a mirror relation, contrasts with the chiastic design of the whole. Traditional contrapuntal devices juxtaposed against contemporary vocal techniques and the use of …

Discusses the creation and performance at a concert on Feb. 12, 1990, in the Merrill Ellis Intermedia Theater at the University of North Texas of three computer music-intermedia compositions: Shakespeare quartet for 4 acoustic guitars; A noite, porem, rangeu e quebrou, for instrument of low pitch range, tape and computer; and Help me remember, for performer, Synclavier, interactive MIDI computer music system and slides.

Cenotaph is a work of fifteen minutes duration for solo tape realized on the Synclavier Digital Music System at the Center for Experimental Music and Intermedia. All of the sound materials in the work consist of resynthesized timbres derived from the analysis of digital recordings of seven different human voices, each speaking the last name of one of the Challenger astronauts. The work's harmonic resources are derived in a unique way involving partitioning of the octave by powers of the Golden Section. The work is in a single movement divided into three sections which function as prologue, action, and epilogue, respectively. This formal structure is reinforced by differentiation of harmonicmaterials and texture. Although Cenotaph cannot be performed "live" and exists only as a recording, a graphic score is included to assist analysis and study.

Sacred Symphony is a work for orchestra, chorus and 8 soloists. It is scored for three horns in F, three trumpets in B flat (1st doubling trumpet in C), tenor trombone, bass trombone, percussion, celesta, piano and strings. The percussion consists of suspended cymbal, glockenspiel, vibraphone, marimba, bass marimba, tenor drum, snare drum, bass drum, two slit drums (4 tom-toms if unavailable), small triangle, and finger cymbals. The work is in three movements: Sanctus, Beatitudes (Matt. 5: 3-12) and Gloria. The Sanctus primarily gives glory to God the Father while the Beatitudes are Christ's own words. The Gloria acts as a culmination of the previous two movements because it gives glory to both the Father and the Son.

Distant Thoughts: Dreams and Reflections, A Suite for Symphonic Winds, is a seventeen-minute work composed for the high school level wind ensemble.

Gestures and Fields is a twenty minute work for chamber orchestra and dancers. It is scored for flute (doubling piccolo), oboe (doubling English horn), Bb clarinet (doubling Eb clarinet), bassoon Bb trumpet, French horn, trombone, tuba, percussion, piano, and strings. The percussion consists of a suspended cymbal, large tam-tam, 5 temple blocks, xylophone, marimba, tumba, snare, tenor drum, 4 tom-toms, bass drum and timpani. The work is in 5 movements, each inspired by an abstract expressionist painting: Autumn Rhythm by Jackson Pollock, Light, Earth and Blue by Mark Rothko, Mahoning by Franz Kline, Vir Heroicus Sublimus by Barnett Newman, and Excavation by Willem de Kooning.

The Symphony has been composed using traditional Korean idioms and Western style four-movement arrangement. The Symphony requires Western instrumental forces. The discussions about Far Eastern music raised by Western and Eastern scholars, and about some Korean rhythmic aspects, articulations, and ornamentations help explain how the Symphony is constructed. The pitch materials, melodic styles, rhythm, form, and structural materials that are used in the composition are presented. Heterophony, embellishment, articulation, and mutation are also discussed.

Mysterium Cosmographicum is a musical chronicle of an astronomy treatise by the German astronomer Johannes Kepler (1571-1630). Kepler's Mysterium cosmographicum (Tubingen, 1596), or "Secret of the Universe," was a means by which he justified the existence of the six planets discovered during his lifetime. Kepler, through flawless a priori reasoning, goes to great lengths to explain that the reason there are six and only six planets (Mercury, Venus, Earth, Mars, Jupiter, and Saturn) is because God had placed one of the five regular solids (tetrahedron, cube, octa-, dodeca-, and icosahedron) around each orbiting body. Needless to say, the publication was not very successful, nor did it gain much comment from Kepler's peers, Galileo Galilei (1564-1642) and Tycho Brahe (1546-1601). But hidden within the Mysterium cosmographicum. almost like a new planet waiting to be discovered, is one of Kepler's three laws of planetary motion, a law that held true for planets discovered long after Kepler's life-time. Mysterium Cosmographicum is a monologue with music in three parts for orchestra, narrator/actor, and computer music on tape. All musical data structures ape generated via an interactive Pascal computer program that computes latitudinal and longitudinal coordinates For each of the nine planets as seen From …

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.

The dissertation consists of two parts: (1) the essay and (2) the composition. The essay elucidates the composer's creative process of the orchestral works, The Heidegger Collection. The Heidegger Collection has five movements. The titles of each movement are derived from the key philosophical concepts from Heidegger's most significant writing, Being and Time: (1) State-of-Mind, (2) Idle-Talk, (3) Moment-of-Vision, (4) Dread, and (5) Being-towards-the-End. The essay discusses the meanings of the five concepts, and explains how I express my reaction to Heidegger's thinking through music composition. The essay also discusses the essential musical language of The Heidegger Collection, such as interval cycles, polyrhythmic patterns, algorithmic elements, portamento effects, chaos theory, and oriental influence.
