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 …

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.]

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

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 …

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. The instrumentation is based on the typical high school band resources. Instrumentation includes piccolo, two flutes, two oboes, English horn, three clarinets, bass clarinet, two alto saxophones, tenor saxophone, baritone saxophone, two bassoons, four trumpets, four horns, two trombones, bass trombone, two euphoniums, two tubas, timpani, and four percussionists.

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.

Earth Ascending is a composition in three movements scored for female voice, electroacoustic music, and video. Composed in the Year 2000, Earth Ascending lasts approximately sixteen minutes and was created specifically for live performance in which all three elements combine to create a sonic and visual environment. As such, no single element has greater importance than any other, with each of the three performing forces assuming a foreground role at various times throughout the work. Earth Ascending is defined by a single poem written by contemporary female British poets Jeni Counzyn, Jehanne Mehta, and Cynthia Fuller. The movements are named according to the title of each poem: Earth-Body, Light-Body; Wringcliff Beach; and Pool. The movements are separated in performance by five seconds of silence and black on the video screen. The paper accompanying the score of Earth Ascending is divided into five chapters, each discussing in detail an element central to the composition itself. The Introduction presents background information, general ideas, and approaches undertaken when creating the work. Chapters 1 through 3 investigate in detail the content of the electroacoustic music, voice, and video. Chapter 4 discusses scoring techniques, revealing approaches and methods undertaken to solve issues relating to notation …

Thomas Jefferson: Life Lines is a five movement composition based on excerpts from Thomas Jefferson's personal letters. The material presented focuses on the intimate, human qualities of the man. The musical treatment of this material illuminates and amplifies different aspects of the inner Jefferson. The music is as diverse and varied as Jefferson's interests. The style, tone and form of the music are directly tied to Jefferson's words. Two fundamental components of Jefferson's being, the rational mind and the emotional heart, are musically portrayed in the introduction of the first movement. The music that follows in the first and all subsequent movements is derived from these two components. The first movement contains eight brief excerpts that highlight different aspects of Jefferson's mindset. Each of the remaining movements focuses on a single subject: The second movement, the death of Jefferson's wife, Martha; the third movement, Monticello; the fourth movement, a dialogue between Jefferson's head and heart; and the fifth movement, Jefferson's belief in the free mind. The music is presented by a chamber ensemble of twenty-two performers: five woodwinds (flute, oboe, two B-flat clarinets, bassoon), five brass (two french horns in F, trumpet in C, trombone, tuba), two percussionists, piano, four …

Snow Spell is an interactive composition for erhu, flute, cello, piano, and Max/MSP interactive computer music system. This one-movement piece, Snow Spell, is intended to depict the beauty of a snow scene by presenting four different impressions of snow envisioned by the composer through music. The definition, history, and significance of interactive music are explored. Various modes of interactivity to control signal processing modules, and technical considerations for signal routing and level control in the interactive computer music system are also explored. Chinese music elements in Snow Spell including pentatonic scales, glissandi, and quotations from the Chinese folk tune River of Sorrow are investigated.

MCABC 0475 is the first composition generated by MCABC (Music Composition Aided by Computer), a computer program written in PL/1. Its duration is approximately 14 minutes. Using a North Texas State University computer library program, the full score and parts were drawn by the CALCOMP plotter. The text, which discusses processes and procedures in developing MCABC 0475, as well as indeterminacy, aesthetics of computer composition, and pro gr am user information, was printed by the IBM 1403 line printer using an ALA chain which has both upper and lower case characters.

In the Midst of Spoils is a setting, for SATB choir and small instrumental ensemble, of the poem "Blight," by Ralph Waldo Emerson. Emerson's poem contrasts modern man's exploitative attitude toward nature with the more reverent attitude assumed by ancient or primitive cultures. This setting is in a single movement, approximately twenty minutes in duration, consisting of fifteen distinct sections.

This dissertation explores the analysis and creation of compositions from the standpoint of texture and momentum. It is comprised of four chapters. The first presents a number of concepts as tools for analysis, including textural typography and transformation, perception of time and psychological engagement of an audience, and respiration as a metaphor for musical momentum. The second and third chapters apply these tools to Gerard Grisey's "Periodes" and "Partiels," and Brian Ferneyhough's "Lemma-Icon-Epigram." The fourth explores specific methodologies used in composing my dissertation piece, "Phase," including the application of number systems ranging from formal to local levels.

Inspired by Chinese poems, the overall characteristics of the work reflect the assimilation of several non-Western musical and philosophical influences such as the use of pentatonic scale patterns, the principle of embellishing a single note, and the application of the I-Ching in dealing with active instrumental passages over a long-sustained computer music drone. Traditional Western compositional techniques such as aleatory counterpoint, serialism, and moment form are also employed in the treatment of thematic material, developmental processes and formal design.

Among the Voices Voiceless is a composition for flute (doubling piccolo), clarinet (doubling bass clarinet), viola, cello, percussion, piano, and electronics, based on the poem "What would I do without this world faceless incurious" by Samuel Beckett. The piece is a setting for disembodied voice: the vocal part exists solely in the electronics. Having no physical body, the voice is obscured as the point of empathy for the audience. In addition, instrumental solos compete for focus during the work's twenty minute duration. In passages including a soloist, the soloist functions simultaneously as antagonist and avatar to the disembodied voice. Spoken word recordings and electronic manipulation of instrumental material provides further layers of ambiguity. The companion critical essay "Among the Voices Voiceless": Setting the Words of Samuel Beckett proposes the distillation of Beckett's style into the elements of prosaicness, repetition, fragmentation, ambiguity, and symmetry. Discussions of Beckett's works such as Waiting for Godot and Molloy demonstrate these elements in his practice. This framework informs the examination of two other musical settings of Beckett's poetry: Neither by Morton Feldman and Odyssey by Roger Reynolds. Finally, these elements are used to analyze and elucidate the compositional decisions made in Among the Voices Voiceless.

Forgotten Lyres is a musical response to Percy Bysshe Shelley's poem Mutability, which depicts the fragility and unpredictable nature of human life. Four independent chamber ensembles make up the performing forces of Forgotten Lyres; the musicians evoke the topics of Shelley's text as they interact and coordinate with one another according to a variety of paradigms and without the use of a conductor. This essay focuses on the approaches to coordination within and between ensembles, and the ways in which the musicians' interactions can evoke and convey Shelley's texts. The essay also examines works by Mel Powell, Toru Takemitsu, Witold Lutoslawski, and Pierre Boulez as examples and precursors for the coordination strategies employed in Forgotten Lyres.

...I never saw another butterfly... is a twelve movement chamber work scored for SATB choir, narrator, percussion I [vibraphone, and tomtoms (4)], percussion II [timpani (4), tam-tam, snare drum, and bass drum], guitar, violins I and II, viola, and cello and is based on the book of the same name. It contains a variety of compositional techniques, forms and genres.

Temporal Distortions is 18-20 minutes in length and is written for an orchestra including 2 flutes (2nd flute doubling on piccolo), 2 oboes, 2 Bb clarinets, 2 bassoons, 2 horns, 2 trumpets, 2 trombones, timpani, 3 percussionists playing tri-toms, vibraphone, snare/tenor drum, medium suspended cymbal, Glockenspiel, bass drum, and large tam-tam; and multiple string parts for violin I a & b, violin II a & b, viola a & b, cello and double bass. Temporal Distortions was inspired by the theoretical concept of "wormholes" in space, where matter is warped through distorted passages connecting distant and diverse parts of the universe. The work is in three sections, connected without break. The first section, Space, emerges as a wide, expansive musical area where themes and gestures are freely presented. Gradually, these materials come into phase with one another, building to a climax. A transition follows, leading into the middle section, Wormholes, where the materials are frequently and suddenly transformed into other temporal elements. The third section, Comets, was inspired by the collision of the comet Shoemaker-Levy 9 with the planet Jupiter in July of 1993. Driving, underlying rhythms propel the thematic material through a series of statements which split into more …

Historically, composers have used methods in addition to inspiration in writing music. Regardless of the source materials they used, composers ultimately rely on their musical sensitivity to inform the compositional decision-making. Discuses the rotational aspects of decimals that are created from certain prime-number denominators, and focuses on the prime number 17. Shows how these decimals can be transformed by converting them to different number bases. Looks at the Golden Proportion and its use in creating formal structures. Examines compositional and aesthetic issues arising from using number series to generate the pitches, rhythms, and sections in the Concerto for Organ and Orchestra. This process of composition reveals musical gestures that may not have been discovered using more intuitively based approaches to composition. Shows how musical sensitivity was necessary in shaping the numerically derived material in order to create aesthetically satisfying music.

The Symphonic Fantasia Han-Kook oui Ja-Yeon (Nature in Korea ) is a single-movement orchestral piece, which is divided into 5 characteristic sections - each section has programmatic subtitles (Rocks, River, Sea, Wind, and Mountain) and its own idée fixe motive. The degree of texture (homophonic/polyphonic), dynamics (strong/weak), density (thick/thin), velocity (fast/slow), and orchestration (emphasizing various sections of the orchestra) is determined by depiction of the subtitles. The critical commentary of the Symphonic Fantasia Han-Kook oui Ja-Yeon (Nature in Korea ) includes a discussion of form, pitch content (melodic and harmonic), and texture of the piece. The commentary also includes a discussion of the use of programmatic subtitles (Rocks, River, Sea, Wind, and Mountain) and depiction of these concepts in the orchestration of the work. A comparison with other orchestral works is added for explanation and support of the composer's concept. Some of the other composers who are discussed in this paper include Richard Strauss (Alpine Symphony), Gustav Holst (The Planets), Frank Bridge (The Sea), Aaron Copland (Billy the Kid), and Joseph Klein (Pathways: Interior Shadows).

Galileo's Eyeglass is a celebratory work for full orchestra with standard instrumentation commemorating Galileo Galilei's discoveries of the four largest moons of Jupiter and the rings of Saturn in 1610. The composition is approximately 14 minutes in duration, and although divided thematically into four parts, the music is continuous. The work exhibits primarily a blend of contemporary styles and compositional elements, yet it is rooted in traditional tonality; furthermore, the piece is interspersed with references to Galileo's life and times, including quotations of a toccata composed by the scientist's brother, Michelangelo Galilei, transcribed from lute tablature. Chapter 1 of Part 1 investigates relevant historical threads extracted from the backdrop of Galileo's life, from reflections on the events that shape the musical program, to the selection and preparation of the period music composed by Galileo's brother. Chapter 2 discusses specific musical components of Galileo's Eyeglass, including form, musical quotations, motivic and thematic material, harmonic language, orchestration, and notation. Chapter 3 examines the principal philosophical themes behind the composition, including expressions of victory of a life well lived in spite of many obstacles. Part 2 contains the orchestral score.

Concertino consists of two movements, Paean and Dithyramb, either of which may be performed independently. Paean, a work of calm and majestic intensity, is characterized by a rhythmic pulse which is more consistently regular than that of the Dithyramb. Its three major sections form an arch, the final measures (mm. 87-95) returning to the material of the opening (mm. 1-14). The first section begins quietly, Maestoso ma sostenuto, in a very slow tempo. The activity and intensity increase until a brief, more active middle section begins in a faster tempo (Ancora piu mosso, m. 55). A fff climax (m. 63) begins in the third section (Tempo I). After a brief poco piu mosso (mm. 72-81), the opening tempo is restored (m. 82), the opening material returns (m. 87) and the final chord fades away. Dithyramb is a free and dramatic movement in which the musical material of the wind group usually contrasts with that of the string group. The piano, which has its own material, occasionally takes on the character of one group or the other as though mediating the conflict.

A body of works titled 'capriccio' have existed for over four hundred years. Most of these works are characterized by a composers abandonment of expected stylistic norms. Guided only by the fanciful whim of the composer, a capriccio exhibits extreme contrasts in the various parameters of a musical composition including melody, harmony, counterpoint, mood and texture. The composition embedded in these compositional parameters as its point of departure and development.
