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.

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.

Symphonic Poem New Life is a composition in one movement for orchestra and yang-chin. The work is divided into six continuous sections. It is written in resultant form which is a cumulative process by which all major musical elements return at the end of the work. The tritone is the prominent interval used throughout the piece. Some graphic notation is also employed. The work has a performance time of approximately 13-15 minutes. The yang-chin is a Chinese string instrument similar to the Hungarian cymbalon, which is played with a pair of small beaters. These instruments have similar ranges, and either instrument can be used in this work.

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.

Hailstones and Birdcages is a composition of approximately thirteen minutes' duration and is scored for two flutes and piccolo, two oboes and english horn, three Eb clarinets, E clarinete, bass clarinet, two bassoons, two Eb alto saxophones, Bb tenor saxophone, three Bb trumpets, four F horns, three trombones, euphonium, two tubas, and three percussionists. Four instruments--one each of flute, oboe, Bb clarinet, and trombone--are used in concertante like fashion, and there are prominent solo passages for the first bassoon, as well. The work is a single movement in three sections, fast - slow - fast, with ritornello. and employs a free use of the total chromatic. Technically, the work is within the capabilities of an above-average high school or average college 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.

Requiem for Netted Fish is an intermedia composition for sixteen-voice SATB choir, harp, six dancers, slide projections, and lighting. The text, taken from the poetry of Anna Akhmatova and Carolyn Forche, presents a universal, womanly rage against human repression and destruction. The poetry finds aural interpretation in sound, and visual interpretation in movement and lighting. Poetic inspiration contributes to the integration of elements in the work, as does the impulse-exchange method of coordinating mediums, which allows the dancers control of the timing of events. The resultant interdependent relationships necessary for performance contribute to the integration of the composition. The duration of this intermedia work is approximately fifteen minutes.

The Sneetches is a theater piece for children based on the Dr. Suess story The Sneetches (Random House, New York, 1961). It is scored for narrator, flute, B6 clarinet, bassoon, violins I & II, viola, and cello with optional staging. The staged version of The Sneetches requires two to six actors/dancers, appropriate scenery and props, and the active participation of children from the audience, preferably ages eight or under. The Sneetches is essentially through-composed. The overall form of the music is shaped primarily by the events portrayed in the narrative. Although individual subsections may have traditional forms, they should not be viewed as independent movements of a larger work, but rather as fragments of a whole.

"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.

Concertino for Jazz Clarinet. Electric viola and Symphonic Orchestra is a composition of approximately fifteen minutes' duration, and is scored for two flutes (second doubling piccolo), two oboes, two Bb clarinets, two bassoons, four F- horns, two Bb trumpets, three trombones (third bass), two percussionists, solo Bb clarinet, solo electric viola and strings. The piece is divided into two movements; Andante and Canon. Concepts derived from jazz music are employed in, for example, harmony and improvisation in the solo parts, whereas the orchestration is mainly traditional. The piece is written for two great Swedish instrumentalists; Putte Wickman, clarinet, and Henrik Frendin, viola. Stylistically this work is difficult in the orchestral parts, since it uses concepts from two different musical styles, jazz and classical. Influences originate from such wide-ranging composers as Mozart, Stravinsky, Shostakovich and Chick Corea.

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.

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.

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.

Delphic Suite is a composition for orchestra that depicts specific events narrated in Homer's epic tale, Odyssey. For the purpose of this thesis the second movement, Raid on Ismarus, has been omitted so as to focus on the melodic, rhythmic, and harmonic structures of the first movement, Lament from Troy, and the third movement, Ruler of the Winds. Each of these musical parameters will be analyzed in order to illustrate the Suite's imitation of compositional techniques exemplified in the music of Homer's era, and the musical results obtained by juxtaposing those parameters upon a twentieth-century tonal scheme that provides the Suite with an eclectic ambience.

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.

The composition is scored for the following instruments: 2 flutes, 2 oboes, 2 clarinets, 2 bassoons and a large percussion section requiring 7 performers. Beneath the Dancing Moon is a programmatic piece in one movement form composed of 5 continuous sections. It depicts a night scene when the elves begin to dance beneath the moon. Later, the moaning ghosts from the dark forest and the witches with brooms come to join them. They dance furiously until the moon disappears, the sea stops dead and all the dancers suddenly vanish. The approximate performance time is 17 minutes.

The Reflection is a piece of chamber music that describes the human nature through the use of different "meanings" in music. By using various leitmotifs and different compositional techniques, the music becomes a helpful tool to reflect meanings. On the other hand, this piece uses one special idea, which is that the whole piece can be explained in terms of visual arts. Each primary motive represents a "primary color" that reflects various "moods" or "emotions." Through using combinations and mixtures of color, different "sceneries" are formed. Furthermore, The Reflection has three basic aspects: the function of transmitting messages through music; the exploration of different functions of fifth; and the emphasis of meaning, sound effect and timbre.

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.

Animations is a composition in six movements (Fish, Seals, Birds, Cats, Zebras, Snakes) for percussion and computer music on tape. One percussionist performs on various percussion instruments: two suspended cymbals, crotales, triangle, vibraphone, glockenspiel, marimba, three bongos, snare drum, field drum, large tom-tom, bass drum, kettle drum, temple blocks and vibraslap. The computer music on tape employs sampled sounds in a MIDI sequencing environment. The melodic and harmonic materials for the piece are derived from a matrix of twelve heptatonic scales. The individual movements are notated using both traditional and proportional notation systems. The score is 37 pages long with a twenty-two page analysis preceding the score. Animations is approximately nine minutes in duration.

The Last Seven Words is an orchestral piece with double woodwind, double brass, and two sets of timpani. The duration of the work is seventeen minutes. The forty-six pages which precede the musical score present a discussion and an analysis of the composition. The purpose of this project was to provide the composer an opportunity to write an orchestra piece with a single scale and seven rhythmic patterns.

The Crucifixion, a composition for three vocal soloists, four-part mixed chorus, and instrumental ensemble, is a setting of passages taken from the four Gospels of the Holy Bible. It describes the mocking of Christ and includes the Seven Last Words of Christ on the cross. It uses serial technique in the structuring of pitches and rhythm. Special attention is paid in designing and combining pitch and rhythm to create monophonic, homophonic and polyphonic textures. Besides traditional performance techniques, the work employs some modern vocal and instrumental techniques.

House in Heaven is a theatrical piece for five solo voices (one soprano, two mezzo sopranos, one baritone, and one bass), two trumpets, four French horns, one trombone, two flutes, two clarinets, two bassoons, string orchestra, vibraphone, timpani and a synthesizer which produces pipe organ sound. The composition consists of an introduction followed by a single act in three Scenes. The piece employs the cyclical device in engaging themes associated with particular characters. The texture grows from simple alternating dialogues to arias and, finally, to tutti passages in which all voices are combined to form a quintet, at the climactic point of the entire composition, which occurs at the end of the piece. The scenes depict imaginary events in a Church and at a flower garden. Rear-stage slide projections are used to project the scenes of these locations, and lighting is used to emphasize actions, characters and changes of scene. The singers also serve as actors. The duration of this work is approximately 20 minutes.

Ka is a one movement composition for chamber orchestra consisting of three sections. The work's harmonic, melodic and rhythmic materials are derived from the Chinese I Ching ("Book of Changes"). The middle section was composed with the aid of a computer program written by the composer. The program generated the interval sequence arrays forming the harmonic basis for the piece. Ka is scored for flute, oboe, B𝄬 clarinet, bassoon, French Horn, trumpet, trombone, three percussionists, violin, viola, cello and double bass. The score is 62 pages with a 39 page analysis preceding the score. Ka has a duration of approximately 10 minutes with no pauses between sections.

Riders to the Sea is a chamber opera in one act of approximately 40 minutes in duration. The single act is divided into six scenes that progress without pause. The vocal parts are comprised of 2 sopranos, 1 mezzo-soprano, 1 baritone, and an off-stage chorus of men's voices (tenor I, tenor II, baritone, and bass; two per part). The orchestra will be comprised of winds (1-1-1-1-1), brass (2-2-1-1), strings (2-2-2-2-1), piano, 2 percussionists, and tape, that will be used to provide a continuous background of surf and wind sounds. Authentic Irish folk songs are threaded throughout the work, generally functioning as a background element, while twentieth-century compositional techniques are utilized primarily for special effects.
