Hymns to Inanna

Description: 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.

Continuous Material Balance Reconciliation for a Modern Plutonium Processing Facility

Description: This paper describes a safeguards approach that can be deployed at any modern plutonium processing facility to increase the level of safeguards assurance and significantly reduce the impact of safeguards on process operations. One of the most perplexing problems facing the designers of plutonium processing facilities is the constraint placed upon the limit of error of the inventory difference (LEID). The current DOE manual constrains the LEID for Category I and II material balance areas to 2 per cent of active inventory up to a Category II quantity of the material being processed. For 239Pu a Category II quantity is two kilograms. Due to the large material throughput anticipated for some of the modern plutonium facilities, the required LEID cannot be achieved reliably during a nominal two month inventory period, even by using state-of-the-science non-destructive assay (NDA) methods. The most cost-effective and least disruptive solution appears to be increasing the frequency of material balance closure and thus reducing the throughput being measured during each inventory period. Current inventory accounting practices and systems can already provide the book inventory values at any point in time. However, closing the material balance with measured values has typically required the process to be cleaned out, and in-process materials packaged and measured. This process requires one to two weeks of facility down time every two months for each inventory, thus significantly reducing productivity. To provide a solution to this problem, a non-traditional approach is proposed that will include using in-line instruments to provide measurement of the process materials on a near real-time basis. A new software component will be developed that will operate with the standard LANMAS application to provide the running material balance reconciliation, including the calculation of the inventory difference and variance propagation. The combined measurement system and software implementation will make it ...

An Examination of David Maslanka's Marimba Concerti: Arcadia II for Marimba and Percussion Ensemble and Concerto for Marimba and Band, A Lecture Recital, Together With Three Recitals of Selected Works of K.Abe, M. Burritt, J. Serry, and Others

Description: Although David Maslanka is not a percussionist, his writing for marimba shows a solid appreciation of the idiomatic possibilities developed by recent innovations for the instrument. The marimba is included in at least eighteen of his major compositions, and in most of those it is featured prominently. Both Arcadia II: Concerto for Marimba and Percussion Ensemble and Concerto for Marimba and Band display the techniques and influences that have become characteristic of his compositional style. However, they express radically different approaches to composition due primarily to Maslanka's growth as a composer. Maslanka's traditional musical training, the clear influence of diverse composers, and his sensitivity to extra-musical influences such as geographic location have resulted in a very distinct musical style. His exemplary attention to detail and sound timbres give his works an individualized stamp. The evolution of motivic gestures is the most distinctive characteristic of Maslanka's compositional process. Maslanka freely incorporates forms and structural principles of the baroque and classical periods, but these principles are not applied in a strict sense. These factors combine to produce two works that are both unique and significant in the literature for marimba. They exhibit a sensitivity to sound timbres while maintaining a mature approach to melody, harmony, and rhythm acknowledging the traditions of earlier eras. This study examines compositional techniques, aspects of formal structure, tonality, melodic content, and marimba technique found in David Maslanka's Arcadia II: Concerto for Marimba and Percussion Ensemble (1982), and Concerto for Marimba and Band (1990). Transcripts of personal interviews provide valuable insights into Maslanka's approach to composition and other issues pertinent to the study of his compositions for marimba. Biographical information and an overview of his works that include marimba will serve as background material.

Thomas Jefferson: Life lines

Description: 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 vocalists (alto, two tenors, bass) and five strings (two violins, viola, cello, double bass). Historical background for each epistolary excerpt and an explanation of the its corresponding music is found in the preface.

Reconstructions: Nine Movements for Solo Soprano, Chorus, and Wind Ensemble

Description: Reconstructions is a nine-movement composition for solo soprano, chorus, and wind ensemble using texts from several of Emily Dickinson's poems. The soloist represents the main character in this dramatic work, and the narrative structure portrays abstract moments in this character's life. While the narrative structure of the reconstructed fragments is important to the form of the composition, other elements are also significant. Pitch structures generated from set theoretical systems, in addition to cyclic and palindromic structures are utilized throughout. Timbre also delineates the form, as various combinations of instruments and chorus create an evolving environment in which the soloist resides.

Atmosphantoms

Description: This work for harp and string orchestra uses musical materials derived from a chord taken from the lydian mode. The three major formal divisions are A, B, and A'. The A and A' sections are more homophonic in texture and slower in harmonic rhythm. The B section is mostly contrapuntal. Sections A and A' are dreamy and dance-like while the B section is turbulent and unrestful. These characteristics are represented by sustained sonorities, twoagainst- three rhythmic configurations, and lilting melodic materials in sections A and A', as opposed to the fragmented, ever-changing melodic material of the B section. The interweaving of the musical materials into a consummate form represents the conversations, personalities, and exploits of these Atmosphantoms, giving the music its philosophical and conversational character.

Garden of Eden

Description: The Garden Of Eden is a ballet for four instrumental quintets: brass, woodwind, string, and percussion. Each ensemble is associated with one of four dancers: God, Adam, Eve, -and the Serpent, respectively. The duration of this ballet is approximately sixteen minutes and is divided into three parts depicting (1) the creation of the world and Adam; (2) the creation of Eve-and the warning about the tree of knowledge; and (3) the Serpent's temptation of the main characters, as well as their subsequent banishment from the garden by God. One of my reasons for composing this work was to answer an important question: how to control musical motion and emotion. Since ballet incorporates both motion in its choreography and emotion in its program, it provided a perfect medium in which to work.

Harmonic Practice in the Guitar Music of Manuel M. Ponce

Description: This investigation examines the evolution of harmonic practice in the guitar misic of the Mexican composer, Manuel M. Ponce (1882-1948). Ponces harmonic practice evolved from a simple romantic style influenced by Mexican folksong to a more complex idiom influenced by Impressionistic harmony. This study explores the change in Ponce t s harmonic practice in two ways. First, general features of Ponce's harmonic vocabulary are surveyed in excerpts from various guitar works written over a twenty year period. Second, a work from Ponce's mature style--Theme Varie et Finale-is examined in detail. Chapter III gives a survey of harmonic materials in this work, while Chapter IV reveals aspects of its structural coherence.

Roy Harris' American Symphony - 1938: A Perspective on Its Historical Significance and Autogenetic Elements With a Performance of a Reconstructed Modern Wind Ensemble Edition

Description: American composer Roy Harris began writing a symphony for the Tommy Dorsey band in 1938, but the piece was never completed. This dissertation project chronicles the events surrounding the interesting collaboration between the composer and the bandleader, including problems incurred during the rehearsal process, the eventual abandonment of the project, and the discovery of the little-known band work. The paper includes information on the composer's life and works, an in-depth discussion of the compositional technique that Harris called “autogenesis,” and a detailed analysis of the two surviving movements of the band piece. The piece is also discussed comparatively with other significant works in Harris' symphonic genre, most notably his Folksong Symphony, also known as his Fourth Symphony. A significant portion of the research and preparation for the project was spent reconstructing a modern wind ensemble edition of the two surviving movements. A complete score of the reconstructed edition is included as part of this project.

Matador

Description: 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.

jn4.gesture: An interactive composition for dance.

Description: 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 program that controls the production of the audiovisual environment. This is achieved with a discussion of background issues associated with gesture capture. A brief discussion of human-computer interface and its relationship with the arts provides an overview to the software design and mapping scenarios used to create the composition. The design of the score, a graphical user interface, is discussed as the element that synchronizes the media creation in "scenes" of the composition. This score delivers a hybrid script to the modules that controls the production of audiovisual elements. Particular modules are discussed and related to sensor mapping routines that ...

The Light, for Two Narrators and Chamber Ensemble

Description: The Light is a twenty-four minute composition for two narrators and chamber orchestra. The two narrators perform the roles of the Apostle John and Moses. After an overview of the piece and a brief history of pieces incorporating narrators, the essay focuses on my compositional process, describing how orchestration, drama, motive, and structure work together in the piece. The Light is organized as a series of five related scenes. In the first scene, God creates light. In the second scene, God places Adam and Eve into the Garden of Eden to tend it, allowing them to eat from any tree except the tree of the knowledge of good and evil. The serpent appears, Adam and Eve succumb to his evil influence, and God banishes them from the Garden of Eden. Many generations have passed when Scene Three begins. Moses relates a story from Israel's journey in the wilderness after leaving Egypt. The people had become frustrated with Moses and with God. When God sent serpents among them as punishment, they appealed to Moses to pray for them. God's answer was for Moses to make a bronze serpent and place it on a pole. Whoever looked at the serpent would live. In Scene Four, John relates his vision of final redemption. New Jerusalem descends from heaven, with the River of Life and the Tree of Life ready to bring healing to the nations. Sadly, some people are not welcomed into the city, and the drama pauses to give respectful consideration to their fate. Finally, the fifth scene celebrates the eternal victory over sin, death, and the serpent of Eden. As I composed The Light, I had in mind the dramatic profile, the general motivic progression and the fundamental structural progression. However, most of the intricate interrelationships among orchestration, drama, motive, and ...

Prayers of Adoration, Confession, Thanksgiving and Supplication: A Composition for Soprano and Chamber Ensemble

Description: This paper examines the relationship between text and music in Prayers of Adoration, Confession, Thanksgiving and Supplication - a four-movement composition, fourteen minutes in length, for soprano, clarinet, bassoon, trumpet, trombone, violin, double bass, and percussion. The text of the composition is taken from the Psalms and The Book of Common Prayer. The names and themes of the movements follow an ancient pattern for prayer identified by the acronym, A.C.T.S. Compositional considerations are contrasted to those of Igor Stravinsky and Steve Reich, with special emphasis on the use of musical structures, motives, and text-painting to highlight the meaning of religious texts.

Supplemental Studies for Mastering Extended Techniques in Three Late Twentieth-Century Works for Solo Trombone: Luciano Berio's Sequenza V, Folke Rabe's Basta and Mark Phillips' T. Rex, Together with Three Recitals of Selected Works by Wagenseil, Grøndahl, Gotkovsky, and Others

Description: Many, if not most, student trombonists have perhaps had little or no previous experience with "extended techniques"-novel or unconventional modes of sound production. To address this deficiency of experience, this document sets forth a progressive sequence of descriptive explanations and supplementary studies, which are specifically designed to assist trombonists in mastering the particular extended techniques that will prepare them to perform three of the most popular late Twentieth-Century pieces for trombone that include extended techniques-Luciano Berio's Sequenza V, Folke Rabe's Basta, and Mark Phillips' T.Rex. Following the introductory chapter, the body of the document consists of three chapters, each of which deals with one of the three solos, presenting descriptive explanations of relevant extended techniques interspersed with performance commentary (solicited from prominent trombonists) and supplementary studies (composed by the author). The studies presented in each chapter are specifically geared toward mastering the extended techniques as they relate to the music of each particular solo. They are also especially focused toward learning the more difficult passages of music in each solo.

Images of Remembered Earth

Description: 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 contrasting instrumental groupings.
