S'I' Fosse Foco, Arderei'l Mondo

Description: 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.

Mysterium Cosmographicum, for Orchestra, Narrator/Actor, and Computer Music on Tape

Description: 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 a Fixed point on Earth For any given time Frame. These coordinates are then mapped onto selected musical parameters as determined by the composer. Whenever Kepler reads From his treatise or From a lecture or correspondence, the monologue is supported by orchestral planetary data generated From the exact place, date, and time oF the treatise, lecture, or correspondence. To the best oF my knowledge, Mysterium Cosmographicum is the First composition ever written that employs planetary data as a supporting chronology to action and monologue.

Night of Glass

Description: 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.
