GranCloud is new application for the generation of real-time granular synthesis in the SuperCollider programming environment. Although the software was initially programmed for use in the interactive composition Creo, it was implemented as an independent program for use in any computer music project. GranCloud consists of a set of SuperCollider classes representing granular clouds and parameter objects defining control data for the synthesis. The software is very flexible, allowing users to create their own grain synthesis definitions and control parameters. Cloud objects encapsulate all of the control data and methods necessary to render virtually any type of granular synthesis. Parameter objects provide several simple methods for mapping grain parameters to complex changing data sets or to external data sources. GranCloud simplifies the complex task of generating granular synthesis, allowing composers to focus less on technological issues and more on musical considerations during the compositional process.

When the dust settles, John Adams’s Nixon in China and Philip Glass’s Einstein on the Beach may stand as the most important operas of the latter twentieth century. The critical essay portion of this thesis examines the trajectory of minimalist opera, from its beginnings with Glass’s Einstein on the Beach through the more romantic operas of John Adams, Steve Reich’s multimedia opera The Cave, David Lang’s musical-influenced The Difficulty of Crossing a Field, and finally the post-minimalist operas currently being staged by young composer Nico Muhly. It examines the differences between the more abstract trajectory established by the early Glass operas and the plot driven trajectory established by operas more commonly associated with John Adams, most significantly Nixon in China. Additionally, the aforementioned pieces are compared and contrasted with the author’s newly composed chamber opera Violetting through August’s End (or the sunset in water, the carillon-chime in square).

Concerto for Solo Percussion and Concert Band was commissioned by Staff Sergeant Rone Sparrow, a percussionist with the West Point Military Academy Band. Funding for the project was provided by the Barlow Foundation. The piece was premiered April 13, 2005 in the Eisenhower Hall Theater at West Point, New York. Rone Sparrow performed with the USMA band, and Colonel Thomas Rotondi Jr., Commander/Conductor, conducted the piece. The concerto consists of three movements, and each movement features a different instrument: the first features marimba, the second, vibraphone, and the third movement features the drum kit together with a rhythm section (piano, bass, and drums). In addition to the piece, the dissertation paper discusses important technical detail related to the piece, including: harmony, form, rhythm, programmatic ideas as they relate to motivic strands, and the process of generating and discarding material. The paper also focuses on a number of factors that were influential to the piece, such as postmodern philosophy.
