In comparing oratorio traits across history, three aspects of oratorio were found to be particularly applicable to the creation of "Deborah: A Chamber Oratorio in One Act." These aspects were: the selection of topic and the creation or adaptation of text; the differences between recitative and aria, in form and function; and the level of stylistic diversity within a given work.

This paper discusses several compositions that use the computer screen to present music notation to performers. Three of these compositions, Law of Fives (2015), Polytera II (2016), and Terraformation (2016–17), employ strategies that allow the notation to change during the performance of the work as the product of composer-regulated algorithmic generation and performer interaction. New methodologies, implemented using Cycling74's Max software, facilitate performance of these works by allowing effective control of generation and on-screen display of notation; these include an application called VizScore, which delivers notation and conducts through it in real-time, and a development environment for real-time notation using the Bach extensions and graphical overlays around them. These tools support a concept of cartographic composition, in which a composer maps a range of potential behaviors that are mediated by human or algorithmic systems or some combination of the two. Notational variation in performance relies on computer algorithms that can both generate novel ideas and be subject to formal plans designed by the composer. This requires a broader discussion of the underlying algorithms and control mechanisms in the context of algorithmic art in general. Terraformation, for viola and computer, uses a model of the performer's physical actions to constrain the …

Virtual Stage is a project to use Virtual Reality (VR) technology as an audiovisual performance interface. The depth of control, modularity of design, and user immersion aim to solve some of the representational problems in interactive audiovisual art and the control problems in digital musical instruments. Creating feedback between interaction and perception, the VR environment references the viewer's behavioral intuition developed in the real world, facilitating clarity in the understanding of artistic representation. The critical essay discusses of interactive behavior, game mechanics, interface implementations, and technical developments to express the structures and performance possibilities. This discussion uses Virtual Stage as an example with specific aesthetic and technical solutions, but addresses archetypal concerns in interactive audiovisual art. The creative documentation lists the interactive functions present in Virtual Stage as well as code reproductions of selected technical solutions. The included code excerpts document novel approaches to virtual reality implementation and acoustic physical modeling of musical instruments.

Act one of The Metamorphosis is based on the novella by Franza Kafka of the same title. In the writing of the act, George Benjamin's Into the Little Hill and Oliver Knussen's Where the Wild Things Are provide a model of using musical material as a storytelling device. Benjamin emphasizes the parallel nature of Crimp's text through the manipulation of similar music between the acts. Knussen uses form and color to emphasize Max's childlike energy and his desire to return home. In act one of The Metamorphosis these approaches are combined to enhance Kafka's absurd narrative through a rapid collage of texture and form that is influenced by both events and characters in the opera.

This paper presents a discussion of functional silence in contemporary classical music with a particular focus on the music of Salvatore Sciarrino and Jürg Frey, two composers whose drastically-contrasting bodies of work both occupy the interstitial space between the audible and inaudible. To begin, I address three main questions: what are the functions of silence in a musical context, how do the characteristics of a work affect our perception of these silences, and how do these functions relate to our perception of music on the edge of silence. In answering these first two questions, I discuss three categories of silence---temporal, spatial, and gestural---which I use in a silence-centric analyses of Sciarrino's Let me die before I wake, Allegoria della notte, and Infinito Nero, as well as Frey's Streichquarttet III. To further apply these concepts to music on the edge of silence, I provide a fourth category---timbral silence---which describes the perception of absence or silence within the presence of sound and allows for the application of existing functional principles of silence to sounding events. In turn, this allows us to understand the music of Sciarrino and Frey in terms of timbral completion and timbral dissolution, respectively. Having established a theoretical framework …
