Using information theory as a foundation, this paper defines virtuosity in the context of laptop performance, outlines a number of challenges that face laptop performers and software designers, and provides solutions that have been implemented in the author's own software environment. A summary of the argument is that by creating a multi-dimensional environment of Sonic Vector Spaces (see page 17) and implementing a method for quickly traversing that environment, a performer is able to create enough information flow to achieve laptop virtuosity. At the same time, traversing this multi-dimensional environment produces a perceptible sonic language that can add structural signposts for the listener to latch on to in performance. Specifics of the author's personal approach to this problem, a software environment coded in SuperCollider, are then shared. Lastly, Mihà¡ly Csà­kszentmihà¡lyi's concept of flow psychology is applied to the three stages of creation in the laptop performance process - software design, patch design, and performance.

TransFantasies is an interdisciplinary composition for Baroque flute (flauto traverso), computer music, and dance. A crucial component of the work is an interactive hardware and software environment that provides the opportunity for the players to shape aspects of the work during the performance. This essay discusses the influences that inspired the work and presents an in-depth analysis of notable elements of the composition. Primary issues include compositional models for gesture-based composition, historical performance practices, interactivity, and relationships between music and dance. The final component of the essay details the software component designed to create the composition. It also discusses music technology in current practice and its role in this particular work. At its core, TransFantasies is concerned with those moments where computer-influenced decisions and human behaviors collide.

Computer Simulacra is a musical work composed for amplified instrumental ensemble and computer instruments on tape. It is a computer-assisted work, composed with the help of a stochastic compositional algorithm, called PTERIO, designed by the composer.

Inspired by Chinese poems, the overall characteristics of the work reflect the assimilation of several non-Western musical and philosophical influences such as the use of pentatonic scale patterns, the principle of embellishing a single note, and the application of the I-Ching in dealing with active instrumental passages over a long-sustained computer music drone. Traditional Western compositional techniques such as aleatory counterpoint, serialism, and moment form are also employed in the treatment of thematic material, developmental processes and formal design.

This thesis is about the design of software which enables groups of people to make music together. Networked musical interaction has been an important aspect of Sound and Music Computing research since the early days, although collaborative music software has yet to gain mainstream popularity, and there is currently limited research on the design of such interfaces. This thesis draws on research from Computer Supported Cooperative Work (CSCW) to explore the design of systems for Collaborative Digital Musical Interaction (CDMI). A central focus of this research is the concept of Awareness: a person’s understanding of what is happening, and of who is doing what. A novel software interface is developed and used over three experimental studies to investigate the effects different interface designs have on the way groups of musicians collaborate. Existing frameworks from CSCW are extended to accommodate the properties of music as an auditory medium, and theories of conventional musical interaction are used to elaborate on the nature of music making as a collaborative and social activity which is focused on process-oriented creativity. This research contributes to the fields of Human-Computer Interaction (HCI), Computer Supported Cooperative Work, and Sound and Music Computing through the identification of empirically derived design implications and recommendations for collaborative musical environments. These guidelines are demonstrated through the design of a hypothetical collaborative music system. This thesis also contributes towards the methodology for evaluating such systems, and considers the distinctions between CDMI and the forms of collaboration traditionally studied within CSCW.

This dissertation considers the music and technical practice of composers affiliated with French spectralism, including Hugues Dufourt, Gérard Grisey, Tristan Murail, Jean-Claude Risset, and Kaija Saariaho. They regularly described their work, which was attuned to the transformative experiences that technologies of electronic sound production and reproduction could inspire in listeners, using metaphoric appeals to construction: to designing new sounds or exploring new illusory aural phenomena. To navigate a nascent but fast-expanding world of electronic and computer music, the spectralists appealed to physical musical attributes including gesture, space, and source-cause identification. Fascinated by gradual timbral transformations, they structured some of their pieces to invite speculative causal listening even while seeking to push it to expressive extremes. I hypothesize that, much as the immersive technology of the cinema can create the illusory feeling of flight in viewers, electronic music can inspire listeners to have experiences in excess of their physical capabilities. Those feelings are possible because listening can be understood as empathetic and embodied, drawing on a listener’s embodied and ecological sensorimotor knowledge and musical imagery alongside referential, semiotic, and cultural aspects of music. One way that listeners can engage with sounds is by imagining how they would create them: what objects would be used, what kind of gestures would they perform, how much exertion would be required, what space would they inhabit. I cite recent research in psychoacoustics to argue that timbre indexes material, gesture, and affect in music listening. Technologies of sound production and reproduction allow for the manipulation of these tendencies by enabling composers to craft timbres that mimic, stretch, or subvert the timbres of real objects. Those electronic technologies also suggest manipulations to composers, by virtue of their design affordances, and perform an epistemological broadening by providing insight into the malleability of human perceptual modes. I illustrate these claims with analytic examples from Murail’s Ethers (1978), Saariaho’s Verblendungen (1984), and Grisey’s Les Chants de l’Amour (1984), relating an embodied and corporeal account of my hearing and linking it to compositional and technological features of spectral music.
