The Aesthetics of Interactive Computer Music

Abstract

This article describes the aesthetics of interactive computer music and contrasts these with aesthetic assumptions of other genres of computer music. Interactive computer music is a sub-genre of what might be called performance-oriented computer music-that is, any computer music that includes a strong performance component. This broader category requires at least one live performer joined with computer-generated or electronically produced or modified music. The genre thus incorporates both the traditional tape-plusinstrument medium (Mario Davidovsky's series of Synchronisms [e.g., Davidovsky 1988] are paradigmatic) and more recent interactive computer music-whether precomposed, improvised, randomly generated, or a mixture of these. I will narrow the focus of this article to just those works that are interactive: works wherein the performer in some way controls the electronics or the electronics affect the performer's sounds. The conceptual implications of this genre are rarely discussed. Even in works that purport to treat of the aesthetics of computer music in a general fashion, such as Keane (1986) and many essays in Heifetz (1989), the issues addressed fall short of those that are implied in addressing interactive computer music. Rather than merely creating a typology or presenting the more problematic aspects of its ontology, my aim will be to show what aesthetic qualities this music has that distinguish it from other genres of electronic and electroacoustic music as well as from other forms of music generally. Since aesthetic issues are intimately intertwined with value judgements, I also make some claims about the relative value of various approaches to computer-extended performance and their possibilities. After a brief discussion of some definitional and ontological issues (simply to set the boundaries of discussion), I turn to the main points of the article. These are considered under two broad, complementary headings: (1) the human performer's contribution to computer music, and (2) the computer's contribution to human performance. Within these broad sections, there is a background theme involving the nature and relationship of the human element to the machine element. In a great deal of music since the advent of electronic sound production, the electronic elements have been used to imply the non-human; this is one reason electronic music has been so often used in science fiction films. This is some-
