Holtzman, who holds a doctorate in computer science, provides a highly stimulating discussion of the integration of music, art, and language with recent trends in computer technology. He traces the evolution of formal abstract structures as they exist in the music of Schoenberg and Boulez, the art of Kandinsky, and the language grammars of Chomsky. Since computers have the capability to manipulate structures, the author contends that we have reached new frontiers of unexplored artistic creativity; he foresees new worlds of creative expression-that is, “virtual worlds.” This text wisely addresses the issues of dissonance in electronic music and human emotion and understanding in the creative process. Holtzman’s journey into “virtual reality,” sprinkled with a touch of Indian mysticism, is a totally intelligible, enjoyable venture.
