David Tudor is remembered today in two guises: as an extraordinary pianist of post-war avant-garde music who worked closely with composers like John Cage and Karlheinz Stockhausen and as a founding figure of live-electronic music. His early realization of indeterminate graphic scores and his later performances using homemade modular instruments both inspired a whole generation of musicians. But his reticence, his unorthodox approaches, and the diversity of his creative output — which began with the organ and ended with visual art — have kept Tudor a puzzle.Illustrated with more than 300 images of diagrams, schematics, and photographs of Tudor's instruments, Reminded by the Instruments sets out to solve the puzzle of David Tudor by applying Tudor's own methods for approaching the materials of others to the vast archive of materials that he himself left behind. You Nakai deftly patches together instruments, electronic circuits, sketches, diagrams, recordings, letters, receipts, customs declaration forms, and testimonies like modular pieces of a giant puzzle to reveal the long-hidden nature of Tudor's creative process. Rejecting the established narrative of Tudor as a performer-turned-composer, this book presents a lively portrait of an artist whose activity always merged both of these roles. In reading Tudor's electronic devices as musicological 'texts' and examining his idiosyncratic use of electronic circuits, Nakai undermines discourses on sound and illuminates our understanding of the instruments behind the sounds in post-war experimental music.
