Peter Rosser: Composer and teacher who eschewed computers to write his challenging and notationally complex works

His works were a blur of hemi-demi-semiquavers and irrational time signatures, pushing the very limits of performance. But unlike many contemporary composers, Peter Rosser was not seduced by the power of technology as he crafted his complex scores. Where others saw limitless possibilities in computers, he railed against the “reclassification of music as sonic art”. Acoustic music was dangerous, vulnerable, human; a dialogue between writer, player, instrument and audience.
