The essay explores Dillon’s elastic shaping of pulse in the complex, groove-like textures of Ti.Re-Ti.Ke-Dha for percussion (1979) and Spleen for piano (1980). Musical motive offers a play of signal, pattern, and entropy, by analogy with cybernetic-structuralist models of constrained organic or mechanical systems. Repetition, following Bergson’s dynamic analytic of time-flow, “disappears even as it occurs.”
