Aberrations in the constancy and duration of movement challenge the determination of bodies and things within and beyond dance. In fact, 19 th -century anthropological studies on animism and recent cognitive science experiments on timescale bias demonstrate that the agency of erratic motion is difficult to apprehend. From irregular and unexpected movements in dance to the variable tempos of cell motility, this paper considers how arrhythmic choreography recalibrates the agency of matter, objects, bodies and environments.
