Timing is everything: Dance aesthetics depend on the complexity of movement kinematics

TLDR

Dance aesthetics have been studied mainly for subjective aspects such as familiarity, with little focus on objective features like speed or acceleration. We manipulated kinematic complexity by varying movement timing while keeping trajectory constant, and had dance‑naïve participants rate the videos on speed, effort, reproducibility, and enjoyment. Faster, more predictable sequences with varied velocity profiles were judged more effortful, less reproducible, and more aesthetically pleasing than slower, uniform‑velocity sequences, showing that movement timing—not just movement content—drives dance aesthetics and may generalize across styles.

Abstract

What constitutes a beautiful action? Research into dance aesthetics has largely focussed on subjective features like familiarity with the observed movement, but has rarely studied objective features like speed or acceleration. We manipulated the kinematic complexity of observed actions by creating dance sequences that varied in movement timing, but not in movement trajectory. Dance-naïve participants rated the dance videos on speed, effort, reproducibility, and enjoyment. Using linear mixed-effects modeling, we show that faster, more predictable movement sequences with varied velocity profiles are judged to be more effortful, less reproducible, and more aesthetically pleasing than slower sequences with more uniform velocity profiles. Accordingly, dance aesthetics depend not only on which movements are being performed but on how movements are executed and linked into sequences. The aesthetics of movement timing may apply across culturally-specific dance styles and predict both preference for and perceived difficulty of dance, consistent with information theory and effort heuristic accounts of aesthetic appreciation.
