Uncovering systematic relationships has, however, been difficult. Researchers have used the framework of embodied gestures, adapted from language research, to categorize and analyze performer’s movements. I have taken a different approach, conceptualizing ancillary movements as continuous actions in space-time within a dynamical systems framework. The framework predicts that the movements of the performer will be complexly, but systematically, related to the musical movement and that listeners will be able to hear both the metaphorical motion implied by the musical structure and the real movements of the performer. In three experiments, I adapted a set of statistical, time-series, and dynamical systems tools to music performance research to examine these predictions. In Experiment 1, I used force plate measurements to examine the postural sway of two trombonists playing two solo pieces with different musical structures in different expressive styles (normal, expressive, non-expressive).
