| summary | Movement and music are tightly linked. Movement determines the quality of the sounded outcome in music performance. World-class musicians can be often recognized by their specific movement style ("motor signature"). Moreover, musical rhythm has a compelling tendency to engage our body. This phenomenon can be observed when we spontaneously or deliberately synchronize to musical rhythm by foot tapping or body swaying. This property of music has been exploited to serve rehabilitation of motor deficits in patients (e.g., with neurodegenerative disorders). In this talk I will focus on these two aspects of the relationship between music and movement. In the first part two studies will be presented on movement kinematics in skilled music performance. In the first motion-capture study we tested the effects of speed on expert pianists' anticipatory finger movements, tone intensity, and timing during performance. We found that pianists' maximum finger heights above the keyboard before striking the keys increased as speed increased. In addition, finger kinematics in the vicinity of the keypress contained regions that were sufficiently unique to identify pianists. The second study focuses on timing and motor abilities of a 5-year-old drummer prodigy (IF) exhibiting very precocious and outstanding musical abilities. Both behavioral and motion capture data revealed that IF is exceptionally accurate in synchronizing movement with regular auditory stimuli. This ability to entrain to regular auditory stimuli, however, markedly hindered IF's motor performance when he played together with a nonisochronous auditory reference. In the second part of the talk I will focus on the positive effect of rhythm (in particular of sensorimotor synchronization, SMS, to auditory stimuli) on the rehabilitation of motor disorders in patients with Parkinson's disease (PD). Results on SMS obtained with a group of patients with PD will be presented, showing the usefulness of defining patients' "synchronization profile" for devising and optimizing rehabilitation strategies tailored to the patient. |
