ABSTRACT
Dyadic musical performance provides an excellent framework to study interpersonal coordination because it involves multiple agents performing matched, rhythmic, and/or interactive behaviors. This chapter presents the results of a small methods-based study in which the authors explore how Canonical Correlation Analysis (CCA) can be used as a measure of interpersonal coordination within violinist dyads. Because CCA identifies linear relationships between sets of data, it is well suited to measure the extent to which musicians synchronize their behavior when performing. As this is a novel application of CCA, the chapter examines its results within the context of the Total Kinetic Energy (TKE) employed by the musicians during a performance. Like CCA, TKE is computed from motion capture data and provides a global indicator of performance behavior. The chapter accounts the coordination of the violinists' affective states and how this might affect the results of the CCA.
