In a musical ensemble such as a string quartet, the performers can influence each other’s actions in several aspects of the performance simultaneously. Based on a set of recorded string quartet exercises, we carried out a quantitative analysis of ensemble interdependence in four distinct dimensions of the performance: dynamics, intonation, tempo, and timbre. We investigated the fluctuations of interdependence across these four dimensions, and in relation to the exercise being performed. Our findings suggest that, although certain differences can be observed between the four dimensions, the most influential factor on ensemble interdependence is the musical task, shaped by the underlying score.
