Study title

This data release relates to the topic of interactions in music performance. The data consists of annotations, movement and audio descriptors, and computational predictions of interactions in jazz duos. The jazz duos are represented by 15 pulsed (standard jazz) improvisations and 15 non-pulsed improvisations (free jazz) examples, which have been documented previously (Moran et al., 2015) and the videos have been released separately. Here we release only the numerical data used in the evaluation of wavelet-based methods to estimate the interactive bouts within the performances. The data release is organized in two experiments, which are documented separately.Group music-making is a distinctive mode of human social interaction: it is a widespread activity that showcases the remarkable capacity for precision and creativity demonstrated in the coordination of rhythmic behaviour between individuals. Such coordination entails interpersonal entrainment, a process whereby two or more individuals interact with each other in a manner supporting the synchronization of body movements and musical sounds. Although musical entrainment is prevalent across the world's cultures, the way in which it is manifested appears to vary as a function of differences in social, ritual and musical conventions. A better understanding of the process of interpersonal entrainment and its cultural variation is therefore imperative. The main objective of this project is to investigate key aspects of interpersonal musical entrainment in a comparative study of a variety of cultural settings; it does so through the establishment of an international and interdisciplinary team, and by creating and analyzing a shared corpus of prepared and annotated performance data. Understanding musical entrainment requires contributions from several disciplines, in particular ethnomusicology, music cognition and computing. This project combines perspectives from each of these disciplines: it focuses on better...
