Interpersonal music entrainment in Afro-Uruguayan Candombe drumming.

The study of interpersonal entrainment in music, the process in which two or more individuals interact with each other to synchronize their body movements and the musical sounds, is a novel research strand which has shown to have implications for musicology and music perception. Candombe, one of the most characteristic and defining components of Uruguayan popular culture, has its actual roots in the traditions brought from Africa in the 18th century by the victims of the slave trade. While still being primarily associated with the Afro-Uruguayan community, it has long been adopted by the society at large. Drumming is the essential component of this tradition sharing many traits with other musics of the Afro-Atlantic cultures. All along the year, specially on weekends and public holidays, players meet at specific points to play Candombe marching on the street. Its rhythm results from the interaction of the patterns of three drums of different size and pitch, and has a common metric structure: a cycle of four beats and sixteen pulses. This paper presents the results of a series of experiments to measure interpersonal synchronization and leadership in small percussion ensembles of Candombe drumming. For this purpose, an audio-visual dataset of drumming performances was used. Five renowned Candombe drummers were recorded on a multi-track audio system and simultaneously filmed by three video cameras. The dataset also includes annotations of metrical information (beat and downbeat), and temporal location of strokes. The onsets were detected automatically from the audio tracks and then checked manually and corrected if necessary. The corpus analyzed consisted of 14 representative performances of ensembles of three to five drummers, containing a total of ca. 1300 rhythm cycles. To assess the precision of coordination among ensemble parts, an analysis of the asynchronies between onsets by different individual ensemble members in the same metric position was conducted. Leadership behaviors were analyzed by applying a method based on Granger Causality.
