In the performing arts, including dance, theatre, and music, performers present their art through complicated interactions with their co-actors, the audiences, music, and so on. This study investigated the dynamics of these interactions, focusing on the battle scenes in breakdance as the target phenomenon, using the analysis of synchronization as a method. In the experiment, two groups of expert breakdancers (four dancers in each group) conducted six battles each (twelve battles as the sum) in a round-robin, and we measured the each dancers’ positions using motion capture system. These position data were analyzed using the distances between two dancers and step-forward away velocities [Kijima 12; Okumura 12]. The results suggested that each dancer frequently interacted with their opponents by moving in the inverse directions (called anti-phase synchronization), and also suggested that these patterns of interactions changed as the performance proceeded.
