Participants were required to clap their hands in time to piano performances under both conditions. While the pianist could hear the hand claps of the participants in the (a) condition, she could not in the (b) conditions. The onset time of each beat was estimated by a signal processing to the digital recordings of the piano sounds and those of clap sounds. The results suggested that the bidirectional, auditory information transmission enhances the degree of synchronization between the beat timings of the performer and those of the audience. The results of cross-correlation analysis of inter-beat interval of the performance and clapping suggest that the performer and the audience are mutually synchronized while using the information up to the past one bar.},
