It's likely that four themes above "Origin of rhythm & music", "Synchronization of body movement", "Individual interaction" and "Multimodal integration", could be investigated independently, however, we might be able to integrate those themes if we introduce a concept "vocal learning" into our researches. To examine this idea, we use vocal learning species, such as budgerigars, songbirds and humans, in bio-psycho experiments.
