The aim of this study is to analyse dance-music modalities in order to verify recurrent precesses which provoke the sense of interdependence between music and dance. The research design was developed to (a) extract perception-based parameters from media and kinesthetic signals (low-level), (b) validate this information by combining annotation techniques (high-level) from ecological context and © evaluate the processes by injecting controlled ambiguity (noise) and controlling reactions in context.
