Even Ruud, Head of the Music and Theatre Institute in the University of Oslo says about improvissation that it is:«A vehicle for self comprehension, a means of creating and repressenting new cathegories of «non-referential» experiences. The quality of life (expressed in terms the feeling of actually living a good life) might be in relationship to this capacity of representing and making significant what we experiment in a pre-linguistic level in music´.Improvisation helps us to integrate into a group on a psychic level, making access to such experiences easy. This is something that Niklas Luhman, a contemporary communication sociologist, prove. His theories explain social systems have evolved from mutual uncertainty and unpredictable situations:«People that have taken part in ´collective, group based, free improvisations´, might have experienced the process that leads from total chaos to consensus within the frame of a common code or structure. Thus we can take such collective improvissations that occur in our field as examples of the art of social organization».Through the improvisation game we stablish a dialogue with external reality: we comment on it, change it symbolically, make dramatizations of it, etc. without suffering the same consequences that a real situation would imply.
