Why do people create Modern Dance?

      According to “Discourse on the Origin and Basis of Inequality Among Men” by Jean-Jacque Russeau[i], there are already songs, rhythms and dancing in where many people come together.  That means people have been dancing since ancient time.

I think dance is categorized into three parts which are dancing for audience, for dancers themselves and for God.

The 1^st dancing was performed for Kings and Queens at the medieval period in Europe and the 3^nd dancing is used for anthropologic understanding like folk or ethnic dancing.

However, I think Modern dance is categorized in the 2^nd dancing.

      People often say Modern dance appeals to the soul of dancers which can come along on stage.  It’s a quite different and unique point of dramas or plays which has each role of section, for example, director, actor, set manager, light designer and so on.

Modern dancers can create anything that they can image by themselves.  

      Mary Wigman who is a top leader of German expression modern dance was dancing in front of the patients in sanatorium to heal them and herself.  So Modern dance has a strong character of its origin, a dancer is also a choreographer and has many possibilities to project universally themes about individuals.
