Although the abovementioned playwrights made some of the most renowned dramas, their staging had little or nothing to do with twentieth century theater. Their dramas were always part of a series of three performances, where just the middle part was the drama, while the events always ended with dance. The dramas rarely had more than three actors (all male), who played the different roles using masks. There was a chorus on the stage all the time which did songs and spoken word passages.
