What is the author's style in Sergeant Musgrave's Dance by John Arden?

Arden utilizes various dramatic techniques to emphasize the time and place of the action as well as develop characters. The most prominent of these are songs, poetic verse, and dances.

In the climactic scene of Serjeant Musgrave's Dance, the audience becomes part of the drama. In the marketplace, a small crowd gathers to hear the speeches. Yet because there is no crowd of townspeople beyond the handful of characters, everything is addressed to the audience. It is as if Arden is making his argument directly to the audience.
