This presents a different form of a psychodrama. As creativity and spontaneity are explored, I am continually struck by the beauty, expansiveness, and wonderful differences of the modality.
You can use dance as a warm-up. Have group members use movement and "dance out" something from their life. To help those with no rhythm, have everyone dance at the same time, which gives the dance-challenged encouragement and helps them hide a little. The important element is for people to re-experience something from their lives.
The dance warm-up can be expanded. Ask for volunteers (protagonists) to dance out a part of their life. Auxiliary ego and double dancers can be added. Use role reversals and other psychodrama interventions. Direct it as with any psychodrama. You can do a director's interview to determine the gist of the dance; it's time, place, circumstance, and auxiliary egos. It's important to either dance in silence or with words and sounds.
I'm sure you will enjoy the video mentioned in the first paragraph.
Moreno would approve.
