La Ronde is a long form structure focusing on how characters interact before they are lovers and after they are lovers. Like the play that it is based on, La Ronde, is a very structured series of scenes. Each player does 4 scenes maintaining the same character for each scene. The 1st and 2nd scenes are with 2 other characters before they have become lovers. The 3rd and 4th scenes are with the same 2 characters after they became lovers.
This is a two hander long form where the players will define their changing settings by the location of chairs on the stage. The point of difference here is that setting changes are defined by the location of chairs on the stage. Each new scene will have a corresponding chair location change. If the chairs are in the same position as a previous scene that indicates the characters have returned to the previous setting.
You are about to see as series of open scenes only connected by a single offer from the audience. They may weave into story or not. There is an acute difference from montage and other long form structures. In a montage the scenes are discrete short from narratives that follow the STEP process and are sorted before the next scene starts.
