Set is called the spatial frame where the play takes place. The set, usually described by the author at the beginning of each scene, allows the reader to place the characters in a determinable and visually representable context. In turn, this description allows the actors of the theatrical work to organize their performances in a spatial framework, giving their performances a more effective contextualization and organization.
