Reader's theatre or Reader's theater is a style of theater in which the actors do not memorize their lines. Actors use only vocal expression to help the audience understand the story rather than visual storytelling such as sets, costumes, intricate blocking, and movement. This style of performance of literature was initially lauded because it emphasized hearing a written text as a new way to understand literature. Readers Theatre is also known as Chamber Theatre or Interpretive Theatre. Readers Theatre became popular during and following the Second World War when resources to produce plays were scarce. There are four different types of Readers Theatre, each an evolution of the former and each with different attributes: Readers Theatre, Free Readers Theatre, Chamber Theatre, and Contemporary Readers Theatre. Each of these styles and manifestations of Readers Theatre is still performed today.
