Theatre practices have also been adapted. Masks come in and out of fashion with
experimental performance. American reflections of the role of the chorus in Greek
theater shifted through the century. In the 1920s and 1930s, when constructivism
was influential, the mass movement, single voiced chorus was expanded. Since
the Poor Theatre movement of the 1960s, the actors in the chorus have been encouraged
to develop individual characters and “biographies.”
