Performance studies is the academic field concerned with the study of performance in any of its various forms. The term 'performance' is broad, and can include artistic and aesthetic performances like concerts, theatrical events, and performance art; sporting events; social, political and religious events like rituals, ceremonies, proclamations and public decisions; certain kinds of language use; and those components of identity which require someone to do, rather than just be, something. Consequently, performance studies is interdisciplinary, drawing from theories of the performing arts, anthropology and sociology, literary theory, and legal studies.
