Theatre studies (sometimes referred to as theatrology or dramatics) is the study of theatrical performance in relation to its literary, physical, psychobiological, sociological, and historical contexts. It is an interdisciplinary field which also encompasses the study of theatrical aesthetics and semiotics.A late-20th-century development in the area has been the ethnographic theory of theatre, pioneered by the Russian scholar Larisa Ivleva who studied the influence of folk culture.
Dance is a performing art form consisting of sequences of movement, either improvised or purposefully selected. This movement has aesthetic and often symbolic value.Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin.
An important distinction is to be drawn between the contexts of theatrical and participatory dance,[5] although these two categories are not always completely separate; both may have special functions, whether social, ceremonial, competitive, erotic, martial, or sacred/liturgical. Other forms of human movement are sometimes said to have a dance-like quality, including martial arts, gymnastics, cheerleading, figure skating, synchronized swimming, marching bands, and many other forms of athletics.
