Theatre (or theater, see spelling differences) is a branch of the performing arts. While any performance may be considered theatre, as a performing art, it focuses almost exclusively on live performers creating a self contained drama. A performance qualifies as dramatic by creating a representational illusion. By this broad definition, theatre has existed since the dawn of man, as a result of the human tendency for storytelling. Since its inception, theatre has come to take on many forms, utilizing speech, gesture, music, dance, and spectacle, combining the other performing arts, often as well as the visual arts, into a single artistic form.The word derives from the Ancient Greek theatron (θέατρον) meaning "the seeing place."
