Theatre is the branch of the performing arts defined as simply as what "occurs when one or more human beings, isolated in time and/or space, present themselves to another or others." By this broad definition, theatre has existed since the dawn of man, as a result of human tendency for story telling. Since its inception, theatre has come to take on many forms, often utilizing elements such as speech, gesture, music, dance, and spectacle, combining the other performing arts, often as well as the visual arts, into a single artistic form. Modern Western theatre is dominated by realism, although many other forms, including classical and experimental forms, as well as Eastern forms, are frequently performed.
