Music and theatre are two of the oldest art forms in the world. For centuries they have been the vehicle for human creativity and emotion, and are unique in that their medium is highly experiential and provocative to the senses. Individually, they are accomplished, defined, sophisticated art forms but when coupled create a product that immerses the viewer in the synergy of sound and movement.
The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and sub genres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts," music may be classified as a performing art, a fine art, or an auditory art.
Theatre 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 had 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, writing, and spectacle, combining the other performing arts, often as well as the visual arts into a single artistic form.
