Dance is the art of movement of the body, usually rhythmically and to music, using prescribed or improvised steps and gestures. "A dance" is any one prescribed sequence of such movements, or the music to which it is performed, or an event at which it takes place. Dance may also be regarded as a form of nonverbal communication recognisable in other animals; in bee dances and behaviour patterns such as mating dances.Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music.
Traditional folk music has been defined in several ways: as music transmitted orally, or as music with unknown composers. It has been contrasted with commercial and classical styles. One meaning often given is that of old songs, with no known composers; another is music that has been transmitted and evolved by a process of oral transmission or performed by custom over a long period of time.
