Drama (Greek 'to do', 'seeing place') is the branch of the performing arts concerned with acting out stories in front of an audience. It uses speech, gesture, music, dance, sound and spectacle—indeed any one or more elements of the other performing arts. In addition to the standard narrative dialogue style of plays, theatre takes such forms as musicals, opera, ballet, illusion, mime, Indian dance, kabuki, mummers' plays, stand-up comedy, pantomime, and non-conventional or arthouse theatre.
