The styles and types of dances at a pow wow are descended from the traditions of the Great Plains nations of Canada and the United States. Besides those for the opening and closing of a pow wow session, the most common is the "intertribal", where a Drum will sing a song and anyone who wants to can come and dance. Similar dances are the "round dance"; "crow hop" when performed by a northern drum or a "horse stealing song" by a southern drum; there is also "double beat", "sneakup" and, for Women's Traditional and Jingle, "sidestep". Each of these songs have a different step to be used during them, but are open for dancers of any style.
