Typically, there is no hierarchy among mambos and houngans. More advanced classes incorporate dance elements such as turns, mambos, and stomps. Notable nightclubs in Goa include Chronicle, Mambos and Sinq. There are also notable mambos within the United States. Locuras, tiros y mambos is an 1951 Argentine film. The four mambos are ideal both for listening and for dance music. Women priests (named mambos) play equal roles to male priests or Houngan in Haitian vodou. Mambos, however, can speak to and hear from the Vodou spirits. As religious specialists, mambos know the Vodou spirits by their names, attributes, and symbols.
