Tango is a social dance originating in Buenos Aires, Argentina. Today, there are many tango dance styles, including Argentine Tango and American and International styles of Ballroom tango. The Argentine tango is often regarded as the "authentic" tango since it is closest to that originally danced in Argentina and Uruguay, though other types of tango have developed into mature dances in their own right.
Argentine Tango consists of a variety of styles that developed in different regions and eras of Argentina and Uruguay. The dance developed in response to many cultural elements, such as the crowding of the venue and even the fashions in clothing. The styles are mostly danced in either open embrace, where lead and follow connect at arms length, or close embrace, where the lead and follow connect chest-to-chest.
