There are essentially three types of Tango – Argentine, American and International Style. Argentine Tango: (arrabalero) A dance created by the Gauchos in Buenos Aires. It was actually an attempt on their part to imitate the Spanish dance except that they danced it in a closed ballroom position. The Tango caused a sensation and was soon to be seen the world over in a more subdued version. American Tango: Unlike the Argentine Tango, in which the dancer interprets the music spontaneously without any predetermined slows or quicks, the American Tango features a structure which is correlated to the musical phrasing. The dance is executed both in closed position and in various types of extravagant dance relationships which incorporate a particular freedom of expression that is not present in the International style. International Tango: This is a highly disciplined and distinctively structured form of the Tango which is accepted worldwide as the format for dance sport events. The dancers remain in traditional closed position throughout and expresses both legato and staccato aspects of the type of music appropriate to this style.
