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.
