Escuela de Tango de Buenos Aires is an institution dedicated to preserve and promote the Tango. In ETBA we understand that Tango is more than one type of music or dance style. The Tango is a cultural expression that emerges in the late nineteenth century in the socially and economically marginalized areas of the Rio de la Plata. As cultural expression Tango is a living entity, which is expressed and developed in the milonga. At its peak, known as the golden era (1920-1955), the Tango had already crossed borders and captivated the dance halls of the great cities of the world, but certainly is in Buenos Aires where tango is expressed and develops more fully.
