Early history. The Viennese Waltz, so called to distinguish it from the Waltz and the French Waltz, is the oldest of the current ballroom dances. It emerged in the second half of the 18th century from the German dance and the LÃ¤ndler in Austria and was both popular and subject to criticism.
The Tango is a mixture of dances peculiar to Blacks in Haiti, Cuba and Argentina. Both the music and the dance were intense and erotic. Tango was first danced in Europe before World War I. It originates from Buenos Aires (Argentina) where it was first danced in the ghetto of Buenos Aires. It was then known under the name of Baile con corte (dance with a rest).
