There are two main categories when talking about Ballroom – or Standard – Dancing: The International Standard and American Smooth.
The International Standard style includes five dances: Waltz, Tango, Viennese Waltz, Foxtrot and Quickstep. This style is danced widely in competitions, both in the United States and throughout the world. The most obvious trait of the International Standard style is the dancers’ constant closed position, where partners never lose contact with each other.
Four of the Standard dances have their American Smooth counterparts: Waltz, Tango, Foxtrot and Viennese Waltz.
