It is done Napoleon's invading solders spread the waltz from Germany to Paris; then the dance glided across the channel to England and finally made its way to the United States. The waltz is done in triple time and performed in a closed position.

"Swing dance" is a group of dances that developed with the swing style of jazz music in the 1920s-1940s, with the origins of each dance predating the popular "swing era". During the swing era, there were hundreds of styles of swing dancing, but those that have survived beyond that era include: Lindy Hop, Balboa, Collegiate Shag, and Lindy Charleston. Today, the most well-known of these dances is the Lindy Hop, which originated in Harlem in the early 1930s.
