Swingdances exist in all kinds of shapes, figures, rythms and from slow to fast.
One of the most popular swingdances called the Lindy Hop is a partner dance that originated in the 1940s in Harlem. It was influenced by popular dances of the time, like the Charleston and the Foxtrott, and danced to swinging jazz music. Nowadays a lot of different styles and variants exist, making the Lindy Hop a very universal dance for different musical styles, tempos and eras.
One of the most popular Ballroom in the development of the Lindy Hop was the Savoy Ballroom in Harlem, one of the first where people of colour and white people where allowed to dance together. Even though Lindy Hop is known for it's aerials (where one or both partners are flying trough the air) today it's mostly danced as social dancing. Aerials are just used for performance or competition.
