Lindy Hop festivals and congresses

The Lindy Hop is a dance based on the popular Charleston and named for Charles Lindbergh's Atlantic crossing in 1927. It evolved in Harlem, New York City in the 1920s and '30s and originally evolved with the jazz music of that time. Lindy was a fusion of many dances that preceded it or were popular during its development but is mainly based on jazz, tap, breakaway and Charleston. It is frequently described as a jazz dance and is a member of the swing dance family.

In its development, the Lindy Hop combined both partnered and solo dancing by using the movements and improvisation of black dances along with the formal eight-count structure of European partner dances. This is most clearly illustrated in the Lindy's basic step, the swingout. In this step's open position, each dancer is generally connected hand-to-hand; in its closed position, men and women are connected as though in an embrace.
