Contra dance. Contra dance (also contradance, contra-dance and other variant spellings) is a folk dance made up of long lines of couples. It has mixed origins from English country dance, Scottish, French dance styles in the 17th century, with strong African influence from Appalachia.
Contra dances were fashionable in the United States and were considered one of the most popular social dances across class lines in the late 18th century, though these events were usually referred to as country dances until the 1780s, when the term contra dance became more common to describe these events.
