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. Sometimes described as New England folk dance or Appalachian folk dance, contra dances can be found around the world and have much popularity in North America and the United Kingdom where weekly or monthly dances and annual dance weekends are common. According to the Contra Dance Links website, contra dancing can be found in all US states except for South Dakota.
Contra dancing is a social dance that one can attend without a partner. The dancers form couples, and the couples form sets of two couples in long lines starting from the stage and going down the length of the dance hall. Throughout the course of a dance, couples progress up and down these lines, dancing with each other couple in the line. The dance is led by a caller who teaches the sequence of figures in the dance before the music starts. Callers describe the series of steps called "figures", and in a single dance, a caller may include anywhere from 6–12 figures which are repeated as couples progress up and down the lines. Each time through the dance takes 64 beats, after which the pattern is repeated.
The music played for contra dances includes, but is not limited to Irish, Scottish, old-time and French-Canadian folk tunes. The fiddle is considered the core instrument, though other stringed instruments are used, such as the guitar, banjo, bass and mandolin, as well as the piano, accordion, flute, clarinet and more. Contra dances are even done to techno music. Music in a dance can consist of a single tune or a medley of tunes, and key changes during the course of a dance are common.
