A country dance is any of a very large number of social dances of a type that originated in the British Isles; it is the repeated execution of a predefined sequence of figures, carefully designed to fit a fixed length of music, performed by a group of people, usually in couples, in one or more sets. The figures involve interaction with your partner and/or with other dancers, usually with a progression so that you dance with everyone in your set. It is common in modern times to have a "caller" who teaches the dance and then calls the figures as you dance. Country dances are done in many different styles.

Social dances are dances that have social functions and context. Social dances are intended for participation rather than performance. They are often danced merely to socialise and for entertainment, though they may have ceremonial, competitive and erotic functions.
