Barn Dances are community oriented gatherings that are sometimes held in barns. People do square dancing, Contra dancing, the English Country Dance and other dances. In the UK it can be called a Ceilidh, with traditional Irish or Scottish dancing. In the US people often do square dances to country music. There's often a live band and a Caller who tells people what steps to do in the dance.
