Square dance
Square Dance is a principle form of American folk dance. To the traditional string band music and the prompting of a caller, four couples, arrange in a square, cooperate to execute various figures, moving with a smooth, shuffling step. The square dance developed about 1825-1850 out of the then fashionable cotillion and quadrille, stately French dances in square formation. ... In the 1860s the fast swinging of partners in ballroom dance position added further interest. Square dances developed regional variations in figures and style of calling, and in Canada similar dances developed with French, Scottish, and Irish influences. Country-dance is similar to square dance because it is a traditional form of folk and aristocratic dance of the British Isles, from which many variations developed.
