In dance, the galop, named after the fastest running gait of a horse (see gallop), a shortened version of the original term galoppade, is a lively country dance, introduced in the late 1820s to Parisian society by the Duchesse de Berry and popular in Vienna, Berlin and London. In the same closed position familiar in the waltz, the step combined a glissade with a chassé on alternate feet, ordinarily in a fast 2/4 time.
