Traditional solo dance performed in a variety of styles in the British Isles, Nova Scotia, and the US. All forms are characterized by deft, complicated footwork usually performed in a tightly restricted floor area. Many forms are percussive, the sound being produced by a range of hard shoes, such as wooden clogs, or shoes with hard leather soles or metal taps. In Ireland and parts of the US it has become a competition form, characterized by complex footwork and flamboyant aerial manœuvres, performed with a rigid torso. The show Riverdance brought Irish step dance to a world-wide audience.
