Irish step dance is a type of recreational and competitive folk dance whose tradition probably grew in tandem with Ireland’s rich tradition in music. It may be performed as a solo dance or in groups and is generally characterized by a stiff upper body and quick, precise footwork. Though it originated in Ireland, this style of dance has become popular around the globe, thanks in large part to the recent productions Riverdance and Lord of the Dance. Where did Riverdance debut?
