Cross-step waltz

Cross-step waltz (originally, the French Valse Boston) is a social ballroom dance in time, performed primarily in closed position, to slower tempo waltz music (around 110 to 120 beats per minute). It is characterized by a "primary cross-step" where the Lead role crosses the right foot over the left, as the Follow role crosses the left foot over the right, on the first count of the musical measure. Cross-step waltz can travel and rotate like traditional waltzes, while the dynamic of the cross-step facilitates a wide range of traveling variations.
