Fox Trot or Waltz are two popular dances that originated in the early 20th century. Fox Trot is a smooth, gliding DANCE that is characterized by its four-beat rhythm and is often danced to jazz music. Waltz is a three-beat DANCE that is characterized by its graceful, sweeping movements and is often danced to classical music. Both dances are still popular today and are often seen at weddings, parties, and other social events.
