Cha-Cha is a popular Afro-Cuban dance that is often danced at ballroom dance events as well as Latin clubs.
Cha-cha music is written in 4/4 time and around 30 measures per minute (120 beats per minute) with a medium-to-fast, syncopated feel.
Cha-cha is generally done with a partner, which means the leader will control the flow of the dance, guiding the follower and deciding what patterns to do, while the follower will try to match the leader's movements and timing.
