It is Latin dance, the most primitive derivative dance of mambo, and the most popular Latin ballroom dance in the United States in the 1950s.
It happens to be a rookie of Latin dance, which first appeared in American dance halls in the early 1950s, and developed from a dance called mambo.
The original spirit of cha-cha dance should be enthusiastic but not serious, and staccato is added to let dancers create a "naughty" atmosphere for the audience.
It is the most popular Latin dance. Music is easy to identify, and melody notes are usually short notes or skipping. The beat of music is 4/4 beat, sometimes 2/4 beat. Although Chacha dance often beats 34 bars per minute, the ideal beat is actually 32 bars per minute.
