ha Cha is a lively, sassy latin dance which originated in Cuba. Cha Cha became a popular social ballroom dance in the United States in the early 1950’s. Cha Cha is either danced to authentic Latin music, or more contemporary Latin Pop or Latin Rock. The music is energetic and with a steady 4/4 beat. American Style Cha Cha is usually danced slightly slower than its International Style counterpart with a very slightly “delayed” action when moving over the supporting leg, allowing for a more continuously rhythmical interpretation.
