Bachata is a style of social dance from the Dominican Republic which is now danced all over the world. It is connected with bachata music.
Bachata is a social couple dance with a lead and follow that can be performed in open, semi-closed or closed position. The basic step involves an eight-count side-to-side movement, with many variations and styles that can be added. On counts 4 and 8, bachata includes an exaggerated hip check that gives it a characteristic look and differentiates it from bolero or son dancing. Counts 1 to 3 are moving to the lead's left, starting with the left foot, and counts 5 to 7 are moving to the lead's right, starting with the right foot. The hip check can be performed as a tap or slight lift of the foot for beginners. The basic dance sequence can incorporate turns and hand movements from other ballroom dances like salsa or cha-cha.
