At the simplest level, dancing is a way for people to get to know each other, not necessarily in verbal ways. This notion is reinforced by the sexually suggestive movements in some dances. Secondly, this is also about the physical act of dancing. There are many different dances, each with its own musical beat and rhythm. For two people to dance together, they must both know the dance movements insofar as the feet, the hands and the body are concerned.
Most dances are simple enough, consisting of a sequence of set movements.
Generally, these dance movements are mechanical and ritualistic, to be repeated by celebrants everywhere. Sometimes, a dance may transcend the commonplace for other reasons, such as aesthetics or lewdness. The next animated sequence shows the movements for the macarena dance. When clinically reduced down to a sequence of movements in this manner, the dance is quite insipid and lifeless. If anything, one may be striken by how absurd this ritualistic motion seems.
