 Traditional and modern Western square dancing have a number of calls in common, but there are usually small differences in the way they are performed.For example, the "Allemande Left" is traditionally performed by grasping left hands with the other dancer, pulling away from each other slightly, and walking halfway around a central axis then stepping through.In modern Western dance the grip is modified so that each dancer grips the forearm of the other, and there is no pulling (that is, each dancer supports his or her own weight).
