Partner dances are the dances whose basic choreography involves coordinated dancing of two partners, as opposed to individuals dancing alone or individually in a non-coordinated manner, and as opposed to groups of people dancing simultaneously in a coordinated manner.
In many partner dances, one, typically a man, is the lead; the other, typically a woman, is the follow. As a rule, they maintain connection with each other. In some dances the connection is loose and called dance handhold. In other dances the connection involves body contact.
