SalsaMania - London

Leaders improvise the dance, signalling to their partners what the leader would like the partner to do next. Followers read the signals given by their partner, and respond to the lead. This allows people who have never danced with one another before to improvise a dance and dance socially with someone they have not met before.

You can ask anyone to dance, and other dancers will ask you to dance with them. A good leader will pick up the skill level and preferred dancing style of their partner and lead accordingly.
