How many types of dances exist?

It is impossible to determine an exact number for the types of dances that exist because there are so many different cultures, regions, and styles of dance around the world. Dances can be categorized based on various criteria, such as origin (e.g. traditional, modern, contemporary, folk), purpose (e.g. social, ritual, performance), movement style (e.g. ballroom, hip-hop, ballet, tap), and so on. In addition, new dance forms and styles are constantly being created and evolving.
