Bollywood

Hindi dance songs are now widely heard around the world. They first became popular among overseas Indians and were eventually discovered by others.

The filmi music and dances in Bollywood films are a synthesis of formal and folk Indian traditional music and dance traditions, with the infusion of Western techniques. The dances in older Hindi movies represented supposed dances of the common people, although they involved original choreography. Bollywood dances have evolved as a unique and energetic style. Since they are group dances, they are often used as joyful exercise music.
Bollywood dances usually follow filmi songs.

The choreography of Bollywood dances takes inspiration from Indian folk dances, classical dances (like kathak) as well as disco and from earlier Hindi filmi dances.
