The dance showcases the story of the Ramayana, which, among other things, involves the kidnapping of a beautiful woman, changing oneself into a deer, tortured singing, and a white monkey who sets everything on fire. A typical Saturday night back then, I assume. The performance doesn't include any music. Instead, the rhythm is provided by about 50 men who are seated in a circle around the torch and small performing area in the middle. They are dressed in the traditional Balinese black and white checked sarong, and continuously chant "chak-chak-chak-chak" over and over which sounds pretty impressive with that many voices at once. With a lot of arm movements and swaying, they provide both the music and the backdrop for the dancers.
One of the things that makes Bali so different than the rest of Indonesia is their religion. Bali is a Hindu majority (93%) while the rest of Indonesia is a muslim majority (86%). This makes everything, from their way of life to their culture and art forms very unique. To see a map which shows Bali (shown in green) in comparison to the rest of Indonesia, click here
