The Sun Dance is a ceremony practiced by a number of Native American tribes. This ceremony was one of the most important rituals practiced by the North American Plains Indians. Each tribe has its own distinct rituals and methods of performing the dance, but many of the ceremonies have features in common, including dancing, singing, praying, drumming, the experience of visions, fasting, and in some cases piercing of the chest or back.
