 Performance in some groups is also guided by principles based on Zen Buddhism. For instance, among other concepts, the San Francisco Taiko Dojo is guided by rei (礼) emphasizing communication, respect, and harmony. The way the bachi are held can also be significant; for some groups, bachi represent a spiritual link between the body and the sky. Some physical parts of taiko, like the drum body, its skin, and the tacks also hold symbolic significance in Buddhism.
