This chapter discusses shamanism, explaining the ethos and mythology of several indigenous societies, and how these belief systems relate to the design of art and music. First, a general overview of shamanism is provided, which outlines the typical role and function of a shaman. An explanation of the shamanic visionary experience, a type of altered state of consciousness, is then provided. Following this, the chapter explores a variety of visual art from indigenous shamanic cultures, including examples from San, Native American, Huichol, Tukano, and Shipibo traditions. The sound and music of shamanic and trance cultures is also discussed, with reference to Vodou, Tukano, Mazatec, Kiowa, and Mayan examples, and relevant field recordings. Through the course of this discussion, the chapter establishes a view of how shamanic art and music invoke a sense of the spirit world, which informs the subsequent discourse of Inner Sound.
