To understand what a shamanic rattle is, it's important to have some background knowledge on shamans. Shamans use rattles as an accompaniment to many of their ceremonies, rituals, and other duties. In traditional Native American societies, the shaman is a religious or mystical expert who functions as a healer, prophet, and a custodian of cultural tradition. In some societies, the shaman is the sole performer of these roles. In others, they're merely a specialist. Shamans are supposed to use their powers to benefit the community, but in some cases, they were believed to use them for sorcery.
