The distinguishing characteristic of shamanism is its focus on an ecstatic trance state in which the soul of the shaman is believed to leave his or her body and ascend to the sky (heavens) or descend into the earth (underworld). The drum, sometimes called the shaman's horse, provides the shaman a relatively easy means of controlled transcendence. Researchers have found that if a drum beat frequency of around three to four beats per second is sustained for at least fifteen minutes, it will induce significant trance states in most people, even on their first attempt. During shamanic flight, the sound of the drum serves as a guidance system, indicating where the shaman is at any moment or where they might need to go. The drumbeat also serves as an anchor, or lifeline, that the shaman follows to return to his or her body and/or exit the trance state when the trance work is complete.
The shaman's mount, namely the single-headed frame drum, originated in Siberia along with shamanism itself thousands of years ago. The word shaman comes from Siberia, and it is in this vast geographical region where shamanism proper is to be found. Siberian shamans use the frame drum to convey to the spirits of a place their greetings, any requests, and thanks. It is a spiritual practice designed to help human beings relate to all of nature. Siberia is one of the few places in the world where the shamanic heritage has remained unbroken. Read more.
