As a rhythm seeker, I spent much of my life exploring the rhythms of many of the world's shamanic and spiritual traditions. As I learned the drum ways of various world cultures, I found the same rhythmic qualities underlying all of them. Like the colors of the rainbow, each culture has its own hue or identity, yet each is a part of the whole society. Although the focus or intent differs from culture to culture, rhythmic drumming invariably has the same power and effects in all traditions. The resonant qualities and attributes of these rhythmic phenomena are universal and come into play whenever we drum.
The universal power of rhythm is the effects it has on consciousness. Recent studies have demonstrated that rhythmic drumming produces deeper self-awareness by inducing synchronous brain activity. The physical transmission of rhythmic energy to the brain synchronizes the two cerebral hemispheres. This shared resonance integrates conscious and unconscious awareness. The ability to access unconscious information through symbols and imagery facilitates psychological integration and a reintegration of self.
The ethereal rainbow arching high into the heavens symbolizes this harmonious union of intuition and intellect. In her book Voices of Our Ancestors: Cherokee Teachings from the Wisdom Fire, Dhyani Ywahoo states, "We are the rainbow, each of us. When we speak of rebuilding the 'Rainbow Bridge,' it is to bring into harmony the left and right hemispheres of the brain, to renew the flow of our intuitive mind." Regarding rhythmic stimulation, she says, "Chanting and drumming were also a significant part of the learning, balancing activity of the right and left hemispheres of the brain."
In his book Shamanism: The Neural Ecology of Consciousness and Healing, anthropologist Michael Winkelman reports that drumming also synchronizes the frontal and lower areas of the brain, integrating nonverbal information from lower brain structures into the frontal cortex, producing "feelings of insight, understanding, integration, certainty, conviction, and truth, which surpass ordinary understandings and tend to persist long after the experience, often providing foundational insights for religious and cultural traditions."
Brain hemisphere synchronization connects us to the guidance of our own intuitive knowing. Intuition reveals appropriate action in the moment for a given set of circumstances. Synchronous activity appears within consciousness as the most natural thing to do. One can readily perceive what aims are in accord with the cosmos and not waste energy on discordant pursuits. By allowing the intuition to lead the body, one attains clarity in movement. So long as one follows one's intuitive sense, one's actions will be in sync with the true self and ultimately the cosmos.
