Chanting rhythmically while gazing at geometric figures facilitates synchronization by simultaneously engaging the verbal skills of one hemisphere and the visual skills of the other. Because each hemisphere controls the motor skills of one-half of the body, rhythmic movement can also effect synchronization. Drumming is perhaps the most effective way to induce brain wave synchronization. Musical comprehension has been found to be a joint function of left and right hemispheres. Andrew Neher conducted a series of well-known experiments whowing that the rhythms of the drum act as an auditory driving mechanism, able to drive or entrain the suject's brain waves into alpha or theta states.
