Monks, Shamans, Drum Beats, Primitive Cultures, Rhythmic Sound & The Brain
Studies have shown that vibrations from rhythmic sounds have a profound effect on brain activity. In shamanic traditions, drums were used in periodic rhythm to transport the shaman into other realms of reality. The vibrations from this constant rhythm affected the brain in a very specific manner, allowing the shaman to achieve an altered state of mind and journey out of his or her body .
Brain pattern studies conducted by researcher Melinda Maxfield into the (SSC) Shamanic State of Consciousness found that the steady rhythmic beat of the drum struck four and one half times per second was the key to transporting a shaman into the deepest part of his shamanic state of consciousness. It is no coincidence that 4.5 beats, or cycles per second corresponds to the trance like state of theta brain wave activity. In direct correlation, we see similar effects brought on by the constant and rhythmic drone of Tibetan Buddhist chants, which transport the monks and even other listeners into realms of blissful meditation.
The gentle pulsating rhythms (binaural beat) of our brain synchronization tapes act in a similar fashion, yet because the frequencies are computer generated, they are precise, consistent and can be targeted to induce highly specific and desired brain states. Much like tuning a radio to get a particular station, our brain synchronization tapes can induce a variety of brain states.

There are frequencies/rhythms which when dominant in the brain correlate with a specific state of mind. There are generally 4 groupings of brain waves:
1. Beta waves range between 13-40 HZ. The beta state is associated with peak concentration, heightened alertness and visual acuity. Nobel Prize Winner, Sir Francis Crick and other scientists believe that the 40HZ beta frequency used on many Brain Sync tapes may be key to the act of cognition.
2. Alpha waves range between 7-12 HZ. This is a place of deep relaxation, but not quite meditation. In Alpha, we begin to access the wealth of creativity that lies just below our conscious awareness - it is the gateway, the entry point that leads into deeper states of consciousness. Alpha is also the home of the window frequency known as the Schumann Resonance, which is the resonant frequency of the earth's electromagnetic field.
3. Theta waves range between 4-7 HZ. Theta is one of the more elusive and extraordinary realms we can explore. It is also known as the twilight state which we normally only experience fleetingly as we rise up out of the depths of delta upon waking, or drifting off to sleep. In theta we are in a waking dream, vivid imagery flashes before the mind's eye and we are receptive to information beyond our normal conscious awareness. During the Theta state many find they are capable of comprehending advanced concepts and relationships that become incomprehensible when returning to Alpha or Beta states. Theta has also been identified as the gateway to learning and memory. Theta meditation increases creativity, enhances learning, reduces stress and awakens intuition and other extrasensory perception skills. When the brain is in Theta it appears to balance sodium/potassium ratios which are responsible for the transport of chemicals through brain cell membranes. This appears to play a role in rejuvenating the fatigued brain.
4. Delta waves range between 0-4 HZ. Delta is associated with deep sleep. In addition, certain frequencies in the delta range trigger the release of Growth Hormone beneficial for healing and regeneration. This is why sleep, deep restorative sleep is so essential to the healing process.
