These Alpha Brainwave Meditations consists of a combination of alpha isochronic pulses, nature sounds, ambient music, sacred “OM”, chants, and a wide variety of instruments from the flute to sacred Tibetan bowls. Brainwave entrainment or “brainwave synchronization”, is a new yet ancient science that causes brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state. It is based upon the “frequency following” response which is the human brain’s tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus. Such a stimulus is often aural (audio), in this case isochronic tones. In ancient times, drumming, chanting, etc., was used to produce profound trance states of consciousness.
We use isochronic tones because they are the most effective and can be listened to with or without headphones or from any set of speakers. Isochronic tones are separate pulses of a single tone or sound. used for brainwave entrainment. Isochronic tones work by emitting sound at regular intervals. This excites the thalamus and causes the brain to duplicate the frequency of the Isochronic tones, changing its thought patterns.
There are four main brainwave categories, which determine or mental state or state of mind. Below is a simple chart showing the frequency range and name of the four main brainwave state:
12–39 Hz / Beta waves: Active, busy or anxious thinking and active concentration, arousal, cognition, and or paranoia.
8–12 Hz / Alpha waves: Relaxation (while awake), pre-sleep and pre-wake drowsiness, REM sleep, dreams. Zen-trained meditation masters produce noticeably more alpha waves during meditation.
4–8 Hz / Theta waves: deep meditation/relaxation, NREM sleep
0–4 Hz / Delta waves: Deep dreamless sleep, loss of body awareness
