Alpha waves are electromagnetic oscillations in the frequency range of 8-12 Hz arising from electrical activity of
large groups of neurons in the human brain. When you tune your brain in on the Alpha binaural tone, your brain
waves tune-in into that alpha tone.

When you enhance these brainwaves you can experience ultimate relaxation (while awake), pre-sleep and pre-wake drowsiness. If you are interested in one of these states, than it would be ridiculous not to have a look at this collection. If you would rather tune in to a different binaural tone. Go back here.
