Like the heart, the brain will synchronize to an outer stimulus. This is called entrainment. Brainwave entrainment uses the brain’s natural frequency following response as a tool, presenting an outer stimulus associated with certain brainwave states of either alertness, creativity, calm, deep meditation or sleep.
Brainwave entrainment can be done with pulsing light, low-energy electromagnetic fields or sound from monaural beats, binaural beats or isochronic tones.
I embed isochronic tones subtly into the music.
The tones are set at a frequency that can help you bypass the mental and emotional barriers that would normally make the mind resistant to change, making your auto-suggestions that much more effective!
Isochronic tones are a very safe form of audio brainwave stimulation. There are, however, certain groups of people and situations where it can be contraindicated. These warnings are largely precautionary in nature, because of the lack of research in these areas. See LIST OF PRECAUTIONS at the bottom of this page.
