Chakra Healing Solfeggio Frequencies: Sound Medicine for Chakra Balancing of the Body, Mind and Soul These are very special MP3s- they are programmed with isochronic tones, a sound therapy technique that is very powerful. Isochronic tones are regularly paced beats of a single tone; we have used the Solfeggio frequencies associated with each Chakra for these tones. You might hear these pulsing tones as a sort of “helicopter” sound. The frequencies used in this program are not only attuned to the Chakras, but also to the Earth… the isochronic tones progress along what is called the Schumann Resonances. The Schumann Resonance is the magnetic frequency of our planet Earth. The goal is, to not only realign your energy to the correct Chakra balances, but also to realign you to a feeling of balance with the planet.
