Sound frequencies effect everything about us. The correct vibrational frequencies can be used to heal and balance our bodies. Sound healing is the practice of using sound to realize and correct imbalances in the body. Sound healing works on the belief that the human body is not solid. Rather it is energy that is held together by sound.
Any disease therefore indicates that some sound has gone out of tune.
Each color corresponds to one of the chakras in our body. Sound is used in many forms to heal and balance energies. Each chakra relates to a musical note. Equated to these tones are used for healing. I would suggest you buy a tuning fork in a local store.
