Sound can affect the body on a cellular level because the body is made up of 70% water, and sound vibrations can travel through water so well, as well as change the molecular structure of it. Each atom of our body holds its own vibrational frequency and sound can help to restore balance when these frequencies are disturbed or thrown off due to internal or external factors, which can prevent ill health or disease. This has been shown in the autonomic, immune and endocrine systems for example, sound can affect the heart and the pulse, being able to steady or slow the heart rate as well as cause it to increase. It can also help to initiate a relaxation response in the body and mind by activating the rest and digest functions of the body through the parasympathetic nervous system, switching off fight flight or freeze responses that can cause anxiety and poor immune system functions as well as a number of stress related physical issues.

Sound can also balance and bring harmony to the body, mind and spirit. Spiritually it can help us to clear away stagnant and unhealthy energy and replace it or transmute it with positive and fresh vibrations. It can also affect our subtle bodies, also known as auric energy fields, such as the etheric, astral - which include the mental and emotional bodies - and the causal body which is also referred to as the soul. Disease and illness manifests in these layers of the subtle bodies first, as they interpenetrate each other and are linked to the physical body through the chakras and meridians, which is how illness then shows up in the physical body. Vibrations of therapeutic sound can help bring these layers to become balanced by shifting blockages and allowing energy to flow better, therefore allowing healing in the emotional and mental bodies and on a soulful and spiritual level as well as the physical.
