==Sound of Nature==
The sound of fire, water, earth and air provides an ideal setting for releasing trauma, sickness and pain. Also the voice can be used to heal in a natural setting. Reconnecting deeply with nature can create a 'sense of belonging' and 'coming home' and sound can readily enhance and enrich this process.
