Belly Breath with Sound you produce sound when air leaving your lungs passes over your vocal cords causing them to vibrate. This vibration creates a healing environment for the body and mind. The simple sounds that are user friendly, easy to use in all languages and dialects are “ah, sa, ma, hm”. On longer exhale you can do an energizing sound “ah, sa”. Or you can do a calming sound “ma, hm”. Sound can also help you coordinate your breath and movement for example in a pose like side bends.
