So what does this story have to do with sound healing? It’s a simple way of looking at resonance. When we hear sound, we hear it not only with our nervous system and our brain, but those sounds resonate within us. It’s why some music can make you cry, some can make you scared, while other music can make you smile. There’s nothing in the individual notes that does that per se, but it’s the way those sounds resonate within you - both physically and emotionally - that can create different moods.
A short digression here. I just wrote “physically and emotionally”. But think about it: where do you feel your emotions? You feel them in your body - yes? Some feelings are in the pit of your stomach, while others affect your chest, and still others are felt in your throat. So while we use different terms - “physical” and “emotional” - emotions are physical in nature. They are thoughts coupled with a physical sensation. It’s tricky to remember that, when our language points to a different version of reality.
OK - so back to sound healing. We use sounds to affect us on physical as well as emotional levels. And since there’s really no separation between those two things - the body and the mind - then affecting one will affect the other. If we are depressed, for instance, we will have a depressed immune system. When we use the term “I can’t stomach that person”, we are not just speaking metaphorically. Our stomachs can “feel” our emotions, and are affected by them. The state of health of our stomach can also can affect us emotionally. So sound mind can equal sound body, and vice versa. By using sound, we can affect body and mind, which can make positive changes to both.
