Each sound we hear in everyday life is memorized in our brain and constitutes an image. When we realize this, we understand how polluted our sonic memory is. While the harmonious union of sounds ensures the creation of a healthy mental image, it also provides healing. The first workshop of the Sound Healing series prepared and led by Sheri A Sayar aims at determining the frequencies that are most aligned to nature and to our being, all the while purifying us from the noise of city life.
