The chorus Breath Strati aims to create a transformation of sound similar to the movement of air or mist, by using the high-pitched, delicate overtone of women's voices. There is no score for this music, but its structure is based on a simple rule: the timeline is built according to the different natural lengths of human breath. Thus anybody can participate and a new "living music" is born every time, depending on the characteristics of each participating body. Each person listens to the others' change, and the voices resonate; it is music like meditation or prayer.
