This week, we have three stories about the life-changing, transformative power of sound. First, we look at brain activity during moments of silence in music. Then, a student investigates the healing powers of traditional Cambodian chants. Finally, a class of Stanford students led by John-Carlos Perea find a new community while learning the art of the powwow drum.
