Visionary singer Susan Hale believes that early peoples deliberately built their structures to enhance natural vibrations. She takes us around the globe-from Stonehenge and New Grange to Gothic cathedrals and Tibetan stupas in New Mexico-to explore the acoustics of sacred places. But, she says, you don’t have to go to the Taj Mahal: The sacred is all around us, and we are all sound chambers resonating with the One Song.
