Music and dance play a central role in the "healing arts" of the Senoi Temiar, a group of hunters and horticulturalists dwelling in the rainforest of peninsular Malaysia. As musicologist and anthropologist, Marina Roseman recorded and transcribed Temiar rituals, while as a member of the community she became a participant and even a patient during the course of her two—year stay. She shows how the sounds and gestures of music and dance acquire a potency that can transform thoughts, emotions, and bodies.
