When she isn't touring the world or with her students, Claire Oppert plays cello for people at death's door, people who suffer chronic pain, people deemed autistic or mentally ill. In words both delicate and poetic, this musician recounts her one-of-a-kind encounters. Hailed and recognized by the scientific world, her medical procedure, the Schubert Treatment, relieves pain and anxiety in patients, shining a light on the power of music.
