When Claire Oppert plays the cello, miracles happen. Children with profound autism, patients in extreme pain and distress, even people on the threshold of death smile, cry, laugh, sing and dance. “When you play, I’m not sick anymore,” one man tells her. “I feel happy, I feel alive.” In , Oppert recounts her remarkable story of healing suffering through music, alongside portraits of the many people she has helped. Born into a family of doctors and artists, Oppert trained as a classical cellist and began playing at a center for autistic youth, where she witnessed how music could connect with even the most difficult-to-reach patients. Later, she began working as an art therapist with people with neurodegenerative diseases and palliative care patients, eventually conducting clinical trials that proved the effect of her “Schubert treatment”: using music as a counter-stimulation to reduce pain and anxiety during stressful procedures. Oppert’s crystalline, lyrical vignettes of the patients whose lives she has touched are punctuated with anecdotes from her own life as a musician, as well as reflections on the meaning of art and the human need for connection and creativity. Compassionate, uplifting, and deeply humane, is a testament to the incredible power of music to heal our bodies, minds, and souls.
