Music has historically been associated with health and healing in cultures around the world. As a therapeutic intervention in patients with cancer, it is used to address physical and psychological symptoms. The sessions are tailored to meet patients’ individual needs and abilities and can involve listening to, writing, performing, or discussing music and lyrics, guided by a trained therapist. Although music does not affect the disease itself, it produces more immediate effects compared to pharmacologic agents, has a positive impact on mood, and strengthens patients’ ability to cope.
