Every disease is a musical problem

“We may see very clearly how the wrong sound, or “anti-music,” is pathogenic and migrainogenic; while the right sound—proper music—is truly tranquillising, and immediately restores cerebral health. These effects are striking, and quite fundamental, and put one in mind of Novalis’s aphorism: “Every disease is a musical problem; every cure is a musical solution.” 
― Oliver Sacks
