Hospitals and doctors' offices are inviting singers and musicians to help patients manage their pain, as music's ability to reduce pain is gaining attention. No one is suggesting that a catchy song can completely eliminate serious pain. But several recent studies have suggested that listening to music can either reduce the perception of pain or enhance a person’s ability to tolerate it. The key is letting patients choose the music and encouraging active listening. Scientists say one aspect of music's power is simple distraction, but it's more than that. It changes the perception and experience of pain, and the isolation and anxiety.
