A Musician Who Performs With a Scalpel

For Claudius Conrad, a 30-year-old surgeon who has played the piano seriously since he was 5, music and medicine are entwined — from the academic realm down to the level of the fine-fingered dexterity required at the piano bench and the operating table.

Like many surgeons, Dr. Conrad says he works better when he listens to music. And he cites studies, including some of his own, showing that music is helpful to patients as well — bringing relaxation and reducing blood pressure, heart rate, stress hormones, pain and the need for pain medication.

But to the extent that music heals, how does it heal? The physiological pathways responsible have remained obscure, and the search for an underlying mechanism has moved slowly.

Now Dr. Conrad is trying to change that.

He recently published a provocative paper suggesting that music may exert healing and sedative effects partly through a paradoxical stimulation of a growth hormone generally associated with stress rather than healing.
