I really like this post from Matt Wood at Science Life exploring the similarities (and marked differences) between musicians and physicians:
Ves Dimov, MD, assistant professor, allergist and immunologist at the University of Chicago Medicine, thinks so. "There are quite a lot of similarities between performing musicians and doctors," he says. "The audience - your patient - takes part. You have to engage them and provide answers to their questions, a correct diagnosis and treatment that works."
The entry is a response to an article in the Annals of Internal Medicine titled, "Music Lessons: What Musicians Can Teach Doctors (and Other Health Professionals)."
