What role does music play in health and wellness?

Enormously important. I have personally seen how music can be extremely helpful in creating a soothing environment. Years ago when my father was on a ventilator in the ICU with a near-fatal pancreatitis, we brought in tapes of soothing music. He was oblivious, to our knowledge, but his nurses and respiratory therapists seemed to linger longer in his room, maybe providing a bit more care because of the music. Try this!
