So he and researcher Joseph Ruszkowski set up a study in the summer of 2005. Over a period of several months, they measured the vital signs of over 200 patients before they were taken to the operating room.

After 115 of the patients were moved into the O.R, Dr. Camara played classical music for them.

"So instead of lying there and listening to operating room noise, you know leads being put on them, the clanging of the instruments as they were coming out of sterilization, the steely eyes of the nurse as they look down on them, they heard me playing for them," said Dr. Camara.

A control group of 88 patients heard no music after they arrived in the O.R. when the vital signs of both groups were measured after ten minutes in the operating room the results showed that the blood pressure of the patients who listened to the music was 21 percent lower than the patients who didn't.

Moreover, the heart rates of the those patients were 8 percent lower and their breathing rates 20 percent lower than patients who heard nothing but operating room noise.

Two of Dr. Camara's patients who described themselves as really anxious about surgery say the music really helped them.

"When the doors opened I heard this beautiful music coming out and my fears are gone, totally," said Charnette Hoke.

"It just really was the most soothing thing imaginable, I felt an elevated sense of confidence as well simply because I could hear his relaxing as well," said Laurie Mckeon.
