A study at New Jersey’s Morristown Memorial Hospital, where a harpist strolls the recovery room, is looking into the effectiveness of harp music as a healing aid for heart-surgery patients. Researchers believe “the gentle arpeggios of the harpist might have helped regulate … heart rate, blood pressure and breathing…. Results will be collected as part of a four-week study, one of several around the country trying to measure the health benefits of music in hospitals. One research project by a doctor at the Carle Heart Center in Urbana, Ill., has suggested that harp music in particular helped stabilize irregular heartbeats.”
