[http://www.lmsoft.com/] Science knows that music can harm or help you. The Journal of the American Medical Association recently published a study where fifty male surgeons, aged 31 to 61 worked while listening to calming, beautiful music. The result: the surgeons had lower blood pressure, a slower heart rate and performed mental tasks more accurately and more quickly. However, rock music tells a different story. At Louisiana State University researchers found that listening to hard-driving rock music increased the heart rates as well as lowered the quality of physical workouts in a group of 24 young adults. When calming music was played, their heart rates lowered which allowed for longer training sessions. Another study on the effects of rock music at Temple University found that students who listened to music by Jimi Hendrix, the Rolling Stones, Led Zeppelin and other similar bands had an increased heart rate, breathed faster and showed reduced skin resistance to stimuli compared to those who did not. At the University of Washington, researchers tested three large groups of people in their work environments and found that those who listened to calming, high frequency music increased productivity by 21.3 percent. However, the people listening to a popular commercial radio station only improved by 2.4 percent, and those working in silence decreased their performance by 8.3 percent. AT&T and DuPont have cut training time in half with similar music programs. And Equitable Life Insurance increased output of transcribers by 17 percent after introducing nourishing music to the office for a six-week period. At Kingston University in Ontario, Canada, patients who were about to undergo very painful operations were exposed to only 15 minutes of calming music. The result: they required only 50 percent of recommended doses of anesthetic drugs and sedatives.

Les scientifiques croient de nos jours que l'écoute et l'expression musicale sont aussi indispensables à l'homme que la parole. Que la musique, bien au-delà du phénomène culturel, est l'expression d'un besoin physiologique et psychologique. En musicothérapie, la musique peut stimuler l'énergie créative, aider à développer la concentration et la mémoire, et même faire surgir des émotions parfois oubliées ou profondément enfouies. La musique adoucit les moeurs, dit-on, que ce soit en jouant d'un instrument, en chantonnant, en écoutant sa musique favorite ou en tapant du pied et des mains. S'entourer de musique est certes un puissant remède contre la déprime, à la condition de ne pas jouer la carte de la mélancolie, bien sûr. (Journal de Montréal, 11 novembre 2006)
