Scientists have not yet pin pointed the exact reasons that spur a hundred emotions within us when we hear music. Music does not only relieve our tension and stress it can also make us sad or emotional. Both laughter and tears are induced by music. Our brain has a tendency of attaching good and bad memories with certain songs or music as well as with some odors or place. The music directors know which musical notes will trigger an enthusiastic and happy response and which notes will make us sad and overwhelmed with grief. The science behind our response to music is still not clear.
