Music not only gives you something to sing and dance to, but also can make you
feel happier. Scientists say that music can help to relax people’s mind and even help
to relieve（痛苦） pain. How does music work its magic? It is the fact that music
can adjust(调节) our mood（心情）. Recently, there is a scientific research toback up
what we have always known about music. The studies have shown that when people
are excited or happy they are more helpful. The opposite (相反的情况)happens when
people feel aggressive（好斗的） or under stress. The use of music can influence how
helpful people can be.
Dr. Adrian North made a study with 256 university students.Half the group took exercise
in the gymnasium listening to music which can bring happiness and the other half exercised
to aggressive music. When leaving the gym, the students were asked to hand out flyers（传单） in support of the local disabled athlete’s foundation（残疾运动员基金会）.
The results showed that nearly half of the group that listened to happy music were willing to (愿意) hand out flyers. But less than 20% in the group that heard the aggressive music were willing to do so. This study suggests that our choice of music can influence our willingness to cooperate(合作). While a study also shows that productivity (生产效率) can be increased with the right choice of background music in the workplace. As music stimulates(刺激)worker’s mind, job satisfaction is often positively influenced. Other studies have shown that workers who are in a good mood have more job satisfaction than those in a bad mood.
These studies show that music can have a powerful influence on a person’s ability to cooperate. Moods have a direct influence(直接影响) on cooperation and job satisfaction. These factors also have a direct relationship to the success of a business.
