Music and dance have a relationship like a needle and thread. From a long time ago, human beings had lived with music and dance. People used them as a tool for ceremonies or expression of emotions. Most people live with music and dance in their common life. They need music and dance more when they are happy or sad than when they are not. In other words, music and dance is a food for human's mental condition.
　　　 Especially many Koreans like music and dance very much. For example, we can see some people who listen to music wearing earphones in the street　 or subway. Also, how many singing rooms or night clubs are there in Korea? In addition, whenever Koreans get together they sing a song and dance. Most people like someone who is good at singing a song or dancing very well. That's why, I think, music and dance are very important to us. Therefore, I'd like to talk about the correlation between humans and music and dance.
　　　 Most of all, I'd like to talk about the good influence that music and dance give to us. Nowadays many pregnant women let their babies hear good music forprenatal training. Also, when many psychiatrists treat their patients, they use music. In my case, when I don't feel well or am gloomy, I listen to music or sing a song. If so, I come to feel better. If that is the case, why dopeople happy listening to music, singing a song or dancing?Why do people feel comfort listening to music, singing a song or dancing? Because music and dance are a way of expression for humanbeings, for example, thought, appearance, image, behavior, emotion, human point of view, etc. We can represent our inner emotions through music and dance. We can feel true aspects of humanity through music and dance. That's why humans love music and dance and humans are made happy by them. Also, it is because humans make music and dance and that humans' soul is alive.
　　　 Secondly, we can experience worlds which we can't see through music and dance. For example, when we listen to Mozart or we learn dancing from a dancer, we come to feel their world. In other words, music and dance fertilize our mental condition. Because music and dance is an expression of humans' mental condition, that's why we can understand and feel their thought and emotion through music and dance although they are someone who I never don't know.
　　　 Finally music and dance will be a part of humans' lives as long as human beings live in our universe. In that way, music and dance are like a mirror, because, as mentioned above, music and dance are a part of the human soul and contains ourselves. I hope that our world will be happy, and all of us will love each other like beautiful music and dance. I hope that many people will be happy like a happy song.
