<< I agree with the topic sentence. We listen to music in various situations. In some cases we listen to music to do our works efficiently. In other situations, we just listen to music just to be relaxed. In restaurants, we can also enjoy listening to music while we have dinner. Every culture has its own classical music, and that can clearly express the characteristics of the culture. Music is important because music has variety of powers according to the situations. Some surgeons listen to their favorite music while they are doing surgical operations. Someone might think that this is not a good thing because music might lose surgeons' concentration. But surgeons listen because music has power to heat up their efficiency of works. By listenning to their favorite, rhythmical music, their hands move quickly, and their minds are even concentrated on the operation. Music surely have power to concentrate our minds and help our work efficiently done. In other situations, we listen to music just to be relaxed. For example, we listen to music while driving a car, this is not because to be concentrated on our driving. In many cases, in a way from our company we listen to music. This is because we want to be relaxed after our working of a day. We want to be healed while driving a car. But too much healing is dangerous for us because we drive a car. So I don't recommend Enya for exapmle, listenning in a car. Sometimes, in a restaurant, we can listen to music while we are eating. Especially in a high-end restaurants, we can sometimes listen to music with a real player on time. Such a music stimulate our taste, and we can have dinner more tastefully. Evey culture has its own music in their language. Those music tell us the history of the country, how our ancestors have lived in the land. Such a music connect and join our minds to be one thing. Unit our different minds and stimulate the development of our country. In this way, music have variety of roles according to the situations. Sometimes, as a stimulator of our jobs, sometimes just for drugs for relaxation. Music also have a power as a spice of foods. Spicy music stimulate our appetite and we can enjoy dinner more tastefully. Also, by listenning to music, we can feel what our ancestors feel and think. Such a music unit and stimulate our respect for our country. Music has so many roles that I can't tell all of it just in this essay. So music is important for people all around the world.
