How important is music? When they are asked this question, students and parents usually answer that music is nice, but not very important. It is often considered only as fun, but not the first choice for education. This opinion is shortsighted(短视的). In fact, music education is necessary and important for all students.
Music tells us who we are. Music shows people’s thinking and values, as well as the social environment it came from. just as Mozart music is a lifestyle, rock music is also a lifestyle.
Music provides a kind of ability to know the world in a different way. Science explains how the sun rises and sets. Music studies the emotive(情感的) meanings. We need every possible way to discover and respond(回应) to our world because no one way can get it all.
Music is a form of thought, as powerful as science. It is a way we human beings “talk” to each other. Through the language we express our feelings, our discoveries, our ideas and our hopes so that they can be shared with others. When we do not let our children receive good music education, we take away from them the meanings that music expresses. Science does not tell us what it means to be human. Music does.
So music education is much more necessary than people generally realize.
