     When students and parents are asked to rate subjects according to their importance, the arts are

unavoidably at the bottom of the list Music is nice, people seem to say, but not important. Too often it is

viewed as mere entertainment, but certainly notan education priority (优先). This view is shortsighted. In

fact, music education is beneficial and important for all students.

     Music tells us who we are. Because music is an expression of the beings who create it, it reflects their

thinking and values, as well as the social environment it came from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazzinfluence that George Gershwin and other musicians introduced

into their music is obviously American because it came from American musical traditions. Music expresses our character and values. It gives us identity as a society.

     Music provides a kind of perception (感知) that can not be acquired any other way. Science can

explain how the sun rises and sets. The arts explore the emotive (情感的) meaning of the same

phenomenon.We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.

     The arts are forms of thought as powerful in what they communicate as mathematical and scientific

symbols. They are ways we human beings "talk" to each other. They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give

children access to an important way of expressing themselves such as music, we take away from them themeanings that music expresses.

     Science and technology do not tell us what it means to be human. The arts do. Music is an important

way we express human suffering, celebration, the meaning and value of peace and love. So music

education is far more necessary than people seem to realize.
