     To me, music is food and water.I can't live without it.I know this is not true for everybody.Many

people don't listen to music and they can get along quite well.But music is everywhere in our life.For

example, when you watch films or TV plays,do you find them interesting if there is no music?You

because it makes the time seem shorter.

sound of the sea.Some enjoy listening to the singing of birds.Those sounds are some kinds of music.
