    When you're feeling down, the right song can make you smile. It can also calm you down when you're worried. Music may also help make your brain work better. It may even help keep you healthy.

    Why does music have these powers? It may be because people's bodies have natural rhythms (节奏). Different kinds of music can influence you in different ways.

Most stores play soft music, because soft music can make people relaxed and stay longer in a shop. And the longer shoppers stay in a store, the more things they buy in it. So, stores try to play soft music to make people buy more things.

    For sick people, music can do more than just help them relax. It may help make them get well again. Doctors believe that music is just as important as medicine in treating (治疗)patients.

    When you're sick, try to listen to the soft and relaxing music. If you're upset, play a favorite song and tell someone how it makes you feel. A group of sad teenagers shared their favorite songs with each other. Each teen explained why he or she liked the song. After talking about it, the teenagers said they felt better.

    Many studies have tried to explain how music affects learning. Don Campbell, an expert on the powers of music, believes music can make people, even babies, smarter, healthier and happier.

    Campbell wrote the book The Mozart Effect in 1997. However, not everyone believes the Mozart Effect. And people believe more research is needed to prove that music has these effects.
