The Biology of Music

    Humans use music as a powerful way to communicate. It may also play an important role in love. But what is music, and how does it work its magic? Science does not yet have all  the  answers.

    What are two things that make humans different from animals?  One is language, and me other is music. It is true that some animals can sing ( and many birds sing better than a lot of people). However,the songs of animals, such as birds and whales, are very limited. It is also true that I  humans, not  animals , have  developed  musical  instruments¹.

    Music is strange stuff. It is clearly different from language. However,people can use music to   communicate  things - especially  their emotions. When  music  is combined  with  speech  in  a  song .it is  a very powerful form of communication. But,biologically  speaking , what is music?

    If music  is  truly  different from speech,then  we  should process music  and  language  in different  parts of the brain. The scientific evidence suggests that this is true.

    Sometime  people who suffer brain damage lose their ability to process langua  . However, they don"t automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian composer,had a stroke in 1953. It injured the left side of his brain. He could no longer speak or  understand speech. He could, however, still compose music until his death ten years later. On the other hand, sometimes  strokes cause people to lose their musical ability , but they can still  speak and understand speech. This shows that the brain processes music and language separately.

    By studying the physical effects of music on the body, scientists have also learned a lot about  how music influences the emotions. But why does music have such a strong effect on us? That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection Music requires special talent, practice, and physicai ability. That"s why it may be a way of showing your fitness to be someone"s mate. For examplel singing in tune or playing a musical instrument requires fine muscular control. You also need a good, memory to remember the notes. And playing or singing those notes correctly suggests that your hearing  is  in excellent condition. Finally , when a man sings to the woman he loves  ( or vice versa) ,  it may be a way of showing off.

    However , Miller"s theory  still doesn"t explain why certain combinations of sounds influence our emotions  so deeply. For scientists, this is clearly  an  area that needs further research.
