    Music is magic! Music speaks louder than words and it is a “language” that the whole world can understand. A piece of music can produce a response in the heart and mind. Like feeling an electrical current or receiving a personal radio signal, music has a spiritual effect on a person. Different kinds of music influence people in different ways.

    I have listened to music all my life. When I was twelve years old, the Beatles came to America and my whole world opened up. Maybe young people today cannot understand the influence of the Beatles when they exploded across America. Their influence changed the way we dressed, looked, acted and spoke... even our culture. The Beatles arrived in America from the UK just under three months after the assassination(暗杀) of President John Kennedy, which had put America into a great depression. And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.

    Music links the heart of the hearer with that of the composer. This means that it mixes the spirit of the composer with your spirit when you listen to it. And the music can take your spirit out of your body and transport you into another world. Music has a great way of touching people. Music can make you laugh, cry or shout. It's also a great source of inspiration.

    Try this one day and notice what happens: make yourself a cup of tea, sit on your sofa and play one of your favorite songs. Close your eyes, and soon you'll find yourself creating vivid mental images—matching the music that you are listening to.
