      Chopin (肖邦) was born in March, 1810 near Warsaw (华沙) in Poland (波兰). He was one of the

greatest musicians in the world. In 1831, when he went to Paris, no people but he could play the piano

very well.

      At that time people in Paris liked the Hungarian (匈牙利) pianist liszt (李斯特). One night, at a concert,

Liszt went to the piano and all the people shouted. As all the lights in the concert were turned off, a

wonderful piano concert started. The music was so good that the listeners were all greatly interested. They

kept praising the pianist and thought that Liszt reached something new in playing the piano. 

     Suddenly, all the lights were turned on again as the music came to an end. And there stood a young man

instead of the famous Hungarian pianist Liszt. 

     Liszt planned all this. As the lights went out, Liszt left his chair and let Chopin take his place. So with
