     Shane Thomas is a 10-year-old pianist from England. He's being called the next Mozart because of

his amazing abilities.

     He has only been having piano lessons for four months, and practices four hours a week, but he has

already played difficult classical pieces. He was just seven when he sat down at the piano, and could play

at once. He also says he never gets nervous.

     When Shane was three years old, he said that he could play the piano, but nobody took him seriously.   At school, he could listen to the teacher and do his work while composing (作曲) in his head. Shame

remembers all the melodies (旋律), and when he gets home he plays them on the piano, while his father

records them. Shane loves playing the piano, and when he grows up he wants to be a composer.

in Salzburg, Austria, and was one of the most famous composers ever. Mr. Goffin-lecar says, "I don't

teach Shane very much. I just give him directions, then sit back and watch."
