When Wolfgang Amadeus Mozart was a child, people were amazed by his musical ability. He could play instruments, compose music and remember complicated pieces. One of the most famous stories happened when Mozart was just 14 years old. He visited Rome and heard a very special piece of music called Miserere being performed in the Sistine Chapel. The music was not supposed to be copied. But Mozart listened carefully — and later wrote down the music from memory. The story may have become a little bigger over the years, but Mozart really did have an extraordinary musical memory. He could hear music in his head and remember it in incredible detail.
