Jazz is an American style of modern music.
A long time ago, many African American people wanted to play musical instruments.
However, they could not become classical musicians, because of their skin color.
They could not learn at classical music schools.
So, African Americans began to play classical music in their own style.
Now, jazz is popular all over the world.
Fly (Me) To The Moon must be one of the most famous jazz pieces.
It is played by millions of musicians.
Probably it is being played somewhere in the world right now.
