Jazz is type of music and the only art form that was created in the United States.
Jazz was created by black Americans.
Many blacks were broght from Africa to America as slaves.
Different native songs were sung by the black slaves and the music of their homeland was played in America.
It is made up of the music of West Africa,the work songs of the slaves and religious music.
The first jazz bands were formed at the end of the 19th century.
This means that jazz music is made up or created on the spot.
This is why a jazz song can sound a little different each time it is played.
Today jazz is played all over the world.
On every continent special festivals are held where jazz muscians from the United States, Asia, Africa, South America and Europe meet and share their music.
Let's hope that no matter what happens in music jazz will always be performed and listened to.
