Sorry I meant that jazz didn't came out of nowhere.
It has several influences which one of them is classical music.
And at first it was a popular music to dance on.
So yes jazz is jazz but you can consider it from more than one angle.

Well, all music is a combination of influences from a bunch of different genres, really. One of the best examinations of the historical musical influences of jazz, in my opinion, is James Lincoln Collier's The Making of Jazz.

Unfortunately it doesn't appear to be available to read online, but you can buy a copy, either hardcover or paperback, for 1 cent plus shipping on Amazon.

Thanks for the book, it seems interesting !

Uh, no, jazz is not classical music.

This is true.

Is birdsong music?

Birdsong is Jazz

Jazz is Bluegrass

Bluegrass is Classical..... hope this clears things up for everyone.

Thanks, Hypocrisy. I'll sleep easy now that's settled.

Technically bluegrass does have a bit of jazz in it. And birds are the founders of every genre movement, obviously.

Birdsong is music
Jazz is hip hop
Hip hop is ragtime
