Jazz is not Blues and Blues is not Jazz.......

'Jazz ain't Blues and Blues ain't Jass.......But I tell you what. If you cain't play the blues. You cain't play jass.' 

If we didn't have blues were sure wouldn't have jazz.

@oldhvymec,
You're on to something big bruh.

How's this, Country Western, Rock and Roll, Blues and Jazz were ALL born in the USA. They are bound to cross a few boundaries.
Wrong country for being a purest, ay?

If you think about it, one was born from the another, or branched and taken from another. It's not like Opera, Dixieland jazz, Bali, or Bagpipes, crossing lines... Just sayin, more alike than not...

The older I get the more I learn that the blues or any american music for that matter is a melting pot of all music that came before it. Even the indigenous music of the american indian had just as much effect on the creation of blues as any of the european and african music that is given more credit.

Even in New Orleans the black folks of the 1800's recognised that the indian population and people were treated even worse than the black man. And if that ain't the blues, I don't no what is.

Legend has it Charlie Patton, the so called father of Delta Mississippi blues was part Choctaw which had a profound effect on the music he was creating or should I say melting. I have learned to love Delta Mississippi music. Blues, french, spanish and indigenous indian and all. After all  Mississippi is a Choctaw word.

It also shows blues pioneer Charley Patton, an early 20th Century Mississippi Delta guitarist of Choctaw and African-American ancestry, fused Native American rhythms with black music.

Co-director Catherine Bainbridge says the film presents a missing chapter in the history of American popular music.

Let us compare the sound of the "Delta Blues" to the sound of Blues in Jazz;

Now lets listen to Blues in jazz;

All of that music is called "The Blues". Do you hear a major difference between what's called Blues in Jazz and what's called "Blues" since I can remember and even before then? Or is that the difference between "Delta Blues" and all other Blues?


This gets back to the OP's original statement, 
Jazz is not Blues and Blues is not Jazz.......

In typical fashion, threads lose focus and go off in directions that are irrelevant. There is a tendency to dig one’s heels in and miss the forest for the trees.

I don’t recall anyone here claiming that there are no important differences between Blues and Jazz; or that they should be called the same thing. To claim so would be absurd. The over simplified title of the thread is only one part of the OP’s premise and complaint. The complaint was: “why do the two get lumped together?” I think that plenty of factual data has been presented and a pretty good case made for why they do get lumped together; and rightfully so. They are musical cousins having related genetic blue prints.

I think that this tune has been beaten to death and I will leave the discussion with this thought: there is a reason that I can find my Pepper Jack cheese in the same aisle as the milk 😋 (love those food analogies!).

I do find it interesting Orpheus10, knowing how many times you have come across the phrase “No Blues, no Jazz”, that this is the first time that I have noticed your objection to the premise 🤔
