I noted one potential error (lol).
I caught a show of the history of music styles and it made an interesting claim. The term Jazz was originaly a catch all for all musics that did not fall under orchestra or opera, basicaly all local musics and variations. Accounts for the term 'all that jazz'.
So if I apply it to that flowchart jazz would have been used for all of the pre 1900 stlyes until it came into its' own. And if I can paraphraze an old blues man who when asked what jazz was he clarified the blacks did not bring the blues to america, they lived them, what the brought was rythem....jazz music is what happened when a white guy tryed to play rythem
Other great music observations he made included:
1) To be a blues player you need a three word name including a body part.
2) Def: of the Blues - I've got a problem, what am I going to do about it. Caught my baby cheating, gonna shoot her dead
