If you are a musician you will be familiar with the "cycle of fifths". If not it doesn't matter, you will enjoy the songs that use that form. Much of the music of the vaudevill era played out of multiple chords in a given key.
Here's a classic example,
Edith Wilson ~ "Why Do You Do Me Like You Do?"
And if you liked Edith's style here's another song,
"Rules and Regulations"
And here's a little Fats Waller with his Ragtime piano:
"How Can You Face Me"
And some classic Ragtime guitar from Blind Willie McTell:
The paradox of Ragtime was that it superimposed often sad lyrics on an upbeat, toe-tapping rhythm. This was the basis for Piedmont Blues. Delta Blues had a very different feel.
Robert Johnson is an icon of the Mississippi Delta sound.
The Crossroads is perhaps the best example of that style:
The Big Band era turned the blues sound into a rich texture with the help of giants like Billie Holiday.
Billie Holiday ~ "God Bless the Child That's Got His Own"
Somehow all of those sounds are connected.
I'm just a player, not sophisticated enough in music theory to explain the transition from Blues to Jazz, or explain the many faces of Jazz. I just know I like all of it.
And I just couldn't resist throwing this tidbit in from the Bagdad Cafe movie
