Earlier quoted context omitted.
>I'm a little puzzled as you're describing a music stylist on skin colour, black vs white You may not realize this, but in the 1930-1950 era being described in America, there was something called "Segregation" where black people were considered legally inferior to white people.

You should be able to describe the sound differences if the music is that distinct.
They are and I can, however the existence of Black Swing is in no way predicated on a difference in sound only.
Consider this: white culture in America continually stole from a legally repressed black culture, including white swing which stole the black art and commercialized it. Even if a 1950 white swing song sounds similar to a 1940 black swing song, there is still a "black swing" and a "white swing".
Frankly, I think trying to reduce history of music down to "the sounds themselves" is a way to whitewash the history and destroy the true knowledge of what happened and why. The context is very important.
