Hello GUEST,Suibhne Astray,
So, really I was asking what term you would use to describe folk music and your answer seems to imply Folk Music, so fair enough.
Now, on a different tack, your comment: The example I might give is When The Saints Go Marching In. On YouTube you can watch a non-folk rendition by the old hoarse-whisperer himself (Louis Armstrong) which is Black Classical Music, as virtuosic and intricate as any Vivaldi sonata
I find that patronising in the extreme. You seem to be saying "Look! These Blacks can somehow occasionally be as good as us!". I hugely doubt that you consider yourself a racist person, but for me, this school of thought (and I've heard it many times in different places) that somehow a strand of "black" music has scrambled to be the "equal" to what many would consider the most high-brow "white" music is the equivalent of saying "Oh, look at old Uncle Tom! He can read now as well as a white man! Well done boy!"
I'm sure you didn't mean it like that but really. It's got NOTHING to do with white classical music.
