M.Ted is quite correct about the formal training enjoyed by the early black composers. While the intent of their training was, no doubt, for sacred music, we owe, virtually, all American popular music to their creativity and their ability to blend Eurocentric and Afrocentric musical traditions. This point brings us back to the original question, why are some traditions seem as "folkier" than others. If Elizabeth Cotton is folk, why aren't Louis Armstrong or Jellyroll Morton? (Of course, we know why. It's that guitar thing. If Mississippi John played piano, he would be a jazz icon)
