James Weldon Johnson said this quote

American musicians, instead of investigating ragtime, attempt to ignore it, or dismiss it with a contemptuous word. But that has always been the course of scholasticism in every branch of art. Whatever new thing the 'people' like is poohpoohed; whatever is 'popular' is spoken of as not worth the while. The fact is, nothing great or enduring, especially in music, has ever sprung full-fledged and unprecedented from the brain of any master; the best that he gives to the world he gathers from the hearts of the people, and runs it through the alembic of his genius.
