Quotations
As a race, negroes sing well and dance well, but they have made no distinct contribution to the play-life of nations. It is a matter of no little significance that the negro, while he has been singing his own melodies into the heats of all nations, has yet no folk-games, no race, pageants, no adequate rhythmic movements to accompany his own music. His games are pitiful imitations. The dance, to the degree he has racialized it, is not among the achievements he is proud to claim.
