What is the author's style in The Song of the Smoke by W.E.B. DuBois?

Music is of course central to the ballad. The musicality of this poem is achieved by two distinct methods. First, the lengths of the lines in each of five blocks in a stanza are similar because the rhythm of the words creates corresponding musical patterns in blocks of 2 lines, 2 lines, 3 lines, 2 lines, and 2 lines in each of the four stanzas. The rhyme scheme of abccdddeeab further establishes this musical pattern or rhythm.
