What is the author's style in Go Down, Moses ?

"Go Down, Moses" belongs to a class of spirituals that use the African "call-and-response chant form." Mr. Work describes it as "interesting as well as distinctive. Its feature is a melodic fragment sung repeatedly by the chorus as an answer to the challenging lines of the leader which usually change." In this version the chorus, "Let my people go," repeats every second and fourth line in stanzas two and three and as the last line in stanza one. It is meant to be sung by a group in answer to an individual voice that sings the first and third lines of each stanza. This repetition not only provides structure for the song, it also enables the lyrics to be easily remembered. Another aid to memory exists in the rhymes that occur at the end of the first and third lines in stanzas two and three: "land" with "stand," and "said" with "dead." The last two lines of stanza one also end with rhymes: "Pharaoh" and "go."
