The poetry of Langston Hughes tends to be almost deceptively simple in style. If you look at some of his best-known poems—"Harlem, "Jukebox Love Song," "April Rain Song," or "Dreams"—you see that he does not use words that are difficult to understand. His poetry is incredibly accessible in this way: he isn't writing for elites, for those who expect adherence to traditional notions of what poetry "ought" to be.
Hughes creates not only beauty but also intense messages with his poems. He ignores classical forms, instead using jazz and that musical genre's rhythms as inspiration for his poems. His poems often focus on the experiences of black people, drawing attention and importance to lives and experiences of a group that was (and still is) marginalized by white America. Therefore, his poems are also, often, vehicles of protest, written to be understood by anyone.
