In the poems, I Hear America Singing and I Sit and Look Out, author Walt Whitman uses contradictory moods and themes. In I Hear America Singing, Whitman writes about different individuals in the workforce singing as they go about their work. He writes in a free verse type of poetry taking each person and describing their song. Ultimately all the songs of the working class is what makes up ‘America’s song’ also, like how the labor of all the individuals is what makes up America. Whitman gives off a joyful tone in this poem really shining the light on those in America who’s roles and work usually get overlooked. In the second poem, I Sit and Look Out, Whitman uses a drastically different mood and feeling in his writing.
