The poet hears the "varied carols" of all the people who contribute to the life and culture of America. The mechanic, the carpenter, the mason, the boatman, the shoemaker, and the woodcutter all join in the chorus of the nation. The singing of the mother, the wife, and the girl at work expresses their joy and their feeling of fruition. These are highly individualistic men and women. Each person sings "what belongs to him or her and to none else."
This poem underscores Whitman's basic attitude toward America, which is part of his ideal of human life. The American nation has based its faith on the creativeness of labor, which Whitman glorifies in this poem. The catalog of craftsmen covers not only the length and breadth of the American continent but also the large and varied field of American achievement. This poem expresses Whitman's love of America — its vitality, variety, and the massive achievement which is the outcome of the creative endeavor of all its people. It also illustrates Whitman's technique of using catalogs consisting of a list of people.
