"I Hear America Singing" uses the symbol of different songs to represent the pride and accomplishment of the varied American population.
The language in the poem is very simple and straightforward. Whitman doesn't concern himself with rhythm or rhyme; his message lies in expressing the joy in work and life that is felt by the people he describes and the activities with which they are engaged. He is recognizing the independence of ownership, the pride of work done well, the fulfillment of accomplishing a good day's work by working with your hands and using your abilities to the fullest.
The carpenter...as he measures his plank or beam,...The boatman singing what belongs to him in his boat-the deckhand singing on the steamboat deck
As with all of the poems in Leaves of Grass, "I Hear America Singing" is a celebration of the American common man, woman and child.
