"I Hear America Singing" by Walt Whitman

I hear America singing, the changed hymns I hear,

Those of mechanics, every one singing his as it ought to be merry and solid,

The woodworker singing his as he gauges his board or pillar,

The bricklayer singing his as he prepares for work, or leaves off work,

5 The boatman singing what has a place with him in his vessel, the deckhand singing on the steamer deck, The shoemaker singing as he sits on his seat, the hatter singing as he stands,

The woodcutter's tune, the plowboy's on his way toward the beginning of the day, or around early afternoon break or at nightfall.

The heavenly singing of the mother, or of the youthful spouse at work, or of the young lady sewing or washing, Each singing what has a place with that person and to none else.

10 The day what has a place with the day—around evening time the gathering of youthful colleagues, powerful, inviting, Singing with open mouths their solid musical tunes.
