Who are the "singers" in Walt Whitman’s poem "I Hear America Singing"?

Those who “sing” in Whitman’s poems are those who are the defining elements of the basis in America.  Each particular part of America has a song to sing.  In this praising of America’s heterogeneous nature, each song is uniquely different from one another.  However, Whitman ensures that each voice from a different walk of life is one that will be able to contribute to the tapestry of what it means to be America.  The mechanics, the boatman, the women all provide distinct and unique voices in what it means to be America.  These voices are middle class, or regular people, whose contributions define in Whitman’s mind what it means to be American and the greatness within that essence.
