I still don't understand the tone of the poem 'Harlem'. I went through all the links but couldn't figure it out...can i please get an explanation?

If you know nothing about the poet, then the poem might not make sense. Read about Langston Hughes:

and

MC -- did you look at the particular words I suggested....

I think the tone of this poem shows frustration as it describes the white opression of blacks in America.

Frustration is a good place to start.

I think discouragement... "heavy load"
also anger "explode".

The author’s attitude, stated or implied, toward a subject. Some possible attitudes are pessimism, optimism, earnestness, seriousness, bitterness, humorous, and joyful. An author’s tone can be revealed through choice of words and details.

I see frustration as the tone. Tone is not revealed so much as what the poem describes, but in the word usage, and how it is described. Remember in sarcasm, the tone is a second layer of the words used. So I agree with your, the tone is frustration.

Thank you guys (:

Definitely anger!!
