When reading a passage that describes a character trying to get out of an extremely dangerous situation, one would expect the author to use Suspense. When the suspense is used in the writing it is tried to maintain the expectation on a resolution or the state of tension in a certain situation. The impatient expectation of the viewer or reader is sought for the development of an action.
The speaker's tone in "Harlem" is best described as frustrated.
The poem's imagery helps to convey this tone. In discussing a deferred dream, Hughes describes a dried up raisin in the sun; a festering sore; stinking, rotting meat; and a sagging, heavy load. At the end of the poem, he wonders if the deferred dream just explodes.
This imagery helps provide the key to understanding the speaker's attitude, or tone, about his subject, the deferred dream. He is frustrated that these dreams are wasted.
