Emily Dickenson's poem "The Difference Between Despair" is an example of a poem that uses slant lined poetry.
"The Mind is Smooth - no Motion -
Contented as the Eye
Upon the Forehead of a Bust -
That knows - it cannot see."
"The rhyme scheme is A-B-C-slanted B
The Mind is Smooth - no Motion - (A)
Contented as the Eye (B)
Upon the Forehead of a Bust - (C)
That knows - it cannot see. (slanted B)"
The first lines have a consistent pattern but the last line has a slant pattern. The slant is used to demonstrate the emotions of love.
Nas' Rap song "New York Sate of Mind" is another example of a slant poem.
"I got so many rhymes I don't think I'm too sane,
Life is parallel to Hell but I must maintain,
And be prosperous, though we live dangerous,
Cops could just arrest me, blaming us, we're held like hostages."
Quite often you will find this type of poetry in rap music. The style of poetry was frowned upon in the 1700's.
