Blues poetry draws on the language, rhythms, and emotional reach of the blues tradition. It often uses repeated lines, simple direct speech, and themes of hardship, endurance, love, and loss. Many blues poems echo the blues song form, especially the AAB pattern, in which one line is repeated and then answered by a third line that changes or deepens the idea.
In poetry, the blues is less a strict meter than a style shaped by voice, repetition, and musical feeling.
Example
Been workin' all day, and the sun won't fade,
Been workin' all day, and the sun won't fade,
Still I hum my sorrow till it turns to shade.
