The key elements of poetry include rhythm, meter, stanza, rhyme, rhyme scheme, theme, symbolism, and imagery. Rhythm refers to the stressed and unstressed syllables that create musicality. Meter is the basic structural pattern of syllables in each line. A poem is organized into stanzas of lines that have a consistent meter or rhyme pattern. Rhyme is the repetition of similar sounds within the poem. The rhyme scheme establishes the pattern of rhyming lines. A poem's theme conveys its central idea. Symbolism and imagery allow poets to represent ideas in a non-direct manner that engages the senses.
