The term POETIC PATTERN refers to the structure of a poem, which is composed of two elements: METER and rhyme scheme. METER is the rhythm of a poem, usually determined by the number of syllables in each line and the pattern of stressed and unstressed syllables. Rhyme scheme is the pattern of rhymes used in a poem, usually indicated by assigning a letter of the alphabet to each rhyming sound. Together, METER and rhyme scheme create the poetic pattern of a poem.
