The Eolian Harp" is a lyric poem comprised of 64 lines. Coleridge divided his poem into five stanzas, and the meter throughout is regular iambic pentameter. The term iambic pentameter refers to lines composed of five iambs. An iamb is a metrical "foot" made up of an unstressed syllable followed by a stressed syllable. As with his other conversation poems, Coleridge did not employ a rhyme scheme in "The Eolian Harp." Literary critics call iambic pentameter lines that do not rhyme blank verse.
