Iambic heptameter

Iambic heptameter is a poetic meter that has seven iambic metrical feet per line. e.g. "The rusty chains of prison moons are shattered by the sun" (from King Crimson's "In the Court of the Crimson King", words of P. Sinfield) Typical in iambic meter, the stress of the foot is placed on the second syllable, longer syllable, followed by an unstressed shorter syllable. This is one of the most uncommon iambic forms, alongside trimeter. The most famous example of iambic heptameter in execution, is Philip Sidney's seventh song of Astrophel and Stella. Contrast with iambic pentameter, for instance, which is an iambic meter with five feet per line, and trochaic meter, where the longer syllable precedes the short one. full article at wikipedia
