Amphibrachic hexameter: A metrical line composed of six amphibrachic feet. An amphibrach is a three-syllable metrical foot with the pattern unstressed-stressed-unstressed (x / x). Therefore, a hexameter line of this type would contain eighteen syllables in total. While the term is technically correct, there appears to be no documented use of this specific meter in English poetry within the provided sources. It is mentioned as a potential metrical structure, likely for the purpose of illustrating the full taxonomy of possible metrical combinations. The existence of such a term shows how prosodic theory can catalog all conceivable permutations of metrical feet, even those that have never been practically applied in a major work. This contrasts with more common meters like iambic pentameter or anapestic tetrameter, which have proven their utility and aesthetic appeal over centuries of use. The amphibrachic hexameter remains a theoretical construct within the study of poetry.

Six-foot amphibrachic line (rare). Creates sustained rolling rhythm: da-DUM-da pattern eighteen syllables. Related to amphibrachic tetrameter (more common) and dactylic hexameter. Experimental rather than traditional English meter.
