(Cuh-hée-dedd heer or cuh-huh’-death here) A form
based on syllabic quatrains. It is a Welsh form with three mono-rhymed lines of five syllables and a four-syllable rhyme that carries the main rhyme across
stanzas. The quatrains are grouped into octaves or more. The b rhyme carries through in the larger groupings, so a poem in octaves would have this sort of
rhyme scheme: aaabcccb dddefffe. The fourth line rhymes are the main rhymes. The long-line rhymes may be a little further off using alliteration or
consonance.
The quatrains can be presented as one long nineteen-syllable line. |
