Gwawdodyns are Welsh metrical stanzas used in traditional cynghanedd poetry, usually within longer awdl poems. The exact pattern can vary in historical sources, so the term is best understood as a named Welsh stanza form rather than a single fixed rhyme scheme in modern English poetry study.
Example
Ar the hill the harp wind sings,
Stone to stone the echo clings;
Bright above the bracken floor,
Night remembers every door.
