A traditional Welsh stanza form with six short lines and a fixed pattern of rhyme and syllable count. It belongs to the older strict-metre tradition, so the sound pattern and line length are controlled rather than free. Because historical descriptions can vary in detail, the form is best understood as a tightly structured Welsh verse pattern rather than a modern open stanza.
Example
Stone on the hill,
wind in the grass;
night over water,
whisper and pass;
stars in the dark,
dawn in the glass.
