Quatrain

A quatrain is a poem, or a stanza within a poem, that consists always of four lines. It is the most common of all stanza forms in European poetry. The rhyming patterns include aabb, abab, abba, abcb.

In its narrow meaning, the term is restricted to a complete poem consisting of only four lines. In its broader sense, it includes any one of many four-verse stanza forms.

The warmest day once, then a path wrapped in red and brown
Lead to the chill of snow and frost
Hope now wears a ragged frown
O' head stay held high; all is not lost ....
