|The ballad is a narrative poem, often of folk origin, that is intended to be sung. It consists of simple stanzas and usually has a recurrent refrain. The four-lined ballad stanza typically has the rhyme scheme abcb and alternates four iambic metrical feet with three iambic metrical feet. However, other rhyme schemes do occur, and perfect meter is rare.
The refrain is typically a repeated line or stanza in which a single word, termed the "burden," is changed. Another common trait is a sequence of "threes" that occurs in the verse. Often there is abundant dialog, either in first person describing the action, or in the speech of two characters occurring in alternate lines.
I sing of Saturn on this day;
Before his rule, our lives were grim;
When Saturn's work on earth was done,
We cease our toil, then offer thanks,
Not every day can be a feast;
