A ballad is a form of verse, often a narrative set to music. Ballads derive from the medieval French chanson balladée or ballade, which were originally "dance songs". Ballads were particularly characteristic of the popular poetry and song of Britain and Ireland from the Late Middle Ages until the 19th century. They were widely used across Europe, and later in Australia, North Africa, North America and South America.

A quatrain is a type of stanza, or a complete poem, consisting of four lines.
