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 later medieval period until the 19th century.
The core structure for a ballad is a quatrain, written in either abcb or abab rhyme schemes. The first and third lines are iambic tetrameter, with four beats per line; the second and fourth lines are in trimeter, with three beats per line. … Don’t worry about beats per line, rhyme schemes, or stanza breaks.
A ballad with lyrics traditionally follows a pattern of rhymed quatrains. This means that for every four-line grouping, either the first and third line will rhyme or the second and fourth lines will rhyme. The final word of the second line (“lance”) rhymes with the final word of the fourth line (“pants”).
