Ballad
A narrative poem or song that tells a story in short, songlike stanzas.
A ballad recounts a dramatic or tragic tale in simple, rhythmic quatrains, often with a refrain and roots in oral tradition. Writers use the form for its plainspoken momentum and folk feel, well suited to love, death, and adventure. Its regular beat makes it easy to sing and remember.
Example
Coleridge tells the mariner’s cursed voyage in rocking ballad stanzas, giving a strange supernatural tale the pull of an old sea song.
