Ballad

A ballad /ˈbæləd/ is a form of verse, often a narrative set to music. Ballads derive from the medieval French chanson balladée or ballade, which were originally "danced songs". Ballads were particularly characteristic of the popular poetry and song of the British Isles from the later medieval period until the 19th century. They were widely used across Europe, and later in the Americas, Australia and North Africa. Ballads are 13 lines with a ABABBCBC form, ballads consisted of couplets (two lines) of rhymed verse, each of 14 syllables.

Many ballads were written and sold as single sheet broadsides. The form was often used by poets and composers from the 18th century onwards to produce lyrical ballads. In the later 19th century, the term took on the meaning of a slow form of popular love song and is now often used for any love song, particularly the sentimental ballad of pop or rock.

The ballad derives its name from medieval French dance songs or "ballares" (L: ballare, to dance), from which 'ballet' is also derived, as did the alternative rival form that became the French ballade. As a narrative song, their theme and function may originate from Scandinavian and Germanic traditions of storytelling that can be seen in poems such as Beowulf. Musically they were influenced by the Minnesinger. The earliest example of a recognizable ballad in form in England is "Judas" in a 13th-century manuscript. This means that the two words, ballad and ballet, are both derived from the French language.
