A Ballad is a verse, usually having music. The word ballad derives from the French word "chanson balladée". Ballads were originally intended to be accompanied by dance. The dancers would sing the song as the musicians played. The first ballad thought to be written was "Judas" written in the 1200s.
The Ballad of Billy The Kid
By Billy Joel
‘From a town known Wheeling, Wes Virginia
Rode a boy with six gun in his hands
And his daring life crime
Made him a legend in his time
East and west of Rio Grande’
