Pop and Rock Ballads. The term ballad is used in modern music to express an âemotional love songâ. A rock ballad is a modern song in which the word ballad appears in the title of a song, for example in âThe Ballad of John and Yokoâ by The Beatles and âThe Ballad of Billy the Kidâ by Billy Joel.
Common traits of the ballad are that (a) the beginning is often abrupt, (b) the story is told through dialogue and action (c) the language is simple or folksy, (d) the theme is often tragic--though comic ballads do exist, and (e) the ballad contains a refrain repeated several times.
