Refrain: A refrain is a section of a song that is repeated at various points throughout the composition, often at the end of each verse or chorus. Refrains are often distinguished from choruses by their lack of a distinct melodic and chordal pattern, as well as by their placement within the song structure.
Here is a simplified diagram of a song with verses and refrains:
Intro
Verse 1
Chorus
Verse 2
Chorus
Refrain
Bridge
Chorus
Refrain
Outro
In this example, the verses (Verse 1 and Verse 2) are distinct sections of the song with their own unique melodies and chord progressions. The chorus is a repeated section that occurs after each verse, and it provides a contrasting melodic and lyrical element. The refrain is a short, repeated section that occurs at the end of the chorus and bridge.
The verse-refrain structure is a common form of song structure, but there are many variations. Some songs may have multiple verses and refrains, while others may omit the refrain altogether. Additionally, the order of the sections can vary, and some songs may include other sections such as bridges, intros, and outros.
