refrain

v. abstain, forebear, restrain oneself, desist

n. verse or phrase that is repeated during a song or poem, chorus; music or melody that accompanies the chorus

A refrain (from the Old French refraindre "to repeat," likely from Vulgar Latin refringere) is the line or lines that are repeated in music or in verse; the "chorus" of a song.  Poetic fixed forms that feature refrains include the villanelle, the virelay, and the sestina.The use of refrains is particularly associated with popular music, especially rock and roll, where the verse-chorus-verse song structure typically places a refrain in almost every song. The refrain or chorus often sharply contrasts the verse melodically, rhythmically, and harmonically, and assumes a higher level of dynamics and activity, often with added instrumentation. Chorus form, or strophic form, is a sectional and/or additive way of structuring a piece of music based on the repetition of one formal section or block played repeatedly. See also verse-chorus form.
