A '''refrain''' (from [[Vulgar Latin]] ''refringere'', "to repeat", and later from [[Old French]] ''refraindre'') is the [[Line (poetry)|line]] or lines that are repeated in [[poetry]] or in [[music]]—the "'''chorus'''" of a [[song]]. [[Poetry|Poetic]] fixed forms that feature refrains include the [[villanelle]], the [[virelay]], and the [[sestina]].

In popular music, the refrain or chorus may contrast with the [[Verse (popular music)|verse]] [[melodically]], [[rhythmically]], and [[harmonically]]; it may assume a higher level of [[dynamics (music)|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 (rhetorical device)|repetition]] of one formal section or block played repeatedly.
