What Is a Refrain? The Line That Comes Back and Means Something Different

The words do not change and the context does, so a refrain returning after a verse is heard against everything the verse established. That is the device's central effect and it is available in no other form. A line that sounded neutral becomes ironic, a line that sounded hopeful becomes bitter, or a statement acquires weight through accumulation as each repetition adds the cases preceding it. Songs and poems exploit that deliberately, structuring the verses so that each one changes what the returning line means, and the strongest examples are unbearable by the final repetition precisely because the words have not moved while everything around them has. The device also performs practical work, since it gives a listener something to anticipate and something to join in with, marks the boundaries between sections audibly, and provides a memory anchor in oral transmission, which is why the earliest songs and ballads use it heavily.

Several terms describe recurring material and they are not interchangeable:

• •Refrain, a line or short phrase recurring at a fixed position, generally at the end of each verse
• •Chorus, a longer complete section with its own melody, recurring between verses, which is the dominant structure in modern popular song
• •Burden, an older term for a refrain sung by everyone, frequently with nonsense syllables, which is the origin of many folk song choruses
• •Hook, the most memorable element of a song, which may be the chorus, a riff, a phrase or a production detail, and which is a commercial category rather than a structural one
• •Villanelle and other fixed poetic forms, which prescribe exactly where two refrains recur across nineteen lines, producing an obsessive returning quality
• •Ritornello in baroque music, a recurring instrumental section between solo passages, which is the same principle applied without words

Popular song shifted from verse-and-refrain structures towards verse-and-chorus during the twentieth century, and the reasons are commercial and technological as much as artistic. A chorus is longer and carries its own melody, which makes it more memorable and more distinctive, which matters when songs compete for attention on radio. Recording imposed a duration, and a three-minute structure with a chorus appearing early and repeatedly suits it. The rise of the single made the immediately identifiable section commercially central. Structures evolved further, with the pre-chorus appearing as a device to build towards the chorus and the practice of starting a song with the chorus becoming common as attention spans for streaming were considered. Verse-and-refrain survives in folk, in country and in genres where narrative matters, since a long story needs verses and a short returning line rather than a large section interrupting every ninety seconds.

A great many traditional refrains consist partly or entirely of syllables carrying no meaning, and the pattern is worldwide rather than a quirk of one tradition. Several explanations are offered and they are not exclusive. Meaningless syllables are easy to sing and easy to join, which matters when a refrain is for a crowd that has not rehearsed. They carry rhythm and vocal colour without requiring the singer to track sense, which lets the voice be used as an instrument. Some are worn-down remnants of older words or of a language the singers no longer spoke, which has been demonstrated for particular cases and asserted more widely than the evidence supports. Some are deliberately meaningless to avoid saying something, whether for reasons of taboo or of secrecy. And in work songs the syllables mark the moment of collective effort, so the refrain coordinates a pull or a strike rather than expressing anything, which is the clearest case of function without content.

The structure is not confined to song. Political speech uses anaphora, meaning a phrase repeated at the start of successive statements, to the same accumulating effect, and the most quoted passages of twentieth-century oratory are built on it. Liturgy uses responses, where a congregation repeats a fixed line after variable text, which is a refrain performing a participatory function. Advertising uses slogans repeated across a campaign for recognition. Protest chants are refrains built for a crowd to sustain without rehearsal. Children's stories repeat a line that a listener learns to say along with the reader, which is both a pleasure and a teaching device. In each case the mechanism is the same: a fixed element makes variable material easier to follow, invites participation, and gathers meaning as it recurs, which is a remarkably large amount of work for one repeated line to do.

The words stay the same and the context does not, so each return carries a changed meaning, which is the effect the device exists for and which no other structure supplies. It also marks section boundaries, invites participation and anchors memory in oral transmission. The chorus displaced it in popular song because a longer section with its own melody is more distinctive on the radio.
