They say that history repeats itself. It has to. Because no-one ever listens.
That was, of course, a clever line from a poem by Steve Turner from his Nice and Nasty collection. But repetition is also a poetic device. In songs it's known as a refrain. A line or a whole chorus is repeated throughout the song, mainly to carry the hook line, but also to emphasise a phrase or a key point. In poetry the latter is always a good reason to repeat a line.
There are a variety of fixed form poems that build a repetition of selected lines into their structure. The Villanelle is one example; another is the Pantoum. In both, the refrain shapes the rhythm and tempo of the poem, but can also emphasise and drive home the message the poet wishes to convey. In rhetorical poetry and prose this is known as anaphora.
Dog by Lawrence Ferlinghetti is a poem written from the perspective of the poet's dog. The poem appears simplistic at first but as you read it you quickly realise it is deeply philosophical, and the repeated lines begin to hammer home the message that the poem is really about us and our own inner dialogues.
The dog trots freely in the street
and sees reality
and the things he sees
are bigger than himself
...
The dog trots freely thru the street
and the things he sees
are smaller than himself
...
The dog trots freely in the street
and has his own dog’s life to live ...

Another type of repetition is known as epistrophe, where the same line is repeated at the end of an entire stanza or multiple lines. Again, this can be used effectively for emphasis, but can also be used to maintain the tempo of the poem. For a great example of this, watch the Bard of Salford, John Cooper Clarke performing his excellent poem Beasley Street (this version has a music backing).
Building repetition and refrains into your poetry takes a little effort, especially if you want it to make sense. But with a little effort and some practice it can become second nature. Quite a few of my own poemw draw to some extent on repetitive lines and rhythmic use of words. Try it. It's a lot of fun. (I said try it. It's a lot of fun).
