Pantoum Poetry

Pantoum
The pantoum is a specific rhyme pattern of quatrains, or four-line stanzas.  The same lines are repeated several times in different positions; the first and third lines of one stanza are the second and fourth lines of the next stanza.  Traditionally, lines two and four of the last stanza are the same as lines three and one of the first stanza, so that the first and last lines of the overall poem are the same.  It can be difficult to use the exact same lines again and again and still have the poem make sense, so poets frequently alter the lines a little as needed in the different positions.
The pantoum was derived from an Indonesian/Persian song form (which is why it uses repetition so much) and introduced to Western writers by French poet Victor Hugo in the 1800s. 

At a Bus Stop

Ideas are rolling about in my head
like spare change in my pocket
as I sit here at this bus stop
waiting for the 8:15 into the city.

Like spare change in my pocket
people mill about
waiting for the 8:15 into the city
at this dim cement junction.

People mill about
and I make up a name for each lovely face
at this dim cement junction
where moss grows on the walls.

And I make up a name for each lovely face
as I sit here at this bus stop
where moss grows on the walls
waiting for the 8:15 into the city.
