Bref double

A bref double is a formal French poetic structure consisting of three quatrains and a final couplet for a total of fourteen lines, making it the first cousin to both the sonnet and the rondel prime.

The form includes three rhymes in nine or ten of its lines, meaning that four or five lines do not rhyme. As with the sonnet, multiple rhyme schemes for the bref double have been proposed and written, including:


 * a-x-b-c x-a-x-c a-x-a-b a-b
 * a-x-b-c x-a-x-c b-x-x-c a-b
 * a-x-x-b c-x-x-b a-c-x-b a-c
