• Double Rondeau is simply doubling the pattern of the Rondeau. It can either be doubled in sequence (1 Rondeau following another Rondeau) or the like stanzas could be doubled and paired.
The is:
○ A 30 line poem made up of a quintain, quartain, sixain, the same order repeated a second time or a 30 line poem made up of 2 quitains followed by 2 quatrains and ending with 2 sixains.
○ metric, iambic tetrameter accept for the refrain which is iambic dimeter.
○ All stanzas end with a rentrement.
○ rhymed using either 2 or 4 rhymes. aabba aabR aabbaR aabba aabR aabbaR or aabba aabba aabR aabR aabbaR aabbaR or aabba ccddR aabR ccdR aabbaR ccddcR or aabba aabR aabbaR ccddR ccdR ccddcR.
○ Whether the poem is turned on 2 or 4 rhymes, the rentrement would remain the half line from the first line of the poem to be consistent throughout the poem especially when it is sequential (1 Rondeau pattern following another Rondeau pattern.) There could be 2 rentraments which alternate from the 1st line of each of the 1st and 2nd quintains when the like stanzas are paired.
