A few years back I invented (or I think I did) the julain: A three-line poem of a set meter with the rhyme scheme xaa.
I have seen double julains of abb acc. And I’ve seen double julains of xaa xbb.
Today, I saw that someone on pffa had invented the julainnelle, a villanelle variation that uses julains for the individual stanzas: AbB baA abB bbA abB abAB. I actually think it works better than “regular” villanelles.
How about the julainnet? xaa xbb xcc xdd ee, or perhaps abb acc dee dff gg?
I think that has real possibilities.
