I started to analyze [the poems] so I could do more (I never left myself any notes on how I made it). It's a pretty interesting idea, actually, and fairly complex. This is its rhyming pattern: ABAB CDCD EFEF AA. (I also wrote one that was ABAB CDCD EFEF GG.) There are severak ways to do it, but there's one way that I think is best: it's basically an extended limerick, the stanzas corresponding to certain areas on a limerick. The first stanza corresponds to the first two lines of a limerick, the A lines being the first two lines of a usual limerick, while the B lines are an expansion of the story told by the limerick. Using an example (the first one I made):
A There once was a man from the stars,
B Not quite Sirius, a bit to the left;
A Who liked to play tag with his scars,
B For that was his burden to heft.
C They'd slide and they'd scoot,
D And dance, scream, and play,
C And they'd run all aboot,
D Every night and all day...
E And though he was pained,
F And quite ill at ease,
E Whenever it rained,
F He climbed in the trees.
A Sometimes toy soldiers fight in make-believe wars,
A For no one can rightly shut all the mind's doors.
(This is NOT my best limnet.)
The Original Limerick that one was based on:
There once was a man from the stars,
Who liked to play tag with his scars.
They'd slide and they'd scoot,
And they'd run all aboot,
Toy soldiers in make-believe wars.
So the first stanza corresponds to the first two lines of a limerick, with expansion. The second stanza therefore corresponds to the BB lines of a limerick. So does the EFEF stanza: that stanza can be either a mere expansion or it can correspond to an alternate pair of BB limerick lines. This way it's like having two limericks in one.
And, of course, the final two lines correspond to the final line of a limerick. I have found, interestingly enough, that GG can work as well as AA for this.
