The Ya Hoo is an enhanced version of the Yadu.
It was invented by Lawrencelot of AP
There are 1 to 3 stanzas, each with five lines.
Each of the first four lines have four syllables.
The last line has either 5, 7, 9 or 11 syllables.
The defining feature of this form is that it has internal staircase rhyme, as does the yadu, but unlike the yadu it has right and left staircases.
Also unlike the yadu, there is NO requirement that the poem have a theme about seasons.
Here is a syllable schematic of the rhyme required.
Maybe Time, by Lawrencealot
Shine a dim light
of fine nightowl
sky; white wine pour
for my poorgal.
She’s sore. Why? I dunno but I see a scowl.
I could propose
then I ‘spose she
would close my night
out good, right?We
don’t fight. Should work for everybody.
