The Yadu is a Burmese form of poetry that uses climbing-rhyme. This stanzaic form is dedicated to the seasons (the word yadu itself means ‘seasons’) and express the emotions the seasons evoke. It can have a maximum of 3 cinquains (5-line stanzas). The first four lines of a stanza have four syllables each, but the fifth line can have 5, 7, 9, or 11 syllables. The rhyme is required on the fourth, third, and second syllables of both the first three lines and the last three lines. The end of the last two lines also rhyme.
Here’s how a Ya-du is structured :-
-b–c (for a 5 syllable line variant)
To sum up how the climbing rhyme works, look at the structure once. See how the 4th syllable of Line 1 rhymes with the 3rd syllable of Line 2 and the 2nd syllable of Line 3. The 4th syllable of the Line 3 rhymes with the 3rd syllable of the Line 4 and the 2nd syllable of the Line 5. Line 4 and Line 5 end rhyme.
Here’s something I wrote as a Ya-du :-
The yellow moon
under noon clouds
Mid-June at play
ripe grey, summer’s might
