The pattern of word-repetition is as follows, where the words that end
the lines of the first tercet are represented by the numbers “1 2 3”:
  1 2 3          – End words of lines in first tercet.
  3 1 2          – End words of lines in second tercet.
  2 3 1          – End words of lines in third tercet.
  (1 2 3)        – Words contained in the final line.
Your Composition.
The repetition of words in a Tritina makes this form a good match for
a story that uses common speech, for in conversation the repetition
of key words is common. The Tritina is a more “natural” form than the
Villanelle (which is comparatively artificial in repeating whole lines)
and the Sestina (which is significantly more challenging because it is
longer (39 lines) and reuses six words
in six six-line stanzas and a closing tercet).
Example Poem
I have  always liked dogs.
Almost all dogs I like.
And almost all like me.
Their faithfulness moves me.
I prefer smaller dogs
‘Cus big poop, I  don’t like.
Of course I  still do like
gals who are nice to me.
as long as they like dogs.
I like dogs;  dogs like me.

S.E.Asia. (Burma)
Ya Du
The yadu is a Burmese climbing-rhyme verse. Each of the stanzas —up to three in all— has 5 lines. The first four lines have 4 syllables each, and the last one can have 5, 7, 9, or 11 syllables. The last two lines rhyme in the usual way. The climbing rhymes occur in syllables four, three, and two of both the first three lines and the last three lines of a stanza. There should be a reference to the seasons since the word yadu means “the seasons.
As the Than Bauk is to the Haiku, then the Ya Du is to the Tanka
and consists of four syllable lines and a fifth one that can
comprise of 5, 7, 9,or 11 syllables.
The staircase rule applies to the four lines,
and the last syllable of the fourth and fifth
line must rhyme, giving a pattern of:
O. O. O. a.
O. O. a. O
O. a. O. b
O. O. b. c.
O. O. O. O. O. O. O. O. c.

Example Poem
Blue sky’s curved moon
appeared at noon, as
gray loon’s song note
surged afloat clouds —
bird’s songs circled dreams, quietly abound.
We watched it stay
on its way, silk
breaths swayed tree leaves;
freshly weaved thoughts
seized summer notions the afternoon moon brought.
