Hi Vicky. I saw this at the link Karen gave..shadowpoetry.com. I copied and pasted this part about the Triolet.......
A Triolet is a poetic form consisting of only 8 lines. Within a Triolet, the 1st, 4th, and 7th lines
repeat, and the 2nd and 8th lines do as well. The rhyme scheme is simple: ABaAabAB, capital
letters representing the repeated lines.
Make writing a Triolet more challenging! Make each line 8 syllables in length (4 metrical feet),
written in iambic tetrameter (the more common way), or try it in pentameter (English version)
where each line only has 10 syllables(5 metrical feet).
In the examples, though, most of them capitalized all of the first letters of each line. So, I guess it doesn't really matter, right?
