Want to try triolets? (ABaAabAB)

tri.o.let: a poem or stanza of eight lines in which the first line is repeated at the fourth and seventh and the second line as the eight with a rhyme scheme of ABaAabAB.

The trick to writing a good triolet is to arrange that the repeated lines take on slightly different roles, semantically or even syntactically, in their various positions.

How To Triolet

Example:

Butchered
by John Thele

Virtual memory is like a knife sharpened carefully;
The programmer like the sculptor in search of perfection.
Each whittles ardently, for a stray cut spells catastrophe.

Virtual memory is like a knife sharpened carefully;
The operating system like the butcher serving many.
Each chops quickly, their concern not for optimization.

Virtual memory is like a knife sharpened carefully;
The programmer like the sculptor, in search of perfection.
