- 20 lines
- iambic (pentameter/quatrimeter/trimeter) in a regular, repeating pattern (like 5 quatrains, or 4 quintrains)
- rhyme scheme also in a regular repeating pattern (but not the same one as the rhythm scheme)

Thus, the cycles of rhyme and rhythm overlap and syncopate, because they are of different lengths.

Example:

~/~/~/~/~A
~/~/~/~/~B
~/~/~/~/~B
~/~/~/~/~A
~/~/~C
~/~/~/~/~D
~/~/~/~/~D
~/~/~/~/~C
~/~/~/~/~E
~/~/~F
~/~/~/~/~F
~/~/~/~/~E
~/~/~/~/~A
~/~/~/~/~B
~/~/~B
~/~/~/~/~A
~/~/~/~/~C
~/~/~/~/~D
~/~/~/~/~D
~/~/~C

In this example, the rhyme-scheme is a simple repeating ABBA scheme (that is, a four-line pattern), but the rhyme of the iambic pentameter is broken up every 5 lines by a trimeter line.
