Poco te puedo ayudar, pues soy de ciencias, pero te copio las primeras estrofas de Las Aventuras de Tom Bombadil. La primera estrofa es de seis versos (AABBCC), pero las demás, hasta el final, son de cuatro, rimando AABB. En inglés, claro, que es como riman. En élfico tienes varias en ESDLA, que puedes copiar y comprobar.
Suerte.

Old Tom Bombadil was a merry fellow;
bright blue his jacket was and his boots were yellow,
green were his girdle and his breeches all of leather;
he wore in his tall hat a swan-wing feather.
He lived up under Hill, were the Withywindle
ran from a grassy well down into the dingle.

Old Tom in summertime walked about the meadows
gathering the buttercups, running after shadows,
tickling the bumblebees that buzzed among the flowers,
sitting by the waterside for hours upon hours.

There his beard dangled long down into the water:
up came Goldberry, the River-woman's daughter;
pulled Tom's hanging hair. In he went a-wallowing
under the water-lilies, bubbling and a-swallowing.
