Comfortable counting syllables and rhyming? Try the Clogyrnach. This is an old Welch form of poetry. Some of these poetic forms were more fun than others. I found this one a fun start to conforming to rules.
Here are the rules:
Line 1: 8 syllables ending with an a rhyme
Line 2: 8 syllables ending with a b rhyme
Line 3: 5 syllables ending with a b rhyme
Line 4: 5 syllables ending with a b rhyme
Line 5: 3 syllables ending with a b rhyme
Line 6: 3 syllables ending with an a rhyme

A pause, all is lost in aw.
An empty lap.
No gap in ardor
