Let's try a nonet for this prompt.

A nonet has nine lines. The first line has nine syllables, the second line eight syllables, the third line seven syllables, etc... until line nine that finishes with one syllable. It can be on any subject and rhyming is optional.

line 1 - 9 syllables
line 2 - 8 syllables
line 3 - 7 syllables
line 4 - 6 syllables
line 5 - 5 syllables
line 6 - 4 syllables
line 7 - 3 syllables
line 8 - 2 syllables
line 9 - 1 syllable
