Tanka is a Japanese poetry style similar to haiku, but a bit longer. Its syllabic formula is 5-7-5-7-7, and like haiku, tends toward themes of nature and the seasons. I find it to be exactly the wrong length, and therefore irresistible. Here’s one.
I dream of islands
Tomb-spattered and draped with vines
The sweltering summer stench
Along paths of memory
