Over time I've collected a few references to quantitative verse forms from different poetic traditions. The primary feature of these systems is that syllable weight is the defining measure of verse, rather than patterns of stress or syllable counting.
- Greek Verse
- Vedic Metre in its Historical Development
- Poetries in Contact: Arabic, Persian, and Urdu (this is great!)
- Somali Prosodic Systems
- Metrical structure and sung rhythm of the Hausa Rajaz
- Introduction to Tamil Prosody
I'm sure there are some traditions I'm missing.
I've never successfully created a poetic system for one of my conlangs. Though Kílta has vowel length, it looks like syllable counting will be the way to go for it, but there are still plenty of experiments to work out.
