# 5-7-5 I realised 5-7-5 ~ U - U = Amphibrach 7-5 ~ - U = Trochee 7-7 ~ - - = Spondee in a larger scale. So maybe things like [x-7-5-7]-[x-7-5-7]-[x-7-5-7] would make sense. A 12 = 3*4 lines poem. Mimicking the iambic trimeter. Or [5-7]-[5-7]-[5-7]-[5-7]-[5-7] like the iambic pentameter. Though 5-7-5 itself is so comfy.
