How do you write it? An Ottava Rima is a poem composed of eight lines that have an ababababcc rhyme scheme for the first stanza, and dededeff for the next, the rhyme scheme keeps going down the alphabet until you can no longer rhyme. Each line should contain either 10 or 11 syllables. You can make a single octive (eight line stanza) or multiple, it's up to you. In these eight lines attempt to make a coherent story, it can be fiction or non-fiction. If you do not understand how to create it from my description try checking out the rules on this website: http://www.shadowpoetry.com/resources/wip/ottavarima.html I will post an example for reference.
