Hello Beautiful Thinkers,
The Cascade poem uses each line from the first stanza of a poem as the final line of each stanza afterward. So if your first stanza was a tercet it would look something like ABC, abA, cdB, efC. (Each letter being a new line and each comma marking the end of a stanza. The lower case letters can be pretty much anything there are no rules about rhyme scheme.) So as you can see it can be as long as you want it to be. Most of the examples use a standard of tercets for the stanzas. But I don’t see why we can’t take creative license with that as long as we keep the original rule of reusing the first stanza as end lines. While it does give the poem a nice aesthetic I don’t see why all the stanzas even need to have the same line count if you don’t want them too. Get creative with the form and do what feels right for you.
