Loop poetry, is a poetry form created by Hellon. There are no restrictions on the number of stanzas or the syllables. The last word of the line one becomes the first word of line two, last word of line two becomes the first word of line three and so on. A rhyme scheme is followed that is abab.
There are variations as well.
A stanza can be long with the last word – first word scheme maintained. Rhyme scheme need not be followed.
Couplets of 4 lines each, can be used where the last word – first word scheme is maintained in each stanza.
Check out the poem The Conversation under Poetry. It is written in the loop format.
