Acrotomophilia

In his book, Debridement, Corrina Bainn focuses a great deal on what's missing. Not just thematically but also in his forms. There are a series of self-erasure sonnets and villanelles where the author has written in form and then taken parts of it out, leaving what looks like free verse poetry.

April Penn uses the technique here.

Sonnet Self-Erasure
(after Corrina Bain)
April Penn

I felt the dead girl
                                         over my face
a veil        
                                         destroying me softly.
So not profound to die
              spoke
              my worst                        soul    
                                to rock
                                                        another world
              inside of me
                               how poetry must quarrel
              with        
                               the rehearsal of
                                             fall.
