Erasure poems are a form of found poetry in which the poem is produced by erasing unwanted words from the page. The words that are not erased or covered form a new poem. Thus, it can be seen as a variation of or complement to blackout poetry.
Blackout poems, also called redacted poems, are a form of found poetry in which the poet produces a poem by literally blacking out the words from a preexisting article or text. This process is usually done with a marker, black highlighter, etc. The words that are not covered constitute the poem itself.
Dada poetry is not one strict term, but rather any poetry produced as part of or in mimicry of the Dada movement (aka Dadaism). These poems are usually made utilizing random chance, such as pulling words out of a sack, tossing a random assortment of newspaper clippings onto a table, etc.
Cut-up poems also called ‘remix poems’ or ‘découpé’ poems, are an offshoot of found poetry in which a poem is generated by cutting apart a preexisting work and rearranging pieces of it into a new poem. The physical act of cutting is arguably a core feature of the form, though the digital era may expand the definition.
Chance operations are poem generation techniques that basically leave the compositional operation to “chance”, such as the rolling of a dice, or tossing of a coin. Poems that are created by using chance operations typically source texts from famous written literary works, magazines, and even newspaper articles.
