The concessional structure is a two-part structure that turns from making concessions (that is, admitting the problems or difficulties in the argument one wants to make) to then, in fact, making the argument. Mary Szybist discusses the concessional structure more fully in Structure & Surprise: Engaging Poetic Turns. Below are supplemental poems and discussion.
Generally, the concessions in the following poems are the repeated claims that it seems so much of what is good is gone, or about to go away. Creating and employing this sense of being at the end of things, these poets then represent–sometimes encouraging, sometimes just relaying–a new encounter with what is or might be present, or possible. The motto for this kind of concessional poem might be the first two and the final line of Wallace Stevens’s “The Well Dressed Man with a Beard”: “After the final no there comes a yes / And on that yes the future world depends….It can never be satisfied, the mind, never.”

“Building, Dwelling,” by Michael Theune (in American Poet: The Journal of the Academy of American Poets 32 (2007): 14). This ending is also a bit ironic.
