A seam may join two speakers, time periods, genres, registers, or modes of attention. It can be signaled by a stanza break, a change in syntax, a typographic shift, or a repeated phrase that changes meaning at the crossing. Concealing every seam can make a poem feel falsely uniform, while emphasizing one can reveal its construction and ethical tensions. In collage and documentary poetry, seams help readers distinguish sources and witness the negotiations required to make disparate materials share a page.

A seam is the perceptible join between unlike materials, such as lyric and narrative, formal diction and slang, quotation and invention, or one speaker’s voice and another’s. A visible seam can expose construction and create energy, while a concealed seam can produce smooth continuity. Poets should decide whether the transition needs a hinge, repeated image, change in rhythm, or deliberate abruptness. Related concepts include montage, juxtaposition, and transition.
