A concrete poem can have any number of lines; its structure is highly flexible and determined by the poet’s intention. Unlike traditional poems that follow strict formats, concrete poetry focuses more on the visual arrangement of text on the page. The ‘lines’ of a concrete poem may not even be linear in the traditional sense—they can be shaped to form images or patterns that relate to the poem’s theme or subject.
This means that some concrete poems may consist of just one line or even a single word, while others could span several lines or create complex shapes. The creativity lies in the poet’s ability to merge the language with visual art, leading to a unique expression that transcends conventional poetry.
