Ergodic Quatrain refers to a four-line stanza that demands nontrivial effort from the reader to traverse its textual path—whether through visual layout, syntactic complexity, or interactive elements—drawing on the concept of ergodic literature (from Espen Aarseth) where the act of reading becomes a form of labor or navigation; such quatrains might employ palindromic lines, embedded puzzles, or typographical disruption, challenging passive consumption and inviting the reader to co-create meaning through active engagement, as seen in concrete or digital poetry experiments.

Four-line stanza requiring reader participation or multiple reading paths. Ergodic at stanza level. Rare form. Related: ergodic poetry, interactive verse. Study: how choice operates.
