darythmie

Darythmie is a term that appears infrequently in contemporary usage and does not have a single consensus definition. In English-language sources it is often encountered as either a misspelling or a neologism related to irregular rhythm. Because of its scarce attestation, the term is typically described in passing rather than established as a formal concept.

In musical and artistic contexts, some writers use darythmie to denote irregular or nonisochronous rhythm, including irregular meters, cross-rhythms, or asymmetrical accents that disrupt a steady pulse. In these uses, it functions as a descriptive label rather than a formal theory, and its exact scope varies by author.

In medical usage, the standard term is dysrhythmia (or aryhythmia in some languages). Darythmie is not recognized as a medical diagnosis and should be distinguished from arrhythmia or dysrhythmia for clinical purposes.

In other domains, including linguistics or poetry, darythmie may appear as a playful or experimental descriptor for irregular timing of syllables or stresses, though this usage is similarly informal.

Etymology and origin remain unclear, with possible influences from French arythmie/arythmie or English dysrhythmia, but no authoritative derivation is established.
