Etymology: "Dysodyne" is a rare technical term built from Greek. Its first part, "dys-", means "bad, ill, hard" (as in "dysfunction" or "dyspepsia"), and the second part comes from "ōdýnē", the Greek word for "pain" or "grief," with "-ine" giving an adjectival sense. Taken together, the word is a coinage meaning something like "painful-sounding," describing a dissonance harsh enough to feel like an ache to the ear. No dictionary I can confirm records it in use before the modern era, so it is best understood as a deliberate musical coinage rather than a term that passed through centuries of speech. Writers who need a precise word for the unpleasant effect of certain intervals have often reached for Greek roots like this one, because they sound scholarly and carry clear sense for readers who know those components.
