PassingNot

Passingnot is a term with no widely established definition in published literature. It appears mainly in informal online discussion and in niche writings, where its meaning is highly context dependent. In many cases, it emerges as a typographical variant of a more common term such as “passing note” or as a coined label within a specific project or community.

In music theory, the standard concept related to a similar word is the passing tone or passing note—a non-chord tone that connects two chord tones. Some writers who encounter the form “passingnot” do so by mistake or as a stylized spelling, and the one-word form is not recognized as a separate technical term in mainstream pedagogy. In programming and software development contexts, “PassingNot” or “passingnot” has occasionally appeared as a function, class name, or namespace in individual codebases; such usage is idiosyncratic and not indicative of a general principle.

In philosophy, logic, or linguistics discussions, a few commentators have used variants of the term to discuss negation or the status of negation in argumentation, but these usages are informal and lack standard definitions. Because of its uncertain provenance, readers are advised to interpret passingnot strictly from the context in which it is found and to consult accompanying explanations or source material for clarification.
