Dissoinen

Dissoinen is a term that has appeared in niche music theory discussions to describe a supposed class of dissonant sonic phenomena. The term is not part of standard music theory and has no widely accepted, formal definition. When used, it generally refers to patterns in which two or more sonic streams produce rapid or structured dissonant interactions, sometimes across a single line or group of voices that challenge traditional harmonic expectations. Some writers frame dissoinen as a label for temporal dissonance created by alternating tonal centers, while others use it to describe a texture in which dissonant intervals are alternated with consonant ones to generate a sense of instability.

Etymology and scope: the word appears as a neologism built from a dissonance-based root with a generic suffix, and there is no single agreed-upon etymology. Usage is varied by author and context, and there is no standardized formalism accompanying the term. In practice, discussions of dissoinen tend to emphasize perceptual outcomes rather than codified rules, making it more a descriptive metaphor than a formal theory.

Usage and reception: because the term is not standardized, its application differs among composers and theorists. It is sometimes discussed alongside related concepts such as dissonance, polytonality, and sequential harmony. Critics argue that the term can add little clarity without a precise definition, while supporters see it as a useful shorthand for certain dissonant textures and listening experiences.
