harmonicisiin

Harmonicisiin is a term used in music theory to denote a proposed class of harmonic relationships and transformations that organize chords and tonal centers according to a defined set of rules. In theoretical discussions, harmonicisiin structures emphasize coherent voice-leading, controlled modulation, and the emergence of stable tonal centers across extended progressions. The concept is employed in analytical work and in algorithmic composition to model how harmony can evolve while maintaining perceptual coherence.

The term appears to be a neologism blending the notion of harmony with linguistic forms that suggest collectivity or categorization. Its exact etymology is not standardized, and usage varies across scholarly communities. As a concept, harmonicisiin is not tied to a single historical school but rather to modern discussions of how long-range harmonic relationships can be formalized and analyzed.

Core characteristics commonly associated with harmonicisiin include: a defined set of permissible chord transformations between tonal regions; a constraint on voice-leading that favors smooth movement and avoids undesirable parallels; and a hierarchical organization of chords into families that guide progressions toward recurring or emergent tonal centers. Proponents argue that these features support predictive models for harmonic motion, particularly in pieces with extended forms or post-tonal textures.

Applications of harmonicisiin appear in computational music systems that generate plausible harmonic progressions, as well as in theoretical analyses of complex works. Critics note that the concept remains abstract, with multiple competing formulations and varying practical usefulness depending on context.
