Consonance is the state of harmonious combination where simultaneous sounds or elements blend without acoustic or perceptual clash. It exists as a qualitative judgment made by listeners — trained or untrained — that certain combinations of frequencies produce a stable, unified percept rather than friction or beating. Parameters: (1) acoustic: intervals with simple frequency ratios (octave 2:1, fifth 3:2, fourth 4:3) are most consonant; (2) contextual: consonance varies across musical cultures and historical periods; (3) perceptual: it is experienced as stability and rest, the counterpart to dissonance's instability. Persistence: the concept persists through music-theoretic teaching, acoustic analysis frameworks, and cross-cultural aesthetic categorization.

Definition
Why it is in scope
A human-made conceptual category from music theory and aesthetics: the state of harmonious combination where simultaneous sounds or elements blend without clashing. Consonance is the qualitative judgment that two or more tones produce a stable, pleasant fusion — it exists as a perceptual construct evaluated by trained listeners, not as a physical property of the sounds themselves.

Consonance (harmonious combination of sounds) is maintained for the sake of music — it creates the pleasant auditory experience that music aims to produce. The designed purpose of consonance in musical practice is to serve musical aesthetics. Law 8d: servant (consonance) points at master (music).

Consonance IS a specific kind of harmony — the partial or full acoustic harmony where simultaneous sounds blend without perceptual clash. A competent speaker would call consonance 'a kind of harmony' (specifically acoustic harmony). Law 9: specific→general.

Consonance is a perceptual phenomenon — the experience of sounds blending without clash. Remove sound and consonance ceases to operate entirely. This is object-level (not meta-level Law 2b): consonance IS a property of sound, not a concept that merely needs language to be said.

Consonance as a musical concept IS the quality of frequency ratios that appear in the harmonic series (2:1, 3:2, 4:3). Remove the harmonic-series concept and consonance loses its defining criterion — it becomes a subjective feeling rather than a defined acoustic relationship. The removal test passes: without harmonic-series, consonance as a concept cannot operate.
- cmsonzqyp02b2jlss505mrhmiDEPENDS_ON →
Consonance is defined as the quality of harmonic compatibility between pitches, determined by the relationship of their overtone series. Remove the concept of overtone and consonance cannot operate — there would be no framework for describing how pitch relationships are perceived as stable or unstable. This is a constitutive dependency, not mere association.
