Triad Dissonance 3D
Explore a triadic relief where pitch ratios become a surface of consonance, roughness, and harmonic tension.
Triad Dissonance 3D projects a triad space onto a surface where two axes carry frequency ratios and the surface height expresses perceived roughness.
The page lets you switch music systems, constrain the note pool to a scale, adjust base frequency, grid density, and partial count, then recompute an entire harmonic landscape.
The goal is not only to show an attractive form, but to connect intonation, quantization, sensory roughness, local consonance, and listening to selected triads inside one exploratory instrument.
This experience works as a lab for comparing stable, unstable, or ambiguous zones across chords, scales, and tuning worlds.

About this graph
This visualization fixes one tone and varies two other tones by ratio. Each point on the surface represents one 3-tone sonority.
Lower regions generally correspond to more consonant combinations, while higher regions correspond to more dissonant or rough combinations.
The graph can be quantized to your music systems and scales, so clicking the surface can explore consonance within different tuning worlds.
