Chord Spacetime

Human spatiotemporal experience comprises two fundamental solution structures: chord-tonal spacetime and non-chord-atonal spacetime. Chord-tonal spacetime uses the chord spectrum as its encoding structure, generating spatiotemporal experience through spectrum-semantic mapping. Typical forms include tonal music (temporal domain) and color painting (spatial domain). In this model, spacetime manifests as a coherent chord field, tending towards triad resolution, exhibiting discretized characteristics (n · f, f/n, mod12). Non-chord-atonal spacetime shields the chord spectrum, primarily describing geometric and kinematic relationships, achieving quantification through clocks, scales, and reference frames. Typical forms include classical physical phenomena, sketching art, and noise music. In this model, spacetime manifests as a geometric-coordinate framework, tending towards achromatic-noise resolution, exhibiting continuous characteristics (x, y, z, t).
