The only things truly universal in music are those that are based on biological and/or perceptual facts. Tuning Timbre Spectrum Scale focuses on perceptions of consonance and dissonance, which are defined in the Harvard Dictionary of Music: ?Consonance is used to describe the agreeable effect produced by certain intervals as against the disagreeable effect produced others. Consonance and dissonance are the very foundation of harmonic music… consonance represents the element of smoothness and repose, while dissonance represents the no less important elements of roughness and irregularity.?
