Helmholtz’s timbre rules map onto the axes of modern timbre-space experiments

Evidence

His second and fourth general rules make a clear distinction between sounds in which partials higher than the sixth or seventh are distinct or not, and his first rule gives a particular importance to the f0 component. It is worth noting the similarity with the axes of the tristimulus diagram as well as axis (I) resulting from Grey’s multidimensional experiment. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1497
