Hugo Riemann
Riemann and dualism:
Major and minor chords are inversionally related forms of the consonant triad
Riemann believed in the existence of an undertone series up to 1905 "Das Problem des harmonischen Dualismus"
For the major triad, the proportion relates to frequency and, for the minor, wavelength
