Whole tone and leading notes derive from intervals above the dominant in just intonation

Evidence

The frequency ratios of B and D are a major third (5:4) and a perfect fifth (3:2), respectively, above the dominant, G, and they are related to C as: 5 4 5 4 3 2 15 8 3 2 1 2 3 2 3 2 1 2 9 8 (The result for the D is brought down one octave to keep it within an octave of the C.) — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1026
