Major Chord Triad Ratios as Bands of Air Pressure - Separated

Summary

[edit]
Description
English: This is all somewhat speculative and unproven, heuristic perhaps, but I have not found any reasonable alternative explanation which is visually convincing.

The three notes of the Major Triad, each with their first 6 Partials in Fourier derived relative strengths are shown as bands of increased air pressure. Separated from each other to demonstrate the repetition ratios of 4:5:6, a Minor Third Interval over a Major Third Interval with a Perfect Fifth Interval of 6:4 reducing to 3:2 between the highest and lowest notes.

The ratios are more determinative than the exact alignment.
