Yes, that's the way I interpret the diagram. I think the importance of there being five tonal regions is that this enables the multiples of 12 to line up at 60. These numbers are significant because they connect back to the Babylonian sexagesimal ("base 60") system used in both music theory and trigonometry. https://en.wikipedia.org/wiki/Babylonian_numerals |
