10 = 1 + 2 + 3 + 4

   .       odd  peras   point
  . .      even apeiron line
 . . .     odd  peras   plane
. . . .    even apeiron space



1:2 = (Octave) = (Diatonic)
1:3 = (Tritave) = (Bohlen-Pierce)
1:4 = (Double Octave) = (Octave)^2
2:3 = (Perfect Fifth) = (EDFs)
3:4 = (Perfect Fourth) = (Perfect Fifth)^-1

Thus Diatonic, Bohlen-Pierce, EDFs are the backbones.
Octave, Tritave, Perfect Fifth.
2, 3, 2:3.



If you limit, 6 = 1 + 2 + 3 = 1 * 2 * 3
The factors of 12: 1, 2, 3, 4, 6, 12

3 = 1 + 2
Semiosis is the Unity of Being and Becoming.
