As a matrix for comprehending the relationship between the Golden Ratio & the Octave, as well as a mnemonic for mapping the circle of Fifths (descending clockwise) & circle of Fourths (ascending counter-clockwise) onto the chromatic Scale, the 8th Octahedron (=231) is subdivided between its' 8th & 11th courses (Notes G & A, respectively) when unison is set at Note D. This conforms to the Pythagorean tuning of the chromatic scale that produces the Ionian mode. By placing the Perfect Fifth (3:2) at Note A (Key pitch) and the Perfect Fourth (4:3) at Note G, One subdivides the 13 courses of the 8th Octahedron in accord with the Fibonacci sequence both structurally and astronomically.
To illustrate:
Summing from the first course (or ‘layer’) of the 8th Octahedron, the Perfect Forth (4:3) is set after the 8th course [176 = ∑ (courses 1-8)], while the Perfect Fifth (3:2) is set before the 11th [226 = ∑ (courses 1-11)].

This Pythagorean Tuning of the Chromatic Scale is seen as a progression of 11 cycles of Perfect Fifths.
However, 11 perfect Fifths doesn’t fit 7 octaves exactly.
