The GnosticAcademy YT channel recently pointed out some ancient knowledge that was new to me: when you divide the 22 bones of the human skull (not counting the mandible) by the 7 orifices of sensory input in the head, you approximate Pi, the result being 3.142.

When I heard this, I wanted to know how these numbers fit within the harmonic series, which is where my mind always goes.

So, in the harmonic series, harmonic 22 is the note of F# (it enters the series at harmonic 11).

And harmonic 7 is the note of Bb, entering the series at right at 7. (New notes always enter the series as odd numbers. Even numbers are simply octave repeats.)

In the harmonic chromatic scale, these notes have scaled up to 22 and 28 (below). Both are matter-based, power-of-2 numbers that reduce to 4 and 1, respectively. (The numbers 1-2-4-8-7-5 are all based on the power of 2, while 3-6-9 are based on the power of 3.) This suggests that the human head’s ability to perceive the physical world is a matter-based function. No surprise there.

Within the harmonic chromatic scale between harmonics 16 and 32, F# shows up 6 notes in, and it takes another 6 notes to reach Bb.

The number 6 is such a strange, overlapping number, because although it’s clearly based on the power of 3 (3-6-9), it’s a doubled (2) octave of 3, so it seems to straddle the powers of 2 and 3. It also produces a locked oscillation with the number 3 as they scale up through their octaves.

But dividing the harmonic chromatic scale into 6, 6, and 4 is a clue to something hidden: we’ve been told the musical chromatic scale only contains 12 notes, but after 12, we’ve only reached Bb at harmonic 28. How do we conclude the scale at harmonic 32?

In the harmonic chromatic scale, there are 4 notes left over because this scale contains 16 notes, 4 of which are place holders, allowing us to tune the scale more justly than man-made temperaments can achieve. This hint was also subtly revealed in the novel, ** The Phantom of the Opera**. Notice, again, we’re looking at the numbers of 6 and 4:
