Analog propagation is what I know.
Well, me too. We exist in the linear dimension of transects and that is all we know. Anything that goes beyond that linearity is considered "Mysticism" (or possibly Quantum Mechanics").

the ability for this to occur at once everywhere across such a vast span is staggering.
That "vast span" is merely your perception. In Spectrumology there is no "spatial span", the Universe to the Spectrum is just what it's called, a unit. This is not an "ability" of the Spectrum, because by its nature it is vibrating everywhere at once, so it is generating the "space" we perceive continually. Apparently it is a result of the harmonic 6, or rather the interaction of 2 & 3.

Please if you can describe in simpler terms what drives this from origination to end so quickly that it is "on" then "off" everywhere at once.
I guess what I mean is that there is space, and that there is more dense space which is matter. Matter is a certain structure of harmonics that we perceive as solid when really it is "packed harmonics". So I propose that matter and all particles is actually compressed space.
The "propagation" of harmonics may be analogous to electromagnetism. At the beginning of the disovery of electromagnetism it was simply unthinkable that this force could be so fast and unencumbered by space/matter. It is simply a limitation of our mind.

People see patterns where no patterns exist. In its extreme cases it's destructive paranoia. A person who never sees patterns is dull. If it's there, but not overwhelming --not an illness-- and the person is a scientist or artist, it can be useful in suggesting avenues for investigation and progress and fun. I'm not sure where on the scale you are, Gnarlodious. I like your website because I can't tell whether you really believe in the system you present or you're cleverly parodying numerology and the new-age pseudosciences for an art piece. I hope it's the latter, but that doesn't really matter. It's attractive.

Excerpts of conversations with John Englemann, whose music page is Pont du Avant-Garde.
If you scroll down the page you find a composition titled "Tinnitus Transformations", an accurate acoustic rendition of the medical condition tinnitus, which is an unexplained ringing of the ears.

The noise, what bothered me was that it was so eternal. . .
It is eternal. It extends from the beginning of time to the end of time.
Sometimes I wake up in the morning and I feel myself awash in a sea of vibration, it is almost liquid in viscosity.
The Spectrum is an ocean of harmonics, the matrix of our birth. It is everywhere at once. It saturates all levels of matter. The Universe resonates with it.

Like, where does one get all these ideas?
It is my experience and perception of the universe. A gift of mutation. Fact is indeed stranger than fiction! I could never have invented all this stuff!
Part of the problem I am having with people commenting on my work is that they perceive it as a "conjury" or a "delusional system". They may be comparing it with other "alternative explanations" and grouping it in that category. I have wondered at the wisdom of mentioning the ideas of Terence McKenna or Art Bell, does that damage my credibility? I don't know. How can you force someone to take your life's work seriously?

At one time I performed an experiment in which I held a microphone to my ear with an amplifier cranked all the way up, and I believe I heard my tinnitus (softly, but surely) over the speaker. I don't know why I didn't pursue further possibilities of that at the time.
My explanation of this phenomenon is Resonance.
While I admit that the actual audio waves may be transmitted from the ear tube, it seems more likely that the molecule that is responsible for hearing is responding to the proximity of another resonance which boosts its output above the threshold of hearing. This means that if you got enough resonant people together in a small place even the non-afflicted would hear the noise. So called psychics, mediums and preachers are doing this all the time, it is a well documented collective experience though no one has ever explained the mechanism.

I have often wanted to build an acoustic simulator that will generate the tinnitus sequence in audio waves. But alas, that would take money.

It has occurred to me that the sound resembles rapid morse code, or perhaps the sound of a TTY
Funny you mention that. As a therapeutic activity I listened to morse code for years, it is like a second language to me (K5ZN) . At that time though, it seemed to give me an auditory reference point thus reinforcing my belief that I was sane.
After my initial assumption that I was mentally ill and hallucinating, I began to accept the noise and later to consider it a gift of creation.
I am also a huge fan of middle eastern music, the tones typical of Arab and Israeli music are very similar to the tinnitus.

Assuming you have vision, perhaps you have noticed "sparkles" or "static" or "snow" throughout your visual field underlying everything you look at, especially when observing a uniform monochromatic area such as the sky.
I believe this lies within the category of synesthesia. Part of my somatic sensations are rapid flashes of light which happen at transits of harmonic 47 but there may be another explanation.
Astronauts in orbit report that while resting in total darkness they see flashes and sparkles of light when the never saw this on the land. This is theorized to be the result of high energy cosmic rays decaying in their visual mechanism. This does not normally happen on the land since we are all shielded by hundreds of miles of air molecules.

By "molecule that is responsible for hearing", do you mean the molecule that triggers the sensory hairs in the cochlea/auditory nerves?
Yes, I think that is what I mean, even though I do not know what specifically the biology of hearing is, my outlandish theories are based on "what makes sense" after years of thinking about it.
In this case, I theorize a dry chamber that contains one DNA molecule that hangs from one end. Probably in most people it is connected at both ends, these will be the people who do not "resonate" due to the fact that the free end of the strand is dampened when anchored.

I occasionally have sensations of an incomprehensibly vast plane, and my head is exponentially increasing in size. I never really thought about what causes these perceptions.
Yes, I have examined the harmonics during these hallucinations with no obvious results, so I assume it is simply "mental idling".
My similar perceptions are experiencing the universe as having the approximate structure of a "plate of spaghetti", or moving being compressed through a long dark tunnel and others too weird to describe.

I don't believe I have a documentable case of synaesthesia; however, I have associated numbers, letters, musical tones, historical periods, and so forth with specific colors for as long as I can remember.
One of my ambitions is to create a compendium of musical chords, colors, language and visual patterns which are all associated with the respective harmonics. My "Cognition" page is the start of this. I suspect there are even "cartesian mathematics" associated with chords. You are obviously very attuned to this intuitive awareness as are many musicians and poets.

These less random forms have the appearance of modern paintings--brightly colorful, with shapes sometimes squiggly and sometimes angular.
Jackson Pollack maybe?
But seriously, that is like this kind of hallucination I have when I am resting and hear a sudden noise. A "snapshot" happens in my eyes of all sorts of kaleidescopic patterns depending on the kind of noise.
I have wondered what this reveals about my mental processes.
Did it ever occur to you that we are actually borderline psychotic? These perceptions are what psychotics experience as reality all the time. We are rational and that tempers the hysteria those perceptions would otherwise cause. Can you imagine being overpowered by raw hallucinations constantly and reacting to them?

Credibility is in repeatability. Thus is science. Harmonics, what can it predict based on previous trials?
For starters, see "proof".
I could predict what a statistically large enough sample will dream about at a given time.
I could predict what unmedicated psychotics will verbalize at a given time.(The same mechanism is causing both phenomena)
I can also and eventually will prove that previous civilizations knew about this science and their language was engineered according to it. This is the point of all the Chinese characters.
I believe I can also (eventually) show that the group of people who suffer severe tinnitus will agree that what they are in fact hearing is no less than the harmonic vibration of the universe.
So you can see this is not a matter of a simple mechanistic experiment, which is why I am not at this time trying to prove Spectrum Science is true. I believe the math will eventually do that for me.
 
I guess you are from an orthodox intellectual background with all the territory it goes with. What is "peculiar" is a matter of perspective. Since I have saturated myself in the entire science of Spectrum, the methodology seems second nature to me. An outsider would normally see something outlandish, this is tough on the credibility factor. To be really understood would take a LOT of learning Spectrum Science for even the most intelligent of entities, so most likely nobody will be willing to invest that much time and will simply dismiss it as "well developed delusional system"
