I haven't been participating on the forum for a few months very much and I apologize. But about two months ago, I just decided to see if I could clarify the 'acoustical levitation of rocks' business for myself, and dived into the transcripts, YT, elsewheres. I made some pretty major connections (for me at least) and I thought I was really getting somewhere when something happened and I all of a sudden went on a downward spiralling tangent that took me until (maybe) last week to recover from. I do feel better now but it was a very strange month. Anyway, I've got so much to go organise that I'm breaking it up to lighten the load.
One of the areas that I looked into was the 'sub-tones' reference made by the C's.
(Pierre) I have another question if we can change topic. There is this French scientist who discovered those Paleolithic pestles made of rock. For decades they thought they were used to crush seeds or whatever. By chance, he dropped one - and he's a musician - and he found that it sounded good when it hit the ground. So, he started to analyze all these pestles. He found that each of them was tuned. Each of them generated a perfect note. Now their hypothesis is that the pestles weren't pestles, but a musical instrument. Are these pestles only used as musical instruments?
A: No, not even close. Healing tones produced when struck in correct sequence and combination.
Q: (Pierre) So it means some kind of music? Perfect tunes? If you play the right notes in the right sequence... And the right combination... Music can be healing.
A: Important that the tone is accompanied by subtones and frequencies that are natural to the stone and "speak" to the cells in the body.
Q: (L) So I guess you can't just play the music.
(Pierre) No, it's more elaborate than that. But it means a great amount of knowledge...
A: Notice the specific stones chosen for Stonehenge.
There's also this section from Dec 1, 2018:
(Pierre) About frequencies... In a previous session, we mentioned this prehistoric stone that was perfectly tuned. The C's said that it was not a musical instrument, but instead for healing. They said you can't heal with a single tone, but with the proper tones and sub-tones. You need the right combination. I guess past civilizations had this knowledge. Today in our modern world, are there remnants of music or song that convey part of this knowledge?
A: Yes
Q: (Pierre) Oh yeah? Which one?
(L) Which one what?
(Pierre) Which song or type of music is closest to the tones and sub-tones that have those healing properties?
A: Gregorian chant.
As a side-note, I'm just going to add this section from Nov. 7, 1998 because of a little tie-in:
Q: Alright: 'mathematics converts to sound in geometric measurements.' When we set up these figures...
A: Imagine an interlocking triangular mosaic in three dimensions.
Q: When one wishes to apply this, does one somehow... Is the sound inside one?
A: It is all around and through you.
Q: Is it a sound that can be perceived with the physical ears?
A: Yes.
Q: What frequency?
A: Not issue. Tone.
Q: Tone and...
A: Vibratory pitch.
One of the definitions for 'tone' is, “A recitational melody in a Gregorian chant.” It's just an interesting tidbit. And for
clarification, 'vibratory pitch' is frequency, and 'tone' is the quality of the sound/note/music, the
emotion, if you will.
Ok, so, I don't know which Paleolithic pestles Pierre was talking about but here are a bunch from Vigaya Vittala Temple (15th century) in Hampi, India. I'm sure many know about these pillars already, but just in case:
There are also other stones from Hampi that make notes when struck.
These types of 'singing stones' are known as lithophones made of
Phonolite, from the Greek word meaning 'sounding stone'.
In this video, Praveen Mohan visits the site known as the
Bell Rock of Kanchanagiri (Temple) Hills, Lalapet, India, known to locals as 'Shiva's musical instrument'. I ran into this video early on, and he said several interesting things, but the one that I'm focusing on here is at 8:20:
Ancient Indians used these sonorous rocks for a specific reason. They would basically lie down on it and somebody would tap on the edges. And this procedure would continue for hours. They believed that this would heal their body and their consciousness.
Now, none of the above examples deal with sub-tones. From the first quote from the C's, in order for the rocks to provide healing, sub-tones that 'are natural' to them need to be a part of a combination. If you do a search on the forum, you'll find that there is much discussion for 'overtone(s)' but almost nothing for 'sub(-)tone(s)', so here's a bit of what I've found.
There are many videos, actually, to be found on this topic. Here are a few descriptive videos from people who can
sing in the sub-harmonic range which can be accessed through a technique known as ‘vocal fry’
.
As a start, here is an eleven year old video from BBC News on ‘vocal fry’, for those who are not familiar. It's not the best video, I don’t know if this is meant to be a satire or not, but I’m posting it to show a 'real world' application and also because at 0:37 it briefly shows what the throat looks like making the sound.
Here is a short tutorial on sub-harmonics from professional singer Tao Yang (Bass2Yang). He has several tutorials that are more in-depth.

David Lawson has many videos on singing sub-harmonics, but he kinda gets repetitive. This one, however, was quite interesting, I thought, and for sub-harmonics (example #2) he says this at 2:19:
In order to enter your "sub-harmonic register"- that's what we'll call it- you have to allow your vocal folds to vibrate at two different rates- two different but consistent rates. Let me explain. For the first sub-harmonic, you need a wavelength ratio that is formed by a 'perfect 5th'. Let's take, for example, 'harmonic D2'. we start with a 'fundamental D3' then we allow our voice to relax into a certain/sort-of 'organized fry'
[remember 'vocal fry']. In doing so, one of our vocal folds stays on the D3 while the other vibrates an A3, a 5th above. The result, or the resultant pitch, is a sub-harmonic pitch one octave below- a D2. This technique is not isolated to vocals. It is used by organists worldwide to produce
zero octave pitches that aren't on their keyboard at all. Other instruments like tubas, trombones and trumpets can use this technique as well, called '
pedal tones'.
Also, pay special attention to example #5. It's a strange technique of producing sub-harmonics through ‘ingressive phonation’ (inhale singing (!)) which produces the lowest notes I’ve heard yet. I mean, wow!

The thought came to me that if one was to master the art of both exhale and inhale techniques, it could produce a continuous sub-harmonic cycle.
Also from David Larson is his video on singing eight notes at the same time. I don't know how effective this is but I could definitely hear at least three notes at once.

I'm now going to go in a completely different direction with this overly long (26:19) video. The guy is trying to prove that the megalithic builders of the past had no problem moving massive stones around. The first part deals with vibrations. He made a very crude set-up using a speaker as a vibration table. In a little pan, he subjects a steel cylinder, a brass cylinder, an aluminum cylinder and a chunk of granite, all weighing 128g, to 120 Hz vibration. They all move around a little bit but they're difficult to push though the granite is easier. He then adds a little water and goes through the test again. The granite moves much easier whereas the metal cylinders are still difficult. Then he ran the test again at 70 Hz. The metal cylinders, again, moved with difficulty but the rock moved more freely. The second part of the video deals with an equally diy setup trying to show the electromagnetic properties of granite.

Anyway, what caught my attention was the 70 Hz frequency effect on the granite chunk and I wondered if there might be a connection with sub-harmonics?
