@ dR-Green. Great that you could put that demo together! It does help and highlight the difference between equal temperament and Pythagorean temperaments. The C and fifth does sound more harmonious, but to me often the harshness actually sounds good too.

Glad it helped, I'll upload a better video tomorrow for a full audio and visual representation, currently rendering and I'll be asleep by the time it's done. In the meantime, in electronic music there's nothing more boring and flat sounding than pure unchanging waveforms so the dissonance can be used as an effect or to create the sound itself, as well as a rhythmic component etc just from two pure waveforms, which is a good starting point for making more complex sounds, and somewhat more natural sounding in that it changes over time rather than being a perfect digital reproduction of each cycle.

On dissonance and the equal temperament and Pythagorean scales







Consonance and dissonance - Wikipedia, the free encyclopedia

A piano tuner uses the concept of dissonance as an indicator in order to tune the piano. When two oscillating strings are not precisely in tune with each other, what may be perceived as phasing or modulation effects occur, also known as beat frequencies. As each key on a piano consists of 3 individually tuned strings, each string must be perfectly in tune with the other two associated with the same key in order to sound good. In order to achieve this, the piano tuner makes adjustments until there are no perceivable beats or phasing. Only then is the piano key in tune with itself, and this is how incalculably fine adjustments are done by ear. Needless to say a piano tuner isn't considered a professional until he has many years of experience under his belt.

This is the concept that also allows us to look more closely at the different scales and ideas put forth in Eric's latest presentation "Power of Aether as Related to Music and Electricity".

For this purpose, the files 12_TET.tun 12 Tone Equal Temperament and PYTH_12.tun 12-Tone Pythagorean Scale listed in post #2371 are loaded as the scaling system for LinPlug Albino 3, which is a software virtual synthesizer plugin. It's possible to derive everything from the maths given in the presentation and to manually do everything, but someone has already done it for us and saved the mapping in a convenient file.

The beginning of the youtube video illustrates what happens when two oscillating sources are detuned from each other. Note the phasing effect, or beat frequencies and how the rate changes according to how much one oscillator is detuned from the other. The waveform used is a sawtooth, one single note C played, and two oscillators.

Next, C and the fourth is played using the equal temperament scale, and then the same with Pythagorean. Then C with the fifth in the same order. Note the same dissonance that was heard when the two oscillators were detuned. This time only one oscillator is used, the phasing or beat frequencies are the result of the fact that the equal temperament keys aren't precisely in tune with each other. Note how various frequencies appear and disappear displayed on the spectrum analyser. With the Pythagorean scaling, the keys match the natural harmonics. A sawtooth waveform is used with a single oscillator here again.

Then the waveform is changed to square, and distortion is added to emphasise the harmonics. Now the dissonance speaks for itself and becomes glaringly obvious.

You might experiment with Pythagorean temperament ideas with you own music production?

I have stood in front of my friends’ invention / device which consists of ten pairs of speakers, (twenty in total). Each pair of speakers has its own amplifier and each amplifier is driven with its own discrete frequency all controlled from a PC and certain software. All of the frequencies are derived and based around the golden ratio. The reason for so many speakers is because one speaker could not physically reproduce the complexity of the sound. Standing in front and listening to this device for a time really moves you. There are nodes of sound that can be found by moving around in the space between them. It becomes a little addictive, seems to have strange effects on ones’ consciousness etc.

My friend is also a fan of Eric and his work, so I’m sure he might try and develop sounds with his device based on Pythagorean temperament.

Hi dR-Green:

I had a chance to watch the Eric's CRI video twice. A couple of thoughts:

1. Had Eric told us at the beginning not to worry about the extra coil and the importance of a very good grounding/ground antenna system under the experimental set up we would now have more people involved in the CRI with good results. I for one will start my experimentation again with the CRI based on the new instructions.

2. Once the lighting of a small bulb is achieved then we are ready for the experimentation with the extra coil.

3. In the video demonstrating the 12,000 feet long underground antenna's effect on AM radio reception it seemed to me that the underground telephone wire's orientation was not important and I also gathered that the wires were insulated and grounded on both ends. The reception with this set up was fantastic.

4. What is the significance of two 6,000 feet long wire? Just as a curiosity, what would be the reception with the same AM receiver if a 12,000 feet long above ground antenna is connected to it.


5. How the effectiveness of this telluric antenna changes with buried depth. Is there any data for that? I know Eric gives a range of depth in the video but it is not clear if the numbers are "out of the air" or based on some actual measurements.

6. Is it necessary for the in ground antenna to be a 12,000 feet long straight line? What would be the result if this 12,000 feet wire is laid out in a zig-zag fashion with a coupling coil in the middle of it. That is 100 feet lengths back and forth 60 times then the coupling coil and then again 100 feet lengths 60 times with grounding rods at both ends.

7. Can the superiority of the underground antenna be demonstrated with shorter length wires? What if the two shorter run is perpendicular to each other, that is at the end of one wire run the other wire run starts perpendicular to the first one?

8. The reason for the questions in paragraphs 6. and 7. are to possibly encourage an experimenter who does not have property with 12,000 feet straight runs to build a reduced size underground antenna system to experiment with.

Your observations about flowing water are very reveling and I can share your amazement. At one time in my life I was a white water raft guide on up to class V rivers and I am somewhat familiar with river hydraulics. I had the chance to observe how moving water creates formations that may be permanent or momentary and how the power of moving water created maybe a standing wave or a hole that is rotated upstream against the current. I also spent lots of time fly fishing in fast moving mountain streams and again an interested observer could see the endless formations that flowing water can display.

@ Nhopa: Your questions were asked of dR-Green but my answers to you from your list is as follows:

1, Eric did say it from the beginning, (I’ve mentioned it too) the Extra coil can be omitted until one has mastered the secondary coil alone. This for both CRI and TMT / CIG rig set up. Extra good grounding for receiving telluric signals is indeed essential. (Remember the video: 24 ground rods into a salt marsh connected to a massive copper bus)… Anyway good that you’ve picked this up now.

2, Likely, a really small grain of rice bulb with secondary alone.. Then experiment with an Extra-coil.

3,4, ? Not sure.

5, Not sure either about the effectiveness against depth. I don’t think any data from Eric has been given. It might depend on soil type or even surface area in contact with the ground. So a larger diameter pipe should work better than a thin one, given the same length. - I asked “how deep” once and Eric simply said how deep can you go? The Earth is hollow. - Most likely the deeper the better.

6, Likely not optimised by a zig zag, but sounds as if it might still work?

7, Don’t know. Experiment and see.

8, Most people don’t have a large property, so any manner to adapt to your own situation would be acceptable. Let’s hope more people do get involved.

On dissonance and the equal temperament and Pythagorean scales

An unstable tone combination is a dissonance; its tension demands an onward motion to a stable chord. Thus dissonant chords are "active"; traditionally they have been considered harsh and have expressed pain, grief, and conflict.

The concept of dissonance does not belong to the domain of harmony as it is presented us by Nature [harmonic series], but is derived from voice leading [guidelines], which is an essential constituent of Art.

In Western music, dissonance is the quality of sounds that seems unstable and has an aural need to resolve to a stable consonance.

When two oscillating strings are not precisely in tune with each other, what may be perceived as phasing or modulation effects occur, also known as beat frequencies.

Hi dR-Green:
Thank you for the information, I subscribed for the video.
The waves on the beach are indeed interesting. It seems they form over the sand ripples on the bottom then some of the water flow goes under the standing waves, giving them a spin against the water flow and the rest of the water flow goes over the standing waves. This split water flow perhaps create a low pressure zone in front of these standing waves thus make these waves move upstream while they slowly rotate toward upstream. Just a thought.

Flowing water is quite a fascinating situation, which is particularly dynamic on a beach because you can do things like poke a stick into the sand and watch how it all behaves as the water flows around the stick etc. The water also carries sand away and deposits it further down the stream, so the flowing water creates the sand ripples which create waves, but the waves also create the sand ripples through flowing over what starts as a flat surface, nothing is static or rigid about the process.

Anyway, one of life's coincidences is that this then presents itself:

This video is a bit of nature I filmed on a beach a couple of months ago. Apparently when the water started flowing too fast it would impede itself through forming standing waves and causing the water to flow in the opposite direction in the turbulence, at the same time waves intermittently/spontaneously form and travel back up the stream seemingly unaffected by the commotion and then vanish.

I did not seen Eric's CRI presentation but I have the sketch Eric provided for us back in 2012

It's good and goes into more detail, available here

Crystal Radio Initative

[dR-Green]

Are you saying it does not matter if my ground resistance is 10 Ohms or 600 Ohms?

I'm not saying it doesn't matter, I'm saying it doesn't matter as long as you can't accurately measure it and then improve it. Just do the best job you can and there's nothing more you can do about it, it will be the best you can get out of the location whether you've measured it or not.

I live in a 100 year old house so the mains earth is actually earthed outside. That's how I receive my own transmissions off the toaster!

Grounding

Hi dR-Green:
Thank you for the video. It seems these guys did not check the published minimum recommended distance from buildings, which is 8 feet.
It is also interesting to note that Tesla was always very concerned with high ground resistance. I wonder how he measured ground resistance in Colorado Springs.
Let say I will run tests to try to duplicate Tesla's Radiant Energy patent. Are you saying it does not matter if my ground resistance is 10 Ohms or 600 Ohms? I will expect positive charges from my collector and negative charges from the earth into the capacitor, so ground resistance will influence the result. What is your measured resistance from your house "earth" to an outside ground?
As far as driving rods down 8 feet into the ground it is not difficult in the desert, but the heat is something else. Keep cool.

[dR-Green]

Hi dR-Green:

The reason is given in my reference. These guys ran tests and the conclusion was that proper rod spacing is 2.2 times the rod length, anything closer is just waste. Also I am aware the various test methods but in order to use them one needs expensive instrumentation and elaborate test set up.
I did not seen Eric's CRI presentation but I have the sketch Eric provided for us back in 2012 that shows a star radial system with a center rod plus 16 rods on a circle of 20 to 40 feet diameter. Considering my reference, 10 of those rods are useless, waste of money.
What other alternate do I have to measure earth ground to house ground resistance?
I will place my 5 grounding rod in accordance with the reference's recommendation. One in the center and 4 around it, spaced at 17 feet apart. I will report back on the result. Currently our temperature runs around 43 C, 110 F so I can do only one rod per day.
As a side note, if one of you in the forum has building plans for a sophisticated VLF or PI type metal detector, please let me know.

Unless you already have the expensive equipment to measure it, then the easy conclusion is that it doesn't really matter. It is what it is so getting some measured number is only good for personal satisfaction or information. Unless you intend to dig it all up and make changes upon finding the numbers too high.

Also bearing in mind that you can't really measure the resistance of your arrangement at Point A without using an equivalent arrangement at Point B, otherwise it will only be as good as the worst connection you have, so it mostly defies the point as it won't give you any meaningful reading.

You can use a hammer action drill or pneumatic drill type contraption for easy earth rod installation.

[dR-Green]

But the reference I gave above tells that the individual rods must be no closer to each other than at least 2.2 times their length.

Is there any particular reason for that? I'm not sure that a multimeter in resistance mode is an accurate way to measure the earthing, there's some info here

http://www.esgroundingsolutions.com/...ystem-testing/

A house is considered to be adequately earthed with a single 1-2 metre rod, so that will be nowhere near what you're after.

Have you seen Eric's recent CRI video? There's good info on earthing in that. Basically you want to cover the greatest area possible with the collective earth rod arrangement.
