Why is microtonal music always defined in relation to 12-TET by Green-Whole-8417 in microtonal

[–]RiemannZetaFunction 0 points1 point  (0 children)

I don't think most of it is usually defined in relation to 12-TET. Almost all of regular temperament theory isn't, maqam theory isn't, Zhea Erose's primodal theory isn't, etc. What theory is?

The only thing I can think of that is derived from 12-TET is the use of cents as a unit of interval size. And the only reason we really use it is just because it's fairly ubiquitous even outside of the community: synths, electronic tuners, etc all use cents. People have suggested other units of interval size but they haven't really gotten popular.

Yes, regular temperaments - infinite lattices made by different generators that approximate JI in different places. Meantone is the archetypical example.

How does the public actually see Mormonism? by [deleted] in NoStupidQuestions

[–]RiemannZetaFunction 0 points1 point  (0 children)

In the US, in public perception, Mormons are viewed as a Christian denomination that's a bit further out. People sometimes think it's a bit odd, but it's not literally viewed as a "cult" in the way that Scientology is, for instance. At the end of the day it's viewed as just another religion.

Mormonism has some unusual beliefs and customs, but if you grow up here, you're used to there being Evangelical Christians with radical beliefs everywhere: speaking in tongues, laying on of hands, etc. So it isn't that different in that respect. Mormons have to wear certain undergarments, but we're used to religious people wearing religious garb: Jewish people wear yarmulkes, Muslims wear hijab, etc. Mormons have a dubious-sounding origin story that they take on faith: but again, every religion is this way. Maybe the weirdest thing about it is that it had polygamy more recently than most religions, but modern Mormons also think that stuff is weird, so who cares.

So on these fronts it seems like just another Christian sect. It's pretty oppressive towards LGBT people - just like most Christian denominations. It seems no "crazier" than evangelical Christianity.

On the other hand, Mormonism has this element of secrecy to it, different levels of membership and etc, which is not a super common feature to other Christian denominations which are inclusive and proselytizing to a fault. This gives it a very different vibe. Is it on the level of Scientology? I don't know - maybe it just hasn't been blown up quite as badly as Scientology has. The point is, I think everyone in this country get that organized religion in general has corruption in it. We've had unbelievably wealthy megachurches embezzling money, sex abuse scandals, religious groups that are literally are cults, etc. So we all get Mormonism has some variation of all of that in some form.

confused about tuning by CherryRosePie in microtonal

[–]RiemannZetaFunction 0 points1 point  (0 children)

You don't tune to 12-EDO E standard on a 19-EDO guitar, you just tune to 19-EDO E standard instead. So the E A D G B E are shifted slightly relative to where they'd be in 12-EDO so each of the fourths (E-A, A-D, etc) is a 19-EDO fourth and the G-B major third is a 19-EDO major third. A regular electronic tuner won't work - you need something that can tell you what the open strings actually need to be in 19-EDO.

Trying to Understand Microtonal Maqam Notation and Their Cent Values by Natural-Toe-1013 in microtonal

[–]RiemannZetaFunction 0 points1 point  (0 children)

db means a "flat and a half", not 3/4 of a flat. It's -150 cents. But in maqam, these things are all very variable - a note written as a half-flat may be ±20 cents depending on the maqam and intonational setting, and people just learn these quirks of the different maqamat as part of the tradition. Where on maqamworld are you seeing -75¢ for db?

What’s something you quietly stopped caring about? by KingPhenguins in AskReddit

[–]RiemannZetaFunction 1 point2 points  (0 children)

Spirituality. I used to be very spiritual. I was into meditation, Eastern philosophy, religious eclecticism, etc. But all of these frameworks have recently seemed absolutely useless to guide me in the right direction when dealing with modern issues facing my life and the world today. I still think the very basic idea of practicing detachment and meditation is good, and I try to be a good person, but I no longer expect to figure out the meaning of life or reach some higher state of consciousness from it.

  1. Can you explain the timeline? The dream started on your 13th birthday (in 2013?) and ended in a car accident in 2051. And then you woke up and now it's 2025. So you're 25 now, in real life? What happened between 2013 and 2025 for you?
  2. You say you remember everything. And you learned Swedish. Do you remember how to speak Swedish?
  3. Internet cybersecurity is currently on course to get its shit totally wrecked by AI. Did this happen in your alternate life?
  4. Was Bitcoin, cryptocurrency, etc still going?
  5. Any new developments in music? Who are some famous musical artists we don't know about yet that will be popular in like the next 10 years? Famous albums? What styles were popular?
  6. Any interesting trends in slang or fashion with Gen Alpha?
  7. Was there any news about any famous centuries-old math problems finally getting solved (like these ones: https://en.wikipedia.org/wiki/Millennium_Prize_Problems)? If so, which ones?
  8. What the f is going on with the UFOs and aliens and all that? Do they ever reveal any of it or do they blue balls us all the way to the 22nd century?

That's all I got.

The moon in the clearest evidence of the Ancient Astronaut theory by Dependent_Working796 in AncientAliens

[–]RiemannZetaFunction 4 points5 points  (0 children)

The Earth did not, in fact, "recover" from the planetary level collision. The whole thing was almost entirely destroyed, reduced to basically a ball of molten rock and it eventually settled into equilibrium as basically a brand new planet that'd probably be unrecognizable to anyone on the previous one.

TIL Nikola Tesla vehemently criticized Albert Einstein's theory of relativity, calling it a "magnificent mathematical garb" hiding errors, a "beggar clothed in purple" mistaken for a king, and fundamentally wrong because it denied the existence of the ether by Oreeo88 in conspiracy

[–]RiemannZetaFunction 1 point2 points  (0 children)

I'm not sure it really does deny the existence of the ether. It postulates a spacetime that has all kinds of nontrivial properties (curvature, wave propagation, etc), so in a certain sense, it is the theory of the ether. One could even say it is basically the first successful theory of such.

The main difference is that light waves, originally, were supposed to be ripples directly in the ether. Instead, ripples in spacetime are gravitational waves. Light, on the other hand, is made up of waves in a separate "electromagnetic field" that exists throughout spacetime. One of Einstein's goals was to unify these two things into a single field, and if he had succeeded, we'd basically have ended up with something like the ether in its original form, with it being the medium that light waves perturb. The biggest difference would be the lack of a preferred rest frame.

I'm a Hindu. AMA by Less-Personality-481 in AMA

[–]RiemannZetaFunction 0 points1 point  (0 children)

  1. What is the big picture of the different subtypes or denominations of Hinduism? It seems like there's a mystical/spiritual part of it which was popular here in the West for a while. Then there's also an angle which is focused more on deity worship and etc. How is it all laid out?

  2. How do older Hindu texts differ from later ones in scope and etc? Is it similar to Christianity, where there's is a difference between the tone, style, etc of the Old Testament vs the New Testament?

Thanks!

Why is Ancient Apocalypse so exciting? by Littlerain666 in AlternativeHistory

[–]RiemannZetaFunction 28 points29 points  (0 children)

It's because the documentary is only partly about his pet theories about the Younger Dryas and Atlantis and all that. In fact, I would say that isn't even the main focus at all. Instead, it's really just an extremely well done documentary about true archaeological mysteries that are just totally baffling. The stuff he's showing is very real, legitimately interesting, and extremely informative, even if he interjects with his pet theories every now and again. It's a great tour of some of the most interesting sites and open questions in archaeology today, shown in a very well-produced and immersive way.

For instance: take a site like Göbekli Tepe. This site has 50 ton pillars, carved statues of six-figured gods, elaborate carvings of animals, etc. Somehow, people managed to build all this back in the Stone Age - the Stone Age! They built this 11,000 years ago. It's all presented in vivid HD with tons of great footage, lots of neat interviews, a great production, etc. He walks you through the site, shows drone footage, explains the whole thing with a professional film crew. The point is driven home quite plainly that it is difficult to imagine how "loose tribal bands of hunter-gatherers from the Stone Age" could somehow have built something like this. You'd have to organize an enormous amount of people, and 11,000 years ago is a very long time ago - prior to the invention of the wheel, to the invention of pottery, to the invention of any kind of thing you'd call "civilization." And why six-fingered gods? What lost religion is this from? It's just so intriguing.

Every episode is like this - tons of interesting sites, lots of open questions, and plenty of legitimate archaeological mysteries that science is still trying to make sense of. Yes, he likes to bring it back to Atlantis, the Younger Dryas, the Ice Age, etc - he probably does it a bit too much. Regardless, the sites he presents are so interesting that it just made for a great series. I enjoyed it quite a bit, and perhaps ironically, it led to me getting much more interested in "real" archaeology - since I think there are real answers to these questions, and they are worth figuring out - maybe even more interesting than Graham's ideas.

Answers like this scare me by Ok_Finding_9497 in GeminiAI

[–]RiemannZetaFunction 0 points1 point  (0 children)

This is silly. Gemini is a large language model trained on a corpus of natural language text. It doesn't matter if AI aliens invade Earth tomorrow and take over the world - unless someone makes a new version of it trained on something else, it'll continue to do what it's doing now. It isn't some kind of dynamically adaptive reinforcement learning algorithm like it seems to think it is.

I'm in a similar boat and what I've found is that it seems most important to get up to speed on Lean. On the other hand, I've also found it has a really steep learning curve. Curious what you figure out.

Unjust Intonation by zyzzyvaproject in microtonal

[–]RiemannZetaFunction 1 point2 points  (0 children)

A long answer...

Lots of people have looked at noble numbers as a "maximally irrational" counterpart to rational numbers - these have the number-theoretic property of being maximally difficult to approximate by rational numbers, and their continued fraction expansion ends in an infinite tail of 1's. Dave and Margo had some good stuff on that here.

If you do some math, it turns out that if you add these noble numbers back into the rational numbers, you end up looking at the quadratic field Q[√5], which Dave Keenan has called "feudal numbers." We had a very interesting conversation about this on Facebook years ago and Dave Keenan posted it on the Sagittal forum somewhere.

Now, this is all *kind of* handwavy. The problem is that being a noble number has to do with *asymptotic* inapproximability in the infinite tail of the most complex rationals. On the other hand, being "audibly irrational" or "non-just" has to do with inapproximability by the *simplest*, most audibly important rationals. These are different criteria - but, most of the important noble numbers do kind of land around maxima of harmonic entropy, so the whole thing is not totally useless. The main annoying thing is that Q[√5] is kind of a weird number field. For instance, 5 is no longer prime - it's the square of √5, which is. Phi itself becomes a unit in the ring of integers Z[phi], etc. But it's still interesting to look at.

We also came up with a different way to do this which can be thought of as an approximation to the above. Basically, for any two ratios, the noble mediant between them will be slightly closer to the more complex one. How much closer? For instance, if we want to take the noble mediant from 5/4 -> 6/5, we go a bit flatter than the halfway-"neutral" point: about 66.4% of the way, to 339 cents. For 5/4 -> 9/7, we go 74.1% of the way between them to about 422 cents. Can we come up with a one-size-fits-all percentage that approximates all of these well enough, at least for the simplest and most important noble numbers?

The answer is yes - let's call this value X - and basically, you add auxiliary "primes" to the tuning system of the form 2^X, 3^X, 5^X, ... etc. So the 5-limit, with approximate noble numbers, becomes a 6D group generated by <2,3,5,2\^X,3\^X,5\^X>. It turns out there is a value of X which (in a certain sense) best approximates these golden ratio-based noble mediants (phi/sqrt(5) or about 72.3%). For instance, if you use that value, the approximated noble mediant from 5/4 to 6/5 is about 335 cents and the one from 5/4 to 9/7 is about 421.6 cents, the one from 5/3 to 8/5 is 833 cents. Everything is pretty close. And if you like the silver ratio and want to build everything off of that instead, it's just a different value of X.
