This is an interesting article, which touches on a lot of interesting musical topics. However, it's wrong on so many levels that I would never recommend it to someone who wants to understand music theory. I'll try to summarize.

I spent a long time researching where Western music "comes from". One important thing to understand is that the key feature of Western music is harmony. This is not the case for most other musical traditions. Harmony comes from a layering of independent melodic lines (called voices), such that they evolve in ways that create and resolve tensions. This is called counterpoint.

The ways in which these tensions resolve are called cadences, and classical music was all them. Musical form arises around how a piece of music is organized to have an arc (and arcs of arcs) that leads to a cadence. It's kind of like how there are only a few basic narrative structures in storytelling, yet infinite variations in types of stories.

The tension between the sounds in concurrent melodic voices emerges from the structure of the sounds. Harmonic sounds, like ones produced from wind and string instruments, sound good (consonant) when their fundamental frequencies are simple ratios. This is largely because of how the human auditory system works.

Our scales and chords come from picking collections of notes that approximate simple ratios. We deal with approximate ratios using nth-roots for two reasons. First, simple ratios don't compose well -- stack them (i.e. multiply them) and you get ratios that aren't so simple. nth-roots do stack nicely. Second, it lets us merge nearby flat and sharp notes. This wouldn't be possible if we used real ratios. That merger, known as enharmonicity, lets us do all sorts of cool compositional tricks that are generally considered more worthwhile than the slight improvement in sound quality we'd experience by using the real ratios. There are various ways to pick just which notes merge, but by far the most popular approach is to use 12 notes.

So, this is where we got our notes and scale from. This happened around the year 1800, give or take a couple decades.

The history of Western music since that point in time largely revolves around coming up with new ways to play with those 12 notes, in many ways erasing the musical features that caused the 12 notes to emerge in the first place. This is why the system of note names, with the flats and sharps, feels rather arbitrary today.

Unfortunately, there are not a lot of great resource that tell this full story. The two books I found most enlightening in piecing together the "real story" are:

- Tuning, Timbre, Spectrum, Scale: https://www.amazon.com/Tuning-Timbre-Spectrum-William-Sethar...
- A Geometry of Music: https://www.amazon.com/Geometry-Music-Counterpoint-Extended-...

Pay attention: "you just don't see it" == "they take it from the company"

Your assertion that a company wouldn't pay more without a recruiter makes no sense. Particularly if they're sourcing candidates off a trusted source

Ps. I suspect your comments get downvotes because they come across as rash and not very well thought through.
The failure of iTunes is intrinsically linked to the unsuitability of WebObjects as a modern application framework.

iTunes isn’t bad because Apple is inept, far from it, but to make it fine at this point would require a rewrite and I assume at Apple there is a tradeoff between “Is this crappy to use” and “Well, does it at least work?”, with the latter being a stronger motivator (or in this case, demotivator) of change than the former.

> "ideal programs" that halt when any program input to them halt

Nit, but this can certainly exist. "Accept program as input, run input program" is one such program.

You can always (eventually) halt and say "this halted" for any program that halts. The hard part is distinguishing "this will never halt" from "this has not halted yet", and that will always be impossible for some inputs.

The point isn't that people aren't capable of being rational. If they read the question carefully and think hard about it, of course they'll be able to figure it out. But that takes a lot of conscious effort.

The point is that people aren't often willing to put in that effort, so they default to intuition. What's more, they might not even realize they're doing this.

Your second point seems pretty valid, and to address your first point:

"There are multiple cues to the same information. Everything has both a symbol and spatial element, for all kinds of thinkers."

Indeed, in addition to the spatial length of the notes, there is also a symbol next to the notes denoting their life. You can see this on the linked page, in the second section. (Next to "Intuitive.")
> This is not the case for most other musical traditions.

Do you have examples of musical traditions that don't do this? Both the Indian and Chinese musical systems do something similar.

I'm not really sure if this post is "wrong". It gets the chronology mixed up a bit -- talking of twelfth roots of two before talking about ratios, but I thought that was just done to help explain things by reverse-engineering them. I don't think it claims that the notes "came from" roots of two.
Well, the first figure: frequency is NOT the period, and amplitude is not that. I guess there are lots of errors in the text if the first figure is completely wrong.

I don't buy that. Spiders can't beat a human at Go. Sure, they weren't evolved to do that. But how many generations of selective breeding do you think it would take to evolve a spider that could beat the best humans at go?

Whereas if you made a spider hunting video game, I bet researchers could train AI's that could beat it within a few months. Video game playing has actually become a big area of research recently and we will soon see deep nets that can beat starcraft and other real time games that take planning and skill.

The Chinese Room is not a valid mental experiment because it tries to evaluate the language understanding ability of an entity that is not an agent, then compare it to that of real agents.

The room is not grounded in reality, doesn't optimize behavior in order to maximize reward (is not intelligent) and doesn't have any external constraints (need to survive and reproduce) that human have. So obviously, it can't develop the same understanding as humans.

Also, the "codebook" in the Chinese Room was just a weak word, in reality it means deep neural networks with generalization power, not just a hash lookup. Searle has difficulty in understanding how generalization works in machine learning, so he is reducing it to a caricature word.
The primary value I derive from recruiters is them being a trusted source with direct contacts to hiring managers, so that I can get interviews quickly. I do not need scheduling or resume advice.

Moreover, 10% from me is quite different than a fee paid by the employer. The employer fee does not necessarily have to come from my pocket, as payscales could be standardized or deduced and negotiated. But the 10% definitely would cost me.

It's not merely sight reading that relies on the existing notation, jargon, and theory.

Every element of Western music builds on the same building blocks. Western harmony, as taught, relies on understanding chromatic and diatonic harmony; the author did a nice job figuring out and explaining the compromises inherent in equal temperament (without knowing about how ratios and tuning worked before equal temperament; people didn't always fudge the ratios to make them work out the same across all keys), which is cool. But, he still doesn't actually know much about western musical harmony, as evidenced by the assertion that C Major and A minor are "the same", because they share a key signature and the same notes. Had he known that equal temperament is a moden-ish invention, he might have also figured that C Major and A minor actually have (slightly) different notes if your instrument is tuned specifically for that key rather than with equal temperament.

In short, he's just not done learning yet. Most musicians and composers never really are, as it is a vast subject. And, what he's calling "music theory" is really more "equal temperament tuning math" with very little theory.

Not to say it's not interesting and well-presented. It may be useful for non-musical nerds to see it presented in this way.
Although sometimes the lack of consent to be treated is the issue, I think the far bigger issue is underfunded/understaffed mental health services. I think the consent issue is a bit of a distraction from that.

FWIW, I think you are correct. Companies are interested in keeping people in the same paygrade at similar pay. People talk, after all. They cannot pay someone more or less based on whether there is an initial upfront recruiter fee, as the employees will find out soon enough and threaten to walk.
"the way the French decided to fight German panzers with mounted cavalry in WWI"

Quick note: I think this is historically inaccurate. In World War One, the Germans had essentially no tanks, unlike the British and French. In World War II, there's a popular rumor that Polish (not French) cavalry forces charged German tanks at Krojanty, but this is itself a myth (the cavalry attack was against infantry, tanks arrived afterwards).
Switzerland and Norway would come to mind. Norway has a large sovereign wealth fund created just for the purpose of keeping up an income stream once North Sea oil runs out. Germany and Japan are possibly the only ones close to the US's size and scale in population (3-4x smaller).

>The whole point of Bach’s Well-Tempered Clavier music is that tunes transposed to different keys sounded different, so you needed to compose the music specifically for each key.

that sounds wrong. tranposing a piece into the instrument's natural temperament will make it sound better. TWC doesn't do that, you play a piece of any key without needing to transpose anything, because the piano is equally-tempered and has no natural temperament (without going into how "well temperament" differs from "equal temperament").

for instruments whose tuning can be changed with technique, like string instruments (even fretted ones), wind, reed and brass instruments you can revert to playing a pure temperament in order to make certain harmonies sound "better", which is what we sometimes did - for example, by getting the minor third instruments to play slightly flatter - in a symph band.

If that is indeed the case, I really can't blame them. Who would want a likely mentally unstable homeless person living on their property? I'm sure the expected property damage is substantially higher than from a standard tenant. Forcing landlords to take "vouchers" for high-risk tenants is essentially forcing much of the cost of homelessness away from the city and onto the landlords.

"2. Learn your intervals, and learn Solfege. If you're a musician, you already know these things in principal, even if you don't know the words or the terminology. In particular, you should be able to "hear" the distance between Do-Mi-Sol without too much difficulty, because you hear those distances in music a lot."

I believe the Solfege named intervals (Do-Re-Mi-Fa-So-La-Ti-Do) are only taught as a historical oddity these days (or maybe used more in classical training?). All of my musical instruction, at the high school and college level, used numeric interval names (1-2-3-4-5-6-7-8). Most of the serious musicians I've played with also used the numeric scale rather than Do-Re-Mi. We learned how to sing Do-Re-Mi, "Just in case", but we never used it.

Were you taught in the US, or somewhere else? Maybe it is a regional thing.
