CORRECTIONS AND CLARIFICATIONS - READ BEFORE COMMENTING:
This video has blown up, and was never expected to reach such a large audience. I've become acutely aware that I may therefore be widely spreading misinformation - partly through simplifications and omissions, partly through my own ignorance - and want to correct that as best I can. This list will be updated as I'm inevitably corrected further.
0:09 - Pythagoras was born (if he was born at all) on the Greek island of Samos, but spent much of his life in colonies in Italy. Supposedly.
1:36 - I want to emphasise again that all the stories I tell about Pythagoras in this video are legends, including the fact that he "invented" a system of musical tuning at all. Like many Pythagorean discoveries, Pythagorean tuning likely appeared many times around the world throughout history.
1:57 - Sources disagree on whether it was the hammers or anvils that varied in size, and whether they had twice the dimensions or twice the weight.
2:15 - Some people noted my sine waves sound a bit distorted, maybe even triangular. They absolutely are sine waves, but I did add some reverb for the ambience. Also TH-cam compression is a thing. So they perhaps aren't totally pure.
4:15 - I didn't mention that size of hammer is *inversely* proportional to frequency. Size determines wavelength, the reciprocal of frequency. Everything I said here is true, but thought I'd add this just in case you thought I meant the larger hammer produced the higher frequency.
6:03 - I had not explained enough by this point in the video to introduce diatonic scales in a natural way, so saying 'it's the fifth because it's the fifth note of the diatonic scale' would not have been possible. Instead, I made a bad joke. Please stop taking this as evidence I don't know what I'm talking about. This comment is filled with more legitimate claims to that.
7:29 - Due to limitations with the VST I used, I could only tune this instrument's notes to the nearest two or three cents. So none of the plucked notes are perfectly Pythagorean, they're all a tiny bit off. All the sine wave notes I use are however precisely in tune as I made the VST for that myself.
7:30 - My version of Pythagorean tuning starts with a base note at the lowest frequency and works up. In reality, some Pythagorean systems start with a base in the middle and create equal numbers of fifths above and below. The harmonic relationships in these systems are functionally identical.
7:36 - In case you were wondering why all the intervals of the same ratio are the same length when they're being multiplied, this diagram is logarithmic. Multiplication corresponds to addition on this diagram, so multiplication by equal values corresponds to equal length intervals.
12:06 - Obviously x = y = 0 is a solution, but then you'd have a scale with only one note. Hardly useful, so I left that out.
12:15 - There are also systems with 53 notes per octave that do about as well as 12, and many other alternatives.
12:55 - Pythagorean tuning (and meantone temperament) are examples of a larger class of tuning systems called Just Intonation, where note intervals are defined to be rational multiples of one another. Pythagorean is just the version where the multiplicative ratio is a fifth. Many musicians in this period used other types of Just Intonation, but they all suffer from similar issues. Further, in the original Greek period, nobody was using polyphonic harmony, at least in the modern sense. Grating dissonances mattered less as a result. Harmony only became a more concrete thing later, which necessitated the introduction of meantone temperament. However, the equivalent to the wolf fifth in meantone is more of a problem, and that version of the wolf fifth is the more common example than the Pythagorean one in this video.
13:11 - The Catholic Church DID NOT ban tritones. I've since learnt this is a widespread myth that even some of my sources fell for. Made even worse by the fact that I mixed up tritones and wolf intervals in my script despite knowing they were different (but not that different). Massive brain fart there, I apologise.
14:33 - Stevin was only one link in the chain that led to equal temperament. Many people contributed to its development. I simplified it to one person to save time, but that was definitely a mistake. Also, as is often the case, a system like it may have appeared in China even while Pythagoras was alive.
16:23 - The piano was not the first instrument to use equal temperament, merely the one that popularised it. I didn't say otherwise in the video, but I didn't make it clear either.
16:48 - Oh boy. I got a lot of "well actually"s for this one. Some cases I knew already - instruments without fixed pitch, such as violins or even the human voice, can switch between tunings on the fly - but some I genuinely didn't know. Turns out many brass instruments play perfect ratios, and it's only by the skill of composers and performers that we don't notice. Plus, performances of older pieces are often tuned to pure ratios for authenticity's sake. All this does not detract from the fact that equal temperament is the overwhelming standard, and I still stand by my intended point that the average person in the Western world has so rarely been exposed to Just Intonation compared to equal temperament that it might as well not exist for them.
17:00 - Some have claimed this video is biased in favour of equal temperament (with a surprising and depressing amount of vitriol). I think it probably is, mostly because I am. But the system you prefer is entirely an artistic choice. Both are mathematically flawed compromises, I just prefer the one that gives more standardisation and harmonic flexibility. Modern musical hegemony agrees with me, but you don't have to. Electronic music synthesis means you can create music tuned to any frequencies you want. There is Pythagorean music out there if you choose to look for it, but beware: it often gets caught up in New Age, psuedoscientific mumbo-jumbo. If you find anything that claims Pythagorean tuning can heal physical ailments or that it's being denied from you as part of a global conspiracy, steer well clear. The Cult of Pythagoras is alive and well.

Damn dude. I was super psyched to pull a giant "actually" out of my otherwise mostly useless half a music degree, but you had to ruin the fun with your corrections.
You’re confusing pythagorean tuning and just intonation too. In a pythagorean tuning everything is generated from a fifth. So you get a big third from going four fifths up, and you can close it to a temperament if you want by flattening one fifth by the comma. Just intonation refers to the whole number ratio of pitches. Choirs intonate to just intonation all the time, because we feel the beating in our throats when singing. Of course within the limits of staying in key, because just intonation will cause a comma drift fast. And furthermore on the historie of temperaments, we tuned meantone until the 18th century because we favoured the pure thirds. Meantone too often gets confused with anything other than equal. But there’s a whole world of other temperaments, including well temperaments and pythagorean temperaments. Keep in mind that «just intonation» and «pythagorean tuning» are not explicitly temperaments, although you can build a scale that follows them from a fundamental. We tuned mostly well temperaments up until the 20th century. Equal temperament was not tuned or desired up until the 20th century.

Wolf interval actually sounds pretty nice
I was wondering how long it would take for someone to say this.
It's like a binaural tone, except for each ear.
@@OliverLugg I mean, I thought it sounded alright too...not the "perfect tone" were used to, but it sounds pretty alright by itself imo
@@jblakeplays2541 I don't have anything to back it up but I'm pretty sure it's because we've been conditioned with music that uses more harmonically complex sounds, just as with equal temperament. The dissonance of the wolf interval is nothing compared to say electric guitar distortion, which involves many more notes with angry ratios, and we hear that in everything these days. To people of the time though it was pretty offensive-sounding, since they were used to simpler instrument sounds.
@@OliverLugg So that's why I like really rough chord changes and minor keys
"i want to go to musical college to avoid mathematics"
The Lecturer :
Hard to avoid math if you go for a university or college. Although, there is this "social studies" thingy. Even though you don't avoid maths completely, you can get to use it a bit more loosely there, after all, it's never exact science when some level of human psychology is involved :)
math rock, about to destroy this man:
I had to take acoustics, an honours physics course, to get my music degree. It was torture
Yeah, music is literally just math but you can hear it.
The reason it’s called an “octave,” and a “fifth,” is because there are seven notes in the major scale.
When you reach the 8th note, you just go back to your root, so you achieve an “octave.”
When you go to the 5th note in the major scale, is a major 5th.
An octave (the “8th” note in the major scale) is 12 notes up…
And a 5th (the 5th note in the major scale) is seven notes up.
We call notes by their placement in the major/minor scale, not by how many semitones it goes up.
what the is major scale? 12 notes up what? you don't make sense. what is a note?
@@multiply67 a note is a singular sound that we make on an instrument. Think of pressing a fret and playing a string on a guitar or playing a single white key on the piano.
Music is comprised of 12 notes: A, A#, B, C, C#, D, D#, E, F, F#, G, and G#. The next note is A, so twelve notes.
A4 has a frequency of 440hz, A5 has a frequency of 880hz, and A3 has a frequency of 220hz.
When you double your frequency, you go up one octave, or up 12 notes.
A scale is a sequence of notes in an octave that gets you a specific sound.
Going C, D, E, F, G, A, then finally B before you go back to C gets you the C major scale.
There are seven notes: CDEFGAB.
The “eight” note is the same as the first, just up one octave. When I say major 5th, you go 5 notes up the Major scale.
CDEFG GGG!!!
C and G make a major 5th interval.
This is a very easy concept to understand, especially if you have a piano or piano software on your computer, I mean music theory class 101, day 1, lesson 1 in “Music Theory for dummies!”
@@Matthew_Klepadlo thank you
@@Matthew_Klepadlo Finally someone explains the scale and chord names without overcomplicating it!
Also, using octave for seven notes reminds me how Latin called a week an "octave" in Catholic contexts
Yeah because a perfect fifth is 5th note in the scale but 7 semitones away from the base note.
So, let me get this straight. If Pythagoras complains to us about equal temperment, we should just...tune him out?
Except if he's trying to drown you, in which case it's better to have situational awareness. And maybe don't go on boats with your crazy mathmagician friends!
Oh no you di'nt!

I truly love how Pythagoras is mentioned at the start as "the one who did the *_triangle thing"_*
Pythagoras was very multifaceted.
When I was growing up, there was a mom in the neighborhood who would ring a triangle dinner bell every day at 5:30 pm. I never knew who's mom it was, so I think they lived a block or two over. That triangle sound really carries!
Worth noting that all attributions of mathematical work to Pythagoras or his followers (including the Pythagorean Theorem, Pythagorean Triples, and general work with right triangles) is blatantly false. It is generally accepted that Pythagoras' obsession with Pythagorean Triples (*groan*) came from a visit to ancient Babylon where stone tablets with massive lists of them were made and kept. The ancient Babylonians already knew about the square root of 2 and had also made extensive tablets on the subject long before Pythagoras was born. Pythagoras wasn't a mathematician, they have it right in the video about worshipping numbers because he and his followers were numerologists. Pythagoras is known for work on politics and philosophy, but Mathematics wasn't actually in his wheelhouse.
I truly hate that
Who knew the "triangle thing" had such far reaching applications as predicting the Won/Lost records of baseball teams based on the number of runs scored vs runs allowed? It can be done with Pythagoras!
For the last point, some bands and orchestras actually compensate slightly to account for equal temperament being slightly "out of tune" - players are often told to "flatten" the major 3rd interval in a chord, and slightly "brighten" the 5th. It's a very subtle change for most people, but as soon as you do it, it changes from a "very good" band to an "extraordinary" band. But this usually applies to large and long chords, not necessarily every single note.
Absolutely. This is giving me flashbacks to high school, where in band but especially in smaller ensembles we were always taught to do such adjustments, especially when you were playing the fifth in a chord. Really good vocalists who sing in harmony with each other tend to do this even if they don't do so consciously or know the mechanics behind it, because it just sounds better.
Choirs too
we had a student teacher led our orchestra one of our high school years and I wondered why he told us to play our F# a little flatter in Dmajor
isn't this called Just Intonation?
I remember being in high school about 27 years ago and learning that a perfect fifth was 1.5 times the frequency of the root. I was in detention one day, so to pass the time, I started with 440 and multiplied it by 1.5 twelve times, and then divided by 2 until I got 446 (with a bunch of numbers after the decimal.) I assumed I did something wrong, and didn't realize it was a fundamental mathematical flaw until probably 20 years later, when I learned about equal temperament on Wikipedia. How I wish I had resources like this when I was a child!
What were you in detention for?! You are clearly very clever and surely must have behaved well in class?
@@AKoMMusic Thank you, and I did! I was in there for tardiness; I've never been a morning person, and when you get to school late enough times, they give you detentions, because they assume it will somehow cause you to be able to wake up earlier or something.

Tritones and Wolfe Tones weren't banned by the church. That interval was avoided, but never banned. Bach used tritones and parallel 5ths and 4ths all the time.
^^^
Hmm, there’s a note in my research from a couple of years ago for a different project that says there were some tritone/wolf bans. I don’t have access to the book it came from anymore so I’ll try and get my hands on it and get back to you. It seems plausible I misremembered or mis-paraphrased.
Two things to mention about your point though: Bach was part of the Protestant church not the Catholic, and was alive much later than the presumed time of the bans.
@@OliverLugg my understanding is that it was not common practice to use tritones since the goals in music were about glorifying God with beautiful melodies that would reflect divine harmony. Therefore, the church and musicians simply wouldn't want to use the tritone.
Also wolfe intervals weren't a problem for choirs since they can fully adjust pitch.
@Maximillian Hallett
Right, finally got my hands on the book I took that from (Big Bangs by Howard Goodall). Apologies for taking so long, I couldn't go back home for a while what with the pandemic and all.
It seems I might have paraphrased something in an unhelpful way - the important line in the book reads 'combinations of notes that derived from "impure" ratios were frowned upon by the Church' followed by another line describing the intervals as 'forbidden'. So a bit ambiguous and maybe taking some liberties with that 'forbidden' description. Having looked elsewhere, it appears actual bona fide bans may be a myth.
I'll pin a comment with your correction, thanks for pointing it out.
Why do you think God made man on the 6th day and rested on the 7th? Because that day was Loco (Locrian loki) it has no resolution and contains the tritone which is B and F the Devils interval. In western functional harmony we omit the 7th scale degree chord because it's diminished. It doesn't have a perfect 5th.

The difference between “perfect tuning” (Pythagorean) and “standard tuning” (equal temperament) was demonstrated in a documentary using the church organs of JS Bach time, each which only sounded “in tune” if it was played in one key only. The concept of tempered tuning was subsequently developed with the introduction of the piano-forte. Despite this, stringed instrument players can and do at times move their hand on the fingerboard to produce a frequency that is closer to the “perfect” sounding pitch. Hard to explain here but best demonstrated with the major 3rd and major 7th. On a violin, if you raise these pitches slightly higher, they actually sound more pleasant - especially in the case of the major 7th. In the case of the major 7th, this note is also referred to as “the leading note” because it wants to resolve your expectation of sound back up to the octave or root note and hence it's pitch sounds more pleasant closer to the root note. The Indian culture is much older than our Western culture and of course, they even have many more notes (we call them micro-tones) within their standard octaves.
There's people who actually pull in notes from other keys and make it work to masterful effect. Why didn't anyone try exploring this?
Their culture isn't older than ours. In regards to what? They don't have just one culture and neither do we. Your statement doesn't really make sense to be honest. Even the Indo Europeans migrated from the Pontic Steppe into India, which is modern day Ukraine. The oldest civilizations in the world are those of Neolithic Farmers who lived in eastern Anatolia and the fertile crescent. Who then migrated into Europe. People have been playing music for a lot longer than our current cultures. Just because their ideas are different, doesn't mean they are older.
In regards to agriculture, farming, and horse riding our culture is thousands of years older. So what you're saying just isn't true.
The original Cajun music used what is called "just intonation" (which may be the same as perfect) They used a one row diatonic accordion that covered 2+ octaves in a single key that was tuned just. The Acadians also used the violin which is almost always tuned in fifths. It turns out that the 5'th note is almost the same in just or tempered so you can play open strings on the violin and it sounds OK for Cajun (other than open strings, the violin can play any tone, so it can play them just).
So, if you want to hear just music, listen to authentic Cajun music, especially music without a guitar, although the guitar is usually only playing chords and doesn't really detract much from the just sound.
Buddy, Math describes the world… but the world is Physics, it is not as perfect as Math. The world is discrete, finite.
The Just\Pythagoren intonation (temperament) for Music does not care about physical structure of material and even Geometry… yes, it is ironic to say this about the pythagoreans.
What 1500 years after Pythagoras was done with the Equal Temperament was the compensation for the imperfection of the real physical world. Also it was about time with the invention (discovery) of the Logarithm as the mathematical method of approximation (Calculus) between sums and multiplications (powers).
Pythagoras did not break anything.
He just showed us the perfect, linear structure of Musical notes. But Music is produced by imperfect musical instruments with physical characteristics and various geometry (shapes and sizes) emitted through an imperfect medium (air) environment. Music is not static (always starting from the same tone
ote) and linear - it is dynamic and intertwined in harmonies and overlaps.
The Equal Temperament (ET), through the approximation of logarithms, gave us the best fit for the real application of Music!
On certain instruments there are structural (geometrical) tweaks we can implement, such so certain combination of notes to be as close as possible (more so than ET) to the Just intonation. We call this tweaks True Temperament.
Also, a fifth, octave and those obsolete music "theory" names were introduced 1000 after Pythagoras, with the establishment of the Church chants (most of which had 6 and 7 notes, called Church modes… somehow derivatives of the old Mediterranean\Egyptian modes of Music at least a few thousand years old).
The only one who fuскed op Music were those church monks such as Guido d'Arezzo, favouring 6 (later 7) out of 12 notes already known, assigning their favourite Latin alphabet structure (sequence) to those 6 (7) notes, and also naming them after the syllables of their favourite religious psalm, on the notes of their favourite mode (which had 6 notes, later the 7th was added) and pretentiously calling it "natural" major mode!
The mess we can see today in the form of the standard Music notation (score)!
As a musician I found this to be educational, fun and informative. Being mathematically challenged it was way over my head. Thank you. Loved it.
The “devils interval” thing is poetic, not literal.
Imagine if somebody instead called a tritone “a pain in the ass to use” and 300 years later we think of the tritone as “the interval of pain”
A future historian thinking:
hmm the interval of ass-pain? interesting, maybe it resonated with their sphincters causing this pain?
I will write this down so others may know of this!
I have a color for each note, and i noticed that the tritone of each color is the opposte color. For example, C is red (love songs are always in C). But the opposite color of red is green, which to me is the the tritone, F#.) It also makes sense because F and F# where the Pastorals keys in Classical and Romantic music.

I’m devastated by the fact they banned BEANS!
As a musician who's never been good at maths, this was so validating to watch. Equal temperament / focusing on interval tuning just comes naturally to me, whereas I'm always mystified by people claiming to have "perfect pitch". Hope you got a good grade on your project because this is good stuff!
Equal temperament just shows us another reason why perfect pitch, although real nice and impressive, isn't needed to be a great musician. It's all about the relativity of the intervals and being able to hear/identify those contextually.
What's weird is I've never understood how music works even though I play guitar until you explained it to me mathematically
Fun fact, despite the fact that some brass instruments naturally play perfect intervals because of the way they work, we often shift the note slightly to make it fit in equal temperament, because it sounds nicer. So that's the other reason you don't normally notice it.
Curved brass instruments don't necessarily default to real harmonic intervals anyway. The real world of acoustics is necessarily a lot sloppier than P man seemed to think. Consider real spectra of any 2 hammers hitting any 2 anvils and P man is already off to a bad start.

CORRECTION: It's been brought to my attention that the Catholic Church didn't really 'ban' complex ratios so much as frown upon them. It looks like the existence of such bans may be a myth.
It's also pretty important to note that all modern Western music theory has it's roots in counterpoint, which was the system the Church came up with to write holy music, so any bans in intervals were bans of using those intervals in music meant to be played in the Church. The Church didn't really care that much about music that was played somewhere else than the Church.
They did ban the tritone though, as the so called "devils-intervall". ;)
@@nobodywilleverknow8371 No they didn't, that is complete revisionist history perpetuated by edgy metal bands. It was rarely used because it's hard to sing, not due to some association with the devil (in fact it was only called the devil's interval several centuries later for that exact reason).

This is a sine wave. *TH-cam compression proceeds to completely unravel the video at its seams*
I think the TH-cam algorithm must have regressed slightly. There are loads of artefacts on graphics that should be simple that I can’t remember was a problem in the past. I guess developing compression algorithms, you fix something, break something else.
@@roygalaasen probably they have new algorithms that save more space in spite of quality of these kind of scenarios
@@roygalaasen TH-cam is absolutely huge - they've got an *extremely* strong compression to hold all the tens of thousands of hours of video they receive every single day. The quality loss isn't a "bug", it's just because they're compressing it _so_ _much_ - but have to given the sheer amount of data they have to store.
@@Alex-ABPerson you are right, of course. I never claimed it was a bug. What I tried to put in words was that is is hard to balance an encoding compression algorithm to perfectly manage every single situation to an 100% degree. You fix one situation where the algorithm goes wrong, you may create another where it does not work as well any more. It is in the name “lossy compression”.
This is a balancing act on how much quality you are able to squeeze out for as much loss of quality as possible.
But: when it ends up hurting most of the videos you are watching, maybe you should find other ways to optimise storage. For instance, there are probably loads of videos that are just stored in the system that nobody even knows of or remembers. Maybe move those over to an offline system and bring it back online if ever anyone were to request it again.
@@roygalaasen That doesn't really solve the problem that they still have to store _tons_ of data, though. It requires less energy... Maybe... But with even then *how* *many* people are using TH-cam they'd be *constantly* "turning on" these "offline systems" all the time just to pull data off them because people literally all the time all over the world would be requesting stuff back again.
Plus it really sucks if somebody uploaded something rare 10 years ago and they were never seen again after that, and their video went offline and neither they, nor anyone who really paid attention to the video, requested it back... It would just become near inaccessible for forever. Just in general it would be really frustrating - and all of that just to improve video quality.
And it's not like it's the end of the world YT heavily compresses videos - because if you were say, a broadcasting company and _need_ high-quality streaming, you can just use other (or even your own) services that don't compress anywhere near as hard. And for educational videos like this, it generally really doesn't matter.
I'm a music education student, and for the most part this is true, but your notion of "people not hearing any instrument play anything other than equal temperament" is false. Although for some instruments, this absolutely true, namely pitched percussion, and Piano/keyboard. However, most instruments in an orchestra or concert band can move pitches around a bit to deal with all the fudging. Any professional musician worth their salt generally will make the chords more in tune with the actual ratios by ear, slotting in closer than the 12TET allows for. Some instruments, namely brass, physically can't be made in the 12TET tuning, as the pitches played on trumpet deal with the harmonic ratio, I.E. 2/1, 3/2, 5/4 etc. (That pattern does get messy up higher in partials) When I play Trumpet (my principle instrument), I am keenly aware of this, and have to alter my pitches to compensate for this to get the overall chord in tune, with some pitches having to use slides to physically get rid of the really dissonant intervals that come about, such as the Wolf's Fifth.
Overall, still love the video! Great job.
Omg I've never thought about how that would effect brass instruments, I was wondering why trumpets have a tuning slide.
I genuinely did not know that brass couldn't play in 12TET, so thanks for that information. I'm aware of that point about non-fixed pitch instruments playing other tunings at will though.
Can confirm as a trombonist, dunno how you guys lip bend it to be in tune, since we can always adjust the slide on our end. I believe the principle also applies to fretless strings because of how the harmonics of strings work.
And not even pianos are generally tuned strictly to 12tet. They sometimes are, but the octaves are often stretched because the high tension on the piano strings stretches their harmonic series, actually making the fifth closer to JI and the major third fursther away still.
Presumable you mean that brass instruments can't be tuned to play multiple 12TET notes *simultaneously*. Like a single string cannot be tuned to play two such notes simultaneously, since they are not harmonics.
But separate strings, or separate tones on a brass instrument, can in principle be in such ratios, surely.
Awesome video, visuals and numbers really help me learn and I've been struggling to wrap my head around these music concepts x.x
I've been wishing for a comprehensive video like this for a while lol
Many years ago, I watched a professional piano tuner at work and it was fascinating. I was surprised that he wasn't just simply tuning each note separately using some digital tone creator (I had a Pythagorean understanding of music without knowing it). He answered my questions by saying that it was important to tune the piano "to itself" based on octaves. I never understood what he was doing until now. Thank you!
This is actually why a really good orchestra is able to tune to themselves. Skilled musicians can hear the perfect intervals (overtones) and mildly change tuning from equal temperament.
Exactly. Bowed, non-fretted string instruments and singers are particularly well-suited to the fine gradations of perfect tuning.
@@jimslancio and in a choir, the third of the chord will NEVER be high enough!
They tune to fifths, starting with an a of 440 hz and tuning the lower d to it then g, then for cellos and violas c then violins and bass tune the a to a higher e
Me only playing the piano: ლ(¯ロ¯"ლ)
Yeah, I always tune my strings in fifths when alone. The resonance makes the sound better (or at least louder).
The fact that music can be explained through math is amazing.
Only the structural aspect of music can be explained through math tho. Its emotional and spiritual aspect will forever remain a mystery, probably.

I am a painter and my brother is a musician. The similarities between the disconnect in instrument tuning and what we encounter in colour theory is striking, and I feel like I might understand him a little better now.
The space itself is consciousness. Movement. Geometry of light. Temperature, color, sound, emotions, thoughts...all the same geometry, all the same system. Movement is a scalar structure of light and therefore all phenomena you percieve is the same geometry of the same movement only percieved under different angles (phase shifts and polarities). The geometry of physical mind itself is the geometry of all things created in the physical mind...
@@tomaskoptik2021 sounding like a Pythagorean lol
@@pastass8857 Pythagorean school is not dead :)))
@@tomaskoptik2021 That's making something falsely profound of something trivial. It's not that space itself is consciousness, but rather that the brain is the common denominator and all types of perception is filtering of patterns via the senses. This translates to information patterns in the brain that are easier for the brain to process while less easy to process patterns feel discordant.
Just like how both music and painting can follow the principles of design; Repetition, contrast, variety, and so on.
Only repetition is boring, only variety is chaotic, contrast tells of the intent of the piece, etc.

Awesome video, well produced and love the humor. Would love to see a video on the history and usage of the pentatonic scale someday!
Such a great video! A concise yet rather detailed essay on the history of tuning!
Thank you, Oliver!
When I was young, I was introduced to the practice of tuning a guitar using harmonics. I thought this was a great idea, since harmonics are relatively easy to get more or less perfect - by listening to the "beats" they produce. So I had this idea that, if I was careful enough, I could get my guitar pretty much perfectly in tune. However, in practice I never could. Some chords sounded downright awful - and I couldn't understand why, given the precision which the harmonics afforded my tuning process. Imagine my surprise many years later when I, by way of a youtube video, was informed that this practice actually makes a guitar precisely OUT of tune - for the reasons that you've explained here. Good to know. Thanks for your work. I appreciate videos like yours that carefully explain interesting and useful information to us - the masses.
Oh hey! That isn't why its out of tune with certain chords. It's the intonation of your guitar that isn't correct. Which is unfortunately caused due to the saddle not being set for the gauge and tension of the strings. There is a lot of systems to sort of rectify this, (fanned fret, Buzz Feitan, true temperament frets, etc) but a harmonic is a close to a pure fundamental note you're going to get on a guitar, and shows you the pitch exactly as it pertains to the tension of the string and the force you struck it with. Listening to the beats is how a piano tuner tunes a piano and it is a good system, but due to most guitars having bad intonation, I can see how that would make someone assume that tuning and listening to the beats makes a guitar out of tune. The guitar is in tune to it's open strings that way when tuning to the beats, but the intonation of the frets is not correct when the saddle is not set for intonation. So it's the bridge, not you or tuning to the harmonics. Just wanted to clarify!
@@DonnyBurbage Assume that you tune the A string via harmonics to a fifth above the open E string note. Assume that you do it in such a way that there is zero beat frequency, or in other words, in such a way that you get *exactly* the same frequency. Then you have in fact tuned these two strings in (perfect) Pythagorean tuning, right? Now, when you play an A note on the E string (5th fret on the E string), then the note you get is *not* a perfect fifth above the open E string note, but instead it's a fifth in 12TET. So, when you then play the open A string at the same time, then you have two *different* A notes sounding at the same time, in harsh dissonance with each other. I think this is what Fred Hughes tried to point out, and what had been shown in that video (which I haven't seen).
The consequence would be to *not* tune guitar strings via harmonics to perfect fifths, but instead to embrace the fact that a standard guitar is a 12TET instrument. For example, tune the A string by playing the open A string together with pressing down the E string in 5th fret, and by eliminating any beat frequency, until zero beat frequency is reached.
The problem with this tuning method is that you're tuning the open intervals to perfect intervals, but your frets are placed for equal temperament.
I remember simply memorizing the default tunes of each string, and then trying to replicate them as closely as I could by tuning them by ear. That gave me the desired results 99% of the time.
@@storerestore yes, the opens strings are in tune with each other as open strings. And the guitar frets are equal temperament, but that’s why the saddles are not perfectly lined up. They are adjusted to compensate for the frets not being in tune. The only problem you will find is that the 1st fret and 2nd fret are sharp depending on the string gauge. But the Buzz Feitan tuning system adjusts the saddle to be closer to the first fret to address this. Other systems exist also to address this same problem like I mentioned. But tuning by beats is how a piano tuner tunes a piano.
I also just want to point out that in-tune is kind of the wrong word to use honestly, due to several other cultures that have different tuning systems that are deemed pleasant to them. Balinese Gamelan would be a good style to check out as they use the warbling beats that are perceived on purpose to mimic the shimmering waters of their country.
I have known about this for years (it is usually formulated as "it is impossible to tune a piano"), but this video has finally made me understand it. Thank you!
But you can tuna fish

@@granteubanks People dont recommend each other enough
Science-TH-camrs.
I try to change that. Anyone has and/or wants a Recommendation?
This beyond temperament. A string has inharmonicity, it is out of tune with it self. The harmonics are not "harmonic" to it's fundamental. This is why we stretch tune.
This was a great video. It not only communicated the point, but made me appreciate music on a level I'd never even considered before.
In many contexts I still hear mean tone and Pythagorean tuning as more pleasing that equal temperament.
That said, this is just about the best explanation of the maths that I've seen in 40+ years!
Thanks for making this video.
A few years ago I started wondering at why ALL pianos sounded out of tune. Every recording across time, if it's just a piano, it sounds slightly janky to me. This started a rabbit hole journey into musical theory. This video greatly simplifies that journey, and I'm happy it now exists.
You are probably one of pythagoeas’s descendants
@@nrcarl00 or just not tone deaf.
There are also tuning systems that put the compromise elsewhere. Each key has a temperament that suits it more. Equal temperament only has the octave that's in tune.
Pianos use "stretched tuning", where the lowest notes are tuned slightly flat and the highest notes are tuned slightly sharp. This is done to compensate for some imperfections in the harmonic relationships of the physical strings.
Do you have perfect pitch? I wonder if those who do have perfect pitch get irritated by the slight out-of-tunedness caused by equal temperament.
@@kennethgarland4712 Rick Beato questioned his son Dylan (who has perfect pitch) about this a few years back. He said that the notes didn't bother him or detract from the music in any way.

Nice! Very well done!
I stumbled upon this equal temperament when looking for an exponential function model (I'm a Math teacher) to have students manipulate and explore. Without too much musical history knowledge, I started with frequency doubling between two notes an octave apart and the assumption that half-tones were evenly spaced on that exponential (logarithmic) scale. I later heard of these ratios and quickly realized that there would be discrepancies between the two models. Now I know the contexts. Thanks for bridging this gap with this insight!
That was very educating AND entertaining. And now I must dig out my old books on tunings and reprogram my VSTs to sound weird.
Great video!
Fun fact: he did not live in ancient Greece, he was born there in Samos, but he lived most of his life, and also founded his school, in Kroton, a city in Magna Graecia, which was basically a group of Greek colonies that became independent in the south of Italy; Kroton's region specifically is Calabria , and the city is called Crotone today.
I know it is basically pointless to correct this, but it is the city I live in we are talking about, so I felt compelled to do this, since we are very proud to be the city where he lived and had his school
Also, if it may interest you: he didn't ban beans, but faves specifically, and the reason was that he was allergic to them (it is said that he died by wandering into a fave field while being chased by an angry mob). This rule was not for his "followers" as much as for the students who attended his school, who were forced to accept everything the teacher said as truth, without being able to contest it ("Ipse Dixit": "He said it") for their first 5 years of studies: after this, they were allowed to sit next to him and intervene during lessons with their opinions. This was a precursor of modern high schools.
Other weird rules include the fact that you were for some reason not allowed to break bread using your hands (never quite understood that one)
As long as we're splitting hairs...
To the ancients, anywhere colonized by Greeks was deemed to be Hellas (Greece).
@@mikecrowley2472 I guess it is fair, but it is also true that Magna Graecia was recognized as some sort of independent region after a while
It is of course still "Graecia", but was considered as its own entity
Ancient Greece was really just the entire region where there were Greek collonies, or city states. They didn't have to collaborate with eachother to be part of this sphere. Some of them were under foreign rule. I am Romanian, so an example from my region would be the Greek colony of Tomis, which was under Dacian rule, Dacia being a Kingdom/Empire contemporary to the one of the Romans. They were conquered and recognized the sovereignity of Great King Burebista, yet they were still part of the Greek world.

Excellent video. This was the most thorough, yet easy to understand video on the math behind intervals that I have seen.
They couldn't eat the "Broad Bean", not just any kind of bean.
There are better stories about their broad bean ban though.
Once Pthagoras went for a walk on a field, and there was a bull standing on that field. It was eating broad bean. Pythagoras came close to that bull, and whispered something into it's ear. Ever since that day that bull never ate bean again.
The pythagoreans were raided by the Athens police. They tried to run, but the only wa they could escape was through a broad bean field. All died...but one.
When he stood trial, he was asked by the jury:
- Why didn't your brethren run through that field of broad beans?
- They'd rather died than stepped on broad bean, and I'd rather die than tell you why
You would have to be a Pythagorean to know (or the bull)
Great explanation of tempered music. It also follows why untempered instruments sound better in certain keys when played 'naturally' (ie as per Pythagorean)
And why transposing on a tempered instrument can make trouble!

Beautifully explained, with just the right dose of lightheartedness to retain interest in a pretty complex subject.
This was lovely. It had a nice steady progression of the maths and narrative. Thank you!
There's more than just 12 tone equal temperament and Pythagorean, lots of cultures have their own tunings, and you can also do equal temperament with any number of notes per octave (if you're interested in hearing that, Sevish produces music in a whole bunch of different tunnings)
Yes finally another person knowledgable in music's in here
This is a video about European music, sir
@@xxgimpl0rdxx22 if you want to be like that, Bach used well temperament and quarter comma meantone was used more than equal temperament in the 1500s (which is also a meantone temperament). There's also third comma meantone which is roughly equivalent to 19edo (equal temperament but with 19 notes per octave)
Microtonal music ins't better though and the arguement behind it is a reoccurring epic fail. If it made sense someone would have used it to produce music *successfully* - (key word) by now. The reason why it doesn't work is, because our brains can only percieve 12 distinctly different pitches while all other possible imperfect inbetween notes voice sympathetically to it's nearest more perfectly harmonically related neighbor from the perspective of a fundamental frequency... In other words, microtones always just sound like slightly higher or lower detuned versions the standard 12 tones and the music created is always ugly, unstable, and just gets weird potentially even annoying, everytime. There is no "better" major scale that can be obtained with microtones and instead it only furthers musical deviation from it. Sure you could use microtones sparringly and get some slightly different character out of them, but completely cutting things up totally differently just doesn't work musically and always lacks cohenrence and rythmic pulse.
@@dickrichard626 how does the tone effect the rhythm? also there are other non-western cultures which use "microtones" in their cultural music (as in they have their own tuning system separate from western system). Its nothing about our brains being hardwired for 12 tones, its just the cultural norm and that has an impact on what people are expecting to hear. If you took a newborn and only played them microtonal music, then I would hazard a guess that they would find 12-tone odd sounding (to my knowledge no-one has done this, although as mentioned before other cultures have their own tunings that don't sound odd to them.
If you want to talk about successfully using microtones in western music, Grammy winner Jacob Collier uses them quite often, most notably when he modulates to G half sharp towards the end of his version of "In The Bleak Midwinter".

Excellent video. Very informative. I was highly impressed with the editing. It kept my attention and I learned a lot about how we, culturally, have been conditioned to hear these irrational tones as normal scales. I had heard about the church banning that specific note combination, but have heard it used in some modern chiptune experinments by people and was curious what the deal was there. Now I know that was using a pythagorean scale which makes a lot more sense. Thanks for helping me to better undestand this. What's especially funny is I've been playing jazz for decades now as a saxophonist and had no clue about aaaany of this irrational number stuff ha ha.

I've been watching videos about music theory. This is the best one so far! Well, done, Sir!
Pythagoras did not "invent" anything musically. He just put numbers to it, and did some theorizing about how music "should" be. There is archeological evidence that the Babylonians -- and possibly before them, the Sumerians -- used a 7-tone Pythagorean (ugh) scale. And based on what we know about ancient Greek music, a hypothetical 12-tone Pythagorean system had virtually nothing to do with musical practice. The Greeks thought in terms of tetrachords (the interval of a 4:3 divided into 3 parts), which could be stacked to form larger scales. Some tetrachords qualify as Pythagorean, like 1:1 9:8 81:64 4:3. Others do not. Some sources (particularly Aristoxenus) describe dividing 4:3 into some number of equal parts. Some (Archytas and I believe also Ptolemy) describe non-Pythagorean just tetrachords like 1:1 9:8 5:4 4:3 or 1:1 28:27 16:15 4:3. The point here is that the Pythagorean wolf fifth (more on that in a moment) did not factor into ancient Greek musical practice because musicians were not modulating around a closed 12-tone system, nor were they employing harmony (at least not in the sense of European polyphonic music). So the failure of 12 x 3:2 =/= 2:1 was a purely philosophical problem, not a practical one.
When it comes to the late middle ages / early renaissance in Europe, the Pythagorean wolf fifth was also not really an issue. For one, while there was some concept of a 12-tone system, composers were typically not writing the kinds of the modulations that would run into a bad fifth. Second, the dominant musical format (at least in liturgical settings) was a capella vocal polyphony; vocal music is never strictly Pythagorean, and singers would certainly correct a bad fifth via adaptive intonation.
There seems to be some confusion here about wolf fifths vs tritones. In a strictly Pythagorean system, the wolf fifth is a bit flat of 3:2 (in decimal format, roughly 1.48), but not quite as flat as a true tritone (9:8 x 9:8 x 9:8 = ~1.42). It was the tritone that was discouraged in liturgical music (as others have pointed out, it was never "banned"), not the wolf fifth. It may seem like a minor distinction, but they really are two different intervals. The wolf fifth was a discrepancy of tuning that could be adjusted for in practice, while the tritone appears naturally in the diatonic scale (whether the intonation is Pythagorean, meantone, equal, or something else) and can only be resolved by adding an accidental.
The other issue is that the concept of a wolf fifth only becomes truly relevant in the meantone era, when a sense of triadic harmony developed (1/4-comma meantone produces a perfect 5:4 and a good 6:5) and composers were employing more distant modulations. In meantone, the wolf fifth is *wider* than a perfect 3:2. This interval would typically be placed between G# and Eb, or alternately C# and Ab. And that's usually what people mean when they use the term "wolf fifth" -- a wide 3:2 rather than a narrow one. The transition from meantone to well temperament to equal temperament was a progressive attempt to minimize that wide wolf fifth. So ultimately, the practical concern over wolf fifths stems from the shortcomings of meantone, not Pythagorean intonation.
Somewhat ironically, equal temperament is mathematically closer to Pythagorean intonation than meantone. Yes, that has to do with the development of the pianoforte (whose timbre is much more forgiving of intonational errors than the harpsichord), but also the symphony orchestra, which brought together many different instruments, each with their own timbre and intonational tendencies. Equal temperament is the "middle ground" that enables all those instruments to play together more or less harmoniously.
So...It's an interesting video, and all the math is correct. But I think it presents a somewhat misleading narrative of why Western musical developed in the way that it did.
Thanks for the clarifications. I've addressed the main points in the new pinned comment.

@@clementbenny Just remember that color is light and an electromagnetic sine wave.
While music is sound and a longitudinal sound wave.
But the frequency is more or less the same.
Yes, he represents 12-note scale as the “correct” one (despite it just being one of many possible approximations), and natural harmonic intervals as “broken” which is ridiculous.
The wolf interval sounds like the sound you make when your trying to tune your instrument but your not quite there.
when "not quite" sounds = nearly half an octavre

for some reason it sounds normal to me

Splendid presentation! Far more concise and relatable than the boring classes I took in college on this topic!
I found this fascinating - I was a Barbershop singer, and we spent a lot of time FINE-TUNING chords, to make them ring. The first thing we realised was that the note that a keyboard plays is not EXACTLY the same not as the harmony voices need to sing to make a chord ring - it was obvious that the differences were small, but REAL. I knew the mathematics of harmony, overtones etc, but your video consolidates my basic understanding. Thank you.
Great video. Probably a little late for the survey, but I also wish you would've included Just Intonation, as that was by and large the accepted system before Pythagorean. It also sounds really good when restricted to its key center
I might need to re-read that defn in the video, what were the Egyptians using (if known). It came to my thought that the pythagoras as a philosopher took the (rational) mathematics as a 'dogmatic religion' rather than investigating and noting the wider interestingness of irrationality (in base 10 land) of root 2 and other irrational numbers / golden ratio in nature as being (perhaps) the difference between 'knowledge - forbidden in the Genesis 2 bible story' and the intution of just sitting back and enjoying that which has been created (and dont get me started on electrons and sub particles as a function of creation !!)
Wow, this is the most interesting thing I have seen today! Congratulations!

I loved this. It tied right in to the music theory I’ve been learning. In fact, I told the person watching with me something like “watch - the problem is going to be that Pythagoras based his scale on fifths…” and you said exactly that, 30 seconds later. Made me sound like a genius. 😇
This was incredibly informative, not even my Berklee class could explain this as well as you did. Thank you!
I found this fascinating. Not being particularly strong in math, I was pleased that I was able to follow the math as you explained it. Very well done.
I enjoyed this video and learning these basics. I'm not a music student although I learned to play the violin (almost) and the piano (moderately), nor am I a math student so the math was just barely within my grasp - but enough to understand the concepts.
