For non-musicians who might stumble upon this video and be confused, Jacob Collier here is essentially explaining the *INTENTIONAL* tuning discrepancies of a piano called "equal temperament" as opposed to "just intonation". Mathematically, it is only actually possible to tune to one musical "key" at a time (ex. A major). This is a problem for many reasons, but one of the main ones is that it takes a very long time to tune a piano. If you were to play one song in A major, then the next song you're meant to play is in C major, you would either have to spend hours re-tuning your piano, or roll out a completely new piano. This is, of course, completely impractical, so a system was designed where every note is very slightly "equally out of tune" with each other. Collier is saying that he instead wanted to approach must with "just intonation", which refers to tuning based off of "simple" ratios between notes (simple is relative... it gets complicated quickly). This is generally considered a bit more easy on the ear, and is a more traditional method of tuning. This is obviously an overly simplified explanation, and entire encyclopedias have been written on the principles of tuning instruments, but I hope it helps someone understand a bit more.
I think Paul Davids video on John Frusciante explains this problem very well. For people that want to learn more about it you should check it out, the video is laid out so even people without a lot of music theory knowledge can understand it :).
@@OzzieWozzieOriginal The cop-out answer is... it depends on the tuner! Most tuners I see are tuned equal temperament around A440 just like a piano, but some guitar tuners (especially cheap ones made by engineers who understand math but not music) are just intonation. Generally the tuner should tell you somewhere on it what temperament it uses (for example "A440/A432 calibration" would mean equal temperament), but higher quality tuners often have methods of switching between tuning methods. So TL;DR: yeah they're usually also out of tune ;) but sometimes with the option to fix that!
@@moomoocowsly Watch enough of his stuff closely enough and you'll see he really does have perfect pitch. The Moon River "making of" vid is an example. It's not a miracle. Rick Beato's son Dylan could identify all kinds of chords aged I think about six, there's at least one video of them doing it.
@@moomoocowsly I’m sure there’s some of that, he does come off with a bit of an ego but he also does have a pretty insane level of perfect pitch tbh, it’s not like it’s unheard of though
Does this mean that you could program a keyboard to play in just intonation? The keyboard would just tune itself to whatever key you’re playing in? (Of course you couldn’t modulate or play chromatically.)
@@johnlanou yes, most DAWs should allow the tuning to work like that, you could also build one using MAX/MSP or PureData (the freesource analog), there is always the digital audio dilemma regarding harmonics but most of the classic synths sounds we know today were built using different tuning systems !
@@lol-zp1ps other instruments are so easy to tune, it wouldn't be much of a problem. Most wind instruments are fine tuned multiple times through a performance (slight adjustments to mouthpiece and reed position are never ending realities of orchestral life. Guitars and nearly all strings are easy to tune. In fact I'd bet "concert tuning" with no piano present would probably be closer to key specific just intonation...
@@lol-zp1ps you are correct. I have the jargon all mixed up, it's been a while. I just mean, so much of the playing I did was sans piano, probably it made us do less equalizing while we refined our intonation.
@@troysmithfr If you knew for real you would know that there's no solution. If you had to play all the intervals of a melody with perfect ratios and then return to the root you would find that the root you ended on is not the same note you started from
@@Davide_LP That’s for instruments with a fixed set of notes. Anything with an arbitrary amount of precision could be written for in just intonation with no problem. Jacob has talked about retuning guitars in between takes, so the DAW essentially allows him to do this with fretted instruments as well. Most music doesn’t even involve key changes at this point and the home tone drifting by commas doesn’t bother me. Everything else is a matter of tooling and shared language, which are both getting better
@@Davide_LP Exactly this. Equal temperament is the best we've got to be able to play in all keys using a 12 tone system, so instruments basically have to use it. Imo, It's just something that we've gotta live with since 99% people don't even know it's out of tune. For people who do know about it, it's something we should work around. Drop in a little just intonation and maybe even totally different tuning systems here and there, similar to what Jacob does. Too much spice ruins the dish.
@Martin Baldwin-Edwards indeed.. I am German and our grammar is a little more complex then (than? Never get that right) English grammar is. When I form a complex sentence with a rarely used case, autocorrect tries to tell me it is wrong, even though it's perfectly right. Sometimes autocorrect doesn't even know a case modified word exists. And this has consequences on people's speech patterns, and writing styles. Germans now, speak and write way simpler than Germans 50 years ago. It's some weird degeneration of speech.
@@lloydaran I believe it's irony. The way I read it, he's saying "computers think they know better than me," but what is 'in tune' to a computer may be in fact out of tune using a different tuning system, like just intonation.
@Martin Baldwin-Edwards I'd like to offer a counter argument. Usually computer programmers don't put basic knowledge into their work. Programmers do just that, -they program. All the knowledge conveyed by their final work is provided by trained professionals in that field. Programmers who make software for MRI machines don't fill it with mediocre medical knowledge. While I for one keep autocorrect disabled as much as possible, I know for fact that it has been made with the help of linguists and people who are knowledgeable on the subject. There's a lot to say about this, but I believe it's important to remember that portraying emotion and expressing one's self are both matters inherently subjective and no amount of even expert knowledge will ever be able to fully represent everyone.
The human ear is pretty darn remarkable and Jacob got a pretty good pair. 30 years of tuning pianos for a living and only had one customer who could actually tell me when the partials were right for A4 without a reference point and be accurate within 2c- cents. Absolute pitch. She considered it a curse.
I'd consider it a curse. If you're focusing that hard on micropitch differences a normal human can't even discern well... you're kind of missing the point of music lol.
It is amazing, especially to someone who haven't heard the difference between pure and equal tempered thirds before. That said, a lot of people, even people reading this, could do the same demonstration Jacob does in this short video clip. Which is of course not to claim that we can do all of the amazing things that Jacob can do with his voice.
You can ONLY do it with your voice. No surprise there. He's going to become an Engineer next and wonder why nothing is ergonomically correct. From him, I would expect less than 1% off and then try to hear it. I'm well-aware that I'm way off by a dB let alone a pitch that should shut down music.
@@pierrelacazotte8376 You're making very little sense. I was referring to the fact that you would have a much easier time demonstrating this with a synth tuned perfectly, rather than a human voice which is not mathematically correct and works solely by instinct.
@@MiloMcCarthyMusic You're making little sense, but then again - you don't speak more than one language...english isn't that colorful which surprises me because if you're from Enland you speak what? English. If you're from the U.S., you speak American. Voice are tones, language world music -- if you want to, you can do that. Everyone would have to sing that way if you had to communicate that way - you learned it starting a long time ago.
"The human voice can be mathmatically correct NEVER only instinct" - Victor Wooten. He's right, I don't understand why people tell me that they can't understand jazz music in general because it's "too technical" Really? -- It's all about want you want to pursue.
@@dieterjones7402 Yeah I'm not sure if the comment is a fundamental misunderstanding of the joke format, or if this is just a pseudo-joke where he wrote his otherwise bland comment in the mode of a popular joke format so people would recognize it and give it likes.
Your mind could comprehend it if you studied tuning systems. Without that, yes, you likely won't figure it out on your own. Hundreds of years of musicians before you that you shouldn't disregard.
You can hear a slight wobble in the sound when he sings with the piano, this is what happens when you play two notes slightly out tune from one another. This guy is legit an alien.
By the way this is one of the reasons vibrato got into classical singing. They felt there is a gap and wanted to bridge it. And it's more forgiving, you can hide your intonation a little :) and listeners like it too, even as listeners we might feel it. Singers will sooner or later feel the mathematical relations.
@Martin Baldwin-Edwards I've noticed this too!! For some singers their vibratos are out of tune and don't match the accompanying music. I only recently learned I'm quite sensitive to microtones & intonation and I'm slowly teaching myself the technicalities of why my ears pick up that weird dissonance. Your comment helped me figure out another puzzle piece. One opera singer i respect because she has a strong vibrato that 90% of the time sounds correct and nice, is Sarah Brightman. There's a reason she's one of the greats. I think she can tell where to tune her voice up or down so the midpoint of her vibrato sits nicely on the music.
Actually each piano key produces a variety of different tones and notes, which are unique for each Piano. What happens is that your ear just picks up the dominant tone.
"How does no one know this stuff?" Actually, I feel like that is widely known! ...at least for vocalists and (fretless) stringed instruments etc. If we rehears in our vocal ensemble we never sing after the piano, especially not for those dirty equal temperament thirds. :P
I think he is speaking to those of us who make modal music using discrete, predetermined intervals… keys, frets, buttons etc. Especially people using grid based DAWs and sequencers. Most modern music tends to fall into this category. I like it, but things like Terry Riley’s Shri Camel are among my favorites. Most people are also self taught, as the last 25 years has seen many primary schools cut their arts educational programming. This just leads to a less informed, more rigid population, especially as most products are designed and geared towards creating 16 bar sequences in standard time with a consistent clock. I am not saying that is bad, though… It just leads to a predictable and repetitive track, and truth be told, dancing to trance music into the wee hours of the morning is a pretty satisfying experience, in a way that not many other genres can lay claim to… The best part about it is, now we all know because dude is on a mission to unlock music from the bonds of our programmatic musical overlords…
The irony is that Vincenzo Gallilei (father of the mathematician/astronomer) described it 500+ years ago and here Collier is trying to explain it at, checks notes, shakes head, MIT.
Here he is explaining something called equal temperament. Western music uses 12 notes of equal distance apart. But with having each not equal in distance, each note is just slightly off. So in short, he sang the perfect third against the pianos third that is slightly out of tune. If he were to tune it then playing in other keys would very off, but he can use the perfect harmony when singing because the tuned notes will not clash with other notes.
Choirs as well. They sing in just intonation, perfectly in tune for the key they are in, which can lead to some interesting effects, such as ending several cents higher or lower than they began, all simply because of the natural tendency to tune each chord justly. Across many chord changes, this can force the tonal center away from the original. Ironically, the only way to combat going out of tune is to sing [slightly] out of tune, on purpose.
@@obiwanda in my choir we literally practice singing various notes in the scale "sharp" or "flat" to actually formalise this. It is a matter of opinion what method of tuning sounds "better" or "worse", so obviously not everyone needs to do it, but it's still going to sound fine if you do sing "out of tune".
@@obiwanda Also interesting, choirs who don't use A440 tend to stay closer to in-tune than those who don't. It seems that there's something more natural about A434-436 that makes it easier to hold. Also, alot of those old cathedrals you find in europe were built to have natural resonance in them when singing, and some of them don't work as-designed at A440
It’s really simple, folks. Bach popularized the “well-tempered klavier” with his book of the same name which exploits the equal temperament by enabling us to play in every key. Moreover, in each key he travels to as far distant keys as aesthetically possible and back without any of them sounding bad. This means that when you play chamber music with piano or any other instrument which cannot adjust its pitch, you play in equal temperament. That is, you adjust to the piano. When you go back to playing with other instruments like your own which adjust easily in real time (strings, woodwinds, brass, voice, mainly) you can play “perfect” intonations, but you’ll be adjusting constantly, which is what we do. It requires practicing your pitch in various ways, but is quite doable for any good musician. It’s not rocket science. Actually, it’s acoustic science. But we just use our ears and learn how to make it work. It’s easy once you grasp it.
Its not about playing in every key, its about playing in every octave possible while still avoiding dissonance in melodic intervals. Im not sure if it was pythagorus, but a greek philosipher made an instrument using true equal temperement to try to prove that the universe held itself together mathematically and failed miraculously when he came across multiple intervals that would sound horrible together (the wolf interval i believe its called).
@@lbb2rfarangkiinok HI think Helton means the little dissonant resulting sounds when two very close but not equal frequencies are joined. I suppose that it's called "the beat" in some specific lingo.
That's so interesting ... I always thought that some notes sound out of tune in piano chords to my ear ... I thought I was crazy, but that makes sense now!
Jazz is not possible without equal temperament. Going beyond equal temperament is not bad. Musicians have been trying all the time. There is no need to shit on our roots, but grow beyond. "O Freunde, nicht diese Töne! Sondern laßt uns angenehmere anstimmen und freudenvollere. ". That's the attitude.
hes not shitting on anything, clearly hes been asked a question about his singing and he shared his story about learning of equal temperament vs just intonation
@@ghujdvbts If you're very good, you feel the differences, I don't. it's like singing. But mostly you stick to the other instrument's tunings. You will notice that string players very often use vibrato to bridge the gap and also to cover up initial minute pitch glitches.
Nope. There's a group of people obsessed with purity, sometimes it's political, sometimes it's how to tune a FUCKING piano... but in whatever way it manifests those people can't just enjoy life, shit's always got to be a problem. A problem no one but them can even detect. The closest I can even get to this level of scrutiny is probably 60hz strobing from LEDs and fluorescent lights... it's mildly annoying. If I had that level of give a shit about every little thing in life I probably would've ended myself by now lol.
That's the cool thing with classical guitars: we can intonate by fretting a note and then push it down or up. Use it all the time at key points in the music (e.g. closing chord).
You can't bend a note down tho lol and the major third is sharp. Often people tune their G string slightly flat, so they can play the major thirds on there justly intimated and then just bend the G string "sharp" when playing other notes on it like a perfect fifth in relation to something below it
@@joshuagavaghan224 the only way to do it is bend the neck in, but that will bend every note flat if you’re playing a chord. Not to mention it’s not a quick easy motion like bending a string.
@Ryandal Gilmore applying force perpendicular to the neck can indeed only stretch the string. However you can apply a force parallel to the neck, towards the body to loosen the side of the string that produces sound and consequently lowering the pitch, or on the contrary towards the head, pulling and stretching the side of the string that produces sound, which will result in a higher pitched sound (but might as well push perpendicularly to the neck for a higher pitch).
"You guys know this because Pythagoras figured it out" I hate it when people say stuff like this. Just because you understand a concept doesn't mean you can automatically apply it to every single application immediately.
I also figured out equal temperament as a teenager, and it was exactly those two notes - G and B just below middle C, that made me understand it. Before digital tuners, tuning up a guitar by ear was pretty challenging, especially to get the G and B just out enough to make the rest sort of play in tune-ish...
I experienced this during a choir rehearsal: the conductor asked the piano player to play C and G (in equal temperament fifths are narrowed by 2 cents, so it's pretty much in tune) and asked altos to sing E. They sang it and tuned it and then the pianist played the tempered third. Same result :)
I saw this video 2 years ago and it made no sense. Today I learned I can do it on piano. This will either start driving me crazy or I will start to use it somehow. It’s super cool though and now I know why in the past I couldn’t find the note that was in my head because it seemed in between somehow. I probably needed this 30 years ago, but at least I have it now. Thanks for posting!
Jacob Collier: "So I strive to sing more in tune." Also Jacob Collier in his Moon River video: "So this chord does not exist because I'm singing in microtones."
The men sat with him have quite interesting reactions. When he speaks of something quite that bold, they have a conflicted and yet accepting relationship with what he’s putting forward. As just an onlooker; this man seems to have an awe-inspiring connection with sound waves and how they work.
Jacob sounds slightly more than 14 cents off of that third here, that’s interesting. I think he exaggerated that clash to sound like a diesis so that the audience would get the idea
Yeah I mean 14 cents is barely enough of an audible difference for an untrained ear, and even for a musician as incredible is him that’s a pretty impossible tonal change to consistently replicate. Like I get he’s really good and all but he’s not superhuman, he can’t just tune in 156hz in his brain or some shit and produce that exact frequency.
@@dreamdrifter It was definitely sharp compared to his. As OP said though, sounded a bit more than 14 cents away from his note; it sounded off-puttingly sharp in comparison, and a difference of only 14 cents wouldn’t be THAT jarring.
@@stanleystanley6456 No, he can't "tune in" a specific frequency and he doesn't do that here... he sings a note in relation to the ones he is playing. And while it is indeed pretty hard to hear such small discrepancies between two notes, that is not the jarring effect audible here, it is the two nearly, but definitely not the same notes creating a vibrating effect. Try it with a browser frecuency generator or something, its quite clear.
@@greyhound9967 Yikes. Pretentious much. Is your world view really that narrow that you cant see why people find jacob absolutely mind blowing...? Also, steve vai is FAR from the most technical guitarist...
The problem is, people at Bach's time knew this and figured it out already. There is no perfect way to tune an instrument, it deoends where you aim at and if you want to play together or not. Singers might never have invented the piano, that's why it surfaced so late.
@@AndreasDelleske Yeah all the hype around all this is killing me, it's such common knowledge amongst musicians. I'm missing the rest of the context from the video, but if this is all he said I'd swear he's just overinflating is self-ego by implying that this is some thing he just discovered and is the way of the future.
The piano is equally by out of tune in all keys so that it can give the illusion of being in tune when one modulates to other keys. If some key centers were slightly more in tune the listener would hear the discrepancy. The illusion would be lost.
Quick Science Explanation: The frequencies he plays on the piano are a multiple of 2^(4/12) = 1.25992 apart ("Equal Tempermant") since a major third is 4 half steps and there are 12 half steps in an octave He sings frequencies a multiple of 5/4 = 1.25 apart which sounds nicer to the ear. ("Just Intonation") The "14 cents" he's referring to is 2^(4/12) / 1.25 is approximately 2^(0.14/12)
It’s called perfect pitch, and Perfect pitch is not the epitome of all musicianship. He’s talented, but I can name 30 other pianists or concert pianists who have true musicianship. Jacob is for the pop stars.
people can learn how to do this, it's not superhuman or requiring Collier's obvious gifts, it's just about exposure to that particular interval and practice. he's just singing an interval (a justly intoned 3rd) and holding it against what comes out of the piano (an equally tempered 3rd) so you can hear the difference.
people depend so much on technology and computers to do everything. They forget that even with quantum computers being billions of times more powerful than top of the live gaming rigs, the human brain is still far more powerful. You have to remember that every thing happening in your body, is controlled by your brain. And you're only using no more than 5-7% of your brain's total capacity. Imagine if you could access 100% of it
Not every piano we play will be perfect. Not every meal we eat will be delicious. Not every person we meet will be friendly. But is that really so important? Just enjoy the music, food, and fellowship.
When you think about it, equal temperament is such a mind-bogglingly brilliant innovation. Whoever first thought of it, and did the complex calculations of how to achieve it, was a genius. Without it, any piece of music you can name that involves non-digital musical instruments, that isn’t 100% diatonic (aka really boring), couldn’t exist. That includes most classical music, all of jazz, and most contemporary music.
@@buckylove6918 Well, it took them a hell of a long time to figure it out. It’s not complex when you can use modern electronic technology to determine exact frequencies.
@@buckylove6918 it is complicated if the concept hadn't yet been conceived of in a time without calculators. Would you have figured it out? I doubt it.
Just intonation long precedes digital music and equal temperament. Any non-fretted string instrument can do it simply by shifting position on the finger board (and most classical musicians do this) en.wikipedia.org/wiki/Equal_temperament Also, this isn't a diatonic/chromatic difference. The chord that Jacob played in the video was diatonic (G major). The point is that just intonation/equal temperament affects all chords
@@ryangrose1481 What? Just intonation exists in nature. So, obviously it precedes digital technology and equal temperament. What does that have to do with anything? Whether a chord can be described as chromatic or diatonic depends entirely on its relation to other chords played alongside it. So a chord played in isolation (like Collier’s G chord) is neither. Well, I guess you could call it diatonic because its obviously in the same key as itself, but that’s pretty meaningless. Chromaticism is impossible on a piano tuned to just intonation. I overstated the case to suggest NO chromaticism was possible, in instrumental music prior to digital instruments, without equal temperament, because as you say fret-less stringed instruments, like vocals, can achieve it with just intonation. But it is impossible for other sorts of instruments, and the very complex chromaticism that is now commonplace in music would never have emerged without equal temperament.
I've always thought about this because it fascinates me. When I was playing music with some buddies and we thought about recording some songs we had I tried to look into tuning the guitars to fit better with the key we were playing in instead of just standard equal temperament tuning. We never ended up doing it but it still fascinates me.
Except, your frets are straight and “roughly” spaced, so this only holds for eg one chord at a time. In general, the piano is more in tune than a guitar due to the straight frets, so in practice the temperament problems of the piano are worse on guitar (look up “true temperament” for guitar). But sure, you Can retune for every chord 😄
Except you can’t actually change the temperament of the guitar, unless you are only playing open strings. You’d have to rescale the frets to be in tune with just intonation. Currently, basically all guitars are fretted to reflect the current system of equal temperament we all use. It’s a nice thought, and if you are playing very simple melodies and chord progressions you will hear just intonation as sounding more pure. But if you start to get into more advanced chromatic harmony everything would start to sound out of tune. The reason we have the 12 tone equal temperament scale is actually pretty genius; it allows us to modulate from one key to any other key and it will still sound in tune, hence the term equal temperament.
When I was younger, My uncle explained this to me by telling me about the harmonics you hear in piano notes. Like... if you listen very very closely to a real piano, you'll hear other pitches in a single key press. Like the Note C has a B or B flat in the harmonics, I'm not sure which one but yeah, it's there... but then if you play your tuned B or B flat and compare it to the harmonic B in your C note, it isn't the same pitch, it's a few cents out. Just so happens that Jacob Collier is so good he can sing perfectly in pitch by just instinct because he's a fucking mad man, but there you go.
The fuck I believe he's not only has a perfect pitch, but he also has a perfect frequency that allows him to detect the accuracy of pitch-shifting in microtonal's semitone. Maybe his accuracy is more than your digital tuner.
It’s obvious when he sings the “correct” pitch and then plays the “out of tune” piano key against it (we all can hear the clash between the notes 14 cents apart) but OMG it’s so much harder to perform than he makes it look.
It's not very hard at all...it just takes a little practice...if you can sing on pitch you'd probably be able to sing a pure major third in no time. I can do it..and if I can almost anyone else can too.
@@killboybands1 its not the being able to recite it, it's being able to pull that note perfectly out of the air without having to compare it to something else like people without perfect pitch do. It's not like he played the key a bunch of times first and just went flat a little, he was humming it already and then worked up to it on the keys
Brass players in a section constantly do this. We manually tune every note we play and have the freedom to generate the ‘correctly’ tuned intervals to our section.
That's the main reason I always liked to play 2nd more than 1st. I have pretty good ears and could adjust very quickly to whatever 1st is currently playing/struggeling. I'm also horrible at technical pieces, so a more "melodic" 2nd line is way more fun.
@@pysaumont I have to be honest, in a big band I never listened down to the bass for tuning, I just tune to my section. If I were playing trio with bass, would lock into that.
Here’s a video explaining this: ruclips.net/video/1Hqm0dYKUx4/видео.html It’s mathematically impossible to tune a piano perfectly-all pianos are very slightly out of tune. Edit: If you’re interested in the maths surrounding this, here’s another great video that’s a bit slower and explained better than the one above: ruclips.net/video/cyW5z-M2yzw/видео.html
Fretless and wind instruments are best as you can always adjust intonation in the moment. As you develop your ear you start to adjust naturally and you will play in tune in every key every time. Piano and guitar are the only permanently out of tune instruments I can think of in western music. Everything else is easy to adjust notes as you play
Yeah, the problem is nothing can play in just intonation except non-fretted instruments or maybe a trombone. But then, it would not be exact either. The real problem comes with the sharps vs flats and whether they're ascending or descending. Someone once tried to make a piano that was tuned in just intonation and it literally had different sharps and flats depending on which direction you were measuring your distance. It's kinda crazy. I spent years trying to reconcile this in composition and realized it's just not possible.
I can tell I got very very used to the equal temperament over the years, because when he sang his major third, I could hear it was "too low" for my taste :p (And yes, he plays the major third on the piano first, so we can compare very quickly what he sings to the equal temperament)
@Martin Baldwin-Edwards That is very interesting! I hear what you say. The closest thing I play or listen to, to a natural horn, is an irish whistle, and its tuning is just too dependant on the craftmanship of the maker. I can tell that equal temperament, as in the piano tuning, is the temperament I'm most used to, because of fretted stringed instruments, synthesizers and virtual instruments, which are often re-tuned to equal temperament. And I could argue that these instruments make up for the most everyday music that is being produced these days, pop music, electronic music, rock music. So, that would be why I'm more used to equal temperament, and you're used to other temperaments because of your experience with other types of instruments?
Easy demonstration for anyone with a guitar: Tune the top and bottom strings on your guitar to exactly the same E/e' pitch. Strike the harmonic over the 4th fret on the lowest string, E--it will sound as a pure (tempered) third over the open string, a b' natural. Now play, against that, the 4th fret on the 1st string. That will be an equal temperament b'. Here's your chance to compare the two. Only one is a real third. You will also notice the harmonic node isn't directly over the fret but a little closer to the nut. That is the distance of the 14 cents in his description of the problem.
There's really a lot of potential reasons, but I'd guess the most likely one is just being nervous and having something to comfort yourself. Personally I sometimes will rub my legs when I'm stressed out. But then again, I am autistic, so your mileage may vary.
It's a pacifying behavior linked to nervousness, he feels uncomfortable and exposed being on stage, in fact every guy up there exhibits body language characteristic of uncomfort.
Sorry everyone, if you can hear the difference in pitch he's much flatter than he is saying. He isn't actually singing a consistent pitch; in fact when he includes the B (major 3rd and yes I have perfect pitch) he lowers his note to make it seem more out of tune.

If anybody is wondering, the reason he says "you guys know this" is because he is speaking at MIT.
Does this mean that you could program a keyboard to play in just intonation? The keyboard would just tune itself to whatever key you’re playing in? (Of course you couldn’t modulate or play chromatically.)
@@johnlanou yes, most DAWs should allow the tuning to work like that, you could also build one using MAX/MSP or PureData (the freesource analog), there is always the digital audio dilemma regarding harmonics but most of the classic synths sounds we know today were built using different tuning systems !
@@lol-zp1ps other instruments are so easy to tune, it wouldn't be much of a problem. Most wind instruments are fine tuned multiple times through a performance (slight adjustments to mouthpiece and reed position are never ending realities of orchestral life. Guitars and nearly all strings are easy to tune. In fact I'd bet "concert tuning" with no piano present would probably be closer to key specific just intonation...
@@lol-zp1ps you are correct. I have the jargon all mixed up, it's been a while. I just mean, so much of the playing I did was sans piano, probably it made us do less equalizing while we refined our intonation.
@@lol-zp1ps and there was often a theme in our repertoire so the tendency would be to pitch for they key we were in.
Jacob has converted us to join in his conspiracy against equal temperament.
I was already well aware of it. This is precisely what I hate about most instruments.
@@troysmithfr If you knew for real you would know that there's no solution. If you had to play all the intervals of a melody with perfect ratios and then return to the root you would find that the root you ended on is not the same note you started from
@@Davide_LP I'm aware of that, I never said I didn't deal with it lmao.
@@Davide_LP That’s for instruments with a fixed set of notes. Anything with an arbitrary amount of precision could be written for in just intonation with no problem. Jacob has talked about retuning guitars in between takes, so the DAW essentially allows him to do this with fretted instruments as well. Most music doesn’t even involve key changes at this point and the home tone drifting by commas doesn’t bother me. Everything else is a matter of tooling and shared language, which are both getting better
@@Davide_LP Exactly this. Equal temperament is the best we've got to be able to play in all keys using a 12 tone system, so instruments basically have to use it.
Imo, It's just something that we've gotta live with since 99% people don't even know it's out of tune. For people who do know about it, it's something we should work around. Drop in a little just intonation and maybe even totally different tuning systems here and there, similar to what Jacob does. Too much spice ruins the dish.

This makes musicians with perfect pitch all the more special.
Perfect pitch can do that for ya
Not so stunning if you practice singing with pure/just intonation. See WA Mathieu, Harmonic Experience. :)

@Martin Baldwin-Edwards indeed..
I am German and our grammar is a little more complex then (than? Never get that right) English grammar is.
When I form a complex sentence with a rarely used case, autocorrect tries to tell me it is wrong, even though it's perfectly right.
Sometimes autocorrect doesn't even know a case modified word exists.
And this has consequences on people's speech patterns, and writing styles. Germans now, speak and write way simpler than Germans 50 years ago.
It's some weird degeneration of speech.
amazing isn't he. I want to be him when i grow up.......problem is I'm already near double his age.
Doesn't that sentence mean computers know more than he does?
@@lloydaran I believe it's irony. The way I read it, he's saying "computers think they know better than me," but what is 'in tune' to a computer may be in fact out of tune using a different tuning system, like just intonation.
@Martin Baldwin-Edwards I'd like to offer a counter argument. Usually computer programmers don't put basic knowledge into their work. Programmers do just that, -they program. All the knowledge conveyed by their final work is provided by trained professionals in that field. Programmers who make software for MRI machines don't fill it with mediocre medical knowledge. While I for one keep autocorrect disabled as much as possible, I know for fact that it has been made with the help of linguists and people who are knowledgeable on the subject.
There's a lot to say about this, but I believe it's important to remember that portraying emotion and expressing one's self are both matters inherently subjective and no amount of even expert knowledge will ever be able to fully represent everyone.
Being able to modulate sure is fun though.
Great point. Then again Jacob modulates to G half sharp in one of his pieces, if I recall correctly. =D
But you lose out on all the intricate tones and moods of each key *actually* sounding different to one another!

You can hear a slight wobble in the sound when he sings with the piano, this is what happens when you play two notes slightly out tune from one another.
This guy is legit an alien.
By the way this is one of the reasons vibrato got into classical singing. They felt there is a gap and wanted to bridge it. And it's more forgiving, you can hide your intonation a little :) and listeners like it too, even as listeners we might feel it.
Singers will sooner or later feel the mathematical relations.
100% an alien! :)
@Martin Baldwin-Edwards I've noticed this too!! For some singers their vibratos are out of tune and don't match the accompanying music. I only recently learned I'm quite sensitive to microtones & intonation and I'm slowly teaching myself the technicalities of why my ears pick up that weird dissonance. Your comment helped me figure out another puzzle piece.
One opera singer i respect because she has a strong vibrato that 90% of the time sounds correct and nice, is Sarah Brightman. There's a reason she's one of the greats. I think she can tell where to tune her voice up or down so the midpoint of her vibrato sits nicely on the music.
Actually each piano key produces a variety of different tones and notes, which are unique for each Piano. What happens is that your ear just picks up the dominant tone.
@Martin Baldwin-Edwards Maybe, but it is still interesting. Learned while tuning my piano and seeing the sound frequencies on the computer.
“Disregard what computers know” funny.
"How does no one know this stuff?"
Actually, I feel like that is widely known! ...at least for vocalists and (fretless) stringed instruments etc.
If we rehears in our vocal ensemble we never sing after the piano, especially not for those dirty equal temperament thirds. :P
We also do this in our band rehearsals!
I think he is speaking to those of us who make modal music using discrete, predetermined intervals… keys, frets, buttons etc. Especially people using grid based DAWs and sequencers.
Most modern music tends to fall into this category. I like it, but things like Terry Riley’s Shri Camel are among my favorites.
Most people are also self taught, as the last 25 years has seen many primary schools cut their arts educational programming. This just leads to a less informed, more rigid population, especially as most products are designed and geared towards creating 16 bar sequences in standard time with a consistent clock.
I am not saying that is bad, though… It just leads to a predictable and repetitive track, and truth be told, dancing to trance music into the wee hours of the morning is a pretty satisfying experience, in a way that not many other genres can lay claim to…
The best part about it is, now we all know because dude is on a mission to unlock music from the bonds of our programmatic musical overlords…
The irony is that Vincenzo Gallilei (father of the mathematician/astronomer) described it 500+ years ago and here Collier is trying to explain it at, checks notes, shakes head, MIT.
@@AlchemicalAudio The fun thing with DAWs is, you can adjust the tuning of each note played down to a cent.
This is why in chamber choir you try to avoid relying on the piano to give you a harmony: you should be able to do better than the piano.
Depends on the choir :)
I sang in madrigal choir and we tuned with a pitchpipe.
This a sign for you to finally learn the violin jacob...
I loved the part where he actually tunes the piano
Ikr!
Here he is explaining something called equal temperament. Western music uses 12 notes of equal distance apart. But with having each not equal in distance, each note is just slightly off. So in short, he sang the perfect third against the pianos third that is slightly out of tune. If he were to tune it then playing in other keys would very off, but he can use the perfect harmony when singing because the tuned notes will not clash with other notes.
That is why a good string quartet playing a triad sounds so rich and deep, because they play the thirds in tune.
Choirs as well. They sing in just intonation, perfectly in tune for the key they are in, which can lead to some interesting effects, such as ending several cents higher or lower than they began, all simply because of the natural tendency to tune each chord justly. Across many chord changes, this can force the tonal center away from the original.
Ironically, the only way to combat going out of tune is to sing [slightly] out of tune, on purpose.
@@obiwanda in my choir we literally practice singing various notes in the scale "sharp" or "flat" to actually formalise this. It is a matter of opinion what method of tuning sounds "better" or "worse", so obviously not everyone needs to do it, but it's still going to sound fine if you do sing "out of tune".
Or literally any wind/string instrument/voice that is properly accounting for just intonation.
@@obiwanda Also interesting, choirs who don't use A440 tend to stay closer to in-tune than those who don't. It seems that there's something more natural about A434-436 that makes it easier to hold.
Also, alot of those old cathedrals you find in europe were built to have natural resonance in them when singing, and some of them don't work as-designed at A440
It’s really simple, folks. Bach popularized the “well-tempered klavier” with his book of the same name which exploits the equal temperament by enabling us to play in every key. Moreover, in each key he travels to as far distant keys as aesthetically possible and back without any of them sounding bad. This means that when you play chamber music with piano or any other instrument which cannot adjust its pitch, you play in equal temperament. That is, you adjust to the piano. When you go back to playing with other instruments like your own which adjust easily in real time (strings, woodwinds, brass, voice, mainly) you can play “perfect” intonations, but you’ll be adjusting constantly, which is what we do. It requires practicing your pitch in various ways, but is quite doable for any good musician. It’s not rocket science. Actually, it’s acoustic science. But we just use our ears and learn how to make it work. It’s easy once you grasp it.
"Well-tempered" is not equal tempered
Its not about playing in every key, its about playing in every octave possible while still avoiding dissonance in melodic intervals.
Im not sure if it was pythagorus, but a greek philosipher made an instrument using true equal temperement to try to prove that the universe held itself together mathematically and failed miraculously when he came across multiple intervals that would sound horrible together (the wolf interval i believe its called).

@@ghujdvbts If you're very good, you feel the differences, I don't. it's like singing. But mostly you stick to the other instrument's tunings. You will notice that string players very often use vibrato to bridge the gap and also to cover up initial minute pitch glitches.
Nope. There's a group of people obsessed with purity, sometimes it's political, sometimes it's how to tune a FUCKING piano... but in whatever way it manifests those people can't just enjoy life, shit's always got to be a problem. A problem no one but them can even detect.
The closest I can even get to this level of scrutiny is probably 60hz strobing from LEDs and fluorescent lights... it's mildly annoying. If I had that level of give a shit about every little thing in life I probably would've ended myself by now lol.
That's the cool thing with classical guitars: we can intonate by fretting a note and then push it down or up. Use it all the time at key points in the music (e.g. closing chord).
You can't bend a note down tho lol and the major third is sharp. Often people tune their G string slightly flat, so they can play the major thirds on there justly intimated and then just bend the G string "sharp" when playing other notes on it like a perfect fifth in relation to something below it
@@joshuagavaghan224 you absolutely can bend a note down tho
@@pedrobambinoperez2572 how? Without a floating bridge?
@@joshuagavaghan224 the only way to do it is bend the neck in, but that will bend every note flat if you’re playing a chord. Not to mention it’s not a quick easy motion like bending a string.
@Ryandal Gilmore applying force perpendicular to the neck can indeed only stretch the string.
However you can apply a force parallel to the neck, towards the body to loosen the side of the string that produces sound and consequently lowering the pitch, or on the contrary towards the head, pulling and stretching the side of the string that produces sound, which will result in a higher pitched sound (but might as well push perpendicularly to the neck for a higher pitch).
"You guys know this because Pythagoras figured it out" I hate it when people say stuff like this. Just because you understand a concept doesn't mean you can automatically apply it to every single application immediately.
I also figured out equal temperament as a teenager, and it was exactly those two notes - G and B just below middle C, that made me understand it. Before digital tuners, tuning up a guitar by ear was pretty challenging, especially to get the G and B just out enough to make the rest sort of play in tune-ish...
Just a pure genius. I’d cut off my left pinky to have theory like this guy.
I experienced this during a choir rehearsal: the conductor asked the piano player to play C and G (in equal temperament fifths are narrowed by 2 cents, so it's pretty much in tune) and asked altos to sing E. They sang it and tuned it and then the pianist played the tempered third. Same result :)
He will be frustated to hear a massive dissonance from an "in tune" guitar.
Just tune it flat and bend the strings to get it in tune.
I saw this video 2 years ago and it made no sense. Today I learned I can do it on piano. This will either start driving me crazy or I will start to use it somehow. It’s super cool though and now I know why in the past I couldn’t find the note that was in my head because it seemed in between somehow. I probably needed this 30 years ago, but at least I have it now. Thanks for posting!
To be able to store the true sound of a chord or a note in the mind is a skill by itself. Kudos to all who can actually do that.
When it comes to intonation and tuning for guitars, we've got chorus pedals!

Don’t mean to change your mind but for classical musicians this is basic stuff
Jacob sounds slightly more than 14 cents off of that third here, that’s interesting. I think he exaggerated that clash to sound like a diesis so that the audience would get the idea
Yeah I mean 14 cents is barely enough of an audible difference for an untrained ear, and even for a musician as incredible is him that’s a pretty impossible tonal change to consistently replicate. Like I get he’s really good and all but he’s not superhuman, he can’t just tune in 156hz in his brain or some shit and produce that exact frequency.

@@dreamdrifter It was definitely sharp compared to his. As OP said though, sounded a bit more than 14 cents away from his note; it sounded off-puttingly sharp in comparison, and a difference of only 14 cents wouldn’t be THAT jarring.
@@stanleystanley6456 No, he can't "tune in" a specific frequency and he doesn't do that here... he sings a note in relation to the ones he is playing.

The piano is sharp on purpose. Look up John Frusciante out of tune, similar concept with the major 3rd
The piano is equally by out of tune in all keys so that it can give the illusion of being in tune when one modulates to other keys. If some key centers were slightly more in tune the listener would hear the discrepancy. The illusion would be lost.
the fact that he can hear the difference between a note 14 hundreths of a semitone higher or lower is mind fucking boggling itself
14 cents is not a small amount. It’s possible if you have perfect pitch and a trained ear.
If you could hear the fact that his voice and the piano weren't in tune, you too can hear the difference.
Jacob: cut that out
Piano:*quickly tunes itself
Stunning. I ran my fancy piano soundfont on a Pythagorean temperament once and it was pretty weird. I love the inharmonicities. Sometimes
Quick Science Explanation:
The frequencies he plays on the piano are a multiple of 2^(4/12) = 1.25992 apart ("Equal Tempermant") since a major third is 4 half steps and there are 12 half steps in an octave
He sings frequencies a multiple of 5/4 = 1.25 apart which sounds nicer to the ear. ("Just Intonation")
The "14 cents" he's referring to is 2^(4/12) / 1.25 is approximately 2^(0.14/12)
The beat between his voice and the piano key.....constant and perfect 😂
We teach this to our wind players in 7th grade. The concept is very simple. Eliminate the waves. Very young players can learn how.

It’s called perfect pitch, and Perfect pitch is not the epitome of all musicianship. He’s talented, but I can name 30 other pianists or concert pianists who have true musicianship. Jacob is for the pop stars.
Fricking amazing!
people can learn how to do this, it's not superhuman or requiring Collier's obvious gifts, it's just about exposure to that particular interval and practice. he's just singing an interval (a justly intoned 3rd) and holding it against what comes out of the piano (an equally tempered 3rd) so you can hear the difference.

Jacob is pumping and dumping that comma I see
Perfection in imperfection
When you think about it, equal temperament is such a mind-bogglingly brilliant innovation. Whoever first thought of it, and did the complex calculations of how to achieve it, was a genius. Without it, any piece of music you can name that involves non-digital musical instruments, that isn’t 100% diatonic (aka really boring), couldn’t exist. That includes most classical music, all of jazz, and most contemporary music.
Its not complex calculations
@@buckylove6918 Well, it took them a hell of a long time to figure it out. It’s not complex when you can use modern electronic technology to determine exact frequencies.
@@buckylove6918 it is complicated if the concept hadn't yet been conceived of in a time without calculators. Would you have figured it out? I doubt it.
Just intonation long precedes digital music and equal temperament. Any non-fretted string instrument can do it simply by shifting position on the finger board (and most classical musicians do this)
en.wikipedia.org/wiki/Equal_temperament
Also, this isn't a diatonic/chromatic difference. The chord that Jacob played in the video was diatonic (G major). The point is that just intonation/equal temperament affects all chords
@@ryangrose1481 What? Just intonation exists in nature. So, obviously it precedes digital technology and equal temperament. What does that have to do with anything? Whether a chord can be described as chromatic or diatonic depends entirely on its relation to other chords played alongside it. So a chord played in isolation (like Collier’s G chord) is neither. Well, I guess you could call it diatonic because its obviously in the same key as itself, but that’s pretty meaningless. Chromaticism is impossible on a piano tuned to just intonation.
I overstated the case to suggest NO chromaticism was possible, in instrumental music prior to digital instruments, without equal temperament, because as you say fret-less stringed instruments, like vocals, can achieve it with just intonation. But it is impossible for other sorts of instruments, and the very complex chromaticism that is now commonplace in music would never have emerged without equal temperament.
why did i read this as "jacob collier turns into the piano"
That's one of guitar's advantages: depending on the song you wanna play, you can tune it especially for the song, if you have good enough ears.
I've always thought about this because it fascinates me. When I was playing music with some buddies and we thought about recording some songs we had I tried to look into tuning the guitars to fit better with the key we were playing in instead of just standard equal temperament tuning. We never ended up doing it but it still fascinates me.
@@mastod0n1 that is definitely possible!
Open tunings have entered the chat
Except, your frets are straight and “roughly” spaced, so this only holds for eg one chord at a time. In general, the piano is more in tune than a guitar due to the straight frets, so in practice the temperament problems of the piano are worse on guitar (look up “true temperament” for guitar). But sure, you Can retune for every chord 😄
Except you can’t actually change the temperament of the guitar, unless you are only playing open strings. You’d have to rescale the frets to be in tune with just intonation. Currently, basically all guitars are fretted to reflect the current system of equal temperament we all use. It’s a nice thought, and if you are playing very simple melodies and chord progressions you will hear just intonation as sounding more pure. But if you start to get into more advanced chromatic harmony everything would start to sound out of tune. The reason we have the 12 tone equal temperament scale is actually pretty genius; it allows us to modulate from one key to any other key and it will still sound in tune, hence the term equal temperament.
I'm totally in love with this dude.
pompous dude innit
Brilliant! That’s what I’m talking about. I’ve been working on Just Tuning but it’s a hard road!
This is why Jacob should explore other equal temperament systems, like 31-TET
Bach lehman is nice
literally every choir singer knows about this.
The piano isn't out of tune: it's tuned differently
When I was younger, My uncle explained this to me by telling me about the harmonics you hear in piano notes.
Like... if you listen very very closely to a real piano, you'll hear other pitches in a single key press. Like the Note C has a B or B flat in the harmonics, I'm not sure which one but yeah, it's there... but then if you play your tuned B or B flat and compare it to the harmonic B in your C note, it isn't the same pitch, it's a few cents out.
Just so happens that Jacob Collier is so good he can sing perfectly in pitch by just instinct because he's a fucking mad man, but there you go.
The living LEGEND!
Drum teachers: NOT MY TEMPO
Collier: Not my tuning system
I love how smoothly he integrates complaints or addresses things 5hat happen in the audiencr
The fuck
I believe he's not only has a perfect pitch, but he also has a perfect frequency that allows him to detect the accuracy of pitch-shifting in microtonal's semitone. Maybe his accuracy is more than your digital tuner.
I will wager to say that most good high school band/orchestra/choir directors teach this to their students. Its a fundamental to ensemble playing.
haha yes, equal tempering made popular by Bach is still not exact.0:28 So cool you actually hear the beats (? Schwebung) between the two notes.
Some can put in their two cents while Jacob puts in his 14 cents.
It’s obvious when he sings the “correct” pitch and then plays the “out of tune” piano key against it (we all can hear the clash between the notes 14 cents apart) but OMG it’s so much harder to perform than he makes it look.
It's not very hard at all...it just takes a little practice...if you can sing on pitch you'd probably be able to sing a pure major third in no time. I can do it..and if I can almost anyone else can too.
@@killboybands1 its not the being able to recite it, it's being able to pull that note perfectly out of the air without having to compare it to something else like people without perfect pitch do. It's not like he played the key a bunch of times first and just went flat a little, he was humming it already and then worked up to it on the keys
@@MajesticSkywhale He plays the Triad and then root and 5th , then sings the 3rd. But He also has perfect pitch.
Ah yes, Jacob spilling music tea as usual
Brass players in a section constantly do this. We manually tune every note we play and have the freedom to generate the ‘correctly’ tuned intervals to our section.
As a double bass player, I constantly do the same. I don’t know why other musicians in the band don’t acknowledge that!
That's the main reason I always liked to play 2nd more than 1st. I have pretty good ears and could adjust very quickly to whatever 1st is currently playing/struggeling. I'm also horrible at technical pieces, so a more "melodic" 2nd line is way more fun.
@@pysaumont I have to be honest, in a big band I never listened down to the bass for tuning, I just tune to my section. If I were playing trio with bass, would lock into that.
I was a never a great trumpet player in school, but even I moved my finger slide thing out on certain notes.
If you were the string section you'd be working the hell out of the vibrato to cover it up! Yay mush!
and yet, he can't make actually good music to save his life
Here’s a video explaining this: ruclips.net/video/1Hqm0dYKUx4/видео.html
It’s mathematically impossible to tune a piano perfectly-all pianos are very slightly out of tune.
Edit: If you’re interested in the maths surrounding this, here’s another great video that’s a bit slower and explained better than the one above: ruclips.net/video/cyW5z-M2yzw/видео.html
i thought the jacob was doing the "sheesh" pose on the thumbnail
Fretless and wind instruments are best as you can always adjust intonation in the moment. As you develop your ear you start to adjust naturally and you will play in tune in every key every time. Piano and guitar are the only permanently out of tune instruments I can think of in western music. Everything else is easy to adjust notes as you play
Wait, can't you literally tune a guitar to whatever you want?
@@brent_peterson sure but you can't adjust the spacing of the frets
@@justafase Oh, I see what he meant now
@@justafase People have made, and people have played, guitars with fretboards with frets spaced for 19- and 24-equal and possibly other temperaments.
@@justafase There are fretless guitars. Actually frets were added later, for ease of playing.
I love how the guy in the middle ist just smiling and shaking his head like, "you got to be kidding me, this guy lives in a whole other dimension"
I was intially impressed with him like most people. But after binging his videos the more and more I feel like he's a griffter
Yeah, the problem is nothing can play in just intonation except non-fretted instruments or maybe a trombone. But then, it would not be exact either. The real problem comes with the sharps vs flats and whether they're ascending or descending. Someone once tried to make a piano that was tuned in just intonation and it literally had different sharps and flats depending on which direction you were measuring your distance. It's kinda crazy. I spent years trying to reconcile this in composition and realized it's just not possible.
I can tell I got very very used to the equal temperament over the years, because when he sang his major third, I could hear it was "too low" for my taste :p
(And yes, he plays the major third on the piano first, so we can compare very quickly what he sings to the equal temperament)
@Martin Baldwin-Edwards That is very interesting! I hear what you say. The closest thing I play or listen to, to a natural horn, is an irish whistle, and its tuning is just too dependant on the craftmanship of the maker.
I can tell that equal temperament, as in the piano tuning, is the temperament I'm most used to, because of fretted stringed instruments, synthesizers and virtual instruments, which are often re-tuned to equal temperament. And I could argue that these instruments make up for the most everyday music that is being produced these days, pop music, electronic music, rock music. So, that would be why I'm more used to equal temperament, and you're used to other temperaments because of your experience with other types of instruments?
@Martin Baldwin-Edwards Super interesting stuff :D
Easy demonstration for anyone with a guitar: Tune the top and bottom strings on your guitar to exactly the same E/e' pitch. Strike the harmonic over the 4th fret on the lowest string, E--it will sound as a pure (tempered) third over the open string, a b' natural. Now play, against that, the 4th fret on the 1st string. That will be an equal temperament b'. Here's your chance to compare the two. Only one is a real third. You will also notice the harmonic node isn't directly over the fret but a little closer to the nut. That is the distance of the 14 cents in his description of the problem.
Brilliant 🙏👏🏼👍🏼
Why is that guy stroking his legs near Jacob???
He regrets wearing shorts and feeling like an awkward elementary school student on that stool.
Mosquitoes mayb
There's really a lot of potential reasons, but I'd guess the most likely one is just being nervous and having something to comfort yourself. Personally I sometimes will rub my legs when I'm stressed out. But then again, I am autistic, so your mileage may vary.
It's a pacifying behavior linked to nervousness, he feels uncomfortable and exposed being on stage, in fact every guy up there exhibits body language characteristic of uncomfort.
@@infamous8179 Sitting on a stool is naturally uncomfortable though
Jacob, welcome to early music
He even *looks* like a Jacob, damn.
you know what, strangely, you make sense… 🤔
Sorry everyone, if you can hear the difference in pitch he's much flatter than he is saying. He isn't actually singing a consistent pitch; in fact when he includes the B (major 3rd and yes I have perfect pitch) he lowers his note to make it seem more out of tune.
MY BAND TEACHER TAUGHT US EQUAL TEMPERAMENT IN HIGH SCHOOL! We sounded so much better than other bands because of it
what was his approach?
Wow you must be so proud of your brother 😏
