Humans & other mammals have two vocal chords that one airway blows between. Hefele touches tongue to top of mouth for smaller (higher pitch) overtone resonance chamber after tongue in addition to larger (lower pitch) resonance chamber before tongue. Birds have two single vocal chords that stretch across each airway of each of two lungs and they can and do modulate their vocal chords independent of each other. Cornell has a web page with animation of bird vocal chords.

This is the first time I've ever seen a non-Mongolian non-male do this. Unbelievably great job! Are female's overtones generally higher than male's, due to the register difference of their natural voices?

[@alexandrapedersen829]

Here's a mongolian woman doing throat singing: kzbin.info/www/bejne/sJa4nKqhpKh2btU It should be noted that what Anna-Maria is doing is not throat singing but something called polyphonic overtone singing.

[@stigmellem]

I'm just an amateur and started following you 3 or 4 years ago. When I was 16-17 I listened carefully to one key at the time on the piano, trying to hear the overtones. Afterward I went into the kitchen. We had guests. They spoke to me I could just hear overtones from their voices LOL This year, 30 years later, I learned that vocalists also can change the "overtones" with their vocal chords. What a wonderful instrument you are in control of!

[@Gleesonglee]

I have taught overtone singing for 30 years. I am a bass baritone so I can't demonstrate how to do the high pitched stuff unless I lead with the muscle rather than the vocal chords, so it is quite an exertion. After discovering overtone singing I doubled my vocal range and was able to generate maximum musical notes of 110 decibels. I have been loud enough to run 600 Spontaneous Choirs of up to 600 outdoors with no technology. It is well worth learning. The next revolution is to shape the throat to suit the note from the mouth, so the one voice chord

[@koshersalaami]

There’s a part of the explanation missing: what the overtones actually are. This is best visualized if you take a stringed instrument. Guitar, violin, mandolin, banjo, dulcimer, cello, whatever might be handy. You pluck a string. It vibrates along its whole length at a pitch called the Fundamental. That’s the note you’re playing intentionally. But while it vibrates along its whole length, it also vibrates in halves, each half at double the speed of the fundamental. And in thirds at three times the speed of the fundamental. And in fourths at four times, etc. When you double speed, you go up an octave. When you triple, you go up an octave and a fifth. When you quadruple, you go up two octaves (double twice). Quintuple, two octaves and a major third. Sextuple, two octaves and a fifth (double the speed of thirds, so an octave higher). When you pluck the string, you actually hear all these notes at once, you’re just not aware of it. If you take your stringed instrument, pluck a string (or bow it), and touch it very lightly dead center, which is where you’d play an octave up, on a guitar at the twelfth fret, your light touch will deaden the fundamental. However, because your finger is touching where one half ends and the other begins, it doesn’t deaden the first overtone, so you hear this sort of bell-like note. Overtones are also called harmonics and if you’re a string player the technique I’m describing is called playing a harmonic. If you pluck the string and touch it lightly at either 1/3 point, you’ll get the overtone that’s 3x fundamental. Where you’ll find one of them is where you’d play a fifth higher on any string. On a chromatically fretted instrument (guitar, banjo, mandolin, electric bass, but not a dulcimer) that would be at the seventh fret. You can hear these overtones in your own voice easily, just not nearly as loud as Ms. Hefele produces them. Just sing a low note, hold it a while, and sing the word “wow” Very Slowly. You’ll hear some sort of faint flute-like notes go up and down above your note. As to using your mouth to filter overtones, you do it constantly. That’s what vowels are (as shown by the wow exercise). However, vowels don’t typically filter out everything but a single overtone.

[@xanblacq]

Great explanation. Thanks for taking the time to write it.

[@ZijnShayatanica]

Thank you for this comment!! I don't play any string instruments, but I can more easily understand what an overtone actually IS based on your explanation. 😊

[@key37raminus]

That's a very nice explanation! Thanks for mentioning vowels, I learned about them when studying phonetics, but it's hard to piece it all together. The mouth shape acts as a filter for the harmonics, shaping them into different vowels. So this singing technique is like "extreme voweling", where you shape the harmonics to damp all but the overtone you want? And with vowels it's more like a rough shape, making the 2nd stronger than the 3rd, for instance. Is that right?

[@thederpydude2088]

That "wow" example is such an easy and accessible demonstration of this 🤔 It might come in handy if I ever try explaining all this to a friend XD I have an idea of how to filter the overtones, but does anyone know how I could make it sound louder? I mainly struggle with getting it to sound more loud and prominent than the fundamental.

I've heard split tones ( about a 5th above the fundamental)before in rare instances by some gifted vocalists when hitting a sustained note at a high point in the song) , but after being amazed at what I heard, I wrote it off to being sufficiently stoned and imagined it all. This goes way beyond anything I've ever heard. She has complete command of every interval and can take the notes in opposite directions at the same time.

[@skyletwings5711]

The good thing about overtone singing is that they always harmonize with each other, as the harmonic relation is built-in. :-)

[@Reckless150681]

I think it's worth sharing that these are very analogous to partials for brass players and why changing the airflow and embouchure produces distinct tones rather than a chromatic scale. In fact, the physics are identical.

[@thatbandgirl2535]

I play trumpet, can you tell me how to play overtones?

[@Reckless150681]

+XxTrumpetCheerxX Let me be a little more clear. As far as I know, you can't play simultaneous overtones on brass instruments in the way she's doing it, but the notes you CAN play are identical to that she is singing. As you probably know, pitch is generated by a vibration. For stringed instruments, it's primarily the string, while in wind and brass instruments it's primarily the bell, but I'll focus on brass instruments. Now there's a concept in physics called standing waves, which is how brass instruments work. Basically, with an open tube, you create waves of air pressure that can only exist in very distinct frequencies. Translated to music, think about your open fingering (concert Bb, F, Bb, D etc. or trumpets' C, G, C, E, etc.). You can use your lips and airspeed to adjust the pitch a little bit in each direction, but for the most part, if you go too far you completely change pitch. Now if you took the frequency of each of those pitches, you'll find them to be somewhat related. If you take your lowest note and divided its frequency by 2, you'll find that all of the notes in any given fingering are just multiples of that notes. Now a trumpet is what's considered an open tube, because it's essentially one great, long, twisted tube that's open at both ends (the bell and the mouthpiece). In an open tube, standing waves can only exist in INTEGER MULTIPLES of a low, fundamental frequency. In other words, the same thing that is happening with your trumpet. When you change partials (go from C to G or G to C, etc.), you don’t actually change fingerings, and therefore you don’t really change the length of the tube, right? You’re just changing the frequency, and the only frequencies you can produce are integer multiples of your lowest, fundamental frequency, which high brass instruments can’t actually play. I can play them on trombone and euph, however, and tubas can play them. In music, these are a brass player’s PEDAL NOTES. In physics, doubling the frequency gives you an octave. So if we have a fundamental frequency (in other words, a pedal note, or a note that exists in low brass instruments but not in high brass instruments) of 100 Hz (that’s actually extremely low, but 100 is a nice, even number), then the next partial is 200 Hz. This is every brass player’s first partial, or your lowest note on any given valve combination. Next is 300 Hz. It’s three times the fundamental, but it’s not double of 200, so it’s not an octave. That makes sense. What’s above your C? A G. They’re not the same note. Next is 400, and that IS a double of 200. Above your G is another C, and that is definitely an octave. Next, doubling 400 gives us 800. That means that there are three notes in between the next octave, and that happens to be true. Between your mid-range C and your high C are three notes: E, G, and a flat Bb. All of these notes (integer multiples of the fundamental frequency) are known as the HARMONIC SERIES, and each separate, individual note is known as a HARMONIC, and on brass instruments they are known as PARTIALS. Ok, so that explains the hard physics (hopefully). What’s interesting, however, is that when you play the fundamental, you’re actually playing ALL OF THESE NOTES AT THE SAME TIME. The thing is, because they’re all integer multiples of the fundamental, your ear only picks out the fundamental. If you took all your separate notes and gave each of them a different volume, if you gave your fundamental just a teeny little bit of volume, you will always hear the fundamental. Everything else forms tone. The different intensities distributed to each note in the harmonic series is what defines tone and timbre. For example, a trumpet actually has quite low intensity in its fundamental, but its third harmonic (I think) is quite strong. That’s why it sounds so bright. You only hear the lowest note, but the effects of the high note still reach you. A trombone has a lot of its fundamental and I think the fifth harmonic, which is why it sounds mellower than a trumpet but still has some bite to it. Basically, different shapes create different tones. All of the tones of the harmonic series above the fundamental are called OVERTONES (hence the video title, overtone singing). Which finally brings us back to the video. She is essentially changing the shape of her cavities to let different harmonics ring out. (Metal guitarists do something similar (in concept, if not in practice), where they will let a string ring out, then quickly mute it a little. This has the effect of cancelling the fundamental and ONLY letting the high harmonics play out. This is how they get those squealies.). You’ll notice that all of her extra higher notes are somewhere in the harmonic series, because she’s only physically capable of producing them based on the physics from above. To recap: physics only allows specific notes to be played at a given tube length. This principle holds true for brass instruments and singing. I hope this makes sense, and I didn’t make any mistakes in my physics. If not, feel free to ask more questions (and for others to jump in and help)

this is maybe the best video about music in the whole internet, very clever explanation and clear demonstration also the skill and precision level is astonishing, Anna plays with overtones like playing the piano, just wow

[@jonpritzker9709]

truly amazing

[@BrookJolley]

Craziest shit, lol I actually did figure out how to do this shittily in 9 minutes by watching this.. but if i do it in front of my dog he loses his mind. If you can hold a C4 then move your mouth around bigger to smaller and change tongue positions you'll hear some of them with little/no effort. It's in the mouth/tongue shape. You stay singing the same note with similar pressure but moving the mouth around creates differentiation in tones.

[@kennydoomster]

this technique reminds me of abes odyssey...or the second one

[@vamshikrishna-fu2ev]

You are simply awesome Anna Maria. Congrats on your hard work.

[@KreativeInstinct]

never even heard of polyphonic before, just listened to her in the first minute and i can do it, now to practice and get as good as her, pretty nifty

[@TheFloridaPappy]

I get the overtones and the fundamental, but what are the mechanics of how the notes are created simultaneously by your vocal chords?

[@RayhanTee]

The fundamental is created by the vocal folds but the overtones and filtered out by the filter of our instruments, in this case, mouth, tongue. Which in turn, modifies the space in our vocal tract. Thus filtering out unwanted overtones of your choice once you've learnt to do it.

[@Gongasoso]

Rayhan Tee Is it somehow intuitive or, say, this note requires a certain change in the tongue, but the next semi-tone requires a change in the mouth?

[@RayhanTee]

Gongasoso Once you know ho wto do it it is somehow intuitive and you might not even know what is going on. Every semi tone requires a slightly different tongue position or rather, only the back of the tongue. Anna-Maria Hefele posted a new video on this, do check it out! :D

[@lukeroe3434]

TheFloridaPappy it's created by the movement of the tip of your tongue behind your dental ridge. The only thing that you're vocal cords have to do with the sound is the production of the initial pitch

[@mgc7199]

The vocal chords produces all the notes. The cavity of mouth and sinus determines what wave(s) are emphasized and slightly change the vowel in the process. (small cavity vowel like 'e' changes to 'u' upon expanding it (drop the back of the tongue slightly), emphasizing a lower overtone.

What was the name of the Folk Song? I am surprised few people asked.
