Polyphonic Overtones MADNESS! Opera Singer breaks down how through software!

And now for something completely different...
Many of you know how much of a vocal nerd I am, and many more know that I compose and produce my own music (music covers, video game soundtracks, and more!) So having the opportunity to hop into some software and show you Anna-Maria Hefele singing in polyphonic overtones and show you WHAT THAT LOOKS LIKE. . . is my bag of tea!
Join professional opera singer Elizabeth Zharoff, as she breaks down Anna-Maria Hefele singing in polyphinic overtones for the first time on the channel!

As a musician and sound engineer, this woman's talent amazes me. She's basically a human quantizer + resonance filter all rolled into one. I've used control voltage to "play a filter" on high resonance, using the upper harmonics as an Oscillator, but this woman is doing it with her voice! I'm speechless!

[@ChristopherRoss.]

28:23 With those "weaker" notes, I noticed that the fundamental is also weaker. To me (I'm a mixing engineer, so I encounter this in my day to day often enough) that indicates--and I'm also hearing--phase cancellation. It's not that she's failing to produce the notes, its that she's doing it so well that the sounds are actually cancelling each other out.

[@byronsteele7855]

that harmonics will also stack at certain frequencies as the "overtones" will have their own overtones (in favourable conditions). So even overtones will naturally be louder than odd overtones.

[@theblacksheep00]

Screaming is a form of adding overtones to “original notes” in a way as well so!😀😊

[@Gleesonglee]

If I ever wanted to have some fun with a sound mixer I would produce overtones. They initially thought it was some kind of feedback and then they couldn't really hear what was happening.

[@sparkylinkline]

Interesting. I am sure it sounds much different to her than to the recording. I notice more differences in level here in Elizabeth's review video than in the original video. I do notice varying levels in the harmonic as it varies from the fundamental. Makes me wonder how far the mic is from her to produce the cancellation effect. Thx.

[@fabionoir]

I had the chance to work with her on stage as sound tech for a group she sings with (2 of the musicians of this group are friends of mine), seeing her at just 1 meter away from me was really incredible and is very difficult to explain. Simply amazing and hypnotic. Here is an example of the ensemble: kzbin.info/www/bejne/qWWle2ato8xpg80

[@Platypi007]

Ever since I first heard a Tuvan throat singer I have messed around with overtone singing from time to time, but I'm about where you are in that I can pick a fundamental and after working on it some can work out a melody with the overtones. My overtones aren't anywhere near as clear as hers, or other overtone singers I've heard. But hearing her control over both the movement of the fundamental and overtone blew my mind just like it did yours.

[@zaatar5913]

Yes yes. Lala. So impressive

[@fidrewe99]

What I find even more mind-blowing is, you can combine this with any kind of singing, since for every vowel at any pitch, the second formant can be tuned to a nearby overtone to amplify it. Yon can then compose lyrics in a way that they create nice overtone harmonies. It's not going to be as loud as in this video, but still audible. This is because in order to get it that loud, one needs to lower the 3rd formant to combine it with the 2nd one, which creates an overall "r"-like sound and sacrifice some of the higher resonances, i.e. the full and bright qualities of the voice. Without those sacrifices, an intense and well-tuned 2nd formant really makes the voice shine.

[@hehunches]

Genghis Blues is a 1999 American documentary film directed by Roko Belic. It centers on the journey of blind American singer Paul Pena to the isolated Russian Republic of Tuva to pursue his interest in Tuvan throat singing. Overtone singing should not be confused with throat singing, in spite of the fact that many throat singing techniques comprise overtone singing. As mentioned, overtone singing involves the careful manipulations of the vocal tract, whereas throat singing is mostly related to the voice source. Thanks for this.

[@visualdragon]

[@chirpycrow2061]

Actually it's a very simple technique. I've learned to pick up just by watching Anna Marie's video while moving my tongue around to find the clearest overtone pitch. I picked it up in a few months. Once you have established it, ya get hooked on doing it. I have a 5.33 octave range and some nodules, so I need to be careful! This style of singing is so mesmerizing and kinda brings ya into a meditative state! Amazing!

I'm looking forward to this!

[@mikeofmidgard]

Wow! How cool is that? And seeing in the spectrogram the absolutely clear harmonics is amazing!! I'm really curious for this one. And it's clear - you need to convince her to let you have look inside her throat when creating these polyphonic sounds 🧐 😉

[@YnEoS10]

I’m pretty sure this technique is done with the shape of the mouth, creating resonances to amplify naturally occurring overtones in the voice until they stand out distinctly. Different shapes are used to amplify different overtones in the series. So no throat cam needed to analyze. (Will also did a bit of this technique with the throat camera, just with less control over the overtones.)

[@ulrichvonbek1618]

There is actually a video of her here on KZbin where she shows recordings of her mouth and throat while singing that were made in a lab. It's some kind of presentation - I'd have to look it up, but I think it should be easy to find. Edit: Here it is - kzbin.info/www/bejne/fIrGeKOvhqp8bq8 But someone already mentioned it in the comments here, too. I used to "recommend" her to fans of Pentatonix who commented on Avi Kaplan's overtone singing. :)

In my intro physics class, we discuss the frequency spectra produced by strings and pipes. I demonstrate overtones with a poor version of the type of polyphonic singing she does first. I'm very far from her ability, but you can see the "brightening" of the overtones in the frequency analyzing app I use.

Would LOVE to see this software on Shania Twain’s voice. For years I thought her vocals were just heavily processed, a studio trick by hubby/producer Mutt Lange. Then I forgot all about her for a long time. In the last year or two, I watched an interview with her and could hear all the overtone stuff I’d heard on records in her normal speaking voice. Truly a special case!

You're absolutely right. You really have to look at the spectrogram to understand what's actually happening. All I can hear is Mongolian throat singing, but I can't really appreciate even half of what's going on. The visualization makes everything super clear, so thanks for that.

[@ircubic]

Stich or SHOW-GO would be amazing. I feel like SHOW-GO's stuff would be a better starting point for this channel, since he makes "actual songs". Stich makes songs too, but they still feel a bit less cohesive, more like technique showcases than "proper songs". D-Low is a necessity if the aim is just to check out insane technique (30 basses is a nice showcase)

[@thierryflaven4160]

Thanks, I had fun to sing for the first time overtone for the last 5 days with a lot of questions. Questions mostly because I saw Anna-maria video and I have a lot of doubt about the power of her overtones compare to mine. I found and used 'friture' free software on my PC at the same time that watching your great video. I checked if I got the same spectrogram than you and then check with my own voice doing overtone to see if I was really making it... (Ya about a half power of my fundamental) Hahaha That is so great, I'm pretty good but as a beginner it's hard to ear my own overtone and maintain them so that I can realize they are there and could work the resonance to gain power. Eventually in few hour from you video, I was able to gain power on my overtone (same level than the fundamental so far for me, but not consistent at all; and I'm still so impress by some of her which are higher than the bass). And bonus I made a first modulation of my overtone without to move the fundamental, I was able to repeat and loop on then. I don't know much about music but visualisation/tool with your explanation made it happens. Thanks again!

[@rbrohammer]

I love the little hop at 3:01!

[@fluiditynz]

I like how she also modulates the beat frequency.

[@josephknurek7795]

[@808musicman808]

Ive seen Anna’s idea before and am truly amazed! I have been practicing polyphonic overtones singing for 3 weeks now. I’ve gotten good enough where I’m able to distinguish sometimes 5-7 overtones per fundamental tone. Im nowhere near Anna with how clean her voice is and how talented she is. I giggle when I’m able to hit the overtone really well. I notice depending on which note I’m singing for a certain fundamental tone, the overtone is a lot stronger. Than other notes. I’ve performed in a band and have been singing for over 3 decades. I was so stoked to discover this and couldn’t believe this was even possible. I love learning this technique and can only hope to achieve what Anna is doing! Love what you’re doing using the spectrogram to visually see what’s happening. Was wondering if you know or have seen this person who seems to be the only one achieving these super base sub frequencies that I’ve found, and would be interested to see this video analyzed on your program. Here’s a link to a video I’ve found of this guy. He’s taking polyphonic overtones to another level! kzbin.infoWutlSRzrKiI?si=D2pFQzdx2G56v_4e

Liz, I f....ing love you and the way you can express the physical and biological inner workings of a voice. It erases all frustration I ever felt trying to describe a composition or performance

[@oraculox]

And on another note, isn´t it a property of sound to resonate stronger with less effort on higher frecuencies?. Whales rely on really high frequencies to communicate longest distances because of the nature of the medium. I think that goes for any kind of wave, the light of the tiniest stars reach us in the higher frecuencies, but a very large star only reach us on the lowet frequencies.

[@fluiditynz]

That is so bizzare. I think it's been something I've been able to do for a long time but I never identified it as throat singing until now. I was mucking around (still)trying to develop the kagura rumble and then experimenting adding things I do know. Anna-Maria is just so much better at it though!

If you watch her videos she gives recommendations for other amazing overtone singers and a history of throat singing in general. While she is exceptional there are others who aren't as well known or don't stand out because it seems more expected of them culturally to be able to do it (such as Mongolian or Tuvan). Overtone singing in general isn't that exceptional, even I can do it, it's her control of what she calls polyphonic singing (controlling the overtone and fundamental independently in a musical way) that is impressive. I only watched a quarter of this because I've already seen this type of analysis on Anne-Marie's channel - although it's nice that this channel is sharing it with more people.

[@Bobbias]

Yeah, once you get a feeling for what the overtones sound like, you can hear them all over the place. What's interesting is that the balance between the different overtones (that is, how loud they are, both compared to the fundamental, and each other) make up the timber of an instrument/voice. The difference between piano, guitar, violin, and marimba basically just comes down to what overtones are produced along with the fundamental, and how loud they all are.

Wow this was amazing, and seeing you nerd out with such passion and knowledge was terrific. It really helps having the software to visualize it too, as clearly identifying the overtone and fundamental can be difficult at points if you’re not used to hearing polyphonic singing. If you want to hear more polyphonic singing in music, you should check out Epta Astera. They combine folk metal with Gregorian chants and polyphonic singing, it’s amazing stuff.

[@manahaas]

[@Zyroburnz1237]

BRAVO! If MUSIC is the universal language - as I believe it is - than you're the UNIVERSAL INTERPRETER!

[@kamaradski1]

That was great thanks! Could you also do one for "Yma Sumac"? I'm really curious about the voice science for that one :)

Whoa, I remember this video. So cool to hear it analyzed!

Check out Ghengis Blues for a documentary of a blues singer who performs Tuvan throat singing. Another to check out is the music of The Suitcase Junket. Also polyphonic singing in his one man band blues.

Avid Kaplan once did a live performance doing lion sleeps tonight in overtones. I was blown away. Its not the best recording but fun to see

Honey, I have been around classical music for better than 7 decades and in audio work for 4 (live sound mixer), and have never even heard of this before, let alone heard it. Harmonics (overtones) yes of course. But not nearly to this extreme. However, you indicated this is far from unique, there are cultures that practice this. BTW, My RTA shows the fundamentals and the 'overtone' clearly but also some other harmonics that are not nearly as audible. (Like you, I pull out some gear or software to help visualize) Fantastic work. I came across her first, then your review. Thank you very very much. Youn are awesome. Buster
