polyphonic overtone singing – explained visually


you [Music] hello I am Anna Maria and I’m an overtone singing and I’m going to tell you something about polyphonic singing today overtone singing is a voice technique where one person sings two notes at the same time [Music] oh the left side of the screen is a spectrogram a visual representation of my voice this is my normal singing voice when I’m singing a tune I’m really singing many tones at once the fundamental and the overtones they all sound at the same time and normally we hear them as one single tone using frequency filters in the computer I can listen to each over tune separately [Music] [Music] but I don’t need the computer to filter the overtones with overtone singing techniques I can filter them with my mouth my voice produces the same sound as before but now my mouth filters out all the overtones that I don’t want the one that remains is amplified and gets louder [Music] this is the basic idea of Overton singing I simply make one of the overtones so loud that you can hear it as a separate tone so this was the Overtoun scale on one fundamental I can also choose an overtone and move the fundamental [Music] moving the fundamental is more advanced than moving the Overtoun on one fundamental to understand this better consider the undertone scale of this stone [Music] each of those terms is a fundamental who has the original tone as one of its overtones so I can choose a fundamental and have the Overtoun scale or I choose the Nova tune and have the undertone scale and for polyphonic singing there are different possibilities to build scales and to move notes so I can move the overtone with the fundamental in parallel [Music] here the fundamental melody and the overtone melody are the same they are always the same interval apart in the second example I’m also moving the Overtoun with the fundamental in parallel but this time I’m using a different interval [Music] or I can move the fundamental in steps [Music] as you can see and here the fundamental jumps back and forth on these two tones which found the interval of a perfect fourth and the overtones from this melody [Music] now the fundamentals have a whole tone step [Music] now the fundamentals have a semitone step [Music] you I can also move the overtone and the fundamental in the opposite directions [Music] on that scale also makes a major [Music] and with these tools I can sing for example Fox songs in polyphonic [Music] in this example my overtones follow the melody of this Fox on the fundamentals are choosing to give me the overtones I need and to harmonize with the melody this is the overtone melody [Music] and this stability of the fundamentals now I’m using frequency filters in the computer again to show you what my overtones would sound like by themselves [Music] and these are the fundamentals by themselves [Music] and here are the two voices together if you listen carefully you can still hear the two voices separately thanks for watching if you’re interested in learning more about overtone singing or about my workshops and concerts please check out my website Anna – Maria – – calm the software I have used here is called overton analyzer it was specifically created as a learning tool for over ten singers if you want to see your own voice and practice some of my techniques you can find it at Overtoun analyzer calm

What an amazing video! I didn't knew that human vioce can do it! Thanks for share your work with the users! 😃👍

The 11th harmonic is barely ever used, because it's a quarter tone (quarter tone + perfect fourth + 3 octaves) relative to the fundamental, right?

This is unbelievably impressive! Just found your channel. Thank you for the wonderful content, and also for mentioning the software's name.

is it possible to do the major 3rd or 6th of the fundamental note in the overtone? would be awesome to harmonize your own voice

go to the intersection of rt66 and carlisle in america… the intersection; you cant walk around here and not find this structure…there is a hallway there; will make any melt. i have heard music in this place but to hear this, in that vortex of sound would be heavenly. think of a 50 ft hallway that also descends at a 45 degree angle… that is this hallway. it makes makes the best resonance… i dont think i can describe this adequately. im back on my throat chanting and resonance vids again. this "vault" of sound is awesome. find it. i told you ppl where it is. sing any song. you might cry…go to this place…

You are beautiful and so impressively talented. I really appreciate the amount of training and hard work it took to become so proficient at this skill. Absolutely fantastic. 😍😊

You can hear the polyphonic overtones in Lama Tashi's chanting. I think he's vocalizing more than two notes at once here but can't be sure. https://www.youtube.com/watch?v=rilzOlNHcys&t

Anna maria you're a very sweet person it's fascinating how u use your mouth to create a Helmholtz cavity and variating the geometrical volume and the opening of the mouth to get the different resonance is for me highly interesting. I love every thing that rotates/spins, swings/oscillates, vibrates/excites and shocks/pulses. Do you use ur nose as cavity to Theoretically you could induce a third pulsing pseudo tone if u manage to contract one of ur two vocal Cord's slightly u get two base tons instead of one but be aware it will tickle

Ada Jones (1873-1922) was a much better singer than you. I not like your voice sorry,but it got on my nerves as knives. I’m afraid I had been really shudder if I had hear the whole video

That's absolutely amazing!
Though I can't even sing a clear overtone melody even with one fundamental at the moment 🙁
But your videos are so cool!

while i was watching your introduction video on overtone singing i thought: "man, i wish i could watch her singing with a spectral analyzer!" and well, here it is! really well done, thank you.
and it is also nice seeing you having fun doing what you love.

Remarkable! – but what was your motive for the too low neckline? I tried to watch the keyboard but kept peeping right at your more remarkable cleavage. Perhaps a low neck line has some enhancing effect on the singing technique?

I found out that all old folk music tunes are from herding instruments playing the natural scale (harmonic series). So you can sing a complete folk tune (if it's old) while singing the same fundamental all the way through. Try Frere Jacques and the Farmer in the Dell which sit very low in the harmonic series.

So whenever I hear people speak, I’ve noticed that some people, despite having a higher voice, have a sort of deep tone that feels like it’s “filling in the bottom” is this at all related?

This is awesome! Just awesome!!! I'd love to hear you sing an actual song with this skill — I mean with lyrics and everything! Is that possible?

Ciao miss Anna. Volevo solo presentarti una persona che mi ha insegnato gli Armonici nel lontano 1995, e quindi cercare di capire cosa sono, il perche' hanno quest'effetto di benessere e come le vibrazioni, le scale, gli ipertoni, possono fondamentalmente cambiare positivamente l'esistenza di un essere umano…! Se vuoi vedere l'ultima performance di Andrea… Questo è il link: https://www.youtube.com/watch?v=uQxX1-g-EqQ&feature=share (Non amiamo essere in vista… Complimenti! Grazie e ciao miss Anna.

I'm pretty sure this is how this mermaid talks to whales and entices sailors to step off their boats and into the ocean to follow her to the depths below.

I just realised that whenever we sing a one note melody with words we are singing polyphonically. So we're always polyphonic singing, but most of us don't know which notes we are singing

This is my first time to hear and see it (throat singing) from white European women. I use to hear it only from native people from Russian North- mongoloidians from Tuvah, Khakassia, Buriatia etc'.

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!

нихуя не понял, но очень интересно) пойду лучше Тувинцев послушаю
