Decoded: The Hidden Melody in Syllables!

Imagine you could hear a melody that remains inaudible to most people – an acoustic illusion that challenges your senses and revolutionizes your understanding of sound. This is exactly what happens in my viral listening test that fascinates people worldwide.
In my new video, I dive deep into the science of sound with VoceVista and reveal the fascinating acoustic mechanisms behind this exciting listening experience. What to expect:

  • A detailed spectrum analysis that reveals the hidden structures of sound
  • A dynamic spectrogram that reveals the journey of your sound perception
  • Insights into the neuronal processes that determine how our brain decodes melodies
  • The scientific solution to the riddle: How do we perceive melodies that don’t seem to exist?

Let yourself be enchanted by the wonders of acoustics and expand your perception of sound. This insight will change your listening habits forever!

Calculating the Harmonic Series – a New Tool for Musicians, Singers and Acoustic Enthusiasts

Recently, in one of my 432 Hz discussions, it would have been helpful to have the tone names and frequencies of the overtones to hand. The

So I programmed myself a suitable tool (with AI help) that I find super practical. The new tool is now available on my special page, with which you can calculate the first 32 partials of a tone – in a matter of seconds!

The special thing about it:

  • Freely selectable concert pitch frequency: perfect for historically informed music, experimental tunings or individual applications.
  • Notation in both systems: The results appear in both German and American notation.
  • Exact frequencies and cent deviations: Recognize the differences to equal temperament immediately.

The tool is flexible and intuitive: you can enter either the frequency (e.g. 432 Hz) or the note name (e.g. “E”) as the keynote. The compact table then shows you all the relevant details.

There is also a second tool that allows you to calculate intervals between any frequency pairs in cents. Together, these two tools make analysis and comparisons incredibly fast and precise – ideal for singers, composers, choir directors and sound researchers!

I use the tool myself to quickly determine tone names and frequencies in relation to changing concert pitch frequencies. What used to involve a lot of manual calculation or copying from VoceVista is now done by this tool in just a few clicks.

Try it out.

PS: Let me know what creative ideas or applications you come up with using this tool!

Wolfgang Saus Lecture (German): Overtones – Discover the Magic of Your Voice!

Overtones – Discover the Magic of Your Voice

A lecture on the effect of overtones at the Symposium Music Resonance 2024 in Bad Zwesten: Discover the magic of your voice – Experience fascinating sounds, calm your mind and create unique worlds of sound.

This lecture is currently going a bit viral, with 10,000 views in just two weeks, which makes me very happy. Because I think the content is absolutely worth spreading – of course, otherwise I wouldn’t be giving it. I truly believe that with the voice and enhanced listening you can change consciousness and the world and create the new world we wish for.

Quotes from the comments:

“It’s 0:40 and I can’t interrupt this.”

“I don’t think I’ve ever met anyone who has such a multispectral intelligence. You share something, you have something to say.”

“YouTube suggested a real gem of a video to me; I’m flashed; it’s totally fascinating.”

“I had so much planned for today. I listened to the lecture instead. So incredibly good.”

Of Overtones and Love Messages: How a Video Redefines the Boundaries of Vocal Control

In a universe where Valentine’s Day, Ash Wednesday and World Sound Healing Day magically come together, a fascinating video reveals the hidden world of vocal sounds: a spectrogram of curious vibrations that look like letters and form the words “I LOVE YOU”. But what exactly is behind this amazing phenomenon?

Welcome to the world of the secret language of overtones, a realm that only a few have explored. As the author of this blog, I have probably mastered one of the most precise controls of human vocal resonance on the planet. Because let’s be honest, who else but me could accomplish something so masterful? (Of course, you are welcome to prove me wrong at this point. And I would be very happy if you did. Just give it a try!)

The voice, a miracle of nature, harbours more secrets than most people can imagine. Did you know that the true essence of the voice lies in the resonances of the vocal tract?

Yes, the overtone chord may seem like the star of the stage, but the real magic lies in the resonances that make our voices unique. This is just the beginning of an exciting journey I want to take you on. Are you ready to push the boundaries of controlling your voice? Then subscribe to my newsletter so you never miss a post. Because there is still a lot to discover in the world of vocal resonance.

Do You Hear a Melody or Syllables? Saus’ Hearing Test.

In this video you will learn how to hear harmonics in vowels. This will open up a new dimension of sound perception to you. This way of hearing is rare on the fly, but it can be learned and is a prerequisite for understanding and learning choral phonetics. And it makes learning overtone singing easy and fast.

Do You Hear Syllables or a Melody?

After this video, your hearing is immediately changed, and that irreversibly. It is like a picture puzzle: once you have seen both sides, you will always see them. After the video, you are always able to hear harmonics in sounds. As soon as you have perceived both syllables and overtones, you can decide what you want to hear. And if you focus on harmonics for the next 3 weeks from today, your overtone hearing will become an integral part of your sound perception. Your brain will form new synapses.

Side Effects

You’ll be surprised what additional changes come after that:

  • You will hear more empathically, understand better how other people feel, just by hearing their voice.
  • When you sing in a choir, you will perceive intonation quite differently and unconsciously find a resonance with other voices.
  • Many also report that they perceive colors and scents more intensely afterwards.
  • You will notice a more conscious access to resonance in your voice.

If you immediately heard the melody in the first example, then you already were an overtone listener. Then the video will help you understand and become aware that you hear differently than 95% of the people around you.

But I Never Sang a Melody

One of the most exciting things about overtone listening for me is: In the end, everyone has heard the melody once, right? – but I never sang a melody! In all the singing examples, all the pitch frequencies are unchanged. I have not changed a single pitch. So in the classical sense I did not sing a melody. I only changed resonances and thus volume ratios, so in the classical sense I sang syllables on a single note, which is what most people heard at the beginning.

Despite Contradiction Everybody is Right

So if someone thought at the beginning that there was no melody, he was right, even when the melody became obvious to everyone. And everyone who hears a melody is also right. One would have to define melody independently of the tone pitch.

Many years ago, after I found out that others do not hear the same as I do, I had sent a sound file of the first example to various experts. But nobody found a melody, not even with the most modern methods of analysis. Why not? Because apparently no one thought to look for a melody. However, after hearing the melody, one finds it in the sound spectrum. But only as a volume pattern, not as a pitch change. Isn’t that exciting?

Personally, I have learned from this to approach perceptions of other people with less prejudice, especially people from the spiritual realm, who I might have dismissed as unscientific in the past. Leaving paradigms behind is probably part of the coming zeitgeist in many ways.

Video Transcription

The most important thing in overtone singing is listening. It turns out that not everyone hears the overtones spontaneously. These are studies from the early 2000s in Heidelberg at the University Clinic, which showed that it depends on which part of the brain processes the sound. There is an auditory center on the right side that hears harmonics, and there is an auditory center on the left side that is responsible for the mathematical part of music, that is, intervals and melodies and rhythm and things like that. On the right hemisphere the timbre is analyzed, but that also includes the information of the overtones, which are usually not heard separately. And then there is an interpretation of sound as language. That happens on the left side in the Broca and Wernicke centers, which are both located on the left side. And now it’s important that when you sing overtones, that you hear the overtones. That means that you have to activate the right side, the right auditory cortex. For that, I have a test that you can use first to check where you stand, and at the end, there’s a systematic guide to the perception on the right hemisphere. So when this video is over, you’ll hear completely differently if you don’t already heared the overtones right from the first example. Now I’ll sing a meaningless sequence of syllables, and I’ll sing them on a single note, that means I won’t change any pitch, yet there’s a melody in these syllables, and I’ll hide this melody in the resonances of the vowels. Let’s see if you can hear that.

So, that was a very well-known melody from the classical period. As a little hint: It was composed in Bonn and I don’t want to hide it at all. The point is to learn to listen to it, it’s not about showing now what you can’t do, but just the opposite. It was “Joy, Beautiful Sparks of the Gods” in this register.

Typically, only 5% of people hear this melody spontaneously. If you now know what to listen for, you may now already have a little inkling of the melody or even hear it clearly. For those who don’t hear the melody now, this has nothing to do with musicality, but only with the preference on which side your brain processes this sound. There is usually a block when the left brain decides that this is speech, but it doesn’t understand a word. Then it tells the rest of the brain: Shut up, I need all the attention. And language is very dominant in our brain. That’s why this side, here the speech center, is apparently particularly active in most people. But now I would like to change this filter that says important and unimportant, language is important, timbre and overtones are unimportant. I would like to turn that around. And I do that by systematically removing information in the sound for the left side, for the speech center. I do this step by step in such a way that you will recognize at which point this flips over. At the end, you will definitely hear the melody.

Now I’ve only used Ü sounds like that, and that means in the phonetic vowel triangle I’ve only gone along vowels where the second formant, as they used to call it, or I call it “second resonant frequency”, changes. I left out all the frequencies that move in the direction of the vowel A, that would change the first resonance. So now usually there’s about 20% of the people who perceive the melody now. For the rest, I go one step further and leave out the consonants. Now usually about 40 to 60 % of the people are with me and hear this melody. If you don’t hear it yet, I go one step further.

Now everyone should have heard the melody. Who now does not hear the melody, as a whistling melody, then I unfortunately can not help. But I have never experienced that someone has not heard the melody. It can only be that one hears in such a way that it does not belong to the voice. Most people hear it as a whistling melody. And there it is separated in the brain, one then hears two separate melodies, respectively one hears a humming tone and in addition a whistling melody. For some people, this whistling melody can no longer be assigned to the voice, while others can associate this whistling tone with the voice. The main thing is that you hear this melody now.

If it has disappeared now, go back to that example where the consonants weren’t there yet, or where the consonant was N. I can fine-tune that again by replacing the T-sound with a D-sound. You’ll notices here, the more sibilants are added, the more this melody now moves into the background of awareness, and the speech center pushes itself into the foreground. But the melody is still there. Particularly interesting is the transition where you’re no longer sure, is it just my imagination, because I know what I’m supposed to hear, or did I actually hear that? And that’s a very interesting transition, because that’s where the conscious mind decides whether it trusts the right hemisphere of the brain. It’s a trust thing. You know that I’m singing the melody, so you can trust me. If you don’t trust me, then trust your own perception. If you mistrust it, then yes, you don’t know. But still the melody is there. I know that I am singing it. Next step.

Now I have added a little bit of movement into the first resonance again. And now I take a little bit more movement into it, and then I’m back at the beginning, which I started with.

And I hope that now most of you have come along up to that point. But if you have lost the melody two or three examples earlyer then it’s still perfect, then the right hemisphere is now activated. And this is an essential foundation to learn to sing harmonics.

Note: Video and link currently only work from Germany.


Surgeon Gabriel Weston has spent many years studying the functioning of the human body. In the series «Incredible Medicine: Dr Weston’s Casebook» she presents people from all over the world with the most unusual bodies and abilities.

One of them is the unique body control required for overtone singing (from 10:40 min.). In November 2016, a film team from BBC Science Production, Emma Hatherley (production, direction) and Alexis Smith (camera), produced a film at the Institute of Music Medicine at the University Hospital of Freiburg with Prof. Bernhard Richter and Wolfgang Saus.

Live images from the magnetic resonance tomograph show the complex motion sequences in the mouth and throat that are involved in overtone singing. Interviews explain the scientific background of the phenomenon.

Do You Hear a Melody? – Take the Listening Test

In just 3:20 minutes, this listening test opens your ears to a new dimension of hearing that only around 5% of musicians are aware of: overtone hearing. This ability is essential for learning overtone singing. And it is a prerequisite for the practical implementation of vocal and choral phonetics.


New Videos

 


In 2004, a research group led by Dr. Peter Schneider at Heidelberg University Hospital discovered that people perceive sounds differently depending on which hemisphere of the brain processes them. They developed the Heidelberg Hearing Test to determine whether someone perceives fundamental tones or overtones more prominently in a sound. →Take the Heidelberg Test here

My hearing test is different. It evaluates whether someone recognizes vowels or overtones more strongly in a sound. In the second part, it trains the ability to shift the perception threshold from vowels to favour overtones.

→Watch a video about the background.

Saus’s Listening Test

Relax and listen to the first sound sample. I sing a sequence of nonsensical syllables on a single pitch. If you recognize a familiar classical melody within it, congratulations! You have exceptional overtone hearing and belong to the 5% of people who can perceive this spontaneously.

Audio Example 1

Download mp3

If you don’t hear the melody, don’t worry. By the end of the listening test, you will hear the overtones.

In the next audio examples, I gradually remove more and more sound information from the voice that the brain interprets as part of speech. Next, I will sing the syllables by changing only the second vowel formant while keeping the first one steady in a low position. The syllables will then only contain Ü-sounds [Y], making the melody clearer to some listeners.

Audio Example 2

Download mp3

If the melody is now becoming clear, congratulations! At this stage, 20-30% of people can hear the melody. Perhaps you only suspect the melody but aren’t sure if you’re imagining it. Trust your imagination. Your hearing picks up the melody; it’s just that a filter in your consciousness tells you the information is not important. Speech recognition is much more important.

At this point, I’ll reveal the melody: It’s “Ode to Joy” from the 9th Symphony by Ludwig van Beethoven. In the next audio example, I’ll whistle it tonelessly. This will help your brain learn what to listen for. Afterward, listen to Audio Example 2 again.

Audio Example 3

Download mp3

Is it clearer now? If not, listen to the next example.

In Audio Example 4, I remove the consonants. At this point, the Broca’s area, the brain region responsible for speech recognition, has nothing to do and transfers auditory attention to other regions.

Audio Example 4

Download mp3

Now, about 60-80% of listeners can hear the melody. If you still can’t hear it, you are likely classified as a fundamental tone listener in the Heidelberg Hearing Test. This has nothing to do with musicality. You are in the company of some of the best flutists, percussionists, and pianists.

In the next example, I completely modify the sound. By using a specific tongue position, I lower the third formant by two octaves until it matches the frequency of the second formant. This creates a double resonance that does not occur in the German language.

Audio Example 5

Download mp3

This technique is called overtone singing. The ear now lacks familiar sound information, and individual partial tones become so loud due to the double resonance that the brain separates the sounds and informs your consciousness that it perceives two tones.

You likely hear a flute-like melody alongside the voice. Overtone singing is an acoustic illusion. In reality, you’re hearing more than 70 partial tones. Physical reality and perception rarely align.

In the final audio example, I go backward through the entire process to the beginning. Try to keep your focus on the melody the entire time. Feel free to listen to Audio Example 6 multiple times; it trains overtone listening and improves your ability to perceive sound details with confidence.

Our reality is created within ourselves. And it is changeable.

Surgeon Gabriel Weston has spent many years studying the functioning of the human body. In the series «Incredible Medicine: Dr Weston’s Casebook» she presents people from all over the world with the most unusual bodies and abilities.

One of them is the unique body control required for overtone singing (from 10:40 min.). In November 2016, a film team from BBC Science Production, Emma Hatherley (production, direction) and Alexis Smith (camera), produced a film at the Institute of Music Medicine at the University Hospital of Freiburg with Prof. Bernhard Richter and Wolfgang Saus.

Live images from the magnetic resonance tomograph show the complex motion sequences in the mouth and throat that are involved in overtone singing. Interviews explain the scientific background of the phenomenon.

Do You Hear a Melody? – Take the Listening Test

In just 3:20 minutes, this listening test opens your ears to a new dimension of hearing that only around 5% of musicians are aware of: overtone hearing. This ability is essential for learning overtone singing. And it is a prerequisite for the practical implementation of vocal and choral phonetics.

In 2004, a research group led by Dr. Peter Schneider at Heidelberg University Hospital discovered that people perceive sounds differently depending on which hemisphere of the brain processes them. They developed the Heidelberg Hearing Test to determine whether someone perceives fundamental tones or overtones more prominently in a sound. →Take the Heidelberg Test here

My hearing test is different. It evaluates whether someone recognizes vowels or overtones more strongly in a sound. In the second part, it trains the ability to shift the perception threshold from vowels to favour overtones.

Saus’s Listening Test

Relax and listen to the first sound sample. I sing a sequence of nonsensical syllables on a single pitch. If you recognize a familiar classical melody within it, congratulations! You have exceptional overtone hearing and belong to the 5% of people who can perceive this spontaneously.

If you don’t hear the melody, don’t worry. By the end of the listening test, you will hear the overtones.

In the next audio examples, I gradually remove more and more sound information from the voice that the brain interprets as part of speech. Next, I will sing the syllables by changing only the second vowel formant while keeping the first one steady in a low position. The syllables will then only contain Ü-sounds [Y], making the melody clearer to some listeners.

If the melody is now becoming clear, congratulations! At this stage, 20-30% of people can hear the melody. Perhaps you only suspect the melody but aren’t sure if you’re imagining it. Trust your imagination. Your hearing picks up the melody; it’s just that a filter in your consciousness tells you the information is not important. Speech recognition is much more important.

At this point, I’ll reveal the melody: It’s “Ode to Joy” from the 9th Symphony by Ludwig van Beethoven. In the next audio example, I’ll whistle it tonelessly. This will help your brain learn what to listen for. Afterward, listen to Audio Example 2 again.

Is it clearer now? If not, listen to the next example.

In Audio Example 4, I remove the consonants. At this point, the Broca’s area, the brain region responsible for speech recognition, has nothing to do and transfers auditory attention to other regions.

Now, about 60-80% of listeners can hear the melody. If you still can’t hear it, you are likely classified as a fundamental tone listener in the Heidelberg Hearing Test. This has nothing to do with musicality. You are in the company of some of the best flutists, percussionists, and pianists.

In the next example, I completely modify the sound. By using a specific tongue position, I lower the third formant by two octaves until it matches the frequency of the second formant. This creates a double resonance that does not occur in the German language.

Audio Example 5

This technique is called overtone singing. The ear now lacks familiar sound information, and individual partial tones become so loud due to the double resonance that the brain separates the sounds and informs your consciousness that it perceives two tones.

You likely hear a flute-like melody alongside the voice. Overtone singing is an acoustic illusion. In reality, you’re hearing more than 70 partial tones. Physical reality and perception rarely align.

In the final audio example, I go backward through the entire process to the beginning. Try to keep your focus on the melody the entire time. Feel free to listen to Audio Example 6 multiple times; it trains overtone listening and improves your ability to perceive sound details with confidence.

Our reality is created within ourselves. And it is changeable.

 

Test Your Rhythm Feeling

On ConcertHotels you will find a test that measures your precision of rhythm feeling. Take the test first. Then try singing overtones while you’re doing the test and write your results in the comment below if you like. I look forward to it.

Overtones are usually sung slowly and meditatively, rarely fast and rhythmically (there are exceptions). Overtone singers process sound more in the right hemisphere, drummers more in the left, says Dr. Schneider from Heidelberg University Hospital. Test here how your brain processes sounds.

Is that one of the reasons? An interesting question that has not yet been examined. I suspect that focusing on overtones, at least for the untrained, draws attention away from rhythm.

In my advanced courses, I experience that at first the intonation and sound quality of the keynote suffers when the focus goes entirely to the overtones. Conversely, concentrating on the keynote causes a poorer overtone quality or even complete loss of control of overtone singing. I can immediately recognize from the sound what a student is concentrating on.

If you want to sing polyphonic overtones, i. e. a fundamental melody and an independent overtone melody at the same time, then both tones must receive equal attention. I have developed special exercises for this purpose, which improve the clean control of both notes after a few hours. It would be interesting to examine whether these exercises have an effect on the feeling of rhythm. I will do the rhythm test in my courses as a before-and-after comparison. I’m curious to see what happens.

What are your experiences with rhythm and overtones?

 

Spectacular MRI Video of the Tongue while Singing Overtones

“Ode to Joy”, overtone singing by Wolfgang Saus inside an MRI.

This spectacular dynamic MRI video shows how the tongue moves during overtone singing. The melody of Beethoven’s “Ode to Joy” is created by double resonances which are shaped by the tongue in the mouth and throat. Overtone singing is based on the combination of the second and third resonance frequencies of the vocal tract on a single frequency to increase the volume of a single overtone from the vocal sound.

The second resonance frequency is controlled by the base of the tongue along with the epiglottis. The third resonance frequency is regulated by the space under the tongue, which is larger than it appears in the video, because it also spreads to the side of the tongue frenulum, which covers the space in the image. Overtone singing requires constant fine tuning of the two resonance chambers.

It is not easy to sing in the very loud magnetic resonance tomograph and even record the sound. The noise level is so high that I had to wear hearing protection and couldn’t hear my own overtones. I had to sing by feeling. That the right melody came out is spectacular in itself. It shows that it is possible to develop a body feeling for the exact pitch of the resonances that also works without acoustic control through the ear.

The team in Freiburg has developed highly specialized equipment for recording and filtering. Of course the sound is not HiFi.
