Overtone Voices

Listening to your resonances

Learn Overtone Singing
A Science-Based Approach

Your voice contains a hidden world of harmonics. Learning to hear them, before you try to sing them, changes the way you listen to everything.

I’m Iannis Psallidakos. I teach overtone singing through the lens of vocal acoustics: not tricks to memorize, but a real understanding of how your resonance works. Sometimes called throat singing or harmonic singing, overtone singing is the art of making the hidden frequencies in your voice audible as a distinct, whistling melody above a steady drone. When you know what’s happening inside your voice, the harmonics follow.

Private lessons via Zoom, from your first drone to controlled harmonic melodies. My approach is built on acoustic science and over a decade of teaching, but every session starts with listening to where your voice is right now.

Explore the science of the voice

Why does an overtone emerge? What makes a formant shift? How does the vocal tract shape sound? I’ve published research on these questions, and I explain them in a way that changes how you sing, not just how you think.

Sing in extraordinary spaces

Once a year, I lead a small retreat on the Greek island of Aegina, where we explore voice and resonance inside underground cisterns with astonishing acoustics, enclosed spaces where the reverberation is so vivid your voice seems to multiply. Seven people, four days, and a sound you won’t forget.

Who is this for?

Overtone singing isn’t reserved for ethnomusicologists or meditation teachers. If you’re curious about the hidden structure of sound, you belong here.

You might be a singer who wants to understand resonance at a deeper level. A voice teacher looking for acoustic tools to sharpen your pedagogy. A yoga or sound practitioner exploring the contemplative dimensions of voice. Or someone who heard overtone singing once, couldn’t stop thinking about it, and wants to learn.

Whatever brought you here, the approach is the same: listen first, understand why, then practice with precision.

What makes this different

Most overtone singing instruction falls into one of three camps. Some teachers focus purely on technique: copy these shapes with your mouth, repeat until it works. Others emphasize cultural authenticity: learn it the way the Mongols do, in the direct lineage of the tradition. And others wrap it in mysticism: sound healing, chakras, sacred vibrations.

Each of these approaches carries something real. But each one, on its own, misses something essential.

Technique without understanding is imitation. Cultural form without the perceptual state that created it is reproduction. And mysticism without acoustic grounding is wishful thinking.

My work starts somewhere else: with listening.

The herders who developed khoomei in Mongolia didn’t begin with vocal exercises. They began by listening, to wind across the steppe, to water in river bends, to the overtones already present in the sounds around them. The vocal technique emerged from a deep, sustained attention to the acoustic environment. The cultural form was born from a perceptual capacity.

That perceptual capacity is what I teach. Before you learn to produce an overtone, you learn to hear one, not as a vowel, but as a frequency. I use spectrograms to make your voice visible. I use spectrograms to make your voice visible. I draw on published acoustic research to explain what your vocal tract actually does when an overtone appears. And I ground everything in the practice of deep listening, learning to hear what’s already there before you try to produce anything new.

Because the first time you hear your own harmonic melody, knowing the physics doesn’t make it any less extraordinary. And knowing how to listen makes it possible.

“I completed a 12-session cycle with Iannis, what a result! He took me into unexplored areas of singing and adapted to my pace. Today I practice overtone singing daily with ease.” — Frédéric M.

“A masterclass on vowels and vocal acoustics that was truly fascinating. Iannis is a genuine enthusiast who conveys precise, technical tools brilliantly. I’d sign up again in a heartbeat.” — Myriam C.

“Iannis is always precise, committed to accuracy. His approach is as rigorous as it is original, and it raises the standard of voice teaching.” — Arnaud M.
