The Subtle Power of Resonance

From Noise to Deep Listening

This text is based on my talk at TEDx Perugia 2026, held at Teatro Pavone: a reflection on sound, resonance, and the possibility of rediscovering harmony in a world increasingly saturated with noise.

For many years, I have explored sound as an artist, harpist, researcher, and therapist. For me, sound is not only an acoustic phenomenon, nor simply a musical material. It is a path of knowledge. A threshold through which we can observe the body, the mind, emotions, relationships, and the way we inhabit the world.

In this sense, the harp is a great teacher.

When a string vibrates, sound does not arise from the string alone. It needs a resonating body, a space that receives that vibration, amplifies it, gives it substance, and allows it to expand. Without resonance, vibration would remain subtle, almost imperceptible. Through resonance, it takes form, becomes presence, and reaches those who listen.

The theatre itself is built upon this principle. For millennia, theatrical spaces have been designed to allow a voice, a gesture, or a sound to travel without being forced. And yet today, this no longer seems to be enough. We amplify everything: the voice, the image, the message, the presence. We live in an age in which everything can become louder, more visible, more immediate.

But precisely because of this, an essential question arises: are we still able to listen to what is subtle?

Are we still able to lean our ear toward something that does not shout?

We live immersed in a continuous soundscape. Traffic, engines, sirens, notifications, background music, voices, messages, images, content. Everything overlaps. Everything demands attention. It is not a harmonious landscape, but an incessant layering.

Little by little, we get used to it. We no longer notice this constant background, this continuous tension, this saturation. But the body registers it. The nervous system absorbs it. Our sensitivity changes.

Because noise is not only acoustic.

There is also perceptual, cognitive, and emotional noise. We are crossed by a constant flow of demands, information, urgencies, and stimuli. Everything calls us, everything interrupts us, everything seems to require an immediate response.

When everything is too full, the spontaneous reaction is to increase the volume. To be heard, we raise our voice. To attract attention, we intensify the message. To avoid disappearing, we accelerate. To emerge, we push.

But this strategy has a limit.

The more we increase the volume, the more tired we become. The more we try to emerge from the noise, the more we enter into competition with other sounds, other voices, other stimuli. At a certain point, we no longer truly listen: we react. We no longer choose: we respond automatically. We are no longer present: we are overloaded.

Perhaps part of our contemporary exhaustion arises precisely from this: from living constantly in a form of forced resonance.

Forced resonance is a resonance maintained by continuous external energy. Something vibrates because it is pushed, stimulated, solicited from the outside. It is a vibration that depends on pressure.

How often do we live like this?

We move because we are solicited. We produce because we have to respond. We speak because we need to be noticed. We activate ourselves because something outside us is constantly demanding energy.

But a vibration maintained only by force wears itself out. It requires more and more energy. And when the energy is lacking, the system stiffens, empties, or shuts down.

Yet there is another form of resonance. More subtle. More natural. More powerful.

It is called sympathetic resonance.

In acoustic physics, sympathetic resonance is the phenomenon through which a vibrating body can set another body into vibration, when the latter is tuned to the same frequency or to a compatible one. There is no need to touch it. There is no need to force it. The vibration travels through space and finds a response.

Anyone familiar with the harp or the piano knows this well: when one string vibrates, another string can begin to vibrate on its own, simply because it is in relationship with that frequency.

For me, this is one of the most beautiful phenomena of sound.

It is not imposition. It is encounter.It is not effort. It is correspondence.It is not power over the other. It is the capacity to enter into relationship.

Sympathetic resonance teaches us that not everything that transforms needs to be loud. Not everything that acts needs to impose itself. Sometimes, what is deepest operates subtly: it creates the conditions for something to respond from within.

We can also experience this in the body.

When we emit a simple sound, a vowel, a hum, or a closed-mouth tone, not all frequencies produce the same sensation. Some vibrate more in the throat, others in the chest, others in the skull or the face. Sometimes, by slightly changing the pitch, we feel that something settles more naturally. The body responds. The voice stabilizes. The vibration finds a path.

In that moment, we have not used more force. We have listened more deeply.

When we find a frequency of resonance, less energy is required, not more. The voice does not tire because it is not pushed: it is tuned. The sound does not need to be forced: it finds its passage. The vibration is not imposed: it is activated.

This process teaches us something essential.

First comes silence. Without an empty space, we cannot perceive what is happening.Then comes listening. Not only with the ears, but with the whole body.Then comes tuning: small adjustments, almost imperceptible, until we find the point where something responds.Finally comes activation: the vibration spreads, takes body, and generates presence.

This principle lies at the heart of many practices related to sound: sound therapy, vibroacoustics, music therapy, and the therapeutic use of voice and instruments. Of course, this does not mean considering sound as a magical solution for everything. But sound can act deeply on the body, the breath, the nervous system, attention, and emotional states.

The body is not only a biological machine. It is also a sensitive, rhythmic, vibrating system.

The heartbeat, the breath, the voice, the step, brain waves, gestures: everything in us participates in a great rhythmic organization. When this organization is disturbed, we feel fragmented, tense, scattered. When something becomes tuned, we rediscover a feeling of unity.

And this does not concern only the body.

It also concerns our life.

Each of us knows intuitively the difference between what consumes us and what makes us vibrate. There are activities that drain us, even when they seem important. There are relationships that make us rigid. There are environments in which we lose energy. There are words that extinguish us.

And then there are situations in which, almost suddenly, something aligns. An activity, a person, a place, an idea, a direction. We feel more presence, more clarity, more enthusiasm. Effort does not disappear, but its quality changes. It is no longer dispersion. It becomes movement.

This is a form of resonance.

When we are in resonance with what we do, our energy is no longer fragmented. It becomes coherent.

Alignment, coherence, harmony.

These words are not merely poetic. They describe a very concrete state. To be aligned means that what we think, what we feel, and what we do are not moving in opposite directions. To be coherent means not dispersing our strength into a thousand contradictory frequencies. To be in harmony does not mean being always calm or perfect. It means being able to inhabit complexity without losing our centre.

Like a harp string.

A string that is too tense risks breaking. A string that is too loose does not sound. But when it is tuned, it can vibrate fully.

Perhaps we spend our lives searching for this tuning: between what we are and what we do, between what we desire and what we offer, between our inner rhythm and the rhythm of the world.

And when this tuning happens, the way we relate to others also changes.

When I am internally dissonant, I often try to be heard by increasing the volume. I try to convince, to occupy space, to impose my rhythm. But when I am more tuned, I can do something different: I can listen.

I can ask myself: what makes the other person vibrate? What is their rhythm? Which word opens a response? Which tone creates presence rather than defence?

We see this in music. Two musicians playing together do not simply need to play loudly. They need to listen to each other. They need to breathe together, perceive intentions, anticipate gestures, leave space. Beauty does not arise when one dominates the other, but when differences find a common form.

This is also true in relationships.

Synchronization lies at the foundation of empathy. It does not mean becoming the same. It does not mean dissolving oneself into the other. It means creating a shared field in which something can circulate. A field in which I remain myself, you remain yourself, but between us a shared vibration is born.

Perhaps this is what we need today.

Not more noise.Not more intensity.But more tuning.

If we widen our perspective, we discover that this intuition does not belong only to music or therapy. It is an ancient vision of the world.

The Stoics spoke of sympatheia: a deep connection between all parts of the cosmos. For them, the universe was not a sum of separate elements, but a great living organism, crossed by a common principle. Every part was in relationship with the whole. Every gesture, every movement, every transformation had a resonance within the whole.

This word, sympatheia, is very close to sympathetic resonance.

It reminds us that we are not closed systems. We are not isolated individuals vibrating in a void. We are constantly influenced by what we listen to, by the places we inhabit, by the people we spend time with, by the ideas we nourish, by the words we repeat.

And at the same time, we too influence the field around us.

Every word has a tone.Every gesture has a quality.Every presence leaves an imprint.

We can imagine ourselves as strings of a great harp. Some close, some distant. Some low, some high. Some tense, some fragile, others still silent. But none is completely separate from the others.

When one string vibrates, something can respond.

And so the question becomes very concrete:

What am I entering into resonance with?With which noises am I feeding my attention?With which words am I tuning my mind?With which people, places, images, and thoughts am I vibrating every day?And above all: what do I make resonate in others?

Because we can generate noise. We can generate tension. We can generate dissonance.

But we can also generate space.We can generate listening.We can generate trust.

We can create that subtle quality through which the other does not feel invaded, but recognized. Not pushed, but called. Not forced to react, but invited to respond.

Perhaps this is the deepest power of resonance: it does not constrain, but activates. It does not dominate, but sets in motion. It does not simply increase the volume, but reveals what was already ready to vibrate.

In his Letters to Lucilius, Seneca writes that this whole world, encompassing both the divine and the human spheres, forms a unity, and that we are members of one great body.

Perhaps today we can listen to these words not as an abstract idea, but as a practical invitation.

To learn to be silent.To learn to listen.To learn to tune ourselves.

To recognize our own frequency, without wanting to resonate with everything. To recognize the frequency of others, without wanting to cover it. And then to move together, not as voices in competition, but as parts of a greater composition.

A living composition, mobile, imperfect, but possible.

We do not need more noise.We do not need more force.We need to rediscover the point where life begins to vibrate again without being forced.

This is the subtle power of resonance.
