The Ancient Roots of Modern Sound Baths

I have studied Classics, and in my twenties worked as a field archaeologist and as a museum curator, spending long days with inscriptions and fragments of everyday objects. I loved reconstructing how these objects were once used and how they told stories of people, habits, rituals, and societal rules.

Although I have moved away from archaeology, the deep curiosity to understand where things and words come from, why and how are relevant today still entices me.

In my current work with yoga, somatic practices and sound baths, that same curiosity turns toward the historical roots of what we now call “sound baths.”

When we lie down in a room in London listening to bowls, gongs and chimes, we are also lying in a very long story: one that stretches from ancient Greek philosophers to medieval bell towers, from Himalayan bowls to Southeast Asian gongs.

This blog is an invitation into that story—through a few beautiful old texts, a touch of philosophy, and a simple look at how sound actually works in the body.

My wish is that, when you next come to a sound bath, you will feel that you are stepping into a practice that humans have used for centuries to soothe the nervous system, heal and rejoice.

Ancient Greece: Sound as Medicine for the Body and Soul

In ancient Greece, music was linked to health, ethics and the understanding of the universe. Pythagoras (570-490 BC), best known for maths and geometry, was one of the first to use sound as medicine, and to connect cosmic harmony (the Sound of the Spheres). Although his own writings are lost, later philosophers describe sound as a way to bring the physical and mental harmony.

Porphyry, a Neoplatonic philosopher (3rd–4th century BC) writes:

“[Pythagoras] healed psychic and bodily sufferings, with rhythm, songs, and incantations. He adapted these treatments to his companions, while he himself heard the harmony of everything because he could understand the unity of the spheres and the harmonies of the stars moving with them..”.

Another Neoplatonic philosopher, Lamblichus, describes one of Pythagoras music purification ritual:

“Pythagoras believed that music produced great benefits for health, should someone apply it in the appropriate manner…. And he also called the healing from music that very thing, a purification. …He placed in the middle someone who could play the lyre and settled around him people in a circle …., they seemed to become happy, unified, and directed.”

Plato is equally clear that music reaches into our soul. A well‑known passage, of the Republic, Book III (380–375 BCE) is often quoted as: “Musical training is a more potent instrument than any other because rhythm and harmony find their way into the inward places of the soul.”

To me, these ancient texts seem to describe what many people experience in a sound bath today: sound reaching “the inward places of the soul” and frequency  switching on the body's innate capacity to heal and find harmony.

Bells, Bowls, Gongs and the Modern Sound Bath

Fast forward many centuries and across cultures: Christian bells, Himalayan bowls, and Southeast Asian gongs marked the hours of prayer, called communities together, and accompanied singing, meditation, rituals, celebrations, and key life moments such as weddings and funerals.

These instruments are “cousins” of the bowls, gongs and chimes used in sound baths today.

When you join a sound bath, you’re stepping into the same circle Lamblichus described: people gathered, instruments chosen, and a shared focus on harmony and renewal.

Briefly: How Sound Healing Works in the Body

Ancient philosophers spoke about the “music of the spheres” and the “inward places of the soul.” Contemporary science gives us a different language for some of the same experiences.

Vibration and Resonance

Sound is vibration moving through air, bone and fluid. Every part of your body—organs, tissues, even individual cells—has a natural frequency at which it tends to vibrate. When a bowl or bell is played, its waves pass through you; some part of the body begin to oscillate in sympathy if the frequencies are close enough.

This is the principle of resonance, like one tuning fork beginning to sing because another, tuned to the same note, has been struck nearby.

Sound‑healing instruments are chosen for their stable, clear tones.

As you bathe in their sound, the nervous system often shifts from a fight‑or‑flight state into a calmer “rest and digest” state. Heart rate and blood pressure can drop, breathing deepens, and stress chemistry starts to settle.

This is the kind of rest where healing actually happens; where tension you didn't even know you were holding finally release.

Many people describe it as a “massage from the inside out”—waves moving through the body, inviting layers of holding to soften.

Entrainment: Overtones and Brainwaves

 In music, octaves happen when a note doubles or halves in frequency. The pitch changes (higher or lower), but we still hear it as the same note. Many singing bowls and bells create overtones—extra tones arranged in natural mathematical patterns like octaves and fifths. This creates a sound field that is complex yet ordered, which the brain tends to experience as coherent and safe.

This can lead to entrainment, where the brain’s electrical rhythms begin to match an external sound frequency. Gentle, repeating tones can slow brainwaves from alert beta states toward alpha or theta states, associated with relaxed wakefulness, meditation and the edge of sleep.

As the brain slows, the body follows: the parasympathetic nervous system activates, encouraging digestion,rest, immune function, emotional processing and balance.

In essence, steady, harmonious sound gives the brain something peaceful to align with—helping the whole system move from effort into ease and healing.

An Invitation

You don’t need to remember Pythagoras, Lamblichus or the physics of entrainment to receive the benefits of a sound bath. When you arrive, you simply lie down, get comfortable, and allow the waves of sound to move through you as the body responds in its own way and time.

But if, like me, you love to know the roots of things, it can be interesting to remember that you’re stepping into an old, cross‑cultural art of tuning body, mind and spirit back toward harmony—one breath, one vibration, one note at a time.

I’d love to welcome you to my next sound bath, where you can rest, receive, and let the sound support you in returning to yourself.
