About ThirdTone

Sound is more than something we hear.

It is something we feel. It is a relationship that transforms us.

A listener receives fine waves of sound through the ear and across the chest.

A relational experience of sound

At the center of our work is the boundless potential of dissonance.

Growth occurs by increasing our capacity to stay with the dissonance of life's challenges.

What is dissonance?

Textured earth and stone evoke tension and growth in life.

In life

01

Discomfort, uncertainty, and growth potential

Dissonance is a reflection of life's challenges.

Rippling water visualizes interacting frequencies in sound.

In sound

02

A relationship between frequencies

Waveforms create interference patterns. Their tension and movement invite change.

A figure rests at the threshold of water and reflected light.

What if listening can help us meet life more fully?

Enter ThirdTone

A meditative human figure visualizing the response to binaural tones. Two tones create a perceived third tone. A first tone enters the left ear and a second tone enters the right ear. Their auditory pathways interact in the brain. A third-tone response travels downward from the brain to the heart and expands through the body. 01 — FIRST TONE LEFT EAR · COOL FREQUENCY 02 — SECOND TONE RIGHT EAR · WARM FREQUENCY 03 — THE THIRD TONE THE DIFFERENCE, PERCEIVED WITHIN 04 — WHOLE-BODY RESPONSE A RHYTHM FELT, NOT HEARD

Two tones enter—one through each ear.

Each signal crosses into the opposite hemisphere.

In their difference, a third tone emerges within.

A new rhythm moves from perception into experience.

Evan Premo

Through exploration

A lifelong musician fascinated by resonance and overtones, Evan has always used music to explore identity. After suffering a stroke at the beginning of the pandemic, his recovery became a spiritual awakening that revealed sound's profound ability to shape consciousness.

Evan has performed at Carnegie Hall, appeared on NPR's Performance Today, and received commissions from leading ensembles. He is the Artistic Director of Northwoods Music Collaborative. He is influenced many teachers, including by Diana Gannett, Jan Sandman, Pauline Oliveros, Cynthia Bourgeault, Psiilocybe Cubensis, and White Birch. Through ThirdTone, he bridges experimental composition, therapeutic sound, deep listening, and precision acoustic engineering.

“Every sound contains a universe.”

Lisa Masé

At the threshold

When Lisa was four years old, her heart stopped. She entered a luminous realm of color, vibration, and unconditional love. She returned carrying a question that never left her: how can we access unfiltered awareness and connection without physical trauma?

Lisa is a Board Certified Holistic Nutritionist, ISTA-certified Sound Therapist, and author of The Culinary Pharmacy. She is influenced by many teachers, including W.A. Mathieu, Jan Sandman, Georgij Gurdjieff, David Winston, Amanita, and Ayahuasca. Drawing from functional medicine, somatic practice, and the traditional healing frameworks of her childhood in Italy, she brings research, ritual, and therapeutic insight to ThirdTone.

“Listening is a radical act.”

Entheoacoustics™

The relational ecology of sound

Entheoacoustics™ is the study and practice of the relational ecology of sound.

It explores how the architecture of sound shapes relationships between physiology, perception, consciousness, and the living world.

ThirdTone advances this emerging discipline through research, education, artistic practice, technology, and precision acoustic experiences.
