With Transformational Voice Leaders
& Co-Creators of Your Big Voice
Isaac and Thorald Koren


Get in tune with the healing power of your voice as you’re guided to sing out with your whole-body instrument the harmony and dissonance to calm your nervous system, express hidden emotions... and experience a greater sense of ease, vitality, and joy.


We all want to live in harmony…
Harmony has multiple levels of meaning, ranging from feeling deeply peaceful to describing the beautiful blend of qualities we witness in potent music.

We want our whole being physical, mental, emotional, and spiritual to operate in a harmonious way, with all parts of ourselves smoothly and healthily flowing together.

Our lives both internally and externally however, get thrown out of whack from time to time, and our bodies, hearts, minds, and circumstances fall out of sync...

... creating a degree of tension between where we are and where we want to be.

This tension, or dissonance, occurs in our bodies and minds and you can learn how to work with it by expressing it musically through your voice.

In musical terms, dissonance is a combination of sounds or musical notes that people might experience as unpleasant when heard together yet it can also represent quite a beautiful moment of suspension right before harmony returns.

But how does it show up in the body?

According to the much-loved transformational voice leaders and co-creators of Your Big Voice, Isaac and Thorald Koren (the Brothers Koren), dissonance often manifests as physical tenseness, a sense of stuckness, or energetic, mental, emotional, or metaphysical dis-ease.

Dissonance happens when we’re unwilling to feel or express unresolved trauma and emotions... when we’ve left important things unsaid... or when energetic disturbances in our field or physical body cause tightness, dullness, and lethargy.

The Brothers believe that your voice is your greatest instrument for healing both the root cause and the symptoms of these imbalances in your system.

So, what if you could access and offer yourself the freedom to voice ALL of it from the harmony to the challenges?

What if giving yourself the permission to sound out and sing all of what’s happening inside you could elevate your health, make your vitality rise to the surface in your everyday life, and release your luminosity into the world?

With over 20 years of experience performing, recording, teaching, and empowering others, Isaac and Thorald have cultivated a new, loving, radically inclusive, and embodied approach to helping people from all walks of life awaken to the healing power of their own voices...

... as they experience a safe space to feel the unfeelable and raise their vibration and vibrancy using sound.

During this exciting free online event, they’ll guide you to work with tension or dissonance in your body as a point of transformation using vocal toning.

They’ll illustrate how focused attention and the harmonics of your voice can create the positive conditions you need for healing to take place on all levels.

You’ll explore harmonic vowel sounds, low and high pitch, vibrant rhythm, and your unique voice timbre to arrive at your “resonant equilibrium.”


In this highly experiential workshop, you’ll:

  • Be guided through a deeply moving practice to identify and release physical, mental, and emotional tension through the potent medicine of vocal toning
  • Learn how to use your voice as a whole-body instrument to integrate, metabolize, digest, and heal trauma and unexpressed feelings
  • Access and experience your voice in a whole new way using intention, attention, harmony, and melody to deepen your expression and awaken your vitality and aliveness
  • Discover the benefits of vocal toning through any dissonance or discomfort in your body, mind, and soul
  • Begin to reclaim your joy for sounding and singing out what it feels like to be you and alive, as you start to form a rich and satisfying new relationship to your voice

The Brothers Koren will guide you in a sacred voice practice, in which, through your attention and vocal toning, you’ll scan your body for areas of tension physical, emotional, mental, or spiritual...

... and alchemize whatever dissonance you find into deep relaxation, heightened vitality, and enhanced overall wellbeing.

When you join Isaac and Thorald, you’ll also be among the first to hear about their new 7-week course, in which they’ll take you on a deeper journey to awaken your healing voice through song.

You’ll use your voice to honor and digest your emotions, allowing yourself to reawaken your resonant health and wellbeing and ultimately experience the benefit of collaboration and communion, through the voice, in a collective songwriting experience.
