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

New 7-Week Live Video Training Starts
Wednesday, January 11, 2023

Activate and unleash your energetic voice through empowering and joyful vocal toning and singing experiences that liberate the healing power of your whole-body instrument...

... to express unfelt emotions, heal trauma, and liberate your unique and full expression into the world for a life of ease, vitality, and joy.


What does healing mean to you?

For the much-loved co-creators of Your Big Voice, Isaac and Thorald Koren (the Brothers Koren), emotional healing is a sense of wholeness and integration in which you give all of your feelings the permission to exist...

... and allow yourself to simply be with them in a state of perfect harmony.

As transformational voice leaders, they believe that healing is a biological, mental, and emotional journey of aligning your body through your voice and trusting yourself to feel your full range of emotions.

In Thorald and Isaac’s experience, many people tend to feel a tightness in their voice, which is often a sign that bottle-necked emotions, limiting beliefs you hold about yourself, or the residue of trauma want to come out.

Restricting vocal expression can cause tension or dissonance and manifest as physical tenseness, a sense of stuckness, or energetic, mental, emotional, or metaphysical dis-ease.

Although it’s generally uncomfortable, the Brothers believe that dissonance is a necessary and important phase along the healing journey because it enables you to notice tension and identify where it’s being held and how it’s inhibiting your most luminous self.

With their help, you can move past the challenges that hold back your fully expressive self the issues that you keep buried and hidden inside you through the intentional use of your voice...

... and experience what it feels like to sing or sound out with your whole self, all of you your whole body instrument to gain an exquisite sense of ease, aliveness, and joy.

Different from a portal into better singing, this work is truly about LIVING more freely as all of who you are. With a more liberated voice, you have access to the full range of YOU.

The brothers are deeply compassionate and wildly, radically inclusive, as well as extremely fun to be with. Through a beautiful, loving, and perfectly metered process of building safety and courage, Thorald and Isaac will help you cultivate a loving relationship of gratitude for your voice...

... and find the freedom and confidence to share the true core of your being through song (or even speaking).

They’ll show you how finding and learning to use your voice whether through vocal toning, singing, or song can be one of the most powerful self-healing skills you can acquire.

Join them in a transformational and profoundly uplifting 7-week journey to get in tune with both the harmony and dissonance that exist within you...

... and use your voice to honor and digest your emotions, and allow yourself to reawaken your resonant health and wellbeing.


During this unique and highly experiential 7-week course, you’ll:

  • Discover your sonic body, get in tune with the healing power of your voice, and liberate and align your whole-body instrument
  • Participate in powerful and unique techniques you can use time and again, as well as fun and embodied singing practices to strengthen and loosen your sonic body and gain mind, body, and spirit equilibrium
  • Discover the benefits of vocal toning, singing, and song through any dissonance and discomfort in your body, mind, and soul
  • Explore the 24 tones of your sonic anatomy to experience and express a range of emotions with sound
  • Gain a deeper understanding of where emotions reside in your body and what they sound and feel like, so you can find alignment and tone for emotional release
  • Learn how to use your voice to integrate, metabolize, digest, and heal trauma and unexpressed feelings
  • Recognize how you can use music to express and balance your feelings, body, and biofield, using somatic and subconscious sound therapy
  • Experience what it’s like to use your voice in collaboration and harmony with others
  • Stretch the boundaries of your expression liberating your sonic instrument and become your own healing practitioner
  • Access and experience your voice in a whole new way using intention, attention, harmony, and melody to awaken your vitality and aliveness
  • Reclaim your joy for sounding and singing out what it feels like to be you and alive, as you form a rich and satisfying new relationship to your voice
  • Explore and use your voice from a more whole and embodied perspective, using toning, placement, and what the brothers call sonic intention
  • And much more...

Isaac and Thorald, accomplished musical professionals who’ve played with some of the world’s most celebrated musicians, emanate a profound generosity of spirit.

They’ve used singing as a way to work through their own significant life challenges. And, as two of the most attentive, empathic teachers you’ll encounter, they’re bound to inspire in you an instant rapport and ease in their presence.

And, it’s important to stress that this program is not designed to help people sing better. Instead, it’s meant for anyone who longs to let their heart come forward through their one-of-a-kind, true voice.

As this course unfolds, you’ll have many opportunities to sound out what it truly feels like to be you, and only you. Through the brothers’ practical and powerfully activating exercises, they’ll guide you to attune to your innermost frequency, your brainwave equilibrium, your breath and heart rhythm...

... and let it all ring out the harmony and the dissonance as you hold the intention of healing.

They’ll gently lead you through the sacred practice of warming in, to reconnect with whatever’s happening inside you, in the moment, and safely give it a voice.

You’ll learn how to scan your body for dissonance, syncopate your biorhythms, and elongate your breath all using your voice.

The brothers will incorporate brand-new work, including the 24 tones of your sonic anatomy, and play with musical modes, archetypes, and (just a little) improvisation.

Always with their palpable kindness and heart, they’ll walk (and sing!) you down the compassionate path of receiving yourself and liberating your expression (no matter how messy you may think it is)... and provide you with tools, techniques, and singing practices you’ll need to flow through this process.

You’ll also have the great opportunity to work with another of our beloved Shift Network faculty the celebrated creator of Biofield Tuning, Eileen McKusick.

And (without giving too much away!), the course will culminate in the vast joy of experiencing your voice in creativity and harmony with others.

By the end of the program, you’ll be your own sonic healer, knowing how to use music to reinvigorate your health, vitality, and overall wellbeing through the musical expression of your unbridled voice.

“Awakening a beautiful sound from within me has been the most fun, surprising, and freeing experience I have had in a really long time!”

I had never thought of myself as a singer. I was also acutely aware of the restriction I felt when I wanted to make a sound, hum, or speak up. And I was ready to be free of that. Awakening a beautiful sound from within me has been the most fun, surprising, and freeing experience I have had in a really long time! I didn’t do the course to be a singer, but I am singing! Freely! And I like it!!! Feeling my body as an instrument that was made to make music is utterly beautiful. My energy is brighter, I’m happier, and my health has improved in a most beautifully surprising way. I totally loved the experience with the brothers, the best traveling partners you could wish for.
