Your voice is the living sound of your soul — the vibration of your true being waiting to be remembered.
So many of us have spent a lifetime suppressing our voices. We’ve learned to hold back what we really want to say — to please, to keep the peace, or to protect ourselves from criticism or rejection. We’ve mistaken quiet for safety, and perfection for worthiness. Over time, our voices grew small, tamed by fear, self-consciousness, and control.
Yet, beneath that silence, your wild heart longs to be heard.
What if the true invitation is to use your voice to shed the fear, judgment, and conditioning that have blocked and muted your vitality — so the natural song of your soul can rise again? What if you can reclaim your brave self in the way you speak, sing, and address the world?
The beloved Brothers Koren — Isaac and Thorald — internationally acclaimed musicians and transformational voice guides, have spent decades helping thousands rediscover the liberation of their own authentic sound. Their rare blend of artistry, neuroscience, and heart-centered facilitation makes vocal awakening not only possible, but deeply joyful.
Their work isn’t about performance or polish. It’s about remembering the raw, unguarded pulse of your creative force — and returning to the brave, playful, expressive being you were born to be.
In their brand-new 7-module, 9-week live video course, you’ll embark on a powerful journey of vocal breathwork, voiceplay, and soul — one that transforms your relationship with your voice and your very sense of self.
You’ll rediscover your voice as a medicine that sounds the drums of awe — a healing instrument that calms anxiety, metabolizes emotion, and calls you back into coherence, courage, and childlike wonder.
Each session will build upon the last — moving from play to emotional release, from personal courage to communal harmony — using your own voice as medicine.
You’ll sing your way into a state of reverent wonder that reconnects you with your purpose, imagination, and the pulse of life itself. (No previous singing experience required!)
Through guided vocal journeys, embodied practices, and the brotherly warmth of a safe, creative community, you’ll remember what it feels like to be a part of something larger — for yourself, your voice, and the greater song of humanity.
This is a journey for anyone who’s ever felt stifled, unseen, or disconnected. Whether you’ve sung on stages or never dared to sing at all, you’ll awaken the wild heart within you — the part that knows how to play, express, and love without apology.
This is a highly experiential and embodied process, designed to unlock your brave voice step by step – from awe-filled creativity to the deep connection of communal song. You’ll emerge with a living practice of vocal freedom — a way of being that continues long after the course ends.
In the Brothers’ nurturing presence, and as a cherished member of a compassionate community, you’ll discover the deep belonging that arises when many voices become one — unique and sovereign, yet harmonized through shared intention.
You’ll also experience a special session with guest faculty Eileen McKusick, sound-healing pioneer and founder of Biofield Tuning, who will guide you through Tone-ics — a process designed in collaboration with the Brothers Koren that uses luminous sound patterns to recharge your system and unleash your life force.

By the end of this program, you’ll know better what it means to be free — not because fear has vanished, but because your courageous and wild heart sings it into submission.
You’ll move through life with greater confidence, clarity, and creative flow.
Your nervous system will feel more regulated. Your emotions will move through your voice instead of stagnate. Your relationships will deepen as you speak and listen from a place of resonance and truth.
And your voice — your raw, radiant, human voice — will finally feel like home again: brave, embodied, and gloriously alive.
Wonder and awe await you. All you need is the permission to let the song that lives within you rise — messy, magnificent, and utterly true.
— Katherine Woodward Thomas, New York Times Bestselling Author: “I Didn't Know How to Access That Part of Myself Until I Met These Two Gorgeous Angel Men”
— Justin Michael Williams, Author, Speaker & Top 20 Recording Artist: “Working With the Brothers Completely Opened Me Up in a Way That I Never Even Thought Was Possible”
In this 7-module, 9-week transformational course, Isaac and Thorald will guide you through the wisdom, skills, and tools you need to experience your voice as medicine — a living vibration that soothes the body, steadies the mind, and opens the heart to awe, coherence, and belonging.
You’ll connect with Isaac and Thorald and experience their teachings through livestreaming video via any connected device. This connection is easy to use and will enhance the impact of Isaac and Thorald’s transmissions. Can’t make it live? After each class, you can stream the video and audio recordings to enjoy anytime and anywhere at your convenience.
This course will feature LIVE teachings, interactive sessions, experiential practices, and Q&A with Isaac and Thorald. Each session will build harmoniously upon the previous ones, so you’ll develop a complete holistic understanding of the practices, tools, and principles you’ll need to let your own sound guide you home — dissolving fear, regulating your nervous system, and restoring the natural harmony between your body, heart, and spirit.

Every true creative journey begins with play.
In this opening module, you’ll be invited to loosen the grip of perfection and step into the unknown — using your voice as your guide. Here, bravery isn’t about performance or polish, but about daring to sound, move, and express without judgment.
Play is not frivolous — it’s sacred. Each imperfect sound, laugh, and surprising tone calls you back to your natural freedom.
As you let go of control and the need to impress, you begin to reconnect with your wild heart and rediscover presence, vitality, and the aliveness of your humanity — opening the door to the voice you’ve been waiting for.
In this opening session, you’ll:

Fear is part of every voice. No matter how experienced or confident we are, it whispers doubts, tightens the throat, and urges us to hold back.
Most of us have been taught to silence or push away fear when we sing or create — yet there’s another possibility... one that opens the door to astonishing song.
You’ll be invited to meet your fear with compassion instead of resistance, creating space for your wild heart to emerge. Rather than judging fear as weakness, you’ll learn to welcome it as part of your humanity — and a vital force within your creative expression.
When you give fear sound — when it’s allowed to tremble, crack, or roar — you can transform it from tension into power, and from resistance into resonance.
During this module, you’ll:

Your voice isn’t meant only for joy or celebration. It’s also the channel through which the entire spectrum of human emotion longs to move — grief, anger, tenderness, joy, and everything in between.
This week, you’ll explore the sonic landscape of feeling that lives within you. These emotional lineages form the deeper music of your being, often hidden beneath layers of silence or suppression.
By daring to give sound to what’s gone unfelt and unvoiced, you unlock new access to your whole heart and whole body voice — and awaken the full range of your body’s natural intelligence and vitality.
Through this work, you’ll come to sense that every emotion carries its own kind of music. Voicing them becomes a practice of integration — transforming overwhelm into coherence, and expression into liberation.
In this session, you’ll:

Your voice is more than simply expression — it’s medicine.
You’ll explore the emerging field of sound and vibrational wellness through the liberating power of tonal patterns. With Eileen McKusick — renowned pioneer in sound healing and biofield science — you’ll be invited into an experience of “Tone-ics,” a codified series of tones designed to reset your system, restore harmony, and awaken vitality.
You’ll learn to attune your body, mind, and heart — discovering how music and voice can release what’s stuck, restore your natural flow, and expand your capacity for joy and aliveness.
In this session, you’ll:

Throughout this class, you’ll explore the science of awe and how it opens flow states in your body and mind when you dare to create freely and make a beautiful mess.
You’ll practice entering awe through sound and songcrafting, inviting inspiration to arrive rather than forcing it. Through playful exercises and guided explorations, you’ll learn to create from wonder instead of fear, trusting that your voice can follow where awe leads.
When you surrender to this state, you open yourself to surprise, delight, and discovery.
In awe, the inner critic quiets, and something larger begins to move through you. Each sound becomes a brushstroke of mystery — a reminder that creativity is less about “getting it right,” but about being available to what wants to come alive through you.
By cultivating awe, you’ll find a powerful kind of bravery — rooted not in effort, but in openness to the beauty unfolding through your voice.
In this session, you’ll:

Singing together is one of humanity’s oldest medicines.
In this module, you’ll step into the tender, courageous act of letting your voice be heard alongside others. Through harmony, call-and-response, and shared rhythm, you’ll experience how sound dissolves isolation and opens the heart to connection.
This is the class where vulnerability becomes strength — where listening is as vital as sounding. You’ll discover the relief of not carrying your voice alone, and the joy of hearing it woven with others.
The invitation here is intimacy — to remember that your voice matters — and that belonging begins the moment you dare to share it. In shared song your wild heart remembers it doesn’t have to sing alone.
In this session, you’ll:

Your closing module will be a celebration — a homecoming for everything you’ve discovered: your courage, your play, your heart, your awe.
Together with the Brothers and your community of co-participants, you’ll gather these threads and weave them into one collective voice.
This final week will be about integration — embodying your personal freedom while attuning to the resonance of the whole. You’ll experience how your individual sound contributes to a unified field of harmony and belonging, and how, in that union, something larger and more luminous comes alive.
As you sing together, you’ll feel your individuality honored even as it merges into community. Courage will become contagious, and you’ll witness how your voice amplifies when joined with others.
This is a sacred completion — a reminder that your voice is a gift, not only for you, but for the greater song of the world.
In this session, you’ll:

You’ll hear how they transformed performance into purpose and why they believe every voice is waiting to lead its owner home. This isn’t theory, but a heartfelt exploration of courage, creativity, and what it means to live with a brave voice in an age of uncertainty, noise, and awakening.
