Brothers Koren + UNLEASHING YOUR BIG VOICE.jpg

**Meet** Your Guides

Thorald and Isaac Koren are coaches and mentors for expanding creative expression and leading people to a more embodied experience of their own voice. With over twenty years as teachers, performers and transformational leaders, the Brothers Koren are on a mission to hear the World’s song, one Big Voice at a time.

THORALD KOREN

Thorald Koren is a voice and behavioral coach, singer, and multi-instrumentalist. As a vocal producer, Thorald coaches people on forming a new relationship to their brain, body, and voice, guiding them to become "comfortably uncomfortable" with their own biological alarm systems, therein allowing themselves to be radically free to express themselves fully and powerfully, and be present to the experience of singing.

ISAAC KOREN

Isaac Koren is committed to serving transformation through creative expression. His passion is to hold space for people to realize and embody their innate value through the mirror of songwriting. He is focused on exploring the receptive side of the human voice, where deeper listening brings expanded expression and the transformative power of song on the human being.

**Learn** all about yourself again

Remember how musical, valuable and distinct you are! Even if you’re an I’m-not-a-singer type, we'’ll help you break through that illusion — inspiring you to believe you can do anything. *And you can.*

What Will You Learn?

You will have a chance to work with three basic pillars of the Brothers’ twenty years of experience, coaching, and research.

EVERYONE IS MUSICAL

You are made up of the music that has moved you throughout your life. Through a series of games, inquiry and self-learning, the Brothers Koren have a simple and practical way of understanding you as a musical being and helping you hone in on your voice.

YOU ARE A DISTINCT WHOLE BODY INSTRUMENT

LEARN TO LOVE the feeling and experience of SINGING! Through 20 years of voice and Behavior coaching, We have discovered that everyone, when back home in their body, has a radical and distinct voice that needs to be heard and felt. We have developed specialized tools and techniques to access your Big and one of a kind voice.

YOUR STORY IS VALUABLE

Chances are, some of you have been walking around feeling like your life is not interesting enough or worthy of expressing through singing song, or not enough to justify singing out. “Who do you think you are?” Your Inner Critic and small voices in your head may say this and more to you, to silence you... Now’s your time to sound out what it feels like to be YOU!

Voice Page Quotes

Katherine Woodward Thomas

NY Times Bestselling Author of Calling in “The One” and Conscious Uncoupling

“Though singing and songwriting were my first love, I’d sadly left them behind when my life flowed in other creative directions. Yet Isaac and Thorald breathed melody and lyrics back into my heart and soul by taking me under their angel wings and mentoring me home again to my own artistry. The lyrics that have poured out of me under their encouraging and kind care are the best I’ve ever written, and the songs we’re creating together make me feel whole, happy and blessed beyond measure.”

Justin Michael Williams

Author, transformational speaker and musician

“Quantum leap are the two words that best describe my life changing experience with [BK]. Within a number of months I transformed from being a guy who 'wanted to be a singer' into a full-fledged recording artist with a product that rivals a major label release.”

Rikka Zimmerman

Global Consciousness Leader, speaker and coach

“I have always wanted to be a singer, and I had lost my ability to sing with all my heart. Isaac and Thorald were genius at helping me open up and fully express myself.”

STORIES OF TRANSFORMATION

Voice Page Transformations

Katrina Sylvan

“Never having written a song in my life, part of me thought it would be impossible. Isaac and Thorald held a powerful space and my fear turned into a wild adventure of total surprise. I felt a sense of inner freedom like no other. What came out surprised me fully and changed me profoundly.”

Monique DeBose

“Finding the right producing partners was a dream I held for many years. I’d made amazing projects in the past but as the next project was emerging, I knew working with smart, intuitive, compassionate and ‘crazy talented’ people was key. Isaac and Thorald were able to guide me to my music that was ready to be heard. They make a phenomenal team - they compliment each other gracefully and as a result, make magic every time they work with an artist. I am blessed to call them my brothers.”

Emily Leeb

“My journey with BK recalibrated the frequency of my being. I’m now attuned to courage, artistry, self-love and self-expression in an exponential way. I am forever transformed. This caterpillar is now a butterfly.”
