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

New 7-Week Live Video Course Starts
Wednesday, February 21, 2024

Take a musical journey to reveal your voice your unique sonic frequency and personal vibrational identity as a tool to find greater clarity, belonging, and inner peace, as you learn to sing (and BE) in harmony with others... no previous music experience required!

Education in music is most sovereign because more than anything else rhythm and harmony find their way to the innermost soul and take strongest hold upon it

Remember when you were a kid and your favorite song would come on the radio? You’d grab a hairbrush to use as a makeshift microphone and sing your heart out without the slightest concern about the quality of your voice.

And wasn’t it even more fun when good friends were singing along with you, belting it out together with complete abandon? What a joyous way to connect and create bonds to feel a part of something important... and everlasting.

According to the much-loved Brothers Koren, transformational voice leaders and co-creators of Your Big Voice, song is a potent vehicle for connecting to that fully alive, engaged, uncomplicated place inside...

And the power of singing with others especially in harmony can provide you with a sense of vitality, self-trust, and enhanced physical, mental, and emotional wellbeing.

Even if you’re among the many people who think you can’t sing because you don’t have the spectacular musical finesse that you admire in your favorite vocalists, or you just don’t trust your own pure expression... singing in harmony isn’t as hard as you may think.

Not only that, but when you experience your voice blend with others into something more vast and transcendent than you can create on your own, you’re likely to find a sense of accomplishment and acceptance that can be hard to find in this often divisive world.

Join Isaac and Thorald Koren for a brand-new 7-week course, in which they’ll guide you to use your voice what they call your whole-body instrument as an expressive tool to create harmony within yourself, harmony with others, and alignment with your life, your purpose, and the pulsing patterns of the universe.

While you will learn the basic music theory behind creating harmony and experience a wide variety of fun yet powerful vocal practices to tune your ear to the harmonious notes your whole being wants to release this program isn’t just about making beautiful music together.

And, it’s definitely not about singing “better.” It’s about learning to revel in the one-of-a-kind beauty and sonic identity of your voice... so you can live in harmony with yourself and the world around you, and tap into the vast reservoir of collective energy that’s always just a note away.

Through Thorald and Isaac’s embodied voice work, you’ll learn how sustaining simple vowel sounds and tones can create harmonics, which you can direct to various body areas for real-time healing.

As you let go of inhibitions and your judgmental inner voices and start to freely express yourself through the universal language of music you’ll pave a path toward profound self-discovery, self-trust, and the deep understanding that you hold an essential and unique place in the world.


During this musical journey of personal liberation, you’ll:

  • Learn the basics of musical harmony, and be guided through harmonic practices with the Brothers, uncovering key tones for harmonizing comfortably with others
  • Participate in a wide variety of voice exercises with your newfound musical brothers to find inner harmony and tranquility, expand your connectivity with others, and feel yourself in alignment with your life, your purpose, your soul, and the cosmic plan
  • Be part of a song-writing experience and move beyond inhibitions and into confidence, with both your voice and your own creative process
  • Cultivate your voice as a medium for effective communication and creative expression opening up a renewed sense of personal empowerment and community engagement
  • Find your unique sonic frequency by tuning into your individual essence and vibrational identity
  • Know that you are innately musical whether you think you can sing or not and unlock unapologetic freedom, abundance, and joy
  • Be guided by the Brothers and special guest facilitator Eileen McKusick, into the foundations of demitones and the “Sonic Anatomy” for greater liberation
  • Use a series of healing tones, called“tone-ics,” to attune your whole body and find your true signature note
  • Experience group singing to discover freedom and liberation in the voice you’ve been given and foster connection and shared experience
  • Learn how to cultivate an individualized voice practice to take with you long after this course ends
  • And much more...

The world needs to hear your sound because it’s a powerful reflection and conductor of your soul and an essential part of the uniting harmony that your community (and the world) so urgently needs.

In this course, you’ll learn easy-to-implement vocal tools to help you move from a state of dissonance to one of harmony, from conflict to peace, from illness to vitality, from fear to trust, and from loneliness to connection.

You’ll be guided in creative games and simple processes to help you tap into the music within you and access your unique inner song anytime you desire. You’ll even take part in a collaborative song-writing process!

If you’ve had any experience with the Brothers Koren, you know how present and loving they are, not to mention that they’re two very enchanting singer-songwriters. It’s almost impossible not to feel an instant ease in their presence. Even if you’re an I’m-not-a-singer type, they have a gentle and compassionately metered way of helping you break through that illusion.

What’s even more unique about the Brothers is their unmatched capacity to break your heart open to elicit an intense feeling of expansiveness as you sound or sing along with them.

With Thorald and Isaac as your trusted guides, you’ll discover the healing power of your voice and celebrate your artistic soul expression.

Their goal is to ground you in harmony, both musically and as a state of being, opening you to personal evolution and blissful communal experiences. It’s a journey of self-discovery, an awakening of all your sources of harmony... so you can shape a life that resonates with who you truly are.
