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


Explore your voice as a tool for harmonious living — and find calm and vitality within as you learn to sing in chorus with others (no previous music experience required!).

Nothing exists without music, for the universe itself is said to have been framed by a kind of harmony of sounds…
— Isidore of Seville

You know the ecstatic feeling of singing your heart out with your favorite playlist while driving along an open road...

Why does that bring such a strong sense of freedom and empowerment, like you’re moving full throttle in union with everything around you, belting it out along with the singers who touch you the most — and nothing can stop you?

Song is such a powerful way of connecting to that fully alive, completely immersed, uncomplicated place inside...

Imagine how much more sublime that feeling would be if you were singing in harmony with othersexperiencing your voice blend into something more vast and transcendent than you can create on your own?

According to the much-loved Brothers Koren, transformational voice leaders and co-creators of Your Big Voice, the power of harmony, both musically and as a state of being, can provide you with a sense of vitality, enhanced overall wellbeing, safety, and, above all, belonging — which is something many of us long for in these fractured times.

With Isaac and Thorald Koren’s guidance, you can learn to use your voice — what they call your whole-body instrument — as an expressive tool to create harmony within yourself, with others, and in the ever-changing and complex world around you.

Isaac and Thorald have designed this uplifting hour-long event to help you unlock that harmonic potential in your voice and guide you toward richer, more resonant vocal expression — whether or not you think you can sing — opening you to both personal insights and communal experiences for a life of greater peace and joy.

If you’re familiar with the Brothers Koren, you know that they’re two of the most attentive, compassionate teachers you’ll encounter. You’ll feel an instant rapport and ease in their presence — even if you’re an I’m-not-a-singer type. They have a kind and loving way of helping you break through that illusion.

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

And, in this hour, you’ll have plenty of opportunities to do just that. They’ll guide you in two vocal practices, one to help you tune in to what they call your unique sonic frequency YOUR signature note — tapping into your internal symphony for a deeper sense of self-awareness and alignment with your whole being. The aim is for you to find inner harmony, groundedness, contentment, and tranquility as you discover rich, often untapped layers of your own voice.

You’ll then experience singing with the Brothers, in harmony and dissonance — the tension that occurs in your body and mind when you’re feeling unsettled. Musically, dissonance is a combination of sounds or musical notes that people might find unpleasant when heard together. Yet it can also represent quite a beautiful moment of suspension right before harmony returns.


In this uplifting musical event, you’ll:

  • Understand what harmony is, with a peek into the music theory behind it, and how to harmonize easily with others to foster a sense of abundance, joy, connection, and shared experience
  • Experience your voice as a medium for effective communication and creative expression that opens up a renewed sense of personal empowerment and community engagement
  • Find your unique sonic frequency by tuning in to your individual essence and vibrational identity — for greater clarity, belonging, and inner peace
  • Learn how to create the most common musical harmonies as you experience building simple chords with your voice along with the Brothers Koren
  • Trust that you are innately musical — whether you think you can sing or not — to unlock unapologetic freedom

There’s just something so mysterious and extraordinary about the way harmonic notes meld together. And singing in chorus with others develops teamwork, creating something stunning and disarming that one voice alone can’t hold.

Yet, this workshop isn’t just about making beautiful music together. Singing harmoniously with others can also soothe the ache of isolation and disconnection that a world in turmoil can bring.

The Brothers’ goal is to provide you with practical and simple tools, using your voice, to move from a state of dissonance to one of harmony, from conflict to peace, from illness to vitality, from confusion to clarity, and from loneliness to a sense of belonging.

When you join Isaac and Thorald for this event, you’ll also be among the first to hear about their brand-new 7-week live video course, in which they’ll take you on a deeper exploration of attaining harmony through your voice.

They’ll engage you in a variety of fun and transformative games and exercises to bring you into harmony with yourself, your community, and the universe — as you increase your creative potential and celebrate your artistic soul self-expression.
