Get started
Can you recall a moment when you were completely in tune with yourself, fully able to express who you are without holding back?
It’s something that eludes so many of us. Yet, all along, you’ve had the tool you need to cultivate this experience in your life.... your own mystic voice.
Isaac and Thorald Koren (the Brothers Koren), celebrated transformational voice leaders and co-creators of Your Big Voice, share that your voice is a sacred instrument — your whole-body instrument — that can calm your nervous system, foster deep inner peace, heal emotional wounds, awaken your divine essence, and unlock boundless creativity.
Using your voice in a gently guided way, the Brothers say, also opens a gateway to your inner mystic — the part of you that actively seeks unity with the Divine, connection with deeper truths, higher realms of guidance, and elevated experiences of bliss and communion.
Despite its cathartic potential, many of us feel too ashamed to sing, letting insecurities block the beauty and meaning our voices can create.
The Brothers are two of the most attentive, empowering teachers (and luminous songbirds) you’ll encounter, with a uniquely kind and loving way of helping people break through these barriers.
They have an incomparable capacity to break your heart open and elicit an intense feeling of expansiveness as you tone, chant, or sing along with them.
When you join the Brothers on the adventurous musical journey of their brand-new 7-week live video course, they’ll help you unlock the hidden power of your voice.
At the heart of this program lies the concept of the mystic voice — the profound, ineffable connection between your vocal expression, your soul’s truths, your connection to the Divine, and the greater mysteries of the Universe. Awakening your mystic voice unlocks a sacred resonance within yourself, reconnecting you with the timeless musical threads of belonging that tie you to your ancestors and ancient traditions — fostering unity, healing, and creativity within yourself and your community.
Throughout the seven weeks of this transformative program, the Brothers will establish a ritual container, in which they’ll guide you through a variety of vocal practices, techniques, meditations, and playful games designed to release fear, self-doubt, and past trauma — thereby bolstering your resilience and awakening your inner mystic.
Using “harmonic breathing” (a deep, rhythmic kind of breathing that slows your heart rate and grounds your body), ritual toning, ecstatic vocalizing, vocal activations, improvisation, and communal singing, you’ll learn to surrender to your vast creative potential — and transcend the limitations of the mundane world to experience the divine within and beyond.
You’ll also have the beautiful opportunity to experience the gifts of special guest faculty Fred Johnson, a spiritual elder of the Inayati Sufi Order, and Eileen McKusick, founder of the Biofield Tuning Institute.
Though it may be difficult to imagine now, by the end of the course you’ll have created your own mantras and songs — culminating in a grand finale where you, the Brothers, and your community will gather together to write and sing a celebratory group anthem — a powerful soundscape blending individual voices into a unified whole.
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 find their deepest essence through their one-of-a-kind, true voice.
You’ll also experience being witnessed in sacred listening circles. These guided, supportive spaces will allow you to share your voice without fear — deepening your self-awareness, building confidence, and fostering a profound sense of belonging and amplified connection to others.
The Brothers Koren will enrich your journey by offering additional pathways to connect with your voice’s healing potential. Their unique practices will help you deepen your understanding of your voice as a sacred gift that enables you to receive and express the gorgeous fullness of who you are.

Your voice holds a mysterious power and is a gateway to your body’s innate healing intelligence and self-regulation. For many people, however, the idea of being truly heard is scary. Fear, trauma, loss, and emotional challenges can inhibit your voice’s full expression.
In this opening module, you'll explore how to move beyond fear, face your inner critic, and reclaim your voice as a sacred powerful instrument.
The Brothers Koren guide you through a variety of techniques that include “harmonic breathing” (a deep, rhythmic kind of breathing that slows your heart rate and grounds your body), and directional toning (sustaining frequency tones sourced from your power centers to calm your nervous system).
By setting positive vocal goals through visualization and harmony-based intentions, you’ll establish a ritual container for your voice and welcome yourself home to your whole-body instrument.
In this first session, you’ll:

Your voice is not just for expression. It’s a powerful instrument for healing.
Unexpressed emotions and unresolved trauma often weigh us down, disconnecting us from ourselves and others.
Explore how your voice can serve as a bridge to ancestral energy, helping you release stuck patterns and find resilience.
The Brothers lead you in a number of vocal techniques, meditations, and activations, including what they call “Singing to the Four Directions of the Heart,” a guided vocal exhalation process. You’ll experience a soothing vowel practice, healing emotional distress with targeted vowel tones using “Sonic Anatomy Ton-ics.”
You’ll also participate in an ancestral-healing voice activation, designed to direct your healing voice to your ancestral lineage.
As you experience profound intergenerational healing, you’ll clear a path to greater states of bliss and belonging.
In this session, you’ll:

Modern life often disconnects us from creativity and joy, leaving us feeling trapped in the mundane routines of our daily life.
This session is designed to help you reconnect with your creative life force and rediscover your voice as a tool for liberation, joy, and bliss.
The Brothers guide through rhythmic Sufi chanting to transmute your fear into blissful states. You’ll participate in a powerful African call and response vocal tradition to access communal joy and break free of your inhibitions.
You’ll also experience a vocal mirroring meditation to reflect on your vocal journey as a pathway toward embodying bliss.
This week, you’ll experience:

Resistance, self-criticism, and fear of change can leave us feeling stuck. Learning to embrace imperfection and occupy the space of your voice can lead to profound liberation and self-discovery.
In this module, the Brothers engage you in free-flow vocal improvisation, playful expression, and spontaneous singing to help you access your truest and deepest self — so you can rediscover your vitality, free your inhibitions, and experience the joy of authentic creative expression.
You’ll experience a vital sound activation, energizing your body and mind with dynamic vocal exercises. You’ll also be guided through what the Brothers call “Emotion in Motion” — sounding practices to release unconscious emotions and cultivate resilience.
In this session, you’ll explore:

Many of us feel creatively blocked, undervaluing our own ideas and expressions. This module reveals your natural creativity and helps you reclaim pride and satisfaction through the alchemy of song creation.
In this session, the Brothers show you how to channel your creative energy through intuitive song practices — trusting your brilliance and letting it flow effortlessly.
They’ll guide you through a vocal-channel practice that offers you the opportunity to let intuitive melodies emerge without judgment. You’ll enter the “cave of your voice” to experience a song meditation ritual, designed to transform emotions into creative works of art.
You’ll learn how to combine rhythm, melody, and harmony into original songs and powerful mantras with ease as you flow through the creative process.
In this module, you’ll discover:

Fear of vulnerability often prevents us from sharing our voice. Yet, being witnessed in a safe and supportive environment can be deeply healing. The act of being fully seen and heard can be one of the most transformative experiences in our personal healing journey…
… because it gives us a strong sense of belonging and connects us to the mystical principle of Oneness.
In this session, you’ll explore the profound power of vulnerability. You’ll engage in sacred listening circles and group vocal practices, allowing you to be witnessed without judgment and fully accepted in your authentic expression.
By participating in mirror voice reflections and guided vocal sharing, you’ll increase your self-awareness, confidence, and self-acceptance. These practices help you realize the immense value in sharing your voice, both for your personal growth and in fostering deeper connections with others.
As you embrace the transformative potential of being heard, you’ll experience increased emotional freedom and a deeper sense of belonging.
In this module, you’ll:

In a world that often feels fragmented and isolating, co-creating music with others can bring you back into harmony and unity.
Group song rituals offer a way to foster connection and shared purpose. This final module invites you to experience the power of group voice to create intentional energy shifts and community healing.
Through intentional song creation, you’ll learn to blend your voice with others, creating a soundscape that carries transformative energy for the group. In a vocal circle, you’ll witness the power of music to heal, unify, and transform.
You’ll end this journey understanding the importance of collective vocal expression and how it can elevate the individual and the community.
In this closing session, you’ll:
