Article written for Waldorf Today, March 2015

What is ‘The School of Uncovering the Voice’?   The simple answer:  It was founded in 1924 by the Swedish singer, Mrs. Valborg Werbeck Svardstrom in collaboration with Rudolf Steiner.   Mrs. Werbeck wrote her experiences and spiritual understanding of the human voice in her book, “Uncovering the Voice, The Cleansing Power of Song”.  She composed hundreds of singing exercises which were carried to the next generation by J├╝rgen Schriefer.  It is a holistic approach to singing that is in the early stages of being known in our time and Werbeck’s singing exercises are taught in some Waldorf teacher trainings.

As administrator of The School of Uncovering the Voice in California, I am often asked to share my own personal experience of Werbeck Singing.  In the words of Christiaan Boele, (who has devoted over thirty-five years of his life to teaching Werbeck singing around the globe); “This work meets people where they are at.”  

 Every human’s voice and life story is as unique as their fingerprints.  It is my hope that by reading the narrative of one person’s journey with Werbeck singing, some of you might become inspired to explore the possibilities for yourself.  And so I offer you a glimpse into my involvement with this work as I have gone through the process, from novice to teacher.

In 2001, I spent time with my friend at the American Eurythmy School in Weed, CA.  I asked her, “Is there a spiritual approach that utilizes the voice in such a way as Eurythmy does with movement?”  Her answer was, yes in fact there was, and I was invited to a weekend singing course with a visiting teacher, Christiaan Boele. 

 So, in a pre-cell phone era, on a Friday evening, I embarked alone for a long drive from the Humboldt coast (where I was a student teacher), through the Shasta-Trinity National Forest, eager to attend my first anthroposophical singing class. As my old Buick turned the blind corner of a windy road on the edge of a dark mountain, it violently collided into a huge boulder, surrounded by rubble from a fresh rockslide.  The tire and its rim were instantly wrecked, yet somehow I was able to propel the car forward and safely off of the pavement; thudding tragically down a dirt road that appeared out of nowhere in the wilderness, bouncing to a dusty halt in front of one lone house.  There I met amazing, angel-helper- humans who were able to jerry-rig the Buick’s spare donut tire onto my car and send me on my way for the remaining two hour drive to Mt. Shasta.

After almost not making it there at all, the next morning I attended my first Uncovering the Voice workshop. My perception of what it means to emanate song as a human being; of the potential of creating music with a group of other humans; and even my understanding of the very nature of sound in our world- all was unequivocally changed.  We entered into the realm of pure cosmic tones and were led there through a process that contained holiness, sensibility and humor.  It was indeed a spiritual awakening, yet simultaneously compounded with a deep yearning and sadness.  The weekend course seemed as a moment ‘out of time’; an experience that couldn’t possibly be re-created in the everyday world.  I felt privy to a mystery school; as if I had been invited to share in a rare teaching that was only known among the Eurythmists and other esoteric-type folks. 

The magical weekend ended and I returned to ‘the real world’.  I managed to get on Christiaan Boele’s email list and periodically received invitations for lessons and courses that were offered in CA each Feb. and June.  At that time, the 2nd Foundational Singing Training was beginning but life circumstances prevented me from signing up. There was also a Therapeutic Werbeck Singing Training being offered in the US by another teacher, but I was advised to master the foundational understanding of Uncovering the Voice before learning the therapeutic applications.   Over the next seven years, I attended the Open Course (now called the Annual Singing Retreat), had private singing lessons and went to Werbeck singing workshops at Waldorf conferences.  I wrote down every Werbeck singing exercise that I learned and kept them alive by sharing them with my Waldorf students and colleagues. 

 In 2008, at long last, I enrolled in the 4th Foundational Singing Training and my in-depth study of Uncovering the Voice truly began.  What had once seemed to me as a rare and obscure singing occurrence became familiar and attainable.  With the masterful guidance of Christiaan Boele’s instruction, I gained a spiritual understanding of the process of singing and the Werbeck exercises worked their magic of opening, clearing, balancing and strengthening my instrument.  After completion of the 3 ½ year Foundational Training, I enrolled in the Pedagogical Training and learned how to become a teacher of Uncovering the Voice.  In 2013, after demonstrating my teaching abilities, I earned my teacher certification in Uncovering the Voice, and I am now bringing the work further into the world in my own unique way.  Singing is a lifetime of endless growth and possibilities and I continue to take lessons and advanced graduate courses with Mr. Boele.

For the past seven years I have served in an administrative capacity for The School of Uncovering the Voice and have thus witnessed the transformational process that people have undergone as they’ve immersed themselves in Werbeck Singing.  I have seen advanced, classically-trained, professional singers burst into heart-wrenching tears, wishing that they had found this singing school decades earlier; feeling that at last they were singing in their own authentic voice.  I have also seen people with severely compromised singing abilities undergo a healing process; they are uplifted with confidence, joy and knowledge that they are able to discover their vibrant and beautiful singing voices.  In these courses, all levels of singers become as equals, learning and transforming together.  This process will meet you where you are at.

The School of Uncovering the Voice is a flame of hope for the potential of our relationship to our individual voices, to each other as we unite in song and in our connection to the song of life itself.  With each person that embodies this work, it continues to evolve in creative and artistic applications.  In the United States, there are now approximately one hundred graduates of the Foundational Singing Trainings and there are a small handful of people who have earned teaching certificates from Christiaan Boele. A new Pedagogical Training has just begun and hopefully more teachers will be emerging in the coming years. The 6th Foundational Singing Training in CA will begin this June. 

May the work of Valborg Werbeck Svardstrom continue to blossom in our communities and shine into future generations.  May all people be able to sing with well-being, liberation and beauty.

6th Foundational Singing Training

The 6th Foundational Singing Training in California

at Ananda Meditation Center, Nevada City, CA

The 6th Training meets over a 3 1/2 year period, for 5 days each June and 3 days each February. It includes four private lessons per year, group work and choir.

This advanced course is offered to those with previous study of Uncovering the Voice (such as attendance at an Open Course and/or private lessons with Christiaan). 

In this work, the process of singing is viewed holistically, with the aim of the natural opening and balancing of the voice.  The singer is invited to move with confidence and joy towards discovering his or her own voice within the group and in private lessons.  It is a gentle process and the voice is never pushed, but gently liberated through engagement and active participation.  A wide range of specific singing exercises will be developed together with a comprehensive study of Werbeck's book.

Singing Training Topics:

Session 1:  Exercises to Forget the Breathing    June 11-15, 2015

Annual Singing Retreat 2015

Why attend the Open Singing Retreat?

In various areas of our lives, many of us are now looking for healthier and more holistic approaches and we are feeling a new sense of responsibility for realms such as nature, food, clean air, clean water, etc.  Until recently, people have taken both their speaking as well as their singing voices for granted, as if they come for free and do not require any nurturing.  The renewing thought which the School of Uncovering the Voice brings is that we need to take care of our voices in different ways than was done in earlier days.  

How can we develop our precious, own instruments according to the needs of our times?  In earlier eras of humanity, the singing voice was a central issue in life.  Now our capacity is shrinking rapidly.  We need caring ways of expressing ourselves through our voices and to realize: Through my voice, I express my whole being and by singing, I affect my overall balance and health.  This can be done by the exercises given by Valborg Werbeck Svardstrom, who shows us easy ways to build up relation to all the basic elements needed for singing and care of the voice.   

In a joyful way, we try to experience the musical world as well as to understand the background of our doing; embracing both practicality and understanding.  Werbeck states that if there would be more singing and more righteous singing in our world, the criminality would decrease.  This thought can be understood as follows: Being with our voice connects us to more pure parts of ourselves and develops that what we may as human beings want to become (our more realized selves).  

The Open Singing Retreat provides a safe, welcoming and deeply renewing space in time to do all of this and more.  It is not only for trained singers, but it is also for people who do not yet have faith in their own capacity as singers and who are open to trying new experiences.

Singing is a primal human urge, with the potential for the expression of the core of our being.

Song has accompanied life through the eras of human culture. It holds its ever important place in cultural activities, rituals, and religious ceremonies, as well as through the work and play of everyday life. As a testimonial to this, we find folksongs fitted to the passing of the seasons, festivals, holidays, professions, and almost every other area of life, all across the world.

Today, it is becoming increasingly difficult to find, and develop our most precious and personal instrument, the voice. The School of Uncovering the Voice comes as a timely path to discovery and expression of the individual identity in each voice. From a range of highly differentiated exercises, the healing and regenerative powers of the voice are set free.

Through this process, singing comes to hold more than ever the potential for expression of the innermost core of personality. It is a path to encounter oneself, and tune to inner harmony.
