Uncovering the Voice

Shayndel Adler has been studying Uncovering the Voice since 1999 and received her teacher certificate from Christiaan Boele, who studied with Jurgen Schriefer who learned directly from Valborg Werbeck-Svardstrom.  Shayndel completed the Pedagogical Singing Training and the Foundational Singing Training. She has also served as  the administrator of the School of Uncovering the Voice Trainings and retreats since 2007. 

Shayndel's teaching remains true to Mrs. Werbeck's exercises and is enriched by her understanding of the healing arts, sound and vibrational therapy and prayer leadership.

As a Waldorf teacher with experience in early childhood and the grades, Shayndel has woven the exercises into guided, imaginative journeys appropriate for various developmental stages and has served as a choir teacher, singing instructor and music consultant for teachers, parents and teacher trainings. She has published three songbooks for Waldorf educators.


Shayndel (Sheryl) has a CA Multiple Subjects Teaching Credential and a BA in Liberal Studies Elementary Education from Humboldt State University, Arcata, CA. She studied Waldorf Education at Rudolf Steiner College, Fair Oaks, CA where she also served as faculty in the summer teacher training. She has been a teacher and a mentor teacher for almost thirty years in a variety of settings including private and charter Waldorf schools, public schools and homeschool programs. She is also  a professional prayer leader,  ordained as a cantor through Aleph Ordination Program; a Sound and Vibrational Therapist through Atma Buti School, Boulder, CO;  and a holistic health practitioner trained at Healing Hands School of Holistic Health, Escondido, CA.

More about Shayndel:

I have taken several sessions of the singing circles with Shayndel. There are many different vocal exercises and each one is unique. Some are more challenging than others but they are always fun. There are exercises for encouraging natural breathing and there are ones that address specific health issues.  These classes have given me more confidence in singing. Though we are not moving around much in the class, we are aware of using our whole body. After a session I can feel the positive effects of the exercises. The exercises are hard to convey in words, but we are optimizing the voices we have and yes, everyone can sing! I am always amazed how a circle of beginning singers can sound so good! I will continue with any singing classes Shayndel offers!

After trying out several voice schools, I'm so glad I found Shayndel and the School for Uncovering the Voice. I find that the exercises I learn are quite fun to practice and at the same time, healing for my soul.

Shayndel gently brings rigor and mastery while teaching Uncovering the Voice singing technique. In two years studying, I have completely transformed the way I sing. I use my voice in a healthy way (not hurting my throat), flexible, clear and most of all full of feeling and authenticity.

It is like a happy journey to learn from Shayndel. All the different exercises with the imaginative stories lead me to the path to find my natural voice. Many thanks to you Shayndel!


The way I found the Werbeck method was nothing short of Divine. I'd been looking for a voice teacher for years and when I learned of how the Werbeck method is a spiritual method for singing- I knew I had found what I was seeking. Then when my first lesson with Shayndel coincided with my going onstage for the first time as the lead of the role I'd been understudying, I knew this was meant to be. Doing my Werbeck warm-ups prior to going onstage, has given me an otherwordly confidence and has helped me feel fully prepared. Shayndel is the sweetest and most patient teacher. It's been such a joy to learn from her and I'm forever grateful!

I have always been a quiet, unsure singer. After only a couple of sessions with Shayndel, I found myself singing out; learning to use my voice and body to really sing! It was such a spiritual feeling to sing in the group, with all the voices blending and a palpable vibration holding the circle together. 


Shayndel has a lot of experience and is very professional, yet at the same time is always caring and encouraging.

Uncovering the Voice lessons with Shayndel is an immersion into the direct experience of healing through singing and sound. Shayndel knows the Uncovering the Voice lessons like no one else and in my experience, being led by her is one of safety, assuredness and rest.


Shayndel has a beautiful balance of gentleness and strength which is a reflection of the profound uncovering the voice exercises that she lives and breathes by. I feel so fortunate to have found her and have her be the one to help me to uncover my voice.

Thanks beloved Shayndel for making me and my heart sing.  I have always wanted to learn to carry a tune and as a stretch goal have some beauty in it but before my lessons with you, the best I was ever able to learn was to follow a group melody only if they were singing with great volume. I see that you were correct in saying anyone can learn to sing if taught in the right way for them. In our group classes, numerous people who had been in the same situation as myself were now all singing beautifully.

I have taken singing lessons with Shayndel for three years both in a group setting and individually. Now that we can't meet in person and we live in different states, we have our lessons over zoom. I love the Uncovering the Voice method of singing and I feel such gratitude to have Shayndel as my teacher. In group lessons, I have seen her work with students with a wide range of singing experience and her genuine support and encouragement make everyone feel successful. I look forward to many more lessons with this talented singer and teacher.

Shayndel (Sheryl) Adler has been my faithful student since 2001. She has participated in numerous courses and private lessons throughout the years and has developed profound knowledge and abilities in her own singing and in teaching others. Her ongoing enthusiasm, warm-heartedness and spiritual approach is ever joyful and deepening for all who engage in her classes, lessons and services. Shayndel also has many other fields of expertise and is able to connect singing with spiritual development and thus leads her work from a higher perspective. On numerous occasions, Shayndel has shown deep insight, skillfullness and artistry. She works with all ages, from school children to adults. As one of the leading teachers of this impulse, I have full trust and confidence in her approach.
