New! "The Polyvagal Theory in Voice Practice" Basic Course I and II

Free from Hashimoto ... a book full of healing stories

The book by Christa Langheiter is completely new.

“Free from Hashimoto” is a book full of healing stories from women, which is particularly close to my heart during this difficult time. How we strengthen our immune system and how strong our self-healing powers are is currently not discussed at all.

In this book you can also read my healing story, which is supposed to encourage the fact that so-called incurable diseases are also curable. Looking back, I can say that from the beginning of my life I had a chronically dysregulated autonomic nervous system, which had led to chronic illnesses in my life. Finding and raising my voice not only regulated my nervous system but also helped me heal from serious illnesses.

The liberation of the voice...

In times of crisis, when singers or artists find it very difficult to survive, the very own voice is more in demand than ever. It needs a different pedagogy, but also new forms of arts and formats. It needs courageous singers and artists who go their own authentic way, who act connected to their heart and are willing to show themselves really open and vulnerable.

Singing, the arts urgently need creative minds that reclaim the beauty of singing through authenticity, truthfulness and presence. What good is an art that is hardly differentiated and in which capitalist structures play an increasingly important role? What about the diversity and individuality of each artist? Doesn’t our world only become colorful because there are so many different voices?

What about the longings, the dreams and visions of a singer? Where have they gone?

With my offers I would like to encourage singers, musicians and artists to go their very own way. The access to one’s own true voice plays a significant role, as well as the free sound. This includes the development of the creative potential.

My name is Iris Hammermeister. I am the founder of the Institute for Applied Improphysis®. I accompany singers, musicians and artists to their own voice. I am concerned with the free sound and the very individual authentic voice.

In my voice work it is about the self-organization of the voice. The ear plays an important role in this. To do this, we must learn to listen again. I believe that it is above all, about listening to non-sung sounds that can be found in the pauses and in the silence.

My listening skills are exceptionally good, coupled with a great love of singing and the arts, students often tell me they feel heard for the first time in my voice training.

My voice seminars now visit singers from home and abroad. Many have studied singing and then lost the easy and playful use of their voice, sometimes even the joy of singing. Almost all of them tell me that they can’t find access to their voice and its potential, even though they have been well trained and have tried many singing methods.

As a classically trained singer, voice coach, trauma and systems therapist, I have spent years researching the impact that first contact and attachment experiences have on our voice. I also focus on the creative potential and artistic expression. It is important to me that singers find their lost vitality again, free themselves from old constricting concepts and live their love for music, because the world needs exactly such singers. For me, the body plays a significant role in singing. It is available as a vessel through which the sound flows. All the more important is a permeable tissue. In my voice work, the muscles and fascia play a major role, especially when it comes to self-regulation of the whole system in conjunction with the singer’s formants. The fascia is one of the most vibrationally permeable tissues and when it vibrates, the rest of the tissue resonates with it.

The basis of my voice work is the polyvagal theory according to Stephen Porges. A voice can only free itself and unfold if we have a regulated autonomic nervous system. This is hardly taken into account in vocal pedagogy. This is where my extensive knowledge of developmental psychology and psychotraumatology comes in. Often singers seek help through hypnotherapeutic approaches and are not aware that the voice can re-regulate itself if you know what its natural function is. My approach, formed through polyvagal theory, corresponds to a new paradigm and is a completely different approach to voice training or voice development. I am the leading expert when it comes to merging polyvagal theory and voice development. Meanwhile, I am internationally active and in exchange with leading scholars from home and abroad and actively participate in research groups.

My research on the impact of the First and Second World Wars on our culture and voice, especially on artists, is elemental for a country of poets and artists whose so important heritage has been forgotten. Diversity, individuality and beauty are no longer in the foreground and I see an art that reflects the lost connection of artists to themselves. I see this current crisis as an opportunity to remind people what art really is and what makes an artist. After all, it is the artists who play a decisive role in the development of a society. Without art, dies a society and we will survive this crisis only with the art.

We need the artists, we need a colorful diverse culture, we need diverse voices, we need the arts – without them we will die an internal death.

We are facing a new era of music and art – a music that is allowed to touch again. An art in which spirituality and healing are reunited. An art in which artists use their ME, their individuality, as the basis for their artistic expression. This only succeeds when artists know who they really are.

Be bold, stand up and raise your voice!

I look forward to seeing you!

“Dear Iris, from the bottom of my heart, thank you. For me it was a universal journey on Saturday. Apparently the frequencies speak to something very old in me, I get access to a universal force that communicates through sounds. Difficult to grasp from the mind, not easy to find words for it. A language of origin, a universal language, the sound.”

“You have been able to give me a key to spaces that I did not know existed. Maybe this is the fourth dimension, at least an additional dimension, the sound. I still feel quite sober and at the same time unfamiliar, free. And differently free than I imagined what freedom could be.”
