This method is based in addition to traditional vocal techniques such as Bel Canto and Functional Voice Training, to the transformative breathing techniques and combines them with motion sequences from Qigong, a system of coordinated body posture and movement, breathing, and meditation, originated in China more than 5,000 years ago.


Kirsten also works as music-researcher and musical director for productions like, f.e. “Weltatem“ with “Het Geluid“, a VR-Opera, where she could join a team of scientists who developed a VR-experience in which the public learned how to breathe and sing, and where each breath and note was made visible and helped singers to link audio and video in an outrageous way.
