This book was created during over 30 years of teaching eurythmy to seminar students. As a physician deeply connected to anthroposophical medicine, the author focused on the language of forms (morphogenesis and metamorphosis) of the skeletal structure, musculature, internal organs, and sensory organs, with the larynx being her particular research subject. In her didactic concept, embryology, the study of human shape formation and organ development, held significant importance. She entrusted the seminar students with carefully formulated, handwritten, and lovingly illustrated scripts, which she regularly updated and had copied anew for each course. This resulted in a unique collection of materials that was originally written solely for the personal use of her course participants and retained a rather personal character until the end.
