Henke studied at the Rotterdam Conservatory and when he returned, he arranged Oberlin residencies for two of his teachers from Holland. He continued his studies in the summer and began offering eurhythmics as a Winter Term project. Since the 1980s, Henke has regularly taught two eurhythmics courses as well as basic aural skills. Eurhythmics is an approach to musicianship development based primarily on physical motion and experience. The movement part is generally referred to as eurhythmics.
Improvisation is a third element of eurhythmics.
One thing that I think is extremely important about it right now is that it works very much on focusing attention. I don't think there are fewer children being exposed to music. But I do think there are fewer children really being thoroughly taught in music education. In fact, Henke says the eurhythmics approach has applications not only in musical and stage performance, but in therapeutic fields as well, where it is used widely to help mentally retarded and behaviorally disturbed patients improve their attention span and self-control. Henke began his career at Oberlin as a music educator, teaching conducting, keyboard skills, and techniques in secondary music education.
