Eurythmy is a disciplined art of movement of the arms and body that visibly expresses the vowels and consonants of speech and the tones and intervals of musical melody. In the classroom, eurythmic movements have a therapeutic function in which the child's development is supported and enhanced through its various stages. This article discusses the application of eurythmy in the Waldorf Schools curriculum, where eurythmy is used to enhance speech, writing, music, mathematics, literature, history, and creativity instruction. The development of eurythmy by Rudolf Steiner as a form of expressive movement is described, and the movements and function of eurythmy are defined as the visible equivalent of the musical phrase or the spoken word. The basis of eurythmy is discussed, as is the nature of eurythmy movements. The paper also discusses the developmental approach to eurythmic application, and its use at grade levels from first through sixth grades, including the nature of instruction and the subject matter enhanced by the movements.
