The system known as eurhythmics focuses on developing one¡¦s rhythmic potential through the use of his or her own body. Through experiences with natural movement, eurhythmics offers opportunities for developing keener hearing, concentration, mental alertness to musical elements, rhythmic control, coordination, flexibility, recognition and understanding of musical symbols, and appreciation of expressive qualities of music. There have been some choral educators, conductors and directors engaged in training choirs by eurhythmics. Taking Taiwan¡¦s Protestant Church Choirs as a research sample, this study analyzes the application of eurhythmics concepts during rehearsal. This result could be a guideline for those who direct or train church choirs. There are five chapters in this thesis. Chapter one contains the ideal, worded as a hypothesis, and poses questions to be pursued in this study. Chapter two briefly introduces the performing style, levels of choir members¡¦ education, and directors¡¦ training in Protestant Church Choirs in Taiwan. It then discusses the possibility of rehearsing choirs by eurhythmics. Chapter three cites available research material and commences on its implications for the topic. Chapter four plays the results in tables and then discusses questions that remain to be solved. Chapter five draws conclusions briefly, then make reflections and suggestions.
