"Because of interests, they are united together; because of feeling moved, they are persistent." Taipei Municipal Jianguo High School Teachers' Chorus was established on September 28, 1993. For these 14 years, this chorus has been led by four conductors and eight chiefs' leadership. In music, no matter in listening, vocal condition and singing in choir, diverse and rich teaching contents help people to enjoy themselves in a musical world. We sing. We hope to voice healthy and delightful attitude of people from "Jianguo High School." We sing. We hope to add a more harmonious spirit into the whole campus. Through singing, teaching-and-learning atmosphere between teachers and students can be delightful. Furthermore, the educational goal -- truth, goodness and beauty – can be also reached.
