It has been 30 years since Dr. Kuo-huang Han was invited by Prof. MA Shui-long (1939-2015), the former President of National Institute of the Arts (renamed Taipei National University of the Arts in 2000, hereinafter TNUA) and former Chair of the Department of Music, TNUA, to start gamelan and world music classes in order to broaden students' vision and foster proper etiquette for respecting other cultures. Later these classes brought fantastic influences in Taiwan. Dr. Han assisted the university to purchase the first ever set of gamelan in Taiwan, a Balinese gamelan angklung in 1985. Later in 1992 he was re-invited by TNUA and added a Javanese gamelan to the collection in 1993. After Han returned to the United States, I continued to teach gamelan at TNUA under his instruction. This paper focuses on the gamelan class at TNUA, discusses the origins, retrospective history and progression of gamelan at TNUA and Han's philosophy and pedagogy for teaching gamelan. Students enjoyed learning gamelan in Dr. Han's classes enormously. He encouraged students to not only focus on one instrument but learn more of the various musical instruments in the gamelan ensemble. Thus he asked students to interchange musical instruments and applied an idea of "got it teaches not yet getting it" learning from each other, i.e. "those who have learned it teach those who have not yet learned it." Through this teaching strategy, students became accustomed to learning from each other which strengthened their knowledge and skills and also taught them to be cooperative with their peers. This strategy enlightened and inspired me to combine the gamelan course into a type of service-learning class for the 2014 spring semester. Students, particularly the offspring of new immigrants in Taiwan who had come from Southeast Asia, were invited to play gamelan and to learn more about their mother culture. As a result, the gamelan service-learning class on one hand inspired students to be more enthusiastic in the classroom and strengthened their learning efficiency; on the other hand it fulfilled a need in Taiwan's modem and multi-ethnic society to introduce Southeast Asian culture to Taiwanese people and to foster an appreciation and respect toward other cultures.
