In this article, we, culture bearers and music educators, discuss ways of using East Asian virtual musical instruments to promote culturally diverse music activities in classrooms. We introduce affordable tablet-based virtual instruments (Korean "hyang-piri," Chinese "erhu," and Japanese "koto") and hands-on music activities to help students gain deeper understandings of East Asian music cultures. We provide an introduction of each instrument in its acoustic and tablet-based form, appropriate instrumental techniques to express unique musical and cultural characteristics (e.g., mode, vibrato, and ornamentations), and a teaching sequence of a sample piece. Such a performance-based and culturally diverse musical experience is intended to cultivate students' intercultural sensitivity and attitudes that honor diverse cultures.
