Three hundred years ago, Hakka ancestors established villages along the lower Tamsui River, Linbian River, and Donggang River to resist external forces, forming the "Liudui," which became a collective identity for Hakka people in Pingtung and Kaohsiung. Over these three centuries, due to the conflicts, adaptations, and integrations of diverse ethnic groups, the Liudui area developed unique musical forms not found in other Hakka settlements in Taiwan, such as the Wanzhi Tune, Picking tea tune, Near-Mountains Tune, nursery rhymes, and other authentic southern Hakka mountain songs. Additionally, the region features a special "Chinese-Western Orchestra" phenomenon within southern Hakka bayin music, as well as popular Hakka music creations influenced by social practices and cultural identity, exemplified by artists like Lin Shengxiang, Chen Shuang, and Yan Zhiwen. This course explores the evolution of traditional and popular Hakka music in the Liudui area. Through local cultural activities, guest lectures, and group discussions, students will gain concrete and immediate insights into the development of Hakka music in the region. Furthermore, through field visits and interviews, they will uncover performance challenges and research topics while seeking innovative and sustainable performance models.
