Taking versions of the song “Love of Orchid Island”circulated among Puyuma, Amis, and Paiwan villages as examples, I aim to discuss relations between “tradition” and “modernity” suggested by compositions of Lu Sen-bao (Puyuma Aborigine, Puyuma name: BaLiwakes, Japanese name: Mori Ho Ichiro, 1910-1988). Influenced by Western music education that he received at Tainan Teachers College, he composed a considerable number of songs. “Love of Orchid Island” is one of the popular ones among his compositions. It is not only sung at ordinary get-togethers and festivals in his home village, Nanwang, but also performed on stage by Aboriginal artists. Because it is so popular in Amis villages, many consider it an Amis folksong. Furthermore, one may find this song in various recordings under different titles, and the tracks are arranged in a variety of styles, sung by singers from different Aboriginal groups, with the “nakasi bands,” guitars, or world-beat-style synthesizers as accompaniments. It seems ironic that the composer of “Love of Orchid Island” was an Aboriginal intellectual who had received Western music education introduced by Japanese colonialism, while the song have been circulated in a form of “popular song.” I will argue, however, these two things are not irrelevant. Christian services and “shoka” (Japanese term, meaning “singing”)programs introduced by the then Japanese colonialist government brought in concepts of Western music about scale, meter, etc., to Aboriginal societies, and the introduction of these concepts helped to form Aboriginal “popular music.” To some extent, we may say that the introduction of “shoka” as well as the formation and circulation of popular music represent the “modernity” of Aboriginal societies. Lu Sen-bao received Western music education from the training programs for prospective “shoka”instructors when he studied at Tainan Teachers College. Many of his works, nonetheless, such as “Love of Orchid Island,” become “popular songs” circulated among Aboriginal villages. Therefore, we may look into a pivot point in the course of the formation of Aboriginal contemporary music, through examining Lu Sen-bao’s works and the dissemination of his works, by means of discussions about “shoka” and “popular song.”
