The traditional lifestyles of Taiwan’s indigenous peoples have been greatly influenced due to excessive urbanization. Because of this backdrop, their purely primitive musical styles are gradually disappearing. “Pasi but but” (“Prayer for the Millet Harvest”), a traditional song of Taiwan Bunun Tribe, is performed with a unique musical style called “eight-part harmonic singing”. “Pasi but but” means “lift up each other” in Bunun language, now it has a derivational meaning, “lift up the tone clusters together.” This work is “interactive installation”, involving music, visual images and the performance. In this way, different tones are simultaneously held. The participants can move their bodies respectively to change the volume of each tone. Their positions vary from high to low, according to the volume, along with the projected visual images.

This thesis attempts to probe into the definition, characteristics and the main idea of Interactive Art from the perspective of Total Artwork, to discuss issues about shifting of authorship, the concept of the game, the trend of multimedia and interdisciplinary practice, aesthetics and related works, and finally to comprehensively present the whole idea to create this work, the process and the conclusion. In doing so, not only can this interactive performance reflect the original linguistic meaning of “pasi but but”, but it also can hopefully draw public attention to the fact that primitive musical styles are gradually disappearing.
