The cultural legacy of mouth-blown flute and nose flute performances, which is the most representational musical instrument culture in Paiwanese music tradition, which reflects the feudal system, lifestyles, musical characteristics and craftsmanship of the Paiwan Tribal Group. Before Amendments to the Cultural Heritage Preservation Act were enacted in 2005, the National Center for Traditional Arts had contrived to preserve precious historic documents and create a human resource database through implementing “the plan for the preservation and transmission of folk arts (1995- 2003)” for this traditional art was on the verge of distinction. Whilst the Headquarters Administration of Cultural Heritage (HACH) was established, the authority has endeavored to support legal registration tasks and has continued to promote traditional arts. Over the past two decades the inheritance crisis of Paiwanese mouth-blown flute and nose flute culture has achieved some improvement under the combined influence of governmental action to preserve traditional music and the widespread awareness of aboriginal self-identity. This traditional art of the Paiwan Tribal Group, full of ethnical and cultural features and designated as a “significant traditional art” by the Council for Cultural Affairs (CCA), will be conserved and revitalized within HACH’S four-year phase of the project. By analyzing the official administration’s promotion of Paiwanese flute crafts, tribal endeavors in cultivation and prevalence of cultural heritage, as well as the adaptability and development of flute-performing culture, this article aims to provide reference material for follow-up measures on preservation/conservation management and cultural transmission.
