This study investigates the revitalization of local music and performance traditions within a peri-urban community in Thailand following the profound disruption of the COVID-19 pandemic. Recognizing that global access and inevitable change challenge the preservation of Intangible Cultural Heritage (ICH), the work addresses a gap in understanding how transitional communities can leverage integrated strategies of cultural conservation and adaptation to foster resilience. The central theme explored is how music and performance serve as a bridge for collective expression, spiritual connection, and holistic community well-being.The research employed a Qualitative Participatory Action Research (PAR) methodology, involving artists, academics, and diverse community stakeholders in a dynamic cycle of co-creation. The primary aim was to analyze the integration of conservation (deliberate preservation of core traditions) and deconstruction (adaptive reimagining for contemporary relevance) to facilitate collaborative creativity.Key findings from the "Yu Yen Pen Suk Na Salaya" initiative, centered at a local religious and cultural hub, demonstrated the effectiveness of this integrated approach. Conservation efforts successfully maintained traditions such as Phleng Lae(chanting/singing), which reinforced spiritual and historical community linkages. Simultaneously, deconstruction was evidenced by the adaptation of Likay (folk theatre) and Phleng Ruea (boat songs) to disseminate public health knowledge, proving music's direct utility for community safety and communication during a crisis. The interdisciplinary "Kalpavriksha: Wishing Tree" project further utilized music and performance as symbolic, collective expression to promote social healing and instill hope (a spiritual element) in the post-pandemic recovery. This confirms that collaborative music activities directly mobilize cultural ecosystem services to enhance community well-being.In conclusion, this research establishes a replicable model for ICH revitalization in transitional contexts, demonstrating that music acts as a powerful bridge that connects tradition with contemporary societal needs. The study’s implications for music education and community practice emphasize the critical need to view cultural traditions as living, adaptable systems—not objects to be preserved—by actively empowering local practitioners and youth in continuous collective expression and adaptation, thereby strengthening long-term community resilience.
