Music education serves as a powerful medium for building bridges across cultures, abilities, and generations. This practice-based research investigates Kolintang, a traditional ensemble from North Sulawesi, Indonesia, recently recognized by UNESCO as Intangible Cultural Heritage, as both a cultural resource and an innovative pedagogical framework. Drawing from the author's role as a Deaf researcher, educator, and performer, the study introduces Kalisarmonia, an embodied cognition model where the human body functions as a musical instrument through mapped tonal gestures. This approach extends Kolintang pedagogy into a multisensory system integrating spatial awareness, mathematics, and accessible music-making.The research addresses a persistent challenge: music education often marginalizes participants with disabilities, particularly Deaf and hard-of-hearing students, and rarely integrates heritage instruments into global pedagogical discourse. By situating Kolintang within inclusive and transcultural frameworks, this research highlights how indigenous traditions can generate universal tools for unity in music education.Methodologically, the study combines ethnographic inquiry, inclusive design, and practice-based experimentation. Workshops were conducted in schools, community centers, and church-based settings, engaging children, university students, and mixed-ability participants. Tools included body percussion, “Kolintang Hand” embodied mapping, and Directional Chord Symbols to support haptic and visual learning. Data collection involved observations, participant reflections, and small focus groups. Analysis employed a thematic approach Braun and Clarke (2006) to identify patterns of inclusion, embodied learning, and cultural meaning-making.Preliminary findings suggest three key outcomes: (1) Deaf participants engaged actively through bodily movement and haptic cues, demonstrating new modes of musical participation; (2) children developed mathematical and spatial understanding through embodied Kolintang exercises, linking rhythm and vector patterns to STEM concepts; (3) Kolintang operated as a cultural bridge, connecting local traditions with global educational practices. These outcomes resonate with broader debates on inclusive pedagogy, demonstrating how heritage-based frameworks can complement or even surpass technology-driven approaches to accessibility.The paper concludes that Kolintang and Kalisarmonia together represent an emergent model of inclusive music pedagogy. While the study is limited in scale, it underscores the potential of indigenous instruments as catalysts for intercultural empathy, identity formation, and equitable access to music learning. By reframing Kolintang not only as cultural heritage but also as a contemporary educational resource, this research contributes directly to ISME’s vision of “Unity in Music Education: Building Bridges for All.”
