Cross-Cultural Music: Integrating Thai Music And Western Guitar For Learning And Sustainability: A Case Study Of Stephen Goss's Sonata Capriccioso

This study examines how Stephen Goss’s Sonata Capriccioso (2015) for solo guitar establishes a cross-cultural dialogue between Western classical guitar techniques and Thai musical aesthetics. Using detailed score analysis and the composer’s program notes, the research identifies key integrative mechanisms: character-based formal innovation in the first movement (Allegro scherzando) , the incorporation of Thai instrumental techniques such as uean and sa-bat with pentatonic scales in the second movement (Idyll) , and perceived temporal changes in the finale (Moto perpetuo) achieved through frequent meter shifts , reflecting Thai concepts of augmentation and diminution. This study further situates this cross-cultural approach within the framework of sustainable development. It supports SDG 4: Quality Education by fostering creative skills and cultural knowledge , SDG 8: Decent Work and Economic Growth by promoting opportunities in performing arts and music production , and SDG 11: Sustainable Cities and Communities by preserving cultural heritage and strengthening community identity. The findings demonstrate that music and culture are not only expressions of national identity but also practical tools for advancing sustainability across educational, economic, and social domains.
