The Introduction outlines the theoretical framework, starting with a review of the existing literature on musical modernism, global musicology and related theories, including discussions of universalism, methodological nationalism, the centre versus periphery paradigm, multiple modernities, hybridity and postcolonial and decolonising approaches. It further introduces the interdisciplinary concept of ‘entangled histories’, which is illustrated with three short cases studies: the Orchesta Experimental de Instrumentos Nativos (OEIN) from Bolivia, the Bow Project from South Africa and Uwalmassa, a trio creating ‘deconstructed gamelan music’ from Jakarta, Indonesia. What unites these cases is that they are rooted in local traditions, rather than on the adoption or imposition of Western practices, although they undoubtedly respond creatively to Western ideas.
