The chapter illuminates diverse musical encounters or engagements between ‘minority’ cultures and what was, until recently, an Anglo-Australian majority over four periods of social, cultural and political foment between the pre-Federation colonial era and the present. It first examines the pre-WWI musical contributions of German-speaking residents and visitors, and Italian and Jewish influence on musical entertainment in the inter-war and post-war era. It then considers how, from the 1980s, the twin forces of local multiculturalism and ‘world music’ intersected in Australia to foster a wealth of musical diversity, including creative musical interventions and experimentations. We also consider the many multi-faceted present-day music ‘scenes’ associated with diasporic communities by honing into the local world of Indonesia-related music-making in Australia. Music of minority cultures tends to become articulated through uneven power relationships with the majority culture and its institutions, but the chapter provides a more nuanced view of this relationship. It demonstrates, for example, how ‘minority’ musicians have strategically deployed the ‘power’, or value, of ‘difference’ for professional or other advantage, exploiting opportunities provided by the mainstream, which can simultaneously shape and even redefine minority music.
