Coastal landscapes inspire their own genre of folk songs and musical instruments intrinsic to the traditions of the local boat people and fisherfolk, often coexisting with a strand of popular music embedded within the modalities of coastal tourism. In post-colonial coastal cities, these strands are part of a larger musical space carved out by the legacies of colonial cultural transmission and subsequent assimilation into aspirational European cosmopolitan tropes. I examine the shifting engagement of Western classical choirs in the context of two coastal cities: Goa in India and Colombo (with a focus on Negombo) in Sri Lanka. Combining in-depth interviews with two choral conductors alongside the predicament of musical production in the digital space, I argue that choral music impinges on a notion of personal intimacy that combines a collective sense of creativity and community, organically linked to Catholic landscapes animated by a ‘Catholic affect’.
