--- - |2 Abstract Although the relationship between music and nationalism has been at the centre of recent cross‐disciplinary research, many areas remain unexplored. Among them are forms of ‘national music’ that nest overlapping identities, functioning simultaneously as vehicles of regional, ethnic, urban, global and diasporic belongings. This article focuses on the national dimension of these multilevel identities, concentrating on the swings and transmigrations between the national and the regional. It compares two Mediterranean traditions which, particularly between the late nineteenth and early twentieth centuries, have served as multilevel identifiers of national and regional belongings: flamenco and canzone napoletana (Neapolitan song). I argue that, besides geographically bounded identities, both genres were constructed as ‘national’ primarily abroad, rather than in their home countries, thus contributing to a theory of the ‘international’ dimension of ‘national’ music. In the case of flamenco, I focus on the irradiation centre of the time, Paris, although the modern notion of musical Spanishness was first associated with national identity in Russia. The canzone consolidated its international position mostly through the Italian diaspora, achieving a much wider reach than is ordinarily thought, both nationally and globally. - Nations and Nationalism, Volume 24, Issue 3, Page 669-694, July 2018.
