Neapolitan Postcards gathers a diverse group of international scholars to investigate unexplored transnational aspects of the intimate yet globally popular canzone napoletana. Performed and beloved worldwide in almost every language, the style had hits such as “Funiculì funiculà” (1880) and “’O sole mio” (1898) which sold millions of copies. These hits fueled the tradition’s spread across the world over the course of the twentieth century with the eventual popularity of covers by singers and musicians of all music genres and styles, from popular music to opera and jazz. This book is the first scholarly work that considers the specific complexities of the international Neapolitan Song scenes through case studies from Argentina, England, Greece, and the United States, employing analyses of compositions, iconographical sources, international films, mechanical musical instruments, performances, and recordings devoted to the canzone napoletana.
