This paper analysed the Great War’s impact upon musical internationalism. It did not deal with the reception or representation of particular composers. Instead, it considered cultural initiatives that explicitly affirmed music’s universal features – namely international exhibitions and congresses. Musical exhibitions and musicological congresses had already existed before the First World War; yet after 1914, they were subjected to broader ruptures within cultural and scientific internationalism. In tracing particular continuties from the fin de siecle to the interwar years, the paper focusd on three events that were held between 1927 and 1930: the international musical exhibition ‘Musik im Leben der Volker’ in Frankfurt, the International Congress of Popular Arts in Prague, and musical activities in the framework of the world’s fair of Liege and Antwerp.
