Pietro Antonio Stefano Mascagni (December 7, 1863 – August 2, 1945) was an Italian composer most noted for his operas.
Mascagni’s 1890 masterpiece Cavalleria Rusticana caused one of the greatest sensations in opera history and single-handedly ushered in the Verismo movement in Italian dramatic music. While it was often held that Mascagni, like Leoncavallo, was a “one-opera man” who could never repeat his first success, L’amico Fritz and Iris have remained in the repertoire in Europe (especially Italy) since their premieres. Mascagni said that at one point, Iris was performed in Italy more often than Cavalleria (cf. Stivender).
