Gianni Schicchi
When "Il trittico" premiered at New York's Metropolitan Opera in December 1918, "Gianni Schicchi" became an immediate hit, whereas the other two operas were received with less enthusiasm. This pattern was broadly repeated at the Rome and London premieres and led to commercial pressures to abandon the less successful elements. Although on artistic grounds Puccini opposed performing the three operas except as the original triptych, by 1920 he had given his reluctant consent to separate performances. "Gianni Schicchi" has subsequently become the most-performed part of "Il trittico" and has been widely recorded.
