abstract: The focus of this in-depth study is to look at the gestation, performance history, and reception of Giacomo Puccini's evening of three one-act operas called Il Trittico and differentiate the particular components, Il Tabarro, Suor Angelica, and Gianni Schicchi to analyze them for their individual stylistic elements of Italian Opera. These were the styles of verismo, pathos and sentimentality, and opera buffa. As substantiated by written criticism, the audience and the critics did not fully comprehend the hidden meaning behind the individual works of Il Trittico. Puccini, enigmatically, had chosen to present one last glimpse of outmoded Italian operatic traditions. In order to evaluate Il Trittico's importance in the history of Italian opera, this study will first review the musically changing landscape in Italy during the early to mid-nineteenth century, then the second part of the nineteenth and beginning of the twentieth-century when German, French, and eventually Russian music were starting to influence audience taste. Puccini who, over the course of his compositional life, absorbed and incorporated these different styles realized that long held Italian operatic tradition had reached a fork in the road. One path would ensure Italian composers a place in this new order and the other a stagnant dead end. Even though Puccini's triptych garnered primarily negative reviews, the basis for this negativity was the perception that Il Trittico had broken with the historically traditional Italian musical styles. Though the present study acknowledges that break to a degree, it will also present a historically based rationale for the deviation, one left largely unnoticed by Puccini's critics. In the end, this author plans to realize their symbolic importance as a farewell to three uniquely Italian styles and a departure point for a new operatic tradition. Looking forward to the centenary of the work, this author seeks to illuminate how Puccini reached the pinnacle of firmly rooted genres of Italian opera. Ultimately this might help to unravel the enigma of Il Trittico while it continues to secure its rightful place as one of the masterpieces of the Puccini canon. / Dissertation/Thesis / Masters Thesis Music 2015
