Italian opera revisited, history was retold and imagination was stimulated. The strength of it fell into a more violent era for opera: verismo, with "Cavalleria rusticana" by Pietro Mascagni and "Pagliacci" by Ruggero Leoncavallo. Some of the greatest Italian operas of the 20th century were written by Giacomo Puccini (1858–1924). These include "Manon Lescaut", "La bohème", "Tosca", "Madama Butterfly", "La fanciulla del West", "La rondine" and "Turandot", the last two being left unfinished. In 1926 and in 2002 Franco Alfano and Luciano Berio respectively attempted a completion of "Turandot", and in 1994 Lorenzo Ferrero completed the orchestration of the third version of
Verismo (music) earlier Italian opera. Instead, the operas were "through-composed," with few breaks in a seamlessly integrated sung text. While "verismo" operas may contain arias that can be sung as stand-alone pieces, they are generally written to arise naturally from their dramatic surroundings, and their structure is variable, being based on text that usually does not follow a regular strophic format. The most famous composers who created works in the "verismo" style were Giacomo Puccini, Pietro Mascagni, Ruggero Leoncavallo, Umberto Giordano and Francesco Cilea. There were, however, many other "veristi": Franco Alfano, Alfredo Catalani, Gustave Charpentier ("Louise"), Eugen d'Albert ("Tiefland"), Ignatz Waghalter
