Bernardo de Muro debuted in performing in "Cavalleria rusticana" by the Italian composer who ushered in which movement?
Pietro Mascagni Pietro Antonio Stefano Mascagni (] ; 7 December 1863 – 2 August 1945) was an Italian composer most noted for his operas. His 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).
Giovanni Battista Sammartini Giovanni Battista Sammartini (c. 1700 – 15 January 1775) was an Italian composer, oboist, organist, choirmaster and teacher. He counted Gluck among his students, and was highly regarded by younger composers including Johann Christian Bach. It has also been noted that many stylizations in Joseph Haydn's compositions are similar to those of Sammartini, although Haydn denied any such influence. Sammartini is especially associated with the formation of the concert symphony through both the shift from a brief opera-overture style and the introduction of a new seriousness and use of thematic development that prefigure Haydn and Mozart. Some of his works are described as "galant", a style associated with Enlightenment ideals, while "the prevailing impression left by Sammartini's work... [is that] he contributed greatly to the development of a Classical style that achieved its moment of greatest clarity precisely when his long, active life was approaching its end".
