Introduction to Tosca;

1800, Mario Kabala Dorsey, a Roman painter, was arrested and punished for sheltering Angelaud, a political prisoner, and the opera actress Tosca fell in love with him. Scarpia, the police chief, was fascinated by Tosca and promised to release her lover. In return, she must entrust herself to him. Tosca was forced to pretend to obey, and just after the police chief wrote the order of fake execution, he stabbed him to death without a spare knife. At dawn, Mario was taken to the execution ground, and Tosca told him that it was just a fake execution. Unexpectedly, this was a trick played by the police chief, and Mario was really executed. At this time, the assassination of the director has been discovered, and it is believed that Scarpia was killed by Tosca. Tosca was desperate, and finally shouted "Scarpia, see you before God" and committed suicide by jumping off the wall.

Tosca is Puccini's opera. Three acts. It was made in 1900 and premiered in Rome in the same year. The play was adapted from Sardo's play by Jacques and Ilica. In this opera, Puccini pays attention to the emotional rendering and dramatic effect of music. The whole play always emphasizes the importance of vocal music, and there are many wonderful arias. For example, in the second act, Tosca's aria is for art and love. The stars gather in the third act of Kabala Dorsey's aria. The characters in the play are deeply shaped and have strong artistic appeal.
