The author of the libretto of the Italian composer Amilcare Ponchielli’s opera “La Gioconda” is the well-known Italian composer and poet Arrigo Boito who wrote it under the pseudonym Tobia Gorrio. The plot is based on the drama "Angelo, Tyrant of Padua" by Victor Hugo. "La Gioconda" was premiered on April 8, 1876, in La Scala, Milan.

The authors of the libretto of Suppé's operetta are Friedrich Zell and Richard Genée. The plot is based on some novellas from the collection "Decameron" by Giovanni Boccaccio, which were masterfully united in such a way that the main character became Boccaccio himself.

The Italian libretto was written by Felice Romani on the basis of the tragedy "Norma, or the Infanticide" by French dramatist Louis Alexandre Soumet.  
Bellini completed the music for the opera 20 days before the premiere. At the request of the composer, the rehearsals also continued in the morning on the day before the premiere. Because of this, all the soloists were very tired, and as a result, the premiere that took place on December 26, 1831, failed. Bellini called this performance a "real fiasco." But on the next day, December 27, the audience appreciated the opera, applauding even during those scenes that had been especially poor on the previous evening. From that day on, Bellini’s "Norma" began its triumphal procession in the world's opera houses.

Czech composer Smetana began to write this satirical Opera in 1863. The author of the libretto was the famous Czech writer Karel Sabina. The initial version of the libretto written only for a single act did not satisfy the composer. At his request, the libretto was expanded to two acts. Smetana finished the music for this version in 1866. On May 30 of the same year, the Opera was premiered at the Provisional Theater in Prague. In 1870, Smetana changed the Opera to be presented in St. Petersburg. He partially modified the text of the Opera and created several new musical episodes. This new version consisted of three acts and continues to be presented to the audience in this form.

The plot of Tchaikovsky's ballet "Тhe Nutcracker" was borrowed from the tale  "The Nutcracker and the Mouse King" by Ernst Theodor Amadeus Hoffmann. But the libretto is based on the tale "The Story of the Nutcracker" by Alexander Dumas the Father (1844), which was wrongly attributed to Alexander Dumas the Son in the "Theatrical Encyclopedia." Tchaikovsky worked on the creation of the ballet with popular ballet master Marius Petipa. The premiere took place on December 6, 1892, at the Mariinsky Theater along with the Opera "Iolanta."
