Because opera is written in any and every musical key, you can find an opera or an aria in any key you want.
Puccini had 6 siblings, He was one of seven children of Michele Puccini and Albina Magi. Puccini was an Italian composer whose operas are among the important operas played as standards.
It was published by G. Ricordi & Co. Any good music shop should be able to get it for you. On line you could try the Juilliard Store. They have tons of sheet music.
Franz Liszt was for sure no opera composer. He only completed one, "Don Sanche", when he was 13 years old, and it was a failure. He attempted to write more operas later in his life, but never finished any.
I'm pretty sure opera can be sung in any language, but most times its sung in Italian French or German
There have been a few operas that have been written in English, but the majority by far of them have been written in other languages, most notably Italian.
Within this context -- any Verdi opera would be considered a classical opera.
In Puccini's opera La Rondine there is a party sequence in which a concert pianist performs, s/he also plays the opening measures of the famous aria "Doretta's Beautiful Dream." There may well be other examples, but this is what first comes to mind.
Basically as any composer would, however in the case of this opera the way his writing complements and supports each other is exceptionally well done and if you were to take particular note the music always 'sets the scene' without being overly intrusive. I think that possibly one of the best examples is in act 1 from 'Your tiny hand is frozen' to the very end of the act.
I think I can answer my own question. Andrew Lloyd Webber was sued by the Puccini estate for plagiarizing this melody and settled out of court. Apparently Lerner and Lowe may also have plagiarized it.
The New Grove Dictionary of Opera considers La Cilla(music by Michelangelo Faggioli, text by F. A. Tullio, 1706) to be the first genuine opera buffa; but the term refers to any Italian comic opera written approximately between that date and 1850, so it's probably not possible to be sure which was the very first.
Bach never composed any opera's. He did compose cantata's, however.
