Context: Suor Angelica (Sister Angelica) is an opera in one act by Giacomo Puccini to an original Italian libretto by Giovacchino Forzano.  It is the second opera of the trio of operas known as "Il trittico" ("Triptych").  It received its world premiere at the Metropolitan Opera on December 14, 1918. Il trittico ("The Triptych") is the title of a collection of three one-act operas, "Il tabarro", "Suor Angelica", and "Gianni Schicchi", by Giacomo Puccini.  The work received its world premiere at the Metropolitan Opera on 14 December 1918. Gianni Schicchi (] ) is a comic opera in one act by Giacomo Puccini to an Italian libretto by Giovacchino Forzano, composed in 1917–18.  The libretto is based on an incident mentioned in Dante's "Divine Comedy".  The work is the third and final part of Puccini's "Il trittico" (The Triptych)—three one-act operas with contrasting themes, originally written to be presented together.  Although it continues to be performed with one or both of the other "trittico" operas, "Gianni Schicchi" is now more frequently staged either alone or with short operas by other composers.  The aria "O mio babbino caro" is one of Puccini's best known, and one of the most popular arias in opera. Giuseppe De Luca (25 December 1876 – 26 August 1950), was an Italian baritone who achieved his greatest triumphs at the Metropolitan Opera in New York City.

Later she was offered to perform the role of "Tatiana" in "Eugene Onegin" at the Saint Petersburg Conservatory and by 2003 became a soloist at the Saint Petersburg Opera where she continued her original role as well as other title roles in Giacomo Puccini's "Gianni Schicchi", Madama Butterfly, and "Suor Angelica".  From 2008 to 2011 she became a soloist at the Mikhaylovsky Theatre where she performed roles of "Nedda" in "Pagliacci" and "Rachel" in "The Jews" as well as the title roles of "Rusalka" and of course "Tatiana" in "Eugene Onegin".  In 2012, she made her first public appearance with Bolshoi Theatre where she sang in "The Enchantress" portraying "Nastasya" becoming soloist there the same year.  After her debut, she performed such roles as "Iolanta" in an opera of the same name as well as "Liu" in "Turandot" and "Yaroslavna" in "Prince Igor". "O mio babbino caro " ("Oh My Beloved Father") is a soprano aria from the opera "Gianni Schicchi" (1918) by Giacomo Puccini to a libretto by Giovacchino Forzano.  It is sung by Lauretta after tensions between her father Schicchi and the family of Rinuccio, the boy she loves, have reached a breaking point that threatens to separate her from Rinuccio.  It provides an interlude expressing lyrical simplicity and single-hearted love in contrast with the atmosphere of hypocrisy, jealousy, double-dealing, and feuding in the medieval Florence of Puccini's only comedy.  It provides the only set-piece in the through-composed opera. Giovacchino Forzano (] ; 19 November 1884 – 28 October 1970) was an Italian playwright, librettist, stage director, and film director.

He remained at the Opéra Comique for three years, portraying a variety of roles like, Basilio in "The Barber of Seville", the title role in Giacomo Puccini's "Gianni Schicchi", the Prior in Massenet's "Le Jongleur de Notre Dame", de Grieux in "Manon", Lothario in "Mignon", Ramon in Charles Gounod's "Mireille", the four villains in "The Tales of Hoffmann", Count Almaviva in "Le nozze di Figaro", and Scarpia in "Tosca" among others.

The three were premiered at the Metropolitan Opera on 14 December 1918, and for the next three years were always played together.  After 1921, however, Puccini agreed that the operas could be performed separately. " Gianni Schicchi" became the most popular and most frequently performed of the three, often paired with other works such as Maurice Ravel's "L'heure espagnole" and Richard Strauss's "Salome".
