Question: Who wrote comic opera, Gianni Schicchi, which features the soprano aria sung by Lauretta?

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. <SEP>  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. "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 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. <SEP> An insertion aria (also known as interpolated aria, trunk aria, or aria di baule in Italian) is an aria sung in an opera for which it was not composed.  It was a practice that began in the seventeenth century and continued actively through the late 19th century and sporadically through the 20th century.  The insertion aria could replace an existing aria, or might be added to an opera.  All insertions were planned in advance.  They might be composed by the same composer of the opera, or might have been written by a different composer, with or without the knowledge of the opera's composer.  Most insertions were of arias; infrequently non-operatic songs were inserted.  Insertions could consist of arias, duets, ensembles, even entire scenes.  Although men and women singers used insertion, women are the ones most remembered for the practice.  The years 1800–1840 represent the apex of influence that women singers exerted over the operatic stage, influencing most aspects of opera performances, including insertions. <SEP> Anna Nechaeva is Russian soprano singer who was born in Saratov and used attend its Conservatory in 1996.
