<P0-S0> Loretta Di Franco is an American operatic soprano who is chiefly known for her more than 900 performances at the Metropolitan Opera from 1961-1995. <P0-S1>  Originally a member of the Met's opera chorus, she eventually was promoted to singing small comprimario roles beginning with one of the pages in Wagner's "Tannhäuser" and the peasant girl in "The Marriage of Figaro" in 1961. <P0-S2>  She went on to win the Metropolitan Opera National Council Auditions in 1965 which led to her first substantial role, Chloe in "The Queen of Spades". <P0-S3>  She continued to appear annually at the Met for the next 30 years, performing both leading and supporting roles. <P0-S4>  Some of the parts she performed at the Met included Annina in "La traviata", both the Aunt and Barena in Janáček's "Jenůfa", Barbarina and Marcellina in "The Marriage of Figaro", Berta in "The Barber of Seville", Countess Ceprano in "Rigoletto", the Dew Fairy and the Sandman in "Hansel and Gretel", Feklusa in "Káťa Kabanová", the First Lady in "The Magic Flute", the Flower Seller in Britten's "Death in Venice", Frasquita in "Carmen", Gerhilde in "Die Walküre", Giannetta in "L'elisir d'amore", Helen in "Mourning Becomes Electra", Ines in "Il trovatore", Jouvenot in "Adriana Lecouvreur", Kate Pinkerton in "Madama Butterfly", Laura in "Luisa Miller", Lauretta in "Gianni Schichi", Lisa in "La sonnambula", Marianne in "Der Rosenkavalier", Marthe in "Faust", Musetta in "La bohème", Oscar in "Un ballo in maschera", Samaritana in "Francesca da Rimini", Woglinde in both "Das Rheingold" and "Götterdämmerung", Xenia in "Boris Godunov", Zerlina in "Don Giovanni", and title role in "Lucia di Lammermoor". <P0-S5>  In 1991 she created the role of the Woman with Child in the world premiere of John Corigliano's "The Ghosts of Versailles". <SEP> <P1-S0>  Described as a "Große komische Oper ", it was composed in 1834, and Wagner conducted the premiere in 1836 at Magdeburg. <P1-S1>  Poorly attended and with a lead singer who forgot the words and had to improvise, it was a resounding flop and its second performance had to be cancelled after a fist-fight between the prima donna's husband and the lead tenor broke out backstage before the curtain had even risen; only three people were in the audience. <P1-S2> Das Liebesverbot ("The Ban on Love", WWV 38), is an early opera in two acts by Richard Wagner, with the libretto written by the composer after Shakespeare's "Measure for Measure". <P1-S3>  It was never performed again in Wagner's lifetime. <SEP> <P2-S0> The Bride of Lammermoor is an historical novel by Sir Walter Scott, published in 1819. <P2-S1>  The novel is set in the Lammermuir Hills of south-east Scotland, and tells of a tragic love affair between young Lucy Ashton and her family's enemy Edgar Ravenswood. <P2-S2>  Scott indicated the plot was based on an actual incident. <P2-S3>  "The Bride of Lammermoor" and "A Legend of Montrose" were published together as the third of Scott's "Tales of My Landlord" series. <P2-S4>  As with all the Waverley Novels, "The Bride of Lammermuir" was published anonymously. <P2-S5>  The novel claims that the story was an oral tradition, collected by one "Peter Pattieson", and subsequently published by "Jedediah Cleishbotham". <P2-S6>  The 1830 "Waverley edition" includes an introduction by Scott, discussing his actual sources. <P2-S7>  The later edition also changes the date of the events: the first edition sets the story in the 17th century; the 1830 edition sets it in the reign of Queen Anne, after the 1707 Acts of Union which joined Scotland and England. <P2-S8>  The story is the basis for Donizetti's 1835 opera "Lucia di Lammermoor". <SEP> <P3-S0>  Salvadore Cammarano wrote the Italian-language libretto loosely based upon Sir Walter Scott's historical novel "The Bride of Lammermoor". <P3-S1> Lucia di Lammermoor is a "dramma tragico" (tragic opera) in three acts by Gaetano Donizetti.
