Norma is a female name.
 A single instance of the name "Norma" is recorded 1203, where it perhaps derives from the Latin word "norma", meaning "precept".
 The name's general usage seems to be subsequent to the 1831 debut of Vincenzo Bellini's opera "Norma" whose librettist Felice Romani borrowed the name (and the plot) from the recent tragedy "Norma" by Alexandre Soumet.
 Soumet's choice of name for his title character may possibly have been influenced by the name of the Germanic mythological Norns.
 More recently "Norma" has been used as a female equivalent of the name "Norman", meaning "Norseman".
Vincenzo Negrini (born Vincenzo Bartolomeo Trentanove) (24 August 1804 – 16 August 1840) was an Italian bass-baritone opera singer.
 Born in Cesena, he sang leading bass and baritone roles in Italy's major opera houses and created several roles in early 19th-century operas, most notably Oroveso in Bellini's "Norma" and Folco in Donizetti's "Ugo, conte di Parigi".
 Severe heart disease caused him to retire from the stage in June 1840.
 He died in Milan two months later at the age of 35.
Norma (] ) is a "tragedia lirica" or opera in two acts by Vincenzo Bellini with libretto by Felice Romani after "Norma, ou L'infanticide" ("Norma, or The Infanticide") by Alexandre Soumet.

Rossini had influenced the management of the Théâtre-Italien to commission works by the outstanding Italian composers of the day—Donizetti and Vincenzo Bellini.
 Both wrote operas for that house in Paris, Bellini's contribution being the hugely-successful "I puritani".
 Donizetti's opera, which premiered on 12 March 1835 (a few months after "I puritani") was not nearly as much of a success.
 However, it marked Donizetti's first opera to have its premiere in Paris.
"Vaga luna, che inargenti " (Beautiful moon, dappling with silver) is an arietta composed by Vincenzo Bellini to an anonymous Italian text and dedicated to Giulietta Pezzi.
 It was published in 1838 by Casa Ricordi in "Tre ariette inedite " along with two other Bellini songs, "Il fervido desiderio " and "Dolente immagine di Fille mia ".
 It was also amongst the fifteen Bellini songs published by Ricordi under the title "Composizioni da Camera " in 1935, the centenary of the composer's death.
 Composed in the bel canto style, it is a frequent recital piece, and has often been recorded.
 Its original key is in A-flat major with a tempo of andante cantabile.
