The Symphony in C is an early work by the French composer Georges Bizet.
 According to "Grove's Dictionary", the symphony "reveals an extraordinarily accomplished talent for a 17-year-old student, in melodic invention, thematic handling and orchestration."
 Bizet started work on the symphony in C major on 29 October 1855, four days after turning 17, and finished it roughly a month later.
 It was written while he was studying at the Paris Conservatoire under the composer Charles Gounod, and was evidently a student assignment.
 Bizet showed no apparent interest in having it performed or published, and the piece was never played in his lifetime.
 He used certain material from the symphony in later works, however.
 There is no mention of the work in Bizet's letters, and it was unknown to his earlier biographers.
 His widow, Geneviève Halévy (1849–1926), gave the manuscript to Reynaldo Hahn, who left it along with other papers to the archives of the conservatory library, where it was found in 1933 by Jean Chantavoine.
 Soon thereafter, Bizet's first British biographer Douglas Charles Parker (1885–1970) showed the manuscript to the conductor Felix Weingartner, who led the first performance in Basel, Switzerland, on 26 February 1935.
Georges Bizet (] ; 25 October 18383 June 1875), registered at birth as Alexandre César Léopold Bizet, was a French composer of the romantic era.
 Best known for his operas in a career cut short by his early death, Bizet achieved few successes before his final work, "Carmen", which has become one of the most popular and frequently performed works in the entire opera repertoire.
Bedřich Smetana (] ; 2 March 1824 – 12 May 1884) was a Czech composer who pioneered the development of a musical style which became closely identified with his country's aspirations to independent statehood.
 He is thus widely regarded in his homeland as the father of Czech music.
 Internationally he is best known for his opera "The Bartered Bride" and for the symphonic cycle "Má vlast" ("My Homeland"), which portrays the history, legends and landscape of the composer's native land.
Viola is an unfinished romantic opera by Bedřich Smetana.
 The libretto was written by Eliška Krásnohorská, and is based on Shakespeare's play "Twelfth Night".
 The composer did some work on it in 1874 and then came back to it in 1883, when he only managed to orchestrate a few scenes; the opera was left incomplete upon Smetana's death in 1884.
Smetana often refers to the Czech composer Bedřich Smetana.
   is a '"festival opera" in three acts, with music by Bedřich Smetana.
 The libretto was originally written in German by Josef Wenzig, and was then translated into Czech by Ervin Špindler.
 In Czech historical myth, Libuše, the title character, prophesied the founding of Prague.
 The opera was composed in 1871–72 for the coronation of Franz Josef as Czech king.
 This did not happen and Smetana saved "Libuše" for the opening of the National Theatre in Prague, which took place nine years later on 11 June 1881.
 After the destruction of the National Theatre in a fire, the same opera opened the reconstructed theatre in 1883.
 The first US performance was reported to have occurred March 1986, in a concert version at Carnegie Hall with Eve Queler and the Opera Orchestra of New York.

 It is situated in the centre of Prague in a small block of buildings right next to Charles Bridge on the right bank of the river Vltava in the Old Town (Novotného lávka 1, 110 00 Praha 1).
