Pauline Duchambge née de Montet (1778 – 23 April 1858) was a French Creole pianist, singer, and composer.
 Duchambdge (Montet) was born in Martinique, West Indies and was the daughter of a noble family.
 She was taken to Paris, where she received a convent education and studied the piano from composer and author Jean Baptiste Desormery, son of the famous comic opera actor and composer Léopold-Bastien Desormery.
 Pauline composed and performed as a singer and a pianist.
 She studied harmony and composition with Daniel Auber and with Luigi Cherubini, who wrote several compositions for her.
 She also studied piano and composition with Jan Ladislav Dussek.
 Pauline left the convent in 1792 and married Baron Duchambge in 1796.
 In 1798 at the age of 20, she lost both her parents and with them the family fortune.
 Soon afterwards she was later divorced.
 It was after these events that Duchamge musical education began in earnest.
 She studied church music with Jan Dussek, Luigi Cherubini and D.F.E Auber.
 In 1815, Duchambge met the French poet and novelist, Marceline Desbordes-Valmore beginning a lifelong friendship and collaboration.
 Their friendship is documented by a lengthy correspondence and a number of songs by Duchambge on Debordes-Valmore’s texts including L’adieu tout bas, La fiancée del marin, Je pense à lui, La jeune Châtelaine, Rêve du mousse, La sincère and La valse et l’automne.
 Duchambge also composed music to texts and romances of other female authors such as Mme Amble Tastu and Mme Emile De Girardin.
 Pauline Duchambge wrote over three hundred romances, a very popular genre in the nineteenth century.
 Auber deposited three hundred of Duchambge’s songs in the Bibliothèque du Conservatoire in Paris.
 Eleven of Duchambge's individual songs and albums of songs were published between 1827 and 1841 by some of the leading Parisian publishers: Jean Antoine Meissonnier, Jacques-Joseph Frey, A. Petibon, and Ignace Pleyel.
 Her works reached a German audience through the Berlin publisher Maurice Schlesinger and the Schott firm in Mainz.
 In addition to songs, Duchambge wrote a few piano pieces.
 Duchambge had a difficult life, struggling with poverty, delicate health, and the disenchantments of love; her music expresses her emotions.
 She commented: "Love, it is life!
 but a life full of troubles, illusions, deceptions, repentance, discouragements…. "
Destiny (also known as "Fate", Czech: "Osud" ) is an opera in three acts by Leoš Janáček to a Czech libretto by the composer and Fedora Bartošová.
 Janáček began the work in 1903 and completed it in 1907.
 The inspiration for the opera came from a visit by Janáček in the summer of 1903, after the death of his daughter Olga, to the spa at Luhačovice.
 There, Janáček met Kamila Urválková, who had been the subject of an opera by Ludvík Čelanský, "Kamila", where she felt that Čelanský had falsely depicted her personality.
 After learning that Janáček was a composer, Urválková persuaded Janáček to write another opera to counteract Čelanský's portrait of her.
Luigi Cherubini (] ; 8 or 14 September 1760 – 15 March 1842) was an Italian composer who spent most of his working life in France.
 His most significant compositions are operas and sacred music.
 Beethoven regarded Cherubini as the greatest of his contemporaries.
Leoš Firkušný was a Czech musicologist.
 He was born on July 16, 1905 in Napajedla (today's Czech Republic).
 He was an older brother of the famous pianist Rudolf Firkušný.
 He was an expert on Leoš Janáček and did much to bring his music to the listeners abroad.
 He was one of the founders of the music festival Prague Spring.
 He died on July 9, 1950 in Buenos Aires, Argentina.
Leoš Janáček (] , baptised Leo Eugen Janáček; 3 July 1854 – 12 August 1928) was a Czech composer, musical theorist, folklorist, publicist and teacher.
 He was inspired by Moravian and other Slavic folk music to create an original, modern musical style.
The Leoš Janáček International Competition in Brno (hereinafter referred to as MSLJ) (Czech: Mezinárodní soutěž Leoše Janáčka v Brně ) is a music competition held annually by the Faculty of Music of the Janáček Academy of Music and Performing Arts Brno.
 The MSLJ was named after the famous composer Leoš Janáček.
Káťa Kabanová (also known in various spellings including "Katia", "Katja", "Katya", and "Kabanowa") is an opera in three acts, with music by Leoš Janáček to a libretto by , based on "The Storm", a play by Alexander Ostrovsky.
 The opera was also largely inspired by Janáček's love for Kamila Stösslová.
 This is often considered his first "mature" opera, despite the fact that he was 67 when it was premiered.
 "Káťa Kabanová" is a clear response to Janáček's feelings for Kamila, and the work is dedicated to her.
 The first performance was at the National Theatre (Národní divadlo v Brně ) in Brno on 23 November 1921.
The Overture in G major by Luigi Cherubini (1760-1842) is an orchestral work written for concert use in early 1815.
 It is unusual among Cherubini's overtures in that his other, better known overtures (such as those to "Anacreon", "Médée", "Les deux journées" and "Ali Baba"), were intended to introduce stage works.
 Although born in Italy Cherubini had been living in France since 1784, and had earned world fame through a series of operas composed for the Paris stage.
 In the first decade of the nineteenth century the vogue for his dramatic works began to wane, and he turned increasingly to sacred music.
Janáček is a crater on Mercury.
 It has a diameter of 47 kilometers.
 Its name was adopted by the International Astronomical Union in 1985.
 Janáček is named for the Czech composer Leoš Janáček, who lived from 1854 to 1928.
The Sinfonietta (subtitled “Military Sinfonietta” or “Sokol Festival”) is a very expressive and festive, late work for large orchestra (of which 25 are brass players) by the Czech composer Leoš Janáček.
 It is dedicated “To the Czechoslovak Army” and Janáček said it was intended to express “contemporary free man, his spiritual beauty and joy, his strength, courage and determination to fight for victory.”
 It started by Janáček listening to a brass band, becoming inspired to write some fanfares of his own.
 When the organisers of the Sokol Gymnastic Festival approached him for a commission, he developed the material into the "Sinfonietta".
 He later dropped the word "military".
 The first performance was in Prague on 26 June 1926 under Václav Talich.
 Typical performance duration is 20–25 minutes.
