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.

 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.

 The first performance was at the National Theatre (Národní divadlo v Brně ) in Brno on 23 November 1921.
Leoš Janáček (] , baptised Leo Eugen Janáček; 3 July 1854 – 12 August 1928) was a Czech composer, musical theorist, folklorist, publicist and teacher.

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.
