Question: What profession does Emmanuel Chabrier and Leoš Janáček have in common?

full_context: Document 1: The Rite of Spring: The Rite of Spring (French: Le Sacre du printemps ; Весна священная, "Vesna svyashchennaya", "sacred spring" ) is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. It was written for the 1913 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Vaslav Nijinsky, with stage designs and costumes by Nicholas Roerich. When first performed, at the Théâtre des Champs-Élysées on 29 May 1913, the avant-garde nature of the music and choreography caused a sensation and a near-riot in the audience. Although designed as a work for the stage, with specific passages accompanying characters and action, the music achieved equal if not greater recognition as a concert piece, and is widely considered to be one of the most influential musical works of the 20th century.
Document 2: Léo Delibes: Clément Philibert Léo Delibes (] ; 21 February 1836 – 16 January 1891) was a French composer of the Romantic era (1815–1910), who specialised in ballets, operas, and other works for the stage. His most notable works include the ballets "Coppélia" (1870) and "Sylvia" (1876), as well as the operas "Le roi l'a dit" (1873) and "Lakmé" (1883).
Document 3: Maurice Ravel: Joseph Maurice Ravel (] ; 7 March 1875 – 28 December 1937) was a French composer, pianist and conductor. He is often associated with impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term. In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer.
Document 4: Claude Debussy: Achille-Claude Debussy (] , 22 August 1862 – 25 March 1918), known since the 1890s as Claude-Achille Debussy or Claude Debussy, was a French composer. He and Maurice Ravel were the most prominent figures associated with Impressionist music, though Debussy disliked the term when applied to his compositions. He was made Chevalier of the Legion of Honour in 1903. He was among the most influential composers of the late 19th and early 20th centuries, and his use of non-traditional scales and chromaticism influenced many composers who followed.
Document 5: Emmanuel Chabrier: Alexis Emmanuel Chabrier (] ; January 18, 1841September 13, 1894) was a French Romantic composer and pianist. Although known primarily for two of his orchestral works, "España" and "Joyeuse marche", he left an important corpus of operas (including "L'étoile"), songs, and piano music. He was admired by composers as diverse as Debussy, Ravel, Richard Strauss, Satie, Schmitt, Stravinsky, and the group of composers known as Les six. Stravinsky alluded to "España" in his ballet "Petrushka"; Gustav Mahler called "España" "the beginnings of modern music" and alluded to the "Dance Villageoise" in the "Rondo Burleske" movement of his Ninth Symphony. Ravel wrote that the opening bars of "Le roi malgré lui" changed the course of harmony in France, Poulenc wrote a biography of the composer, and Richard Strauss conducted the first staged performance of Chabrier's incomplete opera "Briséïs".
Document 6: Violin Sonata (Janáček): Violin Sonata, a composition for violin and piano, is a work of the Czech composer Leoš Janáček (1854-1928). It was written in the summer of 1914, but it was not Janáček’s first attempt to create such a composition. He resolved to compose a violin sonata already as a student at the conservatoire in Leipzig in 1880, and later during his studies in Vienna. His early sonatas are today lost.
Document 7: Petrushka (ballet): Petrushka (French: "Pétrouchka" ; Russian: "Петрушка" ) is a ballet burlesque in four scenes. It was composed in 1910–11 and revised in 1947. Igor Stravinsky composed the music, and, with Alexandre Benois, fashioned the libretto. Michel Fokine choreographed the ballet; Benois designed the sets and costumes. "Petrushka" was first performed by Sergei Diaghilev's Ballets Russes at the Théâtre du Châtelet in Paris on 13 June 1911. Vaslav Nijinsky portrayed Petrushka with Tamara Karsavina as the Ballerina. Alexander Orlov portrayed the Moor, and Enrico Cecchetti the Charlatan.
Document 8: Little Symphony No. 1 (Milhaud): Little (Chamber) Symphony No. 1 “Le Printemps” Op. 43, as the first of a collection of six “Little Symphonies,” by Darius Milhaud is a symphony by name, due to its length of just over 3 minutes. This piece should not be confused with Milhaud's Symphony No. 1. The piece was composed in Rio de Janeiro in the year 1917. It first premiered in Rio de Janeiro in 1918, and was published by Universal in 1922. The influence of Brazilian culture, jazz, and polytonality is very clearly seen in this series of symphonies. According to Milhaud himself, he was quite attracted to the unusual quality of small groups of instruments, which is why he embarked on his series of Petites Symphonies. Due to the fact that he was living in Brazil, acting as assistant to the diplomat/poet Paul Claudel, at the time he wrote this first symphony some of the Brazilian influence can be viewed in his work. This first symphony was written for piccolo, flute, clarinet, oboe, harp, 2 violins, viola, and cello. Overall, this piece has a very simple melody, contains polytonal elements, and possesses a pastoral, folkish feeling throughout. The melodies and pitches evoke a light, airy feeling, such as that of the spring, thus alluding to the symphony's subtitle.

Document 11: Antonín Dvořák: Antonín Leopold Dvořák ( ; ] ; 8 September 1841 – 1 May 1904) was a Czech composer. After Bedřich Smetana, he was the second Czech composer to achieve worldwide recognition. Following Smetana's nationalist example, Dvořák frequently employed aspects, specifically rhythms, of the folk music of Moravia and his native Bohemia. Dvořák's own style has been described as "the fullest recreation of a national idiom with that of the symphonic tradition, absorbing folk influences and finding effective ways of using them."
Document 12: Sinfonietta (Janáček): 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.
