Louis-Hector Berlioz (] (English: ); 11 December 1803 – 8 March 1869) was a French Romantic composer, best known for his compositions "Symphonie fantastique" and "Grande messe des morts" (Requiem).
 Berlioz made significant contributions to the modern orchestra with his "Treatise on Instrumentation".
 He specified huge orchestral forces for some of his works, and conducted several concerts with more than 1,000 musicians.
 He also composed around 50 songs.
 His influence was critical for the further development of Romanticism, especially in composers like Richard Wagner, Nikolai Rimsky-Korsakov, Franz Liszt, Richard Strauss, and Gustav Mahler.
The Carnival of the Animals (Le carnaval des animaux) is a humorous musical suite of fourteen movements by the French Romantic composer Camille Saint-Saëns.
 The work was written for private performance by an "ad hoc" ensemble of two pianos and other instruments, and lasts around 25 minutes.
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".
Poème élégiaque in D minor, Op. 12 for violin and orchestra (or piano) is the first of Eugène Ysaÿe's poems for string instruments and orchestra.
 The piece first took shape around 1892-1896, but achieved its final orchestrated form in 1902-1903.
 Dedicated to Gabriel Fauré, it served as an inspiration for Ernest Chausson's own Poème, Op. 25.
Joseph Georges-Émile Gaston Allaire (18 June 1916 – 15 January 2011) was a Canadian musicologist, organist, pianist, composer, and music educator of American birth.
 His compositional output includes several preludes for organ, an organ work on French carols, some motets and other choral works, a communion service, a prelude and fugue for string orchestra, and a polyphonic mass.
 He also wrote "Suite laurentienne" for orchestra from which the "Poème" and the "Menuet" were premiered by the Quebec Symphony Orchestra in 1949, and composed the music for the 1953 film "The Man on the Beach".
 His "Marche" (1964) and "Petite Suite" (1965) were both written for the Royal Canadian Ordnance Corps Band.
The Ave Maria by Bach/Gounod is a popular and much-recorded setting of the Latin text "Ave Maria", originally published in 1853 as Méditation sur le Premier Prélude de Piano de S. Bach.
 The piece consists of a melody by the French Romantic composer Charles Gounod that he superimposed over an only very slightly changed version of the Prelude No. 1 in C major, BWV 846, from Book I of J.S. Bach's "The Well-Tempered Clavier", written 137 years earlier.

Jean Émile Auguste Bernard (28 November 1843 – 11 September 1902) was a French Romantic composer and organist.
Amédée-Ernest Chausson (] ; 20 January 1855 – 10 June 1899) was a French romantic composer who died just as his career was beginning to flourish.
Gabriel Urbain Fauré (] ; 12 May 1845 – 4 November 1924) was a French Romantic composer, organist, pianist and teacher.
 He was one of the foremost French composers of his generation, and his musical style influenced many 20th-century composers.
 Among his best-known works are his "Pavane", Requiem, nocturnes for piano and the songs "Après un rêve" and "Clair de lune".
 Although his best-known and most accessible compositions are generally his earlier ones, Fauré composed many of his most highly regarded works in his later years, in a more harmonically and melodically complex style.
