Merri Jean Baptiste Franquin (b. 19 October 1848, Lançon, Bouches-du-Rhône, France, d. 1934) was a French trumpeter, cornetist, and flugelhornist who was professor of trumpet at the Paris Conservatory from 1894 until 1925.
 Franquin was a teacher of both Georges Mager (1885–1950) who was principal trumpet of the Boston Symphony Orchestra from 1919 until 1950, and Eugene Foveau (1886–1957) who became professor of cornet at the Paris Conservatory in 1925.
 His collaboration with Romanian composer Georges Enescu (1881–1955) led to the composition in 1906 of "Légende", one of the great twentieth-century works for solo trumpet and piano.
 Franquin's book, "Methode Complète de la Trompette Moderne de Cornet a Pistons et de Bugle", has been an influential teaching aid for many trumpet players, notably Maurice André.
 Franquin's most notable accomplishment while at the Paris Conservatory was his push for the C Trumpet to replace the low F trumpet as a more versatile orchestral instrument.
 A more modern form of this instrument was introduced to American symphony orchestras by Georges Mager, and it remains very much in popular use in the United States.
Manuel de Falla y Matheu (] , 23 November 187614 November 1946) was a Spanish composer.
 Along with Isaac Albéniz and Enrique Granados, he was one of Spain's most important musicians of the first half of the 20th century.
 His image was on Spain's 1970 100-pesetas banknote.
Félix Battanchon (9 April 1814 – 1893) was a French cellist, composer, and one of the venerated teachers at the Paris Conservatory.
 He studied at the Paris Conservatory with Olive Charlier Vaslin (1794-1889) and Louis Pierre Martin Norblin (1781-1854).
 In 1840 he entered the orchestra of the Grand Opéra.
 He applied for second teacher of cello in 1851.
 Little is known about his life until his death in Paris in 1893.
This is a list of operas by Argentine composers.
 Argentina's first native born opera composer was Francisco Hargreaves (1849-1900) who composed "La gatta bianca" (1875) and "Los estudiantes de Bologna" (1897), followed by Zenón Rolón (1856-1902) who composed several operas as well as operettas and zarzuelas.
 The works of many of the composers from this generation were first performed outside Argentina.
 Native Argentine opera was to develop much more with the massive European (mainly Italian) immigration in the late 19th century and even more with the opening of the Teatro Colón in 1908 where most of the 20th century operas listed here had their world premieres.
 Some of the first operas to treat Argentine subjects or national themes were Arturo Berutti's "Pampa" (1897) based on the life of Juan Moreira and "Yupanki" (1899) based on the life of Inca warrior Manqu Inka Yupanki.
 Also notable in this genre were Felipe Boero's "Tucumán" (1918) set during the Battle of Tucumán and "El matrero" (1929).
 Considered by many to be the quintessential Argentine opera, "El matrero" had a libretto based on gaucho folk tradition and incorporated Argentine folk melodies and a traditional gaucho dance.
 The Spanish playwright Federico García Lorca was also the inspiration for several Argentine operas.
 His plays, "La zapatera prodigiosa" and "Bodas de sangre", were the basis of operas by Juan José Castro, while Osvaldo Golijov's 2003 opera "Ainadamar" is based on events in the playwright's life.
Bruno Mantovani (born 8 October 1974) is a French composer.
 He has been awarded first prizes from the Paris Conservatory which he joined in 1993.
 His work has been commissioned by the French government as well as other organizations.
 In September 2010 he was appointed to the post of director of the Paris Conservatory.
Aurora is an opera in three acts by the Argentine composer Héctor Panizza (also known as Ettore Panizza) set to an Italian libretto by Luigi Illica and Hector Quesada.
 Composed in 1907, "Aurora" became the second national opera of Argentina, after Felipe Boero's more popular "El Matrero".
 Although its plot is set in Argentina, "Aurora" is Italian in style.
 Panizza's score shows a strong influence of Giordano and Mascagni.
Cornelius Gurlitt (10 February 1820 – 17 June 1901) was a German composer born in Altona, Schleswig-Holstein.
 He was a classmate of Carl Reinecke, whose father was head of the famous Leipzig Conservatory.
 Gurlitt studied with Reinecke's father for six years.
 His first public appearance at the age of seventeen was well received, and he decided to go to Copenhagen to continue his studies.
 There he studied organ, piano, and composition under Curlander and Weyse.
 While in Copenhagen he became acquainted with the Danish composer Niels Gade, and they remained friends until Gade's death.
