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.

Flute, viola and harp
Flute, viola and harp are the instruments of a chamber music grouping that have become common through the establishment of ensembles that feature this set of instruments and have enjoyed new compositions written for the set.
 The first major composition written for the instruments was the Sonata for flute, viola and harp (1915) by Claude Debussy; Debussy had set out to compose a set of chamber works for "diverse ensembles," as distinguished from more common groupings like string quartet or piano trio.
 Though other composers have written chamber works that feature harp, this set of instruments has gained a repertoire, which places it among other established genres of the twentieth century such as the "Pierrot ensemble" (flute, clarinet, piano, violin and cello, with frequently added percussion or voice). The Seduction of Claude Debussy
The Seduction of Claude Debussy is a 1999 concept album by Art of Noise, featuring a line-up of Trevor Horn, Anne Dudley, Paul Morley, and Lol Creme.
 Also appearing on the album are John Hurt, soprano Sally Bradshaw, Rakim, and Donna Lewis.
 The group blended the music of French impressionist composer Claude Debussy with drum and bass, opera, hip hop, jazz, and narration, and described the album as "the soundtrack to a film that wasn't made about the life of Claude Debussy." Claude Debussy

 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. Federico Moreno Torroba
Federico Moreno Torroba (3 March 189112 September 1982) was a Spanish composer, conductor, and theatrical impresario.
 He is especially remembered for his important contributions to the classical guitar repertoire, becoming one of the leading twentieth-century composers for the instrument.
 He was also one of the foremost composers of zarzuelas, a form of Spanish light opera.
 His 1932 zarzuela, "Luisa Fernanda", has proved to be enduringly popular.
 In addition, he composed ballets, symphonic works, and piano pieces, as well as one-act operas and one full-length opera, "El poeta", which premiere in 1980, starring well-known tenor Plácido Domingo.
 Moreno Torroba also ran his own zarzuela company, which toured extensively, especially in Latin America. Fantaisie for piano and orchestra (Debussy)
"Fantaisie" for piano and orchestra, L. 73, is a composition for piano and orchestra by French composer Claude Debussy.
 It was composed between October 1889 and April 1890 but it received its first public performance only in 1919, a year after Debussy's death, in London by the Royal Philharmonic Orchestra with Alfred Cortot as soloist.
 It is Debussy's only composition for piano and orchestra and, even though it is written in a three movement form, it was not composed as a Piano Concerto.
 Today it is one of Debussy's least frequently performed works.
