Maurice Ravel's Piano Trio for piano, violin and cello is a chamber work composed in 1914.
 Dedicated to Ravel's counterpoint teacher André Gedalge, the trio was first performed in Paris in January 1915, by Alfredo Casella (piano), Gabriel Willaume (violin), and Louis Feuillard (cello).
 A typical performance of the work lasts about 30 minutes.
The "Konzertmusik" for Brass and String Orchestra, Op. 50, is a work by Paul Hindemith, composed in 1930.

 Koussevitzky conducted the premiere of Hindemith's work with the Boston Symphony Orchestra on 3 April 1931.

Louise Ochsé was a Franco-Belgian sculptor born in the suburbs of Brussels, Belgium, at the end of the 19th century.
 Initially she studied under Constantin Meunier.
 She moved to Paris and exhibited her works at the Salon de la Société Nationale des Beaux-Arts between 1905 and 1914 and at the Salon de la Libre Esthétique from 1906 to 1912.
 On the occasion of her exhibit at the Galerie Boutet de Monvel in 1912, the poet and writer Guillaume Apollinaire praised her work.
 Examples of her art include a bust of Maurice Ravel which now is exhibited at the composer Maurice Ravel museum in the town of Montfort-L'Amaury, outside of Paris, and a bronze mask of composer Claude Debussy which was exhibited at the Musée d'Orsay October 2008 to February 2009.
 A bronze plaque entitled "Challenge de Gramont" is on display at the Fogg Museum.
The international Paul Hindemith Prize promotes outstanding contemporary composers within the framework of the Schleswig-Holstein Music Festival (SHMF).
 The award commemorates the musical pedagogy of Paul Hindemith, who wrote the composition "Plöner Musiktag" in 1932 on behalf of the Staatliche Bildungsanstalt Plön.
 The music prize is endowed with 20,000 € and goes together with a composition commission.
 The prize is presented annually by the Hindemith Foundation in Blonay (Switzerland), the Walter and Käthe Busche Foundation, the Rudolf and Erika Koch Foundation, the Gerhard Trede Foundation, the Franz Wirth Memorial Trust and the Cultural Office of the Free and Hanseatic City of Hamburg since 1990.
 Since 2010, the winner is found partly by a composition competition.
 The work of the prize winner is to be premiered within the framework of the Schleswig-Holstein Music Festival.
The Warsaw National Philharmonic Orchestra (Polish: "Orkiestra Filharmonii Narodowej w Warszawie" ) is a Polish orchestra based in Warsaw.
 Founded in 1901, it is one of Poland's oldest musical institutions.
 The orchestra was conceived on initiative of an assembly of Polish aristocrats and financiers, as well as musicians.
 Between 1901 and the outbreak of World War II in 1939, several virtuoso- and conductor-composers regularly performed their works with the orchestra, including Edvard Grieg, Arthur Honegger, Leoncavallo, Prokofiev, Rachmaninoff, Maurice Ravel, Camille Saint-Saëns, Richard Strauss, and Igor Stravinsky.
 Among the other luminaries who played with the Philharmonic were pianists Ignacy Jan Paderewski and Arthur Rubinstein, violinists Jascha Heifetz and Pablo de Sarasate, and cellist Pablo Casals.
 The Philharmonic has played host to the Chopin International Piano Competition since the contest began in 1927, and also appeared at the inaugural Wieniawski International Violin Competition (1935) and Universal Festival of Polish Art (1937).
Maurice Ravel's sonata for violin and piano is a sonata composed from 1923 to 1927.
 Ravel was inspired by the music of America, namely jazz and blues.
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.
Paul Hindemith ( ) (16 November 1895 – 28 December 1963) was a prolific German composer, violist, violinist, teacher and conductor.
 Notable compositions include his song cycle "Das Marienleben" (1923), "Der Schwanendreher" for viola and orchestra (1935), and opera "Mathis der Maler" (1938).
 Hindemith's most popular work, both on record and in the concert hall, is likely the "Symphonic Metamorphosis of Themes by Carl Maria von Weber", written in 1943.
