The Warsaw Philharmonic Orchestra (Polish: Orkiestra Filharmonii Narodowej w Warszawie) is one of Poland's leading musical institutions.
It was established in 1901 on the initiative of an assembly of Polish aristocrats and financiers, as well as musicians. Between 1901 and the outbreak of World War II in 1939, a group of virtuoso - and conductor - composers regularly performed their works with the orchestra, including Edvard Grieg, Arthur Honegger, Ruggiero Leoncavallo, Sergei Prokofiev, Sergei Rachmaninoff, Maurice Ravel, Camille Saint-Saëns, Richard Strauss, and Igor Stravinsky. Among the other artists who played with the Philharmonic were the pianists Ignacy Jan Paderewski and Arthur Rubinstein, the violinists Jascha Heifetz and Pablo de Sarasate, and the cellist Pablo Casals. The Philharmonic has served as host to the Chopin International Piano Competition since the contest's birth in 1927, and also appeared at the inaugural Wieniawski International Violin Competition (1935) and Universal Festival of Polish Art (1937).
The Warsaw Philharmonic Orchestra also has worked in videogame soundtracks, namely Sega's Phantasy Star Universe and Square Enix's Final Fantasy XIII; alongside the OST of Ace Combat 5: The Unsung War—more specifically, in the making of the title overture, The Unsung War.
