Anton Bruckner Josef Anton Bruckner (] ; (1824--)04 1824 (1896--)11 1896 ) was an Austrian composer best known for his symphonies, masses, and motets. The first are considered emblematic of the final stage of Austro-German Romanticism because of their rich harmonic language, strongly polyphonic character, and considerable length. Bruckner's compositions helped to define contemporary musical radicalism, owing to their dissonances, unprepared modulations, and roving harmonies.
Missa cuiusvis toni Missa Cuiusvis Toni (Mass in any mode) is a four-part musical setting of the Ordinary of the Mass by the 15th-century composer Johannes Ockeghem. It is found in late-century manuscripts, including the Chigi codex (c. 1498–1508), and was published in 1539, 42 years after the composer's death in 1497.
