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.
Sigmund Hemmel Sigmund Hemmel (1520–1565) was a German composer, tenor, and Kapellmeister in Stuttgart, Württemberg. He was said to have used a "large polished slate stone for composing." He was director of the Hofkapelle Stuttgart from 1552 to 1554. He is perhaps best known for his "Das Ganz Psalter Davids", a "collection of four-voiced settings of chorales with melody in the tenor voice according to the old custom" published posthumously by Osiander in Tubingen in 1569.
