Per Nørgård

Per Nørgård was a Danish composer and music theorist. Though his style varied considerably throughout his career, his music often included repeatedly evolving melodies, in the vein of Jean Sibelius, and a perspicuous focus on lyricism. He based music on "infinity series" and other mathematical models. He composed large-scale works, eight symphonies including the choral Third, concertos and operas such as Gilgamesh. His chamber music includes ten string quartets and music for guitar. Some later works were inspired by the art of Adolf Wölfli.
