Heinrich Schenker
Austrian music theorist
Heinrich Schenker (19 June 1868 – 14 January 1935) was an Austrian music theorist whose writings have had a profound influence on subsequent musical analysis. His approach, now termed Schenkerian analysis, was most fully explained in a three-volume series, Neue musikalische Theorien und Phantasien (New Musical Theories and Phantasies), which included Harmony (1906), Counterpoint (1910; 1922), and Free Composition (1935).
Schenker's view on race has come under scrutiny and criticism in the 21st century.
