Heinrich Schenker was one of the most influential music theorists of the 20th century. His treatise on the Ninth Symphony, which was his first major work, contains an analysis of the score, prescriptions for performance and a critical survey of earlier studies of the symphony. Widely acclaimed when it first appeared in Germany in 1912, the book has now been translated into English.
Heinrich Schenker (19 June 1868 – 14 January 1935) was an Austrian music theorist, composer, pianist, and editor whose reductive analytical method, now termed "Schenkerian analysis", elucidates the hierarchical structure of tonal music by tracing elaborations from surface details back to a fundamental Ursatz derived from linear progressions and triadic arpeggiations.
