Heinrich Schenker is regarded as one of the leading music theorists of the twentieth century. The Masterwork in Music was written in three volumes between 1925 and 1930 and is distinguished from earlier writings by its depth of vision, demonstrated here both graphically and verbally. Although the concept of structural hierarchy is already present in Der Tonwille (1921-4), the idea of a network of layers becomes particularly prominent in Das Meisterwerk. This volume contains a major essay on Mozart's Symphony No. 40 in G minor and other studies of Bach keyboard and solo cello works, Haydn and Reger, as well as theoretical writings on sonata form and fugue and Schenkerian theory. These essays are translated by a team of specialists with ample editoral annotations including comparisons with earlier and later writings.
