Although Schoenberg viewed his twelve-tone method as an extension of the Germanic musical evolution from Bach to Brahms, one group of writers in America identified twelve-tone antecedents with Medieval and Renaissance polyphony. Such a correlation of Schoenberg's practice with this textural orientation of the past was part of a larger movement (what I term "neopolyphony") recognizing twentieth-century musical developments as the genesis of a polyphonic epoch reviving both the technical and aesthetic concerns of the former era. With Schoenberg's practice applied to this analogical context, other writers (Hill, Krenek, Perle) advanced certain modal theories based in various degrees on the internal organization and functional role of the Church modes.
