Robert Schumann's piano music, which Gerhard Oppitz now presents for the third time in a specific configuration of works, displays a special characteristic in contrast to the piano writing of the major 19th-century Romantic piano composers Alkan, Chopin and Liszt. The attempt to categorize his works either as contributions to the Classical models of sonata and variation, or to the Romantic genres of Etude, Ballade, Scherzo and a wealth of dance and character pieces, proved unsatisfactory; that remains the case even though Schumann himself was a regular contributor to the two forms handed down from the Classical era. Schumann himself, then, was engaged in the creative questioning of hitherto valid compositional and musical ideals.
