Humoresque and Fugue in D minor - (2102)
The polytonal colors of the opening inform most of the piece. At measure seven and beyond, the lower voices are reflected in the upper, a tenth above. The dissonances are therefore closely related for purely harmonic reasons, with some small detail in the voice leading to add interest.
The fugue subject is again related to Bach's Kunst der Fuge, this time with passing notes and in two voices related by that thematic interval of the tenth. At measure 44 as an example, the B-A-C-H theme in transposition is found as a second motive in the fugue's dense texture.
