Here Rheinberger drew on his two-piano arrangement of the Goldberg Variations not only for the choice of instruments, but also for his arrangement technique. At times Mozart's piano part alternates between the two pianos, though usually new parts are added to flesh out the texture harmonically in various ways. Occasionally Rheinberger also adds motivic parts, though never with the same skill or density as in the Goldberg Variations. In this, however, he demonstrates a consummate sense of style precisely by adhering to the compositional fabric of his original models.
