This is a variant record for the Ballade Polonaise by Giżycka-Zamoyska, representing a standard salon-style work of the era. Its appeal lies in the fusion of Slavic rhythmic sensibilities with lyrical piano writing.
Pay close attention to the articulation of the polonaise rhythm to avoid a heavy, sluggish performance.
