Konstanty Paschalski’s Berceuse Op. 35 No. 3 is a rare example of Polish salon music from the mid-Romantic era. It is distinct for its rich harmonic color and delicate, nuanced melodic writing.
The player must master the subtle balance between the inner harmonic voices and the singing upper melody.
