4 Ballady / Nokturny. op. 48 / Scherzo b-moll, op. 31

4 Ballady / Nokturny, op. 48 / Scherzo b-moll, op. 31 is a collection of solo piano works by Fryderyk Chopin, published in the early 1840s (circa 1841–1842). The music juxtaposes expansive, narrative ballades, nocturnes characterised by singing melodic lines over rich harmonic support, and a scherzo that demands considerable technical agility, reflecting Chopin's mature style and its place in nineteenth-century piano repertoire.
