The Sonata in D (K.S76), written in 1789 for Princess Friederike of Prussia, was Mozart's last piano sonata. Its opening theme, which like a trumpet-call, ushers in an Allegro movement notable for its brilliance and ingenuity. The Adagio, one of Mozart's loveliest pieces of piano-writing, is followed by an Allegretto in which tenderness and wit are combined.

Chopin was twenty wihen he composed the Nocturne in C sharp minor, though it was not published until some years after his death. He was twenty-one when, in 1831, he sketched his magnificent Ballade in G minor, completing it four years later. (Harold Rutland)
