Franz Schubert’s biographers puzzle over why this brilliant composer, who was not fully appreciated during his lifetime, left so many incomplete scores and sketches. As in the case of his most famous unfinished work (the Symphony in B minor), it is unclear why Schubert abandoned the work he had begun in the winter of 1820 on a quartet in C minor (after all, the completed first movement promised a fine work). Happily, this was not Schubert’s last word in the genre, and the sole movement of the incomplete quartet functions today as the Quartettsatz in C minor. 

Thirty-five years earlier, Wolfgang Amadeus Mozart had received a commission from an enterprising Viennese publisher for a cycle of uncomplicated piano quartets, popular with amateur musicians performing at home. However, Mozart’s works stood out from similar repertoire and heralded the arrival of the great Romantic forms sometimes referred to as chamber piano concertos.

One could hardly speak of amateur addressees of Robert Schumann’s Piano Quintet in E flat major, as he dedicated the work to an extremely talented pianist, his wife Clara. She was the soloist in the work’s public premiere at Leipzig’s famous Gewandhaus. The composition, which gives the pianist hardly a moment’s rest, was written at a time when the Schumanns were passionately engaged in analysing the keyboard music of Johann Sebastian Bach.
