Fantasia in F minor, D.940, op. posth.103

The Fantasia in F minor by Franz Schubert, D. 940 (Op. posth. 103), for piano four hands (two players at one piano), is one of his most important works for more than one pianist and one of his most important piano works altogether. He composed it in 1828, the last year of his life. A dedication to his former pupil Caroline Esterházy can be found only in the posthumous first edition, not in Schubert's autograph.

Specifically including the Fantasia in F minor, musicologist Christopher Gibbs has written, "Schubert's music for piano duets is among not only his greatest but also his most original".
