The Fantasie in C major, Op. 15, popularly known as the Wanderer Fantasy, is a four-movement fantasy for solo piano composed by Franz Schubert in 1822. It is widely considered Schubert's most technically demanding composition for the piano. Schubert himself said "the devil may play it," in reference to his own inability to do so properly.
