Mozart completed his Fantasia in C minor on 20 May 1785 and it was published in December 1785 (in tandem with the Piano Sonata in C minor K457) with a dedication to Therese von Trattner (1758–96), one of Mozart’s favourite pupils. The Fantasia shows Mozart at his most audacious and the Mozart scholar Alfred Einstein wrote that the work ‘gives us the truest picture of Mozart’s mighty powers of improvisation – his ability to indulge in the greatest freedom and boldness of imagination, the most extreme contrast of ideas, the most uninhibited variety of lyric and virtuoso elements.’ This extraordinary work combines tragic grandeur with a relish for extreme chromaticism and bravura, alongside moments of great tenderness.
