Fantasy and Sonata in C Minor are essentially two separate works but are invariably performed as part of a set having originally been paired together by the composer in what was an unusual coupling of works. The formal freedom of the fantasia allowed Mozart to create a particularly expressive example of keyboard music that is in stark contrast to the limitations of the more traditional forms. The Fantasia in C Minor K.475 unfolds in four parts each change of tempo signalling the introduction and development of new material. It is a wonderful and pleasing work with an unmistakable improvisational undertone that draws on Mozart’s most inventive andcreative talents displaying his supreme and consummate ability as composer and pianist. Sonata in C Minor K.457 as is typical of his compositions in C minor is a personal work but not sombre or morose as there is intensity and a sense of drama. A moving and expressive work that is accentuated by the preceding Fantasia.
