Fantasy No. 1 with fugue in C major, K. 394 (Fantasie in German) is a piece of music for solo piano composed by Wolfgang Amadeus Mozart in 1782. The fantasy begins with an adagio tempo indication. The opening bars feature strong dynamic contrasts. ( Forte in bar 1 suddenly changes to Piano in bar 2). The opening adagio changes to andante 8 bars later; at this point the right hand starts playing triplet semiquavers, whilst the left hand moves above the right hand for rising quaver arpeggios and then back down to play a descending dotted semiquaver in its normal position alternately. The tempo marking changes again, this time to piu adagio before a final tempo primo 8 bars later. The fantasy ends in G major, the dominant of C major.

The Fugue is marked andante maestoso, which changes to adagio for the final 2 bars. The fugue ends in the tonic key, C major.
