2 in C minor, K. 396/385f (German: Fragment einer Fantasie in c) is a fragment of a violin sonata composed by Wolfgang Amadeus Mozart in Vienna in August or September 1782.
Maximilian Stadler later composed a "completion" of the work for solo piano which is 70 bars long and ends in C major.
A copy of the piece in Stadler's hand contains a dedication to Constanze Mozart.
"The authorship of the stormy development section is unclear; it has not been determined whether Stadler had Mozart's sketch for this section which has since been lost or it was completely his own creation.
