Sonata in C minor op. 1

Anton Eberl, nine years younger than Mozart, also began life as a prodigy, and became a friend of Mozart and probably also a pupil; his compositions show such an acquaintance with Mozart's style that misattributions were inevitable.

This dramatic sonata was first published by Artaria as Mozart's Op. 31 in 1794, but reissued with revisions, as Eberl's Op. 1 four years later.
