Mozart was taught keyboard by his father by age four, more specifically the clavichord. By age five he was composing short pieces for the clavichord and teaching himself the violin.
the first instrument that Mozart learned how to play was a clavier, which is very much like a harpsichord

Answer 2

piano, watch the movie Amadeus Mostly, piano, but there is also a scene of him playing violin, on a chair nonetheless, at a very young age. My thought is that directors can play every instrument, a little, enough to make known what the part should sound like.

Answer 3

The harpsichord and violin. But he could play anything really.

Answer 4

it was a clavier.
