Three pieces in the soundtrack of the film "Mozart's Sister"

[W.A. Mozart]

I don't know if the pieces that you find here below were composed for the original soundtrack, but if they were not I'd like to know the titles of the pieces.

First piece: a fragment of a violin concerto.

Second piece: sonata for violin and harpsichord played by Mozart and Nannerl.

Third piece: the score of the scene at the minute 01:10:35.

Thanks!

I am not sure but I suspect that they are well made pastiches by the composer of the movie music.
