Mozart Sonata No8 In A Minor, K310: I Allegro Maestoso

Completely different turning point is marked by the Mozart Sonata K310 in A minor. During a long visits to Mannheim and Paris between September 1777 and January 1779, Mozart composed the Sonata K310 in A minor, only few month after the Violin Sonata in G major ( a short opera in two movements showing the light, playful character of a divertimento). 
The death of Mozart's mother in July 1778 gave the Piano Sonata an intensity of feeling and drama that the Violin Sonata is lacking. Thanks to the poor succes of that tournee in Paris and the unexpected death of his mother, Mozart suddenly grew musically and personally, finding the way of finally detaching from the strong influence of his father.
