Why was Mozart dissatisfied with his position at the Salzburg court?

Wolfgang Amadeus Mozart was deeply dissatisfied with his position at the Salzburg court because he felt the provincial environment was inadequate for a genius of his stature. His frustrations were multifaceted:1

• Limited Professional Scope: Mozart found his duties in Salzburg to be undemanding and incompatible with his true abilities. He was often restricted by Archbishop Colloredo, who discouraged lavish musical compositions and imposed severe time limits on his mass settings.2
• Lack of Respect: During his time in the archbishop’s entourage in Vienna, Mozart was insulted by his low social standing, noting that he was seated at the table below the valets.3
• Professional Restrictions: The archbishop frequently refused him permission to perform at concerts, denying him significant opportunities to earn income and showcase his talent.3
• Stifled Ambition: Mozart felt the need to escape the restrictive atmosphere of the Salzburg court to find new opportunities that matched his creative potential. These tensions eventually culminated in a stormy confrontation with the archbishop, leading to Mozart's formal discharge in 1781.13
