Musical Limitations: Mozart felt a lack of creative opportunities and support for his music in Salzburg. The city's musical scene was conservative, and Mozart yearned for broader horizons where his talents could be fully appreciated.
Frustration with the Social Structure: Salzburg's social structure was very hierarchical, and Mozart felt restricted and constrained by the Archbishop's authoritarian leadership and courtly etiquette. He aspired to escape the limitations imposed by the social hierarchy and pursue his career independently.
Desire for Growth and Learning: Mozart was eager to expand his musical knowledge and skills. He sought new challenges, influences, and collaborations, which he believed could be found outside of Salzburg. He wanted to learn from other musicians and explore different musical styles.
Career Ambitions: Mozart was ambitious and wanted to establish himself as a renowned musician and composer. He understood that the opportunities and recognition he craved were more readily available in major musical centers such as Vienna and other European cities.
Personal Freedom and Independence: Mozart longed for personal freedom and autonomy in his artistic decisions and career. He wanted to be free from the constraints and control imposed by the Archbishop and the Salzburg court.
It was a combination of these factors that ultimately led Mozart to leave Salzburg in 1781, seeking a more fulfilling and promising trajectory for his musical career.
