His Relationship In 1723, Bach assumed the position of Thomaskantor in Leipzig, but this was marked by conflicts with the authorities from the outset. His relationship with the city was strained, as he complained about the lack of trained singers and instrumentalists.
In a letter, he responded to accusations from the Leipzig council that he was not fulfilling his duties. Bach's complaints were largely ignored in Leipzig. He even sought alternatives and inquired about possible positions with a school friend in Danzig, while criticizing the Leipzig authorities' lack of musical knowledge. As cantor and teacher, Bach had difficulties with the city council, particularly regarding his conduct as Kapellmeister. Despite these disputes, Bach remained in Leipzig until his death. His focus shifted to the Collegium Musicum and his connections to the Dresden court. In 1733, he traveled to Dresden to strengthen his position in Leipzig. There, he presented the Elector with a new Mass to underscore his musical stature, which earned him the title of Court Composer to the Elector of Saxony and King of Poland. The monumental Mass in B Minor that Bach composed was not performed in its entirety until after his death in 1859. This Mass is distinguished by the unity of various musical styles that Bach combined. It blends gallantry, dance, and profound sacred music, and includes parodies, making it a musical masterpiece. It is a matter of speculation whether it was ever performed in its entirety. With the Mass in B Minor, Bach created a significant work of great variety and depth, comparable to the St. Matthew Passion in its spiritual significance.
The Mass in B Minor is a work of great richness and depth.
