When did Bach die?

1723- 1750, Bach was the music director of St. Thomas Church in Leipzig, which was a very important position at that time and was responsible for the music affairs of four churches in the city. During his 27 years in Leipzig, he had to deal with the arduous church work that we can't imagine today, but he also served as the director of a student music group in the university and held concerts in cafes every Friday night. I also often held organ performances and was often hired to judge and guide the manufacture of organ. To his embarrassment, he is still tired of begging for humble schools and putting up with bureaucracy and bad habits of municipal committees and officials. It is in this situation that Bach created a surprising number of works during his stay in Leipzig, including many representative works.

1749 visual acuity decreased, two operations failed, and stroke led to blindness. He died in 1750.
