[2] By the end of his apprenticeship he was organist in the St. Thomas church in that town for a short time, followed by some months at Arnstadt where several Bach relatives lived.
As he was not allowed a candle, he could only copy it on moonlight nights, and it was six months before he finished his heavy task.
[8][6] Having stayed with his brother for five years Johann Sebastian left Ohrdruf, joining the choir of St. Michael's Convent at Lüneburg.
[9] Around the time Johann Sebastian left Lüneburg a few years later he composed a Capriccio in E major in honor of his eldest brother, BWV 993.
[10] In the years that followed Johann Christoph copied several compositions by his younger brother, such as those in the Andreas Bach Book, kept by one of his sons, and the Möller Manuscript.
