Johann Sebastian Bach (1685-1750) was born in a musical family in Eisenach. When he was a child, he learned violin from his father. Both his parents died when he was 10 years old. He relied on his elder brother and continued to learn music from him. At the age of 15, he left his brother's house to work-study, singing in the choir and playing the organ and violin. He learned composition using the methods of the time, mainly by copying the composer's scores or adapting them. He secretly spent six months under the moonlight copying his brother's music collection, including works by Froberger, Pachelbel, Kehl and Buxtehude. He used his holidays to walk dozens of kilometers to Hamburg many times to listen to and learn from the German organ master Reinken. He also walked 80 kilometers to Celle to listen to a French band.
