Bach was very influenced by a local organist named George Böhm. In 1703, he worked as a musician in the court of Duke Johann Ernst in Weimar.
In 1707 Bach took up a position as an organist at the church of St. Blaise in Mühlhausen. Bach introduced arrangements intertwining different melodic lines even though this went against what the music the pastor believed he needed in the church. One of Bach’s most famous works from this time is the cantata “Actus Tragicus”.
In tribute to the Duke of Brandenburg, Bach created a series of orchestra concerts, which were known as the “Brandenburg concerts” in 1721. These concertos are considered some of Bach’s greatest works.
Bach later became the new organist and teacher at Santo Tomas Church where he was required to teach at Thomas School as part of his position and needed new music for weekly services, hence he launched into writing cantatas.
Bach enhanced the German style established through his skills with the counterpoint, the harmonic organization, and his adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach’s compositions include hundreds of cantatas, both sacred and secular.
Johan Sebastian Bach wrote extensively for organ and other keyboard instruments. He was the author of concerts for violin, chamber music, and for orchestra. His works use the genres of canon and escape. And therefore, he has been considered one of the most important composers of all time.
