Prelude (Fantasia) and Fugue in C minor, BWV 537

During his life, Bach had two tenures in the small town of Weimar in present-day Germany. The town had a population of about 5000, but had a strong cultural tradition. He was hired in 1709 by Weimar's ruling duke, Wilhelm Ernst, as an organist and member of the court orchestra; he was particularly encouraged to make use of his unique talents with the organ. Indeed, during this time period he composed many of his greatest organ works, including the Toccata and Fugue in D minor, BWV 565 and the Prelude and Fugue in E major, BWV 566. During his period in Weimar his fame as an organist grew, and he was visited by students of the organ to hear him play and to try to learn from his technique. His Fantasia and Fugue in C minor was composed in the latter part of his tenure in Weimar, but we are not sure as to in which year though; many estimates also put the date of composition in 1723, when Bach was Kapellmeister in Köthen after falling foul of the political tensions that occurred in Weimar in 1717.
