One of the greatest composers of all time. Bach wrote hundreds of pieces for organ, choir, as well as many other instruments. He spent most of his life as a church organist and a choir director. His music combines profound expression with clever musico-mathematical feats, like fugues and cannons in which the same melody is played against itself in various ways.
Composed during Bach's tenure at Weimar, where he was organist, violinist and composer to the Duke of Weimar. It is from this period that much of Bach's organ music was written.
