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.
The Art of Fugue (Die Kunst Der Fuge) BWV 1080 contains fourteen fugues and four canons demonstrating Bach's complete mastery of the most complex musical counterpoint.
