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.
One of Bach's most famously challenging pieces, described by violinist Issac Stern as
"one of the crowning achievements of Man in music". The Chaconne in D minor is a series of 31 variations on a simple chordal theme. The piece lasts 15 minutes and encompasses a huge range of expression and technique, including a blistering double-stopped arpeggio variation which rivals the Paganini Caprices in its technical difficulty.
