The Couperin family occupies the same dominant position in French musical life of the Baroque era as does the Bach family in Germany. However, there was never any doubt who was the most commanding figure in the family: even in his lifetime, Francois Couperin was known as Couperin le Grand. His contribution to the literature of keyboard music has prompted comparisons with Bach in its mastery and Chopin in its precision of feeling and poetic insight. This guide examines not only the Ordres or Suites but the whole of his output including the organ masses, motets and chamber music.
