Changes

Bach compiled the first part in 1722, followed by the second in 1742, intending them for the study of keybard playing. They were not published until the 19th century, but after Bach's death they were well known by some influential Leipzig-based keyboardists such as C. G. Neefe, who taught [[Beethoven]] in Bonn. They were also known by [[Mozart]], and both [[Frederic Chopin]] and [[Sergei Rachmaninoff]] claimed to have played a prelude and fugue every morning.
