Johann Sebastian Bach - The Well-Tempered Clavier Book 2

Bach wrote the second set of 24 preludes and fugues some sixteen years after the first one.
By this time the fugue was more or less out of fashion, and Bach had begun to attract some criticism for his unnaturally intricate style of composition.
It’s not unlikely that he wrote this second set partly with the aim of silencing his critics, once again demonstrating how the fugue could be made to absorb all sorts of styles and expressions.
