Third, expanded edition of "Fiction and Facts." Everyone has heard of Johann Sebastian Bach's Well-Tempered Clavier, but hardly anyone knows about his journey to F-sharp major. In March of the year 1700, shortly before his fifteenth birthday, Johann Sebastian Bach sets out on his way. His goal: to create perfect music, music that unites heaven and earth in harmony. His search ultimately leads him to Lübeck, where he meets Andreas Werckmeister and learns about the well-tempered tuning. In this tuning - which is new! - everything can be played, all keys, in major and minor. But perfection comes at a price: all tones are slightly tempered, meaning altered, and from now on, the music has a touch of artificiality. And not only the tones, but also nature and people are tempered. Gardens are laid out with geometric precision.
