In March of 1700, shortly before his fifteenth birthday, Johann Sebastian Bach is on its way. His luck eventually leads him to Lübeck, where he met Andreas Werckmeister and the well-tempered tuning. But the perfection has its price: all sounds are a bit "heated", the music has an air of artificiality. And not only the sounds, the nature and the people also were tempered. Gardens are laid out with geometric precision, rivers are channeled, the new cities are well designed, the night street is full of light... The world is on the way to the artificiality. When Bach has completed the Well-Tempered Clavier, afflicts him the abysmal doubt: is this work is not "just out of this world", perfect, artificially, profane?
The novel is a philosophical novel in which it comes to the mood of the world in the truest sense. Or to the detuning of the world by the well-tempered tuning, in which all tones are a little distorted. Thus, the departure has begun in a new world that is increasingly artificial. Bach comes at the end in an existential doubts with which he is finally reconciled only after he composed the St Matthew Passion and has been listed.
Jens Johler tells the story of a highly gifted young musician, who is looking for the harmony of heaven and earth. The recently published book has a very favorable reception, and the author has been invited to talk to secondary school students on Bach's life and work.
