All the Music was made by the Note,
and without the Note was not any music made that was made.
There was a man sent from God, whose name was John.
The same came for a witness, to bear witness of the Light of the Music.
In the daytime, the light was from the sun.
In the night, the shadow was from the stars.
The day was made of twelve hours of daytime and of twelve hours of night.
So was the Music.
The Note was made of twelve tones namely all the tones and semitones.
And sequenced in the major scale or in the minor scale.
The Music was in twenty-four keys, and without them was not any music that was made.
The Well-Tempered Clavier
Fugues through all the tones and semitones
including those with a major third or Ut Re Mi
as well as those with a minor third or Re
Mi Fa. For the profit and use of
musical youth desirous of learning
and especially for the pastime
of those already skilled in
this study composed and prepared by
Johann Sebastian Bach
There are two books called as the Well-Tempered Clavier, Book 1 and Book 2. Which one do you like better? I love both. But some preludes and fuges of each book impress me a lot more than others. According to the history, the Book 2 was not named as such by J. S. Bach. It was named by Johann Christov Altnikol, his son-in-law. We don't know why Bach had completed the second book about 20 years after of the Book 1.
Many people argue about the meaning of "Well-Tempered". Some say it dose not mean "Equal-Tempered". The "Equal-temperament" is thought to be a compromise. But the Nature has sometimes a fuzzy aspect. On the Uncertainty Principle by German physicist Werner Heisenberg ( published in 1927 ), the position and the velocity of a subatomic particle cannot both be measured exactly, at the same time, even in theory. In future, someone would find a new music theory for this temperament issue.
J. S. Bach gave the Well-Tempered Clavier to "musical youth desirous of learning and especially for the pastime of those already skilled in this study". Then why do we have to listen to the performances of great pianists? Great pianists should have played it for thier own pastime. I think that the value of the Well-Tempered Clavier will emerge when we play it by ourselves like singing hymns in our church. Oh, no, we cannot play the piano well. Then there is a way. We can transcript the score on our notebook and enjoy the transcription work itself. Oh, no, we cannot hear the music. Right. But if you transcript the score into midi data, you can listen to the music freely.
