What BWV number of Bach single-handedly puts forth the argument for the Equal-Temperment tuning system? The answer is not the Well-Tempered Clavier. (If you have a work in mind it should be easy to find the BWV [Bach-Werke-Verzeichnis] number.)

Just for clarity, the WTC bks 1 and 2 include 48 seperate BWV numbers, so one can't say the WTC.

Now, now you two. I know it feels like there is only half-a-dozen of us right now, but I'm imagining a very large audience. Chris, I expected you to jump all over this one. :wink:

Hehe... I have more fun taking the p*ss than doing puzzles and quizzes :P
And to be honest I don't have a clue.

Though I guess you may refer to the Kleines Harmonisches Labyrinth...

My guess is that J.S. Bach’s methods are explained in C.P.E. Bach’s
“Essay on the True Art Of Playing Keyboard Instruments” ?

My other guess is that J.S. Bach explained details about keyboard instruments
to his son in the “Klavierbuechlein fuer Friedemann” ?

Ok, here's the answer. If the WTC in it's entirety is an argument for accepting the Equal Termperament tuning system (where the octave is divided into 12 equal half steps and keys lose their individual characteristics), by showing works composed in every key - which would be impossible to perform on an instrument tuned otherwise without many awfully sounding keys - then the one Prelude and Fugue which weds together two very distant keys as one, as a sort of "intertonal" wedding of keys from far "opposite sides of the track," would prove the whole argument at once. Such is the case for BWV 843, the Prelude and Fugue in Eb minor/D# Minor from WTC 1. Note that some publications transposed the fugue to Eb minor to correspond to the Prelude with the thought that 6 flats is an easier key to play in (?) than 6 sharps. But the Urtext editions make clear that the fugue is in D# Minor. Thus Bach brings together these enharmonic keys that are 12 stops (not steps) away from eachother on the Circle of Fifths!
