| | A Musician's Cosmology: Das Wöhltemperierte Klavier, Vol. 1 (The Well Tempered Clavier) |
 | | The WTC is complete and unique, and the collection of preludes and fugues which was published as “Volume two” is not related to it and would not have been called that by Bach. |
 | | The WTC is one work with forty-eight movements, each unique in form, harmony, meter, which aims to fulfill the “doctrine of affections” by defining twenty-four distinct emotional states, and that’s just with the preludes. |
 | | The old system of seven “real” tones and at least fourteen “altered” tones, all with different pitches, is here consolidated into twelve tones, all equally “real”, opening up a new world of expressive possibilities through chromatic harmony and the “circle of fifths”, which is presented here as fact before it was ever described as theory. |
