This "typical fugue" or school fugue as a concept/model came after Bach's WTC, not before, yes? The "school fugue" did not exist until people studied what these actual "fugues" were about, which people before them wrote out. So this concept was not based on anything exact, but only serves as a fundamental basis for understanding/inspiration to spring from I guess? Or is my history wrong? "Music theory" as we know it today did not exist in Bach's time, correct?
Here is a silly question... Did Bach write "fugues" or did he simply write music ?
(I am obssessed with fugues )
Yes. This is basically correct. Theory is always posterior – it has to be. Mozart had no knowledge of the theory that explains/codifies his works. Beethoven had no knowledge of the theory that formalises his works.
Theory is basically the history of the breaking of rules of theory.
Theory as we know it only started in the early 1700s when Rameau got an epiphany and published his “Treatise on Harmony”. One of the novelties in this work was the revolutionary idea that a major triad is still a major triad even when inverted. Up to then CEG, EGC and GCE were treated as different chords. Before Rameau, music theory was a set of arbitrary rules jealously guarded by guilds of musicians. The great secrecy encouraged the formation of very distinct styles and “schools”, each following different sets of rules. Rameau finished with all that.
As for fugues, there are many other fugues besides Bach’s. And they are quite different as well. It could even be argued that Bach is a special case, and that his fugues are not that typical at all.
How did he compose them? Did he had a plan, a formula? Of course we cannot know. However, there is some evidence that:
1. Bach would compose by inspiration – not by following models or formulas this does not preclude the possibilitiy that formulas were deeply embedded in his unconscious).
2. However, he would often modify his pieces according to formulas and models.
3. Bach was very much into numerology and ciphers, and frequently would modify/plan a piece in order to have ciphers of his name included in it – or references to Christian theology. Like Beethoven, he was forever polishing and perfecting his pieces, and coming up with ameliorated versions of them.
4. And let us not forget that he lived in an era where secret societies were rife (the free-masons, the rosicrucians, and so on) and influencing deeply political and cultural events. I would not be surprised if Bach was involved in such activities (I have read somewhere – but I wasn’t convinced – that just like Madonna, Bach was heavily into Kaballah

– which certainly would be surprising considering his Lutheran upbringing). A very interesting reference if you would like to pursue this train of thought is Frances Yates “The Rosicrucian Enlightenment” (Routledge).
5. And here is a most wonderful book:
James Gaines “An Evening on the Palace of Reason” (Fourth State). You can read a review here:
