Anyone who knows anything about Bach knows that he was GOAT of counterpoint, master of many styles, incredibly prolific, writing with an emotional depth virtually unsurpassed by any other composer.
The WTC is obviously incredibly popular and is canon for any serious pianist. So it raises the question: why aren't there more cycles like it?
I think there are two reasons.
Reason one: Originality
Among composers, I think there is strong disincentive to follow in this particular set of Bach's footsteps. If you were to mention it to people (and I have), questions like "it's been done before" and "Why would anyone listen to yours? They have Bach" come up, and they are hard to rebut. Composers naturally seek originality, and when writing a fugue, it is very difficult to write one that does not sound like Bach, but worse. The more logical route to originality and finding an audience, then, would be to do something OTHER than writing a prelude and fugue cycle.
While nearly every composer since Bach has probably written a fugue in their training, I think very few tried a whole cycle.
Reason two: Melody
Of those that did, most notably Shostakovich and Kapustin, none achieved the WTC's level of popularity despite some degree of critical acclaim. I argue that the reason is melody.
For all of Bach's technical genius, he was also a great melodist. You can pick virtually any piece in the WTC, and the fundamental idea in the piece is likely a rhythmic and memorable melody, like a 1700s pop song. While the cycles by Shostakovich and Kapustin had their merits, imo few would call them "melodic" or "catchy".
So I'm putting this to the test. I'm a classically trained pianist and former pop songwriter. I'd been writing fugues to keep my composer brain warm when it was busy with non-music projects, and then I thought, why not write a whole cycle? I think there are plenty of people out there who would like to hear a new cycle that is grounded in counterpoint but with new, memorable melodic ideas. The first piece, "Amaze x1" aka Prelude in C, is in the video below.
What do you think? What else beyond melody makes the WTC stand up against every attempt that came after? Why else were there so few attempts in the first place?
And most relevant to me, will anyone be interested in a melodic new cycle of preludes and fugues for piano? That's the experiment after all.
