If you can play the prelude/fugue in D major from book 1, and the prelude in G, then you have a good technique to tackle a good number of fugues.
Well, that's good news.
Don't rank them by slow/fast... some of the slowest preludes/fugues are on par with the most difficult.
Well, since Bach didn't write any tempo indication, I guess I'm allowed to play the piece the way which pleases me the most. I read somewhere in the forum (can't remember who said it) that if you play the prelude slowly, you should play the fugue slowly too. Or if you play the prelude fast, the fugue should be fast too. Every prelude should have the same tempo and atmosphere than the fugue. That's interesting, what do you think ?
What about the fugue in C minor from bk1. That was the first prelude/fugue I played (followed by D major, then the G major bk1). The fugue is in 3 voices, and the subject is extremely identifiable.
Yes, indeed C minor in Book I, is often said to be one of the easiest fugue in the work. I'm going to work on it in few weeks I think.
I really like the Prelude in F minor from book 2, and the Prelude in G# minor, also from book 2. Both have some similarities in the melody.
G# minor ? Weird tonality ? And Bach adds lots of double sharps in the score. I guess that's a nightmare to play.
The prelude in C# major from book 1 is really awesome, but if you don't like 7 sharps, then it might be a little hard to read.
C# major : I truly love this prelude (the fugue is tremendous too). It was the first one I wanted to play when I first bought the score. When I opened the book and saw all these sharps, I hated Bach and called him names !
This prelude scares me. I'm not familiar with weird tonalities like these. I should learn some pieces with lesser sharps first.
Thank for all your answers.
