What to learn after Prelude and Fugue in c minor in Bach's WTC?

[doubleconcerto]

I learned both over the summer and felt like I played them at a satisfactory level. What piece in the WTC would be a logical next step from these two? Ideally, I'd like to learn a prelude followed by a fugue (sequential).

The D Major P&F from Book 1's a good one. Most people don't think it's too hard, there's many recurring patterns. I had a bit of trouble on the prelude but it's not too bad, and the fugues's quite simple even though it's 4 voices.

I agree that the D major fugue from Book I is not too hard. And the prelude does not have to go by at light speed - at a moderate tempo it's still interesting and not that hard. The D minor Prelude and Fugue are also good. The prelude sounds harder than it actually is, and sounds fine at a less than presto tempo. The fugue is only slightly harder than the C minor, and it's sort of fun because it uses inversion of the subject, which the C minor does not.

i would learn the one in b flat major book 1, its a very fun piece
