Here is the famous C minor prelude from WTK I which I used to play a lot and a piece I kept in my repertoire for a long time. Really good technical exercise too. And it is pretty well executed but I kind of expected a more significant tempo change for the presto
part. But even though it is marked presto
, most Bach experts agree that presto
by Bach's time did not mean b=176 which almost makes it impossible to execute. I would consider reading Sigling Bruhn's in depth analyze of the entire WTC I & II (enormous work she put in there!) and about this specific prelude and fugue at:
You mark the melody very clearly of the first beat of each bar and even make use of the sustain pedal in this set which I am not sure if I ever heard you do before. If I was to choose, I would do a slower and more tempo steady performance but noone can tell you what is right and wrong in Bach (especially on the piano) and that is one thing that makes playing Bach so fun. The fugue is too well executed and you use the sustain pedal there too which I cannot decide is for better or worse.
The P+F in C minor from WTK II is a no pedal recording and a really good performance. Better than the WTK I if you ask me. Very good articulation and phrasing. Candy to my ears and I have really nothing to complain about at all and I feel the same about the E-flat major P+F.
Overall, very good!
