Well, that famous C major Prelude and Fugue from WTC1. Does anybody think it is easy to play? Me not, since everyone knows every note and recognizes weaknesses, it is really difficult.
C major prelude WTC1:
You have done fairly well, and I like very much that you play it soft. Also from rhythm evenly, that is almost a "trademark" from you.
However your often praised firm touch is on some places not there in the soft playing. Some notes are missing like bar 6 LH 2nd C, same bar RH last note. On some other bars (19,22,28,32) also some not or almost not audible notes.
Regarding interpretation, this is of course matter of taste. I like your tempo, but I think that this prelude sounds better without sustain pedal. If the LH notes are hitten stronger and firm (since they must long for the complete bar) they give the bottom even without sustain pedal. I wonder why you just play the LH notes that soft, although they should sustain long. In general your playing sounds on this prelude (and only here, it is absolut untypical for your playing style) in conjunction with the pedal a bit blurred this way. Also, I prefer a stronger dynamic climax with the loudest point at bar 29. Let me repeat: matter of taste.
C major fugue WTC1:
Great playing in my opinion, also the voice shaping. Some notes especially in the RH lower voice are missing here and there, no big thing (I think missing is in RH: bar 15 3rd 8th note, bar 16 a G in 3rd last 8th). The trills in bar 18/19 don't sound that persuasive to me, also the rhythm in last bar.
Sorry for the nitpicking, because that tends to make the achievement smaller. But it is not small. Your fugue sounds very convincing to me!
F major prelude & fugue WTC2:
Can't say something whether there are notes missing or wrong, because it's too fast to follow for little poor me, so I trust you that everything is ok
I like it, but if you insist on an opinion what could be maybe improved, it is that the LH is always a bit in background in the prelude instead having equal right to the RH.
Great too the fugue. You are a master in the polyphonic playing!
