The wrong note (in this snatch) occurs on beat 2 of bar 18 where the LH inner part plays Bbb instead of Bb - this happens also on the repeat. The remainder of the piece, too, is littered with misreadings that the performer's ear is unable to identify. The performance was not live, but recorded!
It was not Wanda anybody - but the inimitable Leon Berben (the only player I know who has managed to play the entire cycle of 96 movements with at least 96 crackpot interpretations).
Indeed now that the Member points it out it does sound awful. We wonder where the player - we have of course never heard of this Berben - got that from. He does also make silly and unnecessary pauses, and has we agree little feeling for the spirit of the music. But then again would any one who
had feeling for the spirit of the music ever try to play it on a harpsichord?
Here or
here is another interpretation of the Prelude, also crackpot no doubt but at least it gets the B flat right.
Incidentally the Member has in his last message unknowingly suggested the idea for and even the name of a wonderful new thread which will appear to-morrow!
