The fact that the  marks are placed earlier in these bars may be related to a slightly different structure of the figuration and the closing nature of music, and hence could have been intended by Chopin. Due to this reason, differently than in b. 13-14, we keep them in the main text, although, according to us, one cannot completely rule out imprecise notation also in this place.

b. 33

composition: Op. 28 No. 1, Prelude in C major

..

One can see a correction in A at the beginning of the bar – Chopin most probably deleted the crotchet e-g-c1-e1 chord and the fermata placed above it. According to us, it means that the final sustained passage was to be written as a common arpeggio (). Had Chopin wanted to both play this chord and perform the arpeggio, written in semiquavers, he would not have provided it with a fermata, which makes sense only in the last bar.
