A comparison with similar b. 2, 10 and 12 proves that Chopin wanted the c
1 note to be heard in the 2nd half of the bar too. Therefore, it was certainly wrong of Fontana to shorten its value. It would be more justified to extend the length of the note with a dot, as was performed in the aforementioned bars; however, it is not necessary due to pedal. The change in EE2 was most probably introduced under the influence of GE1 (other examples of wrong versions of GE1 having been introduced into EE2 – see, e.g. the Prelude No. 5 in D Major, b. 16, No. 21 in B
Major, b. 4 or No. 24 in D Minor, b. 47-49).
