b. 5-6

composition: Op. 28 No. 7, Prelude in A major

with bass in A (→FE,FCGE) & EE2

 under semiquaver in CXI

No markings in EE1 & CGS

..

The placement of the  mark in CXI is probably an inaccuracy. However, if the manuscript was indeed based on a lost authentic source, such a later pedal, resulting in the notes ringing out clearer further on in the bar, could have come from Chopin.
The oversight of the  mark is probably an inaccuracy of the copyist – there is a similar situation in bar 8.
The missing pedalling indications in CGS – see b. 3-4.
The oversight of the engraver of EE1 was rectified in EE2.

composition: Op. 28 No. 7, Prelude in A major

Minims a1 tied in A (→FE,FCGE) & EE2

Repeated minim in EE1 & CGS

..

The missing tie of the a1 minim is a mistake both in EE1 and CGS. The error of EE1 was corrected in EE2 on the basis of the Stichvorlage (FE2) or GE1.
