b. 47

d1 in A (→FEEE)

c1 in GE

..

c1 in the chord in GE is an error repeated after the proof copy of FE

No pedalling in A

Pedal in FE

Pedal in GE

..

The pedalling added by Chopin in a proofreading of FE is inaccurate – the  mark is between the first two quavers, so we do not know which one it concerns (there is no  mark at all). In GE and EE the  mark was moved (in a different way), so that the moment of depressing the pedal did not raise major doubts – both solutions may be considered as justified suggestions of guessing Chopin's intention. In the main text we prefer the interpretation adopted in EE, as in Chopin's manuscripts the arrangement of the  mark before the note is much more frequent than after it (most frequently it is certainly under the note).

b. 47-48

composition: Op. 10 No 5, Etude in G♭ major

No slur in A

Slur in FE (→GE,EE)

..

The slur in the editions is certainly an addition made by Chopin during a proofreading of FE.

Our suggestion

..

In FE (→GE1,EE2) lack of the pedal release mark of the pedal depressed in bar 47 should be considered as an inaccuracy. In GE2 and subsequent GE,s, as well as in EE3 (→EE4) a  mark was added at the end of bar 48, which seems to be a reasonable suggestion if we take into consideration authentic indications in bars 45-46.
