Our variant suggestion

..

It is hard to determine what influenced the lack of  in FE (→GE,EE). The engraver of FE omitted or distorted a few such hints in the entire Op. 10. Therefore, we suggest a variant suggestion, giving the indication in brackets.

b. 32-36

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

Pedalling in A (→FEGE1,EE)

GE3 (→GE4GE5)

..

The four-bar pedal in bars 33-36 was already written in A (→FEEE). The  mark, which in FE (→GE1) obviously concerns the beginning of bar 33, placed before the A1-A minim in spite of lack of space, was entirely moved to bar 32 in GE2 and further ones, which suggests an erroneous performance. In addition, in GE3 (→GE4GE5) the  mark in bar 36 was omitted.

Slur in A, interpretation

No slur in FE (→GE,EE)

..

In the main text we give the slur of A, probably overlooked in FE (→GE,EE). We interpret the beginning of the slur in accordance with the sense of music.
