b. 70

composition: Op. 10 No 10, Etude in A♭ major

No sign in A (→FEGE1GE2)

 in EE & GE3 (→GE4)

Our suggestion

..

It is unclear whether the lack of the  mark is the notation's inaccuracy or a suggestion of continuing to use pedal as before. The additions in EE and GE3 (→GE4) were certainly performed by the revisers, therefore, we give a suggested similar solution in brackets.

b. 73-75

composition: Op. 10 No 10, Etude in A♭ major

No fingering in A (→FEGE)

Fingering in EE

..

It is hard to consider the very detailed fingering added in EE by Fontana as necessary in the ending of the Etude based entirely on one scheme.

In FE (→EE) the indication dim. was placed under the part of the L.H., while in GE it was not included at all.

b. 75-76

composition: Op. 10 No 10, Etude in A♭ major

Slurs in A, contextual interpretation

No slurs in FE (→GE,EE)

..

According to us, both slurs written in A are too short. Their absence in the editions is probably a result of an oversight of the engraver of FE (it cannot be excluded that he omitted them, not being certain of their range).

b. 75

composition: Op. 10 No 10, Etude in A♭ major

 in A

No marking in FE (→GE,EE)

..

The absence of  in the editions, even if it is not a result of Chopin's proofreading in FE, could have been accepted by the composer who seems to be reducing the number of performance indications (mainly dynamic) in many places, leaving more scope for performers in this respect. Cf., e.g., bars 1-16, as well as notes to the Etude in E major, No. 11, bars 1-14 or Etude in C minor, No. 12, bars 2-10.
