b. 5-6

composition: Op. 10 No 2, Etude in A minor

No fingering in Ap & FE (→GE)

Additional fingering in EE

..

In EE Fontana added here the fingering which was the literal repetition of Chopin's indication for the upper voice in bars 1-2.

b. 5

composition: Op. 10 No 12, Etude in C minor

 in A

No marking in FE (→GE,EE

Our variant suggestion

..

In the main text we suggest a possibility of adding  from A to the dynamic markings of FE (→GE,EE). Lack of any suggestion of emphasising the climax of the chordal motifs in the introduction may be considered here as an inaccuracy of notation.

b. 5

composition: Op. 10 No 12, Etude in C minor

in A, contextual interpretation

No indication in FE (→GE,EE

Our variant suggestion

..

Not being certain whether the lack of sempre legato in FE (→GE,EE) is accidental, we give the indication in brackets. In bars 45-46 the analogous passage is embraced with slurs in all sources, which indirectly confirms the legato articulation also in this case. In spite of the fact that the indication in A begins only in the 2nd group of semiquavers, its binding force from the beginning of the passage is undeniable.

b. 5-6

composition: Op. 10 No 11, Etude in E♭ major

..

In A there are visible traces of a change of the bottom note in the 3rd chord in bars 5-6 (as well as in bars 13-14, which are marked in an abbreviated form in A as a repetition of bars 5-6). Originally, all the places featured c2, hence Chopin proceeded from the strictly analogous version to bars 1-2. Cf. bars 37-38.

b. 5-13

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

No pedalling in A

Pedalling in FE

..

Chopin added the pedalling in bars 5 and 13 in a proofreading of FE. At the same time, the  mark in bar 13 was omitted, which is certainly a mistake (of Chopin or the engraver). The missed sign was added in GE, after bar 5, and in EE, in which, however, the  mark was placed in the middle of the bar. In the main text we add the sign after the most probably authentic pedalling in bar 5.
