b. 5-13

composition: Op. 10 No 6, Etude in E♭ minor

Fingering in A

No fingering in FE (→GE,EE)

Our suggestion based on A & FES

..

The '1' digits at the end of bars 5 and 13 (and 45) are written in A. It is hard to determine why none of them is present in FE (→GE,EE). In any case, Chopin's entry in FES in bars 45-46 confirms both the fingering and the need for its indication. Therefore, in the main text we give the 1s written in A. (The fingering written in FES in bar 46 is also given by us in bar 6 – cf. General Editorial Principlesp. 17.)

b. 5-13

composition: Op. 10 No 6, Etude in E♭ minor

 twice in A

 once in FE (→GE) & EE3 (→EE4)

Our variant suggestion

..

In bars 5 and 13 it is not certain whether the difference between the indications (accents,  hairpins) of A and FE (→GE,EE) is a result of the engraver's inaccuracy or Chopin's intervention. In the main text we propose coherent indications of A

b. 5-6

composition: Op. 10 No 7, Etude in C major

Long accent in A & EE

Short accent in FE (→GE)

..

In A the accent in bar 5 is significantly longer than the one in bar 6 (similarly in bars 9-10). A minor difference was reproduced only in EE, which is probably a fortuitous coincidence.

b. 5-14

composition: Op. 10 No 7, Etude in C major

No slurs in A (→FEGE)

Seven slurs in EE3

Ten slurs in EE4

..

The whole-bar long slurs of EE are an arbitrary addition of the reviser who simply copied the authentic slurs from bars 1-4. The revision includes bars 5-11 in EE3 and in EE4 also bars 12-14.

b. 5-6

composition: Op. 10 No 9, Etude in F minor

..

In bar 5 and in the 1st half of bar 6, in AI, instead of part of the L.H., there is come sopra, which, in this context, undoubtedly refers to bars 1-2 and means repetition of the notation of the first three groups of semiquavers.
