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. 6-7

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

Long accents in A

Different accents in FE & EE3 (→EE4)

One accent in EE2

Short accents in GE

..

Two long accents visible in A were reproduced in FE (→EE; in EE2 the accent in bar 7 was overlooked) in varied ways. GE includes short accents in both bars. There is no reason to assume that Chopin interfered with any of the versions.

b. 6-14

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

..

At the beginning of bars 6 and 14 we add a cautionary  before g1.

b. 7

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

c1 in A (→FEEE2EE3)

c1 in GE & EE4

..

In the main text we give c1 after A (→FEEE2EE3). A similar harmonic progression is often to be found in Chopin's works, e.g., in the Etude in E major, No. 11, bars 23-25, therefore, there is no reason to suspect that Chopin overlooked a  in this place. However, in GE (and EE4) a  was added before this c1, changing it into c1. Completing the missing accidentals was the basis of revision in GE, yet Chopin's intention was not always correctly identified (cf., e.g., the Etude in C major, No. 1, bar 46A minor, No. 2, bar 7A major, No. 10, bars 23 and 35). A similar change of cinto c1 was performed in the ending of the Nocturne in B minor, Op. 9 No. 1, published a little bit earlier in the same publishing house (the 11th quaver in bar 83); the change, being an obvious mistake, shows the schematic approach of the edition's reviser.

b. 7

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

f in A

in FE (→GE,EE)

..

In A there is no  returning f on the 9th semiquaver of the bar. It is almost certainly an oversight, corrected by Chopin in a proofreading of FE (→GE,EE).
