b. 49

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

..

While proofreading FE (→GE,EE), Chopin added cautionary accidentals before g1 and g2. In the main text we give only the 1st of them.

It is hard to determine whether the difference between the indications used in A and FE is a result of the engraver's inaccuracy or Chopin's proofreading. Due to the fact that while proofreading FE, Chopin certainly performed corrections in this bar (additions of accidentals, pedalling and slurs), we consider the version of FE (→GE,EE) to be totally accepted. It suggests a slightly longer continuation of increased dynamics in the area of two-three bars after the end of cresc. in bar 48.

Tie in A

No tie in FE (→GE,EE)

..

Oversight of the tie by the engraver of FE (→GE,EE) seems to be more plausible here than Chopin's possible proofreading in FE. Similarly in bars 52-53.

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

in A

in FE (→GE,EE)

..

Change of the indication is probably a result of Chopin's proofreading, who either ordered to change the indication or added a different one in place of the one overlooked by the engraver (it can be indicated by the missing e dim.). The possibility of a wrong interpretation of A by the engraver seems to be much less likely.

in A

No indication in FE (→GE,EE)

Our variant suggestion

..

It is uncertain whether the omission of e dim. in FE (→GE,EE) was intended by Chopin. Due to the fact that it suits the previous indications of both A and FE, in the main text we give it in brackets, leaving its consideration to the performer's judgment.
