b. 45

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

..

GE1 has a  before the topmost note of the last chord. This quite obvious error was originally also in FE, in which, however, it was corrected in the last proofreading. EE, GE2 and subsequent GE,s also include the correct version.

b. 45-46

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

No pedalling in A

Pedalling in FE (→GE,EE)

..

The pedalling was added by Chopin in a proofreading of FE (→GE,EE).

Slur in A

Inaccurate slur in FE (→GE1)

Slur in GE2 & EE

No slur in GE3 (→GE4GE5)

Our suggestion

..

In the sources of undeniable authenticity – A and FE – the slur is inaccurately written. In both sources it generally includes bar 46, yet in A it most probably reaches the 1st quaver in bar 47, while in FE (→GE1) it suggests a continuation from bar 45 (written in the previous line). In GE2 and EE the sign of FE was repeated, shortening its left end to avoid the notation's inaccuracy. In the main text we propose a slur embracing the entire phrase.

b. 45-47

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

Dot in A

Three dots in FE (→GE1GE2) & GE5

Two dots in EE & GE3 (→GE4)

..

The staccato dots at the beginning of bars 45 and 47 were added in a proofreading of FE to the dot written in A over the 2nd quaver in bar 47 (it cannot be excluded that the dot of A was overlooked and Chopin added all three marks at the time of proofreading FE). In EE the sign at the beginning of bar 47 was omitted, perhaps as a result of an oversight or revision. In turn, lack of the dot in this place in GE3 (→GE4) must be an error, corrected in GE5.

  in A

FE (→GE1,EE)

 

Our suggestion

..

It is unclear how the discrepancies between A and FE surfaced. Allegedly, there are a few factors to be considered: the inaccurately recreated hairpins of A and an ad hoc proofreading by Chopin in FE (→GE1,EE). In the main text we suggest a set chosen from the signs of FE, following the natural phrasing, which also stems from the notation of A. In GE2, and to a lesser extent in subsequent GE,s, the signs between the staves were assigned to the part of the R.H.
