Issues : Inaccuracies in FE

b. 57

composition: Op. 10 No 3, Etude in E major

Long accent in A

Accent (?) in FE (→GE1)

Short accent on d1 in EE2 (→EE3)

Short accent on g1 in GE2 (→GE3GE4GE5) & EE4

..

One can have doubts concerning the type of the accent used in A to indicate the beginning of the motif. According to us, it is the long accent that is more likely. In FE (→GE1) the sign was reproduced inaccurately, so that in EE2 (→EE3) it was placed over the 2nd semiquaver in the bar.

b. 58-59

No marks in AI & EE2

Four accents in A

Two accents in FE (→GE)

Accent in EE3

Two accents in EE4

..

Out of four accents in A concerning the notes, only two are in FE (→GE). At the same time, the accent in bar 58 was placed under the note in the L.H., which certainly does not follow from the notation of A. It is probably a result of inattention of the engraver of FE, yet the compliance with the parallel change in the layout of beams suggests a possibility of a coordinated action in this respect, hence Chopin's proofreading.
In #EE1 there are no accents at all, which was completed in EE3 in bar 58, while in EE4 also in bar 59.

Wedge in AI

Dots in A

Wedges in FE (→GE1GE1aGE2) and EE3 (→EE4) & (GE4GE5)

No marks in EE2

Dot & wedge in GE3

..

It is unclear whether Chopin wanted to mark the staccato of the quaver after the semiquaver triplet with a dot, as it is in A, or with a wedge, as it is in AI (only in bar 58) and FE (→GE,EE; in EE2 both signs were omitted, while in GE3 in bar 58 there is a dot). In this case, we consider A as the most reliable source.

Two-voice notation in AI

Single-voice notation in A

FE (→GE,EE)

..

The fact of rejecting the two-part notation is an example of Chopin's striving for simplicity and economy of the notation, so characteristic for him. At the beginning of bar 60 in FE (→GE,EE), there is no stem combining f to e1, which is almost certainly a mistake.

Long accent in A

Lack of the accent in FE (→GE,EE) is most probably a result of an oversight.
