Issues : Inaccuracies in FE

b. 4

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

Two accents in A (→FE, literal reading)

One accent in GE (contextual interpretation of FE)

One accent in EE

..

It is not entirely clear whether FE has two accents in the 2nd half of the bar, as it is in A, or one, as it is in GE or EE. According to us, in the preceding fragment Chopin clearly expressed his intention of leaving only the accents on the 4th and 10th quavers in bars 1-4 and this is the version, clearly reproduced in GE, that we give in the main text. However, the accent in an analogous place of the 2nd eight-bar section (bar 12) may be considered as an argument for two accents in the discussed place in bar 4. The version of EE is probably a result of revision based on the comparison with bar 12.

The missing  mark is a patent error of the engraver of FE (→GE1,EE), corrected in subsequent GE,s.

Accents in A

FE (→EE)

GE3 (→GE4)

..

In a proofreading of FE (→EE) Chopin reduced the number of accents in these bars, removing the accents at the beginning of the 1st and 3rd three-note groups of quavers. The change, together with a relevant correction of bars 1-4, homogenised the accentuation of the entire 1st eight-bar section of the Etude. In GE – probably due to an accumulation of mistakes – there are 4 accents in bar 6 and then only one in bars 5 and 7 (the accent in bar 5 was overlooked in GE3 and GE4). See also bar 8.

Crotchets in A

Quavers in FE (→GE,EE)

Lack of extensions of c1 and b in FE (→GE,EE), written in A in bars 7 and 8, is most probably an oversight of the engraver.

Three accents in A

Two accents in FE (→GE,EE)

One accent suggested by the editors

..

The presence of the accent at the beginning of the bar in FE (→GE,EE) is probably a result of an inaccurately implemented Chopin's proofreading, in which all remaining accents on the 1st and 7th quavers in bars 5-8 were removed. However, it cannot be excluded that Chopin conserved this accent on purpose – to emphasise the local climax, provided in A with  (cf. another note at the beginning of this bar).
