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.

 in A & GE2 (→GE3→GE4)

No sign in FE (→GE1,EE)
..

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

..

The hook at the bottom of the natural raising d3 to d3, resulting from haste while writing A, was initially interpreted in FE as a flat before f2. The mistake was then corrected.

b. 5-7

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

Accents in A

FE (→EE)

GE1 (→GE2)

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.

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

..

In the 2nd four-bar section Chopin wrote the accidentals less carefully. In A (→FE) there are no naturals before b2 in bar 5 and d3 in bars 7-8. These patent oversights were corrected in GE and EE (in EE3 the  in bar 7 was not completed).
