b. 18-20

composition: Op. 10 No 7, Etude in C major

Long accents in A (→FEEE)

Short accents in GE

..

The type of accents in bars 18 and 20 (short or long) is not clear in FE – in GE they were reproduced as short, while in EE as long. We adopt that, same as in A, they are long accents.

b. 19

composition: Op. 10 No 7, Etude in C major

No mark in A (→FE)

Wedge in GE1

Dot in GE2 (→GE3GE4) & EE

..

Lack of the staccato mark in the middle of bar 19 in A (→FE) should rather be considered to be an inaccuracy. On the other hand, it is not certain which of the signs that appear in this fragment – dot or wedge – would have been used by Chopin if he had noticed this deficiency. In the main text we give preference to the wedge, as Chopin added this sign, while proofreading similar bar 17 in FE. The signs were added by the revisers of GE and EE – wedge in GE1, dot in EE and subsequent GE,s.

b. 19

composition: Op. 10 No 7, Etude in C major

No signs in A (→FEGE,EE)

Our suggestion

..

According to us, lack of dynamic indications in this place may have been a result of Chopin's distraction, as similar motifs were equally marked both earlier (bar 17) and later (bars 21 and 23).

b. 20

composition: Op. 10 No 7, Etude in C major

 in A

No sign in FE (→GE,EE)

Our variant suggestion

..

It is hard to determine whether omitting the  mark in the editions is a result of Chopin's proofreading or the engraver's inaccuracy. In the main text we suggest a variant solution.

b. 21

composition: Op. 10 No 7, Etude in C major

No mark in A (→FEEE)

Dot in GE

..

Lack of the staccato dot under the 1st quaver in A (→FEEE) must be considered as an oversight – cf. bar 23. The mark was added in GE.
