b. 8

composition: Op. 10 No 8, Etude in F major

No slur in A (→FEGE,EE3)

Slur in EE4

Our suggestion

..

In this context, lack of the slur over the semiquavers in the R.H. must be considered as Chopin's inaccuracy, which is justified by the revision introduced in EE4.

b. 9-12

composition: Op. 10 No 8, Etude in F major

No accents in A

Accents in FE (→GE,EE)

..

The accents added in FE (→GE,EE) may be a result of Chopin's proofreading. However, according to us, it is more probable that they were additionally added by the engraver of FE, who either did not observe the change in accentuation or he considered it to be the manuscript's inaccuracy. Cf. the Etude in C major, No. 7, bars 54-55, C minor, No. 12, bars 2-4.

b. 10-12

composition: Op. 10 No 8, Etude in F major

Slurs in A

No slurs in FE (→GE,EE)

..

According to us, the 2nd slur in bar 10 and the slur in bars 11-12 were omitted in FE (→GE,EE) due to the engraver's inattention.
