b. 17-18

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

Slur in A (→FE)

Slurs in GE & EE

..

In A (→FE) the slurs between these bars are connected. In FE, due to the graphic layout, in which bar 18 falls in a new line, the issue may raise certain doubts, a proof of which are GE and EE, which give separated slurs.

b. 19-23

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

Slur in A

Slurs in FE (→GE)

GE2 (→GE3GE4) & EE (no slur in bar 21)

..

The slurs in A, despite being added in fragments, were undoubtedly meant to create one continuous slur, running from the beginning of bar 16 to the middle of bar 23. However, in FE (→GE,EE), the slurs between bars 19 and 20 are clearly separated. Moreover, nothing indicates that the omitted in FE (→GE1) continuation of the slur in bar 21, certainly by inattention, was to be connected with the slur beginning in bar 22 (in EE and subsequent GE,s the slur in bar 20 ends on the last note). It is hard to attribute this discrepancy only to the engraver's distraction, on the other hand, it is uncertain what a possible Chopin's proofreading of slurs considered, whether the composer actually wanted to resign from one slur and divide it into two-bar phrases. In this situation, in the main text we give the certainly authentic slurring of A, subject to the fact that Chopin's latest decision could have been the divided slurs of the editions.

b. 20-22

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

No marks in A

Staccato dots in FE (→GE,EE)

..

The staccato dots at the beginning of bars 20 and 22 were added – most probably by Chopin – in a proofreading of FE (→GE,EE).

b. 22

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

Accent in A (→FEGE) & EE4

No mark in EE3

..

Omission of the accent in EE3 is certainly a mistake, corrected in EE4.
