b. 31

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

Semibreve in A & GE

Minim in FE (→EE3)

..

The version of A and GE is undoubtedly correct. The single-voice notation of FE (→EE3) is probably a result of a misunderstanding of the autograph's notation. The division into two voices without changing the rhythmic values is certainly a result of the revision of EE4 (similarly in bar 63).

b. 32

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

Accents in A

No marks in FE (→GE,EE)

..

The missing accents in FE (→GE,EE) are certainly a result of the engraver's inattention.

b. 33-34

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

Slur in A

FE (→GE,EE)

..

It is hard to determine whether the slurs of FE (→GE,EE), separated contrary to the clear notation of A, are a result of Chopin's proofreading. Therefore, in the main text we give the undoubtedly authentic slur of A.

b. 33-34

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

No pedalling in A

Pedalling in FE (→EE)

GE2 (→GE3GE4)

..

In the main text we give the pedalling which Chopin added while proofreading FE (→EE). In GE1 the  mark was omitted, which was added in subsequent GE,s, most probably on the basis of the authentic pedalling in bars 19-20. Lack of the mark in GE1 may be a simple oversight of the edition's engraver or be an echo of the error of the proof copy of FE, corrected in the last phase of proofreading.

Four dots in A

Three in FE

Three in GE

Two in EE

..

In all editions, a few staccato dots next to quavers were omitted. They are undoubtedly the engravers' inaccuracies.
