b. 34-36

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

Slur in bar 34 without continuation in A (→FEGE1), literal reading

No slurs in bars 35-36 in EE3 & GE2 (→GE3GE4)

No slur in bar 35 in EE4

Suggested contextual interpretation of A

Suggested contextual interpretation of FE (→GE1)

..

The end of the slur of A (→FEGE1) in bar 34 (the last in the text's line) suggests continuation in the next bar, yet in bar 35 the slur was omitted in A (→FEGE,EE). In subsequent GE,s the slur in bar 34 was shortened. According to us, lack of slurs in bars 35-36 is a result of Chopin's inattention at the time of writing A (he also omitted accents there), hence we suggest to complete the slurs. Due to the ambiguity concerning the range and possible divisions of the slurs, we give two suggestions.
In EE4 a slur was added in bar 36, which was certainly performed by the reviser.

b. 34-35

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

No marks in A (→FEGE,EE3)

  & accent in EE4

..

The hairpins and accent added in EE4 are certainly an addition of the reviser, probably modeled on authentic indications in bars 2-3.

b. 35-36

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

No marks in A (→FEGE,EE)

Accents suggested by the editors

..

Lack of accents is most probably Chopin's oversight, who omitted here also slurs. Cf. bars 7-8.

b. 37-40

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

..

The sources differ in the presence of accidentals, which, however, does not raise any doubts concerning the text's interpretation. Considering the fact that Chopin and a part of his editors used slightly different rules of validity of the signs written with the use of the octave sign, we state that A is missing two necessary signs, a  before the bottom note of the octave at the beginning of bar 37 (B) and a  before the 14th semiquaver in bar 38 (e1). In FE (→EE) only the 1st of them was completed, in GE – both. According to the rules which are generally applied today, we also consider both flats in the 3rd group of semiquavers in bar 38 (e2 and a1) and a  in the 3rd group in bar 40 (c2) to be necessary. Some of them were added in GE1 (the  of a1) and in EE4 (), while GE2 and subsequent GE,s include all of them.

b. 37-40

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

No fingering in A

Fingering in FE (→GE)

..

The fingering given in the main text – in bars 37-38 – was added by Chopin in a proofreading of FE (→GE,EE). In the latter, Fontana completed it in these and two next bars.
