b. 12-13

composition: Op. 28 No. 21, Prelude in B♭ major

No slur in FC (→GE)

..

In A, the slur starting in bar 12, last in line, indicates a continuation, but its ending is absent from bar 13. We adopt a natural contextual interpretation in accord with the FE (→EE) version. In FC (→GE), the copyist overlooked this slur like the previous one.

b. 14-16

Continuous slur in A

In A the phrase mark in b. 15, which opens a new line, is ambiguous – it starts over the 1st chord, but its shape indicates that it should be a continuation. The ending of the phrase mark in b. 14, dragged far beyond the bar line, is an argument for a continuous phrase mark, which we give in the main text. Therefore, we consider the division of the phrase mark in FE (→EE) to be an erroneous interpretation of A. In turn, in FC Fontana reproduced the continuous phrase mark in b. 14-15 correctly, but he marked its continuation between b. 15 and 16 very inaccurately (b. 16 opens a new line in FC), hence the version of A cannot be guessed on this basis.

b. 15-18

composition: Op. 28 No. 8, Prelude in F♯ minor

Coninuous slurs in A (→FE), probable interpretation

..

In A (→FE) b. 15 and 17 fall at the end of the line, and the slurs running over them go quite clearly beyond the bar lines, thus suggesting a continuation. However, the slurs in b. 16 and 18 rather do not confirm that. In FC (→GE) Fontana interpreted them as divided; separate slurs are also to be found in EE. In the main text we interpret them as combined, which is compliant with the structure of this fragment, consisting of a two-bar phrase presented twice in contrasting dynamics.

b. 16-17

composition: Op. 28 No. 4, Prelude in E minor

No slur in As & FC (→GE)

Slur to end of bar 16 in A (contextual interpretation) & CGS

Slur to bar 17 in A (possible interpretation→FE→EE)

..

In A b. 16 ends the line, while the L.H. slur, going clearly beyond the end of the bar, suggests a continuation. However, there is no ending of that slur in b. 17, hence it is unclear whether Chopin forgot to enter it or whether it is the ending of the slur in b. 16, written with a flourish (cf. e.g. the Scherzo in B Minor, Op. 31, b. 60369), that is inaccurate. There is also a possibility that Chopin changed the concept of the slur after having added an octave at the beginning of b. 17 – one can see a crossing-out over the initial version of the 1st quaver in A; it could have concerned the ending of the slur. In the main text we give a slur reaching the end of b. 16; the version of FE (→EE) can be, however, considered an acceptable variant.
The shorter slur of CGS is probably an inaccuracy.

b. 17-18

composition: Op. 10 No 12, Etude in C minor

Slur in A, interpretation

Slurs in FE (→GE,EE

..

In A the slur in bar 17 (the last one on the page) suggests a continuation, which is, however, not confirmed by the slur in bar 18. FE (→GE,EE) includes separated slurs. Taking into account the fact that the slur in bar 18 in A is evidently inaccurately written, we assume that Chopin's intention in this place was most probably one slur until the end of bar 18.
