Issues : Omitted correction of an analogous place

b. 1-2

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

Slur from to c1 in A

Slur from B1 to c1 in FC (→GE)

Slur from to B in FE (→EE)

..

In the main text we give the slur of FE (→EE), since the vast majority of subsequent slurs, present in a similar context, is led to the 1st quaver in the next bar in A – out of 13 slurs in b. 1-12 and 15, it is only the slurs in b. 1, 8 and 10 that end on the 6th quaver; two (in b. 6 and 9) are ambiguous. We consider all the above slurs to be inaccurate, since the differences in the range of slurs are not related to the structure of motifs, e.g. the shorter slurs in b. 1 and 8 are opposed by the longer ones in similar figures in b. 2 and 7. Moreover, in A one can see corrections – the slurs in b. 4-5 and 5-6 were being extended (in b. 3-4 probably too). Along with the crossed-out staccato dot at the beginning of b. 2, it may indicate that the concept of markings of those figures changed from  to . Consequently, the aforementioned shorter slurs would be uncorrected elements of the initial slurring.
The slur beginning from the 1st quaver is an inaccuracy of Fontana, repeated in the next three bars too.

b. 3

composition: Op. 63 No. 1, Mazurka in B major

Crotchet E-B in FE (→GE,EE)

Quaver & rest suggested by the editors

..

The crotchet in the sources is almost certainly a mistake, which is supported by the quaver in the R.H. part and by the quavers in an analogous situation in bars 1, 5 and 7. It can be a mistake by the engraver or Chopin's inadvertence, who would often omit one of the few corrected places – see the note in bar 1. Due to the above, in the main text we give a quaver with a rest.

b. 4

composition: Op. 10 No 5, Etude in G♭ major

d3 in A (→FEGE,EE)

e3 in FED

..

A (→FEGE,EE) has das the 3rd note of the 3rd triplet, changed by Chopin to e3 in FED. Taking into account the analogous corrections made in A in bars 12 and 52, we consider this change as definitive.

b. 7-15

composition: Op. 10 No 11, Etude in E♭ major

e1 in A

f1 & e1 in FE (→GE,EE)

f1 & f1 proposed by the editors

..

The change of the inner note in the 4th chord in bar 7 from e1 written in A to ffeatured in FE (→GE,EE) is most probably a result of Chopin's correction. The composer could have striven for a smoother combination of this chord with the next one, without a progression of parallel fifths. According to us, the correction intentionally concerns also two repetitions of this place, in bars 15 and 39 (Chopin omitted one of a few similar places at the time of proofreading on a number of occasions, e.g., in the Etude in G major, No. 5, bar 4).

b. 7

composition: Op. 26 No 1, Polonaise in C♯ minor

Quaver in A

Crotchet in FE (→GE1,EE), 1st instance only

Crotchet in GE2 (→GE3GE4GE5)

..

Chopin added a crotchet stem in the L.H. to the g quaver in the proofreading of FE1. The absence of this correction in the analogous bar in the written repetition in the editions most probably results from Chopin's oversight. We directly include this minor improvement in the main text, which corresponds to both analogous bars in the first editions. An addition was respectively performed in the bar being a repetition of bar 7 also in GE2 (→GE3GE4GE5).
