b. 8

composition: Op. 35, Sonata in B♭ minor, Mvt III

..

Same as bars 2, 5 and 12-13, in GC bar 8 is written in an abbreviated manner with / signs (one on each stave). The interpretation of this notation, undoubtedly repeated after [A], turned out to be not entirely clear – see bars 7-8.

In AI bar 8 is marked as 1ma [volta], after which bar 16 follows, marked as 2[da volta]. However, after bar 8, instead of the expected repeat sign, there is a double bar line. In spite of this inaccuracy, there is no doubt that bars 9-15 are meant to be repetition of bars 1-7. A double bar line appears also after bar 16.

b. 9-18

composition: Op. 25 No 1, Etude in A♭ major

..

In these bars, the abbreviated notation of the repeating figures (see bars 1-8) appears in all three manuscripts: AI, A, and CDP. In the copy, starting from the end of bar 12, it is the use of up to four variants of the repetition sign that draws attention. According to us, the reason could have been the appearance of such signs, different than the ones used by the copyist, in the copied autograph – the first of atypical for CDP signs appears in the same bar in which a similar sign (with two bars) is written in A.

We consider the notation of A in bar 17 to be inaccurate – see the note to this bar.

b. 9-12

composition: Op. 35, Sonata in B♭ minor, Mvt IV

From the middle of bar 9, in Afin only the part of the R.H. is written out. On the bottom stave, Chopin wrote unisono as indication of continuation of the L.H. parallelly with the R.H. The autograph ends together with bar 12.

b. 9-12

composition: Op. 28 No. 20, Prelude in C minor

13 bars in A (→FCGE, →FEEE), #ASch & CGS

9 bars in AB

..

Initially, the Prelude had only 9 bars, which is proven by the footnote in A according to which b. 9-12 were added at the suggestion of certain "Mr. xxx." The Prelude in its initial, 9-bar form can be found in AB, written a year after the entire Op. 28 had been finished.
In A (→FC) the discussed bars are marked in an abridged manner as a repetition of b. 5-8 (mentioning the different dynamics).
