b. 3

composition: Op. 25 No 8, Etude in D♭ major

..

In A (→GE) and FE there is a superfluous  (cautionary?) before d2. The absence of the sign in EE may be result of a revision.

b. 3-4

composition: Op. 25 No 8, Etude in D♭ major

One slur in A (→GE) & EE

Two slurs in FE

..

The separated slur is most probably a result of an inaccurate reproduction of the manuscript in FE. Cf. bars 7-8.

b. 3

composition: Op. 25 No 8, Etude in D♭ major

..

In the main text we add a cautionary  before e3; the addition was already introduced in GE and repeated in EE3. In GE2 (→GE3) a poorly justified cautionary  was added also before d3 (as well as an erroneous  before the bottom note of the 10th sixth).

b. 3-4

composition: Op. 25 No 10, Etude in B minor

Eight accents in GC (→GE) & EE

Eight  in FE

..

 indications in FE is the original version – in GC one can see that Chopin deleted all of them and replaced them with accents.

b. 3

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

..

In FE1 there is no top note of the chord, d1. The mistake was corrected in FE2; all the remaining sources also include the correct text.
