b. 107

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

Minims d2 in GC (→GE), EE1 & EE3

d2-f2 in FE & EE2

..

The version of FE is a result of proofreading of this edition – Chopin added f2 minims to the d2 minims, present in the remaining sources (except for EE2, in which the version of FE was introduced). Being the latest, we adopt it to the main text.

b. 107-108

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

5 long accents in GC, FE & EE

6 long accents in GE1

6 short accents in GE2 #→GE3)

..

Same as in bars 5-6, stating which kind of accents Chopin had on his mind poses a difficult challenge. In GC, FE and EE the last accent in bar 108 is clearly shorter than the previous (and next) and this is the version we give in the main text. The harmonised notation of GE1 and GE2 (→GE3) may be, however, considered as justified alternative versions of these signs.

b. 107-108

composition: Op. 64 No 3, Waltz in A♭ major

 in A

 in FE (→EE)

No sign in GE

..

The moment of the beginning of the  sign in A is unclear. We assume the top arm, written first, to be reliable. In FE (→EE) the sign starts from the beginning of the bar, which may be considered an alternative interpretation of A, however, the fact of shortening the sign is a patent inaccuracy of the engraver. The missing hairpin in GE is probably an oversight or a proof of the fact that the sign was added only in the last proofreading of FE.
