b. 12-20

composition: Op. 50 No. 2, Mazurka in A♭ major

..

The cautionary flats before a1 in b. 12 and 20 were added in the first phase of proofreading of FE (→EE). It is unclear whether Chopin was responsible for the entire process of that phase of proofreading.

b. 16

composition: Op. 50 No. 2, Mazurka in A♭ major

..

In the main text we add cautionary flats before e2 and e1. The latter was already added in the proofreading of FE (→EE), although one cannot be certain whether such additions come from Chopin.

b. 19-20

composition: Op. 50 No. 2, Mazurka in A♭ major

No pedalling in A1 (→FEEE)

Pedalling in GE

Our variant suggestion

..

Due to the following reasons, in the main text we include the pedalling of GE in a variant form only:

  • the  asterisk in b. 19 is almost certainly misplaced;
  • harmonic pedalling is not necessary here, since the notes forming part of the harmonic base are held with fingers.

There is a similar situation in b. 50-51 and 94-95.

b. 20-25

composition: Op. 50 No. 2, Mazurka in A♭ major

..

In b. 20 and 25, GE included upper voice rests on the 1st beat of the bar. Formally necessary, such rests often do not provide any useful piece of information in piano music notation, hence they were not used by Chopin. Therefore, it is highly likely that their presence in GE is a result of a revision.

b. 23

composition: Op. 50 No. 2, Mazurka in A♭ major

in A1 (→FEEE)

Grace notes in GE

..

In the main text we adopt the notation of the principal source, i.e. GE, undoubtedly repeated after [A2]. It is unclear what Chopin's motivation was when he changed the  mark to a double grace note in this particular place, hence both manners of notation are considered equal. The same applies to b. 54 and 98.
