Main


b. 148

composition: Op. 50 No. 3, Mazurka in C♯ minor

No sign in AI & AF (→FEEE)

in GE

..

In the main text we give the  mark after GE, which most probably reproduce the notation of [AG].

b. 149-152

composition: Op. 50 No. 3, Mazurka in C♯ minor

1-bar pedalling in AF (→FEEE)

2 pedals in GE

Our variant suggestion

..

In the main text we include the changes of pedal under b. 149-150 and 151-152, present only in AF (→FEEE), in a variant form. When choosing one of the versions, it is also the variants of dynamic indications that should be taken into account – in the sources the shorter pedalling markings are associated with more precise dynamic indications.

b. 149-151

composition: Op. 50 No. 3, Mazurka in C♯ minor

..

In b. 149 and 151 the autographs are devoid of cautionary accidentals. In the first stage of proofreading of FE (→EE) a  was added before b in b. 151; the accidental is also present in GE. In the second stage of proofreading of FE before b was also added in b. 149; moreover, a  was repeated before the R.H. b note on the 3rd beat of the bar.
We include both naturals in the main text.

b. 150-153

composition: Op. 50 No. 3, Mazurka in C♯ minor

No markings in AI & GE

   in AF (→FEEE)

Our variant suggestion

..

It is difficult to say whether Chopin forwent the contrasting dynamic indications in b. 150 and 152-153 entered into AF (→FEEE) while writing [AG] (→GE) or whether they were added later, after [AG] had already been written. Therefore, in the main text we leave it to the discretion of the performer whether to include them or not.

b. 153-154

composition: Op. 50 No. 3, Mazurka in C♯ minor

Pedal in bar 153 in AF (→FEEE)

Pedal in bars 153-154 in GE

Our variant suggestion

..

Chopin was consistent in writing shorter pedalling in AF (→FEEE) – cf. b. 149-152. The notation adopted in the main text should be understood as variant, i.e. the pedal released at the end of b. 153 or only just in b. 154.
