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.
