Pitch

b. 61

composition: Op. 30 No. 2, Mazurka in B minor

g-c1-f1 in FC (→GE)

c1-f1 in FE (→EE)

..

As in bar 29, the version of FE (→EE) is most probably a mistake, since there are no reasons to differentiate bar 53 from bar 61. In FC the note was added – probably by Chopin – which is evidenced by the fact that the stem of this chord was being extended.

b. 64

composition: Op. 30 No. 2, Mazurka in B minor

FC (→GE)

FE (→EE)

..

This is the most significant difference between the authentic sources – FC and FE – in entire opus 30. The FE (→EE) version, which is a clear improvement of the Mazurka ending, must have been introduced by Chopin in the proofreading of or in the basis for FE instead of the FC (→GE) version.
