b. 89

composition: Op. 30 No. 4, Mazurka in C# minor

No c1 in chords in FC (→GE)

Chords with c1 in FE (→EE)

..

A comparison with analogous bar 73 suggests that the version of FC (→GE) is erroneous. It is likely that Fontana did not notice both c1 notes in the chords due to inaccurate notation – in Chopin's autographs, it can sometimes be difficult to determine the presence of notes on ledger lines in the middle of chords. A correction to FC (in print or of the basis) cannot be ruled out either.

b. 93-94

composition: Op. 30 No. 4, Mazurka in C# minor

No markings in FC (→GE)

Pedalling in FE (→EE)

..

As in analogous bars 77-78, Chopin most probably added the pedal markings while proofreading FE.

b. 94

composition: Op. 30 No. 4, Mazurka in C# minor

..

FE (→EE) feature here an f1-g1 second, twice (as in the previous bar). The mistake was corrected in FED, perhaps by Chopin.

b. 96-97

composition: Op. 30 No. 4, Mazurka in C# minor

c1 repeated in FC (→GE)

c1 tied in FE (→EE)

Our variant suggestion

..

Both versions may be authentic, and both are musically justified. From the pianistic point of view, repeating c1 seems more natural; on the other hand, the tie could have been overlooked by the copyist due to inattention. Taking into account the above, in the main text we suggest a variant solution.
