b. 63-64

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

..

The notation of AI shows the evolution of the accompaniment in these bars. In both bars Chopin started from a typical bass-chord-chord structure, which he modified in b. 64 by replacing the last chord with a transitional F note. At the same time, he was improving the pitch of the bass notes, which he initially wrote as B and e and then moved them an octave lower (B1 and E); eventually, he left B and E. The way the changes are written is typical of drafts: gentle crossings-out or even leaving two versions with none of them having been crossed out. Therefore, it seems that they were introduced at a time when it was already known that the Mazurka had to be rewritten, hence AI could be used to write down new ideas on the go. The corrections/additions in the next three bars are of similar nature: b. 65 and 67 in the R.H., b. 66 in the L.H.
In b. 64 the same two versions that we can see in AI are also written in AF, whereby the earlier one is definitely crossed out. According to us, it proves Chopin's reduced concentration at the time of writing another autograph of the Mazurka.

b. 82-85

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

..

There are visible crossings-out of the original versions of the 2nd crotchet in b. 82 and 85 in AF. It is another clue that Chopin was distracted while writing this fragment (b. 81-88 were initially overlooked and then added on the staves drawn in the side margin).

Crotchets in AI

Quavers in AF (→FEEE) & GE

..

The melodic variants in b. 85 and 87 of the motif opening the majority of the phrases of this theme were introduced only just at the stage of writing Stichvorlage autographs. Such a diversification of recurring motifs is typical of Chopin and would frequently appear in the final stages of shaping particular pieces, cf., e.g. the Mazurka in G Minor, Op. 24 No. 1, b. 57 and 59.
The layout of the melody's notes in b. 85 in AF shows that the a1 quaver was added there to the g1 note, which was initially a crotchet. At the same time, Chopin forgot about the  before this note, which was corrected in FE (→EE).

Triads in AI

Sixths in AF (→FEEE)

Sixth & triad in GE

..

The version of AI with triads is the original one, left almost certainly by inadvertence. Its traces can also be seen in AF, in which, however, Chopin changed both chords – differently than in all analogous bars – to sixths. According to us, the change of the chord on the 3rd beat of the bar could have been a mistake; therefore, in the main text we give the unequivocal version of GE, which is compliant with the remaining analogous places.

New slur from 1st quaver in AI

Continuous slur in AF (→FEEE)

New slur from 2nd quaver in GE

Overlapping slurs suggested by the editors

..

In AF one can see a correction of slurring in this place – the slurs, initially separated by a bar line (like in AI), were then combined. According to us, hesitation about the range of these slurs, visible in this and analogous places (b. 8-9), does not allow us to consider this correction to be final, since Chopin corrected only one of the versions of the divided slurs. In addition, in b. 8-9 the same slurring was probably corrected by Chopin in a different manner, although actually resulting in the same effect. Taking into account the above, in the main text we give the version that was corrected later. The versions of FE and GE may be considered equal variants.
