b. 53

We add a cautionary  before b in the main text.

b. 53-56

composition: Op. 63 No. 1, Mazurka in B major

..

In AI, in each of these bars, Chopin wrote a  (cautionary?) to a. The fact that this unnecessary accidental was repeated a few times suggests that the composer was uncertain about the presence of the  raising a in the key signature of the B major/G minor keys. Cf. the Etude in G minor, Op. 25 No. 6, bars 7-8.

 in AI is one of many signals that the original Chopinesque concept of the middle section of the Mazurka was evidently more subdued, delicate and with a smaller number of contrasts than the final one.

Tie in AI & EEW

No tie in FE (→GE,EEC)

..

The missing tie to f in FE is almost certainly an oversight (by the engraver or by Chopin in [A]). In EEW a revision was performed, probably on the basis of a comparison with bars 57-60 and 61-64, in which both g and c1 are sustained for 4 bars.

No A in AI

The version of AI was eventually abandoned when Chopin prepared the Mazurka for print. However, the deletions visible in the manuscript suggest that the latest version (with quavers only) was at the same time the earliest one, since it was this version that Chopin most probably wrote first; only then did he change it to a version with a crotchet on the 2nd beat of the bar.
