In [A] (→FE1→GE) Chopin wrote the middle section of the Mazurka in a key signature with four flats, although the prevailing key is D major, while from bar 41 even G major. Chopin corrected the key signature in FE2 (→EEW). Such discrepancy between the key signature and the prevailing key happened to Chopin in the Mazurka in G minor, Op. 33 No. 1, which both in the manuscripts and the editions is written down with 4 sharps.
