b. 103-104

composition: Op. 38, Ballade in F major

Slur to a in A (→FE)

Slur to c1 in GC (→GE)

Slur to to d in EE

..

We give the range of slur according to A (→FE). The notation in GC (→GE) is inaccurate, and in EE probably revised in order to avoid a note without slur.

b. 103

composition: Op. 22, Polonaise

..

In EE the last semiquaver of the 1st beat of the bar is written down as F. In the penultimate stage of proofreading of FE (→GE), Chopin decided to change the notation to enharmonically equivalent G (traces of a correction performed in print are visible in FE).

b. 103

composition: Op. 50 No. 1, Mazurka in G major

 on 3rd beat in FE (→EE)

 on first beat in GE2

..

 under the 2nd quaver is both in A1 and GE1, which proves that it is not an inaccuracy, but a precise indication on how to preserve the G1 bass note with a pure G major chord. In the remaining sources, the mark was moved due to carelessness or due to an attempt at correcting the allegedly inaccurate notation of A1: in FE (→EE) it was moved under the 3rd beat of the bar, whereas in GE2 to the beginning of the bar.
