b. 1

composition: Op. 28 No. 16, Prelude in B♭ minor

 in A (→FCGE)

 in FE (→EE)

..

The change of time signature in FE probably resulted from the engraver's inattention. In Chopin's pieces, it was common that engravers did not differentiate between  and , see the Prelude No. 14 in E Minor.

composition: Op. 28 No. 18, Prelude in F minor

 in A (→FCGE)

..

The  marking present in FE (→EE) instead of the authentic  indication must have resulted from the engraver's carelessness – see the Prelude in E minor no. 14.

b. 1-6

composition: Op. 28 No. 18, Prelude in F minor

4 slurs in A (→FC) & EE2

Slurs in b. 1, 2, 6 in FE

Slurs in b. 1, 2, 5 in GE

Slur in b. 6 in EE1

..

None of the editions based on manuscripts reproduced all 4 slurs over the pairs of chords in bars 1-2 and 5-6. EE1 overlooked yet 2 out of 3 slurs in FE. The complete set of slurs in EE2 results from a compilation of the slur of EE1 with the slurs reproduced from GE1.

b. 1-2

composition: Op. 28 No. 8, Prelude in F♯ minor

..

FE erroneously gives d instead of c as the last L.H. quaver in each of these bars. The errors, caused probably by this note in bar 1 being written somewhat imprecisely in A (bar 2 is marked as a repetition of bar 1 in the manuscripts), were corrected in FE2 (→EE).

b. 2

composition: Op. 10 No 2, Etude in A minor

..

In the middle of the bar in FEcor there is no  raising c3 into c3. This obvious mistake was corrected by Chopin in one of the later proofreadings.
