No note f in A

Note f in FE (→GE,EE)

In bar 21, the staccato dot, present in A over the 1st octave in the L.H., was misinterpreted in FE (→GE,EE) as an additional note, which was annexed to the sixth in the R.H. Cf. bar 125.

b. 28

composition: Op. 26 No 2, Polonaise in E♭ minor

..

A (→FEEE1) lacks  rising c1 to c1. The obvious Chopin's imprecision was corrected in GE and EE2, as well as in FES which displays  written in probably by Chopin himself.

b. 30

composition: Op. 26 No 2, Polonaise in E♭ minor

..

In FE1 there is no  next to b2. Moreover, A (→FE1GE1) has no  before the first e1 in the L.H. It seems even that in A Chopin cancelled that sign probably considering valid the earlier  in the R.H. Remaining editions have these inaccuracies corrected.

In the main text we omit the superfluous  added in FE (→GE1GE2) next to the last in the bar.

b. 31

composition: Op. 26 No 2, Polonaise in E♭ minor

..

Cautionary flats before B1-B and b2 were added in FE2 (→EE). Chopin's participation cannot be excluded, although an editorial revision also seems possible. GE2 (→GE3GE4) added four signs – before b1 as well.
