b. 29-31

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

No slurs in A

Slurs in FE (→EE,GE)

..

The slurs in the R.H. and L.H. in bars 29 and 31 were added in the proofreading of FE1 certainly by Chopin. Similarly in bars 133 and 135.

b. 29-31

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

..

FE (→GE1) overlooked the staccato dots under the 3rd octave in the L.H. in bars 29 and 31 (in the latter the dot was omitted already in A). GE1 also overlooked the dot over the 1st chord in the L.H. in bar 30.

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.

b. 31

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

..

A (→FEGE1) has no rising c1 to c1. The obvious inaccuracy of Chopin's notation was corrected in EE and GE2 (→GE3GE4).
