b. 73-77

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

d1-e1 in A (→FEGE) & EE2

d1-e1 in EE1

c1-e1 suggested by the editors

..

In the last chord in bars 73 and 77 in the main text we change enharmonically d1 to c1, considering Chopin proofreading of FE in bar 69 to be valid also in this place. EE1 erroneously swapped the accidentals in this chord ( was placed before d1, whereas  before e1). Actually, the sound of the resultant chord does not raise any doubts, yet the notation with the use of two superfluous accidentals is a proof of a patent mistake.

GE2 (→GE3GE4) and EE2 added a cautionary  next to d1 in the chord at the beginning of bars 74 and 78. The addition is justified only when preserving the original orthography of the last chord in bars 73 and 77.

b. 76

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

..

We removed superfluous sharps (cautionary?) placed in A next to in bar 76 and a1 in bar 86. All editions had a similar approach. The deletions visible in A show that this kind of superfluous sharps were initially written in A still in bars 72, 79-80 and 84. See also bars 99-100
