b. 144

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

..

At the beginning of the bar in A (→FEGE1,EE1) there is no  raising c to c. The mistake was corrected in GE2 (→GE3GE4) and EE2.

b. 144-145

composition: Op. 64 No 2, Waltz in C♯ minor

Slur from 5th quaver in A (→FEEE,GE1op,GE1no2)

Slur from 6th quaver in GE2op (→GE3op) & GE2no2

..

Shifting the beginning of the slur to the last quaver in bar 144 is a revision of later GE, most probably in analogy to bars 16-17, in which the editions misinterpreted the notation of FE.

b. 144

composition: Op. 21, Concerto in F minor, Mvt I

..

The cautionary naturals before the f1-foctave are only in FE (→EE), added most probably by Chopin.

Long accent in A

 in GE (→FEEE)

..

Even if we consider the sign of A to be , the editions reproduced it inaccurately, extending it until the 4th quaver. However, the sign in A is almost certainly a long accent – cf. a sign of the same length on the last crotchet as well as a number of others, e.g. in bars 118-120, 125, 133.

Quavers c in A (→GE)

Crotchets in FE (→EE)

Both stems extending the notes were undoubtedly added by Chopin in the proofreading of FE (→EE).
