b. 142-144

composition: Op. 22, Polonaise

No marks in FE (→GE)

Accents in EE

..

Propagating the accent from b. 145 to the three previous seemingly similar situations is an arbitrary revision of EE, disregarding the harmonic context. See also b. 134-137.

b. 142-145

composition: Op. 50 No. 3, Mazurka in C♯ minor

No indication in AF (→FEEE)

cresc. in GE

..

The cresc. indications in b. 142 and 145 most probably come from [AG] (→GE). One could assume that in the autograph the indications were overlaid on a hairpin –  – a combination Chopin would willingly use.

b. 142-144

composition: Op. 44, Polonaise in F♯ minor

No markings in GE

Pedalling in FE (→EE)

..

The pedal markings of FE (→EE) in b. 142 and 144, whose authenticity cannot be denied, were most probably entered by Chopin into the basis for FE. It is indicated by the trace of correction visible in analogous b. 162 where the  sign was moved one beat earlier in print – its initial misplacement was probably due to misinterpretation of the manuscript.
In the main text we place the second  sign analogously to the first. In FE it is clearly printed too far.
Similarly complemented pedalling can also be seen in FE (→EE) in bars 201-204 and 221-223.

b. 142

composition: Op. 2, Variations, complete

..

In A the last fingering digit in the 1st half of the bar concerning the R.H. (over f2) is 3, whereas GE1 printed there a 2 (by mistake). The mistake was corrected in all editions based on GE1 – in GE2 (→GE3) and FE the digit 3 was restored, while in EE the erroneous digit was removed.
