b. 204

composition: Op. 12, Variations in B♭ major

..

In FE the last L.H. chord is provided with a superfluous  to b. On the other hand, the accidental to d1 is missing, which suggests a mistake, particularly in the context of the next two bars. This is how it was assessed in GE, in which the  to b was removed, while a flat to d1 was added, lowering it to d1. The mistake was also corrected in EE by adding the correct accidental yet without removing the harmless  to b.

b. 205

b1 in chord in GC (→GE) & FE2 (→EE,FE3FE4)

Octave without b1 in FE1

..

No b1 in the chord is most probably a result of an oversight of the note by the engraver of FE1. The mistake was corrected already in FE2.

b. 205

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

GE1 overlooked the part of the R.H. slur falling on this bar. The mistake was corrected in GE2.

b. 205

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

No slur in A, probable interpretation

Slur end in A (possible interpretation) & GE (→FEEE)

..

The slur, written in A in previous bars, when interpreted literally, does not exceed bar 204. However, the notation is ambiguous, so the slur reaching the beginning of this bar can be considered an alternative interpretation of A. The version with the slur ending in bar 205 is included in all editions.

b. 205

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

No slur in A & GE2

Slur in GE1 (→FEEE)

..

The slur, added in GE1 (→FEEE) may be a result of Chopin's proofreading. However, according to us, an erroneous interpretation of the tie of e1, overlooked in GE1, is more likely.
