b. 221

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

c3 in GC (→GE)

No c3 in chord in FE (→EE)

..

Same as in bar 219, the absence of the c3 note in the 2nd chord is certainly an oversight of the engraver of FE (→EE).

b. 221

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

No slur in A (→GEFE)

Slur in EE

..

The missing slur embracing the group of small notes is to be, according to us, regarded as an inaccuracy. Therefore, in the main text we give the slur – analogous with bar 219 – added in EE.

b. 221

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

Repeated octave in A (→GE)

Tied octave in FE (→EE)

..

The sustained F-f octave is the latest version, introduced by Chopin in the proofreading of FE (→EE).

b. 221

composition: Op. 16, Rondo in E♭ major

g in FE (→GE,EE)

e​​​​​​​ suggested by the editors

..

It seems unlikely that Chopin would have wanted to change here a fixed accompaniment scheme with E, e and B​​​​​​​ notes as the ostinato bass figure. Therefore, the g note featured in the sources as the 2nd quaver is almost certainly a typical Terzverschreibung mistake.

b. 221

composition: Op. 11, Concerto in E minor, Mvt I
