b. 220

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

 above staff in A

 between staves in GE

No mark in FE (→EE)

..

Same as in the previous bar, the  sign was moved to between the staves and slightly shifted (this time to the right). The absence of the sign in FE (→EE) can be explained by an oversight; however, it cannot be excluded that Chopin removed the hairpin as a part of the proofreading of the part of the L.H. According to us, even if it were Chopin's proofreading, it did not concern the sign written in A, applying only to the part of the R.H.

b. 220-225

composition: Op. 16, Rondo in E♭ major

No pedalling in FE (→GE,EE)

Pedalling suggested by the editors

..

We consider the missing pedalling in FE (→GE,EE) in bars 220-225 to be an inaccuracy of notation, even though it was probably omitted by Chopin himself. We suggest adding markings patterned after the analogous bars 52-54, 231 and 56-57 (we include markings from bar 231 instead of the most probably inaccurate pedalling of bar 55).

FEH includes here two diagonal crosses – characteristic marks of Chopinesque teaching. Each time, their meaning remains in the sphere of more or less justified speculation.

composition: Op. 22, Polonaise

Just like in b. 76, the dyad of the bottom voice (e1-a1) in FE is a crotchet. The patent mistake was corrected both in GE and EE.
