b. 147

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

Slur under sextuplet in A

Phrase mark in GE (→FEEE)

..

The slur under the sextuplet, visible in A, was replaced with a phrase mark of a greater range in GE (→FEEE) (the inaccurately engraved ending of this slur was corrected both in FE and GE2). The visible traces of corrections show that initially the slur started already from the dquaver. The last correction was certainly performed by Chopin; it cannot be excluded that the very addition of the slur was inspired by him.

b. 147-148

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

cresc. - - in A

No indication in GE (→FEEE)

..

The missing cresc. - - is certainly a mistake of GE (→FEEE), perhaps caused by sempre più stretto having been placed between the staves, hence in a place where cresc. should be.

b. 147

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

No mark in FE (→GE,EE)

[] suggested by the editors

..

In the main text, we suggest adding a long accent after the accents in the two previous bars, particularly after the strictly analogous one in the R.H. part in bar 145. All three bars were provided with accents added in FEH, which may reflect lessons with Chopin.
