b. 458-459

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

Wedges in A

Dot in GE (→FEEE)

..

In A both c3-ffourths were provided with wedges, which, however, may be problematic at the time of interpreting them. The mark in bar 458 looks like a dot, whereas the one in bar 459 like a crotchet stem of the top note pointing upwards. This is how they were interpreted in GE1 (→FEEE), as a result of which there is no staccato mark in bar 459. In GE2, the dot was preserved in bar 458, yet no staccato mark was added in bar 459, in spite of removing the unnecessary division of the fourth into voices.

b. 458-461

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

2 slurs from 2nd beat in A, contextual interpretation

2 slurs from first beat in GE1 (→FEEE)

3 slurs from 2nd beat in GE2

..

Both slurs in these bars are written in A inaccurately – their endings do not reach the crotchets in bars 459 and 461, although they point to them quite clearly. A comparison with analogous bars proves that they are almost certainly to be interpreted considering not only their position in relation to the bar lines. GE1 (→FEEE) interpreted only the second of them in this way; moreover, both start from the 1st beat in bars 458 and 459, which is a mistake. The division of the slur in bar 460 is an arbitrary change introduced in GE2 (just like in the three previous analogous places).

b. 462-463

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

Slur to c3 in A

Slur to d3 in GE (→EEEE)

..

The slur in the R.H. starting in bar 462 reaches only the last note in this bar in A. It is almost certainly a trace of the original notation, which is supported by an extension of the slur in an analogous situation one bar earlier. Chopin's oversight was corrected already in GE1, most probably by the composer himself. At the same time, the visible traces of corrections in print prove that it was different slurs than in A that were subject to proofreading – it is likely that initially each of bars 461-464 was encompassed with a separate, whole-bar slur (bar 462 certainly was).

b. 462

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

 in A (→GE)

No sign in FE (→EE)

  suggested by the editors

..

The missing  mark in A (→GE) is most probably an inaccuracy, resulting from the transition into a new page. Prior to this place, Chopin wrote a respective sign in an analogous situation three times (bars 414, 422 and 454). The omission of the  mark in FE (→EE) is most probably an oversight.

b. 462-463

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

e3 in A (literal reading→GEFE1)

e3 in A (contextual interpretation) & FE2

e3 & e3 in EE

..

Just like in bars 422-423, the flats lowering e3 to e3 and the cautionary  before e2 in the L.H. in bar 463 prove that the version of A (→GEFE1), interpreted literally, is erroneous. In EE, a respective  is only in bar 463 (together with a  before e2), which is probably a result of an oversight of the sign in bar 462.
