b. 256-260

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

..

In the part of the L.H. neither the clef was changed to the treble one in bar 256 nor the bass clef returned at the end of bar 260 in A. These patent oversights – particularly taking into account the orchestral part of Morch with the constantly held G major chord – were corrected already in GE1 (→FEEE, →GE2).
The treble clef written in pencil in bar 256 is probably a later, foreign addition – cf. a similar situation in the 2nd mov. of the Concertobar 50

b. 257-260

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

..

In A there is no  lowering g1 to gin bar 257 and both necessary flats in bar 260. The signs in bar 260 were added already in GE1 (→FE), whereas all three flats are included in EE and GE2.

e3 on 2nd beat in A (→GEFEEE), contextual interpretation

Our alternative suggestion

..

Comparison of the piano part in A (→GEFEEE) with the orchestral part of Morch gives rise to the suspicion that there is a mistake, due to a non-simultaneous introduction of an altered fifth of the G major chord (written by Chopin as e):
.

It appears at the beginning of the bar in the 2nd violin part and on the 2nd beat of the bar in the R.H. with unchanged d2 and d1 in the L.H. ReF shows that the mistake was committed in Morch – the 2nd violin should have f1 instead of e1.
The notation of the trill on eshall be also completed, since the necessary accidental specifying the top note of the trill is missing over it.

An alternative version suggested by us allows to achieve an even smoother harmonic sound, at the expense of a small modification of rhythm and pedalling.

No accidental in sources

 suggested by the editors

..

In the main text we add a cautionary  before d1. The need for such an addition does not stem from the notation of the sources, yet in some popular collective editions the note was changed to ddue to the erroneous ein the orchestral part.
