b. 151

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

No slurs in A

Different slurs in GE1

Slurs from 2nd quaver in FE (→EE)

Slurs from first quaver in GE2

R.H. slur form first quaver suggested by the editors

..

The missing slur in the R.H. is almost certainly an inaccuracy of A: in the entire fragment, Chopin marked articulation of all remaining notes. In GE1 slurs in parts of both hands were added, which could have been performed upon initiative of Chopin. However, the proofreading was implemented inaccurately, since the range of the added slurs differs, which could not correspond to the composer's intention (the slurs were unified both in FE (→EE) and GE2, although in each differently). There is also a possibility that Chopin added only the slur in the R.H. and the second one is an addition of revision – cf. bars 148 and 154. Therefore, in the main text we give only the slur in the R.H. – see bars 145-160.

A (→FE1) has no accidentals in this bar. Chopin added the overlooked naturals before the 3rd L.H. octave (B-b) in GC (→GE) and FE2 (→FE3). The signs were also added in EE, most probably by analogy with bar 149.

All sources feature a quaver at the beginning of the bar, as a result of which the bar includes 13 semiquavers. It cannot be excluded that the mistake was already in [A].

b. 151

composition: Op. 44, Polonaise in F♯ minor

..

There is no cautionary  to f2 before the 1st R.H. quaver in FE (→EE1) and GE. In this context it is a patent inaccuracy (probably by Chopin) – two cautionary accidentals are present in all sources both 2 bars further and in the first phrase of this section, in b. 131, 133 and 135. The accidental was added in EE2 (→EE3).
Moreover, in FE (→EE1) there is no  raising d2 to d2. The mistake was corrected in EE2 (→EE3).
