b. 256

composition: Op. 2, Variations, complete

..

In the manuscripts there are no accidentals in the second triplet (on the 3rd beat of the bar). In the main text we include both added flats – perhaps by Chopin in GE (→FE,EE) – although it is only the  restoring a1 that is indispensable. Incidentally, also in the previous triplet, an octave higher, the  to g2 present in all sources is also of a cautionary nature.

b. 256

composition: Op. 2, Variations, complete

Shorter slurs in Af

Various slurs in A

Longer slurs in GE (→FE,EE)

..

In the main text we reproduce the clearly written slurs of A, although it is uncertain whether by differentiating the range of these slurs Chopin really wanted to suggest a detail of articulation. Both remaining, unified versions of slurring can be regarded as equivalent variants.

composition: Op. 49, Fantaisie in F minor

No signs in sources

Arpeggio signs suggested by the editors

..

As in analogous bars 172-173 and 176-177, in the main text we suggest adding arpeggio marks to the tenths on the basis of the arpeggios added by Chopin while proofreading FE1 in bars 85-86 and 89-90.
