b. 4

composition: Op. 23, Ballade in G minor

..

In the main text we omit the additional slur over the triplet entered into A – cf. General Editorial Principlesp. 16. The slur was omitted (removed?) already in FE (→GE,EE). In the next bar, Chopin omitted such a slur already in A.

b. 4

composition: Op. 2, Variations, complete

in A (→GE1EE1)

F in GE2 (→GE3,FESB), FE & EE2 (→EE3)

..

We consider the version of A (→GE1) to be erroneous, which is indicated by the orchestral part – an F in cellos and double basses is both in the later version of AsI and in the voices of GE and FE. The correct version of FE almost certainly resulted from Chopin's correction, probably introduced still into the copy of GE1 serving as the basis for that edition – there are no visible traces of changes in print. The corrections present in GE2 (→GE3,FESB) and EE2 (→EE3) can be considered revisions on the basis of orchestral parts. In the case of GE2, Chopin's intervention is also likely; his participation in the preparation of that edition is generally questionable, yet it cannot be excluded to a limited extent.
In the basic version of AsI, which is an earlier edition of this orchestral introduction, neither of these versions can be used.

b. 4

composition: Op. 30 No. 2, Mazurka in B minor

..

The cautionary  to a1 is present only in FE (→EE), perhaps added by Chopin in the stage of proofreading FE. In the main text we also add a  to a in the L.H.

Short accents in FC (→GE) & FE

Vertical accents in EE

..

The use of vertical accents (unauthorised by Chopin) – instead of common, short horizontal accents in bars 4 and 8 – is a frequent phenomenon in first English editions.

b. 4

composition: Op. 63 No. 2, Mazurka in F minor

Slur to c2 in FE (→GE,EE)

Slur to f2 suggested by the editors

..

The slur only reaching the semiquaver c2, musically and pianistically awkward, may be the result of a misreading of [A], perhaps inaccurate in this respect. That's why we propose a longer slur in the main text. The same in bar 44.
