b.

composition: Op. 2, Variations, complete

..

In the L.H. part, Chopin omitted a few necessary accidentals in AsI and A – a  to band a  to f in bar 327 (yet he wrote a cautionary  to e1) and a  to e2 at the end of bar 328. In GE1 (→GE2,EE1) only the latter was added. In FE and EE2 (→EE3) a  to b was also added, while in FESB – a  to f. All necessary accidentals are present only in GE3. Moreover, in EE2 (→EE3) the  to e1 was repeated before the last quaver in the L.H. bottom voice in bar 328.

composition: Op. 30 No. 4, Mazurka in C# minor

in FC (→GE)

No indication in FE (→EE)

Our variant suggestion

..

As in bar 1, the  indication could have been added to FC by Chopin or removed in the stage of proofreading FE or in [A] after the copy had already been prepared. Due to the above, in the main text we suggest a variant solution.

b. 0-4

composition: WN 55, Waltz in F minor

 
 
 
..

In the majority of the sources, there are two slurs within bars 1-4: the first one spanning bars 1-2, the second - bars 3-4. The beginnings and endings of the slurs were written imprecisely. AR includes one slur spanning bars 1-4. In CY, the absence of the second slur, within bars 3-4, may be considered a copying inaccuracy. Due to the repetition of the cnote at the beginning of the Waltz in AE (→CX) and CC, the first slur begins in the upbeat. A similar situation occurs in CY, however, due to the upbeat, we put the beginning of the slur in the 1st bar, contrary to the notation of the copy.

composition: Op. 29, Impromptu in A♭ major

A (→GE), FE, EE1 differ in the dedication's wording - yet it concerns the same person. The A version does not precise to which of de Lobau sisters the piece was offered. We give the dedication according to the EE1, including full information concerning the dedication's addressee. In EE2 the dedication was removed.
