b. 152

composition: Op. 43, Tarantella

 
 
..

In EE the chord on the second beat in the LH part is a dotted crotchet, while in other sources we find a crotchet and a quaver rest.

b. 152-155

composition: Op. 43, Tarantella

 
 
 
..

In sources bars 152-155 are slurred differently. We see differences mainly in the first half of the phrase.

Given it is a grace notes phrase we may assume GE to be the copyist's arbitrary interpretation.

Similarly, EE version with a slur beginning in the middle of b. 154 also seems little probable.

b. 152-154

composition: Op. 39, Scherzo in C♯ minor

..

The manner in which the indication rallentando is written is slightly different in different sources. EE has the abbreviation rallent. broken into syllables, which is an arbitrary manner typical for that edition. In FE, the abbreviation rall. was used, and in GE the dashes delimiting its scope were omitted.

Short accents in EE

Long accents in GC (→GE) & FE

..

GC and FE clearly have long accents, EE – short ones. The marks in GE are unclear - shorter than those in bar 131 or 147, yet longer than those in bar 139. We assume them to be long accents, just like it was done in GC.

b. 152-165

composition: Op. 42, Waltz in A♭ major

Slur in FE0

Long slur in FE1

Four slurs in FEG (→GE1)

Four slurs in EE

Five slurs in GE2 (→GE3)

..

The slurring in bars 159-164 is clearly incomplete in FE0, which may be a result of Chopin's inaccuracies in [A], errors of the engraver or both. Chopin then changed and completed the slurs in FEG, the base text to EE and proofreading of FE1, yet in all of them differently. In total, it gives three different authentic slurring versions. In the main text we give the version written by Chopin's hand in FEG (→GE1), as in the case of FE and EE, there is a slight possibility that Chopin proofreading was overlaid with certain mistakes, manners or revisions of the engravers.
It is not entirely clear what the motivation of the reviser of GE2 (→GE3) was at the time of breaking the slur between bars 159 and 160.
