b. 166-167

composition: Op. 23, Ballade in G minor

Long accents in A

Short accents in FE (→GE,EE)

..

We consider both accents of A, although differing in shape, to be long accents due to their size (cf., e.g. the clearly smaller mark in b. 173). FE reproduced the accents as short (GE and EE did it in an even more pronounced manner).

b. 166-167

composition: Op. 2, Variations, complete

..

In AsI both chords on the 2nd and 3rd quavers in b. 166 are written down in the treble clef, and in both Chopin wrote the bottom note under a ledger line. The mistake was committed in both versions of this bar as well as on the 2nd quaver in b. 167 in 1. volta. At the same time, in the notation of the first of the five discussed chords (2nd quaver in b. 166, 1. volta), there are only two ledger lines, hence the lowest note is g, whereas in the four remaining ones – three ledger lines, which results in e being the lowest note. In the remaining sources, the notation is correct (it concerns 2. volta only, since these sources do not contain a repetition of the second part of this variation).

Dotted crotchet in FE

Crotchet in GE & EE

..

In the case of such a small element as an augmentation dot, put in an atypical place, a double, independent oversight cannot be completely ruled out. However, it seems more likely that Chopin added this dot in the last stage of proofreading FE, after the copies serving as the bases for GE and EE had been sent.

b. 166-167

composition: Op. 12, Variations in B♭ major

..

In FE 3 naturals raising e to e, in various octaves, were omitted – bar 166, the 5th and 10th semiquaver, and the quaver at the beginning of the 2nd half of bar 166. In GE1 only the last two were added, while in the remaining editions – all.
Moreover, in bar 165 it is only EE that feature a  to the 11th semiquaver (c2).
