b. 236-237

composition: Op. 21, Concerto in F minor, Mvt III

Continuous slur in A (→GE1, contextual interpretation)

Separate slurs in FE (→EE) & GE2

..

In GE1, the slur in bar 236, at the end of the line, indicates continuation, which, however, is not confirmed by the slur in bar 237. This ambiguous notation was interpreted contrary to the notation of A both in FE (→EE) and GE2. It is worth observing that the compliance of the slur of GE1 in bar 236 with A is a result of intense proofreading – originally, the entire line (bars 232-236) was provided with one-bar slurs. At the same time, the traces of the changes in bars 235-236 became so visible over time that GE1a was reengraved in this place. The oversight of the dashes marking the range of validity of the octave sign at the end of bar 236 was a side effect of this retouch.

b. 243

composition: Op. 21, Concerto in F minor, Mvt III

..

In FE the last chord has a quaver stem. The absence of rest, required if the chord was shortened, proves that it is a mistake, probably stemming from a misunderstanding at the time of implementing extensive proofreading of pitch and rhythmic values in bars 243-244.

A has an aas the last note in the L.H. It is almost certainly a mistake – cf. analogous figures in bars 300, 302 and 304-306. Mistakes in the number of ledger lines are the most frequent pitch errors committed by Chopin (excluding those related to the notation of accidentals). GE (→FEEE) features the correct text, which can be ascribed to Chopin's proofreading or a fortunate mistake, since there are no visible traces of correction in print, whereas the note in A, despite three ledger lines, is written lower than the previous g1.
In the discussed place, there is a visible correction in A. The deletions are actually very precise, yet their placement allows us to indicate e1 and das possibly crossed out original (or only erroneous) last two notes.

No c2 in chord in A (→GE)

c2 in chord in FE (→EE)

..

An additional cin the chord must be a mistake, since the note does not result from the link to the previous chord; it unnecessarily precedes the next, accented minim. We are most probably dealing with an unfinished proofreading of a major mistake – the traces of removing cvisible in this place in FE may indicate that it was the 1st chord from the previous bar, c2-f2-c3, that was printed here in the first place. While proofreading this mistake, both missing notes were added (f1-a1), but it was only c3, going beyond the target chord, hence easier to remove, that was deleted.

e2 in chord in A (→GE1FEEE)

e2-f2 in GE2

..

Originally, the 2nd crotchet in the bar in A was a c2-f2-c3. Chopin changed the middle note from f2 to ein the last phase of reviewing A (→GE1FEEE). The version of GE2 is a result of an erroneous interpretation of this correction.
