b. 149

composition: Op. 35, Sonata in B♭ minor, Mvt I

Slur in GC, FE (→EE) &GE2

No slur in GE1

..

The missing slur in GE1 is surely an engraver's mistake, corrected in GE2.

b. 149

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In GE1, almost certainly due to the engraver's inattention, the pedal release marking was omitted. The mistake was corrected in GE2.

b. 149

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

Slur from 1st crotchet in A (literal reading→GEFEEE)

Slur from octave in A (contextual interpretation) & FED

..

The slur of A, when interpreted literally, seems to start from the beginning of the bar and this is how it was reproduced in the editions. However, both the previous slur, led to the beginning of this bar, and con duolo placed only over the second crotchet suggest that the new musical thought should begin just from the second crotchet. The intuition is confirmed by the Chopin entry in FED, in which the ending of the slur added over the roulade in bar 148 clearly separates the gcrotchet from the further course of music.

b. 149-150

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

Separated slurs in A & GE2

Contiguous slurs in GE1 (→FEEE)

..

In A, the slur led to the minim in bar 150, uncommonly unambiguously – as for a transition into a new page – was, however, totally falsely reproduced in GE1 (→FEEE). It is possible that the engraver first took care of the slur in bar 149, which he considered to be whole bar long, just moved to the right. Then he combined both slurs in bar 150, seeing a whole in them, inaccurately written (both slurs reach quite far into the space between the initial minim and the following it quaver, which could have suggested such an interpretation). In the last slur, he also performed the idea of a continuation from the previous bar, without touching the already finished slur in bar 149. GE2 interpreted here the slurs of A more literally and undoubtedly rightly so.

No marking in FED, possible reading

..

In FED is crossed by a slightly diagonal line, which can be interpreted as a deletion. However, the meaning of the dash is not certain – in Chopin pupils' copies, there are fragments containing such delicate dashes, drawn probably when discussing problematic places for the pupil. Most frequently, the dashes are of no specific meaning; they simply prove a more intense work on a given fragment.

It is also unclear what a possible deletion could mean. If not  then ? Or maybe  that was valid before the said ? In the face of these doubts, we suggest the absence of , being a result of a possible deletion, only as one of possible interpretations of FED
