b. 190-191

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

New slur in GC (literal reading) & FE (→EE)

Slur continued in GC (interpretation→GE)

..

Providing bar 191 with a separate slur can be an echo of the original slurring (cf., e.g., the slurs in bars 45-48). The notation of GC suggests that the slurs could have been combined by Chopin in [A], which was misunderstood in FE (→EE).

b. 190

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

in A (→GE)

No marking in FE (→EE)

..

The omission of  in FE (→EE) could have been a result of Chopin's proofreading, and it was almost certainly accepted by him.

b. 190

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

..

In A there are no naturals raising d to dB1 to B1 and d2 to d2. The first two were added already in GE1 (→FEEE, →GE2), the third one – only in EE.

Our alternative suggestion

..

There are no doubts that the  sign written in A marks also an accent, emphasising the beginning of an enhanced variant of the phrase heard two bars earlier. Therefore, we suggest an alternative interpretation of this sign as a long accent.

b. 190-192

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

Slur in bars 190-191 in A & GE2

Slur in bar 191 in GE1 (→FEEE)

Slur in bars. 190-192 suggested by the editors

..

According to us, ending the slur on the last crotchet in bar 191 is an inaccuracy of the notation of A – cf. the longer slur in the L.H. as well as the slur over a similar phrase in bars 188-190. Starting the slur in GE1 (→FEEE) only from bar 191 is an example of a characteristic manner of the engraver of GE1. See also bars 192-194
