b. 425

composition: Op. 11, Concerto in E minor, Mvt I

Slur in FE (→GE)

2 slurs in EE

..

Chopin would sometimes use the notation with double slurs, e.g. in the Concerto in F minor, op. 21, 3rd mov., bars 472-480, yet in this case, the addition of the top slur must be a revision of EE.

b. 425

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE (→EE), the  before the last semiquaver was overlooked, which was corrected in GE. Moreover, instead of a  before the 8th semiquaver (c​​​​​​​2) the majority of the sources (except for GE3) feature a respective mark on the 5th semiquaver. It is related to the use of an octave sign to write the 1st beat of the bar.

In the main text, we omit the unjustified  before f​​​​​​​2,, present in all sources.

b. 425-426

composition: Op. 31, Scherzo in B♭ minor

c1 tied in A (→FC, →FEEE) & GE2 (→GE3)

c1 repeated in GE1

..

The lack of a tie to c1 in GE1 is undoubtedly an error resulting presumably from an inaccuracy in FC which has this tie only in b. 426 (on a new staff). The tie was added in GE2 (→GE3). See also b. 424-425.

b. 426-428

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

..

It is only GE2 that includes a natural before b2, the 4th quaver in bars 426 and 428; however, due to the use of an octave sign, we consider the sound of this note to be specified also in the remaining sources.
