Issues : Accidentals in different octaves

b. 416-423

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

..

In FE, there are no sharps before the second semiquaver, placed an octave lower than the first one, of the majority of the figures in the L.H. – marks are necessary in 10 out of 15 figures, whereas an appropriate  is present only before c​​​​​​​1 in bar 418. All the remaining marks were added both in GE and EE.

b. 424

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

..

In the sources, there are no sharps before the d2 and d​​​​​​​3 semiquavers. It results from a different rule of validity of accidentals from the one applied generally in contemporary editions where a part of a bar is written with the use of an octave sign. In Chopin's times, a mark next to a note encompassed with an octave sign was often considered valid also for a note written at the same pitch, yet not encompassed with an octave sign.

b. 425

..

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.

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.
