Issues : Accidentals in different octaves

b. 335

composition: Op. 2, Variations, complete

..

As in the entire Variations, while writing A Chopin treated accidentals almost like key signature accidentals – he considered them to be valid in all octaves on a given stave and in a given clef. Therefore, in the R.H. part the last entered accidental is a  to d1, while in the L.H. part it is the sharps to Df and all starting from d2 that are missing. All necessary accidentals – assuming that they are also valid for notes at the same pitch under the octave sign – were added already in GE (→FE,EE, in the latter the notes under the octave sign were also provided with accidentals).

b. 363-366

composition: Op. 2, Variations, complete

..

As before (bars 349-352), in A Chopin writes accidentals only to the top notes of the octaves (in the R.H. and in the L.H.). He then considers these accidentals to be valid throughout an entire bar in all octaves of a given stave. All the omitted accidentals – 27 flats to d and g and 2 naturals to e – were already added in GE1 and were repeated in the remaining editions.
In the main text we omit the  to the d3 semiquaver in bar 363, unnecessarily repeated by Chopin. We do not include the  to the next semiquaver, d2, either, added in GE (→FE,EE).

b. 367-368

composition: Op. 2, Variations, complete

..

In A a few necessary naturals restoring the right pitch to the previously altered notes are missing – to g2c3e3 in bar 367 and to c3 in bar 368. In GE1 (→FE,EE,GE2FESB) only the second one was added, while in GE3 a third one was also added.
