b. 91

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A the g note is a semibreve, which is a patent mistake, perhaps under the influence of the notation in the previous bar. The correct rhythmic value intended by Chopin (minim) was introduced already by GE (→FE,EE,IE).

b. 91-95

composition: (Op. 4), Sonata in C minor, Mvt IV

No fingering in A (→GEFE,IE)

In the main text, we do not include the inauthentic R.H. fingering added by EE in bars 91 and 95.

b. 92

composition: (Op. 4), Sonata in C minor, Mvt IV

Semibreve d1 in A (→GEEE)

Minim in FE & IE

..

The d1 minim in FE and IE most probably resulted from the awkward GE notation, in which the noteheads of the minims and the semibreves are identical.

Long accent suggested by the editors

..

According to us, the  mark is to be interpreted here as a long accent. The literal interpretation, reproduced quite faithfully in GE, was gradually distorted by the subsequent editions, which made it increasingly different from the original notation.

..

The first L.H. octave is written in A in shorthand with the help of 8. In GE (→FE,EE,IE) it was written out in full.
