b. 106-109

composition: Op. 23, Ballade in G minor

..

In A, 8 accidentals are missing: naturals to e in b. 106, e1 in b. 106, 107 and 109, b and b2 in b. 108 and sharps to c3 in b. 107 and f1 in b. 108. FE (→GE1GE2,GE1a) added 5 accidentals, as a result of which it was only the naturals to e1 in b. 107 and 109 and to b2 in b. 108 that were missing. The mark in b. 109 was added by EE, while the one in b. 108 by GE3 (→GE4) and EE3. None of the sources includes the natural to e1 in b. 107.
(Due to the 4th L.H. crotchet in b. 107-108 having been placed on the top stave in A, a  to c1 in b. 107 and a  to b in b. 108 are missing too. In the layout adopted by the editions and in our transcriptions, these accidentals are not necessary.)

The fact that the missing naturals in A (→[FC]FEEE1) resulted from Chopin's mistake is proven by the harmonic sequence in analogous bar 273, featuring an E chord, and not an E minor chord, as well as by the regularity of the R.H. major third chromatic sequences in bars 101-109.

In A one can see that Chopin initially wrote the 3rd L.H. crotchet an octave higher, as B-b.

b. 106

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

..

At the beginning of the bar, in IE the crotchet in the bottom R.H. voice is an f, which is a mistake.

The abbreviated indication acceler. in A is repeated only in FE. GE and EE give the indication in its full form. In EE the indication accelerando was divided into syllables, which is a characteristic feature of that edition. In FE it is likely that the shift of acceler. over the last group of quavers may be an inaccuracy of the base text's recreation.
