b. 103

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

..

In the L.H. part there is only one  in A, before the 1st crotchet. In GE (→FE,EE,IE) this patent inaccuracy was corrected by adding both necessary flats.

b. 104-107

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

No fingering in A (→GEFE,IE)

Fingering in EE

..

In the main text we omit the inauthentic R.H. part fingering added by EE in bar 104 and 106-107. See also bar 112 and 115-116 and 118-120 and 123-124.

b. 104

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

e1 repeated in A

e1 tied in GE (→FE,EE,IE)

e1 tied, our variant suggestion

..

The consistent complementary rhythm in analogous bar 102 and 66 and 226 suggests that Chopin overlooked the tie to e1. Therefore, in the main text we suggest adding it, in accordance with the version of the editions.

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.
