b. 205

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

Crotchet f1 in A, probable interpretation

Crotchets g1 f1 in A, possible interpretation

No crotchets in GE (→FE,EE,IE)

..

The little vertical line visible in A close to the g1 quaver could be the first of a series of additional crotchet stems prolonging the top notes of the broken L.H. octaves. However, according to us, it is more likely that this series starts from f1, which draws our attention to the harmonic sequence, which becomes more functional from this place on – two perfect cadences in C minor and a modulation to G. The omitted crotchet stem to f1 in the editions is most probably a mistake.

b. 206

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

Crotchet f1 in A

Crotchet c1-f1 in GE

Crotchet c1 in FE, EE & IE

..

In GE the change of the stems' direction forced a change to the arrangement of voices on the 7th quaver in the bar. In the main text we keep the A notation, in which it is only f1 that is prolonged to a crotchet. The GE version, equally justified in terms of harmony, can be considered an acceptable variant. On the other hand, the versions of the remaining editions certainly distort Chopin's intention.

b. 216

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

Quavers in A

Crotchets in GE (→FE,EE,IE)

..

At the beginning of bar 216 and 220 in the main text we keep the typical, simplified A rhythmic notation. In GE (→FE,EE,IE) the rhythmic value of the top note was changed to a crotchet, most probably in order to complete the top voice rhythm.

b. 225

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

Crotchet d3 in A (→GE)

Quavers in EE & IE

Crotchet b2 in FE

..

In GE we can see traces of removal of the top quaver beam and the stem to f2, which are present in the remaining editions. This means that the mistake consisting in printing them was committed in GE and that the correct text of this edition resulted from proofreading, performed after the GE copies serving as bases were handed over to the other publishers. The FE version most probably resulted from an unfortunate revision of this initial, erroneous version.

b. 226

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

g2 tied in A (→GEFE,IE)

g2 repeated in EE

..

The missing tie to g2 is most probably an oversight by the engraver of EE1 (→EE2).
