Issues : Errors of A

b. 4-12

composition: Op. 10 No 5, Etude in G♭ major

..

In A d in bars 4 and 12 is a dotted minim. The mistake, corrected in FE (→GE,EE), probably stems from the original notation of the Etude in two-time longer rhythmic values. What is interesting is the fact that in bar 52 Chopin noticed and corrected this mistake while still writing A.

Crotchet in A

Quaver in FE (→GE,EE)

..

In A the first chord in the L.H. is a crotchet. The possible mistake (theoretically it could be considered as a simplified two-voice notation) was corrected in FE (→GE,EE).

e3 in A (→FEGE,EE)

g3 in FES

..

According to us, the change of e3 to g3 written by Chopin in FES is a correction of the error of A and the remaining sources. Locally, the version with e3 – in bars 23-24 – is perfectly correct, yet in combination with the following bar, the note does not find a natural continuation (to d3), and, what is more important, it significantly weakens the effect of the constant g3 note, being an axis of the combination of chords in bars 24 and 25. In addition, Chopin's fingering in this place suggests a more significant distance than a fifth.
