Rhythm

b. 48

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

Crotchet in A

Minim in FE (→GE,EE)

..

Chopin extended the sound of three lower notes of the chord in a proofreading of FE (→GE,EE).

b. 65

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

Rhythm in A

FE (→GE,EE)

..

The change of the rhythmic configuration in the 1st triplet performed in a proofreading of FE (→GE,EE) is an example of a characteristic rhythmic variant, frequently encountered in Chopin's works (cf. Scherzo in C minor, Op. 39, bar 47). The uniform spacing of notes and a small, clearly inserted rest show that initially Chopin wrote a plain semiquaver triplet there, the correction in FE being only the last stage of changes at this place.

b. 66

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

Crotchet c1 in A

Minim c1 in FE (→GE,EE)

..

Chopin prolonged the sound of c1, while proofreading FE (→GE,EE). It is a continuation of the change whose traces are visible in A – initially the entire five-note chord was written in crotchets.

b. 72-73

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

No tie to d2 in A & EE2

d2 tied in FE (→GE) & EE3 (→EE4)

..

Lack of the tie sustaining d2 in A is most probably Chopin's oversight. The tie was added in a proofreading of FE (inaccurately – the tie in bar 72 at the end of the line was omitted), it is also included in GE. The hold of this note is also indicated by the fingering added by Chopin in FED. In EE2 the tie was overlooked, which was corrected in EE3 (→EE4).

b. 85

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

Minim in A

Semibreves in FE (→GE1GE2, →EE2EE3)

Minims in GE3 (→GE4GE5)

..

Despite the fact that the correct text is actually undeniable, its correct notation in the sources appears only in GE3 (→GE4GE5). The notation of A is unclear in terms of division into voices (hands), which may have resulted in a rhythmic error of FE (→GE1GE2, →EE2EE3). In turn, at the time of adding minim stems in EE4, the G note was omitted.
