b. 67

composition: Op. 10 No 3, Etude in E major

Semiquavers in AI & FE (→GE,EE2)

Crotchet in A

Semiquavers with slur in EE3 (→EE4)

..

The version of A seems to be only a temporary deviation from the original concept, as at the time of proofreading FE (→GE,EE), Chopin returned the semiquaver figure, used before in AI (as repetition of the motif from bar 14). We add a slur over the semiquavers, by analogy with the slur added by Chopin in a proofreading of FE (→GE,EE) in bar 14, as well as with the slurs in analogous bars 15 (proofreading of FE) and 68 (A). This addition was already introduced in EE3 (→EE4).

b. 68

composition: Op. 10 No 3, Etude in E major

..

In FE1 (→GE1), the bottom notes of the 3rd and 4th chords in the R.H. were replaced by mistake – e1 is on the 3rd semiquaver, while d1 on the fourth. The mistake – rather obvious compared with analogous bar 16 – was corrected in the subsequent GE and EE. In turn, in FE2 the correction was performed inaccurately, leaving the erroneous d1 in the 4th chord. It is worth mentioning that from the harmonic point of view, it is only the error on the 4th semiquaver that is striking; the version with e1 as the bottom note of both discussed chords would be perfectly possible.

composition: Op. 10 No 3, Etude in E major

Triad in AI

Sixth in A (→FEGE,EE)

..

The version of AI (written for bar 15) is earlier. In the main text we give the final editing of the remaining editions.

A & c1 in AI

c & c1 in A (→FEGE,EE)

..

Lack of the  before the 6th semiquaver of the bottom voice in AI means that in both bars it is to be a c1. Knowing the final version, one can doubt whether Chopin simply forgot about the  before this note. The use of as the 5th semiquaver in the L.H. is, however, a strong argument for the authenticity of the literally interpreted version of AI.

In A (→FEEE2EE3), there is no  before the last note in the R.H., which is a patent inaccuracy of the notation. In GE1 (→GE1a), the sign was completed in bar 74, while in the remaining editions – in both bars.

a in AI, A, EE & GE1a (→GE2GE3GE4GE5)

b in FE (→GE1)

..

The version of FE (→GE1) is most probably erroneous, which is confirmed by a handwritten correction in FES. The mistake was corrected also in EE and in the subsequent GE.
