Rhythm

b. 1

composition: Op. 10 No 10, Etude in A♭ major

Crotchet in A

Quaver in FE (→GE,EE)
..

A crotchet as the rhythmic value of the upbeat in A could have been related to the original accentuation of bars 1-4, determining the crotchet beat. Moreover, it cannot be excluded that Chopin had in mind a dotted crotchet – cf. minims in the L.H. in bars 1-3 and 5-6, as well as crotchets in bars 4 and 7). In each case a quaver flag in FE (→GE,EE) was probably added by Chopin, therefore we adopt the version with the quaver to the main text (in FE an uncorrected crotchet rest was left in the L.H., which was corrected in GE and EE).

b. 3-6

composition: Op. 10 No 10, Etude in A♭ major

Minims in A (→FE→GE,EE)

Crotchets suggested by the editors
..

The notation of e notes as minims, used by Chopin in bars 1-3 and 5-6, despite being formally incorrect in the case of the ones featured in the 2nd half of each of these bars, seems to be completely clear and it was not questioned. However, in bars 3 and 6 the 2nd minim means sustaining e also in the 1st half of bars 4 and 7, based on the B7 chord. Such a harmonic mix was rather not Chopin's aim. In A one can see that the minims were being added and probably the composer mechanically copied the notation, without considering the different harmonic situation. Due to this fact, in the main text we suggest to shorten the last e in bars 3 and 6 to a crotchet.

b. 7-8

composition: Op. 10 No 10, Etude in A♭ major

Crotchets in A

Quavers in FE (→GE,EE)
..

Lack of extensions of c1 and b in FE (→GE,EE), written in A in bars 7 and 8, is most probably an oversight of the engraver.

composition: Op. 10 No 10, Etude in A♭ major

Tie in A

No tie in FE (→GE,EE)
..

Oversight of the tie by the engraver of FE (→GE,EE) seems to be more plausible here than Chopin's possible proofreading in FE. Similarly in bars 52-53.

composition: Op. 10 No 10, Etude in A♭ major

Tie in A, GE & EE

No tie in FE
..

Same as in bars 50-51, we consider the omission of the tie by the engraver of FE to be more plausible than Chopin's possible proofreading of FE. However, in this place a tie was added both in GE and EE.
