Single-voice notation in FC (→GE) & EE

Two-voice notation in FE

The bottom voice, separated only in FE, was most probably added by Chopin in the proofreading of this edition.

It is difficult to decide how the difference in the rhythmic value of the note occurred. The minim in FE can be the last element of separation of the bottom voice in the R.H. in bars 58-60 and due to this fact, we give it in the main text. However, one cannot entirely exclude an error of the engraver who could have relied on the minim note heads of the L.H.

b. 85-88

composition: Op. 25 No 5, Etude in E minor

..

GE arbitrarily added rests completing the bottom voice of the L.H. – two in bar 85 (only in GE2 and GE3) and one in bar 89 (in all GE). Rests in bar 85 were added also in EE3.

Most probably, only one of the two rhythmic values of the bass is authentic, however, it is hard to determine which one. It is easy to imagine both an incidental omission and an erroneous addition of a dot extending the minim. In the main text, we adopt the version which in analogous bar 50 appears as the only one.
The rest added in GE – and in EE3 after it – is an arbitrary addition (in GE1 in this and in the next bar, two crotchet rests were erroneously added in each bar).

The creation of the version of FC may be explained with an oversight of the copyist, who overlooked the dot and tie extending the sound of the d minim. It is also possible that Chopin omitted FC, while adding the sustention of d in the remaining Stichvorlage manuscripts (base texts to FE and EE) – the version of FC would be then the original version. In GE the version was completed with an arbitrary rest (in GE1 two rests were added erroneously).
