b. 27-28

composition: Op. 10 No 1, Etude in C major

..

In EE2 there are no ties sustaining the G1-G octave, which is almost certainly a mistake (cf. bars 30-31). See the previous remark.

No ties in CLI

Ties in FE (→GE,EE)

In CLI the lack of hold of the bass octave is most probably the copyist's error.

b. 43

composition: Op. 10 No 1, Etude in C major

..

The stem of the 2nd minim in the L.H. in FE reaches only the upper note, G, which results in the fact that the lower one, G1, seems as if it was a semibreve. In GE and EE the error was corrected.

Rests in CLI & GE (except GE3)

Our variant suggestion

..

The sources differ when it comes to the notation of rests at the end of these bars. The natural notation of CLI, in which the part of the R.H. ends with a rest, however, was not repeated in FE (→EE2EE3). As it is not certain whether omitting the rests was done on purpose by Chopin, in the main text we propose rests in brackets as a variant solution. After all, the difference has a rather ideological than practical character. In the remaining editions the rests are present, which is most probably a result of revisers' actions. In EE4 and GE3 both rests are in bar 45, which is most probably a mistake.

No ties in CLI

Ties in GE & EE

..

In FE there are no ties sustaining the upper notes of the octaves in bars 73-74 and 75-76. According to us, the most probable explanation is a misunderstanding at the time of changing the original abbreviated notation of the octaves with the use of under the upper notes for regular notation. In CLI the octaves, written in the described brief manner, are not sustained at all, which most probably is a mistake.
