b. 4-11

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

In CLI all octaves in bars 4-11 (and many subsequent ones) are briefly written with the use of the 8 digit under the upper notes. In FE the notation was used only in the case of the quavers in bar 5 and the entire bar 6 (originally probably also in bars 7-8 and subsequent ones), while in GE1 of bars 6-8.

Ties in CLI, GE & EE

No ties in FE

..

In FE there are no ties sustaining the upper notes of the octaves in bars 7-8, 9-10 and 11-12. According to us, the most probable explanation is a kind of misunderstanding at the time of changing the original brief notation of the octaves with the use of under the upper notes for regular notation.

Octaves in FE & EE3

..

The AsI version is the original redaction of the bass part in this bar. In the main text we include the bottom notes of the octaves added – almost certainly by Chopin – in the stage of proofreading FE1. The addition was also introduced into EE3, most probably pursuant to FE2.
