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.

In the main text we include the bottom notes of the octaves added – almost certainly by Chopin – in the stage of proofreading FE1. It is an indisputable enhancement, both due to a fuller sound of the ninth chord and due to the fidelity of the piano reduction to the orchestral original – the added notes correspond to the authentic Double Basses part in all sources of the orchestra part. The addition was also introduced into EE3, most probably pursuant to FE2.
