b. 260

composition: Op. 21, Concerto in F minor, Mvt III

Looking at the notation of the L.H. in A, one can see that the  sign is written under a1, the 1st note of the triplet on the 2nd beat of the bar, whereas the  sign under g1, the 2nd note. According to us, Chopin was writing pedal change while looking at the R.H., since the change is undoubtedly related to the appearance of a new trilled note. Due to this reason, we interpret the pedalling of A in the main text in this way.

Chopin added the octave bass sequence in the 2nd half of the bar while proofreading FE1. This addition, undoubtedly drawn from FE, was also introduced into EE3. According to us, it is likely that the composer wanted this unquestionable improvement of the version for one piano to apply to the version of the piece with orchestra too (as a complement to the cellos and the double basses). A few years later, also exclusively in the version for one piano, Chopin introduced a change into the first tutti in mov. III of the Concerto in F minor, Op. 21. It is also there that we can assume that the changed text was supposed to concern the orchestral part also in the full version of the piece.
