b. 71-85

composition: Op. 26 No 1, Polonaise in C♯ minor

..

In A bars 71-85 are written in an abbreviated manner as numbered (1-15) empty bars, corresponding to repeated bars 39-53. Due to this reason, all differences in the editions between analogous places of both groups of bars are almost certainly incompatible with Chopin's intention and they result from inaccuracies of his corrections or oversights of the engravers.

Triad g-a-e1 in A (→FEGE1,EE)

Sixth g-e1 in GE2 (→GE3GE4GE5)

..

In analogous bar 43 Chopin deleted a in the 3rd quaver in the L.H. in the proofreading of FE1. Therefore the absence of a respective correction in bar 75 is most probably an inadvertence by the engraver or Chopin. The revisers of GE2 (→GE3GE4GE5) most probably rightly deleted this note, having compared the analogous bars.
Starting with GE3 a flat reinstating g was erroneously replaced by .

Long accent in A

Short accent in FE (→GE,EE)

FE (→GE,EE) rendered a clearly long accent in A as short, a patent imprecision.
