Despite the fact that the a
2-a3 octave is possible as far as the sound is concerned (cf. the Prelude in F
minor, Op. 28 No. 8, bars 6 and 20), Chopin's mistake seems to be almost certain here, even due to the pianistic issues. The conclusion is confirmed by Chopin's proofreading performed in this place in FE (→GE,EE).
