Looking at the notation of the 2nd L.H. crotchet in A, one can have doubts whether it contains the c1 note, as one cannot see there a round notehead thereof, similar to g or d1. Its presence is proven by the fact that this crotchet's stem is clearly thicker, which is sometimes the only graphic element indicating the existence of a note on a ledger line in Chopin's autographs – cf., e.g. c1 at the beginning of the next bar, as well as some c3 and c4 in bars 231-235. The final assessment of such situations largely depends on the context, which in this place clearly supports the presence of c1 – this crotchet continues the sound plane initiated by the minim chords from the three previous bars, out of which each includes c1.
