The single-voice notation of the 1st chord in bars 26 and 28 in JC and EF is probably inaccurate: the notation of JC in bars 25 and 27 is a proof that Chopin did not precisely determine the bass note's extensions in [AI]. In the main text we give the notation of PE in both bars in the form used in bar 26; it guarantees a consistent division into voices, in which the two-note chords struck on strong beats of bars 25-26 have the value of quavers. Cf. bar 30.
As the 2nd quaver in bar 26, JC features the most probably erroneous a1. See the note related to the 4th quaver of that bar.
