The origin of the additional e
note present in the 1st chord in the bar in FE (→GE,EE) is unclear. Chopin could have added it at the time of proofreading FE, yet it seems more plausible that it was printed by mistake instead of g (Terzverschreibung) or B (the second possibility is indicated by the length of the arpeggio wave). Then the correct note was added, yet the erroneous one was not deleted, which is a characteristic error of engravers (the then printing technique made adding a note much easier than deleting it). Similar mistakes were often committed in other Chopin's works, e.g., in the Scherzo in B minor, Op. 20, bars 135 and 292, the Ballade in G minor, Op. 23, bar 171 and the Polonaise in A major, Op. 40 No. 1, bar 93. Cf. the remark concerning the Etude in G major, No. 5, bar 59.
