In FED Chopin marked in an abbreviated manner an extension of the figuration with an octave (in pencil). A similar solution can be found in the Etude in F minor, Op. 25 No. 2, bar 67, the Nocturnes in F
minor, Op. 48 No. 2, bars 113-114 and in E major, Op. 62 No. 2, bars 68-69 and in the Waltz in A
major, Op. 34 No. 1, bars 163-164 and 167-168. In some of the cases, the idea of the variant could have been related to the extended piano scale, which in Chopin's last years reached until a4.
