The slur in A begins over the penultimate note in bar 16, yet Chopin undoubtedly thought of a
3 as the first note under the slur and so it was recreated in the editions. According to us, it is, however, very likely that Chopin mistook the last group in bar 16 with the first group in bar 17, which also starts with a3. At the time of writing the slur, the composer, in haste, could have considered the beginning of the octave sign as coinciding with the beginning of the new phrase, which he probably wanted to embrace with the slur.
