b. 16

composition: Op. 29, Impromptu in A♭ major

In FE there are no stems sustaining the first note of each triplet in the L.H. It is certainly an oversight.

The slur of FE is certainly erroneous. The source of the mistake may have been unclear notation of the handwritten base in which bar 16 was probably at the beginning of the next page (as in A).

We lead the diminuendo hairpins to the penultimate quaver after A. In FE and GE the hairpins are longer in both bars, while in EE they are much shorter in bar 17.

The end of the slur in A is unclear. Despite the prolonged ending of the slur in bar 17, the slurs in A are clearly separated here. Taking into account the characteristic panache of this autograph, we interpret that slur according to the notation in the remaining sources. In FE the slur begins in bar 16.

We add the fingering written by Chopin in FES in analogous bar 99.
