Issues : Cautionary accidentals

b. 8-24

composition: Op. 64 No 3, Waltz in A♭ major

..

In the main text we omit the cautionary  next to din bar 8, present in the sources. Chopin probably feared that bat the beginning of the bar may trigger an association with d2. Similarly in bar 24, which in A is marked as a repetition of bar 8.

In As (→A) there is no  next to c2, which, in this context, has to be considered an inaccuracy. The sign was added already in FE (→GE,EE).

b. 91

In A there is no cautionary  before a. In this context, it must be considered an oversight, particularly taking into account the fact that the sign was written in As. A natural was added in the proofreading of FE (→GE,EE).

b. 93-98

composition: Op. 64 No 3, Waltz in A♭ major

..

The notation of the accidentals in this fragment of A is inaccurate – there is not any flat lowering e2(1) to e2(1) in bars 94, 96 and 98. It is probably an echo of the draft notation of As, which is not only devoid of flats, but it includes naturals before e1 in bars 93 and 97. The signs were added in FE (→GE,EE).
