b. 21

composition: Op. 64 No 1, Waltz in D♭ major

No indication in A (→FEGE,EE)

in AIII

..

We do not suggest the leggiero indication, one of two appearing in AIII, in the main text, since in the published version Chopin gave it already at the beginning of the Waltz. Moreover, it is not clear whether it can be considered to be independent from the accompaniment, which in AIII takes the form used in the version of A (→FEGE,EE) only eight bars later.

b. 21-23

composition: Op. 64 No 1, Waltz in D♭ major

L.H. minims in As, AI, AII & AIII

Crotchets in A (→FEGE1op,GE1Db,EE)

Crotchets &  e1 in GE2op (→#GE3op) & EEW1 (→EEW2)

..

Already in As, Chopin wrote two versions of accompaniment in these bars and in bar 24, however, it is not clear how he planned to use them. Eventually, in all later sources they were used to diversify the repeating figures through differentiation of the part of the L.H. in bars 21-24 and 29-32. The presentation autographs and the published version differ, however, in the order of appearance of both versions – apart from minor details, AI, AII and AIII first include the "tenor" version, which in A (→FEGE,EE) appears only as the second.
In order to preserve the continuity of the bass line after a possible version change, in the context of this note, one has to choose one of the corresponding variants in bars bar 20 and bar 24.

In the main text we add a cautionary  before e1 in bar 21, after the authentic sign before g1 in bar 23.

b. 21-24

composition: Op. 64 No 1, Waltz in D♭ major

..

In the version with the bass line, led with minims in the tenor register, Chopin wrote rests for the top voice of the L.H. (over the minims) only in one of the autographs – AII.

b. 21-23

composition: Op. 64 No 1, Waltz in D♭ major

..

Chopin did not pay special attention to cautionary flats before the e1 and gnotes in bars 21 and 23. The first was written only in AIII, it was also added in GE2op (→#GE3op) and EEW1 (→EEW2). The second is present in the majority of the sources – it was overlooked only in AII and GE2Db (→GE3DbGE4Db).

composition: Op. 64 No 1, Waltz in D♭ major

6 notes in As

7 notes in remaining sources

..

The part of the R.H. in bars 21 and 23 is written in As in two versions of an unidentified purpose. In the suggested reconstruction of the sketch we place the original, six-quaver version for the first time (bars 21 and 23), whereas the later, which starting from the presentation autographs became the only one, for the second time (bars 29 and 31).
