b. 83-84

composition: Op. 64 No 2, Waltz in C♯ minor

Continuous slur in AI

Separate slurs in A (→FEGE,EE)

..

Starting a new slur in bar 84 could have been related to a presence of an irregular group, since Chopin would generally instinctively encompass them with a separate slur. Therefore, the continuous slur of AI may be, according to us, considered an equal variant.

b. 84-85

composition: Op. 64 No 2, Waltz in C♯ minor

No tied notes b in As & AI

Tied notes b in A (→FEEE) & GE2no2

Tied note b in GE1op (→GE2opGE3op) & GE1no2

..

As in bars 68-69 Chopin did not mark the sustention of the note b in the earlier autographs. The tie was also omitted in most GE (except GE2no2). If not an error by the engraver of GE1op & GE1no2, this could indicate that the tie was added in FE in the last stage of proofreading (despite its presence in A).

As, 2nd version

A (→FEGE,EE)

..

The first of the versions of As, intended most probably for this bar, is already very close to the final one. In this situation, the presence of a considerably simpler and undoubtedly earlier version in AI may be puzzling – see bar 83. The interpretation of the second version of As is, due to a sketchy notation, hypothetical to a certain extent – the pitch of the second of the added notes is not entirely certain, whereas the last one could have been supposed to be an a1, like in the first version.

b. 84-85

composition: Op. 64 No 2, Waltz in C♯ minor

..

The slur over the three-note, chromatic progression of bass is only in the version prepared for print. In GE2no2, it was omitted, probably seeing in it a distorted tie of b.

Pedalling in EEC

Pedalling in GE2no2

..

The  sign in A is placed clearly after the 1st crotchet in the L.H., which, as it seems, was accurately reproduced in FE (→GE1no2,EEW1EEW2). Chopin probably wanted to preserve the sound of the e bass note, yet he also wanted to avoid the mixture of the melodic semitones of the triplet in the R.H., which can be achieved by pressing the pedal only on the last note of the triplet. In EEC and GE2no2, the notation was considered to be inaccurate, in turn, in GE1op (→GE2opGE3op) the indications were generally omitted, probably due to an oversight.
