b. 91-92

composition: Op. 42, Waltz in A♭ major

FE1 i FEG (→GE)

Rhythm in FE0 (→EE), interpretation

..

The version of FE0 (→EE), in which the last semiquaver in bar 91 is linked with a beam to a quaver in bar 92, is certainly a mistake. It is hard to state clearly whether this error follows exclusively from the engraver's oversights or whether it was also some inaccuracies in Chopin base text that contributed to it. As a consequence, the first of the errors resulted in a change of the 1st value in bar 92 from a crotchet to a quaver and most probably it contributed to further rhythmic displacements: a too early placing of the quaver rest and a possible omission of the R.H. in the 2nd half of the bar (see the adjacent note). Chopin apparently did not correct this mistake in the base text to EE, yet the quaver rest was printed correctly, on the 2nd crotchet. To the main text we adopt the unambiguous version of FE1 and GE, confirmed by Chopin proofreading of FEG and similar rhythmic arrangements in bars 99-100.

b. 92-95

composition: Op. 42, Waltz in A♭ major

Literal reading of FEG (→GE1)

 
 
..

Chopin added a slur in FEG, ending it together with the bar line. It was only the engraver of GE1 that interpreted it literally, by placing the slur only in bar 94. There is no doubt that Chopin's intention was to lead the slur to the end of the phrase, i.e. the 1st crotchet in bar 95. The latter is included in EE, a relevant correction was also performed in GE2 (→GE3). FE does not have any slur in bars 92-95 at all.

b. 92

composition: Op. 42, Waltz in A♭ major

..

It seems that the second half of the R.H. in this bar was not printed in FE0. It may be a consequence of earlier rhythmic errors (see the previous note). The photocopy of FEG we have at our disposal does not let us state clearly which elements of the score were printed. Chopin certainly added a beam combining two quavers with a semiquaver, a semiquaver rest and a beam for the last semiquaver. Taking into account the rhythmic synchronisation of the hands, in FE0 could already have a quaver on the 2nd beat (misprinted in this place or possibly inaccurately added by Chopin in FEG) and the last semiquaver.

b. 92-95

composition: Op. 42, Waltz in A♭ major

One slur in FEG (literal reading→GE1)

One slur in FEG (interpretation) & EE

No slur in FE

Two slurs in GE2 (→GE3)

..

Chopin added a slur in those bars to FEG, it is also present in EE. Although a fragment of the slur visible on the available photograph reaches only the bar line after bar 94 (on this basis GE1 ends the slur on the last quaver of this bar), the shape of the line nevertheless suggests a continuation into bar 95. In GE2 (→GE3) the slur was prolonged up to bar 95, but also arbitrarily divided into two parts in bar 92. FE does not have any slur in this passage.
