b. 20

Pedalling in A

Pedalling in GE1op & GE1no2

No pedalling in GE2op (→GE3op)

No pedalling indications in this bar is most probably a result of revision of GE2op (→GE3op), aiming at unifying bar 4 and 20. As far as the placement of the  sign is concerned, it is only the version of A that is authentic, the remaining are most probably a result of a routine interpretation of indications by engravers or simply an inaccuracy in reproducing the base text.

 in A, EEw1 (→EEW2) & GE2op (→GE3op)

 in FE (→GE1op,GE1no2)

 in EEC & GE2no2

..

The  hairpin was inaccurately reproduced in the editions – already in FE (→GE1op,GE1no2) the sign is clearly shorter, which in the remaining editions was subject to further distortions or revisions. The compatibility of the sign's range in A and GE2op (→GE3op) and EEW is a result of overlapping of arbitrary, yet contrary changes.

Pedalling in A & GE2no2

No pedalling in FE (→EE,GE1no2,GE1opGE2opGE3op)

..

No pedalling in the editions – the indications were added only in GE2no2 – is almost certainly a mistake of the engraver of FE. Similarly in bar 30.

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

..

The  sign was overlooked in EEW1, which is certainly an error. The sign was added in EEW2.

No sign in the sources

 suggested by the editors

..

In the main text we suggest adding a  sign in this bar due to analogy with bar 9, yet above all due to the hairpin written in A in closely analogous bar 153.
