Slur over quavers in FE (→GE,EE)

Slur to crotchet suggested by editors

..

Taking into account the fact that the slurs in similar situations in bar 19 and 22 encompass the entire motif of the L.H. top voice, we consider the FE slur (→GE,EE) to be inaccurate; in the main text we suggest leading it to the e1-c2 crotchet.

We add a cautionary  to e1 in the main text.

..

In FE a G-f seventh was printed by mistake instead of an F-f octave, which was corrected in GE and EE.

Wedge to a2 in FE

No marks in GE

2 wedges in EE

2 wedges suggested by editors

..

In the main text we suggest adding a wedge over f3. The next two such marks indicate the way the notes ending particular semiquaver groups should be played, both in this and the next bar, hence the omission of a respective mark over the first note of this kind must be considered an inaccuracy of notation. A wedge was also added in EE, whereas in GE the second mark was also overlooked, over a2.

composition: Op. 12, Variations in B♭ major

Slur to a3 in FE (→GE,EE)

Slur to f3 suggested by the editors

..

The FE slur is inaccurate – it ends between the 4th and 5th semiquaver. We reproduce it – as in GE and EE – as a slur encompassing the 1st beat only. On the other hand, in the main text we suggest a slur encompassing the entire R.H. figure, in accordance with the subsequent figures.
