b. 156

composition: Op. 12, Variations in B♭ major

Wedge in FE

No markings in GE & EE

..

The absence of the marks in GE and EE must be due to oversight, partially caused by the FE layout, in which the wedge was placed very close to the dashes marking the range of the octave sign. A similar situation occurred in bar 151.

 in FE (→EE)

..

The minor traces of corrections performed in print, visible in FE, suggest that a  was inserted there in place of . Therefore, the mark in GE would be a remaining element of an earlier version, perhaps misinterpreted by the FE engraver (from the manuscript). These marks can be difficult to tell apart in Chopin's autographs, and when they concern small rhythmic values, they are often equivalent.

4 wedges in FE (→EE)

1 staccato dot in GE

5 wedges suggested by editors

..

The missing 3 marks in GE are most probably due to oversight. On the other hand, the change of the FE wedges (→EE) to staccato dots resulted from general revision carried out by the publisher, which we summarise in separate notes (on this page in bar 145). In the main text in bar 162 we alternatively suggest supplementing the FE version (→EE) with a wedge over the 4th quaver.

Dotted crotchet in FE

Crotchet in GE & EE

..

In the case of such a small element as an augmentation dot, put in an atypical place, a double, independent oversight cannot be completely ruled out. However, it seems more likely that Chopin added this dot in the last stage of proofreading FE, after the copies serving as the bases for GE and EE had been sent.
